Image classifying device, image classifying system, image classifying method, and recording medium

An image classifying method comprising the steps of:

• acquiring a plurality of pathway data including a first person information for identifying a person, pathway information that is location information indicating a continuous pathway followed by the first person both when an image is acquired and when an image is not acquired, date information indicating a day on which the location information was acquired, and time information at which the location information was acquired;
• acquiring image data containing a second person information on a predetermined person and imaging date/time information;
• comparing the acquired plurality of pathway data;
• determining an occurrence of an event and determining the date/time of the event based on a difference in the location information corresponding to the same time information in the compared plurality of pathway data and outputting an event occurrence signal which contains pathway data corresponding to the date/time of event and an event date/time information;
• and
• checking the first person information retrieved from the pathway data contained in the event occurrence signal against the second person information contained in the acquired image data and classifying image data containing the second person information which agrees with the first person information and the imaging date/time information corresponding to the event date/time information contained in the event occurrence signal as event image corresponding to the determined date/time of the event,
• the pathway information is the continuous location information indicating the pathway followed by the first person including an imaging place where the image data is acquired and other locations,
• the plurality of continuous location information indicating the pathway followed by the first person including the imaging place where the image data is acquired and other locations are compared, and
• the occurrence of event and the date/time of event are determined based on a difference in the location information indicating the pathway followed by the first person, as compared to the pathway followed by the second person, including the imaging place where the image data is acquired and other locations corresponding to a time when the time information of the plurality of pathway data agree, the event being determined by the pathway of the first person being different from the pathway of the second person during a same period of time.

A computer readable non-transitory medium configured to store an image classifying program for causing a computer to execute, the program comprising the steps of:

• acquiring a plurality of pathway data including a first person information for identifying a first person both when an image is acquired and when an image is not acquired, pathway information that is location information indicating a continuous pathway followed by the person, date information indicating a day on which the location information was acquired, and time information at which the location information was acquired;
• acquiring image data containing a second person information on predetermined person and imaging date/time information;
• comparing the acquired plurality of pathway data;
• determining an occurrence of an event and determining the date/time of the event based on a difference in the location information corresponding to the same time information in the compared plurality of pathway data and outputting an event occurrence signal which contains pathway data corresponding to the date/time of event and an event date/time information;
• and
• checking the first person information retrieved from the pathway data contained in the event occurrence signal against the second person information contained in the acquired image data and classifying image data containing the second person information which agrees with the first person information and the imaging date/time information corresponding to the event date/time information contained in the event occurrence signal as event image corresponding to the determined date/time of the event,
• the pathway information is the continuous location information indicating the pathway followed by the first person including an imaging place where the image data is acquired and other locations,
• the plurality of continuous location information indicating the pathway followed by the first person including the imaging place where the image data is acquired and other locations are compared, and
• the occurrence of event and the date/time of event are determined based on a difference in the location information indicating the pathway followed by the first person, as compared to the pathway followed by the second person, including the imaging place where the image data is acquired and other locations corresponding to a time when the time information of the plurality of pathway data agree, the event being determined by the pathway of the first person being different from the pathway of the second person during a same period of time.
