Description

Technical Field

[0001] The present invention relates to a display device for dogs. More specifically, it relates to a display device for dogs that displays images considering the visual characteristics of dogs.

Background Art

[0002] Humans have cone cells that perform the function of perceiving colors. Humans have three types of cone cells, each sensitive to light of different colors. For example, human L cone cells are sensitive to colors between yellow and green, M cone cells are sensitive to light between cyan and blue, and S cone cells are sensitive to colors between blue and purple. Considering such human visual characteristics, display devices have been developed to display various colors by mixing red, green, and blue in appropriate proportions.

[0003] In contrast, dogs have two types of cone cells. Dogs recognize red and green as yellow and can distinguish colors only by combinations of blue and yellow. Also, unlike humans, dogs can more easily distinguish colors the closer they are to ultraviolet light. That is, unlike humans, dogs have the highest color sensitivity in blue.

[0004] Thus, since the visual characteristics of dogs are different from those of humans, humans and animals recognize the same image differently from each other.

Summary of the Invention

Problems to be Solved by the Invention

[0005] An object of the present invention is to provide a display device for dogs that converts input image data into image data considering the visual characteristics of dogs. However, the object of the present invention is not limited to the above-mentioned object and can be variously extended without departing from the spirit and scope of the present invention.

Means for Solving the Problems

[0006] To achieve the objectives of the present invention, a dog display device according to an embodiment of the present invention is characterized by including a display panel including pixels, a dog filter that generates dog image data based on input image data, and determines a second blue gradation value of the dog image data by summing a first blue gradation value and a correction value of the input image data, and a display panel drive unit that generates a data voltage based on the dog image data and supplies the data voltage to the pixels.

[0007] In dog mode, the display panel drive unit activates the dog filter and generates the data voltage based on the dog image data, and in human mode, it deactivates the dog filter and generates the data voltage based on the input image data.

[0008] The dog filter determines the second blue tone value by adding the first blue tone value and the correction value if the first red tone value of the input image data is greater than 0, and determines the second blue tone value if the first red tone value is 0.

[0009] The correction value increases as the first red tone value increases. The dog filter determines the second blue tone value by adding the first blue tone value and the correction value if the first red tone value of the input image data is greater than the first blue tone value, and determines the second blue tone value if the first red tone value is less than or equal to the first blue tone value.

[0010] The correction value is larger the greater the difference between the first red gradation value and the first blue gradation value. The dog filter determines the second blue tone value by adding the first blue tone value and the correction value if the first red tone value of the input image data is greater than the first blue tone value and the first red tone value is greater than the first green tone value of the input image data; if the first red tone value is greater than the first blue tone value and the first red tone value is less than or the same as the first green tone value, the first blue tone value is determined to be the second blue tone value; if the first red tone value is less than or the same as the first blue tone value and the first red tone value is greater than the first green tone value, the first blue tone value is determined to be the second blue tone value; and if the first red tone value is less than or the same as the first blue tone value and the first red tone value is less than or the same as the first green tone value, the first blue tone value is determined to be the second blue tone value.

[0012] The correction value is larger the greater the difference between the first red gradation value and the first blue gradation value. The correction value is larger the greater the difference between the first green tone value and the first blue tone value.

[0013] The correction value is larger the larger the sum of the difference between the first red gradation value and the first blue gradation value, and the difference between the first green gradation value and the first blue gradation value. The dog filter determines the second blue tone value by adding the first blue tone value and the correction value if the first green tone value of the input image data is greater than 0, and determines the second blue tone value if the first green tone value is 0.

[0014] The dog filter determines the second blue tone value by adding the first blue tone value and the correction value if the first green tone value of the input image data is greater than the first blue tone value, and determines the first blue tone value by the second blue tone value if the first green tone value is less than or equal to the first blue tone value.

[0015] The dog filter determines the second blue tone value by adding the first blue tone value and the correction value if the first green tone value of the input image data is greater than the first blue tone value and the first green tone value is greater than the first red tone value of the input image data. If the first green tone value is greater than the first blue tone value and the first green tone value is less than or the same as the first red tone value, the first blue tone value is determined to be the second blue tone value. If the first green tone value is less than or the same as the first blue tone value and the first green tone value is greater than the first red tone value, the first blue tone value is determined to be the second blue tone value. If the first green tone value is less than or the same as the first blue tone value and the first green tone value is less than or the same as the first red tone value, the first blue tone value is determined to be the second blue tone value.

[0016] The dog filter converts the first red gradation value of the RGB domain of the input image data into a sensitivity domain that takes into account the visual characteristics of dogs to generate a third red gradation value, converts the first blue gradation value of the RGB domain into the sensitivity domain to generate a third blue gradation value, and converts the first green gradation value of the RGB domain of the input image data into the sensitivity domain to generate a third green gradation value.

[0017] The dog filter determines the second blue tone value by adding the first blue tone value and the correction value if the third red tone value is greater than the third blue tone value, and determines the second blue tone value if the third red tone value is less than or equal to the third blue tone value.

[0018] The dog filter determines the second blue tone value by adding the first blue tone value and the correction value if the third red tone value is greater than the third blue tone value and the third red tone value is greater than the third green tone value. If the third red tone value is greater than the third blue tone value and the third red tone value is less than or the same as the third green tone value, the first blue tone value is determined to be the second blue tone value. If the third red tone value is less than or the same as the third blue tone value and the third red tone value is greater than the third green tone value, the first blue tone value is determined to be the second blue tone value. If the third red tone value is less than or the same as the third blue tone value and the third red tone value is less than or the same as the third green tone value, the first blue tone value is determined to be the second blue tone value.

[0019] The dog filter determines the second blue tone value by adding the first blue tone value and the correction value if the third red tone value is greater than the third blue tone value and the third green tone value is greater than the third blue tone value. If the third red tone value is greater than the third blue tone value and the third green tone value is less than or the same as the third blue tone value, the first blue tone value is determined to be the second blue tone value. If the third red tone value is less than or the same as the third blue tone value and the third green tone value is greater than the third blue tone value, the first blue tone value is determined to be the second blue tone value. If the third red tone value is less than or the same as the third blue tone value and the third green tone value is less than or the same as the third blue tone value, the first blue tone value is determined to be the second blue tone value.

[0020] The dog filter determines the second blue tone value by adding the first blue tone value and the correction value if the third green tone value is greater than the third blue tone value, and determines the second blue tone value if the third green tone value is less than or equal to the third blue tone value.

[0021] The dog filter determines the second blue tone value by adding the first blue tone value and the correction value if the third green tone value is greater than the third blue tone value and the third green tone value is greater than the third red tone value. If the third green tone value is greater than the third blue tone value and the third green tone value is less than or the same as the third red tone value, the first blue tone value is determined to be the second blue tone value. If the third green tone value is less than or the same as the third blue tone value and the third green tone value is greater than the third red tone value, the first blue tone value is determined to be the second blue tone value. If the third green tone value is less than or the same as the third blue tone value and the third green tone value is less than or the same as the third red tone value, the first blue tone value is determined to be the second blue tone value.

[0022] In order to achieve another object of the present invention, a display device for dogs according to the present invention includes a display panel including pixels, a dog filter that generates dog image data based on input image data and determines a second red gradation value of the dog image data by subtracting a correction value from a first red gradation value of the input image data, and a display panel driving unit that generates a data voltage based on the dog image data and applies the data voltage to the pixels.

[0023] When the first red gradation value is greater than 0, the dog filter determines the second red gradation value by subtracting the correction value from the first red gradation value, and when the first red gradation value is 0, the dog filter determines the first red gradation value as the second red gradation value.

[0024] When the first red gradation value is greater than a first blue gradation value of the input image data, the dog filter determines the second red gradation value by subtracting the correction value from the first red gradation value, and when the first red gradation value is less than or equal to the first blue gradation value, the dog filter determines the first red gradation value as the second red gradation value.

[0025] When the first red gradation value is greater than the first blue gradation value of the input image data and the first red gradation value is greater than a first green gradation value of the input image data, the dog filter determines the second red gradation value by subtracting the correction value from the first red gradation value; when the first red gradation value is greater than the first blue gradation value and the first red gradation value is less than or equal to the first green gradation value, the dog filter determines the first red gradation value as the second red gradation value; when the first red gradation value is less than or equal to the first blue gradation value and the first red gradation value is greater than the first green gradation value, the dog filter determines the first red gradation value as the second red gradation value; and when the first red gradation value is less than or equal to the first blue gradation value and the first red gradation value is less than or equal to the first green gradation value, the dog filter determines the first red gradation value as the second red gradation value.

