Abstract: Image acquisition system consists of four major components: CMOS circuit cameras, camera cache control logic, SRAM memory and embedded system bus interface. Wireless sensor network is composed of numerous tiny sensor nodes which are randomly laid in a specific detection area consisting of self-organizing networks. The paper presents development CMOS sensor image acquisition system based on Wireless sensor networks and develops image acquisition system works by sending the correct timing signal for CPLD to CMOS image sensor, drive their normal work to take the appropriate shutter mode, and the collected image data manipulation packages, output to the USB chip, then the incoming image data transmission chip host. Experimental results show that the designs of the image sensor drive timing to meet the image requirements.


Keywords: Wireless sensor network, CMOS, Image Acquisition, Image Sensor.
