ABSTRACT:
The present invention provides an image data processing system to increase the speed of on-screen display (OSD) image processing. The image data processing system comprises M color code registers for storing a plurality of color codes and a first multiplexer electrically connected to every output port of the M color code registers. The first multiplexer comprises a control port for inputting an N-bit image code, and the first multiplexer chooses one of the outputs of the M color code registers as its output according to the N-bit image code. The image data processing system comprises a processor for storing M color codes in the M color code registers and periodically transmitting a plurality of N-bit image codes to the control port of the first multiplexer so that the first multiplexer periodically chooses one of the color codes stored in the M color code registers as its output according to one of the N-bit image codes.
