Abstract
An endoscope apparatus measures a subject using a pattern projection image of the subject on which a light and dark pattern of light is projected. The endoscope apparatus includes an insertion tube having a central axis, an image sensor, an objective optical system configured to form an image of the subject on the image sensor, an illumination light source, a pattern projector configured to project the light and dark pattern onto the subject, a projection window for the pattern projector, and an observation window for the objective optical system. The objective optical system has a prism configured to direct light incident through the observation window to a direction toward the image sensor, and the objective optical system is disposed such that an optical axis of the light directed by the prism and incident on the image sensor is offset relative to the central axis of the insertion tube.
