1. An output apparatus, comprising: a moving image acquiring section that acquires a moving image; a moving object extracting section that extracts a moving object in the moving image acquired by the moving image acquiring section; an object area identifying section that identifies an object area, which is an area occupied by the object extracted by the moving object extracting section in each moving image component image in a plurality of moving image component images included in the moving image acquired by the moving image acquiring section; a moving image component image selecting section that selects a plurality of moving image component images in which the object areas identified by the object area identifying section are not in positions that overlap with one another from among the plurality of moving image component images included in the moving image acquired by the moving image acquiring section; an image generating section that generates a single synthesized image by superimposing images that include a plurality of object areas included in each moving image component image in the plurality of moving image component images selected by the moving image component image selecting section; and an output section that outputs the synthesized image generated by the image generating section.
