Abstract: An image processing circuit includes a receiver, at least one memory, a recognition circuit, a calculation circuit and a compensation circuit. The receiver is configured to receive a current image frame and a plurality of previous image frames. The at least one memory is configured to store the plurality of previous image frames. The recognition circuit is configured to select a first previous image frame or a second previous image frame among the plurality of previous image frames from the at least one memory. The calculation circuit is configured to calculate a compensation value for the current image frame according to at least one of the first previous image frame and the second previous image frame by referring to a lookup table (LUT). The compensation circuit is configured to modify a current image data of the current image frame by using the compensation value.

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.
