This specification discloses a distance detecting device in a camera for detecting the relative positional relation between two detection images of an object obtained by two optical systems spaced apart from each other by a predetermined base length, to thereby enable the distance from the camera to the object to be known, characterized in that the picture-taking optical system of the camera is used also as one of the optical systems.
