Abstract

An image generation system includes an image information acquisition section that acquires image information from an image sensor, a motion information acquisition section that acquires motion information about an operator based on the image information from the image sensor, an object control section that moves an object in a movement area based on the motion information about the operator, and an image generation section that generates an image displayed on a display section. The object control section limits movement of the object so that the object does not move beyond a movement limiting boundary set in the movement area even when it has been determined that the object has moved beyond the movement limiting boundary based on the motion information.

Claims

1. An image generation system comprising:

an image information acquisition section that acquires image information from an image sensor;

a motion information acquisition section that acquires motion information about an operator based on the image information from the image sensor;

an object control section that moves an object in a movement area based on the motion information about the operator; and

an image generation section that generates an image displayed on a display section,

the object control section limiting movement of the object so that the object does not move beyond a movement limiting boundary that is set in the movement area even when it has been determined that the object has moved beyond the movement limiting boundary based on the motion information.

2. The image generation system as defined in claim 1,

the object control section limiting movement of the object so that the object does not move beyond the movement limiting boundary that is set corresponding to a plurality of contact target objects that are contact targets of the object.

3. The image generation system as defined in claim 2,

the plurality of contact target objects being disposed in an object side area with respect to the movement limiting boundary;

and

the object control section limiting movement of the object so that the object does not move beyond the movement limiting boundary that is set to be circumscribed to the plurality of contact target objects.

4. The image generation system as defined in claim 1,

a first movement area and a second movement area being set as the movement area;

and

the object control section moving a first object in the first movement area, moving a second object in the second movement area, and limiting movement of the first object and the second object so that the first object and the second object do not move beyond the movement limiting boundary that is set between the first movement area and the second movement area.

5. The image generation system as defined in claim 4,

the object control section controlling movement of the first object in the first movement area based on the motion information about a first part of the operator, and controlling movement of the second object in the second movement area based on the motion information about a second part of the operator.

6. The image generation system as defined in claim 1,

the object control section limiting movement of the object so that the object does not move beyond a screen-edge movement limiting boundary provided corresponding to an edge of a screen of the display section.

7. The image generation system as defined in claim 6,

the screen-edge movement limiting boundary being provided outside the edge of the screen.

8. The image generation system as defined in claim 7,

a distance between the screen-edge movement limiting boundary and the edge of the screen being smaller than a width of the object.

9. The image generation system as defined in claim 1,

the motion information acquisition section acquiring skeleton information that specifies a motion of the operator as the motion information;

and

the object control section moving the object in the movement area based on the skeleton information.

10. The image generation system as defined in claim 9, further comprising:

a correction section that pertain s a correction process on position information about a bone of a skeleton indicated by the skeleton information,

the object control section controlling the object based on a result of the correction process.

11. The image generation system as defined in claim 10,

the object control section controlling the object based on the corrected position information; and

the image generation section generating an image so that the object is displayed at a display position on a screen corresponding to the corrected position information.

12. The image generation system as defined in claim 10,

the correction section performing the correction process so that a display position of the object when a skeleton of a first operator is in a first state is identical with a display position of the object when a skeleton of a second operator is in the first state.

13. The image generation system as defined in claim 10,

the correction section performing the correction process using physique information about the operator.

14. The image generation system as defined in claim 9, further comprising:

a reliability information acquisition section that acquires reliability information that indicates reliability of the skeleton information,

the image generation section generating an image corresponding to the acquired reliability information as the image displayed on the display section.

15. The image generation system as defined in claim 14,

the image generation section changing a display state of the image displayed on the display section based on the reliability information.

16. An image generation method comprising:

acquiring image information from an image sensor;

acquiring motion information about an operator based on the image information from the image sensor;

moving an object in a movement area based on the motion information about the operator;

generating an image displayed on a display section; and

limiting movement of the object so that the object does not move beyond a movement limiting boundary set in the movement area even when it has been determined that the object has moved beyond the movement limiting boundary based on the motion information.

17. A computer-readable information storage medium storing a program that causes a computer to execute the image generation method as defined in claim 16.
