Abstract
There is provided a projector having a projecting unit, a projecting system which projects video onto a projection surface by use of the projecting unit, a projecting direction judgment system which judges a projecting direction of the projecting system, and a menu image generating system which generates a menu image, as video generated in the projector as the video to be projected by the projecting system, so that the menu image suits the projecting direction judged by the projecting direction judgment system.
Claims20
A projector, which is configured to project video including at least one of a main image and a subsidiary menu image for an operation menu onto a projection surface, comprising:
- a projecting unit;
- a projecting system which projects the video onto the projection surface by use of the projecting unit;
- an attitude detecting system which judges an attitude of the projector being installed;
- and
- a menu image generating system which generates menu image data representing the menu image according to the detected attitude of the projector and outputs the generated menu image data to the projecting unit to have the menu image based on the generated menu image data to be projected from the projection unit.
A projector comprising:
- a housing which is configured to have an opening facing toward a projection surface;
- a projecting system which is installed in the housing and optically projects video onto the projection surface via the opening;
- a projecting direction detecting system which detects a projecting direction of the projecting system;
- and
- a video control system which rotates the video to control an orientation of the video, optically projected by the projecting system, on the projection surface based on the projecting direction detected by the projecting direction detecting system.
A projector which is configured to emit light from a projecting unit in a projecting direction, comprising:
- an attitude detecting system which detects an attitude of the projecting unit;
- and
- a light amount control system which controls the emission of light from the projecting unit so as to reduce the light emission unless the attitude detected by the attitude detecting system is a preset targeted attitude.
