IMAGE GRADATION IMPROVEMENT APPARATUS WITH COLOR SPACE CONVERTER FORMED IN HARDWARE

摘要

PURPOSE: An image gray increasing apparatus of a hardware color converting apparatus is provided to increase image gray by dithering conversion in a YUV signal area. CONSTITUTION: A YUV dithering unit(420) performs dithering process of a YUV image signal. A color space converting unit(430) receives the YUV image signals which is dithered from the YUV dithering unit. The color space converting unit converts the transmitted YUV image signals into an RGB image signals. An image size controlling unit(440) receives RGB image signals of 24 bit.
