Overview
The OV6620/OV6120 sensor is a 1/4-inch CMOS imag-
ing device. The sensor contains approximately 101,376
pixels. Its design is based on a field integration read-out
system with line-by-line transfer and an electronic shut-
ter with a synchronous pixel read out scheme. The color
filter of the sensor consists of a primary color RG/GB ar-
ray arranged in line-alternating fashion.
