High dynamic range image processing technology

Abstract

High dynamic range images can be used to capture real environments through digital equipment, and images with high dynamic range are synthesized through specific algorithms in the obtained image information. In the process of image capture, due to the performance of digital equipment, there will be noise in the captured image, which will affect the quality of the image during synthesis. It is necessary to reduce the noise in the image and then synthesize a high dynamic range image. Due to the low dynamic range of traditional display devices, high dynamic range images cannot be directly displayed on traditional devices, and the high dynamic range images are mapped to the dynamic range of the display for display by a method of color scale mapping. Therefore, this paper mainly studies the methods of high dynamic range image synthesis and color scale mapping
