The dynamic range is a ratio between the maximum and minimum physical measures. Its definition depends on what the dynamic range refers to. For a scene, dynamic range is the ratio between the brightest and darkest parts of the scene. For a camera, dynamic range is the ratio of saturation to noise. More specifically, ratio of the intensity that just saturates the camera to the intensity that jus...

We stand on the threshold of a new era in digital imaging, when image files will encode the color gamut and dynamic range of the original scene, rather than the limited subspace that can be conveniently displayed with 20 year-old monitor technology. In order to accomplish this goal, we need to agree upon a standard encoding for high dynamic range (HDR) image information. Paralleling conventiona...

The dynamic luminance range of many real-world environments exceeds the capabilities of current display technology by several orders of magnitude. Recently, new display systems have demonstrated, which are capable of displaying images with a dynamic luminance range much more similar to that encountered in the real world. The paper summarizes how the human eye perceives high dynamic luminance ra...

High dynamic range (HDR) displays are becoming more common, which has given rise to a number of reverse tone mapping techniques. The goal of these techniques is to expand the dynamic range of all the existing low dynamic range content to t that of these displays. Most of the reverse tone mapping operators, however, fail to o er a good solution in cases where the input images contain large satur...

This paper proposes two efficient residue to binary converters on a new three-moduli set{2^2n-1,2^4n,2^2n+1} using the Chinese Remainder Theorem. The proposed reverseconverters are adder based and memoryless. In comparison with other moduli sets with similardynamic range, the new schemes out-perform the existing schemes in terms of both hardwarecost and relative performance....
