PROBLEM TO BE SOLVED: To implement a method in which the specified part of a subject on a plurality of pictures taken at positions whose distance from a photographic lens is different is detected and the image forming position of the subject is detected based on the detected position and the distance from the photographic lens to each picture taking position fit for practical use. SOLUTION: The position of the subject on a plurality of pictures is detected after correcting all of the difference of the position of the subject on the respective pictures made because a plurality of pictures are taken at different time, the difference of the lightness of the respective pictures made because the distance from the photographic lens is different and the difference of the size of the subject on the respective pictures. Then, a digital camera is equipped with a program on which processing for detecting the image forming position is recorded, and the automatic focusing of the digital camera is quickened. |
