[Figure 9] 2 is a flowchart of the operation of the display control unit shown in FIG. DETAILED DESCRIPTION OF THE INVENTION

[0017] A display control device according to one embodiment of the present invention will be described below. In the display control device according to one embodiment of the present invention, an acquisition unit acquires a representative color from image data associated with playback data, and a display control unit displays a color based on the representative color on a display unit other than the display unit that displays the image data. In this way, colors based on the image data can be displayed on a display unit other than the display unit, thereby achieving color harmony between the image data and its surroundings.

[0018] In addition, there may be a plurality of representative colors, which allows for color harmony to be achieved using a plurality of colors based on image data.

[0019] The display control unit may also cause the luminous colors of the controls provided around the display unit to be emitted in colors based on the representative color, thereby achieving color harmony by causing the controls, such as physical keys including operation buttons provided around the display unit, to emit light in colors based on the image data.

[0020] The display control unit may also display a color based on the representative color in at least a partial area of ​​another display unit different from the display unit, thereby achieving color harmony by causing a display unit such as a display provided separately from the display configured as the display unit to emit light in a color based on image data.

[0021] The present invention may further include a processing unit that processes the representative color to enhance its visibility. By doing so, even if the representative color has low visibility, it is possible to achieve color harmony while enhancing its visibility.

[0022] Furthermore, if the acquired representative color is an achromatic color, the processing unit may process it into a chromatic color. By doing so, if an achromatic color such as white, black, or gray is acquired as the representative color, a color can be added. If the achromatic color is displayed as is, for example, push buttons, icons, etc. may become unrecognizable or may give the impression that they are inoperable, so adding a color can prevent this from being misleading. Furthermore, the processing unit may convert the acquired representative color to match the light-emitting capability (i.e., the color that can be expressed) of the object to be illuminated. By doing so, an appropriate color can be selected according to the light-emitting capability of the object to be illuminated.

[0023] In addition, in a display control device according to another embodiment of the present invention, an acquisition unit acquires a representative color from image data associated with playback data, and a processing unit processes the representative color and displays it in an area of ​​the display unit separate from the area where the image data is displayed. In this way, the visibility of the color based on the image data can be improved and it can be displayed in an area other than the area where the image data is displayed, and color harmony between the image data and its surroundings can be achieved within the display unit.

[0024] In addition, in a display control method according to one embodiment of the present invention, the acquisition step acquires a representative color from image data associated with the playback data, and the display control step displays a color based on the representative color on a display unit other than the display unit that displays the image data. In this way, the color based on the image data can be displayed on a display unit other than the display unit, thereby achieving color harmony between the image data and its surroundings.

[0025] Furthermore, the above-described display control method is executed by a computer, which allows the computer to display colors based on image data on devices other than the display unit, thereby achieving color harmony between the image data and the surroundings.

[0026] The display control program may be stored in a computer-readable storage medium, which allows the program to be distributed as a standalone program rather than being incorporated into a device, and allows for easy version upgrades.

[0027] In addition, in a display control method according to another embodiment of the present invention, the acquisition step acquires a representative color from image data associated with the playback data, and the processing unit processes the representative color and displays it in an area of ​​the display unit separate from the area where the image data is displayed. In this way, the visibility of the color based on the image data can be improved and it can be displayed in an area other than the area where the image data is displayed, and color harmony between the image data and its surroundings can be achieved within the display unit.

[0028] Furthermore, the above-described display control method is executed by a computer, which allows the computer to display colors based on image data in areas other than the area where the image data is displayed, thereby achieving color harmony between the image data and its surroundings.

[0029] The display control program may be stored in a computer-readable storage medium, which allows the program to be distributed as a standalone program rather than being incorporated into a device, and allows for easy version upgrades. [Example]

[0030] A display control device according to an embodiment of the present invention will be described with reference to Figures 1 to 9. A navigation device 1 as a display control device according to this embodiment is installed in a mobile body such as an automobile. Although the present embodiment will be described using a navigation device 1, the present invention may be applied to other in-vehicle devices such as car audio or display audio, or to devices such as a portable device that has a display unit and components capable of displaying or emitting light other than a display unit that displays image data such as a jacket image.

