IMAGE PROCESSING APPARATUS HAVING A BUFFER MEMORY FOR IMAGE DATA STORAGE

摘要

Two local buffers are provided between an image processing unit and an image compression and expansion unit for compression into a predetermined format. Write and read control units serve to alternately use the two local buffers. As a result, process flow starting from the image processing unit to generate compressed image data by the image compression and expansion unit requires no main memory, whereby high-speed image processing is allowed with low power consumption.
