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.
