Abstract
A background display system for a virtual image recording studio comprises a background display device which is configured to display, behind or above a real subject, a representation of a virtual background for a recording by means of an associated camera, and a control device which is configured to control the background display device. The control device comprises a data input for receiving lens data from the associated camera and is configured to adjust the representation of the virtual background in dependence of the received lens data.
Claims28
A background display system for a virtual image recording studio comprising:
- a background display device which is configured to display, behind or above a real subject, a representation of a virtual background for a recording by an associated camera, and
- a control device which is configured to control the background display device,
- wherein the control device comprises a data input for receiving lens data of the associated camera, and wherein the control device is configured to adjust the representation of the virtual background in dependence of the received lens data,
- wherein the control device is connected to a memory in which the virtual background is stored as a model of sharp representation of the virtual background, the model of sharp representation having a first degree of blurring;
- and
- wherein the control device is configured to increase a degree of blurring of the representation of the virtual background towards a second degree of blurring that is higher than the first degree of blurring if the received lens data indicates an increase of a set value of a diaphragm aperture of a camera lens of the associated camera that corresponds to an increased opening of the diaphragm aperture.
A method for controlling a background display device which is configured to display a representation of a virtual background behind or above a real subject for a recording by means of an associated camera, including the steps:
- receiving lens data from the associated camera;
- generating the representation of the virtual background based on a stored model of sharp representation of the virtual background, the model of sharp representation having a first degree of blurring;
- adjusting the representation of the virtual background in dependence of the received lens data;
- and
- increasing a degree of blurring of the representation of the virtual background towards a second degree of blurring that is higher than the first degree of blurring if the received lens data indicates an increase of a set value of a diaphragm aperture of a camera lens of the associated camera that corresponds to an increased opening of the diaphragm aperture.
