1/4-inch, VGA-format, CMOS image sensor

摘要

Because of its low power consumption, single low-voltage drive, and on-chip timing control function, the development of the CMOS image sensor has attracted considerable attention. This sensor's capabilities make it possible to fabricate a verysmall camera system that can be applied to mobile computers, TV phones, PC cameras, and so on.Two difficult problems were encountered in relation to the CMOS image sensor: fixed pattern noise, and pixel size shrinkage. We have overcome these problems and succeeded in developing the 1/4-inch, VGA-format, CMOS image sensor.
