Paper Abstract

We have developed a 60 frame/sec 2 K multiplied by 2 K progressive-scan color camera system. Two new key technologies have been applied in the design process. One is high-data- rate imager operation technology in which each of four charge modulation device (CMD) chips is driven at 167 M pixel/sec in progressive scan mode. One chip consists of 1920 (H) multiplied by 1035 (V) pixels. The other technology is the four-imager pickup method in which two CMD imagers are used for green and the other two for red and blue. Spatial offset imaging is applied in the vertical direction to the two green imagers so that the equivalent number of vertical lines reaches 2070, twice that of one CMD. The above technologies enable the construction of a very-high-resolution camera with a data rate of 334 M pixel/sec and a vertical limiting resolution on a color monitor of more than 1500 lines.
