PROBLEM TO BE SOLVED: To prevent the situation in which feature amounts of images similar to each other are stored in a single database.SOLUTION: A control unit extracts a feature amount indicating a feature of a processing target image in a feature extraction target area set by a user, and stores the extracted feature amount in a database associating with a URL input by the user (S303A). At this time, when a feature amount is already stored in the database, which has similarity to the extracted feature amount to a certain extent or more, the control unit does not store the extracted feature amount in the database and outputs predetermined notification information to the user. |
