Description

The STV0974 is a low power digital image

processor designed for the VS6552 color VGA

image sensor. The STV0974 uses advanced image

processing techniques to deliver high quality VGA

images at up to 30 frames per second

(frame/s). The sensor data received via the low EMI

sensor interface is processed in real time: this

includes pixel defect correction, color interpolation,

image sharpness enhancement, selective noise

filtering, cropping and scaling, allowing digital zoom

for ViewFinder or MMS applications. Finally the

image can be JPEG-compressed in real-time. The

STV0974 also performs sensor housekeeping

functions such as automatic exposure and white

balance controls.

Applications

■ Mobile phone embedded camera system

■ PDA embedded camera or accessory camera

■ Wireless security camera
