ABSTRACT:
An object of this invention is to increase the precision and speed of autofocusing operation. To achieve this object, an image sensing apparatus includes a photographing optical system which forms an object image, the photographing optical system having a focusing optical system which adjusts the imaging position of the object image, an image sensing element which photoelectrically converts the object image formed by the photographing optical system to generate an electrical image signal, an in-focus position detection device which detects the in-focus position of the focusing optical system for forming the object image on the image sensing element, on the basis of the image signal generated by the image sensing element while the focusing optical system adjusts the imaging position of the object image, and a distance measurement device which has a plurality of light-receiving portions for receiving a beam from an object, and measures a distance to the object on the basis of output signals from the light-receiving portions.
