Abstract
Described herein are ambient lighting devices, methods, and systems that utilize at least one multimode artificial ambient light source, a control unit, and a remote image sensor. The control unit couples to at least one artificial ambient light source and is configured to output at least one control signal to the at least one artificial ambient light source. The at least one multimode artificial ambient light source is configured to output light of varying color and color temperature in response to said at least one control signal. The remote image sensor couples to the at least one control unit and is configured to detect at least one color and intensity characteristic and output an output signal to the at least one control unit, based on said color and intensity characteristic detected.
Claims19
A lighting system, comprising:
- at least one multimode artificial ambient light source;
- at least one control unit coupled to said at least one artificial ambient light source and configured to output at least one control signal to said at least one artificial ambient light source wherein said at least one multimode artificial ambient light source is configured to output light of varying color and color temperature in response to said at least one control signal;
- and
- one remote image sensor coupled to said at least one control unit, wherein the remote sensor is configured to detect at least one color and intensity characteristic and send an output signal to said at least one control unit, based on said color and intensity characteristic detected and the detection by the remote image sensor utilizes an examined region of an image wherein the examined region is smaller than the complete area of the image.
A lighting method, comprising:
- detecting at least one color and intensity characteristic and producing an output signal to at least one control unit based on said color and intensity characteristic with a remote image sensor wherein the remote image sensor utilizes a frame grabber to provide an image of a video to detect at least one color and intensity characteristic by the image remote sensor;
- outputting at least one control signal to at least one artificial ambient light source by said at least one control unit;
- and
- outputting light of varying color and color temperature by at least one multimode artificial ambient light source in response to said at least one control signal and wherein the remote image sensor utilizes only one pixel for said color and intensity characteristic.
A lighting system, comprising:
- at least one multimode artificial ambient light source;
- at least one control unit coupled to said at least one artificial ambient light source and configured to output at least one control signal to said at least one artificial ambient light source wherein said at least one multimode artificial ambient light source is configured to output light of varying color and color temperature in response to said at least one control signal;
- one remote image sensor coupled to said at least one control unit, wherein the remote sensor is configured to detect at least one color and intensity characteristic of an image in a video and output an output signal to said at least one control unit, based on said color and intensity characteristic detected by the remote image sensor utilizing a frame grabber to provide the image to detect at least one color and intensity characteristic;
- and
- a monitor wherein the video is displayed on the monitor.