[0031] As shown in FIG. 1, the navigation device 1 includes a storage unit 2, a playback unit 3, a display control unit 4, a display unit 5, push buttons 6, and an output interface (I / F) 7.

[0032] The storage unit 2 is configured, for example, with a non-volatile semiconductor memory, a hard disk drive, or the like. The storage unit 2 stores music data 2a. The music data 2a is configured in a format that allows music data to include image data, such as MP3 (MPEG-1 Audio Layer-3). However, the music data 2a does not have to include image data, as long as the music data 2a and image data are associated with each other. Note that this association does not have to be done in advance, and may be performed, for example, by a process of searching for images related to the music during playback.

[0033] The playback unit 3 reads out the music data 2a stored in the storage unit 2, plays back the audio data from the music data 2a, and outputs it to the amplifier 11. The playback unit 3 also outputs the image data from the read music data 2a to the display control unit 4.

[0034] The display control unit 4 displays the image data output from the playback unit 3 on the display unit 5. The display control unit 4 also extracts a representative color from the image data, processes it to improve visibility, and outputs it to the push button 6 or the output I / F 7. The display control unit 4 includes an image data acquisition unit 4a, a color extraction unit 4b, and a processing unit 4c.

[0035] The image data acquisition unit 4a acquires the image data output from the playback unit 3. The image data acquisition unit 4a also causes the display unit 5 to display the acquired image data.

[0036] The color extraction unit 4b extracts (acquires) representative colors from the image data acquired by the image data acquisition unit 4a. The representative colors refer to the colors that rank highest among the colors constituting the image data, ranked according to a predetermined criterion. For example, the representative colors can be ranked based on the dominant color in the image data, the most vivid, the brightest, or the warmest. In this embodiment, two types of colors can be extracted as representative colors: a main color and a sub-color. The main color is the color that ranks highest in the image data, as described above, and the sub-color is the color that ranks next to the main color. Various combinations are possible, such as selecting a dominant color and a most vivid color. The color extraction unit 4b may extract only the main color, or may extract two or more sub-colors. The color extraction method may be any known method, and is not particularly limited. Although the display control unit 4 includes the color extraction unit 4b in this embodiment, the display control unit 4 may also acquire information about colors extracted externally.

[0037] The processing unit 4c processes the colors extracted by the color extraction unit 4b to enhance their visibility. In other words, the colors processed by the processing unit 4c are based on the representative color. In this embodiment, 30 chromatic colors and two achromatic colors are predefined. These colors have a certain brightness level or higher to ensure visibility regardless of the background color of the display unit 5. The chromatic colors are divided into 30 hues and then the RGB values ​​of each color are adjusted to ensure color differences on their own and to ensure natural overlap when selected as the main color and sub color. Note that 30 colors are just an example, and the number of colors may be changed as appropriate. The processing unit 4c may also convert the extracted full-color RGB into 112 custom-defined colors to match the light-emitting capabilities (i.e., the colors that can be expressed) of the target to be illuminated.

[0038] The achromatic color is used when the extracted color is achromatic (white, black, etc.). In this embodiment, all grayscales are uniformly approximated to one of two colors. Therefore, using the intermediate gray of the grayscale (gray with an RGB value intermediate between black and white) as the reference, two colors are set: one intermediate between the reference gray and black, and one intermediate between the reference gray and white. Note that two colors are just an example, and one color or three or more colors may be used. These two colors are used in places where functions or states are expressed by color, and in places other than places where functions or states are expressed by color.

[0039] When used in areas where functions or states are expressed by color, displaying it in grayscale may give users a false impression, so it is converted to a chromatic color. For example, if the theme color of the GUI displayed on the display unit 5 is blue, it is processed into two colors, dark blue and light blue. On the other hand, when it is used in areas other than areas where functions or states are expressed by color, it is adjusted to a color that does not blend in with surrounding drawings or backgrounds, taking visibility into consideration. For example, it is processed into two colors, dark gray and light gray.

[0040] In this embodiment, processing by the processing unit 4c is essential, but processing does not have to be performed. In other words, the extracted color may be displayed as it is.

