Research on Video Information Acquisition Module of OV7620
In order to meet real-time and quick requirements for video information acquiring and processing, this paper introduces a hardware platform based on Altera's Cyclone series EP1C12Q240C8, to descript the driving timing for CMOS image sensor OV7620 with Verilog HDL language to acquire video information. The system uses SCCB programming model, establishes communication between FPGA chip and CMOS image sensor to achieve the control and acquisition of the signal. In order to achieve operational requirements in different environments and needs, the corresponding registers and the controller are set within CMOS image sensor. Experimental results show that the control of the CMOS image sensor OV7620 flexibly provides a stable and reliable source of raw information for video monitor, industrial applications such as on-site monitoring.
