[0003] When an electronic device displays visual content through a screen, the screen emits blue light. Long-term exposure of the eyes to a high-intensity blue light environment may increase eye fatigue. Therefore, how to reduce the user's eye fatigue during the use of the screen is an urgent problem to be solved. Summary of the invention

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0026] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0027] The nouns or terms involved in this application specification are explained below.

[0028] Red, green, green, blue, RGGB arrangement: is a commonly used color filter array (CFA) arrangement. The RGGB arrangement is a form of Bayer color filter array (Bayer CFA) arrangement, which arranges red (Red, R), green (Geen, G), green (Geen, G), and blue (Blue, B) filters in a specific pattern above the pixels of the display screen so that the pixels of the display screen can display different colors.

[0029] Liquid Crystal Display (LCD): A type of flat panel display used to display visual content such as images, text, and symbols.

[0030] Organic Light-Emitting Diode (OLED), also known as organic electroluminescence display or organic light-emitting semiconductor (OLED), refers to the phenomenon that organic semiconductor materials and luminescent materials emit light through carrier injection and recombination under the drive of an electric field.

[0031] OLED screen: OLED screen is different from traditional LCD screens in that it does not require a backlight. In an OLED screen, each pixel is self-luminous, which means they can be turned on and off individually, providing true black and higher contrast. Since OLED screens do not require an additional backlight layer, devices equipped with OLED screens are lighter and thinner.

[0032] The following is a detailed description of the screen display method, device, electronic device and medium provided by the embodiments of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0033] The screen display method, device, electronic device, medium and computer program product provided in the embodiments of the present application can be applied to the scene of displaying a screen through a screen. The screen can be any possible screen such as a shooting screen, a video playback screen, an image display screen, a chat screen, a novel reading screen, a web browsing screen, a document editing screen, etc.

[0034] It can be understood that the image display method provided in the embodiment of the present application can reduce the first channel value of the image content in the non-gaze area of ​​the screen to reduce the blue light emission of the screen, thereby reducing the user's eye fatigue when using the screen.

[0035] The following uses some specific screen usage scenarios as examples to illustrate the screen display method provided in the embodiments of the present application.

[0036] Exemplarily, take a user browsing a web page as an example. The electronic device can determine the user's gaze area on the screen, and then the electronic device can reduce the R channel value of the web page content corresponding to the non-gaze area in the web page to be displayed to obtain the target picture. Then the electronic device can display the target picture on the screen. In this way, on the one hand, since the R channel value of the web page content in the gaze area remains unchanged, the color distortion of the web page content in the gaze area is small, so that the user has a better color experience; on the other hand, since the R channel value of the web page content in the gaze area is reduced, the blue light emission in the non-gaze area is small, so that less blue light can enter the human eye; thereby, not only can the user's color experience of watching the video be ensured, but also the user's eye fatigue during the process of watching the video using the electronic device can be avoided.

[0037] Exemplarily, take a user watching a video screen as an example. Before the electronic device displays a video screen on the screen, the electronic device can first determine the user's gaze area on the screen, and then the electronic device can reduce the R channel value of the video content corresponding to the non-gaze area in the video screen to obtain the target screen. Then the electronic device can display the target screen on the screen. In this way, on the one hand, since the R channel value of the video content in the gaze area remains unchanged, the color distortion of the video content in the gaze area is small, so that the user has a better color experience; on the other hand, since the R channel value in the gaze area is reduced, the blue light emission in the non-gaze area is small, so that less blue light can enter the human eye. In this way, not only can the user's color experience of watching videos be ensured, but also the degree of eye fatigue of users in the process of watching videos using electronic devices can be avoided.

[0038] In the screen display method, device, electronic device, medium and computer program product provided in the embodiments of the present application, the user's gaze area on the screen can be determined, and the first channel value of the target screen content in the screen to be displayed can be reduced to obtain the target screen, and the first screen content corresponds to the non-gaze area of ​​the screen except the gaze area; the target screen is displayed on the screen; wherein the first channel value includes the blue B channel value. Through this solution, since the human eye pays less attention to the color of other areas except the gaze area, by reducing the first channel value of the first screen content corresponding to the non-gaze area, less blue light can enter the user's eyes while ensuring the display effect of the gaze area, thereby reducing the user's eye fatigue when using the screen.

