Development of MPEG camera

Abstract

We have developed a handy digital camera to record MPEG-1 video and JPEG still photo. The newly developed camera signal processing LSI and real-time MPEG-1 codec LSI compress and decompress images, and a RISC MPU, SH-3, does MPEG-1 audio compression and decompression. We adopt PC card type HDD to record compressed image and audio instead of tape media for easy file handling and high adaptability with PC. Users are able to arrange, retrieve and playback files on the camera easily using the 1.8" TFT-LCD and "Media Navigation System", the built-in file handling function.
