Modifying a perceptual attribute of an image using an inaccurate depth map

-33 Abstract A method of modifying a perceptual attribute of an image using a corresponding depth map of a scene captured by the image. A visibility measure is determined for image artefacts 5 produced in each of a plurality of regions of the image by each of a set of image adjustment processes when applied to content of the image in accordance with depth values in the depth map. The image artefacts are caused by inaccurate depth values of the corresponding depth map. A first and second image adjustment process is selected from the set of image adjustment processes based on respective determined visibility measures. A perceptual attribute of the image is 0 modified by locally applying the first and second selected image adjustment processes to different respective regions of the image. 17(19977Rv1 (P2S1416 As Filed)
