Abstract

A device for splicing together sub-images for a single panorama image searches a plurality of images taken from different angles in an image library. Modules in the device receive basic information and obtain image searching information. First images are extracted from the image library according to the image searching information and second images that comprise different azimuth angles and match a predetermined environmental parameter are selected from the first images. An optimal image of each azimuth angle is extracted from the second images according to environmental and image parameters and adjustments to each optimal image are made to splice together the panorama image. A panorama image generating method is also provided.
