摘要： The present principles provide for a color processing system. The color processing system includes an image processor configured to color correct a first image sequence based on a second image sequence. The image processor determines a first spatio-temporal picture for a first block of the first image sequence and a second spatio-temporal picture for a second block of the second image sequence. The first block of the first image sequence corresponds in location, disparity and geometry to the second block of the second image sequence. The image processor determines a transform based on color look grabbing of the first spatiotemporal picture and the second spatio-temporal picture. The image processor color corrects the first image sequence by applying the transform to the first block of the first image sequence.

摘要： A method and apparatus for providing a three-dimensional display to a viewer is disclosed. If a color difference between pixels of a right eye image area and corresponding pixels of a left eye image area is greater than or equal to a predefined difference threshold, a parallax barrier is controlled to block either the right or the left eye image area from the viewer. Otherwise, if the color difference is less than the predefined threshold, the parallax barrier is controlled to display both the right and left eye image areas to the viewer. Corresponding devices to implement the method are also disclosed. The method may be performed by an autostereoscopic display controller, or a pair of active shutter glasses, for example.

摘要： A processor-controlled machine computes a color calibration or performs an evaluation of the color of images of multi-view or stereoscopic images. A fictive transformation matrix is used for substituting variables of a first set of polynomials calculated from a 3D color histogram describing the 3D color histogram distribution of the pixels in a 3D color space of a reference image of the multi-view or stereoscopic image. A second set of polynomials is set equal to a number of histogram elements of the image at least to be calibrated for providing a transformation matrix for color calibration and also applicable for evaluating the quality of the color of images of multi-view or stereoscopic images.

摘要： A mode setting part 112 has a function to selectively set 2D and 3D display output modes. A play control part 132 changes the manner in which to control switching between display images in accordance with the display output mode set by the mode setting part 112. The play control part 132 changes the opacities of first and second display images with time so that when the two display images are cross-faded, the sum of the opacities of the first and second display images in a 3D display output mode is equal to or smaller than the sum of the opacities of the first and second display images in a 2D display output mode during a cross-fading period.
