Color Space Conversion from RGB to YCbCr based on FPGA

Abstract

In image processing, color space conversion of RGB-YCbCr is often used. Based on ITU-T T.871 design standard and FPGA operation characteristics, this paper realizes the color space conversion from RGB to YCbCr using Verilog language. In the FPGA chip, the multiplier resources are very scarce. The optimization of multiplier resources and processing speed is often the bottleneck of image processing. In traditional methods, 5-9 multipliers are usually used. By optimizing the formula, compared with the results of other documents, this module only uses 4 multipliers, so the resource consumption is less. The pipeline design is used, the operation speed is fast, and the real-time performance is good. It is suitable for the requirement of JPEG compression and is easy to be realized in the actual project.
