The USB camera chipsets from STMicroelectronics are at the heart of a variety of products which have proven to be highly successful in a demanding marketplace. Supported by comprehensive reference designs, technical backup and fully-featured software drivers, STMicroelectronics offers camera manufacturers the opportunity to benefit from rapid time to market with a product of proven quality.
The VV6500 is a ColorMOSTM digital CMOS sensor that delivers outstanding picture quality. This VGA-resolution sensor has been created specifically to meet the standards required for high quality personal video communications.
This sensor features automatic black and dark level calibration to ensure optimum image quality.
The STV0672 (CPIA2) co-processor receives image data from the sensor, that is processed, compressed and passed to the USB port. It incorporates a digital video processor engine to perform automatic exposure, automatic gain control and automatic white balance, together with colour matrixing, gamma correction, aperture correction, automatic defect correction and noise cancellation logic. This data is passed to the proprietary video compression that delivers high frame rates with minimum impact on image quality. The USB interface supports USB isochronous data transfer mode, ensuring access to guaranteed bandwidth at all time, irrespective of how many peripherals are then added.
The chipset is backed by a fully-featured driver which provides a host of user-definable settings for optimum camera setup. The user interface supports a degree of customisation.
STMicroelectronics offers a range of support services to guarantee product quality, including test specifications and test software.
