摘要： An apparatus for detecting the focus state of an optical system has optical apparatus for forming first and second light distributions of an object. The relative positional relationship of the light distributions varies in accordance with the focus state of the optical system. A light receiving device has first and second ranges, each having a plurality of picture elements. The first and second ranges respectively receive the first and second light distributions. Operation circuitry manipulates the output signals from the first and second ranges by relatively mathematically moving them to calculate a value representing the focus state of the optical system. The operation circuitry selectively executes a first operation in which the number of signals corresponding to each other is varied, and a second operation in which the number of signals corresponding to each other is kept constant.

摘要： 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.
