ABSTRACT:
CCD data is compressed by compression means and stored in a raw image data buffer (step10). Then, the compressed data is expanded by expansion means, so that pixel data thereof is sequentially output to an RPU (step11). The RPU executes real-time image processing on the pixel data, so that the processed data is stored in a processed data buffer in units of frames. Then, a CPU reads an image from the processed data buffer at a proper timing and performs software processing such as high-efficiency coding through a temporary storage data buffer, for storing and preserving the processed data in a storage medium (step12). Thus provided is an image processing circuit capable of reducing the scale of buffer areas in a memory for remarkably reducing the cost for the memory as well as power consumption.
