Abstract
The present invention relates to an interactive system (1) for controlling lighting and/or image playback, the system comprising: at least one image acquisition device, in particular a video camera (2); a base module (3) configured to receive and analyze information from the image acquisition device (2) in order to detect the presence of at least one person (P) in the field of the image acquisition device; and at least one control module (4) configured to receive a control signal coming from the base module (3) and, as a function of said control signal, to control the intensity and/or the orientation of at least one light source (5) and/or at least one played-back visual content, in order to comply with a predefined lighting relationship.
Claims25
An interactive system (1) for controlling lighting and/or image playback, the system comprising:
- at least one image acquisition device, in particular a video camera (2);
- a base module (3) configured to receive and analyze information from the image acquisition device (2) in order to detect the presence of at least one person (P) in the field of the image acquisition device;
- and
- at least one control module (4) configured to receive a control signal coming from the base module (3) and, as a function of said control signal, to control the intensity and/or the orientation of at least one light source (5) and/or at least one played-back visual content, in order to comply with a predefined lighting relationship;
- the base module (3) being configured, at least while the system is initially being put into service, to cause the light sources (5) to be switched on in succession and to record the spatial distribution of the light intensity produced by each of said light sources (5).
An interactive system (1) for controlling lighting and/or image playback, the system comprising:
- at least one image acquisition device, in particular a video camera (2);
- a base module (3) configured to receive and analyze information from the image acquisition device (2) in order to detect the presence of at least one person (P) in the field of the image acquisition device;
- and
- at least one control module (4) configured to receive a control signal coming from the base module (3) and, as a function of said control signal, to control the intensity and/or the orientation of at least one light source (5) and/or at least one played-back visual content, in order to comply with a predefined lighting relationship;
- the image acquisition device, the base module, and one or more control modules being incorporated in a luminaire fitting, in particular a chandelier, and
- the luminaire fitting including a light source (5b) providing diffuse lighting and at least two light sources (5a) providing directional lighting, each associated with a respective control module (4).
A system according to any preceding claim, including at least one remote control module (4) communicating with the base module (3) by power line carrier.
A system according to any preceding claim, the image acquisition device (2) comprising a video camera having 360° vision.
A system according to any preceding claim, including a pyroelectric sensor.
A method of automatically modifying the lighting of a space (7) including at least one light source (5a) providing directional lighting and at least one light source (5b) providing diffuse lighting for lighting the space at least in part, the method comprising the steps consisting in:
- acquiring at least one image of at least a portion of said space (7) suitable for being lighted at least by said light source (5);
- analyzing said image to detect the presence of at least one person;
- and
- as a function of the analysis as performed in this way, controlling the light source(s) (5) so as to comply with a predefined lighting relationship for said space governing the ratio between the level of lighting from the light source(s) (5a) providing directional lighting and the lighting provided by the light sources (5b) providing diffuse lighting.
A method according to the preceding claim, including the step consisting in analyzing said image to measure the light level of at least said portion of the space.
An interactive system (100) for lighting an object (O), the interactive system comprising:
- one or more light sources (101) lighting the object (O);
- a camera (102) having its field of view directed in a direction away from the object (O);
- and
- a data processor system (103) for processing the data coming from the camera (102) and for controlling the light source(s) (101);
- the processor system (103) being arranged to modify the lighting delivered by the light source(s) (101) as a function of detecting at least a portion of the face of a person (P) in the field of observation of the camera (102).
A method of automatically modifying the lighting of an object (O) lighted by at least one light source (101), in particular an object in a shop window, a showcase, or a museum, the method comprising the following steps:
- acquiring an image by means of a camera (102) having its field of view directed in a direction away from the object (O);
- detecting in the acquired image at least a portion of the face of a person (P);
- and
- modifying the lighting of the source(s) (101) as a function of the detection performed in the preceding step.
