IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND IMAGE PROCESSING PROGRAM

An image processing apparatus includes a processor to: sequentially acquire plural subject images; select a detection target image from the plural subject images; detect the location of interest in the detection target image; generate spatial information of a superimposed object indicating the location of interest on one of the plural subject images; select a superimposition target image to be superimposed, from the plural subject images; generate inter-image correspondence information between the detection target image and the superimposition target image; correct the spatial information of the superimposed object, based on the inter-image correspondence information; and superimpose the superimposed object on the superimposition target image. The processor is configured to repeatedly execute the selecting the superimposition target image, the generating the inter-image correspondence information, the correcting the spatial information, and the superimposing the superimposed object, until the spatial information of the superimposed object is generated for the detection target image.
