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
