Embodiments of the present application provide a video conversion processing method, apparatus, computer-readable medium, and electronic device. The video conversion processing method includes: performing color space mapping processing on the SDR video to be converted and performing mapping processing from pixel values to scene illumination to obtain a first video; detecting a detail loss area in the SDR video, based on the detection of the detail loss area As a result, the expansion coefficient of each pixel in the SDR video is determined; the dynamic range expansion process is performed on the first video based on the expansion coefficient of each pixel to obtain a second video; an HDR video is generated based on the second video . The technical solutions of the embodiments of the present application can improve the visual effect and video quality of the HDR video converted from the SDR video.
Description
technical field [0001] The present application relates to the field of computer and communication technologies, and in particular, to a video conversion processing method, apparatus, computer-readable medium, and electronic device. Background technique [0002] Compared with SDR (Standard Dynamic Range, standard dynamic range image) video, HDR (High-Dynamic Range, high dynamic range image) video can provide more dynamic range and image details, and can better reflect the real environment. Visual effects. In the video processing technology in the field of artificial intelligence, it is necessary to convert SDR video into HDR video, and the conversion scheme from SDR video to HDR video proposed in the related art is difficult to guarantee the quality and visual effect of the converted HDR video. SUMMARY OF THE INVENTION [0003] Embodiments of the present application provide a video conversion processing method, apparatus, computer-readable medium, and electronic device, wh...
