NOISE REDUCTION SYSTEM, NOISE REDUCTION PROGRAM, AND IMAGING SYSTEM

摘要

PROBLEM TO BE SOLVED: To obtain a high definition video signal by suppressing uneven appearance of noise due to signal processing.

SOLUTION: The noise reduction system which performs noise reduction processing to video signals fetched from an imaging system in a chronological order has: a noise reduction part 112 which performs the noise reduction processing to the video signals: a signal processing part 114 which performs a predetermined signal processing to the video signals to which the noise reduction processing has been performed; and a change amount calculation part 116 which calculates an amount of change of the video signal resulting from the signal processing, wherein the noise reduction part 112 controls the noise reduction processing based on the amount of change regarding the video signals in the past in chronological order.
