Description

Technical Field

[0001] This invention relates to the technical field of display terminal scenarios, and in particular to a display improvement method, system, terminal, and storage medium based on total color blindness. Background Technology

[0002] Color weakness, also known as "abnormal trichromatic vision," allows the person to recognize colors but with low sensitivity, only able to distinguish hue changes when there are significant differences in wavelength. Color blindness, usually called congenital color vision deficiency, prevents the person from distinguishing all colors in the natural spectrum or a specific color. Achromatopsia is a complete dysfunction of cone cells, the opposite of night blindness (rod cell dysfunction). Patients with achromatopsia prefer darkness and are sensitive to light, exhibiting day blindness. The cone cells in the retina contain three photosensitive pigments that help identify the three primary colors: red, green, and blue. Figure 1 The spectrum of light is L (long wavelength), M (medium wavelength), and S (short wavelength). When the retina lacks a certain photosensitive pigment, a person who cannot distinguish one or more colors is medically termed colorblind. If they cannot perceive any of the three colors, they are considered totally colorblind. Tototal colorblind individuals perceive the colorful world as a gray expanse, like watching a black-and-white television; there is only a distinction between light and dark, but no color difference. The incidence of color weakness and color blindness in my country is approximately 5%–8% for men and 0.5%–1% for women. About 6% of the population has trichromatic vision (color weakness), about 2% has dichromatic vision (color blindness), and a portion has monochromatic vision (total colorblindness).

[0003] Existing technologies improve the visual experience of target groups by increasing the amount of target pixels (red, green, and blue pixels) on the display and calling target modes. Therefore, different displays need to be customized for different target groups, which is costly and inflexible. It has some effect on improving color weakness, but little effect on improving color blindness. There is no suitable display improvement technology for people with total color blindness. Therefore, existing technologies cannot provide suitable display images for people with total color blindness.

[0004] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0052] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0053] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0054] The preferred embodiment of the display improvement method based on total color blindness described in this invention, such as... Figure 2 As shown, the display improvement method based on total color blindness includes the following steps:

[0055] Step S10: Obtain the brightness information of the partitioned image, and obtain the first image brightness matrix based on the brightness information.

[0056] Please refer to the detailed process. Figure 3 This is a flowchart of step S10 in the display improvement method based on total color blindness provided by the present invention.

[0057] like Figure 3 As shown, step S10 includes:

[0058] Step S11: Obtain the image stored in the image processing chip, and segment the image to obtain multiple partition images;

[0059] Step S12: Obtain the average brightness of each partition image based on the multiple partition images, and construct the first image brightness matrix based on the average brightness.

[0060] Specifically, after the image processing chip stores an image frame, it obtains the image stored in the image processing chip and divides the image into equal parts to obtain partitioned images (for example, dividing the image into C*D partitioned images, where C refers to dividing the image into C equal parts along the horizontal axis and D refers to dividing the image into D equal parts along the vertical axis). Based on the multiple partitioned images, the average brightness of each partitioned image is obtained, and the first image brightness matrix is ​​constructed based on the average brightness.

[0061] The first image brightness matrix is:

[0062]

[0063] Where Z represents the brightness matrix of the first image, C represents the number of backlight zones on the horizontal axis of the image, and D represents the number of backlight zones on the vertical axis of the image. CD Z represents the brightness of the Cth horizontal and Dth vertical partition in the first image brightness matrix. CD The brightness range is (0, 255).

[0064] Step S20: Obtain the maximum and minimum brightness of the first image brightness matrix, and calculate the difference between the maximum and minimum brightness.

[0065] Specifically, the maximum and minimum brightness of the first image brightness matrix are obtained, and the difference between the maximum and minimum brightness is calculated. Based on the different differences, and in combination with the intervals to which the maximum and minimum brightness belong, a brightness conversion formula is selected.

[0066] Step S30: Based on the difference, the first image brightness matrix is ​​converted to obtain a second image brightness matrix, and the second image brightness matrix is ​​transmitted to the display to complete the image display.

[0067] Please refer to the detailed process. Figure 4 This is a flowchart of step S30 in the display improvement method based on total color blindness provided by the present invention.

