Image Processing Method and Apparatus
First Claim
1. An image processing method comprising:
- a) acquiring a main image of a scene;
b) determining one or more facial regions in said main image;
c) analysing said one or more facial regions to determine if any one of said facial regions includes a defect;
d) acquiring a sequence of relatively low resolution images nominally of said scene for a time period not including a time for acquiring said main image;
e) determining one or more sets of low resolution facial regions in said sequence of low resolution images;
f) analysing said sets of facial regions to determine if any facial regions of a set corresponding to a defective facial region of said main image include a defect;
g) combining defect free facial regions of said corresponding set to provide a high quality defect free facial region; and
h) correcting at least a portion of any defective facial regions of said main image with image information from a corresponding high quality defect free facial region.

Abstract
An image processing technique includes acquiring a main image of a scene and determining one or more facial regions in the main image. The facial regions are analysed to determine if any of the facial regions includes a defect. A sequence of relatively low resolution images nominally of the same scene is also acquired. One or more sets of low resolution facial regions in the sequence of low resolution images are determined and analysed for defects. Defect free facial regions of a set are combined to provide a high quality defect free facial region. At least a portion of any defective facial regions of the main image are corrected with image information from a corresponding high quality defect free facial region.

44. An apparatus for providing images with enhanced facial regions in digital images, including a processor and one or more processor-readable media for programming the processor to control the apparatus to perform an image processing method that comprises:
