Abstract
A background display device for a virtual image recording studio is configured to display, behind a real subject, a representation of a virtual background for a recording by an associated camera and has at least one panel, which has a plurality of actively illuminating picture elements in a two-dimensional arrangement, and a control circuit. The control circuit is configured to control the picture elements to alternately display at least a part of the representation of the virtual background and a reference image that does not represent the virtual background, wherein the control circuit has a reference image memory in which the reference image can be stored.

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 recording by an associated camera,
- wherein the background display device has at least one panel, which has a plurality of actively illuminating picture elements in an at least two-dimensional arrangement, and a control circuit,
- wherein the control circuit is configured to control the picture elements to alternately display at least a part of the representation of the virtual background and a reference image that does not represent the virtual background,
- wherein the control circuit has a reference image memory in which the reference image can be stored,
- wherein the control circuit is configured, for the display of a transition from a first representation of the virtual background to a second representation of the virtual background, to control the picture elements to display the first representation in a first display window and to control the picture elements to display the second representation in a subsequent second display window, and
- wherein the control circuit is configured to control the picture elements during the first display window to display the first representation for a representation duration and to display the reference image for an image display duration, wherein the representation duration is greater than the image display duration or corresponds to the image display duration.
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 recording by an associated camera,
- wherein the background display device has at least one panel, which has a plurality of actively illuminating picture elements in a two-dimensional arrangement, an image content control device and a control circuit,
- wherein the image content control device is configured to generate the virtual background, to determine a projection of the virtual background onto the two-dimensional arrangement of the picture elements and to transmit the determined projection to the control circuit,
- wherein the control circuit is configured to control the picture elements to alternately display at least a part of the representation of the virtual background and a reference image that does not represent the virtual background,
- wherein the control circuit has a data input via which the reference image can be transmitted to the control circuit while bypassing the image content control device.
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 recording by an associated camera,
- wherein the background display device has at least one panel, which has a plurality of actively illuminating picture elements in an at least two-dimensional arrangement, and a control circuit,
- wherein the control circuit is configured to control the picture elements to alternately display at least a part of the representation of the virtual background and a reference image that does not represent the virtual background,
- wherein the control circuit has a reference image memory in which the reference image can be stored,
- wherein the control circuit is configured, for the display of a transition from a first representation of the virtual background to a second representation of the virtual background, to control the picture elements to display the first representation in a first display window and to control the picture elements to display the second representation in a subsequent second display window, and
- wherein the background display device has an interface for receiving information about an exposure window of the associated camera, wherein the control circuit is configured to control the picture elements outside the exposure window of the associated camera to display the reference image.
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 recording by an associated camera,
- wherein the background display device has at least one panel, which has a plurality of actively illuminating picture elements in an at least two-dimensional arrangement, and a control circuit,
- wherein the control circuit is configured to control the picture elements to alternately display at least a part of the representation of the virtual background and a reference image that does not represent the virtual background,
- wherein the control circuit has a reference image memory in which the reference image can be stored,
- wherein the background display device has an image content control device, wherein the image content control device is configured to generate the virtual background, to determine a projection of the virtual background onto the two-dimensional arrangement of the picture elements and to transmit the determined projection to the control circuit, and
- wherein the image content control device is configured to write changing representations of the virtual background into a background image memory connected to the control circuit.
A recording system comprising:
- background display device for a virtual image recording studio;
- and
- a camera,
- wherein the background display device is configured to display, behind a real subject, a representation of a virtual background for a recording by the camera,
- wherein the background display device has at least one panel, which has a plurality of actively illuminating picture elements in an at least two-dimensional arrangement, and a control circuit,
- wherein the control circuit is configured to control the picture elements to alternately display at least a part of the representation of the virtual background and a reference image that does not represent the virtual background,
- wherein the control circuit has a reference image memory in which the reference image can be stored,
- wherein the control circuit of the background display device is configured to receive a control command for displaying the reference image via an interface of the background display device and to control the picture elements to display the reference image in response to the control command, and
- wherein the camera is configured to transmit the control command to the interface of the background display device in dependence on an exposure pause of the camera.
