Abstract: In a focus detecting device, a plurality of distributions of quantity of light regarding the image of an object to be photographed are formed by optical means disposed on the image plane side of an objective lens by the use of light beams passed through different areas of the pupil of the objective lens. The relative positional relation between the plurality of distributions of quantity of light is found by light receiving means, and the in-focus state of the objective lens is found by the use of a signal from the light receiving means. The optical means has at least three pairs of secondary imaging lenses each forming a pair of light distributions corresponding to the image of the object to be photographed, and is constructed so that at least two of the light segments passing through the vertices of the lens surfaces of the pairs of secondary imaging lenses intersect each other and at least one other light segment does not intersect.

Abstract: A focus detection system for detecting a focus state of an object lens, includes an optical device for forming first and second light distributions corresponding to first and second images having light fluxes passing through the different parts of a pupila of the object lens. The positional relationship between the two light distributions varies in accordance with the focus state of the object lens. First and second sensors sense the first and second light distributions. A signal processor for processing output signals from the first and second sensors detect the focus state of the object lens in accordance with the positional relationships between the two light distributions. The signal processor processes the signals from the first and second sensors in accordance with a predetermined formula to obtain the positional relationship between the two images to determine a degree of coincidence of the two light distributions. The signal processing means provides an output signal in accordance with the degree of coincidence of the two light distributions.
