In the image taking method where images of an object are taken by a running image taking portion provided with a zoom lens, and at least one image taking portion for measuring a distance provided with a fixed focus lens equal to the wide-angle-side end of the zoom lens to generate image data, an image taking method includes the steps of simultaneously taking an image by each image taking system and detecting and storing a zoom position at an arbitrary angle of view of the zoom lens. A search space in a photographing field in the stored zoom position is set. When it is determined that no corresponding point is on one of the end faces of the set space, a running image is taken after the zoom lens is moved to the stored zoom position by the zoom lens drive means.
