Claim:
1. A method for photographing a panoramic image, operable by an image processor of a digital photographing apparatus, the method comprising the steps of: comparing, by the image processor, a current image input with a previous image stored in a non-transitory memory to obtain motion information of the digital photographing apparatus when photographing respective images forming the panoramic image; recognizing, by the image processor, a degree of movement and a direction of motion of the digital photographing apparatus at least based on the obtained motion information in which horizontal motion vector information and vertical motion vector motion information of at least one or more pixel blocks are obtained respectively; indicating, via a user interface, a suggested direction toward which a user moves the digital photographing apparatus based on the obtained motion information; photographing, by a camera hardware module of the digital photographing apparatus, a corresponding image by a manual input, or automatically when the recognized degree of movement of the digital photographing apparatus satisfies a pre-set movement distance reference; and generating the panoramic image of the photographed respective images when a quantity of the respective photographed images reaches a predetermined count, wherein the comparing the current image input with the previous image is in real time, and wherein, comparing the current image input in real time with the previous image includes setting a central portion of the current image input as a motion region tracking section, and comparing only the motion region tracking section with a corresponding central portion of the previous image to obtain the motion information.