[0039] The screen display method provided in the embodiment of the present application is performed by a screen display device, which may be an electronic device, or a functional module or entity in an electronic device, and the embodiment of the present application does not limit this. The screen display method provided in the embodiment of the present application will be exemplarily described below using an electronic device as an example.

[0040] The present application embodiment provides a screen display method, Figure 1 A schematic diagram of a process flow of a screen display method provided in an embodiment of the present application is shown. Figure 1 As shown, the screen display method provided in the embodiment of the present application may include the following steps 101 to 103.

[0041] Step 101: The electronic device determines a first area on a screen.

[0042] The first area may be the user's gaze area on the screen.

[0043] In some embodiments of the present application, the electronic device may capture an eye image of the user and determine a gaze area of ​​the user on the screen based on the eye image.

[0044] For example, the electronic device may use a front camera in the electronic device to capture an eye image of the user.

[0045] In some embodiments of the present application, the number of eye images collected by the electronic device is not limited. That is, the electronic device can collect at least one eye image of the user, and determine the user's gaze area on the screen based on the at least one eye image.

[0046] In some embodiments of the present application, the electronic device may determine the user's gaze direction using an eye movement algorithm based on the at least one eye image, and then determine the user's gaze area on the screen based on the gaze direction.

[0047] Among them, the eye movement algorithm may include any of the following: pupil-corneal reflection algorithm, gaze tracking algorithm, geometry-based eye movement algorithm, 2-dimensional (D) regression-based eye movement algorithm, 3D model-based eye movement algorithm, cross-ratio-based eye movement algorithm, appearance-based eye movement algorithm, or any other algorithm that can calculate the gaze direction based on eye images.

[0048] In some embodiments of the present application, the electronic device may determine the screen area within a preset range centered on the user's gaze direction as the user's gaze area on the screen. In some embodiments of the present application, the preset range may include a horizontal range and a vertical range.

[0049] In some embodiments of the present application, the horizontal range may be a first horizontal viewing angle range with the user's gaze direction being 0°, and the vertical range may be a first vertical viewing angle range with the user's gaze direction being 0°.

[0050] For example, the first horizontal viewing angle range may be ±30°, and the first vertical viewing angle range may be ±15°. Of course, the first horizontal viewing angle range is a range of ±20° with the user's gaze direction being 0°, and the first vertical viewing angle range may be a range of ±10° with the user's gaze direction being 0°, which may be specifically determined based on the human factors experimental data results of color.

[0051] In some embodiments of the present application, the human factors experimental data of color can be Figure 2A and Figure 2B shown. Specifically, Figure 2A Schematic diagram of the prediction results of the deep kernel learning color discrimination prediction model. Figure 2A The L, M, and S in the image represent the luminance, red-green, and blue-yellow channels, respectively. Figure 2A An ellipse 20, an ellipse 21 and a black cross “+” can represent a discrimination threshold; wherein all colors within the ellipse threshold are perceptually indistinguishable from the center (black cross “+”) color, the eccentricity corresponding to ellipse 20 is 10°, and the eccentricity corresponding to ellipse 21 is 25°. Figure 2A It can be seen that, a, due to the high density of retinal receptors in the fovea, the retina's ability to distinguish color differences decreases as the eccentricity of the retina increases; b, the corresponding discrimination thresholds for different colors may be different. Figure 2B This is a schematic diagram of the results of the standard (Standard, A) RGB color discrimination prediction model when the retinal eccentricity is 25°. Figure 2A and Figure 2B It can be determined that the color resolution of the fovea is the greatest, and as the eccentricity of the retina increases, the color discrimination ability of the retina decreases. In other words, the human eye has the greatest ability to distinguish colors located in the center of the field of view, and as the viewing angle increases, the human eye's ability to distinguish colors gradually decreases, and the ability to distinguish colors at the edge of the field of view is the lowest. Based on this conclusion, it can be seen that in the picture display scene, by reducing the B channel value of the non-fixated area of ​​the screen (such as the area at the edge of the field of view), the blue light emitted by the screen can be reduced, thereby reducing the eye fatigue of the human eye when watching the screen.

