Abstract
In a method of displaying a representation of a virtual background by means of a background display device for a recording by a camera in a virtual image recording studio, the display of the representation of the virtual background takes place in accordance with a time control. The camera further records the display of the representation of the virtual background in accordance with a sequence of exposure times and the time control of the display of the representation of the virtual background and the sequence of exposure times are synchronized with one another.
Claims20
A camera for a recording of a representation of a virtual background that is intermittently displayed in a virtual image recording studio on an associated background display device in accordance with a light pulse frequency,
- wherein the camera comprises an interface for receiving a value of the light pulse frequency of the associated background display device and a control device,
- wherein the control device is configured to control the camera in accordance with a settable exposure time, and
- wherein the control device is configured to determine a plurality of permitted exposure times in dependence on the received value of the light pulse frequency.
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 a control device that is configured to control the background display device to intermittently display the representation of the virtual background in accordance with a settable light pulse frequency,
- wherein the background display device has an interface that is configured to receive a value of a set exposure time of the associated camera, and
- wherein the control device is configured to set the light pulse frequency of the background display device in dependence on the received value of the set exposure time of the associated camera.
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 a control device that is configured to change the representation of the virtual background at settable refresh times,
- wherein the background display device has an interface that is configured to receive information about exposure pauses between consecutive exposures of the associated camera, and
- wherein the control device is configured to set the refresh times of the background display device in dependence on the received information about the exposure pauses of the associated camera.
A camera for a recording of a representation of a virtual background that is displayed in a virtual image recording studio on an associated background display device and that changes at refresh times,
- wherein the camera has an interface that is configured to receive information about the refresh times of the associated background display device,
- wherein the camera has a control device that is configured to control the camera in accordance with a settable exposure time, and
- wherein the control device is configured to set exposure pauses of the camera in dependence on the received information about the refresh times.
