In the description of the present application, it is noted that, unless explicitly stated or limited otherwise, "including" and "having" and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art. Further, in the description of the present application, "a plurality" means two or more unless otherwise specified. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
The screen color gamut adjusting method provided by the embodiment of the application can be realized by depending on a computer program, and can run on a screen color gamut adjusting device based on a von neumann system. The computer program may be integrated into the application or may run as a separate tool-like application. The screen color gamut adjusting device in the embodiment of the application can be a display device with a display function, such as a television, a mobile phone, a personal computer, a tablet computer, a handheld device, a vehicle-mounted device, a wearable device, and the like, and can also be a module for realizing the screen color gamut adjusting method in the display device. Please refer to fig. 1, which provides a schematic structural diagram of a screen color gamut adjusting device according to an embodiment of the present disclosure, where the screen color gamut adjusting device includes a processor, a display screen, and a color gamut adjusting module, one end of the color gamut adjusting module is connected to the processor, and the other end of the color gamut adjusting module is connected to the display screen. The user can select the corresponding color intensity type on the screen color gamut adjusting device on the display equipment according to the eyesight condition of the user, and the processor can receive the target color intensity type input by the user and can acquire the color adjusting matrix corresponding to the target color intensity type. The user or related staff can save the color adjustment matrix corresponding to different color weakness types in the processor in advance, and it can be understood that the range of the color gamut visible by the color weakness people is smaller than that of the color gamut visible by the color weakness people, and similarly, the initial color gamut of the screen color gamut adjusting device, namely, the color gamut which can be displayed by the screen color gamut adjusting device is also larger than that of the color gamut visible by the color weakness people, so that the color gamut of the screen color gamut adjusting device needs to be adjusted to be the range of the color gamut visible by the color weakness people. Therefore, the processor can obtain a target color gamut corresponding to the target color intensity type, wherein the target color gamut is a color gamut range visible for people of the target color intensity type.

It can be understood that the colors displayed by the screen color gamut adjusting apparatus are not completely accurate, and the initial red point, the initial green point and the initial blue point in the initial color gamut have color coordinates and differences from the real red point, the real green point and the real blue point, but we can determine the initial color gamut by the initial red point, the initial green point and the initial blue point, the initial color gamut is a triangle formed by connecting the initial red point, the initial green point and the initial blue point two by two in the color space, and similarly, the target color gamut is a triangle formed by connecting the target red point, the target green point and the target blue point two by two in the color space. For example, FIG. 2 is a CIE1931 color space, point R 1 、B 1 And G 1 An initial red point, an initial green point and an initial blue point respectively representing an initial color gamut, and R 1 、B 1 And G 1 The triangle formed by connecting two by two is the initial color gamut; point R 2 、B 2 And G 2 A target red color point, a target green color point and a target blue color point, respectively, representing a target color gamut, and a point R 2 、B 2 And G 2 The triangle formed by connecting two by two is the target color gamut.

When the processor receives an input target color intensity type, a color adjustment matrix corresponding to the target color intensity type can be found, color gamut adjustment information is generated based on the color adjustment matrix, the processor transmits the color gamut adjustment information to the color gamut adjustment module, the color gamut adjustment module can adjust the color of each pixel point in the screen display content according to the color adjustment matrix contained in the color gamut adjustment information, if the color gamut adjustment is not performed, the first color of each pixel point can be displayed on the display screen, the first color exists in the initial color gamut but does not necessarily exist in the target color gamut, but after the color gamut adjustment module receives the color gamut adjustment information, the color gamut adjustment module can obtain a second color of the first color in the color space according to the first color and the color adjustment matrix, and the second color exists in the target color gamut. The color gamut adjusting module can generate a first color matrix according to a first color coordinate of a first color in a color space, and then calculate to obtain a second color matrix based on the first color matrix and the color adjusting matrix, wherein a result obtained by multiplying the color adjusting matrix and the second color matrix is the first color matrix, and the color gamut adjusting module obtains a second color coordinate corresponding to the second color matrix and finds a second color in the color space according to the second color coordinate. Then the color gamut adjusting module transmits the second color to the display screen, and the display screen can display each pixel point in the screen display content based on the second color.

Alternatively, the processor 110 may be implemented in hardware using at least one of Digital Signal Processing (DSP), field-programmable gate Array (FPGA), and Programmable Logic Array (PLA). The processor 110 may integrate one or a combination of a Central Processing Unit (CPU), a Graphics Processing Unit (GPU), a modem, and the like. The CPU mainly processes an operating system, a user page, an application program and the like; the GPU is used for rendering and drawing display content; the modem is used to handle wireless communications. It is understood that the modem may not be integrated into the processor 110, but may be implemented by a communication chip.