[0052] In some embodiments of the present application, the horizontal range may be a first horizontal distance range centered on the gaze point on the screen in the direction of the user's line of sight; the vertical range may be a first vertical distance range centered on the gaze point on the screen in the direction of the user's line of sight. Figure 3A As shown, assuming that the coordinates of the user's gaze point on the screen 20 are (0, 0), the first horizontal distance is ±a, and the first vertical distance range can be ±b. The values ​​of a and b can be the same or different.

[0053] For example, the value of a can be 35 mm, and the value of b can also be 40 mm.

[0054] For example, the value of a can be 40 mm, and the value of b can also be 40 mm.

[0055] In some embodiments of the present application, Figure 3A As shown, the user's gaze area on the screen is the display area shown in the dotted frame, and the non-gaze area is the display area outside the dotted frame on the screen.

[0056] In some embodiments of the present application, Figure 3A As shown, the coordinates of the upper left corner of the fixation area are (-a, b).

[0057] In some embodiments of the present application, the electronic device may periodically monitor the user's gaze area on the screen.

[0058] In some embodiments of the present application, the electronic device may determine the user's gaze area on the screen before displaying the interface to be displayed on the screen.

[0059] In some embodiments of the present application, each pixel of the screen may include an R channel, a G channel, and a B channel, and the electronic device may light up different channels of each pixel so that each pixel emits light of a corresponding color.

[0060] In some embodiments of the present application, the above screen supports the RGGB data format.

[0061] In some embodiments of the present application, the pixels in the above-mentioned screen may be pixels illuminated by a backlight, that is, the screen is a display screen with a backlight, such as a liquid crystal display screen.

[0062] In some embodiments of the present application, the pixels in the above screen may be independent light-emitting pixels, that is, each pixel may be individually lit without backlight. For example, the screen may be an OLED screen.

[0063] In some embodiments of the present application, the electronic device may be an extended reality (XR) device. For example, it may be an XR head-mounted display device or an XR wearable device. Of course, the electronic device may also be any other smart terminal with a screen, such as a mobile phone, a tablet computer, a smart TV, or the like.

[0064] Step 102: The electronic device reduces the first channel value of the first picture content in the picture to be displayed to obtain a target picture.

[0065] The first screen content corresponds to a second area, and the second area is an area of ​​the screen other than the first area; the first channel value may include a B channel value.

[0066] It should be noted that in the embodiments of the present application, "first area" and "user's gaze area on the screen" have the same meaning and can be interchanged; "second area" and "non-gaze area on the screen except for the gaze area" have the same meaning and can be interchanged. To simplify the description, in the following embodiments, "second area" can be interchanged with "non-gaze area", and "second area" can be interchanged with "gaze area".

[0067] In some embodiments of the present application, “the first screen content corresponds to the second area” means that the display area of ​​the first screen content on the screen is located in the non-attention area.

[0068] It is understandable that in the visible light spectrum, blue light is the most damaging to the human eye, especially the retina of the human eye. Long-term exposure of the human eye to blue light may increase the risk of eye damage. Reducing the B channel value of the picture content can reduce the blue light component in the picture content, thereby reducing the impact of blue light.

[0069] Specifically, the smaller the B channel value of the picture content, the smaller the blue light emission of the screen after the electronic device displays the picture content on the screen. The smaller the blue light emission of the screen during the user's use of the screen. The lower the user's eye fatigue. Therefore, reducing the B channel value of the first picture content can reduce the blue light emission of the screen, thereby reducing the user's eye fatigue during the use of the screen. In other words, the human eye is not sensitive to the color of the non-gaze area, and the blue light can be reduced by reducing the B channel value in the RGGB domain, allowing less blue light to enter the user's eyes and reduce the user's eye fatigue.

