Lighting system and shooting system

Abstract

To provide a lighting system that can easily and appropriately irradiate a subject.SOLUTION: A lighting system includes an irradiation device that irradiates, with light, a subject located in front of a display unit displaying a background image, an information acquisition device that acquires subject information for identifying the subject, a storage unit that stores background image information about the background image displayed on the display unit, and a control unit that controls irradiation by the irradiation device. The control unit generates shape information of the subject based on a difference between the subject information acquired by the information acquisition device and the background image information stored in the storage unit, and sets an irradiation range irradiated with light by the irradiation device based on the shape information.SELECTED DRAWING: Figure 3

Claims

1. An illumination device that shines light onto a subject located in front of the display unit that displays the background image, An information acquisition device that acquires subject information for identifying the aforementioned subject, A storage unit that stores background image information relating to the background image displayed on the display unit, The system comprises a control unit that controls irradiation by the aforementioned irradiation device, The control unit, Based on the difference between the subject information acquired by the information acquisition device and the background image information stored in the storage unit, shape information of the subject is generated. Based on the shape information, the irradiation range is set so that only the subject is irradiated with light by the irradiation device. The illumination device is a lighting system that illuminates only the illumination range set by the control unit, without illuminating the background image displayed on the display unit.

2. The information acquisition device includes a distance measuring device that acquires distance information indicating the distance to the subject as subject information, The storage unit stores information indicating the distance to the display unit on which the background image is displayed as background image information. The lighting system according to claim 1, wherein the control unit generates the shape information of the subject based on the difference between the distance information measured by the distance measuring device and the background image information.

3. The information acquisition device includes an imaging device that acquires an image containing at least the subject as subject information. The storage unit stores, as background image information, image data for displaying the background image on the display unit. The lighting system according to claim 1, wherein the control unit generates the shape information of the subject based on the difference between the captured image acquired by the imaging device and the background image information.

4. The lighting system according to any one of claims 1 to 3, wherein the control unit determines whether or not the subject has moved, and if it determines that the subject has moved, updates the setting of the illumination range.

5. The illumination system according to any one of claims 1 to 3, wherein the illumination device is a projector.

6. The illumination system according to any one of claims 1 to 3, wherein the illumination device provides light and dark areas within the range of the subject.

7. The illumination system according to any one of claims 1 to 3, wherein the irradiation device irradiates light such that the set irradiation range becomes brighter than other ranges.

8. The lighting system according to any one of claims 1 to 3, wherein the control unit acquires information regarding the brightness and color temperature of the background image, generates adjustment information for adjusting the brightness and color of the light illuminating the subject with the illumination device, and controls the illumination of the illumination range by the illumination device based on the adjustment information.

9. The lighting system according to any one of claims 1 to 3, wherein the control unit determines whether the position of the light source illuminating the background image has changed, and if it determines that the position of the light source has changed, it obtains light source position information indicating the position of the light source after the change, generates brightness adjustment information for adjusting the distribution of brightness and darkness in the illumination range based on the light source position information, and controls the illumination of the illumination range by the illumination device based on the brightness adjustment information.

10. The lighting system according to claim 1, A display device having the aforementioned display unit, A shooting system comprising a shooting device that captures the subject and the background image displayed on the display unit together.
