USB VGA Digital Camera Chipset
VV6500 and STV0672
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 ColorMOS^TM 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.
