STV0674
Tri-mode CMOS digital camera co-processor
Description
The STV0674 is a flexible, scalable digital camera
co-processor for use with the range of CMOS
imaging sensor products from STMicroelectronics.
The same chipset can be used for a wide range of
digital imaging products with unique features and
price/performance points.
The STV0674 is designed for use with CIF
(352x288) or VGA (640x480) ST CMOS image
sensors and provides full exposure control, color
processing and mode control for these sensors.
The STV0674 can be used to implement any of the
following products:
Low cost USB Webcam Camera - a two-chip
solution providing up to 30 frames per second VGA
simultaneous video and audio capture.
Dual-Mode Camera - USB webcam and CIF or
VGA digital still camera in a single product.
Tri-Mode Camera - USB webcam and digital still
camera with the addition of a ‘camcorder’ mode to
allow simultaneous video and audio capture directly
to external memory for later upload to the PC.
