Enhanced Single-Chip Processor for USB Camera Applications

The CameraMate processor is a low-cost enhanced single-chip processor for USB PC camera applications. When combined with an OmniVision SVGA, VGA or CIF digital CameraChip sensor, the comprises an integrated USB camera system, with no additional USB transceiver or DRAM required.

The also supports an audio input with for full audio/video operation. During operation, the camera interface synchronizes with the CameraChip sensor's YCbCr 422 progressive video data to perform Downsampling, Clamping and Windowing (DCW) functions with the desired resolution requested by users through the USB command set.

The embedded Data Compression Engine then compresses the video data and the resultant video data is transferred to the host through the USB interface. This standard USB interface allows the end user to implement PC camera systems easily, rapidly reducing the time-to-market.
