General Description
The OV6620 (color) and OV6120 (black and white) CMOS Im-
age sensors are single-chip video/imaging camera devices
designed to provide a high level of functionality in a single,
small-footprint package. Both devices incorporate a 352 x 288
image array capable of operating up to 60 frames per second
image capture. Proprietary sensor technology utilizes ad-
vanced algorithms to cancel Fixed Pattern Noise (FPN), elim-
inate smearing, and drastically reduce blooming. All needed
camera functions including exposure control, gamma, gain,
white balance, color matrix, windowing, and more, are pro-
grammable through an I C interface. Both devices can be pro-
grammed to provide image output in either 8-bit or 16-bit
digital formats.
