Abstract

A reflected light image and a fluorescent light image of an observed region are acquired with an imaging system. A gradation level of the reflected light image is set on the basis of a feature value of the acquired reflected light image. The focus of the imaging system is controlled in accordance with the set gradation level. The fluorescent light image is corrected using a focus-controlled reflected light image of the observed region. Accordingly, the image of an object in the observed region from which the fluorescent light is generated is sharpened.

First claim

What is claimed is:

1. An image processing device, comprising:
an image acquiring unit that acquires a reflected light image and a fluorescent light image of an observed region, the reflected and the fluorescent light images being captured by an imaging system;
a feature value calculating unit that calculates a feature value of the reflected light image acquired by the image acquiring unit;
an amount-of-shift-of-focus setting unit that sets an amount of shift of focus of the r…
