Abstract: An image synthesizing apparatus which is capable of, when synthesizing moving images, carrying out an image synthesizing process without bringing about increases in processing time and the amount of transfer to memory irrespective of the number of images to be synthesized. A preset number of frames are synthesized to obtain a first synthesized image. When an image of another frame is to be synthesized with the first synthesized image, an image of a predetermined frame used for the synthesis obtaining the first synthesized image is subtracted from the first synthesized image, and the image of the other frame is added to the first synthesized image to generate a synthesized image.
