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.
