摘要：We developed a real-time electronic zoom system that can crop any area in a four-sensor pick-up type Super Hi-Vision (SHV) video and output the area as an HDTV video. The cropped area can be selected using the type of remote control used in a conventional robotic camera system. The maximum zoom ratio is 4X to maintain the HDTV quality. This electronic zoom system enables new program production techniques. For example, an HDTV video of a decisive moment can be cropped from a wide-angle SHV video shot. To evaluate the quality of the cropped image, we examined the resolution, S/N , and chromatic aberrations of generated images. The evaluation results showed that the quality of the cropped HDTV video is good enough for use in HDTV program production.
