Abstract
A projector includes a projection lens, a first imaging section adapted to take an image of the projection surface, and a second imaging section adapted to take an image of the projection surface with a field angle wider than a field angle of the first imaging section. The first imaging section is disposed at a first distance from an optical axis of the projection lens in a direction perpendicular to the optical axis, and the second imaging section is disposed at a second distance longer than the first distance from the optical axis of the projection lens in the direction perpendicular to the optical axis.
Claims6
A projector adapted to project an image on a projection surface, comprising:
- a projection lens;
- a first imaging section adapted to take an image of the projection surface;
- and
- a second imaging section adapted to take an image of the projection surface with a field angle wider than a field angle of the first imaging section,
- wherein the first imaging section is disposed at a first distance from an optical axis of the projection lens in a direction perpendicular to the optical axis, and
- the second imaging section is disposed at a second distance longer than the first distance from the optical axis of the projection lens in the direction perpendicular to the optical axis.
