VV5301 & VV6301

®

Mono and Colour QSIF Digital Video CMOS Image Sensors

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.
