Summary:The invention relates to a tone mapping method and device, computer equipment and a storage medium. The method comprises the steps of determining a target tone mapping algorithm matched with a mapping requirement, and performing data conversion on original image data in a to-be-processed video according to the target tone mapping algorithm to obtain first image data; according to a previous frame image corresponding to the first image data in the to-be-processed video, obtaining a previous frame guide filtering parameter and a previous frame brightness compression parameter corresponding to the previous frame image; performing data processing on the first image data according to the previous frame guide filtering parameter and the previous frame brightness compression parameter to obtain second image data; performing data conversion on the second image data according to a target tone mapping algorithm to obtain target image data; the target image data is used for generating video display content.
