VV5410 & VV6410
®
Mono and Colour Digital Video CMOS Image Sensors
The VV5410/VV6410 are multi format digital output imaging
devices based on STMicroelectronics’s unique CMOS
sensor technology. Both sensors require minimal support
circuitry.
VV5410 (monochrome) and VV6410 (colourised) produce
digital video output. The video streams from both devices
contain embedded control data that can be used to enable
frame grabbing applications as well as providing input data
for the external exposure controller.
The pixel array in VV6410 is coated with a Bayer colour
pattern. This colourised sensor can interface to a range of
STMicroelectronics co-processors. A chipset comprising
VV6410 and STV0657 will output 8bit YUV or RGB digital
video. A USB camera can be realised by partnering VV6410
with STV0672. Finally a high quality digital stills camera can
be produced by operating VV6410 with STV0680B-001.
Please contact STMicroelectronics for ordering information
on all of these products.
Both VV5410 and VV6410 are initialised in a power saving
mode and must be enabled via I2C control before they can
produce video. The I2C allows the master coprocessor to
reconfigure the device and control exposure and gain
settings.
USB systems are catered for with an ultra low power, pin
driven, suspend mode.
The on board regulator can supply sufficient current drive to
power external components, (e.g. the video coprocessor).
