Abstract

A method that includes receiving an image, automatically determining at least one region of interest in the image based on at least one color deficiency type from a plurality of color deficiency types, modifying the image by correcting the at least one region of interest and producing an output of the modified image.

Claims (44)

1. A method, comprising:

receiving an image;

automatically determining at least one region of interest in the image based on at least one color deficiency type from a plurality of color deficiency types;

modifying the image by correcting the at least one region of interest; and

producing an output of the modified image,

wherein the correcting the at least one region of interest is performed when the at least one region of interest reaches a predetermined size and wherein at least one of the receiving, the automatically determining, the modifying and the producing is performed by a processor.

2. The method of claim 1 , wherein the determining the at least one region of interest includes searching for a color in the image having a specified color space value in the image.

3. The method of claim 2 , further comprising assigning a common color space value to at least two colors in the image that appear similar based on the at least one color deficiency type.

4. A method, comprising:

receiving an image;

automatically determining at least one region of interest in the image based on at least one color deficiency type from a plurality of color deficiency types;

modifying the image by correcting the at least one region of interest; and

producing an output of the modified image,

wherein the determining the at least one region of interest includes checking a percentage of the determined at least one region of interest for each color deficiency type of the plurality of color deficiency types relative to a total size of the image and wherein at least one of the receiving, the automatically determining, the modifying and the producing is performed by a processor.

5. The method of claim 4 , wherein the correcting corrects the determined at least one region of interest for the color deficiency type with a highest percentage.

6. The method of claim 1 , wherein the correcting the determined at least one region of interest ends after a threshold percentage of the image has been modified.

7. The method of claim 1 , wherein the correcting the at least one region of interest includes remapping a color in the at least one region of interest to another color that is distinguishable from other colors in the at least one region of interest.

8. The method of claim 1 , wherein the correcting the at least one region of interest includes embedding a spatial texture in the determined at least of region of interest.

9. The method of claim 1 further comprising, receiving at least one region of concern in the image.

10. The method of claim 9 further comprising, checking the at least one region of concern for the at least one region of interest based on at least one type of color deficiency.

11. The method of claim 10 further comprising, correcting the region of concern when the region of concern contains at least two regions of interest have been determined.

12. An imaging device with a non-transitory computer-readable storage medium containing computer executable instructions to:

receive an image;

determine at least one region of interest in the image based on at least one color deficiency type;

modify the image by correcting the at least one region of interest; and

produce an output of the corrected image,

wherein the correcting the at least one region of interest is performed when the at least one region of interest reaches a predetermined size.

13. The imaging device of claim 12 , wherein the determining the at least one region of interest includes searching for a color in the image having a specified color space value in the image.

14. The imaging device of claim 12 , wherein the correcting the at least one region of interest is performed when at least two regions of interest have been determined.

15. The imaging device of claim 12 , wherein the at least one color deficiency type is selected from a plurality of color deficiency types stored in the non-transitory computer-readable storage medium of the imaging device.

16. A computer program product embodied on a non-transitory computer readable storage medium, the computer program product comprising a program module having instructions for:

receiving an image;

automatically determining at least one region of interest in the image based on at least one color deficiency type from a plurality of color deficiency types;

modifying the image by correcting the at least one region of interest; and

producing an output of the modified image,

wherein if the determined at least one region of interest reaches a predetermined size, detecting at least one more region of interest in an area bordering the determined at least one region of interest.

17. The computer program product of claim 16 , wherein the determining the at least one region of interest includes searching for a color in the image having a specified color space value in the image.

18. A method, comprising:

receiving an image;

automatically determining at least one region of interest in the image based on at least one color deficiency type from a plurality of color deficiency types;

detecting at least one more region of interest in an area bordering the determined at least one region of interest if the determined at least one region of interest reaches a predetermined size;

modifying the image by correcting the at least one region of interest; and

producing an output of the modified image,

wherein at least one of the receiving, the automatically determining, the modifying and the producing is performed by a processor.