[0026] When the first red gradation value of the dog filter is greater than the first blue gradation value of the input image data and the first green gradation value of the input image data is greater than the first blue gradation value, the correction value is subtracted from the first red gradation value to determine the second red gradation value. When the first red gradation value is greater than the first blue gradation value and the first green gradation value is less than or equal to the first blue gradation value, the first red gradation value is determined as the second red gradation value. When the first red gradation value is less than or equal to the first blue gradation value and the first green gradation value is greater than the first blue gradation value, the first red gradation value is determined as the second red gradation value. When the first red gradation value is less than or equal to the first blue gradation value and the first green gradation value is less than or equal to the first blue gradation value, the first red gradation value is determined as the second red gradation value.

[0027] To achieve still another object of the present invention, a display device for dogs according to the present invention includes a display panel including pixels, a dog filter that generates dog image data based on input image data and subtracts a correction value from the first green gradation value of the input image data to determine the second green gradation value of the dog image data, and a display panel driving unit that generates a data voltage based on the dog image data and applies the data voltage to the pixels.

[0028] Also, to achieve another object of the present invention, a display device for dogs according to the present invention includes a display panel including pixels, a dog filter that generates dog image data by increasing the blue ratio of input image data, and a display panel driving unit that generates a data voltage based on the dog image data and applies the data voltage to the pixels.

[0029] The dog filter converts the input image data in the RGB domain to input image data in the HSV domain, expands the blue interval of the color values ​​of the input image data in the HSV domain, and shrinks the red interval of the color values ​​of the input image data in the HSV domain to generate dog image data in the HSV domain, and generates dog image data in the RGB domain based on the dog image data in the HSV domain.

[0030] Furthermore, in order to achieve another objective of the present invention, the dog display device according to the present invention is characterized by including a display panel including pixels, a dog filter that increases the difference between the brightness of the red region and the brightness of the green region of the input image data to generate dog image data, and a display panel driving unit that generates a data voltage based on the dog image data and supplies the data voltage to the pixels. [Effects of the Invention]

[0031] The dog display device according to the present invention generates dog image data based on input image data, and includes a dog filter that determines a second blue gradation value of the dog image data by adding a first blue gradation value and a correction value of the input image data, thereby increasing the blue content of the displayed image.

[0032] The dog display device according to the present invention generates dog image data based on input image data, and includes a dog filter that determines a second red gradation value of the dog image data by subtracting a correction value from a first red gradation value of the input image data, thereby reducing the red content of the displayed image.

[0033] The dog display device according to the present invention generates dog image data based on input image data, and includes a dog filter that determines a second green tone value of the dog image data by subtracting a correction value from a first green tone value of the input image data, thereby reducing the proportion of green in the displayed image.

[0034] The dog display device according to the present invention can increase the proportion of blue, which dogs can distinguish relatively well, and decrease the proportion of yellow (i.e., the proportions of red and green), which dogs have relative difficulty distinguishing, by increasing the proportion of blue, decreasing the proportion of red, or decreasing the proportion of green. As a result, input image data can be converted into image data that takes into account the visual characteristics of dogs.

[0035] The dog display device according to the present invention can distinguish between red and green images by increasing the difference in brightness between the red and green regions of the input image data. This allows dogs, which have difficulty distinguishing between red and green, to distinguish between red and green images.

[0036] However, the effects of the present invention are not limited to those described above, and can be extended in various ways without departing from the spirit and scope of the present invention. [Brief explanation of the drawing]

[0038] The present invention will be described in more detail below with reference to the attached drawings. Figure 1a shows an example of a dog display device being used. As shown in Figure 1a, the dog display device is installed at a position (or height) where the dog can see it, and displays images based on image data that takes into account the dog's visual characteristics. By displaying images based on image data that takes into account the dog's visual characteristics, the dog's ability to concentrate on the image is improved. This will be explained in more detail below.

[0039] Figure 1b is a block diagram showing a dog display device 1000 according to an embodiment of the present invention. As shown in Figure 1b, the dog display device 1000 includes a display panel 100, a display panel drive unit 1100, and a dog filter 500. The display panel drive unit 1100 includes a drive control unit 200, a gate drive unit 300, and a data drive unit 400. In one embodiment, the drive control unit 200 and the data drive unit 400 are integrated on a single chip. In another embodiment, the drive control unit 200, the data drive unit 400, and the dog filter 500 are integrated on a single chip.

[0040] In one embodiment, the dog filter 500 is included in the drive control unit 200. In another embodiment, the dog filter 500 is integrated on a separate chip from the drive control unit 200. In yet another embodiment, the dog filter 500 is included in a host processor (e.g., a graphics processing unit; GPU).

[0041] The display panel 100 includes a display unit (AA) for displaying images, and a peripheral unit (PA) adjacent to the display unit (AA). In one embodiment, the gate drive unit 300 is mounted on the peripheral unit (PA).

[0042] The display panel 100 includes a plurality of gate lines (GL), a plurality of data lines (DL), and a plurality of pixels (P) electrically connected to the gate lines (GL) and data lines (DL). The gate lines (GL) extend in a first direction (D1), and the data lines (DL) extend in a second direction (D2) that intersects the first direction (D1).

[0043] The drive control unit 200 receives input image data (IMG) and input control signals (CONT) from the host processor. The drive control unit 200 also receives dog image data (DIMG) from the dog filter. For example, the drive control unit 200 receives dog image data (DIMG) in dog mode and input image data (IMG) in human mode. For example, the display panel drive unit 1100 generates data voltages based on dog image data (DIMG) in dog mode and generates data voltages based on input image data (IMG) in human mode. For example, the input image data (IMG) and dog data (DIMG) include red image data, green image data, and blue image data. In one embodiment, the input image data (IMG) and dog data (DIMG) further include white image data. The input control signals (CONT) include a master clock signal and a data enable signal. The input control signals (CONT) further include a vertical synchronization signal and a horizontal synchronization signal.

[0044] In Figure 1b, the drive control unit 200 is shown to receive dog image data (DIMG) and input image data (IMG), but it is not limited to this. For example, the drive control unit 200 can receive dog image data (DIMG) without receiving input image data (IMG) if there are no dog mode and human mode. In this case, the dog display device 1000 will display an image based only on the dog image data (DIMG). Also, for example, if the drive control unit 200 includes a dog filter 500, the drive control unit 200 will receive input image data (IMG) but will not receive dog image data (DIMG).

[0045] The drive control unit 200 generates a first control signal (CONT1), a second control signal (CONT2), and output image data (OIMG) based on the input image data (IMG), dog image data (DIMG), and input control signal (CONT).

[0046] The drive control unit 200 generates a first control signal (CONT1) for controlling the operation of the gate drive unit 300 based on the input control signal (CONT), and outputs it to the gate drive unit 300. The first control signal (CONT1) includes a vertical start signal and a gate clock signal.

[0047] The drive control unit 200 generates a second control signal (CONT2) for controlling the operation of the data drive unit 400 based on the input control signal (CONT), and outputs it to the data drive unit 400. The second control signal (CONT2) includes a horizontal start signal and a load signal.

[0048] The drive control unit 200 receives input image data (IMG), dog image data (DIMG), and input control signal (CONT) to generate output image data (OIMG). The drive control unit 200 outputs the output image data (OIMG) to the data drive unit 400.

[0049] The gate drive unit 300 generates a gate signal for driving the gate line (GL) in response to a first control signal (CONT1) input from the drive control unit 200. The gate drive unit 300 outputs the gate signal to the gate line (GL). For example, the gate drive unit 300 sequentially outputs the gate signal to the gate line (GL).

[0050] The data drive unit 400 receives a second control signal (CONT2) and output image data (OIMG) from the drive control unit 200. The data drive unit 400 generates a data voltage by converting the output image data (OIMG) into an analog voltage. The data drive unit 400 outputs the data voltage to the data line (DL).

[0051] The dog filter 500 generates dog image data (DIMG) based on input image data (IMG). Dog image data (DIMG) is image data that takes into account the visual characteristics of dogs. In other words, the dog filter 500 converts input image data (IMG) into image data that takes into account the visual characteristics of dogs (i.e., dog image data (DIMG)). A detailed explanation will follow later.

[0052] Figure 2 is a graph showing the color coordinates for humans and dogs. The x-axis of the color coordinates represents the proportion of red, and the y-axis represents the proportion of green. The numbers displayed in the color space (e.g., 460, 480, 500, 520, 540, 560, 580, 600, and 620) represent wavelengths in nanometers (this applies equally to all color coordinates below).

