Abstract
A projector includes a projection unit configured to emit projected light, a first projection unit configured to form an image in an aerial projection region from a first part of the projected light, and a second projection unit configured to form an image on a real projection surface from a second part of the projected light, the second part being different from the first part.
Claims11
A projector comprising:
- a projection unit configured to emit projected light;
- a first projection unit configured to form an image of a first part of the projected light in an aerial projection region;
- and
- a second projection unit configured to form an image of a second part of the projected light, which is different from the first part, on a real projection surface,
- wherein the real projection surface of the second projection unit comprises a display surface of a first transmission-type screen,
- wherein the first projection unit comprises a second transmission-type screen on which the projected light from the projection unit is projected and a spatial projection microlens array on which image light for an image which is displayed on a display surface of the second transmission-type screen is incident, and
- wherein the second projection unit comprises the first transmission-type screen which is disposed on an axis of projected light of the second part of the projected light so that the projected light of the second part is projected on the first transmission-type screen.

A projection method comprising:
- projecting a first part of projected light emitted from a projection unit on an aerial projection region using a first projection unit;
- and
- projecting a second part of the projected light, which is different from the first part, on a real projection surface using a second projection unit,
- wherein the real projection surface of the second projection unit comprises a display surface of a first transmission-type screen,
- wherein the first projection unit comprises a second transmission-type screen on which the projected light from the projection unit is projected and a spatial projection microlens array on which image light for an image which is displayed on a display surface of the second transmission-type screen is incident, and
- wherein the second projection unit comprises the first transmission-type screen which is disposed on an axis of projected light of the second part of the projected light so that the projected light of the second part is projected on the first transmission-type screen.
