An image position adjusting apparatus adjusts the position plurality of images such that the plurality of the images may overlap one upon another. An image display device reproduces the respective images from image signals, which represent the respective images, and displays the reproduced images. A transformation device transforms each of the images, which are displayed on the image display device, into a simple image. The simple image is represented by only the image signal components of the image signal representing each of the displayed images, which image signal components have signal values larger than a predetermined threshold value. A polygon display device displays an arbitrary polygon on each of the simple images. A shift device shifts the polygon displayed on each of the simple images. A deformation device deforms the polygon, which is displayed on one of the simple images, and deforms the polygons, which are displayed on the other simple images, so as to interlock with the deformation of the polygon, which is displayed on one of the simple images. A rotation device rotates the polygons, which are displayed on the other simple images.
