Abstract

There is provided an electronic system including an image capturing device and a comparator coupled to the image capturing device. The image capturing device is operable for capturing a live image. The comparator generates a feedback signal by comparing the live image with a reference image and adjusts at least one setting of the image capturing device by the feedback signal.

Claims (28)

1. An electronic system comprising:

an image capturing device operable for capturing a first live image; and

a comparator coupled to said image capturing device and operable for generating a feedback signal by comparing said first live image with a reference image and for adjusting at least one setting of said image capturing device by said feedback signal, wherein said comparator is configured to determine a first matching percentage by comparing said first live image with said reference image, wherein said image capturing device is configured to capture a second live image after said at least one setting of said image capturing device is adjusted, and wherein said comparator is configured to determine a second matching percentage by comparing said second live image with said reference image.

2. The electronic system of claim 1 , wherein said at least one of said image capturing device comprises an image brightness setting.

3. The electronic system of claim 1 , wherein said at least one of said image capturing device comprises an image contrast setting.

4. The electronic system of claim 1 , wherein said comparator determines a direction of adjustment of said at least one setting of said image capturing device based on said first matching percentage and second matching percentage.

5. The electronic system of claim 1 , wherein said electronic system comprises a facial recognition system.

6. The electronic system of claim 1 , wherein said electronic system comprises a video conference system.

7. A computer system, comprising:

an image capturing device operable for capturing a first live image;

a storage system coupled to said image capturing device and operable for storing a sequence of machine-readable instructions; and

a processor coupled to said storage system and operable for executing said sequence of machine-readable instructions and for generating a feedback signal by comparing said first live image with a reference image, and for adjusting at least one setting of said image capturing device by said feedback signal, wherein said processor is configured to determine a first matching percentage by comparing said first live image with said reference setting, wherein said image capturing device is configured to capture a second live image after said at least one setting of said image capturing device is adjusted, and wherein said processor is configured to determine a second matching percentage by comparing said second live image with said reference image.

8. The computer system of claim 7 , wherein said at least one setting of said image capturing device comprises an image brightness setting.

9. The computer system of claim 7 , wherein said at least one setting of said image capturing device comprises an image contrast setting.

10. The computer system of claim 7 , wherein said processor determines a direction of adjustment of said at least one setting of said image capturing device based on said first matching percentage and said second matching percentage.

11. A method for optimizing at least one setting of an image capturing device, comprising:

capturing a first live image by said image capturing device;

generating a feedback signal by comparing said first live image with a reference image;

adjusting said at least one setting of said image capturing device according to said feedback signal;

determining a first matching percentage by comparing said first live image with said reference image;

capturing a second live image after said at least one setting of said image capturing device is adjusted; and

determining a second matching percentage by comparing said second live image with said reference image.

12. The method of claim 11 , wherein adjusting said at least one setting of said image capturing device with said feedback signal comprises:

adjusting an image brightness setting of said image capturing device.

13. The method of claim 11 , wherein adjusting said at least one setting of said image capturing device with said feedback signal comprises:

adjusting an image contrast setting of said image capturing device.

14. The method of claim 11 , further comprising:

determining a direction of adjustment of said at least one setting of said image capturing device based on said first matching percentage and second matching percentage.
