Abstract
An image processing method with auto-adjusting gamma value is provided. This image processing method includes: receiving a detected value dependent upon a view angle between a normal direction of a screen and a sight direction of a viewer to the screen; receiving an original video frame with a plurality of pixels; determining at least one gamma table to obtain a gamma value for a pixel of the plurality of pixels according to the detected value, wherein there is an original pixel value corresponding to the pixel; and generating and outputting a corrected pixel value of the pixel based on the gamma value and the original pixel value of the pixel, wherein the screen is configured to show a corrected video frame having the pixel with the corrected pixel value. An image processing assembly and an image processing system are also provided.
