Abstract
The endoscope apparatus includes an image acquisition section (image composition processing section) that acquires a captured image in a zoom observation state in time series, the zoom observation state being an observation state in which a magnification of an optical system is higher than that in a normal observation state, a defocus amount information extraction section (texture extraction section) that extracts defocus amount information from the captured image in the zoom observation state, and a defocus amount correction section (texture correction amount calculation section, texture correction section, and blending section) that corrects the captured image based on the extracted defocus amount information.
