PROBLEM TO BE SOLVED: To easily extract a candidate of relatively-important image data within a plurality of still image data or moving image data imaged by a plurality of digital camera or video camera when the plurality of still image data or moving image data exist. SOLUTION: The attribution information of a plurality of image data imaged by a plurality of imaging devices is obtained. The image data are classified into predetermined time zones on the basis of an imaging date and time obtained from the attribution information. The number of the imaging devices which have imaged the image data classified on a predetermined time zone basis is determined, and the image data classified into the time zone of which the number is larger than a threshold value are extracted. The extracted image data are discriminated from the other image data to be displayed. Thereby, even when a plurality of still image data or moving image data imaged by a plurality of digital cameras or video cameras exist, a candidate of the image data relatively-important within them can be extracted easily.
