Abstract

An image capturing device includes: an imaging device to capture a first image; and circuitry to receive a second image from another image capturing device, the second image being captured with the another image capturing device and having an angle of view wider than that of the first image, and control a display to sequentially display the first image, and an image of an area of the second image that is similar to the first image, the image similar to the first image having the degree of similarity to the first image that is equal to or greater than a threshold.

First claim

The invention claimed is:

1. An image capturing device comprising:
an imager to capture a first image; and
circuitry configured to
receive a second image from another image capturing device, the second image being captured with the another image capturing device and having an angle of view wider than that of the first image,
store predetermined area information on a predetermined area of the second image that is similar to the first image, the predetermined area information including a center point and an angle of view of the predetermined area,
calculate display time of an image of the predetermined area based on the predetermined area information,
and
control a display to sequentially display the first image, and the image of the predetermined area of the second image that is similar to the first image for the calculated display time while moving the predetermined area throughout the second image, the image similar to the first image having a degree of similarity to the first image that is equal to or greater than a threshold,
wherein the image of the predetermined area of the second image has a same aspect ratio as the first image and constitutes entire content of display on the display.

2. The image capturing device of claim 1 , wherein, when the area of the second image that is similar to the first image includes a plurality of areas of the second image, the circuitry displays images of the plurality of areas that are similar to the first image, in an order from the image of area having the highest degree of similarity to the image of area having the lowest degree of similarity.

3. The image capturing device of claim 2 , wherein the circuitry further displays an image of at least one area of the second image other than the plurality of areas similar to the first image, which lies between one of the plurality of areas similar to the first image and other one of the plurality of areas similar to the first image, after displaying the image of the one area similar to the first image and before displaying the image of the other area similar to the first image.

4. The image capturing device of claim 3 , wherein
the area of the second image that is similar to the first image includes a part of or entire object that is similar to a part of or entire object in the first image, and
the circuitry sequentially displays images of different areas of the second image to display the entire object.

5. The image capturing device of claim 4 , wherein the circuitry sequentially displays the images of different areas, while moving a display range either 1) from a first position to a second position, or from the second position to the first position, the first position and the second position having different values of imaging direction.

6. The image capturing device of claim 5 , wherein the part of object is a face of a particular person, and
the circuitry moves the display range either from 1) the area showing feet of the particular person to the area showing the face of the particular person, or 2) from the area showing the face of the particular person to the area showing feet of the particular person.

7. The image capturing device of claim 1 , wherein, when the area of the second image that is similar to the first image includes a plurality of areas of the second image, the circuitry is configured to:
receive selection of one image, from among the images of the plurality of areas of the second image that are similar to the first image, and
display the selected image, and images of one or more areas representing an object in the selected image.

8. An image communication system comprising:
the image capturing device of claim 1 ; and
the another image capturing device configured to capture the second image.

9. A method of controlling display of an image, comprising:
obtaining a first image and a second image, the second image having an angle of view wider than that of the first image, the second image having been captured by a second image capturing device different from a first image capturing device that has captured the first image;
storing predetermined area information on a predetermined area of the second image that is similar to the first image, the predetermined area information including a center point and an angle of view of the predetermined area;
calculating display time of an image of the predetermined area based on the predetermined area information;
and
controlling a display to sequentially display the first image, and the image of the predetermined area of the second image that is similar to the first image for the calculated display time while moving the predetermined area throughout the second image, the image similar to the first image having the degree of similarity to the first image that is equal to or greater than a threshold,
wherein the image of the predetermined area of the second image has a same aspect ratio as the first image and constitutes entire content of display on the display.

10. The method of claim 9 , wherein, when the area of the second image that is similar to the first image includes a plurality of areas of the second image, the controlling the display includes:
displaying images of the plurality of areas that are similar to the first image, in an order from the image of area having the highest degree of similarity to the image of area having the lowest degree of similarity.

11. The method of claim 10 , further comprising:
displaying an image of at least one area of the second image other than the plurality of areas similar to the first image, which lies between one of the plurality of areas similar to the first image and other one of the plurality of areas similar to the first image, after displaying the image of the one area similar to the first image and before displaying the image of the other area similar to the first image.

12. The method of claim 11 , wherein
the area of the second image that is similar to the first image includes a part or entire object that is similar to a part of or entire object in the first image, and
the controlling the display includes sequentially displaying images of different areas of the second image to display the entire object.

13. The method of claim 12 , wherein the controlling the display includes sequentially displaying the images of different areas, while moving a display range either 1) from a first position to a second position, or from the second position to the first position, the first position and the second position having different values of imaging direction.

14. A non-transitory recording medium which, when executed by one or more processors, cause the processors to perform a method of controlling display of an image, the method comprising:
obtaining a first image and a second image, the second image having an angle of view wider than that of the first image, the second image having been captured by a second image capturing device different from a first image capturing device that has captured the first image;
storing predetermined area information on a predetermined area of the second image that is similar to the first image, the predetermined area information including a center point and an angle of view of the predetermined area;
calculating display time of an image of the predetermined area based on the predetermined area information;
and
controlling a display to sequentially display the first image, and the predetermined image of the area of the second image that is similar to the first image while moving the predetermined area throughout the second image, the image similar to the first image having the degree of similar
