摘要:
An object of the present invention is to provide a way of improving the stitching procedure.The object is achieved by a method in an electronic device for creating a combined image. The method comprises obtaining (701) a first set of at least two sub-images recorded by an array camera. The method further comprises obtaining (702) a second set of at least two sub-images recorded by the array camera. A first depth map is calculated for the first set of sub-images. The first depth map comprises information about a first plane of the sub-images and a second plane of the sub-images. The first plane being at a first distance from the point where the sub-images have been recorded, and the second plane being at a second distance from the point where the sub-images have been recorded. A second depth map is calculated for the second set of sub-images. The second depth map comprises information about the first plane and the second plane. The method further comprises stitching the first set of sub-images and the second set of sub-images in the first plane, and thereby obtaining a first stitched image. The first set of sub-images and the second set of sub-images are stitched in the second plane, and thereby obtaining a second stitched image. Finally the method comprises combining the first stitched image with the second stitched image and thereby creating the combined image.
