Design And Implementation Of Low Power Smart Motion Detection Using CMOS Sensor
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.
In market-driven applications such as surveillance, automotive, and machine vision, there is an increased demand for
imaging systems with real-time processing capabilities. In some cases, these specific requirements are quite hard to be
fulfilled through a conventional approach, consisting of a standard charge-coupled device or complementary metal–oxide–
semiconductor (CMOS) camera linked to a digital signal-processing platform. These systems are typically based on general
purpose architectures, performing real-time image processing. Although their high computational power and high flexibility
are satisfactory for many applications, there are some low-level images processing tasks that can be efficiently executed
using ad-hoc image processing capabilities embedded directly in the imager. Thanks to the great advantages of CMOS sub
micrometer technology, allowing even smaller device feature size, some recent CMOS image sensors with integrated signal
processing have been developed, following two main approaches: pixel-level and array-level processing.
