Image display method and device, image display system, server, program, and recording medium

An image display device for displaying, after imaging, a plurality of image data each relating to attribute data, comprising:

• a reference image disposition section that disposes a plurality of reference image objects each corresponding to each of the plurality of image data at a position based on any one of the corresponding attribute data in one virtual horizontal plane in a virtual three-dimensional (3D) space;
• a data selection section that selects one or more of the image data from the plurality of image data;
• a viewing image disposition section that disposes a viewing image object for indication of the selected image data at a position of any of the corresponding reference image objects moved in a direction of a normal to the virtual horizontal plane, a distance of the viewing image object from the virtual horizontal plane is determined based on the other of the corresponding attribute data;
• a field of view setting section that sets a field of view in the virtual 3D space;
• an imaging section that images the virtual 3D space in the field of view set in the field of view setting section, the disposing of the viewing image object and the imaging are performed at predetermined time intervals;
• and
• a calculating section that calculates a path along which the viewing image object is disposed at the respective time intervals, and which swings around the position of any of the corresponding reference image objects moved in the direction of the normal to the virtual horizontal plane, a swing width or a swing cycle of the path is determined based on the other of the corresponding attribute data.

A server in an image display system for displaying over a network, after imaging, a plurality of image data each relating to attribute data, comprising:

• a memory region that generates a virtual three-dimensional (3D) space;
• a reference image disposition section that disposes a reference image object for indication of each of the plurality of image data at a position based on any one of the corresponding attribute data in one virtual horizontal plane in the virtual 3D space;
• a viewing image disposition section that disposes, at a first predetermined time interval, a viewing image object for indication of the selected image data at a position of any of the corresponding reference image objects moved in a direction of a normal to the virtual horizontal plane;
• an imaging section that images, at a second predetermined time interval, the virtual 3D space in the field of view set in the field of view setting section;
• a distance determining section that determines a distance of the viewing image object from the virtual horizontal plane based on the other of the corresponding attribute data, the disposing of the viewing image object and the imaging are performed at predetermined time intervals;
• and
• a calculating section that calculates a path along which the viewing image object is disposed at the respective time intervals, and which swings around the position of any of the corresponding reference image objects moved in the direction of the normal to the virtual horizontal plane, the calculating section calculates a swing width or a swing cycle of the path that is determined based on the other of the corresponding attribute data.