[0070] It should be noted that since the electronic device can reduce the B channel value of the first picture content corresponding to the non-gaze area in the picture to be displayed, the blue light emission of the screen can be reduced without adding additional hardware to the electronic device. Therefore, the picture display method provided in the embodiment of the present application has high versatility.

[0071] In some embodiments of the present application, the electronic device reducing the first channel value of the first screen content can be understood as: the electronic device reducing the channel value of the first channel of the first screen content.

[0072] For example, assuming that the first channel is the B channel, the electronic device may reduce the channel value of the B channel of the first picture content.

[0073] In some embodiments of the present application, the electronic device may first convert the data format of the image to be displayed from the luminance and chrominance separation format (YUV) format to the red, green, blue (Red, Green, Green, Blue, RGGB) format. It can be understood that the "Y" in the YUV format represents brightness (Luminance or Luma), that is, the grayscale value, and "U" and "V" represent chrominance (Chrominance or Chroma), which is used to describe the color and saturation of the image and is used to specify the color of the pixel; the data in the RGGB format has three channels, namely the R channel, the G channel and the B channel, so that the electronic device can individually control the channel value of each channel in the image to be displayed.

[0074] For example, Figure 3B The picture 30 shown is a picture to be displayed in YUV format. Figure 3B The picture 31 shown is a schematic diagram of the interface to be displayed in RGGB format. Among them, the picture 30 includes the picture content 32 corresponding to the gaze area and the picture content 33 corresponding to the non-gaze area; the picture 31 includes the picture content 32' corresponding to the gaze area and the picture content 33' corresponding to the non-gaze area. It can be understood that Figure 3B The labels R, G and B in represent the R channel value, G channel value and B channel value respectively.

[0075] In some embodiments of the present application, the picture to be displayed in RGGB format may also be referred to as a color gamut map of the picture to be displayed.

[0076] In some embodiments of the present application, the electronic device may first determine the gaze area and then convert the data format of the image to be displayed into the RGGB format, or the electronic device may first convert the data format of the image to be displayed into the RGGB format and then determine the gaze area. The specific determination may be made according to actual usage requirements.

[0077] In some embodiments of the present application, the data format of the target picture is RGGB format.

[0078] In some embodiments of the present application, the electronic device can reduce the first channel value of the first screen content in the to-be-displayed screen while keeping the first channel value of the second screen content in the to-be-displayed interface unchanged to obtain the target screen, wherein the second screen content corresponds to the user's gaze area on the screen, that is, the second screen content corresponds to the first area.

[0079] In some embodiments of the present application, the second screen content corresponds to the first area, which means that the display area of ​​the second screen content on the screen is located in the user's gaze area on the screen, that is, located in the first area.

[0080] In some embodiments of the present application, the electronic device can divide the interface to be displayed into a first screen content and a second screen content according to the user's gaze area on the screen, wherein the first screen content corresponds to the non-gaze area and the second screen content corresponds to the gaze area; thereby, the electronic device can reduce the first channel value of the first screen content.

[0081] In some embodiments of the present application, the electronic device may divide the interface to be displayed into first screen content and second screen content according to the position information of the gaze area and the correspondence between the screen content of the screen to be displayed and the screen area of ​​the screen.

[0082] For example, assuming that the size of the to-be-displayed image in RGGB format is 2460*2460, and the size of the gaze area is 800*800, and the coordinate information of the upper left corner of the gaze area is (800, 800), then Figure 4 As shown, the electronic device can divide the to-be-displayed screen 40 into the first screen content 41 and the second screen content 42 according to the coordinate information and the above correspondence. It can be understood that Figure 4 The separate display of the first screen content 41 and the second screen content 42 is only used to illustrate the relative position relationship between the first screen content and the second screen content, and does not mean that the electronic device has performed a region segmentation process on the screen to be displayed. In other words, in the actual implementation of the electronic device, only the position information of the first screen content, such as the coordinate information, can be marked in the screen to be displayed, without performing a segmentation operation on the screen to be displayed. Of course, in the actual implementation, the electronic device can also segment the rendered screen to obtain the first screen content and the second screen content. This application is not limited thereto.

