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 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.
