Abstract: The present invention is to provide a method for enabling an electronic device to read at least two images taken from different positions by a digital camera mounted with a fisheye lens; acquire internal and external parameters of the fisheye lens corresponding to the different positions as well as the vignetting coefficient for eliminating the vignetting on the images; perform exposure compensation and color calibration on the images for letting them have consistent brightness and hues; project the images onto a spherical surface and spread out the spherical surface to form a two-dimensional spread-out picture based on the parameters; register the overlapped images projected on the two-dimensional spread-out picture and adjust the offset of corresponding pixels thereof, register and adjust the brightness and hues of the overlapped images into consistency; and fuse overlapped images together to produce a 360-degree spherical panorama without having any noticeable stitching seam between the images.

Abstract: The present invention is to provide a method for achieving a clear and precise optical zooming mechanism, which is applied to an electronic device equipped with a wide-angle image capturing element and a long-focus image capturing element. The wide-angle image capturing element and the long-focus image capturing element are controlled by the electronic device for capturing a wide-angle image and a long-focus image of a same spot simultaneously and respectively. The method enables the electronic device to sequentially perform an exposure and white balance adjustment process, a robust image matching algorithm and an image morphing fusion process to the wide-angle image and the long-focus image, respectively, so as to generate a clear and precise optical zooming image of the spot without having a significant skipping phenomenon occurred in an object within two zooming images.

Abstract: The present invention is to provide a method for ensuring perfect stitching of a subject's images in a real-site image stitching operation, which enables an electronic device to read two real-site images which are taken respectively of different parts of the same site and each of which has an overlap area of a common subject; to determine and choose an optimal stitching path bypassing the subject; to construct a mask diagram such that, within a difference diagram of the overlap areas, the farther a pixel on one side of the optimal stitching path is from the optimal stitching path, the greater the pixel's value, and the farther a pixel on the other side of the optimal stitching path is from the optimal stitching path, the smaller the pixel's value; and to stitch and fuse the overlap areas together through a fusion algorithm, with the mask diagram serving as a weight.
