VISION & IMAGING

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.

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.
