AN IMAGE PROCESSING APPARATUS AND METHOD

摘要

The invention relates to an image processing apparatus (100) for selecting a depth information value (dbest) for a current fragment of a current digital image. The image processing apparatus (100) comprises a memory (101) configured to store a previously selected depth information value (dprev) selected for a previously processed fragment and a signal processing logic (103). The signal processing logic (103) is configured to calculate a similarity measure for the current fragment based on a depth information value candidate defining a reference fragment candidate of a digital reference image, compare the depth information value candidate with the previously selected depth information value (dprev), apply a weighting function on the calculated similarity measure to obtain a weighted similarity measure for the current fragment based on the comparison between the depth information value candidate and the previously selected depth information value (dprev), and determine whether to select the depth information value candidate as the depth information value (dbest) for the current fragment depending on the weighted similarity measure of the depth information value candidate.
