Method and apparatus for detection and correction of multiple image defects within digital images using preview or other reference images
First Claim
1. A portable image acquisition and processing device which automatically detects and corrects face region defects within digital images, comprising a processor, image sensor and lens to acquire digital images, and a memory having code embedded therein for programming the processor to perform a multiple image defect detection and correction method that comprises:
- using the processor, image sensor and lens to acquire and process a main digital image;
applying an analysis filter to one or more preview or other reference images of approximately a same scene as said main digital image;
interpreting results of the applying said analysis filter;
determining an optimal correction strategy for application to the main digital image based on the interpreting;
determining an optimal combination of corrective image processing and filter adaptation based on the strategy; and
correcting multiple image defects based on said applying said analysis filter in accordance with said optimal combination, including detecting and correcting one or more defects within a specific region of interest within said digital image.

Abstract
A method for red-eye detection in an acquired digital image acquiring one or more preview or other reference images without a flash. Any red regions that exist within the one or more reference images are determined. A main image is acquired with a flash of approximately a same scene as the one or more reference images. The main image is analyzed to determine any candidate red eye defect regions that exist within the main image. Any red regions determined to exist within the one or more reference images are compared with any candidate red eye defect regions determined to exist within the main image. Any candidate red eye defect regions within the main image corresponding to red regions determined also to exist within the one or more reference images are removed as candidate red eye defect regions.
