Description
The STV0684 processor is targeted for use in
CMOS digital still cameras. ST supplies complete
camera reference designs which include sensor,
co-processor, firmware and software drivers. The
STV0684 uses a small BGA package (12 mm x 12
mm) ideal for the design of very small digital
cameras. The STV0684 incorporates ST’s unique
and highly performing video processor algorithms
including newly improved and patented algorithms
(e.g. NORA and Anti-vignetting).
The CMOS sensors from STMicroelectronics use
pinned photodiodes manufactured in a high
performance process resulting in improved low light
performance, reducing the gap with CCD sensors.
Applications
●
Digital still cameras
●
Solid state video camera recorders
●
Embedded cameras
