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
