Image Blurring
First Claim
Patent Images
1. :
- A digital image processing device operable to blur an acquired image, comprising a controller and one or more processor readable storage devices having processor readable code embodied thereon, said processor readable code for programming one or more processors to perform a method of creating blur in a digital image, the method comprising;
(a) acquiring a first image of a scene taken at a first exposure level;
(b) acquiring a second image of nominally the same scene taken at a second exposure level, wherein at least one region of said second image includes one or more pixels having saturated intensity values;
(c) for at least one of said saturated pixels, extrapolating one or more values from said first image;
(d) generating a third image comprising pixels of said second image having non-saturated values, and pixels having said one or more extrapolated values;
(e) blurring at least a portion of the third image; and
(f) re-scaling the blurred portion of the third image.

Abstract
A method of blurring an image includes acquiring two images of nominally a same scene taken at a different light exposure levels. At least one region of one of the images includes pixels having saturated intensity values. For at least one of the saturated pixels, values are extrapolated from the other image. At least a portion of a third image is blurred and re-scaled including pixels having the extrapolated values.

- A digital image processing device operable to blur an acquired image, comprising a controller and one or more processor readable storage devices having processor readable code embodied thereon, said processor readable code for programming one or more processors to perform a method of generating a digital image, the method comprising;
(a) acquiring at least two images, including a full resolution image having one or more pixels with a saturated intensity value; (b) determining one or more intensity ratios from unsaturated pixels of another of the at least two acquired images; (c) modifying the full resolution image including restoring the one or more intensity ratios determined from the unsaturated pixels of said other acquired image; (d) blurring a portion of the modified image; and (e) printing, image processing, or electronically storing, transmitting or displaying the modified image, or combinations thereof. - View Dependent Claims (12, 13, 14, 15, 16)
