Abstract: A digital image processing, in particular to the method of producing the output image with extended depth of field from a group of source images of the same scene, captured with a shift of depth of field. The method of producing the output image with extended depth of field form a group of at least two source images of substantially the same scene captured with a shift of depth of field, comprises determining focus measures of source image pixels; generation of a depth map with elements comprising source image indices; smoothing of the depth map in a way that the degree of smoothing of source image indices it contains is inversely proportional to the corresponding focus measure values; producing an output image using the smoothed depth map. A computer system that implements said method, and a computer readable medium comprising program instructions allowing for implementing said method.
