A method for aligning and merging contents from multiple collaborative workstations. Collaborative workstations are multiple workstations that contribute respective contents to be combined into a single computer-generated output. The content generated from each collaborative workstation is the collaborative content. Individual collaborative content is created from each workstation by a user drawing on a piece of paper that is placed on a workspace surface of the workstation. Collaborative contents contributed by multiple workstations are aligned such that a combined product (i.e., a single computer-generated output) including both virtual and physical content appears to be collaboratively drawn by multiple users on a single piece of paper.

An imaging system including a front aperture, two or more refractive lens elements mounted in a lens barrel, and a photosensor. One or more of the components of the imaging system (e.g., the aperture, lenses, lens groups, and/or photosensor) are tilted with respect to each other and/or with respect to a center (or mechanical) axis of the imaging system to compensate for effects including but not limited to keystone distortion, resolution non-uniformity, and gradient blur that result from tilt of an object in the field of view of the camera with respect to the center axis of the camera.

A projection device, including an illumination system, a control element, a driving element, a light valve, and a projection lens, is provided. The illumination system includes multiple light sources for providing multiple light beams to be combined into an illumination light beam. The driving element respectively drives the light sources in a first mode or a second mode, so that the light beams have respective luminous brightness, and the driving element is switched from the first mode to the second mode according to a first signal. The control element provides the first signal to the driving element according to an optical state or a time state of the projection device. The light valve is adapted to convert the illumination light beam into an image light beam. The projection lens is adapted to project the image light beam out of the projection device.

The invention provides a method for light projection in the interior of an automotive vehicle. The method includes sensing, by at least one sensor, the presence of an object or person in the interior of the vehicle, wherein the sensor comprises a plurality of image sensing devices. A protection zone is defined by using the data of the at least one sensor, thus obtaining a three-dimensional protection zone. A first light pattern is projected with a first pattern zone by means of a first projector associated to a first image sensing device. A second light pattern is projected with a second pattern zone by means of a second projector associated to a second image sensing device, wherein the first pattern zone and/or the second pattern zone are projected over the protection zone and wherein the light pattern forms a projected image on an interior surface of the automotive vehicle.

A head up display (HUD) system includes: a laser; a liquid crystal on silicon (LCoS) panel configured to modulate light output by the laser; a modulator control module configured to, during each predetermined period: apply power to the LCoS panel for a first predetermined ON period; and disconnect the LCoS panel from power for a remainder of the predetermined period; and a laser control module configured to, during each predetermined period: when a temperature of the LCoS panel is less than a predetermined temperature: apply power to the laser for a second predetermined ON period while power is applied to the LCoS panel and after the modulator control module begins applying power to the LCoS panel, where the second predetermined ON period is less than the first predetermined ON period; and disconnect the laser from power for the remainder of the predetermined period.

A system for measuring speckle contrast includes: a head up display (HUD) system configured to output a predetermined image and having a first pixels per degree (PPD); an imaging colorimeter: having a field of view; positioned such that the predetermined image is in the field of view; having a second PPD that is at least 2.2 times greater than the first PPD of the HUD system; and configured to capture an image including the predetermined image; and a speckle contrast module configured to determine a speckle contrast of the HUD system based on the image.

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.

An image processing device includes: an image acquisition unit that acquires first and second image data for projecting the image from the first and second projection units respectively; a superimposed region information acquisition unit that acquires information on a superimposed region between the projection range of the first projection unit and the projection range of the second projection unit; a first image processing unit that performs first image processing on a first portion in the first image data corresponding to the superimposed region; a second image processing unit that performs second image processing on a second portion in the second image data corresponding to the superimposed region; and an output unit that outputs the first image data after the first image processing as image data for the first projection unit and outputs the second image data after the second image processing as image data for the second projection unit.
