Embodiment 1
[0092] The invention provides an image processing method, such as figure 1 As shown, the image processing method includes:
[0093] 101. Perform color space conversion on an image to be displayed to obtain a converted first image.
[0094] 102. Determine a brightness compensation strategy.
[0095] 103. Acquire brightness change data, and perform brightness compensation on a brightness component in the first image according to the brightness change data in combination with the brightness compensation strategy, to obtain a brightness compensation image.
[0096] 104. Determine a contrast-tone mapping strategy.
[0097] 105. In combination with the contrast-tone mapping strategy, perform contrast-tone compensation on the brightness compensation image to obtain an output brightness image.
[0098] 106. Determine an image transformation matrix according to the output brightness image, and process the image to be displayed according to the image transformation matrix to obtain a...
