STV0676

CMOS Digital Camera Co-processor

®

The STV0676 co-processor combined with ST

CMOS image sensors offers highly integrated

imaging products which deliver USB 1.1, RGB-

preview, YCrCb or M-JPEG digital video data at up

to 30 frames per second.

The STV0676 interfaces to CIF (352 x 288) or VGA

(640 x 480) image sensor and performs:

- pixel defect correction,

- auto exposure, auto gain,

- auto white balance, anti-aliasing, anti-flicker,

- colour interpolation, colour balance,

- gamma correction,

- M-JPEG compression.

STV0676 chipsets are supported by a fully-featured

USB driver. This provides a wide range of user

definable settings for optimum camera setup and

operation. Isochronous data transfer over USB

guarantees video quality at all times, irrespective of

the number of other peripherals.

Low power consumption, highly integrated designs

and simple support circuitry enable OEMs to design

low cost, low power, camera products for high

volume consumer market places.

STMicroelectronics offers camera manufacturers

rapid-to-market camera products supported by

comprehensive reference designs, software drivers

and technical backup.