[0053] As shown in Figure 2, dogs perceive red and green as yellow, and distinguish colors only by the combination of blue and yellow. The color space displayed by the dog display device 1000 is determined to be the first color space (CS1), the second color space (CS2), and so on. Figures 27 and 36 below will be explained based on the second color space (CS2).

[0054] Figure 3a is a conceptual diagram showing an example of the dog filter 500 of the dog display device 1000 in Figure 1b, and Figure 3b shows an example of color change due to the dog filter 500 in Figure 3a. The left graph in Figure 3b shows the human color coordinates for the input image data (IMG), and the two graphs on the right show the human color coordinates and the dog color coordinates for the dog image data (DIMG), respectively.

[0055] As shown in Figures 1b, 3a, and 3b, the dog filter 500 generates dog image data (DIMG) based on the input image data (IMG), and determines the second blue gradation value (B') of the dog image data (DIMG) by adding the first blue gradation value (B) and the correction value of the input image data (IMG). If the first red gradation value (R) of the input image data (IMG) is greater than 0, the dog filter 500 determines the second blue gradation value (B') by adding the first blue gradation value (B) and the correction value, and if the first red gradation value (R) is 0, it determines the first blue gradation value (B) as the second blue gradation value (B'). The correction value is larger the larger the first red gradation value (R). For example, the correction value is greater than 0.

[0056] Each pixel includes a sub-pixel for displaying a red image, a sub-pixel for displaying a blue image, and a sub-pixel for displaying a green image. The display panel drive unit 1100 generates a data voltage to be applied to the sub-pixel for displaying a red image based on a first red gradation value (R) or a second red gradation value (R'), generates a data voltage to be applied to the sub-pixel for displaying a blue image based on a first blue gradation value (B) or a second blue gradation value (B'), and generates a data voltage to be applied to the sub-pixel for displaying a green image based on a first green gradation value (G) or a second green gradation value (G'). For example, the input image data (IMG) includes a first red gradation value (R), a first blue gradation value (B), and a first green gradation value (G) in the range of 0 to 255, and the dog image data (DIMG) includes a second red gradation value (R'), a second blue gradation value (B'), and a second green gradation value (G') in the range of 0 to 255. The values ​​in the range of 0 to 255 represent the grayscale levels displayed.

[0057] As mentioned earlier, dogs distinguish colors only using combinations of blue and yellow (dogs perceive red and green as yellow), and the closer they are to ultraviolet light, the easier it is for them to distinguish colors. In other words, dogs easily distinguish colors in the blue range. That is, dogs find it easier to distinguish colors in images with a high proportion of blue. When the first red gradation value (R) is greater than 0, the dog filter 500 adds the first blue gradation value (B) and the correction value to determine the second blue gradation value (B'). Therefore, when the first red gradation value (R) is greater than 0, the second blue gradation value (B') is greater than the first blue gradation value (B). In other words, the dog filter 500 converts the input image data (IMG) into dog image data (DIMG) with a high proportion of blue.

[0058] The correction value increases as the first red tone value (R) increases. The larger the first red tone value (R), the lower the blue content of the input image data (IMG). Therefore, the correction value increases as the first red tone value (R) increases.

[0059] The Dog Filter 500 determines the first blue tone value (B) as the second blue tone value (B') when the first red tone value (R) is 0. When the first red tone value (R) is 0, the blue content of the input image data (IMG) is already high, so the Dog Filter 500 simply determines the first blue tone value (B) as the second blue tone value (B').

[0060] Figure 4 is a conceptual diagram showing a dog filter 500 of a dog display device according to an embodiment of the present invention. The dog display device according to this embodiment is the same as the dog display device 1000 in Figure 1b, except for the dog filter 500. Therefore, the same reference numerals are used for identical or similar components, and redundant explanations are omitted.

[0061] As shown in Figures 1b and 4, the dog filter 500 converts the input image data (IMG) into dog recognition image data (IMG') that takes into account the visual characteristics of dogs through a conversion table, and then corrects the input image data (IMG) based on the difference between the dog recognition image data (IMG') and the input image data (IMG) to generate dog image data (DIMG).

[0062] The dog filter 500 generates dog recognition image data (IMG') by applying predetermined weight values ​​to the input image data (IMG) through a conversion table. For example, the image displayed based on the dog recognition image data (IMG') consists only of blue and yellow. In other words, the dog filter 500 can convert the input image data (IMG) into data corresponding to images that dogs actually recognize.

[0063] The dog filter 500 corrects the input image data (IMG) based on the difference between the dog recognition image data (IMG') and the input image data (IMG) to generate dog image data (DIMG). For example, the dog filter 500 corrects the input image data (IMG) by the difference mentioned above. For example, the dog filter 500 corrects the input image data (IMG) by the difference in grayscale between the dog recognition image data (IMG') and the input image data (IMG).

[0064] Therefore, the dog display device corrects the input image data by the difference between the data for the image the dog actually recognizes and the input image data, thereby displaying an image identical to the image the dog actually recognizes.

[0065] Figure 5a is a conceptual diagram showing a dog filter 500 of a dog display device according to an embodiment of the present invention, and Figure 5b is a diagram showing an example of color change by the dog filter 500 in Figure 5a. The left graph in Figure 5b shows the human color coordinates for input image data (IMG), and the two graphs on the right show the human color coordinates and the dog color coordinates for dog image data (DIMG), respectively.

[0066] The dog display device according to this embodiment is the same as the dog display device 1000 in Figure 1b, except for the process of generating dog image data (DIMG). Therefore, the same reference numerals are used for identical or similar components, and redundant explanations are omitted.

[0067] As shown in Figures 1b, 5a, and 5b, if the first red tone value (R) is greater than the first blue tone value (B), the first blue tone value (B) and the correction value are added together to determine the second blue tone value (B'). If the first red tone value (R) is less than or equal to the first blue tone value (B), the first blue tone value (B) is set as the second blue tone value (B'). The correction value is larger the greater the difference between the first red tone value (R) and the first blue tone value (B).

[0068] The Dog Filter 500 determines the second blue tone value (B') by adding the first blue tone value (B) and the correction value if the first red tone value (R) is greater than the first blue tone value (B). Therefore, if the first red tone value (R) is greater than the first blue tone value (B), the second blue tone value (B') will be greater than the first blue tone value (B). In other words, the Dog Filter 500 converts the input image data (IMG) into dog image data (DIMG) with a high blue content.

[0069] The correction value increases as the difference between the first red tone value (R) and the first blue tone value (B) increases. The larger the difference between the first red tone value (R) and the first blue tone value (B), the lower the blue content of the input image data (IMG). Therefore, the correction value increases as the difference between the first red tone value (R) and the first blue tone value (B) increases.

[0070] The dog filter 500 determines the first blue tone value (B) as the second blue tone value (B') if the first red tone value (R) is smaller than or equal to the first blue tone value (B). If the first red tone value (R) is smaller than or equal to the first blue tone value (B), the blue ratio of the input image data (IMG) is already high, so the dog filter 500 determines the first blue tone value (B) as the second blue tone value (B').

[0071] Figure 6a is a conceptual diagram showing a dog filter 500 of a dog display device according to an embodiment of the present invention, and Figure 6b is a diagram showing an example of color change by the dog filter 500 in Figure 6a. The left graph in Figure 6b shows the human color coordinates for input image data (IMG), and the two graphs on the right show the human color coordinates and the dog color coordinates for dog image data (DIMG), respectively.

[0072] The dog display device according to this embodiment is the same as the dog display device 1000 in Figure 1b, except for the process of generating dog image data (DIMG). Therefore, the same reference numerals are used for identical or similar components, and redundant explanations are omitted.

[0073] As shown in Figures 1b, 6a, and 6b, the dog filter 500 determines a second blue tone value (B') by adding the first blue tone value (B) and the correction value if the first red tone value (R) is greater than the first blue tone value (B) and the first red tone value (R) is greater than the first green tone value (G) for the green image data of the input image data (IMG). If the first red tone value (R) is greater than the first blue tone value (B) and the first red tone value (R) is less than or equal to the first green tone value (G), the first The blue tone value (B) is set as the second blue tone value (B'). If the first red tone value (R) is smaller than or equal to the first blue tone value (B), and the first red tone value (R) is larger than the first green tone value (G), then the first blue tone value (B) is set as the second blue tone value (B'). If the first red tone value (R) is smaller than or equal to the first blue tone value (B), and the first red tone value (R) is smaller than or equal to the first green tone value (G), then the first blue tone value (B) is set as the second blue tone value (B'). The correction value is larger the greater the difference between the first red tone value (R) and the first blue tone value (B).

