An electronic camera includes an imager. An imager, having an imaging surface capturing a scene, repeatedly outputs a scene image. An extractor checks the scene image outputted from the imager with each of a plurality of characteristic patterns so as to extract one or at least two characteristic patterns in each of which a checking degree exceeds a reference. A creator creates a reference image based on the scene image outputted from the imager corresponding to the first extraction by the extractor. A selector selects a characteristic pattern used for searching for an image coincident with the reference image created by the creator, from among one or at least two characteristic patterns extracted by the extractor.
