Abstract
An image display method includes displaying, on a display surface, a first image based on first image data from a first input source; and establishing a correspondence between a feature of a first marker and the first input source when it is detected that the first marker is placed in a detection area included in the display surface while the first image is displayed on the display surface.
Claims20
An image display method comprising:
- displaying, on a display surface, a first image based on first image data from a first input source;
- and
- establishing a first correspondence between a feature of a first marker and the first input source when it is detected that the first marker is placed in a detection area included in a detection surface while the first image is displayed on the display surface.
A projector comprising:
- a projection device including
- a light source,
- a modulation device modulating light emitted from the light source to emit image light, and
- an optical projection system projecting the image light onto a display surface;
- an image capture device outputting captured image data by capturing an image of a detection area included in a detection surface;
- and
- at least one processor programmed to
- project a first image based on first image data inputted from a first input source, using the projection device, and
- establish a first correspondence between a feature of a first marker and the first input source when it is detected that the first marker is placed in the detection area, based on the captured image data, while the first image is projected.
