METHOD OF REALIZING COMBINATION OF MULTI-SETS OF MULTIPLE DIGITAL IMAGES AND BUS INTERFACE TECHNIQUE

摘要

The invention relates to a bus interface technique and a method of realising combination of multi-sets of multiple digital images. It mainly comprises an image-processing unit for M-channel sub-images, an image-processing unit for a N-set of combined images, a N-set of video data buses, address and control buses, pixel data read control and bus switching logic module. Controlled by the gate output-signals of the M-route sub-images pixel data, the M-channel sub-images pixel data are output onto a predetermined one of the N-sets of the video data buses in determined time. The sub-image pixel data on the N sets of the video data buses are combined to N sets of combined images by the N-sets of image combined modules respectively, and the complete combined video data are output from the N sets of the combined image channels. The invention can increase the system capability of processing multi-image services in application to the multimedia image communication systems and other image editing systems.
