Abstract
An image processing method is configured to denoise three-dimensional image data. The image processing method includes an image transform step of performing a frequency transform for the three-dimensional image data in the optical axis direction and of calculating three-dimensional transformed image data, an image modulation step of reducing an absolute value of the three-dimensional transformed image data in a specific frequency region and of calculating three-dimensional modulated image data, and an inverse image transform step of performing an inverse frequency transform corresponding to the frequency transform for the three-dimensional modulated image data in the optical axis direction and of calculating three-dimensional inversely transformed image data. The specific frequency region is a part of a predetermined.
