A network MPEG camera

A network MPEG camera which can be directly connected to a network for real-time digital video transmission has been developed. The camera works under TCP/IP protocol, and accepts remote control commands from PCs. The command set of the camera includes record/pause command, mode change command, zoom control command, bit rate control command, and so on. The bit rate of MPEG video bit stream can be changed even in the data transmitting and encoding period.

A Digital Video Camera With An Arbitrary Aspect Ratio

A novel video camera with an arbitrary aspect ratio was developed using newly developed digital signal processing VLSIs. Programmable VLSI circuits are adaptively controlled by a microcomputer. With the arbitrary aspect ratio of this digital camera, the proposed wide-screen CCD (charge-coupled device) imager could compete with conventional 3:4 imagers. >

A 9:16 video camera with scene-adaptive intelligent control

As one application of digital camera signal processing, a wide-screen color video camera with a 1/3 in 9:16 charge coupled device (CCD) imager was successfully developed. To get a higher picture quality, exposure and white-balance were adaptively controlled through automatically understanding when and where the camera was used. The camera has full 500-line resolution and can be applied to a wide-screen TV system. >
