Title:
NOISE ELIMINATION DEVICE, NOISE ELIMINATION METHOD, AND NOISE ELIMINATION PROGRAM
Document Type and Number:
Japanese Patent JP2013126237
Kind Code:
A
Abstract:

To make it possible to detect and eliminate random noise with precision and prevent pixels, which should not originally be eliminated, from being erroneously detected as noise and eliminated.

A horizontal deviation detection part 152 detects a movement of a person 10, who is an imaging object, between adjacent frames. A horizontal position alignment part 153 performs alignment to align a previous frame with a current frame using the deviation detected by the horizontal deviation detection part 152. Then, a noise elimination part 154 obtains a difference in image between the aligned previous frame and the current frame stored in a frame memory 142, determines a part, which is extracted as the difference, as random noise, and performs noise elimination.
