Abstract:
1. A method of rendering an output image on basis of an input image and a corresponding matrix of depth related data, the input image corresponding to a first viewpoint and the output image corresponding to a second viewpoint being different from the first viewpoint, the method comprising: computing edges, via an edge detection unit, in the matrix of depth related data, by computing only derivatives of the depth related data in a predetermined direction (X), the edges corresponding to edges between (i) an object in a foreground of the input image and (ii) a background of the input image; computing a measure of variation in pixel values of the input image, via a texture analyzing unit, in regions of the input image that form a pixel subset (S computing the output image, via scaling and rendering units, by shifting respective pixel values of the input image in the predetermined direction (X) on basis of scaled depth related data, wherein the scaled depth related data comprises depth related data having been scaled on basis of the computed measure of variation, further wherein scaling via the scaled depth related data is such that a relative large measure of variation in pixel values in the regions of the input image that form the pixel subset (S
