Abstract:
1. A method for processing movement data in synchronous video, the method comprising: obtaining a first frame of digital data corresponding to a digital image; generating a color-table for the first frame of the digital data, the color-table corresponding to at least one pixel color contained within the first frame; mapping the first frame of digital data according to the color-table; obtaining a preceding frame of digital data corresponding to the digital image; representing a cumulative color difference between the first and the preceding frames of the digital data in a pseudocolor, wherein the pseudocolor is configured to map cumulative color differences below a movement threshold in a grayscale and cumulative color differences above the movement threshold in at least one distinct color; and updating a frame data with the pseudocolor if the cumulative difference is above a difference threshold, wherein the frame data is operable to regenerate the first frame of the digital data.
