Abstract
A video information transfer processing system in which the contents of a video memory are transferred to a main memory device. This system comprises a color extraction circuit including comparison circuits having logical circuits between the video memory and the main memory device and a DMA controller. Each comparison circuit extracts color information to be transferred in response to designated color factor information and the extracted output is supplied to the main memory device. The DMA controller performs timing control, supply of address information and the like in the above-mentioned processing. By using this system, coloring can be carried out during the transference of the video information and a high speed coloring processing is possible.
