Abstract
A method for optimizing HDR video display processing, comprises: acquiring original video stream data; decoding the original video stream data to obtain metadata and image frame data of each image frame; in an m-th iteration, for each image frame, according to a characteristic parameter of a target display panel and the metadata, performing HDR processing on the image frame data by using an HDR video display processing algorithm, to obtain the image frame data subjected to HDR processing and corresponds to the original video stream data in the m-th iteration; and according to a playing display detection result, on the target display panel, of the image frame data that has been subjected to HDR processing and is obtained in the m-th iteration, optimizing an algorithm used in an (m+1)th iteration until the optimization of the HDR video display processing algorithm is completed.
