Abstract: A method, apparatus and computer program product are provided to combine images captured by multiple cameras into a composite panoramic image, such as a 360° panorama, in a manner that reduces image defects and other artifacts at or near a seam between images. In some implementations of example embodiments, the overlapping portions of two images are divided into a plurality of seam regions. Upon selection of a seam region, the seam region is further divided into seam segments. In each seam segment, a depth level associated with the segment is used to calculate convergence value that is applied such that different scaling factors may be applied to image elements at different depths within a given image. Based on the applied convergence values and the resulting stitching at the seam region the image quality at the seam area can be efficiently improved.
