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 camera recording and comprises an active illumination apparatus that comprises at least one panel having a plurality of picture elements in an at least two-dimensional arrangement; a control device; and a controllable lens arrangement. The control device is configured to control the active illumination apparatus to display the representation of the virtual background, and is configured to change a beam characteristic of at least some of the plurality of picture elements by controlling the lens arrangement.
Claims18
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, said background display device comprising
- an active illumination apparatus that comprises at least one panel having a plurality of picture elements in an at least two-dimensional arrangement;
- a control device;
- and
- a controllable lens arrangement,
- wherein the control device is configured to control the active illumination apparatus to display the representation of the virtual background,
- wherein the control device is configured to change a beam characteristic of at least some of the plurality of picture elements by controlling the lens arrangement,
- wherein the control device is configured to control the active illumination apparatus to change the displayed representation of the virtual background at an image refresh rate, and
- wherein the control device is configured to control the lens arrangement in accordance with the image refresh rate.
A method of displaying a representation of a virtual background by a background display device for a recording by a camera in a virtual image recording studio,
- wherein the background display device has an active illumination apparatus, which comprises at least one panel having a plurality of picture elements in an at least two-dimensional arrangement, and a lens arrangement that comprises a respective individually controllable lens for each picture element of the plurality of picture elements, comprising the steps:
- generating the representation of the virtual background;
- controlling the picture elements to display the representation of the virtual background;
- and
- controlling the lens arrangement to change a beam characteristic of the picture elements,
- wherein the displayed representation of the virtual background is changed at an image refresh rate, and wherein the lens arrangement is controlled in accordance with the image refresh rate.
