Patent ID: 8817013

Claim:
A computer implemented method for editing a stereoscopic image composed from image data of a plurality of frames each frame including pixel image data depicting an image, the pixel data corresponding to data stored in an at least two dimensional matrix, indices of which correspond to coordinates in the image or a partial image and to one or several value groups for the indices, the pixel image data comprising a plurality of segments, editing of the pixel image data being carried out in a plurality of editing modules according to an execution sequence and depending on a plurality of adjustable editing parameters, each one of the plurality of editing modules executing at least one editing step, the execution sequence being determined by a selectable linking of the plurality of editing modules, wherein each one of the plurality of editing modules can exchange data with the editing modules it is linked to in accordance with the execution sequence, and wherein for each two of the editing modules linked in the execution sequence the method comprises: communicating from a preceding one of the two editing modules to a succeeding one of the two editing modules, which segments of the pixel image data available to the preceding editing module are affected by a change to one of the plurality of editing parameters; communicating from the succeeding editing module to the preceding editing module, which portions of the affected segments of the pixel image data are necessary for execution of the at least one editing step in the succeeding editing module; and transmitting from the preceding editing module to the succeeding editing module, re-computed pixel image data for only the portions of the affected segments of the pixel image data necessary for execution of the at least one editing step in the succeeding editing module; wherein only a subset of pixel image data of a given frame which the succeeding editing module identifies as necessary is recomputed and transmitted by the preceding editing module to the succeeding editing module.
