Design and Development of CMOS Image Sensor for Motion Detection & Localization

Active-pixel CMOS image sensors have many attractive features, such as low power consumption, integrated on peripheral circuits, and nondestructive column-parallel readouts. Integrated on signal-processing circuits, they provide the advantages of high-speed parallel operation and lower power consumption, features which meet the special requirements of CMOS image sensors. A number of integrated signal processing circuit sensors have been developed and adopted not only for video but also for machine-vision and security applications as well. However, these approaches almost always involve lowering the pixel density and increasing the chip size to accommodate the added functions requiring large circuits. Hence proposed system is designed to detect a motion on the basis of difference between current and previous frame. While finding the difference system will indicate the location or the position of the motions. System will also capable to detect motion in dark by reducing the infrared filtering from CMOS sensor. The system will then give alert to user through light operating or buzzing the sound.
