Abstract
One embodiment according to the technique of the present disclosure provides a projection device having a plurality of modes in which relationships between an incidence region and an emission region in an electro-optical panel are different from each other. In the projection device according to one aspect of the present invention, a control unit controls a first mode and a second mode. The first mode is a mode in which a first range of an optical region is the incidence region and a range within the first range is the emission region, and the second mode is a mode in which a second range narrower than the first range of the optical region is the incidence region and a range within the second range is the emission region.
Claims20
A projection device comprising:
- a light source;
- an electro-optical panel having an optical region in which an electro-optical element that controls transmission or reflection of light is provided, the electro-optical panel having an incidence region which is defined in the optical region and on which light from the light source is incident and an emission region which is defined in the optical region and from which the light incident on the incidence region is emitted by the electro-optical element;
- a projection lens that projects the light emitted from the emission region;
- and
- a control unit that controls the electro-optical panel or the light incident on the electro-optical panel from the light source to define the incidence region and the emission region,
- wherein the control unit controls a second mode,
- in a case where at least a part of the optical region is defined as a first range, the second mode is a mode in which a second range narrower than the first range is the incidence region and a range within the second range is the emission region.