[0041] The display unit 5 is configured with, for example, a liquid crystal display. The display unit 5 displays image data output from the display control unit 4. In this embodiment, the image data is not necessarily displayed on the entire screen of the display unit 5, but may also be displayed in a part of the display area of ​​the display unit 5 together with the title of the song, the name of the artist, or icons such as operation button images.

[0042] An example of a screen displayed on the display unit 5 will now be described with reference to Fig. 2. The example of the screen shown in Fig. 2 includes a jacket image 51, a main color display area 52, a sub-color display area 53, a spotlight-like display area 54, a text information display area 55, a play / pause button 56, a previous song button 57, a next song button 58, and a playback position slider 59.

[0043] The jacket image 51 is image data included in the music data 2a described above. Although the jacket image 51 is shown in FIG. 2, it may be a photograph of the artist or the like. The main color display area 52 is an area where the main color processed by the processing unit 4c is displayed. The main color display area 52 is hexagonal in FIG. 2, but may be another shape. The sub-color display area 53 is an area where the sub-color processed by the processing unit 4c is displayed. The shape of the sub-color display area 53 is not limited to that shown in FIG. 2.

[0044] The spotlight-shaped display area 54 is an area where the main color and sub-color are displayed, and the colors are displayed as if illuminated by a spotlight. The spotlight-shaped display area 54 is not limited to displaying only the main color or the sub-color, but may also display both mixedly or in separate areas. The main color display area 52, the sub-color display area 53, and the spotlight-shaped display area 54 are examples of areas separate from the area where image data on the display unit 5 is displayed.

[0045] The text information display area 55 displays text information such as song titles and artist names. The play / pause button 56 is a button icon for playing and pausing songs. The previous song button 57 is a button icon for returning to the song before the song currently being played. The next song button 58 is a button icon for returning to the song after the song currently being played. The playback position slider 59 indicates the playback position of the song currently being played. The playback position slider 59 can also be operated to play from any position in the song currently being played.

[0046] The text information display area 55, play / pause button 56, previous song button 57, next song button 58, and playback position slider 59 may also be colored with a main color or a sub color. When coloring components that indicate functions or states, such as the text information display area 55, play / pause button 56, previous song button 57, next song button 58, and playback position slider 59, if the extracted color is achromatic, the achromatic color is changed to a chromatic color as described above.

[0047] The push button 6 is a mechanical operation button (operator) that is operated by pressing it with a finger, etc. The part of the push button 6 that is pressed is made to transmit light, and three color LEDs (light emitting diodes) of red, green, and blue (RGB) are provided inside the push button 6, and by adjusting the brightness of each color, it is possible to emit light in various colors.

[0048] An example of the placement of the push buttons 6 will be described with reference to Fig. 3. Fig. 3 shows a front view of the navigation device 1. In the example of Fig. 3, multiple (four) push buttons 6 are provided below the display unit 5. In Fig. 3, each push button 6 is individually provided with an LED of three colors, so that each push button can emit light of a different color.

[0049] The output I / F 7 outputs color (main color, sub color) information processed by the display control unit 4 to an external display device (a display unit other than the display unit 5) described later. The output I / F 7 converts the information into a signal based on, for example, a CAN (Controller Area Network) and can be configured as a wired or wireless connection. The image is output to an external display device or the like via a network.

[0050] The amplifier 11 amplifies the signal representing the audio data output from the playback unit 3. The speaker 12 outputs the signal amplified by the amplifier 11 as sound.

[0051] The meter 21 is an example of an external display device and is an instrument that displays information such as the speed of a vehicle or the like. The meter 21 is capable of changing its display color based on color information output from the navigation device 1. The air conditioner 22 is an example of an external display device and adjusts the temperature inside the vehicle. The air conditioner 22 is capable of changing the light emission color of buttons for temperature control, etc., and the display color of the display unit for the set temperature, etc., based on color information output from the navigation device 1. The lighting 23 is an example of an external display device and is lighting provided inside the vehicle. This lighting may be for brightening the vehicle interior to make it easier to see, or may be for decorative purposes. The lighting 23 is capable of changing its light emission color based on color information output from the navigation device 1.

