Encoding, decoding, and representing high dynamic range images
TL;DR: In this article, a tone mapped image with HDR reconstruction data in the form of luminance ratios and color residual values is encoded and decoded to generate a restored HDR image free of the color alterations.

TL;DR: This work proposes a technique for displaying three-dimensional imagery of general scenes with nearly correct focus cues on multi-plane displays by using a model of defocus in the eye of the viewer, and uses an optimization algorithm to compute the images to be displayed on the presentation planes.

Electronic camera having multiple sensors for capturing high dynamic range images and related methods
TL;DR: In this paper, the authors present a controller for controlling the shutter and the readout circuitry of an electronic camera consisting of a processor and a memory having computer-readable code embodied therein which, when executed by the processor, causes the controller to open the shutter for an image capture period to allow the two or more image sensor arrays to capture pixel data.
Patent
Method and apparatus for image data transformation
TL;DR: In this article, a sigmoidal transfer function is used to control min-tone contrast in the image data for display on a target display in a way that substantially preserves the creative intent embodied in the original image data.
