Patent ID: RE42286

Claim:
An image data processing system comprising: 2N 2 N color code registers for storing a plurality of color codes; a first multiplexer electrically connected to every output port of the 2N 2 N color code registers, the first multiplexer comprising a control port for inputting an N-bit image code, the first multiplexer choosing one of the outputs of the M color code registers as output according to the N-bit image code; a processor for storing 2N 2 N color codes in the 2N 2 N 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 2N 2 N color code registers as output according to one of the N-bit image codes: an image memory electrically connected to an output port of the first multiplexer for storing a plurality of color codes received from the first multiplexer; an address controller electrically connected to both the processor and the image memory for storing the plurality of color codes received from the first multiplexer into a predetermined address of the image memory according to a command from the processor; a display connected to an output port of the image memory; and a display controller electrically connected to both the display and the address controller for transmitting the plurality of color codes stored in the image memory to the display via the address controller, and for controlling operations of the display so that the display is able to show a first image according to the plurality of color codes.
