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.

QSIF resolution sensor
Automatic exposure/gain control
Multiple digital output formats available
I2C interface for sensor control
Integrated 8bit ADC
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.
On board voltage regulator
Automatic Black Calibration
Variable frame rate
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.
Reduced flicker operating modes
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.
