Patent ID: 7405752

Claim:
A mobile communication terminal comprising: position information acquiring means for acquiring position information; photographing means for acquiring images of field; position information assigning means for associating each of the images, which are acquired by the photographing means in a predetermined time interval, with the position information which is acquired by the position information acquiring means and specifies the position at which the image is acquired; video generating means for generating a video including frames each associated with the position information concerning the acquired position, based on a plurality of images which are photographed by the photographing means and include the images each associated with the position information by the position information assigning means; storage means for storing the video generated by the video generating means and items of the position information which are associated with the frames included in the video; transmitting means for transmitting the video and the items of position information associated with the frames included in the video, which are stored in the storage means; and frame rate adjusting means for adjusting the frame rate of the video, based on a plurality of images acquired by the photographing means including the images each associated with the position information by the position information assigning means, the frame rate adjusting means dividing the plurality of images into a plurality of groups including a predetermined number of images based on the order in which the images are acquired, determining, for each of the groups, direction information indicating the direction of a travel locus based on the position information associated with the predetermined number of images in the corresponding group, setting, for each of the groups, a frame rate for the video based on the predetermined number of images in the corresponding group to a first frame rate when a direction change amount based on the direction information determined for the corresponding group and the direction information determined for at least one of the previous group and the next group is larger than a predetermined amount and settings the frame rate to a second frame rate lower than the first frame rate when the direction change amount is equal to or smaller than the predetermined amount, wherein the video generating means generates the video using the plurality of images, according to the frame rate determined for each of the plurality of groups.
