Abstract

An illuminating control system for controlling a plurality of illuminating devices is disclosed herein. The illuminating control system includes an image capturing device and a processor. The image capturing device is configured to capture images of an object. The processor is coupled to the image capturing device. The processor is configured to receive the images and determine whether the object is a predetermined object based on the images. If the processor determines that the object is the predetermined object, the processor controls the image capturing device to track the object to obtain a moving condition of the object. The processor turns on one of the illuminating devices correspondingly based on the moving condition of the object.

Claims

1. A method for controlling an illuminating device comprising:

receiving an image of an object;

determining whether the object is a predetermined object based on the image;

tracking the object to obtain a moving condition of the object if the object is determined to be the predetermined object; and

turning on one of a plurality of illuminating devices correspondingly based on the moving condition of the object.

2. The method for controlling the illuminating device of claim 1, wherein the step of turning on the one of the plurality of illuminating devices correspondingly based on the moving condition of the object comprises:

predicting a first moving position of the object based on the moving condition to turn on a first illuminating device of the illuminating devices corresponding to the first moving position.

3. The method for controlling the illuminating device of claim 2, wherein the step of predicting the first moving position of the object based on the moving condition to turn on the first illuminating device of the illuminating devices corresponding to the first moving position comprises:

turning on the first illuminating device of the illuminating devices closest to the first moving position correspondingly based on the first moving position of the object which is predicted.

4. The method for controlling the illuminating device of claim 2, wherein the step of predicting the first moving position of the object based on the moving condition to turn on the first illuminating device of the illuminating devices corresponding to the first moving position comprises:

turning on the first illuminating device of the illuminating devices that illuminates light to the first moving position correspondingly based on the first moving position of the object which is predicted.

5. The method for controlling the illuminating device of claim 2, wherein the step of predicting the first moving position of the object based on the moving condition to turn on the first illuminating device of the illuminating devices corresponding to the first moving position comprises:

controlling the first illuminating device to illuminate a first brightness when the first moving position of the object is predicted; and

controlling the first illuminating device to illuminate a second brightness when the object reaches the first moving position, wherein the second brightness is greater than the first brightness.

6. The method for controlling the illuminating device of claim 2, further comprising:

predicting a second moving position of the object based on the moving condition;

controlling the first illuminating device to illuminate a first brightness when the object leaves the first moving position; and

controlling the first illuminating device to illuminate a second brightness or turn off the first illuminating device when the object reaches the second moving position, wherein the second brightness is smaller than the first brightness.

7. The method for controlling the illuminating device of claim 1, wherein the moving condition comprises one of a motion vector and a motion locus.

8. The method for controlling the illuminating device of claim 2, wherein the moving condition comprises one of a motion vector and a motion locus.

9. The method for controlling the illuminating device of claim 3, wherein the moving condition comprises one of a motion vector and a motion locus.

10. The method for controlling the illuminating device of claim 1, wherein the step of determining whether the object is the predetermined object based on the image comprises:

performing feature recognition or face detection of the image of the object to determine whether the object is the predetermined object.

11. The method for controlling the illuminating device of claim 2, wherein the step of determining whether the object is the predetermined object based on the image comprises:

performing feature recognition or face detection of the image of the object to determine whether the object is the predetermined object.

12. The method for controlling the illuminating device of claim 5, wherein a number of predetermined objects is plural, wherein the first brightness and the second brightness respectively correspond to one of the predetermined objects.

13. The method for controlling the illuminating device of claim 6, wherein a number of predetermined objects is plural, wherein the first brightness and the second brightness respectively correspond to one of the predetermined objects.

14. The method for controlling the illuminating device of claim 5, wherein the first brightness and the second brightness correspond to different time periods.

15. The method for controlling the illuminating device of claim 6, wherein the first brightness and the second brightness correspond to different time periods.

16. The method for controlling the illuminating device of claim 5, further comprising determining whether the first moving position or the second moving position is within a predetermined range, magnitudes of the first brightness and the second brightness corresponding to a determination result.

17. The method for controlling the illuminating device of claim 6, further comprising determining whether the first moving position or the second moving position is within a predetermined range, magnitudes of the first brightness and the second brightness corresponding to a determination result.

18. The method for controlling the illuminating device of claim 5, further comprising determining a time period for which the object stays at the first moving position or the second moving position, magnitudes of the first brightness and the second brightness being correspondingly adjusted when the time period reaches a predetermined value.

19. The method for controlling the illuminating device of claim 6, further comprising determining a time period for which the object stays at the first moving position or the second moving position, magnitudes of the first brightness and the second brightness being correspondingly adjusted when the time period reaches a predetermined value.

20. An illuminating control system for controlling a plurality of illuminating devices comprising:

an image capturing device configured to capture an image of an object; and

a processor coupled to the image capturing device configured to perform the method for controlling the illuminating device of claim 1.
