Abstract
A projector includes: a projection unit projecting a projection image onto a projection surface where an object is located, the object defining a projection area where the projection image should be projected; an image pickup unit picking up an image of the projection surface and thus generating picked-up image information representing a picked-up image; an object detection unit detecting the object, based on the picked-up image information; and a projection control unit controlling a brightness of the projection image, based on a result of detection of the object.
Claims13
A projector comprising:
- a projection unit configured to project a projection image onto a projection surface where a plurality of objects are attached, the plurality of objects defining a projection area where the projection image is to be projected;
- an image sensor configured to detect an image of the projection surface and generate detected image information representing the detected image;
- and
- a processor configured to:
- perform a detection operation for each object of the plurality of objects based on the detected image information;
- and
- control a brightness of the entire projection image based on whether at least one object of the plurality of objects is not detected by the detection operation.
A method for controlling a projector, the method comprising:
- projecting a projection image onto a projection surface where a plurality of objects are attached, the plurality of objects defining a projection area where the projection image is to be projected;
- detecting an image of the projection surface and generating detected image information representing the detected image;
- performing a detection operation for each object of the plurality of objects based on the detected image information;
- and
- controlling a brightness of the entire projection image based on whether at least one object of the plurality of objects is not detected by the detection operation.
