Chip-Based Design for Real-Time Moving Object Detection Using a Digital Camera Module

Digital cameras have been a popular candidate device employed in visual sensing applications. Its attractive features, including wide detection range, high resolution, and reliable performance, have made the digital camera an indispensable sensor in surveillance and machine vision systems. In this paper, we propose an implementation of real-time motion detection using a fully digital integrated circuit design approach. This system is foreshadowed in the future as an essential venue for the class of miniaturized motion sensing systems. By comparing to the traditional counterparts, our system is immune from common computation dilemmas for real-time processing. The proposed one-page-comparison (OPC) mechanism also contributes to the reduction of the memory and logic gates used in a field programmable gate array (FPGA) chip. Satisfactory performances are obtained in real-life test scenarios using this approach, which complements the requirement for a high resolution digital camera equipped in the motion detection system.
