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

摘要

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