[0074] The Dog Filter 500 determines the second blue tone value (B') by adding the first blue tone value (B) and the correction value if the first red tone value (R) is greater than the first blue tone value (B) and the first red tone value (R) is greater than the first green tone value (G). Therefore, if the first red tone value (R) is greater than the first blue tone value (B) and the first red tone value (R) is greater than the first green tone value (G), the second blue tone value (B') will be greater than the first blue tone value (B). In other words, the Dog Filter 500 converts the input image data (IMG) into dog image data (DIMG) with a high blue content.

[0075] The correction value increases as the difference between the first red tone value (R) and the first blue tone value (B) increases. The larger the difference between the first red tone value (R) and the first blue tone value (B), the lower the blue content of the input image data (IMG). Therefore, the correction value increases as the difference between the first red tone value (R) and the first blue tone value (B) increases.

[0076] The Dog Filter 500 determines the first blue tone value (B) as the second blue tone value (B') if the first red tone value (R) is greater than the first blue tone value (B) and the first red tone value (R) is less than or equal to the first green tone value (G). It also determines the first blue tone value (B) as the second blue tone value (B') if the first red tone value (R) is less than or equal to the first blue tone value (B) and the first red tone value (R) is greater than the first green tone value (G). Finally, it determines the first blue tone value (B) as the second blue tone value (B') if the first red tone value (R) is less than or equal to the first blue tone value (B) and the first red tone value (R) is less than or equal to the first green tone value (G). If the first red gradation value (R) is smaller than or equal to the first blue gradation value (B), the blue content of the input image data (IMG) is already high, so the dog filter 500 determines the first blue gradation value (B) as the second blue gradation value (B').

[0077] Figure 7a is a conceptual diagram showing a dog filter 500 of a dog display device according to an embodiment of the present invention, and Figure 7b is a diagram showing an example of color change by the dog filter 500 in Figure 7a. The left graph in Figure 7b shows the human color coordinates for input image data (IMG), and the two graphs on the right show the human color coordinates and the dog color coordinates for dog image data (DIMG), respectively.

[0078] The dog display device according to this embodiment is the same as the dog display device 1000 in Figure 1b, except for the process of generating dog image data (DIMG). Therefore, the same reference numerals are used for identical or similar components, and redundant explanations are omitted.

[0079] As shown in Figures 1b, 7a, and 7b, the dog filter 500 determines the second blue tone value (B') by adding the first blue tone value (B) and the correction value if the first red tone value (R) is greater than the first blue tone value (B) and the first green tone value (G) is greater than the first blue tone value (B). If the first red tone value (R) is greater than the first blue tone value (B) and the first green tone value (G) is less than or equal to the first blue tone value (B), the first blue tone value (B) is set to the second... If the first blue tone value (B') is determined to be a blue tone value, and the first red tone value (R) is smaller than or equal to the first blue tone value (B), and the first green tone value (G) is larger than the first blue tone value (B), then the first blue tone value (B) is determined to be a second blue tone value (B'). If the first red tone value (R) is smaller than or equal to the first blue tone value (B), and the first green tone value (G) is smaller than or equal to the first blue tone value (B), then the first blue tone value (B) is determined to be a second blue tone value (B'). The correction value is larger the greater the difference between the first red tone value (R) and the first blue tone value (B).

[0080] The Dog Filter 500 determines the second blue tone value (B') by adding the first blue tone value (B) and the correction value if the first red tone value (R) is greater than the first blue tone value (B) and the first green tone value (G) is greater than the first blue tone value (B). Therefore, if the first red tone value (R) is greater than the first blue tone value (B) and the first green tone value (G) is greater than the first blue tone value (B), the second blue tone value (B') will be greater than the first blue tone value (B). In other words, the Dog Filter 500 converts the input image data (IMG) into dog image data (DIMG) with a high blue content.

[0081] In one embodiment, the correction value is larger the greater the difference between the first red gradation value (R) and the first blue gradation value (B). The greater the difference between the first red gradation value (R) and the first blue gradation value (B), the lower the blue content of the input image data (IMG). Therefore, the correction value is larger the greater the difference between the first red gradation value (R) and the first blue gradation value (B).

[0082] In one embodiment, the correction value is larger the greater the difference between the first green tone value (G) and the first blue tone value (B). The greater the difference between the first green tone value (G) and the first blue tone value (B), the lower the blue content of the input image data (IMG). Therefore, the correction value is larger the greater the difference between the first green tone value (G) and the first blue tone value (B).

[0083] In one embodiment, the correction value is larger the larger the sum of the difference between the first red gradation value (R) and the first blue gradation value (B), and the difference between the first green gradation value (G) and the first blue gradation value (B). The larger the difference between the first red gradation value (R) and the first blue gradation value (B), and the larger the difference between the first green gradation value (G) and the first blue gradation value (B), the lower the blue content of the input image data (IMG). Therefore, the correction value is larger the larger the difference between the first green gradation value (G) and the first blue gradation value (B).

[0084] The Dog Filter 500 determines the first blue tone value (B) as the second blue tone value (B') if the first red tone value (R) is greater than the first blue tone value (B) and the first green tone value (G) is less than or the same as the first blue tone value (B). It also determines the first blue tone value (B) as the second blue tone value (B') if the first red tone value (R) is less than or the same as the first blue tone value (B) and the first green tone value (G) is greater than the first blue tone value (B). Finally, it determines the first blue tone value (B) as the second blue tone value (B') if the first red tone value (R) is less than or the same as the first blue tone value (B) and the first green tone value (G) is less than or the same as the first blue tone value (B). Since dogs perceive red and green as yellow, and blue as blue, if either the first red gradation value (R) or the first green gradation value (G) is smaller than or equal to the first blue gradation value, the blue content of the input image data (IMG) is already high. Therefore, the dog filter 500 simply sets the first blue gradation value (B) as the second blue gradation value (B').

[0085] Figure 8a is a conceptual diagram showing a dog filter 500 of a dog display device according to an embodiment of the present invention, and Figure 8b is a diagram showing an example of color change by the dog filter 500 in Figure 8a. The left graph in Figure 8b shows the human color coordinates for input image data (IMG), and the two graphs on the right show the human color coordinates and the dog color coordinates for dog image data (DIMG), respectively.

[0086] The dog display device according to this embodiment is the same as the dog display device 1000 in Figure 1b, except for the process of generating dog image data (DIMG). Therefore, the same reference numerals are used for identical or similar components, and redundant explanations are omitted.

[0087] As shown in Figures 1b, 8a, and 8b, the dog filter 500 determines the second blue tone value (B') by adding the first blue tone value (B) and the correction value when the first green tone value (G) is greater than 0, and when the first green tone value (G) is 0, it determines the second blue tone value (B') as the first blue tone value (B). The correction value is larger the larger the first green tone value (G) is. For example, the correction value is greater than 0.

[0088] The Dog Filter 500 determines the second blue tone value (B') by adding the first blue tone value (B) and the correction value if the first green tone value (G) is greater than 0. Therefore, if the first green tone value (G) is greater than 0, the second blue tone value (B') will be greater than the first blue tone value (B). In other words, the Dog Filter 500 converts the input image data (IMG) into dog image data (DIMG) with a high blue content.

[0089] The correction value increases as the first green tone value (G) increases. The larger the first green tone value (G), the lower the blue content of the input image data (IMG). Therefore, the correction value increases as the first green tone value (G) increases.

[0090] The dog filter 500 determines the first blue tone value (B) as the second blue tone value (B') if the first green tone value (G) is 0. If the first green tone value (G) is 0, the blue content of the input image data (IMG) is already high, so the dog filter 500 simply determines the first blue tone value (B) as the second blue tone value (B').

[0091] Figure 9a is a conceptual diagram showing a dog filter 500 of a dog display device according to an embodiment of the present invention, and Figure 9b is a diagram showing an example of color change by the dog filter 500 in Figure 9a. The left graph in Figure 9b shows the human color coordinates for input image data (IMG), and the two graphs on the right show the human color coordinates and the dog color coordinates for dog image data (DIMG), respectively.

[0092] The dog display device according to this embodiment has the same configuration as the dog display device in Figure 8a, except for the process of generating dog image data (DIMG). Therefore, the same reference numerals are used for identical or similar components, and redundant explanations are omitted.

[0093] As shown in Figures 1b, 9a, and 9b, the dog filter 500 determines the second blue tone value (B') by adding the first blue tone value (B) and the correction value if the first green tone value (G) is greater than the first blue tone value (B). If the first green tone value (G) is less than or equal to the first blue tone value (B), the first blue tone value (B) is set as the second blue tone value (B'). The correction value is larger the greater the difference between the first green tone value (G) and the first blue tone value (B).

