IMAGE PROCESSING METHOD AND APPARATUS AND STORAGE MEDIUM

An image processing apparatus includes a frame specifying processor which specifies, from within a dynamic image, a frame having a background which is to be used, a background region specifying section which specifies a background region from an image of the specified frame, a background generator which generates an entire background from the specified background region and outputs a background data, and a non-background region setting section which creates a non-background region data in which a non-background region flag is set within a region where no background exists in the entire background which is generated. The background data and the non-background region data form a background object image.
