    摘要： Die Erfindung bezieht sich auf einen Realbild-Auflichtprojektor, bestehend aus einem Gehäuse mit einer ebenen durchsichtigen Objektauflage zum Auflegen des Objekts und zum Durchlassen des von mindestens einer Lichtquelle ausgehenden Lichtes, mit einer Projektionslinse zum Zusammenführen der vom Objekt ausgehenden Reflektionsstrahlen zur Erzeugung eines Objektbildes auf einer Bildwand außerhalb des Projektors, und gegebenenfalls mit einem Hilfsspiegel.
    Um bei geringen räumlichen Abmessungen eine gleichmäßige, optimale Ausleuchtung des Objekts zu erreichen und störendes Reflexlicht zu vermeiden, ist die Objektauflage (2) an ihrer dem Objekt (4) abgewandten Seite zumindest in einem vorgegebenen Bereich (10) mit einer Vielzahl Mikroprismen (11) versehen.

    摘要： Disclosed herein is provided is a visual presenter having a head structure capable of changing a photographing direction, the visual presenter including a base fixed to a floor by applying weight to prevent the presenter from falling down, a head part having one end provided with a camera lens facing the floor, a support part connecting the head part and the base and extending upward from the base to position the head part at a height of a learner's face, and a photographing mode switching module disposed adjacent to the camera lens and configured to switch between a learner photographing mode and a study material photographing mode without requiring manipulation of the head part.

    摘要： The present invention provides a laser projection clock, comprising a driving device, one or a plurality of pointer light source device, and one or a plurality of grating. The driving device comprises one or a plurality of rotating shafts and power elements for driving the one or plurality of the rotating shafts to rotate at different speeds respectively. The one or plurality of pointer light source devices is configured on one side of the driving device to each output a laser beam. The one or plurality of gratings is configured on the one or a plurality of rotating shafts in a one-on-one manner in order to be rotated by the one or plurality of rotating shafts respectively. The grating has an indication pattern, and the one or plurality of laser beams are projected to a projection plane through the one or a plurality of indication patterns of the one or plurality of gratings to form one or plurality of laser indications respectively.

    摘要： In one example, a projection capture system includes: a digital camera, a projector, and a mirror housed together as a single unit in which, when the unit is deployed for use with a work surface: the camera is positioned above the projector; the projector is positioned below the camera; and the mirror is positioned above the projector and configured to reflect light from the projector into the camera capture area. In one example, a projection capture method includes: establishing a camera capture area within which a camera can capture an image of an object; establishing a projector display area overlapping the capture area and into which a projector can project light; lighting the camera capture area with the projector; and positioning a specular glare spot from the projector lighting outside the camera capture area.

    摘要： A filter apparatus (1) is a filter apparatus (1) that transmits light emitted by a light source (a lighting apparatus (100)), and the filter apparatus (1) includes a simulated object (20) that receives the light emitted by the light source, a driving device (40) that mechanically moves the simulated object (20), and a first lens (31) that transmits the light emitted by the light source and having passed through the simulated object (20). The filter apparatus (1) projects, onto an illumination surface, a projection image of fluctuation of light and shadow formed by the light emitted by the light source and having passed through the simulated object (20) and the first lens (31).
