Abstract:
1. A method for photographing a panoramic picture, comprising the steps of: (a) obtaining a first image by a photographing apparatus in response to a request for a panoramic picture photography; (b) identifying a motion of the photographing apparatus having obtained the first image, by applying a first motion estimation technique to currently input images that simultaneously identifies vertical and horizontal motions that are continuously accumulated up to a preset threshold value; (c) automatically determining a photographing direction based on the identified motion of the photographing apparatus; (d) selectively applying a second motion estimation technique for estimating motion for at least one of a horizontal direction utilizing a motion vector corresponding to the X-axis or a vertical direction utilizing a motion vector corresponding to the Y-axis, according to the determined photographing direction, and identifying motion of the photographing apparatus thereby; (e) judging photographing time points of respective images by identifying that the identified motion of the photographing apparatus from step (d) has reached the preset threshold value for decision of a photographing time point, which preset threshold value comprises motion vector values accumulated in the vertical or horizontal directions; and (f) photographing images at the photographing time points of the respective images.
