Abstract

The present invention relates to a method for providing an ambience light effect in a cinema comprising a cinema display screen arranged on a front wall of the cinema and a plurality of light sources, comprising receiving first and second image content to be sequentially displayed on the cinema display screen, determining at least one of a color and intensity for the second image content, determining a second set of control data for controlling the plurality of light sources to emit an ambient light effect based on at least one of the color and intensity for the second image content, and associating the second set of control data with the first set of image content. Advantages with the invention include the possibility to provide an improved ambient lighting experience by using the “extra space” specifically available in a cinema, e.g. walls, floor and ceiling.

Claims

1. A method for providing an ambience light effect in a cinema comprising a cinema display screen arranged on a front wall of the cinema and a plurality of light sources, comprising:

receiving first and second image content to be sequentially displayed on the cinema display screen;

determining at least one of a color and intensity for the second image content;

determining a second set of control data for controlling the plurality of light sources to emit an ambient light effect based on at least one of the color and intensity for the second image content; and

associating the second set of control data with the first set of image content.

2. Method according to claim 1, further comprising:

displaying the first image content on the cinema display screen; and

controlling the plurality of light sources to emit the ambience light effect using the second set of control data, wherein the first image content is displayed simultaneously with the plurality of light sources emitting the ambience light effect corresponding to the second set of control data.

3. Method according to claim 1, wherein the first image content is displayed on the cinema display device before the second image content.

4. Method according to claim 1, wherein the second image content is displayed on the cinema display device before the first image content.

5. An ambience lighting system for a cinema display screen arranged on a front wall of a cinema, comprising:

a control unit;

a plurality of light sources being connected to the control unit and configured to emit an ambience light effect;

wherein the plurality of light sources are at least one of;

arranged spaced apart on side walls of the cinema;

provided as a light emitting textile covering at least one of seats, a wall, a floor, and a ceiling of the cinema;

or

provided as a light emitting plaster covering at least one of a wall, a floor, and a ceiling of the cinema.

6. Ambient lighting system according to claim 5, wherein the control unit is configured to:

receive first and second image content to be sequentially displayed on the cinema display screen;

determine at least one of a color and intensity for the second image content;

determine a second set of control data for controlling the plurality of light sources to emit an ambient light effect based on at least one of the color and intensity for the second image content; and

controlling the plurality of light sources to emit the ambience light effect using the second set of control data simultaneously with the first image content being displayed on the cinema display screen.

7. Ambient lighting system according to claim 5, wherein the plurality of light sources comprises wall-washers.

8. A cinema, comprising a cinema display screen and an ambience lighting system according to claim 5.
