We have developed a 2K×2K progressive scan color camera system. In the design process, two new key-technologies have been applied. One is the sensor operation technology at high rate. In the system, four chips of CMD (Charge Modulation Device) with 1920 (H)x1035 (V) pixel are driven at 167M pixel/sec in progressive scan mode respectively. The other technology is the four sensors pickup method in which two sensors are used for green and the rests are for red and blue. The spatial offset imaging method in the vertical direction has been applied to the two green sensors. Equivalently the number of vertical lines of green channel increases to 2070 lines which is equal to the twice number of lines in the CMD. By these technologies, the ultra high definition camera having the data rate of 334MHz pixel/sec has been realized and we are sure that the vertical limiting resolution is achieved to more than 1600TVL on a color monitor.