[0094] The Dog Filter 500 determines the second blue tone value (B') by adding the first blue tone value (B) and the correction value if the first green tone value (G) is greater than the first blue tone value (B). Therefore, if the first green tone value (G) is greater than the first blue tone value (B), the second blue tone value (B') will be greater than the first blue tone value (B). In other words, the Dog Filter 500 converts the input image data (IMG) into dog image data (DIMG) with a high blue content.

[0095] The correction value increases as the difference between the first green tone value (G) and the first blue tone value (B) increases. The larger the difference between the first green tone value (G) and the first blue tone value (B), the lower the blue content of the input image data (IMG). Therefore, the correction value increases as the difference between the first green tone value (G) and the first blue tone value (B) increases.

[0096] The dog filter 500 determines the first blue tone value (B) as the second blue tone value (B') if the first green tone value (G) is smaller than or equal to the first blue tone value (B). If the first green tone value (G) is smaller than or equal to the first blue tone value (B), the blue ratio of the input image data (IMG) is already high, so the dog filter 500 determines the first blue tone value (B) as the second blue tone value (B').

[0097] Figure 10a is a conceptual diagram showing a dog filter 500 of a dog display device according to an embodiment of the present invention, and Figure 10b is a diagram showing an example of color change by the dog filter 500 in Figure 10a. The left graph in Figure 10b shows the human color coordinates for input image data (IMG), and the two graphs on the right show the human color coordinates and the dog color coordinates for dog image data (DIMG), respectively.

[0098] The dog display device according to this embodiment has the same configuration as the dog display device in Figure 8a, except for the process of generating dog image data (DIMG). Therefore, the same reference numerals are used for identical or similar components, and redundant explanations are omitted.

[0099] As shown in Figures 1b, 10a, and 10b, the dog filter 500 determines the second blue tone value (B') by adding the first blue tone value (B) and the correction value if the first green tone value (G) is greater than the first blue tone value (B) and the first green tone value (G) is greater than the first red tone value (R). If the first green tone value (G) is greater than the first blue tone value (B) and the first green tone value (G) is less than or equal to the first red tone value (R), the first blue tone value (B) is set to the second The first blue tone value (B') is determined to be the first blue tone value (G). If the first green tone value (G) is smaller than or equal to the first blue tone value (B), and the first green tone value (G) is larger than the first red tone value (R), then the first blue tone value (B) is determined to be the second blue tone value (B'). If the first green tone value (G) is smaller than or equal to the first blue tone value (B), and the first green tone value (G) is smaller than or equal to the first red tone value (R), then the first blue tone value (B) is determined to be the second blue tone value (B'). The correction value is larger the greater the difference between the first green tone value (G) and the first blue tone value (B).

[0100] The Dog Filter 500 determines the second blue tone value (B') by adding the first blue tone value (B) and the correction value if the first green tone value (G) is greater than the first blue tone value (B) and the first green tone value (G) is greater than the first red tone value (R). Therefore, if the first green tone value (G) is greater than the first blue tone value (B) and the first green tone value (G) is greater than the first red tone value (R), the second blue tone value (B') is greater than the first blue tone value (B). In other words, the Dog Filter 500 converts the input image data (IMG) into dog image data (DIMG) with a high blue content.

[0101] The correction value increases as the difference between the first green tone value (G) and the first blue tone value (B) increases. The larger the difference between the first green tone value (G) and the first blue tone value (B), the lower the blue content of the input image data (IMG). Therefore, the correction value increases as the difference between the first green tone value (G) and the first blue tone value (B) increases.

[0102] The Dog Filter 500 determines the first blue tone value (B) as the second blue tone value (B') if the first green tone value (G) is greater than the first blue tone value (B) and the first green tone value (G) is less than or equal to the first red tone value (R). It also determines the first blue tone value (B) as the second blue tone value (B') if the first green tone value (G) is less than or equal to the first blue tone value (B) and the first green tone value (G) is greater than the first red tone value (R). Finally, it determines the first blue tone value (B) as the second blue tone value (B') if the first green tone value (G) is less than or equal to the first blue tone value (B) and the first green tone value (G) is less than or equal to the first red tone value (R). If the first green tone value (G) is smaller than or equal to the first blue tone value (B), the blue content of the input image data (IMG) is already high, so the dog filter 500 decides that the first blue tone value (B) will remain as the second blue tone value (B').

[0103] Figure 11 is a graph showing the sensitivity of dogs and humans, and Figure 12 is a conceptual diagram showing the dog filter 500 of a display device according to an embodiment of the present invention. The graph on the left of Figure 12 shows the human color coordinates for input image data (IMG), and the two graphs on the right show the human color coordinates and the dog color coordinates for dog image data (DIMG), respectively.

[0104] The dog display device according to this embodiment is the same as the dog display device 1000 in Figure 1b, except for the process of generating dog image data (DIMG). Therefore, the same reference numerals are used for identical or similar components, and redundant explanations are omitted.

[0105] As shown in Figures 1b, 11, and 12, the dog filter 500 converts the first red gradation value (R) of the RGB domain into a sensitivity domain that takes into account the visual characteristics of dogs to generate a third red gradation value (R"), converts the first blue gradation value (B) of the RGB domain into a sensitivity domain to generate a third blue gradation value (B") in Figure 11, and converts the first green gradation value (G) of the RGB domain into a sensitivity domain to generate a third green gradation value (G") in Figure 12.

[0106] Humans are more sensitive to red than blue, and more sensitive to green than red. Unlike humans, dogs distinguish colors more easily as they get closer to ultraviolet light. In other words, unlike humans, dogs are most sensitive to blue. Therefore, the Dog Filter 500 can convert the RGB domain to a sensitivity domain that takes into account the visual characteristics of dogs, so that these characteristics of dogs are better reflected.

[0107] For example, to convert the RGB domain to the sensitivity domain, the dog filter 500 applies weights to a first red gradation value (R), a first green gradation value (G), and a first blue gradation value (B). A first weight is applied to the first red gradation value (R), a second weight is applied to the first green gradation value (G), and a third weight is applied to the first blue gradation value (B). Since dogs are most sensitive to blue, the third weight is greater than the first and second weights. Since dogs are more sensitive to green than to red, the second weight is greater than the first weight. For example, the third red gradation value (R"), the third blue gradation value (B in Figure 11), and the third green gradation value (G in Figure 12) are calculated using the following formulas.

[0108]

number

[0109] Here, R1 is the first red gradation value, G1 is the first green gradation value, B1 is the first blue gradation value, R3 is the third red gradation value, G3 is the third green gradation value, B3 is the third blue gradation value, S1 is the first weighted value, S2 is the second weighted value, and S3 is the third weighted value.

[0110] The dog filter 500 generates dog image data (DIMG) based on input image data (IMG), and determines the second blue gradation value (B') of the dog image data (DIMG) by adding the first blue gradation value (B) and the correction value for the blue image data of the input image data (IMG). If the third red gradation value (R") is greater than 0, the dog filter 500 determines the second blue gradation value (B') by adding the first blue gradation value (B) and the correction value, and if the third red gradation value (R") is 0, it determines the first blue gradation value (B) as the second blue gradation value (B'). The correction value is larger the larger the third red gradation value (R") is. For example, the correction value is greater than 0.

[0111] The Dog Filter 500 determines the second blue tone value (B') by adding the first blue tone value (B) and the correction value when the third red tone value (R") is greater than 0. Therefore, when the third red tone value (R") is greater than 0, the second blue tone value (B') is greater than the first blue tone value (B). In other words, the Dog Filter 500 converts the input image data (IMG) into dog image data (DIMG) with a high blue content.

[0112] The correction value increases as the third red tone value (R) increases. The larger the third red tone value (R) increases, the lower the blue content of the input image data (IMG). Therefore, the correction value increases as the third red tone value (R) increases.

[0113] The dog filter 500 determines the first blue tone value (B) as the second blue tone value (B') if the third red tone value (R") is 0. If the third red tone value (R") is 0, the blue tone ratio of the input image data (IMG) is already high, so the dog filter 500 simply determines the first blue tone value (B) as the second blue tone value (B').

[0114] Figure 13 is a conceptual diagram showing a dog filter 500 of a dog display device according to an embodiment of the present invention. The graph on the left of Figure 13 shows the human color coordinates for input image data (IMG), and the two graphs on the right show the human color coordinates and the dog color coordinates for dog image data (DIMG), respectively.

[0115] The dog display device according to this embodiment is the same as the dog display device shown in Figure 12, except for the process of generating dog image data (DIMG). Therefore, the same reference numerals are used for identical or similar components, and redundant explanations are omitted.

