DESCRIPTION

· The STV0974 is a low-power digital image processor for the VS6552 color VGA image sensor.

· It delivers high-quality VGA images at up to 30 frames per second.

· Processes sensor data in real-time, including defect correction, color interpolation, sharpness enhancement, noise filtering, cropping, and scaling.

· Supports JPEG compression in real-time.

· Performs sensor housekeeping functions like automatic exposure and white balance controls.

FEATURES

· Supports VS6552 640 x 480 (VGA) color CMOS image sensor.

· VisionLink low EMI link to image sensor.

· Specialized video processor for noise/defect filtering, color reconstruction, sharpness enhancement, and radial corrections.

· Programmable gamma correction for LCD support.

· Programmable cropping, down-sizing, and MMS digital zoom.

· JPEG compression with programmable target file size.

· M-JPEG operation at up to 30 frame/s at VGA resolution.

· Programmable pixel output format including ITU-R 656 modes, RGB viewfinder modes, and JPEG baseline.

· Flashgun control.

· Flexible host interface with 8-bit data /Hsync /Vsync video output and I²C camera control interface.

· 8-bit microprocessor interface with 2 Kbyte video FIFO for JPEG data, 10 Kbyte for non-JPEG data, interrupt, and DMA requests.
