Ultra small video camera and a video camera system

Image data photographed by a video camera 20 is compressed by a compression and decompression circuit 5, the compressed image data is recorded in an incorporated type semiconductor memory 6 or disk-type memory 13 fixed in the video camera 20 and the recorded image data is transferred to an external recording device 23. Further, the external recording device 23 records the transferred image data in a data storage while it is being compressed. The video camera 20 receives, decompresses and converts into a television signal the compressed image data read by the external recording device 23 in a reproducing operation. A video camera system capable of recording and reproducing long hours of image data by using a video camera having an ultra small size comparable to that of an 8 mm video cassette can be realized by using such a construction.

A video pre/post-processing LSI for video capture

A video processing LSI which converts video signals to digital YUV signals in various image formats was successfully developed for a video capture system. This LSI is suitable for PC cameras, camera/recorders and PC video capture boards.

A flexible scanning system for multi-format video cameras

A flexible pulse generating system for imager scanning was successfully developed. This system is suitable for digital processing video cameras which are controlled by a microcomputer and provides various image formats which are not only NTSC/PAL formats but also some suitable formats for video capture in multimedia use. >
