Abstract: An adjustable carrier structure for a lamp is described. Said adjustable carrier structure comprises an optical component carrier on which an optical component may be fastened, a coupling device for fastening the carrier structure on the lamp, and at least one threaded spindle. The latter comprises a first threaded spindle end that is mounted in an axially-fixed and non-rotatable manner on the optical component carrier, and is connected to the coupling device via a threaded socket that cooperates with the threaded spindle. In this case, the threaded socket is connected to the coupling device in an axially-fixed and rotatable manner. The threaded spindle extends essentially parallel to an optical axis of the adjustable carrier structure. A distance may be set between the first threaded spindle end and the coupling device by means of rotating the threaded socket. Moreover, a lamp having a carrier structure of this type is proposed.

Abstract: A spotlight (1) is described for illuminating a film, studio, stage, event, and/or theatre environment. The spotlight comprises: a reflector arrangement (11) having a reflective inner surface (113), which delimits a reflector interior (114); a number of passive light guides (12) having feed points (121), which are arranged outside the reflector interior (114), and having light output points (122), which are arranged inside the reflector interior (114).

Abstract: A method of compressing image data is described in which a difference value is formed for a respective pixel, said difference value corresponding to a predetermined relation between the pixel value and the estimated pixel value of the respective pixel and being represented by a first binary word that has a first length. The first binary word is encoded by at least one second binary word that has a second predetermined length. the first length is compared with the second length to determine whether the first length is smaller than the second length, with the first binary word otherwise being completely encoded by a single second binary word when the first length is smaller than the second length, and with the first binary word otherwise being completely encoded by a plurality of second binary words. A method of decompressing image data is furthermore described that corresponds to a reversal of the compression method.

Abstract: A camera viewfinder comprises an electronic display apparatus that is configured for the display of images that are recorded by an image sensor of an electronic camera. The camera viewfinder further comprises two mirrors for reflecting the images displayed by the display apparatus, of which at least one mirror is a free-form surface mirror whose reflective surface is formed as a free-form surface that does not have any continuous translation symmetry or rotational symmetry. At least one of the free-form surface mirrors is adjustable to at least partially compensate a vision defect of a user.

Abstract: An object simulation unit for testing a camera objective has an optical axis and has a front side with respect to the optical axis at one side. The object simulation unit comprises a light exit surface at the front side of the object simulation unit, a coupling device that is adapted to couple the front side of the objection simulation unit to a light entry side of a camera objective, and a light beam generation device that has at least one light source and that is adapted to generate at least one light beam that passes through the light exit surface such that the at least one light beam apparently starts from a virtual object located at a distance from the light exit surface that is larger than the distance between the light beam generation device and the light exit surface. A diagnostic system may comprise such an object simulation unit.

Abstract: A camera system includes a camera unit for capturing still or moving images of an object. The camera unit is adjustable in respect of at least one parameter relevant to the capture of the images based on a measurement signal. A measuring unit captures a distance between the object and the camera unit and includes a laser transceiver for emitting a laser signal and receiving a laser signal reflected by the object. An evaluation unit coupled to the laser transceiver provides the measurement signal. The measurement signal indicates the distance between the object and the camera unit. A lens system has at least two spaced apart lenses. The laser signal emitted by the laser transceiver passes through the lens system. At least one of the lenses is arranged in movable fashion such that the distance between the lenses is variably adjustable parallel to the laser signal transmission direction.

Abstract: A light-producing assembly for a spotlight for illuminating film, studio, stage, event and/or theater surroundings comprises a carrier, on which an LED arrangement with a multiplicity of LEDs is arranged. Here, the LEDs are provided by N>2 different color types. The assembly also comprises a line system for supplying power to the LEDs, which comprises a multiplicity of lines with N line types, wherein lines of different line types cross in crossing regions and the crossing regions lie outside of a vertical projection surface of footprint sides of the LEDs in a vertical plan view of the carrier front side. Further, the assembly comprises an optical unit coupled to the LED arrangement, said optical unit spanning the totality of the LEDs. Moreover, a spotlight comprises such a light-producing assembly.