[0116] As shown in Figures 1b and 13, if the third red tone value (R") is greater than the third blue tone value (B"), the first blue tone value (B) and the correction value are added together to determine the second blue tone value (B'). If the third red tone value (R") is less than or equal to the third blue tone value (B"), the first blue tone value (B) is set as the second blue tone value (B'). The correction value is larger the greater the difference between the third red tone value (R") and the third blue tone value (B).

[0117] The Dog Filter 500 determines the second blue tone value (B') by adding the first blue tone value (B) and the correction value if the third red tone value (R) is greater than the third blue tone value (B). Therefore, if the third red tone value (R) is greater than the third blue tone value (B), the second blue tone value (B') is greater than the first blue tone value (B). In other words, the Dog Filter 500 converts the input image data (IMG) into dog image data (DIMG) with a high blue content.

[0118] The correction value increases as the difference between the third red gradation value (R) and the third blue gradation value (B) increases. The larger the difference between the third red gradation value (R) and the third blue gradation value (B), the lower the blue content of the input image data (IMG). Therefore, the correction value increases as the difference between the third red gradation value (R) and the third blue gradation value (B) increases.

[0119] The dog filter 500 determines the first blue tone value (B) as the second blue tone value (B') if the third red tone value (R) is less than or equal to the third blue tone value (B). If the third red tone value (R) is less than or equal to the third blue tone value (B), the blue ratio of the input image data (IMG) is already high, so the dog filter 500 determines the first blue tone value (B) as the second blue tone value (B').

[0120] Figure 14 is a conceptual diagram showing a dog filter 500 of a dog display device according to an embodiment of the present invention. The left graph in Figure 4 shows the human color coordinates for input image data (IMG), and the two graphs on the right show the human color coordinates and the dog color coordinates for dog image data (DIMG), respectively.

[0121] The dog display device according to this embodiment is the same as the dog display device shown in Figure 12, except for the process of generating dog image data (DIMG). Therefore, the same reference numerals are used for identical or similar components, and redundant explanations are omitted.

[0122] As shown in Figures 1b and 14, the dog filter 500 determines the second blue tone value (B') by adding the first blue tone value (B) and the correction value if the third red tone value (R) is greater than the third blue tone value (B) and the third red tone value (R) is greater than the third green tone value (G). If the third red tone value (R) is greater than the third blue tone value (B) and the third red tone value (R) is less than or equal to the third green tone value (G), the first blue tone value (B) is set to the second blue tone value. If the third red gradation value (R) is set as (B'), and the third red gradation value (R) is smaller than or equal to the third blue gradation value (B), and the third red gradation value (R) is larger than the third green gradation value (G), then the first blue gradation value (B) is set as the second blue gradation value (B'). If the third red gradation value (R) is smaller than or equal to the third blue gradation value (B), and the third red gradation value (R) is smaller than or equal to the third green gradation value (G), then the first blue gradation value (B) is set as the second blue gradation value (B'). The correction value is larger the greater the difference between the third red gradation value (R) and the third blue gradation value (B).

[0123] The Dog Filter 500 determines the second blue tone value (B') by adding the first blue tone value (B) and the correction value if the third red tone value (R) is greater than the third blue tone value (B) and the third red tone value (R) is greater than the third green tone value (G). Therefore, if the third red tone value (R) is greater than the third blue tone value (B) and the third red tone value (R) is greater than the third green tone value (G), the second blue tone value (B') is greater than the first blue tone value (B). In other words, the Dog Filter 500 converts the input image data (IMG) into dog image data (DIMG) with a high blue content.

[0124] The correction value increases as the difference between the third red gradation value (R) and the third blue gradation value (B) increases. The larger the difference between the third red gradation value (R) and the third blue gradation value (B), the lower the blue content of the input image data (IMG). Therefore, the correction value increases as the difference between the third red gradation value (R) and the third blue gradation value (B) increases.

[0125] The Dog Filter 500 determines the first blue tone value (B) as the second blue tone value (B') if the third red tone value (R) is greater than the third blue tone value (B) and the third red tone value (R) is less than or equal to the third green tone value (G). It also determines the first blue tone value (B) as the second blue tone value (B') if the third red tone value (R) is less than or equal to the third blue tone value (B) and the third red tone value (R) is greater than the third green tone value (G). Finally, it determines the first blue tone value (B) as the second blue tone value (B') if the third red tone value (R) is less than or equal to the third blue tone value (B) and the third red tone value (R) is less than or equal to the third green tone value (G). If the third red gradation value (R) is smaller than or equal to the third blue gradation value (B), the blue content of the input image data (IMG) is already high, so the dog filter 500 decides that the first blue gradation value (B) will remain as the second blue gradation value (B').

[0126] Figure 15 is a conceptual diagram showing a dog filter 500 of a dog display device according to an embodiment of the present invention. The graph on the left of Figure 15 shows the human color coordinates for input image data (IMG), and the two graphs on the right show the human color coordinates and the dog color coordinates for dog image data (DIMG), respectively.

[0127] The dog display device according to this embodiment is the same as the dog display device shown in Figure 12, except for the process of generating dog image data (DIMG). Therefore, the same reference numerals are used for identical or similar components, and redundant explanations are omitted.

[0128] As shown in Figures 1b and 15, the dog filter 500 determines the second blue tone value (B') by adding the first blue tone value (B) and the correction value if the third red tone value (R) is greater than the third blue tone value (B) and the third green tone value (G) is greater than the third blue tone value (B). If the third red tone value (R) is greater than the third blue tone value (B) and the third green tone value (G) is less than or equal to the third blue tone value (B), the first blue tone value (B) is set to the second blue tone value. If the third red gradation value (R) is set as (B'), and the third blue gradation value (R) is smaller than or equal to the third blue gradation value (B), and the third green gradation value (G) is larger than the third blue gradation value (B), then the first blue gradation value (B) is set as the second blue gradation value (B'). If the third red gradation value (R) is smaller than or equal to the third blue gradation value (B), and the third green gradation value (G) is smaller than or equal to the third blue gradation value (B), then the first blue gradation value (B) is set as the second blue gradation value (B'). The correction value is larger the greater the difference between the third red gradation value (R) and the third blue gradation value (B).

[0129] The Dog Filter 500 determines the second blue tone value (B') by adding the first blue tone value (B) and the correction value if the third red tone value (R) is greater than the third blue tone value (B) and the third green tone value (G) is greater than the third blue tone value (B). Therefore, if the third red tone value (R) is greater than the third blue tone value (B) and the third green tone value (G) is greater than the third blue tone value (B), the second blue tone value (B') is greater than the first blue tone value (B). In other words, the Dog Filter 500 converts the input image data (IMG) into dog image data (DIMG) with a high blue content.

[0130] In one embodiment, the correction value is larger the greater the difference between the third red gradation value (R) and the third blue gradation value (B). The greater the difference between the third red gradation value (R) and the third blue gradation value (B), the lower the blue content of the input image data (IMG). Therefore, the correction value is larger the greater the difference between the third red gradation value (R) and the third blue gradation value (B).

[0131] In one embodiment, the correction value is larger the greater the difference between the third green tone value (G) and the third blue tone value (B). The greater the difference between the third green tone value (G) and the third blue tone value (B), the lower the blue content of the input image data (IMG). Therefore, the correction value is larger the greater the difference between the third green tone value (G) and the third blue tone value (B).

[0132] In one embodiment, the correction value is larger the larger the sum of the difference between the third red gradation value (R) and the third blue gradation value (B), and the difference between the third green gradation value (G) and the third blue gradation value (B). The larger the difference between the third red gradation value (R) and the third blue gradation value (B), and the larger the difference between the third green gradation value (G) and the third blue gradation value (B), the lower the blue content of the input image data (IMG). Therefore, the correction value is larger the larger the difference between the third green gradation value (G) and the third blue gradation value (B).

[0133] The Dog Filter 500 determines the first blue tone value (B) as the second blue tone value (B') if the third red tone value (R) is greater than the third blue tone value (B) and the third green tone value (G) is less than or equal to the third blue tone value (B). It also determines the first blue tone value (B) as the second blue tone value (B') if the third red tone value (R) is less than or equal to the third blue tone value (B) and the third green tone value (G) is greater than the third blue tone value (B). Finally, it determines the first blue tone value (B) as the second blue tone value (B') if the third red tone value (R) is less than or equal to the third blue tone value (B) and the third green tone value (G) is less than or equal to the third blue tone value (B). Since dogs perceive red and green as yellow, and blue as blue, if either the third red gradation value (R) or the third green gradation value (G) is smaller than or equal to the first blue gradation value, the blue content of the input image data (IMG) is already high. Therefore, the dog filter 500 simply sets the first blue gradation value (B) as the second blue gradation value (B').

