Overview
Referring to Figure 1, OV6620/OV6120 CMOS Image
Sensor Block Diagram below, the OV6620 sensor in-
cludes a 356 x 292 resolution image array, an analog
signal processor, dual 8-bit Analog-to-Digital convert-
ers, analog video multiplexer, digital data formatter and
video port, I2C interface and registers, digital controls in-
cluding timing block, exposure, and black and white
balance.
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.
