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. [...] Key Method 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.Expand
