According to the method described in the above embodiments, examples are described in further detail below.
In this embodiment, the data processing apparatus is specifically integrated in a computer device, where the computer device is a server, and the computer device may also be a terminal.
First, it should be noted that in the related art, when a display device such as an LCD display screen or an LCD television displays an image, there is an uneven image display. In order to solve the problem of uneven display of an image, the existing related art compensates the display difference of the image to a certain extent, and the existing related art adopts a compensation mode that the amplitude and gain of the R/G/B signal of the image are directly adjusted, for example, the corresponding R/G/B signal is attenuated for the bright area of the image, and the corresponding R/G/B signal is enhanced for the dark area of the image, so that the brightness difference is eliminated or reduced.
However, this approach of the related art has many drawbacks: (1) The image quality is affected, and when the amplitude and gain of the R/G/B signal of the image are increased, high-order saturation is caused, so that the bright details of the image are lost; when the amplitude and gain of R/G/B signals of the image are reduced, the gray resolution of the image is reduced, so that the brightness level and transition of the image are poor; (2) When the amplitude and gain of the R/G/B signal are reduced, the brightness displayed by the image is reduced, but the backlight power consumption of the display device is still unchanged, so that the light efficiency/energy efficiency is reduced; (3) In the prior art, display devices are required to have high brightness. The related art may cause a decrease in the maximum brightness of the display device, for example, decrease in R/G/B signals for a region where an image is bright, which may cause a decrease in the maximum display brightness, which may cause a bad experience to a user.