[0052] In addition to the above-described configuration, the navigation device 1 also has map data and a well-known function of guiding to a destination based on the map data and a current position detected by a GPS (Global Positioning System) or the like, but a description of this function will be omitted in this embodiment.

[0053] Next, examples of illumination of the push buttons 6 in the navigation device 1 configured as described above will be described with reference to Figs. 4 and 5. Fig. 4 shows an example in which all of the push buttons 6 are illuminated in a processed main color. By illuminating the push buttons 6 in a processed main color, color harmony can be achieved throughout the navigation device 1. Note that in the example of Fig. 4, illumination is not limited to the processed main color, and the buttons may also be illuminated in a processed sub-color.

[0054] FIG. 5 shows an example in which the two push buttons 6 on the right illuminate in a processed main color, and the two push buttons 6 on the left illuminate in a processed sub-color. By illuminating in two colors as in FIG. 5, it is possible to achieve better color harmony throughout the navigation device 1. In particular, if the push button 6 that illuminates in the processed main color is closest to the jacket image 51, better color harmony can be achieved. Note that in the examples of FIGS. 4 and 5, all of the push buttons 6 are illuminated in the main color or sub-color, but it is also possible to illuminate only some of the push buttons 6 in the main color or sub-color.

[0055] Next, examples of display (illumination) using color information on the meter 21, the air conditioner 22, and the lighting 23 will be described with reference to Fig. 6 to Fig. 8. First, an example of display using color information on the meter 21 will be described with reference to Fig. 6.

[0056] Fig. 5 shows an example of the meter 21. The meter 21 is a vehicle meter, and as shown in Fig. 5, a display 21a serving as a display means is disposed in the center of the front of the meter 21. A speedometer 21b serving as an analog indicating instrument is disposed to the right of the display 21a, and a tachometer 21c serving as an analog indicating instrument is disposed to the left of the display 21a.

[0057] The display 21a may be configured as a liquid crystal display, and displays an odometer / trip meter, a fuel gauge, various warnings, and the like.

[0058] In the meter 21 configured as described above, for example, the illumination of the speedometer 21b and tachometer 21c (or the display colors of the numerals, pointers, scales, etc.) is illuminated based on color information. In recent years, in order to change the luminous color of these meters in accordance with the driving conditions, the driver's preferences, etc., many meters have LEDs of the three primary colors (RGB) in the light-emitting portions of the speedometer 21b and tachometer 21c, similar to the push buttons 6. In this embodiment, the speedometer 21b and tachometer 21c are also displayed based on color information, thereby achieving color harmony with the jacket image 51. In addition, the background color, etc., of the display 21a can also be displayed based on color information. In another example, the entire panel of the meter 21 may be formed by a liquid crystal display or the like, and the speedometer and tachometer may be displayed on the screen, and the display colors of the components of the speedometer and tachometer may be controlled based on color information.

[0059] Next, an example of displaying (illuminating) the luminous color of buttons for temperature adjustment and the display color of the set temperature display of the air conditioner 22 using color information will be described with reference to Fig. 7. Fig. 7 shows an example of the operating parts of the air conditioner 22. The air conditioner 22 has various switches and the like for operating the air conditioner installed on the instrument panel.

[0060] In the example of Figure 6, various switches and the like for operating the air conditioner are provided, such as an LCD display 22a, an inside / outside air selector switch 22b, a front defroster switch 22c, a rear defroster switch 22d, a DUAL switch 22e, a mode selector switch 22f, a blower air volume selector switch 22g, an A / C switch 22h, an AUTO switch 22i, an OFF switch 22j, a driver's seat temperature setting switch 22k, and a passenger's seat temperature setting switch 22l.

[0061] Of the above-mentioned switches, the liquid crystal display 22a can display the background color and the like using color information, similar to the display 21a of the meter 21. Furthermore, the inside / outside air selector switch 22b, the front defroster switch 22c, the rear defroster switch 22d, the DUAL switch 22e, the mode selector switch 22f, the blower air volume selector switch 22g, the A / C switch 22h, the AUTO switch 22i, the OFF switch 22j, the driver's seat temperature setting switch 22k, and the passenger's seat temperature setting switch 22l can emit light in a color that is based on color information, similar to the push button 6. Therefore, the color of the air conditioner 22 can also be harmonized with the jacket image 51.

