Abstract
A projector system includes: a position detecting unit that detects a pointed position of a pointer on a projection surface; a drawing unit that performs drawing on the projection surface according to the pointed position detected by the position detecting unit; a height detecting unit that detects a height of a user of a projector; and a display changing unit that changes, according to the user's height detected by the height detecting unit, at least one of a shape of the image projected onto the projection surface and a display position of the image on the projection surface.
Claims8
A projector system that modulates light from a light source via a modulating unit and projects an image onto a projection surface, comprising:
- a position detecting unit that detects a pointed position of a pointer on the projection surface;
- a drawing unit that performs drawing on the projection surface according to the pointed position detected by the position detecting unit;
- a height detecting unit that detects a height of a user of a projector;
- and
- a display changing unit that changes, according to the user's height detected by the height detecting unit, a shape of the image projected onto the projection surface or a display position of the image on the projection surface.
A control method of a projector system that modulates light from a light source and projects an image onto a projection surface, comprising:
- detecting a position pointed to by a pointer on the projection surface;
- performing drawing on the projection surface according to the detected position;
- detecting a user's height;
- and
- changing, according to the detected user's height, a shape of the image projected onto the projection surface or a display position of the image on the projection surface.
