[0051] Here, the exemplary embodiments will be described in detail, and the examples are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are only examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0052] The display processing method described in the embodiments of the present disclosure is applicable to electronic devices such as mobile phone smart terminals, game consoles, laptop computers, and PADs, and can be applied to applications such as e-books, text file displays, and image displays. As long as display output is required, the display processing method of the embodiments of the present disclosure is applicable.

[0053] Figure 1 It is a schematic flowchart of a display processing method shown in the embodiments of the present disclosure. As Figure 1 shown, the display processing method of the embodiments of the present disclosure includes the following steps:

[0054] S11. Obtain the layer data of the area to be displayed.

[0055] In the display processing method of the embodiments of the present disclosure, it can be applied to electronic devices. The electronic device can be a mobile phone, a game console, a wearable device, a virtual reality device, a personal digital assistant, a laptop computer, a tablet computer, or a television terminal, etc. The applicable scenarios can be the display of e-books, text files, images, etc. of the electronic device. Through the display processing method of the embodiments of the present disclosure, a better display effect can be provided for users, which will not cause visual fatigue of the viewing users and enables users to have a better experience when viewing the screen.

[0056] In the embodiments of the present disclosure, before outputting the image to be displayed, it needs to be subjected to diffuse reflection processing, especially for e-books or text applications, etc. When the relevant processing settings or requests are selected using the display processing method of the embodiments of the present disclosure, it is necessary to obtain the display layer data and perform diffuse reflection processing on it. The embodiments of the present disclosure support both diffuse reflection processing of all layer data to be displayed and diffuse reflection processing of the display of corresponding applications. Specifically, obtain the layer data of all visible display areas, store the obtained layer data in an array, and draw the layer data in the array into the frame buffer object (FrameBufferObject) to be displayed in the form of layer painting (drawLayers). The embodiments of the present disclosure take the Android operating system as an example for illustration. Those skilled in the art should understand that the processing method of the embodiments of the present disclosure is also applicable to other operating systems such as Windows, except that the commands and code implementations for display processing are different. In the embodiments of the present disclosure, before performing the display area drawing calculation, SurfaceFlinger will obtain all the current visible display area Layers. These visible Layers are stored in an array of LayerSetting, and finally these visible Layers are drawn into the FrameBufferObject to be displayed through the drawLayers method, denoted as FBO 0 .

[0057] S12. Determine the intensity of the ambient light.

[0058] In an embodiment of the present disclosure, the detection and measurement of the ambient light intensity can be achieved by setting a light intensity detection sensor, or the collected ambient light can be converted into a corresponding electrical signal through a photoelectric converter, and a corresponding electrical signal detection program is set in the electronic device to calculate the intensity of the ambient light. In the embodiment of the present disclosure, after the display image is subjected to diffuse reflection processing, it is also necessary to consider the influence of the current ambient light on the display image to simulate the display effect of an actual object. In the embodiment of the present disclosure, the intensity of the ambient light, where the intensity of the ambient light is the same at each point of the object, can be considered to be uniformly superimposed on the brightness of the object. By considering the ambient light in the embodiment of the present disclosure for the display image to be displayed, the display image can be made closer to the feeling of a real object, and the viewing experience of the user is better. The intensity of the ambient light can be determined based on the intensity of the ambient light illumination within a set distance and collection area, and the determined intensity is used as the intensity of the ambient light.

[0059] S13. Calculate the diffuse reflection noise parameter according to the light source position information and the intensity of the ambient light.

[0060] In an embodiment of the present disclosure, information on the light source position of the display unit is obtained, a diffuse reflection model matching the light source position is determined, and the diffuse reflection parameters of each display area corresponding to the display screen are calculated based on the diffuse reflection model; specifically, diffuse reflection refers to the phenomenon that a rough object surface reflects light equally in all directions, that is, the phenomenon of equal scattering in all directions. For diffuse reflection, the reflection is completely random, so it can be considered that the distribution in any reflection direction is the same, but the intensity of the diffuse reflection light is positively correlated with the angle of the incident light, that is, the intensity of the reflected light is proportional to the cosine value of the angle between the surface normal and the light source direction. Based on this, when the electronic device sets the diffuse reflection model of the display screen, it is necessary to consider the specific position of the light source of the display screen. For example, the position of the light source on the back panel of the display screen and the angular relationship between the light source position and each area of the display screen can be determined to generate the diffuse reflection model of the display screen, and the intensity of the diffuse reflection light can be determined according to the display area corresponding to the layer to be displayed.

