Abstract

This paper presents a design and hardware implementation of a CMOS sensor based video camera incorporating a module, which combines the functions of automatic white balancing (AWB) and automatic exposure control (AEC). The functionality is achieved using dynamic control of sensor registers using I2C sensor interface. The image data processing is performed using a field programmable gate array (FPGA). The combined AWB/AEC module can be implemented using a gate count of 10k. The results indicate that the implemented video camera produces the desired functionality with good reaction time.
