PROBLEM TO BE SOLVED: To improve determination accuracy.SOLUTION: An information processing apparatus 10 stores position information indicating a positional relation between a specific position and a first feature point of a reference image Pand a count value corresponding to sub-areas of an input image P, specifies a sub-area located in the specific position when the first feature point is aligned with a second feature point similar to the first feature point, out of the second feature points of the input image P, executes processing of increasing a count value corresponding to the sub-area, for each of the first feature points, determines that the reference image Pis included in the input image Pwhen a maximum value Max of the count value is larger than a threshold Th, and determines that the reference image Pis included in the input image Pwhen the maximum value Max is less than the threshold Th and the sum Sum of the count values in a range set based on the maximum value Max along one direction, where a distribution of the count values are extended in the one direction, is larger than the threshold Th.SELECTED DRAWING: Figure 1 |
