Abstract
High Dynamic Range (HDR) images capturing, and reproduction have been an essential area to investigate by researchers, especially after the escalating acceleration in computers processing capabilities and the widespread of digital cameras. In this paper, parallel components of HDR algorithm are employed using field programmable gate array (FPGA) to produce HDR image. The implementation involves different pre-processing stages to separate images, color matrices, and then group the similar colors to perform a series of arithmetic operations. In consequence, the algorithm has inherited parallelism to exploit so that the FPGA provides parallel computational speed. The algorithm is implemented using Simulink and ModelSim-Altera MATLAB software to produce the response curve and HDR color components signals. After preforming the tone mapping, the results show that the HDR image provides much greater details and a truer color.
