Captured image evaluation apparatus, captured image evaluation method, and captured image evaluation program

A captured image evaluation method comprising:

• acquiring a plurality of captured images obtained by imaging a subject under conditions in which a numerical aperture of an objective lens is different;
• estimating a thickness of the subject on the basis of a low NA captured image obtained under a condition in which the numerical aperture of the objective lens is relatively small, among the plurality of captured images;
• and
• estimating a density of the subject on the basis of a high NA captured image obtained under a condition in which the numerical aperture of the objective lens is relatively large, among the plurality of captured images.

A non-transitory computer recording medium storing a captured image evaluation program that causes a computer to function as:

• an image acquisition section that acquires a plurality of captured images obtained by imaging a subject under conditions in which a numerical aperture of an objective lens is different;
• a thickness estimation section that estimates a thickness of the subject on the basis of a low NA captured image obtained under a condition in which the numerical aperture of the objective lens is relatively small, among the plurality of captured images;
• and
• a density estimation section that estimates a density of the subject on the basis of a high NA captured image obtained under a condition in which the numerical aperture of the objective lens is relatively large, among the plurality of captured images.