[0083] In some embodiments of the present application, the first screen content may include multiple content units, each content unit corresponds to a pixel in the second area; the above step 102 may be implemented by the following step 102A.

[0084] Step 102A: The electronic device reduces the first channel values ​​of the plurality of content units according to the first strategy to obtain a target picture.

[0085] The first strategy includes any of the following:

[0086] 1) The reduction range of the first channel value of the content unit increases as the distance between the pixel corresponding to the content unit and the first area increases;

[0087] 2) the first channel value after the content unit is reduced decreases as the distance between the pixel corresponding to the content unit and the first area increases;

[0088] 3) the first channel value after the content unit is reduced decreases as the viewing angle corresponding to the pixel corresponding to the content unit increases;

[0089] 4) the reduction range of the first channel value of the content unit increases as the viewing angle corresponding to the pixel corresponding to the content unit increases;

[0090] 5) the first channel values ​​of the content units in the non-fixation area decrease by the same amount;

[0091] 6) The first channel values ​​after the content units in the non-attention area are reduced are the same.

[0092] In some embodiments of the present application, each content unit is displayed by a pixel corresponding to each content unit.

[0093] In some embodiments of the present application, the distance between the pixel corresponding to the content unit and the first area can be: the distance between the pixel corresponding to the content unit and the boundary line of the first area, or the distance between the pixel corresponding to the content unit and the center point of the first area, etc., which can be determined according to actual usage requirements.

[0094] For the convenience of description, the “distance between the pixel corresponding to the content unit and the first area” may be referred to as “the distance between the content unit and the first area” or “the distance from the content unit to the first area”.

[0095] In some embodiments of the present application, in the above 1), the greater the distance between the content unit and the first area, the greater the reduction range of the first channel value of the content unit.

[0096] For example, assuming that the B channel value of content unit 1 is the same as the B channel value of content unit 2, the distance between content unit 1 and the gaze area is d1, the distance between content unit 2 and the first area is d2, and d1 is less than d2, then: the decrease in the first channel value of content unit 1 is less than the decrease in the first channel value of content unit 2, so that the first channel value of content unit 1 after the decrease is greater than the first channel value of content unit 2 after the decrease.

[0097] In some embodiments of the present application, in the above 2), the greater the distance between the content unit and the first area, the greater the reduction in the first channel value of the content unit, and thus the smaller the first channel value of the content unit after the first channel value is reduced.

[0098] It can be seen that in the above 2), the first channel value after the content unit is reduced is mainly determined by the distance between the content unit and the first area.

[0099] In some embodiments of the present application, the viewing angle corresponding to a pixel may be: the angle between a line between the pixel and a human eye and a gaze direction of the user.

[0100] For example, Figure 5A As shown, the user's eye gaze point on the screen 51 is M, the gaze direction is the direction indicated by the arrow 52, ​​and the first area 53 is Figure 5A The area shown by the thick black line in FIG. 5 is the area except area 53. The second area is the rest of the area except area 53. It can be seen that the viewing angle corresponding to pixel A in the second area is angle a, the viewing angle corresponding to pixel B in the second area is angle b, and the viewing angle corresponding to pixel C in the second area is angle c. That is, the viewing angle corresponding to the pixel is the angle between the line between the pixel and the human eye and the gaze direction of the user.

[0101] For example, Figure 5B As shown, assuming that the gaze direction is 0° and the viewing angle range corresponding to the gaze area is 30°, the electronic device can keep the first channel value of the content unit corresponding to the pixels within the 30° range in the image to be displayed unchanged, and reduce the B channel value of the content unit corresponding to the pixels outside 30° in the image to be displayed.

[0102] In some embodiments of the present application, in the above 3), the larger the viewing angle corresponding to the pixel corresponding to the content unit is, the greater the reduction range of the first channel value of the content unit is.

[0103] For example, Figure 5B As shown, the reduced B channel value of the content unit=the original B channel value of the content unit*(1-the reduction amplitude of the first channel value of the content unit).

