Abstract

An approach is provided that uses an array of LEDs to illuminate for digital image capturing. A system that includes a processor, a memory accessible by the processor, a digital camera accessible by the processor, a display screen accessible by the processor, and an array of a plurality of LEDs surrounding the display screen, where the array of LEDs is also accessible by the processor. Preferred image quality attributes are retrieved. Then a setting of a set of LEDs is made to a lighting attribute, such as color or brightness. Afterwards, the an image of a subject illuminated by the plurality of LEDs is captured and attributes of this image are compared to the preferred image quality attributes. Based on the comparison, the approach then adjusts the attributes of the set of LEDs.

First claim

What is claimed is:

1. A method, implemented by an information handling system comprising a processor, a memory accessible by the processor, a digital camera accessible by the processor, a display screen accessible by the processor, and a plurality of sets of light emitting diodes (LEDs) surrounding the display screen, each of the sets having one or more LEDs, wherein the plurality of sets of LEDs is accessible by the processor, the method comprising:
retrieving a set of one or more preferred image quality attributes;
setting each of the plurality of sets of LEDs with one or more lighting attributes, wherein each set of LEDs emit light according to its corresponding lighting attribute;
after the setting of each of the lighting attributes of each of the sets of LEDs, capturing, via the digital camera, one or more images of a subject illuminated by the plurality of LEDs;
comparing one or more image qualities of the captured one or more images to the preferred image quality attributes; and
adjusting at least one of the settings of at least one of the sets of LEDs based on the comparison, wherein at least a selected one of the lighting attributes of one of the sets of LEDs is different from the same selected lighting attribute of a different one of the sets of LEDs.

2. The method of claim 1 wherein at least one of the lighting attributes is selected from the group consisting of a lighting brightness and a lighting color.

3. The method of claim 1 further comprising:
adjusting a lighting brightness of the selected set of LEDs.

4. The method of claim 1 further comprising:
adjusting a lighting color of the selected set of LEDs.

5. The method of claim 4 wherein the lighting color is a color temperature ranging from a cool color to a warm color.

6. The method of claim 4 wherein the lighting color is a colored light.

7. An information handling system comprising:
one or more processors;
a memory coupled to at least one of the processors;
a digital camera accessible by at least one of the processors;
a display screen accessible by at least one of the processors;
a plurality of sets of light emitting diodes (LEDs) surrounding the display screen, each of the sets having one or more LEDs, wherein the plurality of sets of LEDs is accessible by at least one of the processors;
a set of computer program instructions stored in the memory and executed by at least one of the processors in order to perform actions comprising:
retrieving a set of one or more preferred image quality attributes;
setting each of the plurality of sets of LEDs with one or more lighting attributes, wherein each set of LEDs emit light according to its corresponding lighting attribute;
after the setting of each of the lighting attributes of each of the sets of LEDs, capturing, via the digital camera, one or more images of a subject illuminated by the plurality of LEDs;
comparing one or more image qualities of the captured one or more images to the preferred image quality attributes; and
adjusting at least one of the settings of at least one of the sets of LEDs based on the comparison, wherein at least a selected one of the lighting attributes of one of the sets of LEDs is different from the same selected lighting attribute of a different one of the sets of LEDs.

8. The information handling system of claim 7 wherein at least one of the lighting attributes is selected from the group consisting of a lighting brightness and a lighting color.

9. The information handling system of claim 7 wherein the actions further comprise:
adjusting a lighting brightness of the selected set of LEDs.

10. The information handling system of claim 7 wherein the actions further comprise:
adjusting a lighting color of the selected set of LEDs.

11. The information handling system of claim 10 wherein the lighting color is a color temperature ranging from a cool color to a warm color.

12. The information handling system of claim 10 wherein the lighting color is a colored light.

13. A computer program product comprising:
a non-transitory computer readable storage medium, comprising computer program code that, when executed by an information handling system, executes actions comprising:
retrieving a set of one or more preferred image quality attributes;
setting each of a plurality of sets of LEDs with one or more lighting attributes, wherein each set of LEDs emit light according to its corresponding lighting attribute;
after the setting of each of the lighting attributes of each of the sets of LEDs, capturing, via a digital camera, one or more images of a subject illuminated by the plurality of LEDs;
comparing one or more image qualities of the captured one or more images to the preferred image quality attributes; and
adjusting at least one of the settings of at least one of the sets of LEDs, based on the comparison, wherein
at least a selected one of the lighting attributes of one of the sets of LEDs is different from the same selected lighting attribute of a different one of the sets of LEDs.

14. The computer program product of claim 13 wherein at least one of the lighting attributes is selected from the group consisting of a lighting brightness and a lighting color.

15. The computer program product of claim 13 wherein the actions further comprise:
adjusting a lighting brightness of the selected set of LEDs.

16. The computer program product of claim 13 wherein the actions further comprise:
adjusting a lighting color of the selected set of LEDs.

17. The computer program product of claim 16 wherein the lighting color is a color temperature ranging from a cool color to a warm color.
