Prototype single-chip color HDTV broadcasting camera with 8.9M-pixel CMOS image sensor
Details
We developed a prototype single-chip color HDTV camera for broadcasting. This camera used a 1.25-inch 8.9M-pixel CMOS image sensor, and the camera characteristics were; resolution was more than 35% on MTF (45% on square wave response) at 800 TV-lines, the sensitivity was F-stop 11 at 2000 lux with 400% dynamic range and the SNR was 60 dB. In this paper we measured the color reproduction characteristics of the camera. The color difference from conventional 3CCD broadcasting camera depended on the light source and was about 9.3 to 14.5 of the delta-E on a CIELAB color space. Our simulation showed that it was corrected to about 1.8 to 4.5 by the linear-matrix color correction.
