Abstract
The examples relate to a method and apparatus to measuring ambient light information that is used in the manipulation or augmentation of an image presented on a display. The apparatus measures ambient light characteristic information from at least one direction in an environment in which the apparatus is located. The measured ambient light characteristic enable substantially real time generation and application of an image effect to an image presented on a display device.
Claims12
A lighting system, comprising:
- a light probe comprising:
- directional light intensity sensors configured to measure light intensity of ambient light received from more than one direction with respect to a center point of the light probe;
- and
- a color component sensor configured to measure color components of the ambient light;
- a lighting device comprising an image display device that presents an image and outputs general illumination;
- a communication interface coupled to an external source;
- and
- a processing system, in or in communication with the image display device, comprising:
- a memory;
- a processor coupled to the memory, the communication interface and the light probe, and coupled to control operation of the image display device;
- and
- programming in the memory, wherein execution of the programming by the processor configures the processing system to perform functions including functions to:
- receive configuration data from the external source, the configuration data includes a selected image of a luminaire and a general lighting distribution selection;
- obtain the selected image of the luminaire from the configuration data for output via the display device;
- obtain ambient light information measured by the light probe;
- modify the selected image by applying an image effect that is generated at least in response to the ambient light information;
- control operation of the image display device to present the modified image of the luminaire as the presented image;
- and
- generate a general lighting distribution for illumination based on the general lighting distribution selection.

A method, comprising:
- receiving configuration data from an external source, wherein the configuration data includes a selected image of a luminaire and a general lighting distribution selection;
- presenting on an image display device located in a premises, an image of luminaire based on the image selection in the configuration data;
- outputting from the image display device illumination light based on the general lighting distribution selection;
- measuring an intensity of the ambient light in the premises by a first sensor of a probe, the first sensor being positioned and oriented in a first direction with reference to a central axis of the probe;
- measuring an intensity of the ambient light in the premises by a second sensor of the probe positioned and oriented in a second direction with reference to the central axis of the probe;
- measuring an intensity of the ambient light in the premises by a third sensor of the probe positioned and oriented in a third direction with reference to the central axis of the probe, wherein the first, second and third directions are different from one another;
- measuring color components of the ambient light by a color component sensor of the probe;
- providing, in real time, ambient light intensity values based on the measurements by the first, second and third sensors and direction values indicating the direction from which the ambient light intensity value was measured;
- providing, in real time, color component values of the ambient color components based on the measurements by the color component sensor;
- generating, by a processor, an image effect utilizing the provided ambient light intensity values, direction values and color component values that accounts for the changes of ambient light in the premises;
- and
- applying the generated image effect to the image of the object presented on the image display device to provide a modified image, wherein the applied generated image effect alters an appearance of the image on the image display device based on changes to ambient light in the premises.