[0062] Next, an example of changing the emission color of the light 23 based on color information will be described with reference to Fig. 8. Fig. 8 is a perspective view showing the interior of a vehicle (mobile body). An instrument panel 101 and a center console 102 are provided in the interior 100 of the vehicle. A door interior panel 103 is provided on the interior surface of the driver's door D. Of course, similar door interior panels are also provided on the other doors. A ceiling interior panel 104 is provided on the interior surface of the ceiling C.

[0063] The instrument panel 101 is disposed below the windshield glass W provided at the front of the vehicle, and has meters 21 and a steering wheel 107 provided in front of the driver's seat S1, and a navigation device 1 and an air conditioner 22 provided in the center between the driver's seat S1 and the passenger seat S2. A rear seat S3 is provided behind the driver's seat S1 and the passenger seat S2.

[0064] The center console 102 is a generally rectangular cylindrical portion whose one end is connected to the center of the instrument panel 101, passes between the driver's seat S1 and the passenger seat S2, and extends to the vicinity of the backrests of these seats. On the instrument panel 101 side of the center console 102, a shift lever S for switching the transmission of the automobile and the like are provided.

[0065] The door interior panel 103 is provided with a power window switch unit 105 for inputting opening and closing operations of the window glass provided in each door, the above-mentioned speaker 12, and the like.

[0066] A light 23 is provided in the approximate center of the ceiling interior panel 104. The light 23 is provided with a driver's seat side light emitting portion, a driver's seat side light emitting switch, a passenger's seat side light emitting portion, a passenger's seat side light emitting switch, and the like.

[0067] The light 23 can also emit light in a color determined by color information, similar to the push button 6. In other words, the light 23 emits light in a changeable color. Therefore, the light 23 can also be chromatically harmonized with the jacket image 51.

[0068] The lighting 23 is not limited to those (map lamps) provided on the ceiling interior panel 104. For example, decorative lighting fixtures provided on the instrument panel 101 or around the speakers 12 may be illuminated based on color information. In addition to the air conditioner 22, switches provided on the instrument panel 101 or the center console 102 may also be illuminated based on color information. Furthermore, the steering wheel 107 or the rear seat S3 may be provided with light-emitting units (display units) that can illuminate based on color information.

[0069] Next, the operation (display control method) of the navigation device 1 described above will be described with reference to the flowchart in Fig. 9. The flowchart shown in Fig. 9 is mainly executed by the display control unit 4. This flowchart can be configured as a program executed by the CPU of the display control unit 4, thereby forming a display control program. Furthermore, this display control program is not limited to being stored in a memory or the like of the display control unit 4, but may also be stored in a storage medium such as a memory card or optical disk.

[0070] First, in step S1, the playback unit 3 reads out the music data 2a to be played back. Then, in step S2, the image data acquisition unit 4a acquires image data included in the music data 2a that the playback unit 3 has read out.

[0071] Next, in step S3, the color extraction unit 4b extracts a main color and a sub-color, and in step S4, the processing unit 4c performs processing to enhance the visibility of the extracted main color and sub-color.

[0072] Next, in step S5, the display control unit 4 displays the image data on the display unit 5, and also displays the main color display area 52, sub-color display area 53, spotlight-like display area 54, etc. Furthermore, the display control unit 4 also displays and illuminates the meter 21, air conditioner 22, and lighting 23 via the push button 6 and the output I / F 7. Here, the timing of displaying the image data and the timing of displaying the main color and sub-color may be instructed simultaneously, or a time lag may be applied depending on the position of the display illumination. Instructing them simultaneously is effective in creating a sense of immersion in the space and music and prevents the color from being reflected before the image data is displayed. When a time lag is applied, for example, by switching from a light-emitting device at the front of the vehicle to a light-emitting device at a time lag toward the rear, it is possible to create a sense of integration with the movement of the vehicle.

