Abstract: A method for photographing a panoramic picture includes the steps of checking motion of a corresponding photographing apparatus compares currently input images and previous images in real time through a motion estimation technique employing exposure compensation. Respective images constituting a panoramic picture are photographed, and image photography information is checked that includes focus distance and optical magnification to calculate actual photography range distance of the images. A pre-set threshold is set in consideration of a calculated actual photography range distance of the images. The checked motion is confirmed as to whether the pre-set threshold has been reached, and photography time points of the respective images are determined. The respective images are photographed according to a manual mode or an automatic mode at the photography time point of the respective images.

Abstract: Disclosed is a method and an apparatus for recognizing characters using an image. A camera is activated according to a character recognition request and a preview mode is set for displaying an image photographed through the camera in real time. An auto focus of the camera is controlled and an image having a predetermined level of clarity is obtained for character recognition from the images obtained in the preview mode. The image for character recognition is character-recognition-processed so as to extract recognition result data. A final recognition character row is drawn that excludes non-character data from the recognition result data. A first word is combined including at least one character of the final recognition character row and a predetermined maximum number of characters. A dictionary database that stores dictionary information on various languages using the first word is searched, so as to provide the user with the corresponding word.
