USB CIF/VGA Digital Camera Chipset

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.
