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 VV6410/VV6500 are ColorMOSTM digital CMOS sensors that deliver outstanding picture quality. These CIF/VGA resolution sensors have been created specifically to meet the standards required for personal video communications. Both sensors feature automatic black and dark level calibration to ensure optimum image quality.

The STV0672 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, which performs automatic exposure, automatic gain control and automatic white balance, together with colour matrixing, gamma correction, peaking, automatic defect correction and noise cancellation logic. This data is then compressed to deliver high frame rates with minimum impact on image quality. The USB interface supports USB isochronous data transfer mode. This data transfer mode allows the user to specifiy the percentage of USB bandwidth to allocate to a USB device, thus allowing multiple cameras/other USB peripherals to be connected to a single USB hub. 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.
