A projection system includes an invisible light projector, an imaging unit, an image generator, and a visible light projector. The invisible light projector projects a predetermined invisible light image onto the object via invisible light. The imaging unit captures an image of the invisible light projected from the invisible light projector. The image generator measures a shape of the object based on the image captured by the imaging unit to generate image data showing image content for projection onto the object in accordance with the measured shape. The visible light projector projects the image content shown by the image data onto the object via visible light. The invisible light projector emits pulsed invisible light to project the measurement pattern. The image generator generates the image data based on an image captured in accordance with a timing for the pulsed light emission.

A projection system includes three or more projectors. Each of the projectors includes a projection section that projects image light to form a projection image on a screen. The projectors are so arranged that the three or more projection images projected by the projectors form a tiled image. The projection image projected by any of the projectors and the projection image projected by an adjacent projector form an overlapping area where the projection images overlap with each other, and one of the overlapping areas differs from the other overlapping areas in terms of size.

A projection system includes an illumination light source configured to emit an illumination light beam, a monitor light source configured to emit a monitor light beam, and a projector configured to project both the illumination light beam and the monitor light beam into a projected combined light beam. A first portion of the projected combined light beam is propagated over a first beam path in a first direction, causing an eye of a user to see a display image. A second portion of the projected combined light beam is propagated over a second beam path in a second direction, causing a monitor camera to capture a monitor image. The monitor image is analyzed to determine an orientation or a position of the monitor image. In response to determining that the monitor image is not properly oriented or positioned, an orientation or position of the projector or the illumination image is adjusted.

Systems and methods are provided for automatically controlling zone interactions in a three dimensional virtual environment. A computing device provides a graphical user interface (GUI) to assign zone attributes to a zone, which is a volume of space in the virtual environment. A virtual object is assigned to the zone, as well as an interaction and a responsive operation that follows the detected interaction. The virtual object's position in the virtual environment corresponds to a physical object's position in a physical environment. For example, when the computing system detects that the virtual object has entered or left the zone, according to an assigned interaction, then an assigned operation is executed to control a physical device in the physical environment.

Aspects of the present invention relate to methods and systems for the see-through computer display systems with adjustable-zoom cameras positioned such that their respective capture fields-of-view at least partially overlap at a target distance.

A parameter adjusting method is applied to a projector having an ambient light sensor, a database and a digital micromirror device. The parameter adjusting method includes analyzing a detection signal generated by the ambient light sensor to acquire an environmental light datum, comparing the environmental light datum with a lookup table of the database to compute at least one compensation parameter, and adjusting an amount of reflection light generated by the digital micromirror device in accordance with the at least one compensation parameter for controlling the projector to output a calibrated projection image in response to compensation of the environmental light datum.

A control apparatus includes a control unit that adjusts at least one of a color and luminance of a projection image for each group of the plurality of projection apparatuses based on information on the group and a captured image obtained by imaging projection images of the plurality of projection apparatuses using the pickup apparatus. The control unit acquires each of positions of a plurality of projection areas of the plurality of projection apparatuses based on the captured image, and generates, as the information on the group, information indicating that two projection apparatuses corresponding to a first projection area and a second projection area belong to the same group in a case where a distance between the first projection area and the second projection area among the plurality of projection areas is smaller than a predetermined threshold.

A method of controlling a projector includes projecting an achromatic area image representing a drawing area in which the projector receives drawing using a pointer on a projection surface at a first luminance at a ratio on the projection surface, the ratio being smaller than or equal to a specific ratio to a maximum luminance at which the projector capable of project an image on the projection surface, detecting a position on the projection surface pointed by the pointer while projecting the area image, determining whether or not the position is included in the drawing area, and displaying, by the projector, an area including at least a part of an outline of the drawing area at a luminance higher than the first luminance when it is determined that the position is included in the drawing area.

An electronic device and a control method thereof are provided. The control method of an electronic device includes: projecting, by the electronic device, a first test projection image including at least one marker of a first color while an external device projects a second test projection image including at least one marker of a second color that is different from the first color; obtaining a captured image of projection regions on which the first test projection image and the second test projection image are projected while the projection region on which at least one of the first test projection image or the second test projection image is projected is changed; and identifying an overlapping region between the first test projection image and the second test projection image based on at least one of (1) a third marker of a third color or (ii) the marker of the first color and the marker of the second color, in the captured image, the marker of the third color being the marker of the first color and the marker of the second color overlapping each other, and the third color being different from the first color and the second color.
