In a photo movie producing apparatus, a scenario producing section includes a parameter normalizing circuit which normalizes a parameter in a scenario into a format based on a predetermined pixel number not dependent on a pixel number of still images to be inputted in an image editor and an edited image. The image editor handles the still images and the edited image within a virtual pixel space by using the normalized parameter. In a preferred embodiment, each still image is normalized to a pixel number in accordance with an output format of a photo movie, before the image editing.
