Abstract
An apparatus and method is disclosed for automatically editing a digital color image to remove discoloration of the image, known as a "red eye" effect, by parsing the discoloration into regions and re-coloring the area of the discoloration based on the attributes of the discoloration. The editing process according to the invention automatically creates a bitmap that is a correction image, which is composited with the source image or a copy of it and displayed as the source image with the red eye effect corrected.
Claims26
In a computer system, a method for automatically editing a color image to remove discoloration of the image caused by a red eye artifact, the method comprising the steps of:
- identifying attributes of the red eye artifact;
- defining regions of the red eye artifact based on the identified attributes;
- selecting a color for re-coloring each region of the red eye artifact based on predetermined criteria for each of the regions;
- and re-coloring each of the regions with the associated selected colors.
A computer system for correcting a discoloration in a digital image, the computer system comprising:
- a source image with a red eye artifact;
- a mask registered with the source image and dividing the red eye artifact into regions;
- a tool for coloring the mask, where the color for each region is at least in part selected based on attributes of the particular region of the mask in which the color is applied;
- and, a composite image combining the source image and the colored mask, which visually appears as the source image with the red eye artifact replaced with a natural-looking coloring in an area of the pupil of the eye.
In a computer for receiving and displaying a color image having a red eye artifact, an article of manufacture comprising a medium that is readable by the computer and that carries instructions for the computer to perform a process comprising the steps of:
- parsing the red eye artifact into regions;
- selecting a color for re-coloring the image in each of the regions of the red eye artifact based on attributes of the region;
- and re-coloring each of the regions with the associated selected color.
A computer system for correcting a discoloration in a digital image, the computer system comprising:
- a source image with a red eye artifact, a mask registered with the source image and dividing the red eye artifact into regions, wherein the regions include a highlight region within the red eye artifact in which the discoloration is the brightest, and wherein the color of the highlight region includes a linear gradient of brightness of the color;
- a tool for coloring the mask, where the color is at least in part determined by the region of the mask in which the color is applied;
- and, a composite image combining the source image and the colored mask, which visually appears as the source image with the red eye artifact replaced with a natural-looking coloring in an area of the pupil of the eye.
