Abstract:Traditional display device couldn’t display HDRI(high dynamic range image) well subject to its dynamic range limitation, and this dynamic range mismatch must be overcome with a reasonable tone mapping method by compressing the dynamic range in order to have better image display quality.This paper summarized current HDRI tone mapping methods.First briefly introduced some concepts of tone mapping method for high dynamic range images.Then,described the classification of tone mapping operators.Based on tone mapping processing methods,introduced three types of tone mapping operators:spatially uniform operator,spatially varying and mixing operators.This paper also described various recent-developed methods and techniques of these operators in details, pointed out the technical advantage of each method and deduced and concluded them. Finally,it described the application areas of this technique and its future developing direction.......
