In this paper, a novel architecture suitable for Field Programmable Gate Array (FPGA) implementation of an adaptive color image enhancement based on Hue-Saturation-Value (HSV) color space is presented. The saturation feedback is used in order to enhance contrast and luminance of the color image. The saturation component is enhanced by stretching its dynamic range. Hue is preserved in order to avoid color distortion. The adaptive luminance enhancement is achieved by using a simple arithmetic mean filter. An efficient architecture for histogram equalization is also developed in order to evaluate the performance of proposed algorithm. The algorithm is implemented on Xilinx Vertex II XC2V2000-4ff896 FPGA device. The pipelining and parallel processing techniques have been adapted in order to speed up the enhancement process. The experimental results show that the color images enhanced by the proposed algorithm are clearer, vivid and efficient.
