METHOD, APPARATUS AND SYSTEM FOR PROCESSING DEPTH-RELATED INFORMATION
First Claim
1. Method of processing first depth-related information (110) associated with an image sequence (105), comprising mapping (140) first depth-related information (110) of respective images of a shot of the image sequence on corresponding second depth-related information (150) using a first estimate (135) of a characteristic of the distribution of first depth-related information associated with at least one image from the shot, the mapping (140) adapting the first depth-related information by enhancing the dynamic range of a range of interest of first depth-related information defined at least in part by the first estimate, and wherein the amount of variation in the mapping (140) for respective images in temporal proximity in the shot is limited.

Abstract
The invention relates to a method, apparatus and system for processing first depth-related information associated with an image sequence. The method of processing comprises mapping first depth-related information of respective images of a shot of the image sequence on corresponding second depth-related information using a first estimate of a characteristic of the distribution of first depth-related information associated with at least one image from the shot, the mapping adapting the first depth-related information by enhancing the dynamic range of a range of interest of first depth-related information defined at least in part by the first estimate, and the amount of variation in the mapping for respective images in temporal proximity in the shot being limited.