[0061] Measure the intensity of the ambient light, and add the intensity of the ambient light and the diffuse reflection parameter to the corresponding display parameters of each display area corresponding to the display screen.

[0062] Add diffuse reflection noise particles to the layer generated in the FBO using the diffuse reflection lighting model in the shader 0 For diffuse reflection, the position of the viewing angle is not important because the reflection is completely random, so it can be considered that the distribution in any reflection direction is the same, but the angle of the incident light is important.

[0063] In the embodiments of the present disclosure, the diffuse light reflection conforms to Lambert's law. The intensity of the reflected light is proportional to the cosine value of the angle between the surface normal and the light source direction, and its calculation method is as follows:

[0064]

[0065] Where C diffuse represents how much radiation the object surface scatters in each direction, and C light represents the radiation intensity of the light source, M diffuse represents the reflection coefficient. Different materials have different reflection coefficients. For a determined object to be displayed, its reflection coefficient is determined, that is, a constant. l is the vector from the vertex to the light source illumination direction, and n is the surface normal vector of the display area.

[0066] For the convenience of calculation, when calculating the diffuse light, the vertex normal vector and the light source illumination direction vector can be normalized respectively, and then the above formula is used to calculate the intensity of the diffuse light of each display area. And through the detected ambient light intensity, it is fused with the sum of the above diffuse light as the display parameter of the layer data of the area to be displayed.

[0067] S14. Add diffuse noise to the layer data of the area to be displayed according to the diffuse noise parameter, merge and render the layer data with added diffuse noise, and output.

[0068] In the embodiments of the present disclosure, taking the Android operating system as an example, by calling the SurfaceFinger instance, all layer data to be displayed can be obtained in real time by SurfaceFinger through the Surface instance; after adding the diffuse light intensity and ambient light intensity to the layer data in the FrameBufferObject, call the Media instance to perform rendering and merging and other processing on the layer data with added diffuse light intensity and ambient light, and generate and display the image data.

[0069] In the embodiments of the present disclosure, the user can also set color parameters for the corresponding application or set corresponding color parameters for the entire display screen. At this time, it is necessary to combine the user-defined color parameter α and use the color conversion matrix M*C to process all the layer data in the FBO 0 with added diffuse light intensity and ambient light intensity, and the paper tone display effect with diffuse noise particles based on the user's habit can be obtained as follows:

[0070] result = α*C diffuse *M*C

[0071] Among them, M is the color matrix. The first row determines red, the second row determines green, the third row determines blue, and the fourth row determines transparency. The fifth column is the color offset. The C matrix is the RGBA information contained in the current display area.

[0072]

[0073]

[0074] Process the FBO using the above shader 0 for all layer data in it to obtain the layer texture Texture with diffuse noise particles based on user habits. Finally, draw the FBO corresponding to this Texture 0 and display it through the display screen. It should be noted that the embodiments of the present disclosure also support adding diffuse reflection and custom colors only to the layer data of certain applications. At this time, only the layer data to be displayed of the corresponding application needs to be obtained, added to the FrameBufferObject, and then the diffuse reflection and custom color processing as in the foregoing embodiments can be performed.

[0075] The embodiments of the present disclosure use the diffuse reflection technology to simulate noise particles and perform a layer paper tone processing on the display area. At the same time, the color conversion matrix is used to complete the color customization display. This customization is a color parameter based on user habits, and the Lambert's law of diffuse illumination is used to perform corresponding color adjustment on the display area. Finally, the display area is made as close as possible to the actual effects of ordinary objects such as paper. Compared with the ordinary dark mode, it reduces the stimulation of the screen to the human eye's light source and color, improves the display effect, and provides a better physical experience.
