摘要
A background display device for a virtual image recording studio that is configured to display, behind a real subject, a representation of a virtual background for a camera recording comprises at least one panel having a plurality of actively illuminating picture elements. The picture elements form a two-dimensional arrangement that extends along a first direction of extent and a second direction of extent oriented perpendicular thereto, wherein a respective spacing, measured along the second direction of extent, of the picture elements from a first reference line that extends rectilinearly along the first direction of extent varies irregularly along the first direction of extent.

The invention relates to a background display device for a virtual image recording studio that is configured to display, behind a real subject, a representation of a virtual background for a camera recording.
Such background display devices can in particular be provided to display in an image recording studio a landscape or an environment in which a recording is to be made by an associated camera and which forms a virtual background for a scene to be recorded. The image recording studio, for example, can be a film studio for recording moving image sequences or a photo studio in which individual images or still images are recorded. In general, such a recording can include local storage of image data or a transmission to a remote location (e.g. Broadcast, Streaming). In the virtual image recording studio, a virtual background or a virtual environment can thus be created in which an actor can move around during a moving image recording, or it can form a background for a still image recording. The virtual background mentioned in the present context therefore comprises image information that represents a background subject and whose representation can be directly recorded by an associated camera as an apparently real environment of a (foreground) scene. The representation of the virtual background “behind” a real subject is to be understood comprehensively in this context since the virtual environment can also be provided above or below the real subject.
權(quán)利要求
The invention claimed is:1. A background display device for a virtual image recording studio that is configured to display, behind a real subject, a representation of a virtual background for a camera recording,wherein the background display device comprises at least one panel having a plurality of actively illuminating picture elements that form a two-dimensional arrangement that extends along a first direction of extent and a second direction of extent oriented perpendicular thereto, wherein a respective spacing, measured along the second direction of extent, of the picture elements from a first reference line that extends rectilinearly along the first direction of extent varies irregularly along the first direction of extent, wherein the panel has a number of separate picture element units that corresponds to the plurality of picture elements, said separate picture element units forming a regular arrangement, wherein each picture element unit has an eccentric light-emitting areal region that corresponds to a respective picture element, but that is eccentrically arranged with respect to a geometric center of the picture element unit, wherein the orientation of the respective eccentric light-emitting areal region varies along the regular arrangement of picture element units. 2. A background display device in accordance with claim 1 ,wherein the background display device is configured as an LED wall and the picture elements are configured as light-emitting diodes or light-emitting diode units. 3.
