®
CMOS Digital Camera Co-processor
The STV0676 co-processor bined with ST CMOS image sensors offers highly integrated imaging products which deliver USB 1.1, RGBpreview, YCr Cb 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 pression. 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 prehensive reference designs, software drivers and technical backup.
