Patent ID: 8085283

Claim:
A data processing apparatus which receives n bit image data and provides revised n-bit image data to a data driver, the data processing apparatus comprising: a frame memory which stores the upper (n−m) bits of n-bit image data of a previous frame; a memory interface which receives n-bit image data of a current frame, outputs the upper (n−m) bits of the image data of the current frame to the frame memory, receives the upper (n−m) bits of the image data of the previous frame from the frame memory and outputs n-bit revision data including the upper (n−m) bits of the image data of the previous frame and lower m-bit fixed data corresponding to a decimal value 1; a first reviser which revises a color temperature of the n-bit image data of the current frame, the first reviser receiving the n-bit image data of the current frame and the n-bit revision data and generating first revision image data of the current frame; and a second reviser which revises a gray scale of the image data of the current frame, the second reviser receiving the first revision image data of the current frame from the first reviser and the n-bit revision data, and the second reviser outputting n-bit revised image data of the current frame.
