摘要： The invention refers to a lighting device comprising at least one light emitting diode (LED). The object to provide a lighting device that is capable of providing a light pattern for illuminating an object in 3D imaging, wherein the lighting device is simple and cost-effective to manufacture, while the lighting device may in addition have a very small form factor, is solved in with a lighting device comprising: at least one LED for emitting light towards a light-emitting side; a first grating with a regular pitch having light-blocking sections and light-permeable sections; wherein the first grating is arranged on the light-emitting side to block the passage of light at the light-blocking sections, such that the light passing the light-permeable sections is capable to illuminate an object with a line pattern. The invention further corresponds to a method for producing a lighting device and the use of a lighting device.

摘要： A depth camera assembly (DCA) for depth sensing of a local area includes a structured light generator, an imaging device, and a controller. The structured light generator illuminates the local area with a structured light pattern. The structured light generator includes a programmable diffractive optical element (PDOE) that generates diffracted scanning beams using optical beams. The PDOE functions as a dynamic diffraction grating that dynamically adjusts diffraction of the optical beams to generate the diffracted scanning beams of different patterns. The diffracted scanning beams are projected as the structured light pattern into the local area, wherein the structured light pattern is dynamically adjustable based on the PDOE. The imaging device captures image(s) of at least a portion of the structured light pattern reflected from object(s) in the local area. The controller determines depth information for the object(s) based on the captured image(s).

摘要： A holder for flexible materials which incorporate two arms connected by an elbow. Within the elbow is a tensioning mechanism which, when engaged, tends to press the arm apart. When the tension is released, the holder collapses into an easily stored mechanism. With the arms being variable in length, the range of material dimensions is greatly enhanced. A connector positioned at the elbow permits the holder to be secured to a base and arranged in gangs to address the particular need at the time.

摘要： A method for marking a rotation center on a spindle-less turntable comprises displaying a preview image of a fixed shooting device on a display device, defining the rotation center according to a moving track of a fixture in the preview image, and pointing a light beam from a centering pointer onto the reference center. A light box and a spindle-less turntable suitable for the method are also provided and comprises a round platter, a driving mechanism and at least a centering pointer. The driving mechanism drives the round platter to rotate around a rotation center from the platter edge. The centering pointer is disposed adjacent to the platter edge to emit a light beam toward the platter surface. The light beam continuously passes through a gap between a photographed object and the round platter and points onto the rotation center during the photographed object is put onto the platter surface.

摘要： A special effects system for creating a unique walking character effect or illusion. The character appears to the observer to be a physical character or to have dimensionality rather than being two dimensional. The illusion or effect is achieved by mounting a projector and a thin, vertical, flat screen onto an automated cart or sled. The cart is adapted to roll on a track positioned to run from a backdrop or backwall toward a viewing space in which one or more observers or viewers may be located during system operations. The media (or video file) of the character walking is projected on the projection surface of the screen element with the projector. The sled or cart is triggered to roll forward toward the viewing space as the media is playing so that the projected image appears to be moving and getting closer to the viewer.

摘要： Soft box mount, including a receiver block for receiving an expander strut of a soft box. The receiver block includes, in this order, an inward part, a transverse pivot axis, and an outward part, the outward part of the receiver block being configured to receive a proximal end of the expander strut; and a bar block which is configured to be movable between a first, non-use position, in which the inward part of the receiver block may intrude into a recessed part of the bar block, and a second, use position, in which a non-recessed part of the bar block urges, from a light source side, the inward part of the receiver block to assume a position radially inward of the pivot axis of the receiver block, thereby urging the outward part of the receiver block to assume a position radially outward of the pivot axis of the receiver block.

摘要： Disclosed is an inflatable soft box, which belongs to the technical field of photography and film and television. The present application compromises a flexible case. An inflatable nozzle is provided on the flexible case, and the inflatable nozzle is used to inflate or deflate the flexible case. A soft lamp is provided on the flexible case, and the soft lamp is used to illuminate the flexible case. The structure of the inflatable soft box of the present application is simple. By providing an inflation nozzle on the flexible case, the flexible case is inflated by the inflation nozzle when in use, and the flexible case is inflated; when not in use, the flexible case is deflated by the inflation nozzle, making it easy to carry or move, and convenient for users to use.

摘要： A collapsible light modifier includes a plurality of rods mutually interconnectable one after the other between a first terminal portion and an opposite second terminal portion to form a frame of the light modifier and which can be mutually disconnected to disassemble the frame, and a fabric connected to the frame. Each rod is bound to at least one adjacent rod by a binding element provided between each pair of adjacent rods so as to keep the rods bound to each other when the frame is assembled and when the frame is disassembled, and, both the said first and second terminal portion includes a first end, connected to a respective rod, and an opposite second free end. When the plurality of rods is mutually interconnected, the respective second ends of the first and the second terminal portion can be connected to each other in order to form a closed frame.

摘要： A light source module includes an illumination element and an adjustable light diffusing material. The light source module is configured to receive or generate a control signal for adjusting diffusion of light emitted from the light source module and accordingly adjust an amount of diffusion of light emitted from the light source module. In some embodiments, an adjustable light diffusing material includes a polymer stabilized cholesteric texture (PSCT), a smectic phase liquid crystal, a polymer network liquid crystal (PNLC), or other suitable material. A controller for a light source module may determine a level of diffusion based on a level of inclusion of a wide-angle field of view of a wide-angle lens system or a telephoto field of view of a telephoto lens system in a composite camera field of view that includes a combination of the wide angle field of view and the telephoto field of view. Also, the controller may determine a level of diffusion based or an estimated distance to a scene in a camera field of view that is to be captured.
