A CMOS image sensor (CIS) with low power motion detection for security camera applications

Abstract

This paper presents a low power motion detection algorithm and system architecture. The proposed architecture uses just one bit data of each selected pixel for motion detection, where less than a few percentages of the total pixels will be used. Since only a small amount of image data is used for the motion detection, extremely low power consumption is possible. This architecture is useful for portable battery-operated security cameras.
