Projector and method of controlling projector
First Claim
Patent Images
1. A projector adapted to project a display image on a projection surface, comprising:
- a position detector adapted to detect a position indicated on the projection surface;
a display controller adapted to draw a figure on the display image along a trajectory of an indication position detected by the position detector;
an operating image display section adapted to superimpose an operating image on a part of the display image; and
a projection controller adapted to control a projection configuration of the display image in the case the indication position is located within an operation area where the operating image is superimposed,wherein, while the display controller draws the figure, the display controller continues drawing the figure and the projection controller doesn'"'"'t control the projection configuration even if the indication position is located within the operation area.

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.

5. A method of controlling a projector adapted to project a display image on a projection surface, the method comprising:
-
detecting a position indicated on the projection surface; causing a display controller to draw a figure on the display image along a trajectory of the position detected on the projection surface; superimposing an operating image on a part of the display image; and controlling a projection configuration of the display image in the case the indication position is located within an operation area where the operating image is superimposed, wherein, while the figure is being drawn, the projection configuration isn'"'"'t controlled and the figure continues to be drawn even if the indication position is located within the operation area.
