摘要： An apparatus for detecting a focused condition of an optical system, in which a light-receiving means arranged at a fixed position corresponding to a focus position photometrically detects a focused condition. A light beam having a definite shape is projected onto an object to be imaged by a light projection means. The reflected light beam is conducted along an optical axis of the optical system, deflected, and detected by the light receiving means for determining whether a focused condition exists. Several embodiments are disclosed for projecting a light spot of high contrast on the object and for detecting a focused condition on the basis of the intensity distribution of light received by the light-receiving means. The apparatus may be applied to an endoscope and other optical systems.

摘要： The photosensor is provided with a light-receiving surface for receiving a reflected image of an object and in which an aperture is provided. The aperture is positioned so as to receive a focused image and means are provided to prevent light from leaking directly to the light-receiving surface from the aperture. Prevention of light leakage permits focusing to be detected at high precision.
