Abstract
A projection device includes: a plate shaped member that is thermally conductive; a light emitting element that is disposed upon the plate shaped member and emits light; a bending member that bends light from the light emitting element into an orientation parallel to the plate shaped member; a modulation element that modulates light bent by the bending member; and a polarized light separation element that bends light modulated by the modulation element into an orientation going away from the plate shaped member.
Claims3
An electronic device, comprising:
- a projector that is capable of projecting an image on projection surfaces having different orientations by changing an orientation of the image;
- a sensor that detects attitudes of the electronic device corresponding to the projection surfaces having different orientations;
- a control unit that determines a setting attitude of the electronic device for image projection based upon an output of the sensor and controls the orientation of the image for projection onto each projections surface when the determined setting attitude corresponds to that projection surface.
