The module is designed to capture high-definition CCD visible, and then transferred video images via USB to a PC in real-time. The system uses OmniVision's OV5640 CCD image sensor as a photoelectric device,and With USB2.0 controller chip CY7C68014A directly connected with the FPGA. Through the FPGA video data from the high-definition CCD module was processed and transferred to the USB chip, and finally displayed on the PC. The design is simple, easy to use, and fitted for large-scale systems. The design and implementation of real-time transmission of high-definition CCD via a USB have been conducted in the handheld products.
