Abstract

A display terminal comprising circuitry that displays a first predetermined-area image on a display screen, the first predetermined-area image representing a predetermined area in a first wide-view image having been captured at a given location on a first date and time; and displays a second predetermined-area image on the display screen, the second predetermined-area image being related to the predetermined area in a second wide-view image, the second wide-view image having captured at the given location on a second date and time different from the first date and time.

First claim

The invention claimed is:

1. A display terminal, comprising:
circuitry configured to:
display a first area image on a display screen, the first area image representing an area in a first wide-view image having been captured at a location on a first date and at a first time;
specify the area in a second wide-view image using point-of-view information used to display the first area image, the second wide-view image having been captured at the location on a second date and at a second time different from the first date and the first time; and
display a second area image on the display screen, the second area image being related to the specified area in the second wide-view image.

2. The display terminal according to claim 1 , wherein the circuitry is further configured to:
receive a shift of a virtual point of view for the first area image displayed on the display screen; and
change a display of the second area image in accordance with a change in the area, the change in the area being made based on the shift of the virtual point of view received for the first area image.

3. The display terminal according to claim 1 , wherein the circuitry is further configured to:
receive a shift of a virtual point of view for the second area image displayed on the display screen, and
change a display of the first area image in accordance with a change in the area, the change in the area being made based on the shift of the virtual point of view received for the second area image.

4. The display terminal according to claim 1 , wherein the first wide-view image and the second wide-view image were captured are a same position or positions within a predetermined distance.

5. The display terminal according to claim 1 , wherein the first wide-view image is a currently captured image, and the second wide-view image is a recorded previous image.

6. The display terminal according to claim 1 , wherein the first wide-view image and the second wide-view image are recorded previous images.

7. A communication system, comprising:
an information processing system to distribute a wide-view image; and
a display terminal to receive and display the wide-view image, wherein
the information processing system includes first circuitry configured to distribute a first wide-view image and a second wide-view image, the first wide-view image and the second wide-view image having been captured at a location on different dates and at different times, and
the display terminal includes second circuitry configured to:
display a first area image on a display screen, the first area image representing an area in the first wide-view image;
specify the area in the second wide-view image using point-of-view information used to display the first area image, the second wide-view image having been captured at the location on a second date and at a second time different from the first date and the first time; and
display a second area image on the display screen, the second area image being related to the specified area in the second wide-view image.

8. A display method, comprising:
displaying a first area image on a display screen, the first area image representing an area in a first wide-view image having been captured at a location on a first date and time;
specifying the area in a second wide-view image using point-of-view information used to display the first area image, the second wide-view image having been captured at the location on a second date and at a second time different from the first date and the first time; and
displaying a second area image on the display screen, the second area image being related to the specified area in the second wide-view image.
