Abstract
According to an aspect, a mobile electronic device includes an image projecting unit, a distance detecting unit, and a processing unit. The image projecting unit projects an image to a projection plane. The distance detecting unit detects a distance from the image projecting unit to the projection plane. The processing unit causes the image projecting unit to project a projection image including at least part of a reference image in such a manner that a ratio of the projection image to a whole of the reference image is changed based on the change in the distance detected by the distance detecting unit.
Claims27
A mobile electronic device, comprising:
- an image projecting unit for projecting an image to a projection plane;
- a distance detecting unit for detecting a distance from the image projecting unit to the projection plane;
- and
- a processing unit for causing the image projecting unit to project a projection image obtained by clipping a part of a reference image in such a manner that a clipping ratio of the projection image to a whole of the reference image is changed based on the change in the distance detected by the distance detecting unit,
- wherein the projection image in the projection plane after the movement is a different image from the reference image in the projection plane before the movement.
A mobile electronic device, comprising:
- an image projecting unit for projecting an image to a projection plane;
- a movement detecting unit for detecting a movement of the image projecting unit in a direction in which the image projecting unit projects an image;
- and
- a processing unit for causing the image projecting unit to project a projection image obtained by clipping a part of a reference image in such a manner that a clipping ratio of the projection image projected by the image projecting unit to a whole of the reference image is changed based on the movement detected by the movement detecting unit,
- wherein the projection image in the projection plane after the movement is a different image from the reference image in the projection plane before the movement.
A projection system, comprising:
- a mobile electronic device including
- an image projecting unit for projecting an image to a projection plane, and
- an information acquiring unit for acquiring at least one of information for a distance between the image projecting unit and the projection plane and information for a movement of the image projecting unit in a direction along the direction in which the image projecting unit projects an image;
- a processing unit for causing the image projecting unit to project a projection image obtained by clipping a part of a reference image in such a way that a clipping ratio of the projection image to a whole of the reference image is changed based on the information acquired by the information acquiring unit,
- wherein the projection image in the projection plane after the movement is a different image from the reference image in the projection plane before the movement.
An image projecting method, comprising:
- projecting a projection image obtained by clipping a part of a reference image by an image projecting unit;
- detecting a move of the image projecting unit by a detecting unit;
- and
- changing a clipping ratio of the projection image to a whole of the reference image based on the move detected by the detecting unit,
- wherein the projection image in the projection plane after the movement is a different image from the reference image in the projection plane before the movement.
