    • 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.
    • 本发明的目的是提供一种改善缝合过程的方法。 该目的通过用于创建组合图像的电子设备中的方法来实现。 该方法包括获得(701)由阵列照相机记录的至少两个子图像的第一组。 该方法还包括获得(702)由阵列照相机记录的至少两个子图像的第二组。 对于第一组子图像计算第一深度图。 第一深度图包括关于子图像的第一平面和子图像的第二平面的信息。 第一平面处于与已经记录了子图像的点之间的第一距离处,并且第二平面处于距离已经记录了子图像的点的第二距离处。 针对第二组子图像计算第二深度图。 第二深度图包括关于第一平面和第二平面的信息。 该方法还包括在第一平面中缝合第一组子图像和第二组子图像,从而获得第一缝合图像。 第一组子图像和第二组子图像被缝合在第二平面中,从而获得第二缝合图像。 最后,该方法包括组合第一缝合图像和第二缝合图像,从而创建组合图像。
