A data processing apparatus (1) of the present invention includes a unit that retrieves a predetermined subject from moving image data. The data processing apparatus includes a person extraction unit (10) that analyzes moving image data to be analyzed and extracts a person whose appearance frequency in the moving image data to be analyzed satisfies a predetermined condition among persons detected in the moving image data to be analyzed, and an output unit (20) that outputs information regarding the extracted person.

說(shuō)明書(shū)

By outputting the appearance frequency in the moving image data to be analyzed in association with each of the plurality of persons extracted by the person extraction unit 10, it is possible to easily recognize the appearance frequency of each person. Based on such information, it is possible to narrow down the persons to be retrieved.

By outputting information indicating the temporal change in appearance frequency in association with each of the plurality of persons extracted by the person extraction unit 10 as shown in FIG. 10, it is possible to recognize the appearance pattern of each person. Based on such information, it is possible to narrow down the persons to be retrieved. By appropriately setting the time width of the time window or the scale interval on the horizontal axis in the shown graph, it is possible to obtain desired information.

By showing the face image of the person and the presence or absence of appearance in each of the plurality of time windows in association with each of the plurality of persons extracted by the person extraction unit 10 as shown in FIG. 11, it is possible to easily recognize the presence or absence of appearance in each time window.
