IMAGE DATA PROCESSING APPARATUS AND IMAGE DATA PROCESSING METHOD

摘要

A difference data receiving circuit (121) receives differential data of delayed previous image data and present image data from a difference data transmitting circuit (112) and supplies a signal corresponding to the present image data reconstructed on the basis of the differential data to a liquid crystal display panel (122). The difference data receiving circuit (121) includes a line memory (124) for holding image data reconstructed on the basis of the differential data received from the difference data transmitting circuit (112) to delay the image data, and an adding circuit (125) for reconstructing the present image data by adding the previous image data delayed by the line memory (124) to the differential data received from the difference data transmitting circuit (112).
