1. A medical system, comprising:
a light source configured to irradiate an imaging target with light;
an imaging device configured to capture a plurality of images based on reflected light from the imaging target; and
a central processing unit (CPU) configured to:
acquire the plurality of images from the imaging device, wherein the acquired plurality of images includes an image of interest and at least one even-numbered image;
determine that a frame number of the image of interest is an even number;
select, based on the determination that the frame number of the image of interest is the even number, a reference image from the at least one even-numbered image, wherein
the reference image is an image that is N frames before the image of interest, and
N is an integer that is one of equal to two or greater than two; and
perform a noise reduction process on the image of interest based on the reference image.
