Information Processing Apparatus and Information Processing Method

An information processing apparatus comprising:

• a database configured to store a plurality of data including a three-dimensional image containing a plurality of images obtained when an object in a three-dimensional space is viewed from different viewpoints and a two-dimensional image corresponding to the three-dimensional image, and configured to store respective file names that are capable of uniquely identifying the plurality of image data and respective shooting timestamps, including the year, month, day, and time of shooting of the respective plurality of image data;
• an image classifying unit configured to identify the two-dimensional image corresponding to the three-dimensional image, based on the respective file name and timestamp;
• and
• a list displaying unit configured to display on a display device a list of thumbnail images that exclude the two-dimensional image identified by the image classifying unit.

An information processing method executable by a processor, the method comprising:

• displaying on a display device a list of thumbnail images of a plurality of image data in a database that stores a plurality of image data to which a shooting timestamp, including the year, month, and day of the shooting, is attached as attribute information;
• acquiring a thumbnail image, which is among the displayed thumbnail images, as a specified image;
• generating one or a plurality of groups of images by classifying the plurality of respective image data in terms of the respective year of the shooting timestamp, when the specified image is acquired;
• acquiring, as a representative image of an image group, image data having a month and day that is identical to or approximately the month and day corresponding to the specified image from each of the image groups generated;
• and
• displaying a list of each of the image groups sorted by year and displaying the respective representative image placed at the head of each image group, when the representative image of each image group is acquired.

A program embedded in a non-transitory computer-readable medium, the program comprising:

• a first list displaying module operative to display on a display device a list of thumbnail images of a plurality of image data in a database that stores a plurality of image data to which a shooting timestamp, including the year, month, and day of the shooting, is attached as attribute information;
• an instruction receiving module operative to acquire a thumbnail image, which is among the displayed thumbnail images, as a specified image;
• an image classifying module operative to generate one or a plurality of groups of images by classifying the plurality of respective image data in terms of the respective year when the respective image data are shot, when the specified image is acquired;
• a representative image selecting module operative to acquire, as a representative image of an image group, image data having a month and day that is identical to or approximately the month and day corresponding to the specified image from each of the image groups generated;
• and
• a second list displaying module operative to display a list of each of the image groups sorted by year and operative to display the respective representative image placed at the head of each image group, when the representative image of each image group is acquired.
