1 Function Description
(Note: References to color features do not apply to the OV6130 B&W Digital Image Sensor.)
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, I²C interface, registers, and digital controls that include timing
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.