[0134] Figure 16 is a conceptual diagram showing a dog filter 500 of a dog display device according to an embodiment of the present invention. The graph on the left of Figure 16 shows the human color coordinates for input image data (IMG), and the two graphs on the right show the human color coordinates and the dog color coordinates for dog image data (DIMG), respectively.

[0135] The dog display device according to this embodiment is the same as the dog display device shown in Figure 12, except for the process of generating dog image data (DIMG). Therefore, the same reference numerals are used for identical or similar components, and redundant explanations are omitted.

[0136] As shown in Figures 1b and 16, the dog filter 500 determines the second blue tone value (B') by adding the first blue tone value (B) and the correction value when the third green tone value (G") is greater than 0, and when the third green tone value (G") is 0, it determines the second blue tone value (B') by setting the first blue tone value (B) to the second blue tone value (B'). The correction value increases as the third green tone value (G") increases. For example, the correction value is greater than 0.

[0137] The Dog Filter 500 determines the second blue tone value (B') by adding the first blue tone value (B) and the correction value if the third green tone value (G) is greater than 0. Therefore, if the third green tone value (G) is greater than 0, the second blue tone value (B') is greater than the first blue tone value (B). In other words, the Dog Filter 500 converts the input image data (IMG) into dog image data (DIMG) with a high blue content.

[0138] The correction value increases as the third green tone value (G) increases. The larger the third green tone value (G) is, the lower the blue content of the input image data (IMG). Therefore, the correction value increases as the third green tone value (G) increases.

[0139] The dog filter 500 determines the first blue tone value (B) as the second blue tone value (B') if the third green tone value (G") is 0. If the third green tone value (G") is 0, the blue content of the input image data (IMG) is already high, so the dog filter 500 simply determines the first blue tone value (B) as the second blue tone value (B').

[0140] Figure 17 is a conceptual diagram showing a dog filter 500 of a dog display device according to an embodiment of the present invention. The graph on the left of Figure 17 shows the human color coordinates for input image data (IMG), and the two graphs on the right show the human color coordinates and the dog color coordinates for dog image data (DIMG), respectively.

[0141] The dog display device according to this embodiment is the same as the dog display device shown in Figure 16, except for the process of generating dog image data (DIMG). Therefore, the same reference numerals are used for identical or similar components, and redundant explanations are omitted.

[0142] As shown in Figures 1b and 17, the dog filter 500 determines the second blue tone value (B') by adding the first blue tone value (B) and the correction value if the third green tone value (G) is greater than the third blue tone value (B). If the third green tone value (G) is less than or equal to the third blue tone value (B), the first blue tone value (B) is set as the second blue tone value (B'). The correction value is larger the greater the difference between the third green tone value (G) and the third blue tone value (B).

[0143] The Dog Filter 500 determines the second blue tone value (B') by adding the first blue tone value (B) and the correction value if the third green tone value (G) is greater than the third blue tone value (B). Therefore, if the third green tone value (G) is greater than the third blue tone value (B), the second blue tone value (B') is greater than the first blue tone value (B). In other words, the Dog Filter 500 converts the input image data (IMG) into dog image data (DIMG) with a high blue content.

[0144] The correction value increases as the difference between the third green tone value (G) and the third blue tone value (B) increases. The larger the difference between the third green tone value (G) and the third blue tone value (B), the lower the blue content of the input image data (IMG). Therefore, the correction value increases as the difference between the third green tone value (G) and the third blue tone value (B) increases.

[0145] The dog filter 500 determines the first blue tone value (B) as the second blue tone value (B') if the third green tone value (G) is less than or equal to the third blue tone value (B). If the third green tone value (G) is less than or equal to the third blue tone value (B), the blue ratio of the input image data (IMG) is already high, so the dog filter 500 determines the first blue tone value (B) as the second blue tone value (B').

[0146] Figure 18 is a conceptual diagram showing a dog filter 500 of a dog display device according to an embodiment of the present invention. The graph on the left of Figure 18 shows the human color coordinates for input image data (IMG), and the two graphs on the right show the human color coordinates and the dog color coordinates for dog image data (DIMG), respectively.

[0147] The dog display device according to this embodiment is the same as the dog display device shown in Figure 16, except for the process of generating dog image data (DIMG). Therefore, the same reference numerals are used for identical or similar components, and redundant explanations are omitted.

[0148] As shown in Figures 1b and 18, the dog filter 500 determines the second blue tone value (B') by adding the first blue tone value (B) and the correction value if the third green tone value (G) is greater than the third blue tone value (B) and the third green tone value (G) is greater than the third red tone value (R). If the third green tone value (G) is greater than the third blue tone value (B) and the third green tone value (G) is less than or equal to the third red tone value (R), the first blue tone value (B) is set to the second blue tone value. If the first blue tone value (B) is set as (B'), and the third green tone value (G) is smaller than or equal to the third blue tone value (B), and the third green tone value (G) is larger than the third red tone value (R), then the first blue tone value (B) is set as the second blue tone value (B'). If the third green tone value (G) is smaller than or equal to the third blue tone value (B), and the third green tone value (G) is smaller than or equal to the third red tone value (R), then the first blue tone value (B) is set as the second blue tone value (B'). The correction value is larger the greater the difference between the third green tone value (G) and the third blue tone value (B).

[0149] The Dog Filter 500 determines the second blue tone value (B') by adding the first blue tone value (B) and the correction value if the third green tone value (G) is greater than the third blue tone value (B) and the third green tone value (G) is greater than the third red tone value (R). Therefore, if the third green tone value (G) is greater than the third blue tone value (B) and the third green tone value (G) is greater than the third red tone value (R), the second blue tone value (B') is greater than the first blue tone value (B). In other words, the Dog Filter 500 converts the input image data (IMG) into dog image data (DIMG) with a high blue content.

[0150] The correction value increases as the difference between the third green tone value (G) and the third blue tone value (B) increases. The larger the difference between the third green tone value (G) and the third blue tone value (B), the lower the blue content of the input image data (IMG). Therefore, the correction value increases as the difference between the third green tone value (G) and the third blue tone value (B) increases.

[0151] The Dog Filter 500 determines the first blue tone value (B) as the second blue tone value (B') if the third green tone value (G) is greater than the third blue tone value (B) and the third green tone value (G) is less than or equal to the third red tone value (R); the first blue tone value (B) as the second blue tone value (B') if the third green tone value (G) is less than or equal to the third blue tone value (B) and the third green tone value (G) is greater than the third red tone value (R); and the first blue tone value (B) as the second blue tone value (B') if the third green tone value (G) is less than or equal to the third blue tone value (B) and the third green tone value (G) is less than or equal to the third red tone value (R). If the third green tone value (G) is less than or equal to the third blue tone value (B), the blue content of the input image data (IMG) is already high, so the dog filter 500 decides that the first blue tone value (B) will remain as the second blue tone value (B').

[0152] Figures 19a, 20a, 21a, and 22-26 are conceptual diagrams showing the dog filter 500 of a dog display device according to an embodiment of the present invention. Figure 19b shows an example of color change due to the dog filter 500 in Figure 19a, Figure 20b shows an example of color change due to the dog filter 500 in Figure 20a, Figure 21b shows an example of color change due to the dog filter 500 in Figure 21a, and Figure 27 shows the color coordinates of the dog display device in Figures 19a-26. The left-hand graphs in Figures 19b, 20b, and 21b show the human color coordinates for input image data (IMG), while the two right-hand graphs show the human color coordinates and dog color coordinates for dog image data (DIMG), respectively.

[0153] The dog display device according to this embodiment is similar in configuration to the dog display devices in Figures 1b, 5a, 6a, 7a, and 12 to 15 (corresponding to Figures 19a, 20a, 21a, and 22 to 26), except that instead of adding the first blue gradation value (B) and the correction value, the correction value is subtracted from the first red gradation value (R). Therefore, the same reference numerals are used for identical or similar components, and redundant explanations are omitted.

[0154] As shown in Figures 1b and 19a through 27, the dog filter 500 determines the second red tone value (R') of the dog image data (DIMG) relative to the red image data by subtracting a correction value from the first red tone value (R). For example, the correction value is greater than 0. When the second red tone value (R') is determined by subtracting the correction value from the first red tone value (R), the second red tone value (R') is smaller than the first red tone value (R). Therefore, the dog filter 500 converts the input image data (IMG) into dog image data (DIMG) with a higher blue tone by reducing the yellow tone (i.e., because dogs perceive red and green as yellow).

