Claim Text:
1. A method for photographing in an electronic device a panoramic image composed of a plurality of pictures, the electronic device performing the operations of: comparing, by an image processor circuitry, a current real-time input image obtained by an image sensor circuitry with a previously-obtained image, and through operation of a motion estimation mechanism, determining a motion vector between images to recognize movement of a corresponding photographing apparatus of the electronic device; determining, by the image processor circuitry, a time to photograph each next picture of the plurality of pictures by determining whether the recognized movement in a photography direction reaches a preset threshold value; and photographing, by the photographing apparatus, each next picture by manual or automatic operation at the determined time, and generating the panoramic image, wherein in the motion estimation mechanism includes: determining the motion vector between matching image blocks using error information of respective compared pixels between image blocks within compared frames.
