1.1

Overview

Referring to Figure 2 below, the OV6630 sensor includes a 356 x 292

resolution image array, an analog signal processor, dual 8-bit A/D

converters, analog video multiplexer, digital data formatter, video

port, I

block, exposure control, black level control, and white balance.

The OV6630/OV6130 sensor is a ¼ inch CMOS imaging 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 shutter with a synchronous pixel read out scheme. The

color filter of the sensor consists of a primary color RG/GB array

arranged in line-alternating fashion.
