[0028] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0029] The following is a detailed description with reference to the accompanying drawings.

[0030] First, see Figure 1 To describe an electronic device used to implement the blue light filtering method and / or blue light filtering device 10 of the embodiment of the present application.

[0031] The blue light filtering method and / or the blue light filtering device 10 may be implemented in the form of a computer readable instruction. The computer readable instruction may be in the form of a computer readable instruction. Figure 1 The electronic device shown is running.

[0032] An electronic device provided in an embodiment of the present application includes a memory, a processor, and computer-readable instructions stored in the memory and executable on the processor. When the processor executes the program, a blue light filtering method is implemented.

[0033] Figure 1 FIG. 1 is a schematic diagram of the internal structure of an electronic device according to an embodiment of the present application. The electronic device may be a server. Figure 1 The electronic device includes a processor, a non-volatile storage medium, an internal memory, an input device, a display screen, and a network interface connected via a system bus. The non-volatile storage medium of the electronic device can store an operating system and computer-readable instructions. When the computer-readable instructions are executed, the processor can execute a blue light filtering method of each embodiment of the present application. The specific implementation process of the method can be referred to Figure 2 The specific content is not repeated here. The processor of the electronic device is used to provide computing and control capabilities to support the operation of the entire electronic device. The internal memory may store computer-readable instructions, which, when executed by the processor, may enable the processor to execute a blue light filtering method. The input device of the electronic device is used to input various parameters, the display screen of the electronic device is used for display, and the network interface of the electronic device is used for network communication. Those skilled in the art can understand that Figure 1 The structure shown in the figure is merely a block diagram of a partial structure related to the scheme of the present application, and does not constitute a limitation on the electronic device to which the scheme of the present application is applied. The specific electronic device may include more or fewer components than shown in the figure, or combine certain components, or have a different arrangement of components.

[0034] See also Figure 2 An embodiment of the present application provides a blue light filtering method, which may include the following steps.

[0035] Step S11, obtaining a preset blue light filtering value.

[0036] In this embodiment, the preset blue light filter value can be manually set by the user in advance, or can be predetermined by reading the parameters of other blue light filter software. It should be noted that the blue light filter value setting range is 0 to 100, and the specific value can be adjusted according to the usage scenario, which will not be further described here.

[0037] Step S12, determining blue light filter layer parameters based on the blue light filter value and a preset color balance formula.

[0038] The preset color balance formula is as follows:

[0039]

[0040] Among them, FilterMask(a, R, G, B) represents the blue light filter layer parameters, a represents the transparency of the blue light filter layer, blueFilter represents the blue light filter value, R represents the red brightness level of the blue light filter layer, G represents the green brightness level of the blue light filter layer, B represents the blue brightness level of the blue light filter layer, R represents the blue brightness level of the blue light filter layer k Indicates the preset red filter adjustment parameter, S k Indicates the preset non-blue filter parameters, G k Indicates the preset blue filter adjustment parameters. Indicates the floor symbol.

[0041] It can be understood that the color mode of the displayed image is mostly selected to display in RGB mode, where R represents red, G represents green, and B represents blue. That is, the composition of various colors of the displayed image is a mixture of RGB in different proportions. After setting the blue light filter value, the displayed color of the displayed image will be deviated. The preset color balance formula can reduce the display color deviation problem of the displayed image.

[0042] Furthermore, the transparency of the blue light filter layer is calculated by using the preset blue light filter value, and the red brightness level and green brightness level of the blue light filter layer are adjusted using the transparency of the blue light filter layer, so that the blue light filter layer can reduce the color deviation problem caused by blue light filtering to a certain extent.

[0043] It should be noted that R k , S k , G kThe three parameters can be adjusted according to the application scenario to minimize the display color deviation of the displayed image.

[0044] Step S13: performing blue light filtering on the image to be displayed based on the blue light filter layer parameters.

[0045] In one embodiment, a blue light filter layer may be generated according to the blue light filter layer parameters; and the blue light filter layer may be covered on the image to be displayed to implement blue light filtering of the image to be displayed.

[0046] Specifically, the blue light filter layer parameters can be used to generate a blue light filter layer, which can be a top floating window with a transparent background color, and the top floating window covers the image to be displayed. It can be understood that the top floating window is similar to a transparent film with a background color. By covering the top floating window on the image to be displayed, the image to be displayed is output through the top floating window, which can reduce the intensity of the blue light component in the image to be displayed and reduce the color deviation problem caused by blue light filtering.

[0047] In another embodiment, the pixel value of each pixel of the image to be displayed may be adjusted based on the blue light filter layer parameter.

[0048] Specifically, the adjustment process can be implemented in a display driver, which can apply the blue light filtering method in the present application and use the blue light filtering layer parameters to adjust the pixel value of each frame of the image to be displayed, so that the blue light component in the adjusted image to be displayed is reduced, and the color deviation problem caused by blue light filtering is reduced.

[0049] Furthermore, the adjustment process can also be implemented in the logic board of the display. When refreshing each frame of the image to be displayed, the logic board uses the blue light filter layer parameters to adjust the image to be displayed, so that the image to be displayed output through the logic board reduces blue light and color deviation at the same time.

[0050] Furthermore, the blue light filtering layer parameters can be used to filter the blue light of the image to be displayed according to the following formula, and the specific formula is as follows:

[0051]

[0052] Among them, D o (R, G, B) represents the color brightness level of the image to be displayed after image processing, D i represents the original image color brightness level of the image to be displayed, FilterMask(R, G, B) represents the color brightness level of the blue light filter layer, a represents the transparency of the blue light filter layer, Indicates the floor symbol.

[0053] It can be understood that the image to be displayed can be pre-stored or collected in real time. As for how to obtain the image to be displayed, it is a common technical means for those skilled in the art and will not be described here.

[0054] The present application does not limit the type of images to be displayed.

[0055] Specifically, in one embodiment, the image to be displayed may be an image that has not been processed by blue light filtering, and in another embodiment, the image to be displayed may be an image that has been processed by blue light filtering.

The determination module 200 is used to determine the blue light filter layer parameter based on the blue light filter value and a preset color balance formula. The filtering module 300 is used to perform blue light filtering on the image to be displayed based on the blue light filter layer parameter.

[0058] In the embodiment of the present application, the determination module 200 is further used to determine the blue light filter layer parameter by the following formula:

[0059]

[0060] Wherein, FilterMask(a, R, G, B) represents the parameters of the blue light filter layer, a represents the transparency of the blue light filter layer, R represents the red brightness level of the blue light filter layer, G represents the green brightness level of the blue light filter layer, B represents the blue brightness level of the blue light filter layer, R represents the red brightness level of the blue light filter layer, k Indicates the preset red filter adjustment parameter, S k Indicates the preset non-blue filter parameters, G k Indicates the preset blue filter adjustment parameters. Indicates the floor symbol.

[0061] In the embodiment of the present application, the filtering module 300 is further used to generate a blue light filter layer according to the blue light filter layer parameters; and to cover the blue light filter layer on the image to be displayed to achieve blue light filtering of the image to be displayed.

[0062] In the embodiment of the present application, the filtering module 300 is further used to adjust the pixel value of each pixel of the image to be displayed based on the blue light filtering layer parameter to achieve blue light filtering of the image to be displayed.
