Abstract:
A pixel signal output from a solid-state imaging device is converted into image data and recorded in a memory by a writing controller. A reading controller reads the image data from the memory by blocks and performs Y/C processing on the image data that has been read out by blocks. A JPEG processing section performs compression coding. The coded data is not recorded in the memory but is written on a recording medium by a DMA processing section.
