摘要： System and method for generating multiprimary signals with optimization for bit depth for use in display devices. A preferred embodiment comprises converting an input color signal into an output color signal, wherein the number of colors in the output color signal is less than a number of colors used in a display system, when a weighting of the input color signal is less than a specified threshold, and converting the input color signal into an output color signal, wherein the number of colors in the output color signal is equal to the number of colors used in the display system, when the weighting of the input color signal is greater than the specified threshold. The use of fewer colors eliminates low bit depth colors, allowing increased dither quality in dimmer images.

摘要： System and method for processing image data containing motion for display on a display device. A preferred embodiment comprises applying a filter to an input image, determining a presence of motion in the input image, and generating an output image from the input image and the filtered image based upon motion in the input image. The detection of motion in the input image permits the use of filtered image data in portions of the image containing motion, thereby taking advantage of aliasing reduction provided by the filter while allowing the use of unfiltered image data in portions not containing motion. This helps to preserve image quality since filtering softens the image.

摘要： A digital keystone correction process locates image points in a corrected image from image points in a distorted image that was produced by misalignment of the axis of a sensor such as a camera. The correction process locates corrected image points by constructing intercept points that are the intersections of the extended sides of a quadrilateral in the distorted image plane that is constructed from a known rectangular feature in the subject plane. Reference points are located by drawing a line through each intercept point and the distorted image point. Distances are found from the intercept points to the image points and the reference points. The distances are scaled and corrected with an offset to locate the coordinates of the image points in the corrected image plane. This process can correct alignment errors of pitch, yaw, and roll between the subject plane and an image plane such as photographic film.
