Abstract
A digital camera includes an SDRAM. The camera data taken is first written on a camera data area formed in the-SDRAM, and thereafter read out 8 lines a time. This 8-lines camera data is YUV-converted by a signal precessing circuit. The resulting 8-lines YUV data is stored in a work area of the SDRAM. A JPEG CODEC reads the YUV data block by block out of the work area, and compresses it. The compressed data is written block by block over the camera data area. At this time, the compressed data is written over in a manner. avoiding camera data uncompleted of compression. Such a process is repeated very 8 lines. If compressed data is obtained for all of the camera data stored within the camera data area, the compressed data is recorded at one time into a flash memory.
