Abstract

A method of creating a light script for a video is disclosed. The light script comprises lighting control instructions for controlling one or more light sources when the video is being displayed. The method ( 600 ) comprises: —receiving a user input indicative of a selection of a lighting control instruction for a scene (S 1 , S 11 , S 21 , S 31 , S 32 ), —associating the lighting control instruction (L 1 , L 11 , L 21 , L 31 , L 32 ) with the scene (S 1 , S 11 , S 21 , S 31 , S 32 ), —analyzing ( 602 ) the scene (S 1 , S 11 , S 21 , S 31 , S 32 ) of the video to identify a scene characteristic (C 1 , C 11 , C 21 , C 31 , C 32 ) in the scene, —analyzing ( 604 ) the video or another video to recognize, in a further scene (S 4 , S 13 , S 24 , S 34 ), a similar or identical scene characteristic (C 1 , C 11 , C 21 , C 31 , C 32 ), and—associating ( 606 ), based on the recognition of the similar or identical scene characteristic (C 1 , C 11 , C 21 , C 31 , C 32 ), the lighting control instruction (L 1 , L 11 , L 21 , L 31 , L 32 ) with the further scene (S 4 , S 13 , S 24 , S 34 ), such that when the scene (S 1 , S 11 , S 21 , S 31 , S 32 ) and the further scene (S 4 , S 13 , S 24 , S 34 ) are being displayed the one or more light sources are control led according to the lighting control instruction (L 1 , L 11 , L 21 , L 31 , L 32 ).

Claims (32)

1. A method of creating a light script for a video, the light script comprising lighting control instructions for controlling one or more light sources when the video is being displayed, the method comprising:

receiving a user input indicative of a selection of a lighting control instruction for a scene,

associating the lighting control instruction with the scene,

analyzing the scene of the video to identify a scene characteristic in the scene,

analyzing the video or another video to recognize, in a further scene, a similar or identical scene characteristic, and

associating, based on the recognition of the similar or identical scene characteristic, the lighting control instruction with the further scene, such that when the scene and the further scene are being displayed the one or more light sources are controlled according to the lighting control instruction.

2. The method of claim 1 , further comprising:

extracting one or more colors from one or more images of the scene, and

generating the lighting control instruction based on the one or more colors.

3. The method of claim 1 , wherein the lighting control instruction comprises color information, position information and/or timing information for controlling the one or more light sources.

4. The method of claim 1 , wherein the method further comprises associating the lighting control instruction with one or more intermediary scenes of the video in between the scene and the further scene.

5. The method of claim 4 , wherein the step of associating the lighting control instruction with the one or more intermediary scenes is executed if a time period between the scene and the further scene is below a threshold time period.

6. The method of claim 4 , further comprising the steps of:

analyzing the scene, the further scene and the one or more intermediary scenes,

identifying a secondary scene characteristic, different from the scene characteristic, in each of the scene, the further scene and the one or more intermediary scenes,

wherein the step of associating the lighting control instruction with the one or more intermediary scenes is executed if the secondary scene characteristic has been identified in the scene, the further scene and the one or more intermediary scenes.

7. The method of claim 1 , wherein the step of analyzing the scene to identify the scene characteristic comprises identifying at least one object, shape, character and/or person in the scene, and wherein the step of analyzing the video or another video to recognize, in the further scene, the scene characteristic comprises recognizing the at least one recognized one object, shape, character and/or person in the further scene.

8. The method of claim 1 , wherein the step of analyzing the scene to identify the scene characteristic comprises identifying at least one audio fragment in the scene, and wherein the step of analyzing the video or another video to recognize, in the further scene, the scene characteristic comprises recognizing the at least one recognized audio fragment in the further scene.

9. The method of claim 1 , wherein the step of analyzing the scene to identify the scene characteristic in the scene comprises identifying a plurality of scene characteristics in the scene, and wherein the method further comprises:

communicating the plurality of scene characteristics to a user via a user interface,

receiving one or more user inputs representative of a selection of one or more of the plurality of scene characteristics,

and wherein the analysis of the video or another video comprises recognizing, in the further scene, the one or more selected scene characteristics.

10. The method of claim 1 , wherein the method further comprises:

obtaining a first weight value for a first scene characteristic in a first scene associated with a first lighting control instruction,

obtaining a second weight value for a second scene characteristic in a second scene associated with a second lighting control instruction, and

associating, if the first and second scene characteristics are recognized in the further scene, the first or the second lighting control instruction with the further scene based on the first and second weight values.

11. The method of claim 1 , further comprising, before associating the lighting control instruction with the further scene, receiving a user input indicative of an acceptance of the association between the lighting control instruction and the further scene.

12. The method of claim 1 , further comprising storing the light script as a computer readable file, or embedding the light script in a video file of the video.

13. A computer program product for a computing device, the computer program product comprising computer program code to perform the method of claim 1 when the computer program product is run on a processing unit of the computing device.

14. A system for creating a light script for a video, the light script comprising lighting control instructions for controlling one or more light sources when the video is being displayed, the system comprising:

a user interface configured to receive a user input indicative of a selection of a lighting control instruction for a scene, and

a processor configured to associate the lighting control instruction with the scene, analyze the scene, to identify a scene characteristic in the scene, analyze the video or another video to identify, in a further scene, a similar or identical scene characteristic, and to associate, based on the recognition of the similar or identical scene characteristic, the lighting control instruction with the further scene, such that when the scene and the further scene are being displayed the one or more light sources are controlled according to the lighting control instruction.
