<P>PROBLEM TO BE SOLVED: To provide a photographing program capable of computing the direction of the movement of an object to be photographed by a simple structure. Ž<P>SOLUTION: An angle θb between an imaging plane of a digital camera 1 and the direction of the movement of the object to be photographed is computed by using a first reference size R1 and a second reference size R2 for the object to be photographed which is registered beforehand, a reference angle θa stored beforehand, and a size R3 of an object image specified by photographic image data. Thereby, the direction of the movement of the object to be photographed can be computed without using a gyroscope sensor etc. As the result, the direction of the movement of the object to be photographed can be computed by a simple structure.
