Abstract
An image processing circuit is configured to generate a first offset value according to second offset values in at least one look-up table corresponding to a starting voltage range of at least one illumination element in a display device. The image processing circuit is further configured to generate output image data according to an ending gray level value and the first offset value. The output image data is for overdriving the at least one illumination element. The second offset values correspond to a starting gray level value of a first frame and the ending gray level value of a second frame.
