This paper presents a low power motion detection camera processor, called Bluebox. It includes an ARM embedded microprocessor and several hardwired modules using pseudo Advanced Microprocessor Bus Architecture (AMBA). For reducing power consumption, we use simple, but very efficient software and hardware techniques. We propose a new motion detection algorithm to use only one bit per pixel without loss of accuracy, and therefore it needs very small computing power and satisfies real-time processing requirements. And we design a power management scheme to control system clocks for power reduction. Our proposed architecture is implemented and verified in an FPGA with a CIS (CMOS Image Sensor). The proposed architecture can be easily applied to many areas, for example, a potable battery operated surveillance application.
