INFORMATION PROCESSOR, INFORMATION PROCESSING METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an information processor which can accurately detect an image corresponding to an object image.SOLUTION: An information processor searching a plurality of first images for an image corresponding to a second image includes: a detection part which detects from one or more first points of interest detected from a first image a first point of interest similar to a second point of interest every one or more second points of interest detected from the second image; a calculation part which calculates the number of the second points of interest similar to the first point of interest as the number of votes for each the one or more first points of interest detected by the detection part; a correction part which changes the number of votes to a predetermined value when the number of votes calculated by the calculation part is a prescribed number or larger; and a search part which searches for a first image whose number of votes every first image satisfies a prescribed condition based on at least either the number of votes calculated by the calculation part or the number of votes changed by the correction part as a first image corresponding to the second image from a plurality of first images.SELECTED DRAWING: Figure 1
