Abstract: An augmented reality system may generate an augmented reality environment by projecting images onto various surfaces within a scene. A projection accessory display device (PADD) provides known characteristics for projection, and may be configured to simplify generation and maintenance of the projected image upon the PADD. The PADD may also provide one or more input devices which accept input from a user within the augmented reality environment. The PADD may comprise non-electronic passive components, electronic active components, or a combination thereof.

Abstract: A projection apparatus has an optical device configured to be capable of diffusing coherent light beams, an irradiation unit configured to irradiate the coherent light beams to the optical device so that the coherent light beams scan the optical device, a light modulator that is illuminated by coherent light beams incident on and diffused at respective points of the optical device from the irradiation unit, a projection optical system configured to project a modulated image generated by the light modulator onto a scattering plane, and an intermediate optical system provided between the optical device and the light modulator, configured to restrict an diffusion angle of coherent light beams diffused by the optical device.

Abstract: According to one embodiment, an image processor includes: an acquisitor; a predictor; a corrector. The acquisitor acquires information regarding shape of a projection surface on which a first image is projected, information regarding position of a viewpoint for observing the first image projected on the projection surface, and information regarding position of a projection point for projecting the first image. The predictor predicts a viewable region in which the first image projected on the projection surface is viewable from the viewpoint based on the acquired information regarding the shape, the acquired information regarding the viewpoint, and the acquired information regarding the projection point. The corrector corrects a second image to generate the first image, the second image being set within the viewable region.

Abstract: A system having a finger-wearable sleeve having an IR light-emitting diode (LED), an IR camera; and a controller associated with the IR camera. The controller is configured to communicate with a host computer that utilizes a visual content projector to project visual content onto the screen. And based on signals received from the IR camera (1) trigger a first input functionality in the host computer, wherein the first input functionality is based on a location on the screen where an IR beam from the IR laser impinges, and (2) trigger a second input functionality in the host computer, wherein the second input functionality is based on a location on the screen near where an IR beam from the IR LED is emitted.

Abstract: A method for creating a volumetric display. The method includes projecting a first light type onto a planar projection surface to display first content and, concurrently with projection of the first light type, first projecting a second light type onto the planar projection surface to display second content that at least partially overlays the displayed first content. The method includes second projecting the second light type onto a three dimensional (3D) set of reflective elements, whereby the second content moves between the planar projection surface and the 3D set. The first light type may be non-coherent light and the second light type may be laser light (or coherent light). While projected on the planar projection surface, the coherent light is at a first illumination level that matches or is somewhat greater than the non-coherent light, and a second much higher illumination level is used when projecting onto the 3D set.

Abstract: It is intended to provide a digital planetarium picture-projecting apparatus capable of recording and executing an operation procedure, facilitating recording of the operation procedure, editing the operation procedure, and executing an ad-lib representation when the operation procedure is executed. The digital planetarium picture projecting apparatus comprises an operating portion which accepts an operation by an operator about picture projection, an operation display panel which displays information about picture projection to the operator, a manual process recording portion which records an operation procedure executed to the operating portion, and a control portion which executes picture projection according to the operation procedure recorded in the manual process recording portion, wherein a temporary stop or restart operation by the operator is accepted during recording of the operation procedure by the manual process recording portion.

Abstract: An image projecting apparatus enables the formation of a projected image faithful to original image information by reducing degradation in the projected image due to decrease in imaging performance of a projection optical system. Image information is processed by an image processing device, which includes a first and a second image processor. A light modulating device modulates a flux of light emitted by an illumination optical system based on the processed image information. The modulated flux of light is projected on a screen by a projection optical system. If the image information processed by the first image processor in a pixel region is not within a representable modulation range of the light modulating device, the image information is processed by the second image processor.

Abstract: The invention discloses a method for igniting a lamp of a projector. The method includes steps of: (a) sensing a first temperature difference in response to power-off of the projector; (b) in response to power-on of the projector, detecting an aftercooling time and judging whether it is smaller than a predetermined cooling time, if YES, perform step (c); otherwise, perform step (g); (c) sensing a second temperature difference; (d) judging whether a ratio of the second temperature difference to the first temperature difference is larger than a threshold, if YES, perform step (e); otherwise, perform step (g); (e) calculating a re-cooling time; (f) controlling a fan to operate for the re-cooling time to cool the lamp down; and (g) igniting the lamp.

Abstract: A projection unit 17 effectively corrects out of focus due to a temperature rise. A mirror holding mechanism of a concave mirror 25 has a mirror holder 41 and a mirror holder base 42. The concave mirror 25 is slidably housed in the mirror holder 41.
