In addition, the extraction unit 13 may hold information indicating a normal arrival time (a moving time) between a plurality of attractions in advance. By using the information, provision image data to be excluded from an object to be extracted may be determined. For example, in a case where the first information determines that the person was present at the attraction A at 11:00 and the normal arrival time from the attraction A to an attraction B is 5 minutes, provision image data captured and generated at the attraction B from at 10:55 and to at 11:05 is excluded from an object to be extracted.

Further, based on an imaging location and an imaging date and time of provision image data including a person having a similarity with a person included in reference image data equal to or larger than a reference value, the extraction unit 13 may exclude provision image data generated at a location and an imaging date and time at which the person at the imaging location at the imaging date and time cannot reach within the normal arrival time, from an object to be extracted.

According to the present example embodiment, the same advantageous effect as the first example embodiment can be realized. In addition, according to the present example embodiment, it is possible to improve accuracy of extracting provision image data including a person included in reference image data.

It should be noted that, the electronic tag may be passed to the visitor on the location. Further, the electronic tag may be embedded in an annual pass or the like. In addition, the portable terminal may be a smartphone, a tablet, or the like installed with a predetermined application.
