Projector and method for controlling the same
A projector includes: an image modulation section that modulates light emitted from a light source in accordance with a video signal to form an optical image; a projection section that enlarges and projects the optical image; a drawing area setting section that sets a drawing area within an image modulation area where the light is modulated to form the optical image, the drawing area being an area where a template image is drawn; and a template image generating section that generates the template image to be drawn in the drawing area.
1. A projector comprising:
an image modulation section that modulates light emitted from a light source in accordance with a video signal to form an optical image;
a projection section that projects the optical image on a projection surface;
a drawing area setting section that sets a drawing area within a specified portion of an image modulation area where the light is modulated to form the optical image, the portion of the image modulation area within which the drawing area is set being specified by drawing area specifying information provided by a user, the drawing area being an area where a template image is drawn; and
a template image generating section that generates the template image to be drawn in the drawing area,
wherein
the template image generating section does not generate the template image to be drawn in a portion of the image modulation area that is outside the drawing area, and
the drawing area specifying information provided by the user specifies one or more positions within the drawing area and comprises a plurality of area specifying marks that specify a plurality of points on an edge of the drawing area.
2. The projector according to claim 1 ,
further comprising an imaging section that captures an image projected through the projection section,
wherein the drawing area setting section sets the drawing area based on drawing area specifying information contained in the image captured by the imaging section.
3. The projector according to claim 1 ,
wherein the drawing area setting section sets the drawing area in accordance with drawing area specifying operation for specifying the drawing area.
4. The projector according to claim 1 ,
wherein the drawing area setting section sets the shape of the drawing area in accordance with an input of shape specifying information for specifying the shape of the drawing area.
5. The projector according to claim 1 ,
wherein the template image generating section generates the template image in accordance with the size of the drawing area.
6. The projector according to claim 1 ,
wherein the template image generating section generates the template image in accordance with an input of type specifying information for specifying the type of the template image.
7. The projector according to claim 1 , wherein the one or more area specifying marks are handwritten on the projection surface.
8. The projector according to claim 3 , wherein the area specifying marks are drawn on the projection surface by the drawing area specifying operation.
9. A method for controlling a projector including an image modulation section that modulates light emitted from a light source in accordance with a video signal to form an optical image and a projection section that projects the optical image on a projection surface, the method comprising:
setting a drawing area within a specified portion of an image modulation area where the light is modulated to form the optical image, the portion of the image modulation area within which the drawing area is set being specified by drawing area specifying information provided by a user, the drawing area being an area where a template image is drawn; and
generating the template image to be drawn in the drawing area,
wherein
the template image is not generated to be drawn in a portion of the image modulation area that is outside the drawing area, and
the drawing area specifying information provided by the user specifies one or more positions within the drawing area and comprises a plurality of area specifying marks that specify a plurality of points on an edge of the drawing area.
10. The method according to claim 9 , further comprising:
capturing an image projected through the projection section,
wherein the drawing area is set based on drawing area specifying information contained in the image captured by the imaging section.
11. The method according to claim 9 , wherein
the drawing area is set in accordance with drawing area specifying operation for specifying the drawing area.
12. The projector according to claim 9 ,
wherein the shape of the drawing area is set in accordance with an input of shape specifying information for specifying the shape of the drawing area.
13. The projector according to claim 9 ,
wherein the template image is generated in accordance with the size of the drawing area.
14. The projector according to claim 9 ,
wherein the template image is generated in accordance with an input of type specifying information for specifying the type of the template image.
15. The projector according to claim 9 , wherein the one or more area specifying marks are handwritten on the projection surface.
16. The projector according to claim 11 , wherein the area specifying marks are drawn on the projection surface by the drawing area specifying operation.
