Abstract

A method of rendering an output image (202) on basis of an input image (200) and a corresponding matrix of depth related data (204), the input image (200) corresponding to a first viewpoint and the output image (202) corresponding to a second viewpoint being different from the first viewpoint comprises computing edges (212,312) in the matrix of depth related data (204), computing a measure of variation in pixel values in regions of the input image (200) corresponding to neighborhoods of the edges (212,312), and computing the output image (202) by shifting respective pixel values of the input image (200) in the predetermined direction (X) on basis of scaled depth related data. Scaling, via the scaled depth related data, is such that a relative large measure of variation results in a relative large reduction of depth for the scaled depth related data.
