An image projection device which can correctly discern content of touch operation when a user performs various kinds of touch operation on an image projected on a projection screen is provided. An imaging unit is configured to image the image projected on the projection screen and acquire image data. A reference data generating unit is configured to generate reference data specifying a position and a size of the image projected on the projection. An image data extracting unit is configured to extract image data in which a finger or a pointer with which a user performs operation on the image projected on the projection screen exists is focused in the image data obtained by the imaging unit. A position data generating unit is configured to generate position data for specifying a position of the finger or the pointer in the imaging range of the imaging unit.

In a projector system including a plurality of projector apparatuses each projecting a picture onto a curved screen of transmissive type having a convex rear side as viewed from a user, a control unit divides an input picture into a plurality of pictures, providing an overlapping region between pictures, and supplies a plurality of divided pictures to the plurality of projector apparatuses, respectively. Optical axis of light projected by the plurality of projector apparatuses intersect at a position farther than a central point of the curved screen, as viewed from the plurality of projector apparatuses.

Universally adjusting Ultra Short Throw (UST) projector credenza having a sliding UST compartment allowing for the cabinet to lie flush or near flush with a forward wall. The UST compartment expands out to a predetermined position to accommodate projecting images onto 100+ inch screens above. Each UST compartment comes with a cross-drilled and ventilated floating shelf that can be adjusted in three dimensions withing the compartment to allow adjustments. Ventilation holes in the shelf aerate the projector without obstructing ventilation. The UST compartment may have a low iron pane of glass over the projector to make it more discrete and hidden, but does not obstruct the image or color of the projected image passing through it in any way.

To provide a new method for displaying a video image on a whole circumference screen. Provided is an image display device including: an emission unit configured to emit image light along a predetermined axis; a screen arranged over a whole circumference around the predetermined axis and having a cylindrical shape with the predetermined axis as a substantially central axis; and an optical unit arranged to face the emission unit with the predetermined axis as a reference, and configured to control an incident angle of the image light emitted by the emission unit, the incident angle being with respect to the screen, in which a video image displayed by the image light incident on the screen is simultaneously displayed over a whole circumference around the predetermined axis.

This disclosure relates to an automotive glass display. An example vehicle includes a projector configured to project light, and a glass panel including a first layer of glass, a second layer of glass, a first layer of polyvinyl butyral (PVB), and a second layer of material. The first layer of PVB is configured to diffuse light from the projector, and the second layer of material is configured to reduce glare. Other example glass panel arrangements are also disclosed.