[0068] like Figure 4 As shown, step S30 includes:

[0069] Step S31: Select the corresponding brightness conversion formula based on the magnitude of the difference and the maximum brightness, or select the corresponding brightness conversion formula based on the magnitude of the difference and the interval to which the maximum brightness and the minimum brightness belong;

[0070] Step S32: Based on the brightness conversion formula, the first image brightness matrix is ​​converted to obtain the second image brightness matrix;

[0071] Step S33: Transmit the second image brightness matrix to the backlight partition control module to obtain a new image, and then transmit the new image to the display to complete the display.

[0072] Specifically, a corresponding brightness conversion formula is selected based on the magnitude of the difference and the maximum brightness. If ΔZ ≥ 120, or Zmax ≥ 200, then Z′ = Z, where Z represents the first image brightness matrix, Zmax represents the maximum brightness of the first image brightness matrix, ΔZ represents the difference between the maximum brightness and the minimum brightness, and Z′ represents the second image brightness matrix; or a corresponding brightness conversion formula is selected based on the magnitude of the difference and the intervals to which the maximum brightness and the minimum brightness belong. The brightness conversion formula includes: if ΔZ < 120 and [Zmin, Zmax] ∈ [0, 120], then If ΔZ < 120 and [Zmin, Zmax] ∈ [20, 140], then Where β1 ranges from (10, 14); if ΔZ < 120 and [Zmin, Zmax] ∈ [40, 160], then Where β2 ranges from (14, 18); if ΔZ < 120 and [Zmin, Zmax] ∈ [60, 180], then Where β3 ranges from (18, 22); if ΔZ < 120 and [Zmin, Zmax] ∈ [80, 200], then Wherein, β4 ranges from (22, 26); where Z represents the first image brightness matrix, Zmax represents the maximum brightness of the first image brightness matrix, Zmin represents the minimum brightness of the first image brightness matrix, ΔZ represents the difference between the maximum brightness and the minimum brightness, Z′ represents the second image brightness matrix, β1 represents the first adjustment factor, β2 represents the second adjustment factor, β3 represents the third adjustment factor, and β4 represents the fourth adjustment factor; according to the brightness conversion formula, the first image brightness matrix is ​​converted to obtain the second image brightness matrix. The purpose of the conversion is to maximize the contrast of the black and white image relative to the totally blind, so that the totally blind can have a better viewing experience; the second image brightness matrix is ​​transmitted to the backlight zoning control module through the bus, and the backlight zoning control module controls the image display effect of the display.

[0073] Furthermore, the second image brightness matrix is:

[0074]

[0075] Where Z′ represents the second image brightness matrix, C represents the number of horizontal backlight zones in the image, and D represents the number of vertical backlight zones in the image. CD This represents the brightness of the Cth horizontal and Dth vertical partition in the second image brightness matrix.

[0076] Furthermore, such as Figure 5As shown, based on the above-described display improvement method for total color blindness, the present invention also provides a display improvement system for total color blindness, the display improvement system for total color blindness comprising:

[0079] The signal processing chip 53 is used to process the image luminance matrix of the video in the full color blindness mode. The signal processing chip includes a luminance matrix calculation module 101, a luminance matrix information recognition module 102, and a luminance matrix conversion module 103.

[0080] The brightness matrix calculation module 101 is used to calculate the difference between the maximum brightness and the minimum brightness of the first image brightness matrix obtained based on the brightness information.

[0082] The brightness matrix conversion module 103 is used to select a corresponding conversion formula based on the relationship between the maximum brightness, the minimum brightness and the difference, and convert the first image brightness matrix to obtain the second image brightness matrix through the conversion formula;

[0083] The backlight partition driving module 54 is used to receive the second image brightness matrix transmitted through the bus, and adjust the video image based on the second image brightness matrix to obtain a new video;

[0084] Display module 55 is used to display the input video on the monitor.

[0085] Furthermore, after the video input module 51 inputs the video, the user mode selection module 52 receives the mode selected by the user, which includes a normal mode and a total colorblindness mode. If the normal mode is selected, the backlight partition driving module 54 directly transmits the input video to the display module 55, and the display module 55 plays the video. If the total colorblindness mode is selected, the signal processing chip processes the video. The signal processing chip includes a luminance matrix calculation module 101, a luminance matrix information recognition module 102, and a luminance matrix conversion module 103. The processed video is then input to the backlight partition driving module 54, which transmits the processed video to the display module 55, and the display module 55 plays the video. This provides a personalized viewing mode for users with total colorblindness, enabling them to watch more comfortably and improving their happiness index.