[0073] When image data or the like is switched, the main color and sub color will naturally also be switched, but in this case, a natural transition can be achieved by gradually changing from the previous color to the next color over a period of, for example, about one second. This operation can also be timed to coincide with the crossfade of the music.

[0074] If the music data 2a does not include image data, a predetermined color may be displayed. This predetermined color may be changed when the music changes or at predetermined time intervals.

[0075] In the above-described embodiment, the processing unit 4c processes the colors displayed on all display units, but this is not limited to this. The processing unit may be common to each display unit, or a dedicated processing unit may be provided for each display unit. Furthermore, one processing unit may perform multiple processing processes optimized for each display unit. This allows optimal color processing to be performed for each display unit.

[0076] According to this embodiment, the display control unit 4 extracts a main color and a sub-color from image data included in the music data 2a using the color extraction unit 4b, and processes the main color and sub-color using the processing unit 4c, and displays or emits colors on the push buttons 6, meters 21, air conditioner 22, lights 23, etc. In this way, colors based on image data such as a jacket image can be displayed on devices other than the display unit 5, and color harmony between the image data such as a jacket image and its surroundings can be achieved.

[0077] In addition, the main color and sub-color are processed by the processing unit 4c to enhance their visibility. By doing so, even if the main color and sub-color have low visibility, it is possible to achieve color harmony while enhancing visibility.

[0078] Furthermore, if the acquired main color or sub-color is achromatic, the processing unit 4c processes it into a chromatic color. By doing so, if an achromatic color such as white, black, or gray is acquired, a color can be added. If the achromatic color is displayed as is, for example, push buttons or icons may become unrecognizable or may give the wrong impression that they are inoperable, so adding a color can prevent this from happening.

[0079] Furthermore, the display control unit 4 processes the main color and sub color using the processing unit 4c and displays them in a spotlight-like display area 54, which is a separate area from the area where the jacket image 51 is displayed on the display unit 5. In this way, the color based on the image data can be displayed in an area other than the area where the image data is displayed, and color harmony between the image data and its surroundings can be achieved within the display unit 5.

[0080] Furthermore, the display control unit 4 processes the main color and sub-color by the processing unit 4c on a display unit other than the display unit 5, such as the display 21a of the meter 21 or the liquid crystal display 22a of the air conditioner 22. In this way, color harmony can be achieved for display units other than the display unit 5. Furthermore, as a display unit other than the display unit 5, for example, the entire surface of the meter 21 may be configured as a liquid crystal display or the like, and the main color and sub-color may be displayed in the colors processed by the processing unit 4c for all or part of the liquid crystal display.

[0081] In the above-described embodiment, still images are used as image data, but moving images such as movies may also be used. By using moving images, it is possible to achieve color harmony with the surroundings of the display unit 5 using colors that match the scenes in the moving image. This can therefore enhance the sense of realism.

[0082] Also, the layout information of the display units to be light-emission controlled is registered in advance (for example, there are four buttons below the display unit that displays the jacket image, and there is a meter on the right side of the display unit). Then, along with extracting the colors, the distribution of colors on the jacket image (e.g., red is biased toward the upper right of the image) may be extracted, and the colors of some of the display units arranged horizontally or vertically, such as buttons below the screen, may be changed to match the color distribution on the jacket image. Also, for example, the color distribution on the image may be reproduced for the entire vehicle, with the front of the vehicle positioned at the top of the image, the rear at the bottom of the image, and the left and right sides of the vehicle positioned at the left and right sides of the image.

[0083] 1 is switched to a map display screen or the like, and even if a jacket image is not displayed, the light may continue to be emitted in a color based on the jacket image as long as the music corresponding to the jacket image is being played. This allows the user to recall the jacket image being played even when the image is not displayed on the screen, and maintain a sense of immersion in the music, etc.

[0084] Furthermore, the present invention is not limited to the above-described embodiments. In other words, a person skilled in the art can implement various modifications in accordance with conventionally known knowledge without departing from the gist of the present invention. As long as such modifications still include the display control device of the present invention, they are of course included in the scope of the present invention. [Explanation of symbols]
