Mono and Colour QSIF Digital Video CMOS Image Sensors

VV5301 & VV6301
Commercial in confidence
The VV5301 and VV6301 are highly integrated digital
output imaging devices based on STMicroelectronics’s
unique CMOS sensor technology. Both of these sensors
require minimal support circuitry and provide an ideal low
cost imaging solution.
VV5301 (monochrome) and VV6301 (colourised) produce
digital video output. The video streams from both devices
contain embedded control data that can be used to enable
frame grabbing applications.
The pixel array of the VV6301 has colour filters forming a
Bayer colour pattern. This sensor requires software to
perform colour processing to allow an image to be
displayed on a PC.
The sensor can perform automatic black calibration to
remove voltage offsets in the video signal path that lead to
offsets in the output image. These offsets are removed
using 2 Digital to Analogue Convertors (DACs). The
automatic black calibration algorithm monitors the average
level of the sensor black pixels and adjusts the input level
to the 2 DACs to remove the offset.
A 2 wire serial interface allows the sensor to be
reconfigured if required.