[0104] In some embodiments of the present application, in the above 4), the larger the viewing angle corresponding to the pixel corresponding to the content unit is, the smaller the first channel value after the content unit is reduced is.

[0105] In some embodiments of the present application, in the above 1) to 4), if Figure 4 As shown, after the B channel value of the first screen content 42 is reduced, the B channel value of the first screen content 42 after the B channel value is reduced begins to decrease from the gaze point area (that is, the blank area in 42) outward, and the gaze area (refer to Figure 4 41) in the figure has no color cast, and the non-attention area transitions from no color cast to color cast. According to the conclusion of human factor experiments on human eyes, the human eye is not sensitive to color cast in the non-attention area. Therefore, as long as the color of the non-attention area has a transition, it will not affect the user's experience of using the electronic device. In this way, the user's eye fatigue can be reduced without affecting the user's experience of using the electronic device.

[0106] In some embodiments of the present application, the first channel value of the content unit corresponding to the non-fixation area is gradually reduced in the above 1) to 4), which is more in line with the objective law of the retina to distinguish colors. In this way, the display effect of the screen can be improved and the user experience can be improved on the basis of reducing the user's eye fatigue.

[0107] In this way, since the electronic device can adjust the first channel values ​​of multiple content units in the non-attention area according to the strategy that the reduction amplitude of the first channel value of the content unit increases as the distance between the pixel corresponding to the content unit and the attention area increases, the first channel value of the content unit after reduction decreases as the distance between the pixel corresponding to the content unit and the attention area increases, the reduction amplitude of the first channel values ​​of multiple content units is the same, or the first channel values ​​of multiple content units after reduction are the same, it can not only reduce the blue light emission of the screen, but also improve the flexibility and diversity of reducing the first channel value of the picture content in the non-attention area.

[0108] In some embodiments of the present application, the first channel value may further include at least one of a G channel value and an R channel value.

[0109] For example, the electronic device may reduce the R channel value, the G channel value, and the B channel value of the first picture content.

[0110] For example, the electronic device may reduce the R channel value and the G channel value of the first picture content.

[0111] For example, the electronic device may reduce the R channel value and the R channel value of the first picture content.

[0112] It can be understood that reducing at least one of the G channel value and the R channel value of the first screen content can achieve the effect of reducing the display brightness of the non-attention area, so that less light can enter the human eye. The less light enters the human eye, the less eye fatigue the human eye suffers. In other words, the user's eye fatigue can also be reduced to a certain extent by the brightness of the non-attention area.

[0113] In this way, since reducing at least one of the R channel value and the G channel value of the first screen content can reduce the display brightness of the first screen content, after the electronic device displays the target screen on the screen, the display brightness of the non-attention area is lower, so that less light can enter the user's eyes, thereby further reducing the user's eye fatigue when using the screen.

[0114] In some embodiments of the present application, if the electronic device performs segmentation processing on the screen to be displayed, that is, the first screen content and the second screen content are two different small screens, then the electronic device can reduce the first channel value of the first screen content, and then synthesize the first screen content after reducing the first channel value with the first screen content to obtain the target screen.

[0115] For example, Figure 6 As shown, the electronic device can combine the first picture content after reducing the B channel value with the second picture content 61 to obtain a target picture 62.

[0116] Step 103: The electronic device displays the target image on the screen.

[0117] In some embodiments of the present application, the electronic device displaying the target screen on the screen may include: the electronic device displays the first screen content in the target screen in the non-attention area, and displays the second screen content in the target screen in the attention area, so that a display image can be obtained. In this way, the user can see the target screen through the screen.

[0118] In some embodiments of the present application, after the electronic device displays the target image on the screen, the amount of blue light emitted per unit area in the non-attention area is less than the amount of blue light emitted per unit area in the attention area. Thus, compared with the attention area, the color of the image content in the non-attention area is yellowish.

[0119] In some embodiments of the present application, the display resolution of the screen content in the first area is greater than the display resolution of the screen content in the second area.

[0120] For example, the display resolution of the picture content in the fixation area may be 4k, and the display resolution of the picture content in the non-fixation area may be 1k.

