A detecting apparatus performs focus detection using a pair of focus detecting signals obtained from an image sensor, detects flicker using a flicker detecting signal obtained from the image sensor, and controls signal readout from the image sensor. The detecting apparatus switches between a first readout state for performing signal readout for generating the pair of focus detecting signals from each of the first pixel and the second pixel, and a second readout state for performing signal readout for generating the pair of focus detecting signals from a focus detecting pixel as the first pixel and for performing signal readout for generating the flicker detecting signal from a flicker detecting pixel that is either the first pixel or the second pixel and is different from the focus detecting pixel.

Detecting apparatus, image pickup apparatus, and detecting method

An apparatus includes a device that acquires an image signal by photoelectrically converting a light beam of a subject that has entered via an optical system including a focus lens, a setting unit that sets a first region in the image signal, a focus detection unit that detects a defocus amount for each divided region of a region in the image signal, a detection unit that detects a second region as a region of a specific subject, based on the image signal, and a control unit that controls the focus lens based on the defocus amount of the divided region included in the second region if the first region and the second region overlap, and controls the focus lens based on the defocus amount of the divided region included in the first region if the first region and the second region do not overlap.

Apparatus including focusing function and method of the same

An image capturing apparatus includes a memory device that stores a set of instructions, and at least one processor that executes the set of instructions to function as, a first detection unit configured to detect a position of a gazing point in an image based on a line-of-sight of a user, a first setting unit configured to set an object detection range based on the position of the gazing point and an image capturing condition, a second detection unit configured to detect a feature area from the image, and a second setting unit configured to set a focus detection area based on a position of the feature area included in the object detection range.

Image capturing apparatus and control method thereof

An apparatus determines an object and controls driving of the focus lens based on a focus detection result.

Apparatus and method for determination of a focus detection target

A focus adjusting apparatus detects a first area of a subject and reliability of a tracking position from an image signal output from an image sensor on which a subject image is formed by an optical system, detects focus states of focus detection areas based on the image signal, determines an in-focus area for which focus adjustment of the optical system is to be performed, predicts a focus state in next focus detection based on a history of focus states of the in-focus area, and selects a second area from the focus detection areas. The first area is determined as the in-focus area in a case where a state in which the reliability is higher than a predetermined first threshold continues for a predetermined time period or longer, and the second area is determined as in-focus area otherwise.

Focus adjusting apparatus, focus adjusting method, image capturing apparatus, and storage medium

A CPU detects an image displacement amount using a signal acquired from an image sensor and converts a defocus amount using a conversion factor. The CPU predicts a future image-plane position of a moving object based on data on the defocus amount, time and a lens position. The CPU corrects the conversion factor using the data. The CPU predicts the future image-plane position of the moving object using the corrected conversion factor.
