Abstract: Systems and methods of rendering DCI-compliant image data on Enhanced Dynamic Range (EDR) display systems are disclosed. One embodiment of an EDR projector system comprises a first modulator and a second modulator. One method for rendering DCI-compliant image data on an EDR projector system comprises: receiving input image data, said image data comprising a plurality of image formats; determining whether the input image data comprises DCI image data; if the input image data comprises DCI image data, then performing dynamic range (DR) processing on the DCI image data; and rendering the dynamic range processed DCI image data on the EDR projector system. One DR processing method is to set the first modulator to a desired luminance level—e.g., fully ON or a ratio of DCI max luminance to the EDR max luminance. In addition, a desired minimum level of luminance may be set for the EDR projector.

Abstract: Systems and methods for automatically optimizing pairs of stereo images are presented. Pixels in an image pair are reprojected from their raw format to a common pixel-space coordinate system. The image pair is masked to remove pixels that do not appear in both images. Each image undergoes a local enhancement process. The local enhancements are processed into a global enhancement for each image of the image pair. A factor is calculated to balance the left and right images with each other. A brightness factor for the image pair is calculated. The enhancements, including the balancing and brightness factors, are then mapped to their respective images.

Abstract: The automatic video comparison system for measuring the quality of decoded data described herein provides a method for measuring the quality of decoded data at the level of sub-units of a unit of data, for instance at the level of sub-blocks of a video frame.
