摘要： A focus detection device includes an imaging element, a storage controller, and a focus detector. The imaging element is provided on a light path of a light flux incident via an optical system and has a plurality of pixels of charge storage type two-dimensionally arranged. The storage controller controls to sequentially store charges in pixels arranged in a first direction among the plurality of pixels and controls to sequentially store charges in pixels arranged in a second direction opposite to the first direction. The focus detector detects a focus adjustment state of the optical system based on a first output obtained when the storage controller sequentially performs storage control in the first direction and a second output obtained when the storage controller sequentially performs storage control in the second direction.

摘要： A focus detection device includes a light receiving element, an image shift detection unit, a movement detection unit, and a focus detection unit. The light receiving element receives a pair of light fluxes passing through different regions of a pupil of an optical system. The image shift detection unit detects an image shift amount caused by the pair of light fluxes, based on outputs of the pair of light fluxes received by the light receiving element. The movement detection unit detects an image movement amount caused by the optical system. The focus detection unit detects the focus adjustment state of the optical system by correcting the shift amount detected by the image shift detection unit, with the image movement amount detected by the movement detection unit.

摘要： An automatic focusing apparatus repetitively detects a defocus amount of a photographing lens, discriminates whether or not an object is moving, and calculates a pursuit correction amount for a moving object on the basis of present and previous defocus amounts. When a non-moving object is discriminated, a drive amount of the lens is calculated on the basis of the present defocus amount, and when a moving object is discriminated the drive amount is calculated on the basis of a pursuit drive amount as a sum of the present defocus amount and the pursuit correction amount. A pursuit enable/disable determining device determines whether the drive amount is calculated on the basis of the discrimination result or on the basis of the present defocus amount. When a drive direction of the lens is reversed, the pursuit enable/disable determining device causes calculation of the drive amount of the photographing lens on the basis of the present defocus amount for driving the lens in a predetermined number of drive operations after the reversal.

摘要： In an apparatus for detecting the in-focus state of a photo-taking lens of a camera, a defocus signal is produced responsive to a light intensity distribution signal and is indicative of deviation between an image of an object to be photographed and a predetermined surface. An information signal is produced indicative of the effectiveness of the defocus signal. A vignetting detection signal is produced indicative of the state of vegnetting by the photo-taking lens. The information signal is compared with a threshold value to determine the effectiveness of the defocus indicated by the defocus signal, and the threshold value is changed in response to the vignetting detection signal. A photo-taking lens may include a memory that stores data indicating an inverse of a value indicative of a distance from a predetermined plane to an exit pupil of the photo-taking lens, and the data stored in the memory may be used for calculating vignetting.
