摘要： Various implementations address high dynamic range ("HDR") images. In one particular implementation, a low dynamic range ("LDR") image is generated from an HDR image, and information is generated allowing the HDR image to be reconstructed from the LDR image. The LDR image and the information are encoded. In another implementation, a signal or signal structure includes an LDR section including the encoded LDR image, and an information section including the encoded information. In another implementation, the encoded LDR image and the encoded information are both decoded. The HDR image is then reconstructed based on the decoded LDR image and the decoded information.

摘要： A new high dynamic range (HDR) image synthesis which can handle the local object motion, wherein an interactive graphical user interface is provided for the end user, through which one can specify the source image for separate part of the final high dynamic range (HDR) image, either by creating a image mask or scribble on the image. The high dynamic range (HDR) image synthesis includes the following steps: capturing low dynamic range images with different exposures; registering the low dynamic range images; estimating camera response function; converting the low dynamic range images to temporary radiance images using estimated camera response function; and fusing the temporary radiance images into a single high dynamic range (HDR) image by employing a method of layered masking.

摘要： A method and system for calibration and compensation of color in a three dimensional display system includes user calibration of individual color channels using a multiplicity of grey screens while viewing with three dimensional glasses. Look-up tables are generated to ease conversion of input pixels to color corrected pixels to pre-distort the color of the pixels being driven by the three dimensional display system. Input pixels are then converted using the look-up tables and color corrected frames are displayed to a user. The pre-distortion effect allows a user to perceive colors in the three dimensional system as intended with the distortions caused by the viewing glasses and other aspects of the three dimensional display system.

摘要： At least one implementation reduces chromatic aberration by aligning pixel in a color channel according to displacement from corresponding pixels in another color channel. In one particular implementation, a feature is calculated for a first block of pixels in a first color channel of an image. The feature is calculated for a second block of pixels in a second color channel of the image. Displacement is estimated between the first color channel and the second color channel by comparing the feature for the first block and the feature for the second block. At least a portion of the first color channel is aligned with at least a portion of the second color channel based on the estimated displacement.