[0121] For example, the display resolution of the picture content in the fixation area may be 8k, and the display resolution of the picture content in the non-fixation area may be 2k.

[0122] It is understandable that the fixation area of ​​the human eye is the area that the user pays most attention to, so the image content in the fixation area is displayed with a higher resolution to improve the user's color experience. The image content in the non-fixation area is displayed with a lower resolution to save display resources of the electronic device.

[0123] In some embodiments of the present application, the display resolution of the picture content in the gaze area may also be referred to as the gaze point display resolution.

[0124] In this way, since the user pays less attention to the non-attention area, the electronic device can use a smaller display resolution to display the image content in the non-attention area, so as to save the display resources of the electronic device.

[0125] The infringement visibility description of the screen display method provided in the embodiment of the present application may include:

[0126] A1. Since the electronic device can first reduce the B channel value of the picture content corresponding to the non-attention area in the picture and then display the picture, when the screen displays the picture, the color of the picture content in the attention area is slightly different from that in the non-attention area, or the color of the picture content in the non-attention area has a color cast.

[0127] A2. Since the electronic device can also reduce at least one of the G channel value and the R channel value of the picture content corresponding to the non-gaze area in the picture, since at least one of the G channel value and the R channel value of the picture content is reduced, the brightness of the picture content can be reduced. Therefore, when the screen displays the picture, there is a slight difference in brightness between the picture content in the gaze area and the picture content in the non-gaze area; for example, the picture content in the gaze area is brighter than the picture content in the non-gaze area.

[0128] The display method provided in the embodiment of the present application is described below with reference to specific examples.

[0129] For example, take a user using an electronic device to take a landscape image as an example. Figure 7 A schematic diagram of a process flow of a screen display method provided in an embodiment of the present application, such as Figure 7 As shown:

[0130] Step 71: The electronic device collects eye images of the user through an eye tracking camera.

[0131] It can be understood that the eye tracking camera can be called an eye camera. The eye tracking camera can obtain image data of the user's eyes, that is, the user's eye image.

[0132] In some embodiments of the present application, the eye tracking camera may be any camera in the device whose shooting direction is toward the user, such as a front camera in the electronic device.

[0133] Step 72: The electronic device calculates the user's gaze area on the screen based on the user's eye image using an eye movement algorithm.

[0134] That is, the electronic device calculates the position of the user's gaze area based on the image data of the user's eye image through an eye movement algorithm.

[0135] Step 73: The electronic device collects landscape images through an RGB camera.

[0136] It can be understood that the above-mentioned landscape image is the picture to be displayed in the above-mentioned embodiment.

[0137] In some embodiments of the present application, the RGB camera may be any camera in an electronic device, such as a rear camera. It is understood that the execution order of step 71 and step 73 is not limited, that is, step 71 and step 72 may be executed simultaneously, or step 73 may be executed first and then step 71, or step 71 may be executed first and then step 72.

[0138] Step 74: The electronic device identifies a gazed image area and a non-gazed image area in the landscape image according to the gazed area of ​​the user on the screen.

[0139] The fixation image area corresponds to the fixation area in the screen, and the non-fixation image area corresponds to the non-fixation area in the screen. The fixation image area is the second screen content, and the non-fixation image area is the first screen content.

[0140] Step 75: The electronic device converts the data format of the landscape image after dividing the image area from the YUV format to the RGGB format to obtain an RGGB image.

[0141] Step 76: The electronic device divides the RGGB image into an RGGB attention area image and an RGGB non-attention area image according to the recognition result of the landscape image.

[0142] Step 77: The electronic device reduces the B channel value of the RGGB non-attention area image according to the first strategy to obtain the RGGB non-attention area result image.

[0143] Step 78: The electronic device synthesizes the RGGB non-attention area result image with the RGGB attention area image to obtain a target display screen.

[0144] Step 79: The electronic device displays the target display image on the screen.

[0145] In some embodiments of the present application, the electronic device may display image data of the target display interface on the screen.

