Method and apparatus for determining a depth map for an angle

An apparatus for generating a depth map, the apparatus comprising:

• an image generator circuit arranged to provide an image and an associated depth map, wherein the associated depth map comprises input depth values;
• a contour detector circuit arranged to detect at least a first contour in the image, the first contour comprising a first set of pixels;
• a model processor circuit arranged to generate a contour depth model for the first contour by fitting a depth model to input depth values for the first set of pixels;
• a depth value determiner circuit arranged to determine a depth model depth value for at least a first pixel of the first set of pixels from the contour depth model;
• and
• a modifier circuit arranged to generate a modified depth map from the associated depth map by modifying depth values of the associated depth map;
• wherein the modifier circuit is further arranged to generate a first modified depth value for the first pixel in the modified depth map in response to the depth model depth value.
