A DEVICE FOR PROCESSING IMAGE DATA, ABLE TO CONTROL A RATE OF OUTPUTTING IMAGE FRAMES

摘要

PURPOSE: An image processing device for controlling output speed of an image frame for increasing the speed of the image frame is provided to control the image frame speed and control a synchronization signal. CONSTITUTION: A vertical synchronization signal output unit(740) outputs a vertical synchronization signal. An interface receives column information and row information corresponding to a pixel array. A cycle changing unit(750) uses one or more information and varies the cycle of the vertical synchronization signal. A horizontal synchronization signal output unit(730) outputs the horizontal synchronization signal.
