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
