Abstract

There is provided a content provision system including an information processing apparatus and a terminal device wherein the information processing apparatus provides a content that includes images respectively captured at discrete capturing locations to the terminal device, the information processing apparatus comprising: a retrieving unit configured to retrieve the content and a position information item associated with the content; and a transmission unit configured to transmit the content and the position information item to the terminal device; the terminal device comprising: a reception unit configured to receive the content and the position information item; and a content reproduction unit configured to reproduce the content by selecting an image to be displayed and displaying a partial area of the selected image, the displayed partial area being extracted from the selected image to show a view in a direction of the designated position for at least one of the images.

First claim

What is claimed is:

1. A content provision system including an information processing apparatus and a terminal device,
the information processing apparatus comprising:
a processor that provides a content that includes a plurality of images respectively captured at discrete capturing locations to the terminal device and retrieves the content from a content storage device for storing the content, and a position information item associated with the content from a position information storage device for storing the position information item, the position information item defining a designated position; and
a transmitter that transmits the retrieved content and the retrieved position information item to the terminal device;
the terminal device comprising:
a receiver that receives the content and the position information item; and
a processor that reproduces the content by successively selecting an image to be displayed from the images included in the content and displaying a partial area of the selected image, the displayed partial area being extracted from the selected image to show a view in a direction of the designated position for at least one of the images that is identified based on a distance between the designated position and a capturing location of the at least one of the images, wherein
the position information item associated with identification information for identifying at least one of the images included in the content is stored in the position information storage device,
the receiver receives the identification information with the position information item,
the processor sets eye directions of images for defining a center of the partial area, at least the eye direction of a first image identified by the identification information being directed to the designated position,
the content includes the first image and a second image displayed after the first image in the reproduction of the content,
the eye direction of the first image is set to be directed to the designated point, and
the eye direction of the second image is set by adjusting an initial eye direction of the second image based on the eye direction of the first image and a distance between a first capturing location corresponding to the first image and a second capturing location corresponding to the second image.

2. The content provision system according to claim 1 , wherein
the receiver of the terminal device further receives a display magnification rate associated with the identification information, and
the processor reproduces the content by displaying the first image magnified or reduced at the display magnification rate.

3. The content provision system according to claim 2 , wherein
the display magnification rate of the second image is set by adjusting an initial display magnification rate of the second image based on the display magnification rate of the first image and the distance between the first capturing location and the second capturing location.

4. The content provision system according to claim 2 , wherein
(A) a first designated point and a second designated point are defined by the position information items,
(B) the content includes the first image, a second image displayed after the first image, and a third image displayed between the first image and the second image in the reproduction of the content,
(C) a distance between a first capturing location corresponding to the first image and the first designated point being less than a first predetermined value, a distance between a second capturing location corresponding to the second image and the second designated point being less than a second predetermined value, a distance between a third capturing location corresponding to the third image and the first designated point being greater than or equal to the first predetermined value, a distance between the third capturing location and the second designated point being greater than or equal to the second predetermined value,
(D) the eye direction of the first image is set to be directed to the first designated point,
(E) the eye direction of the second image is set to be directed to the second designated point, and
(F-1) the eye direction of the third image is set by adding a vector indicating the eye direction of the first image and a vector indicating the eye direction of the second image based on distances between the first capturing location and the third capturing location and the second capturing location and the third capturing location, or
(F-2) the display magnification rate of the third image is set to be a value between the display magnification rate of the first image and the display magnification rate of the second image.

5. The content provision system according to claim 1 , wherein the processor sets a reproduction speed of the first image slower than reproduction speed of other images.

6. The content provision system according to claim 1 , wherein
group information for identifying a group to which the position information item belongs is further stored in the position information storage device, the group information being associated with the position information item,
the transmitter transmits the position information item designated by the group information, and
the processor of the terminal device sets the display range of the image based on the designated position defined by the position information item designated by the group information.

7. The content provision system according to claim 1 , wherein
the processor of the information processing apparatus further detects an object located within a predetermined range around the capturing location of the image included in the content so as to store the position information item of the detected object in the position information storage device, the object being detected based on a map data retrieved from a map data storage device.

8. The content provision system according to claim 1 , wherein
the transmitter of the information processing apparatus further transmits a screen to the terminal device, the position information item or a display magnification rate in the content being set in the screen, wherein
the transmitter acquires the position information item and the display magnification rate input by a user of the terminal device through the screen.

9. A method of a content provision system including an information processing apparatus and a terminal device, the method comprising:
providing, by the information processing apparatus, a content that includes a plurality of images respectively captured at discrete capturing locations to the terminal device,
retrieving, by the information processing apparatus, the content from a content storage device for storing the content, and a position information item associated with the content from a position information storage device for storing the position information item, the position information item defining a designated position, and
transmitting the retrieved content and the retrieved position information item to the terminal device;
receiving, by the terminal device, the content and the position information item, and
reproducing the content by successively selecting an image to be displayed from the images included in the content and displaying a partial area of the selected image, the displayed partial area being extracted from the selected image to show a view in a direction of the designated position for at least one of the images that is identified based on a distance between the designated position and a capturing location of the at least one of the images, wherein
the position information item associated with identification information for identifying at least one of the images includ
