Abstract

A position acquiring unit acquires position information for identifying a position of a projection surface on which a first projecting unit projects an image. A projection information acquiring unit acquires projection information related to the projection performed by a second projecting unit. The controlling unit controls the first projecting unit to project an image on the projection surface based on the position information and the projection information.

First claim

What is claimed is:

1 . A control apparatus comprising:
a position acquiring unit configured to acquire position information for identifying a position of a projection surface on which a first projecting unit projects an image; a projection information acquiring unit configured to acquire projection information related to projection performed by a second projecting unit; and a controlling unit configured to control the first projecting unit to project an image on the projection surface based on the position information and the projection information.

2 . The control apparatus according to claim 1 , wherein the controlling unit corrects an image to be projected by the first projecting unit when the projection surface moves.

3 . The control apparatus according to claim 1 , wherein the controlling unit changes a projecting position where the first projecting unit projects an image when the projection surface moves.

4 . The control apparatus according to claim 1 , further comprising a shape acquiring unit configured to acquire shape information related to a solid having the projection surface, wherein
the controlling unit controls the first projecting unit to project an image on the projection surface based on the position information, the projection information, and the shape information.

5 . The control apparatus according to claim 4 , further comprising a storing unit configured to store the shape information, wherein
the shape acquiring unit acquires the shape information from the storing unit.

6 . The control apparatus according to claim 1 , wherein the projection information indicates a projecting direction of the second projecting unit.

7 . The control apparatus according to claim 1 , wherein an image projected by the first projecting unit is a moving image.

8 . The control apparatus according to claim 1 , wherein the controlling unit determines a projecting position where the first projecting unit projects an image and controls the first projecting unit to project an image on the projecting position based on the position information and the projection information.

9 . The control apparatus according to claim 1 , wherein the projection information indicates a relative position of a projecting direction of the second projecting unit to the projection surface.

10 . The control apparatus according to claim 1 , wherein
the position acquiring unit acquires first relative information indicating a relative position of a projecting direction of the first projecting unit to the projection surface based on the position information, the projection information is second relative information indicating a relative position of a projecting direction of the second projecting unit to the projection surface, and the controlling unit determines a projecting position where the first projecting unit projects an image based on the first relative information and the second relative information and controls the first projecting unit to project an image on the projecting position.

11 . The control apparatus according to claim 1 , wherein the position information is acquired from an image capturing the projection surface.

12 . A control method comprising:
acquiring position information for identifying a position of a projection surface on which a first projecting unit projects an image; acquiring projection information related to projection performed by a second projecting unit; and controlling the first projecting unit to project an image on the projection surface based on the position information and the projection information.

13 . A storage medium readable by a computer and storing a program that instructs a computer to:
acquire position information for identifying a position of a projection surface on which a first projecting unit projects an image, acquire projection information related to projection performed by a second projecting unit, and control the first projecting unit to project an image on the projection surface based on the position information and the projection information.
