Abstract
An image compensation circuit for controlling a luminance of a display panel is configured to: receive a plurality of image data; perform gamma tuning to convert the plurality of image data into a plurality of original gamma codes according to a plurality of first compensation values corresponding to a first operation mode; calculate a plurality of gamma difference values between the plurality of first compensation values and a plurality of second compensation values corresponding to a second operation mode; and calculate a plurality of output gamma codes corresponding to the second operation mode according to the plurality of original gamma codes by using the plurality of gamma difference values.
