ABSTRACT:
An image processing system for performing a transformation of an input image associated with an input viewpoint to an output image associated with an output viewpoint. The input image is a pre-filtered 2D representation of 3D objects as seen from the input viewpoint, and comprises for each input pixel an associated input pixel value and an associated input pixel depth. Additional to the input image a hidden image is received, being another 2D representation of the 3D objects and comprising information, which information is occluded from the input viewpoint.The system comprises a video processor being operative to create the output image by transforming each input pixel to a transformed input pixel. The transformation is a function of the input pixel depth. The output image is created, based on the transformed input pixels, using hidden image pixels for filling de-occluded areas and for at least one pixel position adjacent to the de-occluded areas. As a consequence ghost line artifacts, caused by transformation of the pre-filtered input image, are prevented.