[0146] In this way, since the human eye is not sensitive to the color of the non-attention area, the blue light can be reduced by reducing the B channel value of the picture content in the non-attention area in the RGGB domain, allowing less blue light to enter the user's eyes and reduce the user's eye fatigue.

[0147] In the screen display method provided in the embodiment of the present application, since the human eye pays less attention to the colors of areas other than the gaze area, the electronic device can ensure the display effect of the gaze area by reducing the first channel value of the first screen content corresponding to the non-gaze area. This allows less blue light to enter the user's eyes, thereby reducing the degree of eye fatigue of the user when using the screen.

[0148] In some embodiments of the present application, after the above step 103, the screen display method provided by the embodiment of the present application may further include the following step 104.

[0149] Step 104: When the first area is updated, the electronic device updates the first channel value of the target screen according to the second strategy. The second strategy may include: the first channel value of the third screen content in the first area after the update is the same as the original first channel value corresponding to the third screen content; the first channel value of the fourth screen content in the second area after the update is less than the original first channel value corresponding to the fourth screen content.

[0150] The original first channel value corresponding to the screen content is determined by the original data of the screen content. It can be understood that when the user's line of sight changes, the user's gaze area on the screen is updated accordingly. After the gaze area, i.e., the first area, is updated, in order to ensure the user's color experience, the electronic device can update the first channel value of the target screen according to the second strategy to improve the screen display effect and user experience.

[0151] In some embodiments of the present application, the purpose of the second strategy is to increase the first channel value of the third picture content in the updated gaze area to improve the user's color experience, and to reduce the first channel value of the fourth picture content in the updated non-gaze area to reduce the amount of blue light entering the human eye.

[0152] In some embodiments of the present application, the electronic device can reduce the first channel value of the fourth screen content according to the first strategy. For the description of the first strategy, refer to the relevant description in the above embodiments.

[0153] In some embodiments of the present application, the original data of the screen content is data in the screen data of the screen to be displayed. For example, assuming that the screen to be displayed is an image captured by a camera, the image data of the image includes the original data of a screen content in the target screen, and the first channel value of the original data is the original first channel value corresponding to the screen content.

[0154] It can be understood that the original first channel value corresponding to the picture content is the first channel value with the best display effect of the picture content.

[0155] In this way, when the target picture is displayed on the screen, when the gaze area (i.e., the first area) is updated, on the one hand, the electronic device can update the first channel value of the third picture content in the updated gaze area to the original first channel value of the third picture content, so that the updated third picture content can have a better display effect; on the other hand, the electronic device can reduce the first channel value of the fourth picture content in the updated non-gaze area (i.e., the updated second area), so that the blue light emission in the updated non-gaze area can be reduced, thereby reducing the amount of blue light entering the human eye, and further reducing the user's eye fatigue when using the screen.

[0156] The screen display method provided in the embodiment of the present application can be executed by a screen display device. In the embodiment of the present application, the screen display device provided in the embodiment of the present application is described by taking the screen display method executed by the screen display device as an example.

[0157] The embodiment of the present application provides a picture display device, Figure 8 The structure diagram of the screen display device provided in the embodiment of the present application is shown as follows: Figure 8 As shown, the screen display device 80 may include a determination module 81, a processing module 82 and a display module 83;

[0158] The determining module 82 is used to determine a first area on the screen, where the first area is a gaze area of ​​the user on the screen;

[0166] The first channel value after the content unit is reduced decreases as the distance between the pixel corresponding to the content unit and the first area increases;

[0167] The reduction range of the first channel value of the content unit increases as the viewing angle corresponding to the pixel corresponding to the content unit increases;

[0169] In some embodiments of the present application, the first channel value also includes at least one of a green G channel value and a red R channel value.

[0175] In some embodiments of the present application, the display resolution of the screen content in the first area is greater than the display resolution of the screen content in the second area.

[0176] In the picture display device provided in the embodiment of the present application, since the human eye pays less attention to the colors of areas other than the gaze area, by reducing the first channel value of the first picture content corresponding to the non-gaze area, less blue light can enter the user's eyes while ensuring the display effect of the gaze area, thereby reducing the user's eye fatigue when using the screen.
