Abstract

A lighting control device which controls a lighting device, and includes: a feature quantity calculator which calculates a feature quantity of image content to be reproduced and projected by an image reproducing device; and a lighting controller which controls light emission of the lighting device based on the feature quantity calculated by the feature quantity calculator.

First claim

What is claimed is:

1 . A lighting control device which controls a lighting device, the lighting control device comprising:
a calculator which calculates a feature quantity of image content to be reproduced and projected by an image reproducing device; and a lighting controller which controls light emission of the lighting device based on the feature quantity calculated by the calculator.

2 . The lighting control device according to claim 1 ,
wherein the lighting controller includes an auxiliary information outputter which generates auxiliary information using the feature quantity calculated by the calculator and outputs the auxiliary information, the auxiliary information being for assisting determination of a value based upon which the lighting controller controls the light emission of the lighting device.

3 . The lighting control device according to claim 2 ,
wherein the auxiliary information outputter generates and outputs the auxiliary information suitable for display on a settings screen from which the lighting controller is configured to receive, as an input, the value based upon which the lighting controller controls the light emission of the lighting device.

4 . The lighting control device according to claim 2 ,
wherein the auxiliary information outputter generates and outputs the auxiliary information including information indicating at least one of a recommended value and a recommended range for the value based upon which the lighting controller controls the light emission of the lighting device, the at least one of a recommended value and a recommended range being determined according to the feature quantity.

5 . The lighting control device according to claim 2 ,
wherein the lighting controller controls the light emission of the lighting device based on a setting value that is a value input to the lighting controller in accordance with the auxiliary information.

6 . The lighting control device according to claim 1 ,
wherein the calculator selects at least one frame from among a plurality of frames included in the image content that is a moving image, and calculates the feature quantity using the at least one frame.

7 . The lighting control device according to claim 1 , further comprising
an image controller configured to instruct the image reproducing device to reproduce the image content.

8 . The lighting control device according to claim 7 ,
wherein when the image content is a moving image, the image controller configured to instruct the image reproducing device to reproduce at least two frames selected from among a plurality of frames included in the image content.

9 . The lighting control device according to claim 1 ,
wherein the calculator obtains the image content and calculates the feature quantity based on the image content.

10 . The lighting control device according to claim 9 , further comprising
a communicator which communicates with the image reproducing device, wherein the calculator obtains the image content transmitted by the image reproducing device, via the communicator.

11 . A lighting system comprising
the lighting control device, the lighting device, and the image reproducing device according to claim 1 .

12 . A non-transitory computer-readable recording medium having a program stored thereon which, when executed by a computer, causes the computer to:
calculate a feature quantity of image content to be reproduced and projected by an image reproducing device; and control light emission of the lighting device based on the feature quantity calculated in the calculating.
