IMAGE ENHANCEMENT DEVICE FOR REDUCTION OF NOISE IN DIGITAL IMAGES
First Claim
1. An image enhancement device, comprising:
- a digital image recording device configured to register a series of subsequent images of a particular object, whereby each image comprises a matrix of pixels, each pixel representing a particular image content;
a processing unit configured to execute one or more de-noising operations to reduce induced noise in said series of subsequent images; and
a screen for visualising one or more registered images, wherein,the noise is reduced by identifying at least one pixel of noise in an image, removing the image content of said at least one pixel from the image and substituting said removed image content with replacement image content derived by overlapping the images of the series of subsequent images,whereby noise is defined as a physical obstruction or transient distortion between the object and the image recording device, andwhereby the processing unit is configured to execute one or more other de-noising operations before or after one or more images are visualised on the screen, and whereby one de-noising operation is selected from an averaging method.

Abstract
The invention relates to an image enhancement device comprising an image recording device, configured to register a series of subsequent images of a particular object, whereby each image includes a matrix of pixels, each pixel representing a particular image content, a processing unit configured to execute de-noising operations to reduce noise in said series of subsequent images, and a screen. The noise is reduced by identifying at least one pixel of noise in an image, removing the image content of said pixel from the image and substituting said removed image content with replacement image content derived by overlapping the images of the series of subsequent images. Further, the processing unit is configured to overlap images by integrating replacement image content from a second image into a first image from which the image content has been removed.

13. A method for reducing noise in a series if images registered using an image enhancement device comprising:
-
a digital image recording device configured to register a series of subsequent images of a particular object, whereby each image comprises a matrix of pixels, each pixel representing a particular image content; a processing unit configured to execute one or more de-noising operations to reduce induced noise in said series of subsequent images; a screen for visualising one or more registered images; reducing the noise by identifying at least one pixel of noise in an image; removing the image content of said at least one pixel from the image; and substituting said removed image content with replacement image content derived by overlapping the images of the series of subsequent images; and executing one or more other de-noising operations before or after one or more images are visualised on the screen, whereby one de-noising operation is selected from an averaging method using the processing unit; whereby noise is defined as a physical obstruction or transient distortion between the object and the image recording device. - View Dependent Claims (14, 15, 16)
