Abstract

A photographic or electronic camera is disclosed having an optoelectronic distance meter. Linear sensors are provided and by way of partial aperture diaphragms associated with a lens first and second images are created and projectd onto the image sensors. An evaluating circuit, in dependence upon varied position displacements of the sensor signals, determines a maximum correlation between the signals and an associated position displacement with a corresponding electrical value corresponding to distance. A stringing mirror deflects the path of rays either into the view finder or to an image plane for picture taking. The swinging mirror has apertures positioned to permit the first and second bundles of rays to pass therethrough. Deflection elements are attached to the swinging mirror and are positioned to direct the partial bundles of rays passing through the apertures such that the images are projected onto the image sensors.
