Abstract

A projector can control a function in accordance with an operation of indicating a position if the operation is performed in a state in which an image is displayed. The projector projects an image on a screen based on a supply image supplied by an image source. The projector detects a position indicated on the screen using a position detection unit, and if the indication position detected is located within the operation area set previously, the projector controls the projection configuration of the image using a control section.

Claims

1. A projector adapted to project an image on a projection surface based on a supply image supplied by an image source, comprising:

a position detector adapted to detect a position indicated on the projection surface; and

a projection controller adapted to control a projection configuration of the image in the case an indication position detected by the position detector is located within a predetermined operation area.

2. The projector according to claim 1, further comprising:

a processing section adapted to perform a process based on the indication position detected by the position detector,

wherein either of the process by the processing section and the control by the projection controller is performed in the case the indication position detected by the position detector is located within the predetermined operation area.

3. The projector according to claim 2, wherein

the processing section performs at least one of

a process of generating an additional image to be projected on the projection surface together with the image, and

a process of outputting information including the indication position detected by the position detector to an external device based on the indication position detected by the position detector.

4. The projector according to claim 2,

wherein the position detector detects the indication position indicated on the projection surface by the indication body,

the position detector includes an operation detector adapted to detect an operation of an indication body, and

in the case the operation of the indication body is detected by the operation detector when the indication position detected by the position detector is located within the operation area, the control by the projection controller is performed.

5. The projector according to claim 2, wherein

the position detector detects the indication position indicated on the projection surface by an indication body, and an operation of the indication body, and

in the case the operation of the indication body is detected by the position detector when the indication position detected by the position detector is located within the operation area, the control by the projection controller is performed.

6. The projector according to claim 1, further comprising:

an operating image display section adapted to project an operating image adapted to perform an instruction related to a projection configuration of the image so as to overlap the image,

wherein a display area of the operating image is set in the operation area.

7. The projector according to claim 6, wherein

the operating image display section projects the operating image, which is adapted to instruct at least one of processes of expansion, contraction, translation, and rotation of the image projected on the projection surface, on the projection surface, and

the projection controller performs a process corresponding to the operating image overlapping the indication position detected by the position detector to change the projection configuration of the image.

8. The projector according to claim 1, wherein

the operation area is set to an area outside a range in which the image is projected on the projection surface, and within a range in which the indication position can be detected by the position detector.

9. A method of controlling a projector adapted to project an image on a projection surface based on a supply image supplied by an image source, the method comprising:

detecting a position indicated on the projection surface; and

controlling, in the case the indication position detected is located within a predetermined operation area, a projection configuration of the image.
