Abstract

Method for enhancing the depth sensation of an image (22),which method comprises the steps of: obtaining the depth of pixels depicting objects (24, 26) located in at least one part of the image (22), calculating a weight for pixels depicting objects (24, 26) located in said at least one part of the image (22) as a function of their depth, generating a depth-dependent histogram (17), using the weighted pixel data, calculating a correction curve (19) from the depth-dependent histogram (17), and applying the correction curve (19) to the entire image (22).
