Abstract
RGB image data outputted from an ADC () is processed in an SPU () and an RPU () and then buffered into a memory () as YUV image data. The YUV image data is outputted from a YUV output unit (), encoded by an image compression and expansion chip (A) and transmitted to a main chip () by a DMAC (). On the other hand, compressed moving image data stored in the memory () is transmitted to the image compression and expansion chip (A) through the control by a DMAC (), decoded therein, then converted into RGB image data in an RGB sampling unit () and inputted to the main chip () by the SPU () through a data line (). With such a construction, it is possible to provide a circuit for compression and expansion, which allows connection with a main processing chip having no YUV input circuit without increasing circuit scale, maintaining general versatility of those circuits.
