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

Takuya Imaide; Tomoyuki Kurashige; Yasushi Takagi; Hiroyuki Tarumizu

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. >
