Design of FPGA Based CMOS Camera for Embedded Systems

Nowadays, usage of CMOS camera becomes worldwide. CMOS cameras draw much less power than CCDs. CMOS sensors, use the same manufacturing technologies as microprocessors and memory modules, thus they are easier to produce and are low-cost. In this paper, we implement a FPGA based CMOS camera with 6.6 mega pixel resolution for implementing image processing algorithms. The main property of this camera is that, it has a simple Actel series FPGA without using RAM for image processing. This system can control its power consumption with an on board control power circuit and is usable in space applications. The experimental results show that the system can capture images at the rate of 1frame/s when the frame size of CMOS digital camera is set to 2012*3002 pixels, which can meet the special image acquisition requirements
