    "abstract": "An ultrahigh-definition color video camera that uses new 1.25-in. 8M-pixel CMOS digital imagers and diagonal pixel shifting in a 4-pickup system has been developed. The camera head weighs less than 40 kg. A 5× zoom lens and a signal processing system incorporating a function for realtime lateral chromatic aberration correction was also developed. This function makes it possible to suppress optically generated color shifts across the entire zooming range. Moreover, optical-multiplexing transmission equipment and a camera control unit were created. This camera has a limiting resolution of more than 3200 TV lines. The signal-to-noise ratio (SNR) on an HDTV video, which is extracted 1/16 from 8k × 4k pixels video for the reason of SNR measurement device, was about 45 dB. The sensitivity was 2000 lux at F2.8 with a dynamic range of 200%.",
