In general, the inputted digital images of multiple channels are subjected to compressing and encoding utilizing a correlation between frames for each channel, and the compressed and encoded images are intermittently recorded in a recording medium. Then while a time interval of intermittent recording exceeds a predetermined value, digital images are subject to compressing and encoding in a frame, and are recorded in a recording medium. When compressing and encoding in a frame are performed for digital images, the digital images of multiple channels are recorded in a buffer memory in units of frames.
