Patent ID: 8693545

Claim:
A display device, comprising: a frame input unit configured to receive a plurality of consecutive frames of image data; a motion vector extractor configured to calculate a plurality of motion vectors based on a difference between image data of a current frame and a previous frame; a motion blur detector configured to determine an area ratio for an area of image data based on the motion vectors, and to determine that motion blur is expected in the area of image data based on the area ratio; and a motion compensator configured to compensate for the expected motion blur in the determined area by inserting black data in the determined area in the current frame data of the determined area, wherein the motion blur detector determines one of a global motion blur, a local motion blur, and a caption motion blur according to the blur area ratio, wherein the motion blur is determined to be a global motion blur if the area ratio is greater than a first threshold, a local motion blur if the area ratio is greater than a second threshold and less than a third threshold, and a caption motion blur if the area ratio is less than a fourth threshold.
