A display driving circuit includes a frame rate extractor configured to receive a vertical synchronization signal indicating a start of a k-th frame, k-th frame data including information about the k-th frame, and a data enable signal indicating an active period of the k-th frame and a variable blank period that occurs after the active period, and extract a frame rate of the k-th frame, based on the vertical synchronization signal; and an image corrector configured to correct frame data received after reception of the k-th frame data, based on the frame rate of the k-th frame, and output the corrected frame data as output image data, wherein the vertical synchronization signal is received before a start time point of the active period.

In an image data processing device, a selection unit receives a block of original image data of a current image, a block of compressed and reconstructed image data of the current image, and a block of compressed and reconstructed data of a previous image that precedes the current image. A comparison unit compares the block of compressed and reconstructed image data of the current image with the block of compressed and reconstructed data of the previous image. An output unit, in the event that the comparison of the comparison unit results in a match, outputs the block of original image data of the current image as first output data, and, in the event that the comparison of the comparison unit does not result in a match, outputs the block of compressed and reconstructed data of the previous image as the first output data.
