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.
Full USB support (v1.1)including two selectable default hardwired video/audio descriptors as well as options for additional customer specific USB PIDs.
High-performance video transfer rate of up to 20 fps for SVGA and up to 30 fps for VGA,CIF/SIF and QCIF/QSIF formats with selectable YUV 4:2:2 or 4:2:0 formatting.
Full USB audio interface (Class 1.0 compliance) incorporating a 16-bit mono ADC for microphone usage with sampling rates of 8 KHz, 16 KHz, and 24 KHz.
Low voltage 2.5V (Core) and 3.3V (I/O) operation
8-bit 8051-compatible microcontroller, with embedded 512-byte RAM
|| External system clock or independent crystal operation
YUV averaging and Y distribution with Y enhancement
Defect compensation up to 8 pixels in YUV input