[0155] As shown in Figures 2 and 27, the color space in Figure 27 indicates that the second color space (CS2) in Figure 2 has been converted. In the converted color spaces of the dog display devices in Figures 19a to 26, the coordinates of the red color (rightmost vertex of the triangle) are transformed compared to the second color space (CS2).

[0156] Figures 28a, 29a, and 30a are conceptual diagrams showing a dog filter 500 of another dog display device in an embodiment of the present invention; Figure 28b shows an example of color change by the dog filter 500 of Figure 28a; Figure 29b shows an example of color change by the dog filter 500 of Figure 29a; and Figure 30b shows an example of color change by the dog filter 500 of Figure 30a. The left-hand graphs in Figures 28b, 29b, and 30b show human color coordinates for input image data (IMG), and the two right-hand graphs show human color coordinates and dog color coordinates for dog image data (DIMG), respectively.

[0157] The dog display device according to this embodiment is similar in configuration to the dog display devices in Figures 8a, 9a, and 10a (corresponding to Figures 28a, 29a, and 30a), except that instead of adding the first blue gradation value (B) and the correction value, the correction value is subtracted from the first green gradation value (G). Therefore, the same reference numerals are used for identical or similar components, and redundant explanations are omitted.

[0158] As shown in Figures 1b and 28a to 30b, the dog filter 500 determines the second green tone value (R') of the dog image data (DIMG) relative to the green image data by subtracting a correction value from the first green tone value (G). For example, the correction value is greater than 0. If the second red tone value (R') is determined by subtracting the correction value from the first red tone value (R), then the second red tone value (R') is smaller than the first red tone value (R). Therefore, the dog filter 500 converts the input image data (IMG) into dog image data (DIMG) with a higher blue tone by reducing the green tone (i.e., because dogs perceive red and green as yellow).

[0159] Figure 31 is a conceptual diagram showing a dog filter 500 of a dog display device according to an embodiment of the present invention. The graph on the left of Figure 31 shows the human color coordinates for input image data (IMG), and the two graphs on the right show the human color coordinates and the dog color coordinates for dog image data (DIMG), respectively.

[0160] The dog display device according to this embodiment is similar in configuration to the dog display device in Figure 7a, except that instead of adding the first blue gradation value (B) and the correction value, the correction value is subtracted from the first green gradation value (G). Therefore, the same reference numerals are used for identical or similar components, and redundant explanations are omitted.

[0161] As shown in Figures 1b and 31, the dog filter 500 determines the second green tone value (R') by subtracting a correction value from the first green tone value (G). For example, the correction value is greater than 0. If the second red tone value (R') is determined by subtracting the correction value from the first red tone value (R), then the second red tone value (R') is smaller than the first red tone value (R). Therefore, the dog filter 500 converts the input image data (IMG) into dog image data (DIMG) with a higher blue tone ratio by reducing the green tone ratio (i.e., because dogs perceive red and green as yellow).

[0162] Figures 32 to 34 are conceptual diagrams showing a dog filter 500 of a dog display device according to an embodiment of the present invention. The left graph in Figures 32 to 34 shows the human color coordinates for input image data (IMG), and the two graphs on the right show the human color coordinates and the dog color coordinates for dog image data (DIMG), respectively.

[0163] The dog display device according to this embodiment is similar in configuration to the dog display devices in Figures 16 to 18 (corresponding to Figures 32 to 34), except that instead of adding the first blue gradation value (B) and the correction value, the correction value is subtracted from the first green gradation value (G). Therefore, the same reference numerals are used for identical or similar components, and redundant explanations are omitted.

[0164] As shown in Figures 1b and 32 to 34, the dog filter 500 determines the second green tone value (R') by subtracting a correction value from the first green tone value (G). For example, the correction value is greater than 0. If the second red tone value (R') is determined by subtracting the correction value from the first red tone value (R), then the second red tone value (R') is smaller than the first red tone value (R). Therefore, the dog filter 500 converts the input image data (IMG) into dog image data (DIMG) with a high blue tone ratio by reducing the green tone ratio (i.e., because dogs perceive red and green as yellow).

[0165] Figure 35 is a conceptual diagram showing a dog filter 500 of a dog display device according to an embodiment of the present invention. The graph on the left of Figure 35 shows the human color coordinates for input image data (IMG), and the two graphs on the right show the human color coordinates and the dog color coordinates for dog image data (DIMG), respectively.

[0166] The dog display device according to this embodiment is similar in configuration to the dog display device in Figure 15, except that instead of adding the first blue gradation value (B) and the correction value, the correction value is subtracted from the first green gradation value (G). Therefore, the same reference numerals are used for identical or similar components, and redundant explanations are omitted.

[0167] As shown in Figures 1b and 35, the dog filter 500 determines the second green tone value (G') by subtracting a correction value from the first green tone value (G). For example, the correction value is greater than 0. If the second red tone value (R') is determined by subtracting the correction value from the first red tone value (R), then the second red tone value (R') is smaller than the first red tone value (R). Therefore, the dog filter 500 converts the input image data (IMG) into dog image data (DIMG) with a higher blue tone ratio by reducing the green tone ratio (i.e., because dogs perceive red and green as yellow).

[0168] Figure 36 shows the color coordinates of the dog display devices shown in Figures 28a to 35. As shown in Figures 2 and 36, the color space in Figure 36 indicates that the second color space (CS2) in Figure 2 has been converted. In the converted color spaces of the dog display devices in Figures 28a to 35, the coordinates of green (the upper vertex of the triangle) are converted compared to the second color space (CS2). Figure 37 shows the color values ​​(H_IMG, H_DIMG) of the input image data (IMG) and dog data (DIMG) of the dog display device according to an embodiment of the present invention.

[0169] The dog display device according to this embodiment is the same as the dog display device 1000 in Figure 1b, except for the dog filter 500. Therefore, the same reference numerals are used for identical or similar components, and redundant explanations are omitted.

[0170] As shown in Figures 1b and 37, the dog filter 500 generates dog image data (DIMG) by increasing the blue content of the input image data (IMG). For example, the dog filter 500 converts RGB domain input image data (IMG) to HSV domain input image data, expands the blue interval (P1) of the color values ​​(H_IMG) of the HSV domain input image data, shrinks the red interval (P2) of the color values ​​(H_IMG) of the HSV domain input image data, generates HSV domain dog image data, and then generates RGB domain dog image data (DIMG) based on the HSV domain dog image data. In another embodiment, the dog filter 500 expands the blue interval (P1) and shrinks the green interval of the color values ​​(H_IMG) of the HSV domain input image data to generate HSV domain dog image data.

[0171] For example, the color values ​​in the HSV domain range from 0° to 360°. The 240° to 300° range represents the blue range (P1), and the 300° to 360° and 0° to 30° ranges represent the red range (P2). The dog filter 500 expands the blue range (P1) to 240° to 360° and shrinks the red range (P2) to 0° to 30°. Therefore, the color of the image displayed based on input image data with a color value (H_IMG) of 300° is the same as the color of the image displayed based on dog image data with a color value (H_DIMG) of 360°. For example, the color of the image displayed based on input image data with a color value (H_IMG) of 270° is the same as the color of the image displayed based on dog image data with a color value (H_DIMG) of 300°. Therefore, the blue percentage of the dog image data (DIMG) is higher than the blue percentage of the input image data (IMG).

[0172] Figure 38 shows the color-specific brightness levels of a dog display device according to an embodiment of the present invention. The dog display device according to this embodiment has the same configuration as the dog display device 1000 in Figure 1b, except for the dog filter 500. Therefore, the same reference numerals are used for identical or similar components, and redundant explanations are omitted.

[0173] As shown in Figures 1b and 38, the dog filter 500 increases the difference in brightness between the red region (RG) and the green region (GG) of the input image data (IMG) to generate dog image data (DIMG).

[0174] For example, the dog filter 500 converts input image data (IMG) in the RGB domain to the luminance domain, and then converts the luminance of the input image data in the luminance domain to generate dog image data (DIMG). For example, it decreases the luminance of the red region (RG) and increases the luminance of the green region (GG) of the input image data (IMG). For example, the dog filter 500 further decreases the luminance of the red region (RG) as it moves away from yellow, and further increases the luminance of the green region (GG) as it moves away from yellow. As a result, the red image and the green image can be distinguished by the difference in luminance. Therefore, even a dog that cannot distinguish between red and green well can distinguish between the red image and the green image. [Industrial applicability]

[0175] The present invention is applicable to dog display devices and electronic devices including the same. For example, the present invention can be applied to digital TVs, 3D TVs, mobile phones, smartphones, tablet computers, VR devices, PCs, home electronic devices, notebook computers, PDAs, PMPs, digital cameras, music players, portable game consoles, navigation systems, and the like.
