Claim:
1. A method for determining field of view dependent depth map correction values for correction of a depth map of an image taken with a lens having a field of view, comprising: obtaining a first focus measure and a second focus measure of a test image for at least a first and a second depth; determining edge orientations for image features at at least two different predetermined locations of the test image for the at least first and second depth; obtaining relative depth information for at least two different depths and at least two different predetermined locations of the field of view of the lens on the basis of the first and the second focus measure of the test image and on the basis of the determined edge orientations at the at least two different predetermined locations of the test image; receiving an image; determining a depth of the received image; and determining on the basis of the determined depth of the received image at least one depth map correction value on the basis of the relative depth information.
