Provided is a control device that includes a calculation unit that calculates, on a basis of a result of capturing a subject image passed through a focus lens by using an imaging element including a plurality of phase difference detection regions, a focus position of each of the phase difference detection regions and a determination unit that determines a position of the focus lens on a basis of an average value of the focus positions of the phase difference detection regions calculated by the calculation unit and falling within a predetermined range from the focus position on an infinity side or macro side.

Control device, control method, and electronic device to determine a lens position

Control device, control method, and electronic device

The focus detection accuracy is improved in an imaging apparatus that detects focus of each of a plurality of lenses. A main side focus control section detects, as a main side in-focus position, a main side lens position where focus is achieved in a main side detection region inside a main side image. A parallax acquisition section acquires parallax proportional to a distance by finding the distance on the basis of the main side in-focus position. A subordinate side detection region setup section sets a subordinate side detection region position in a subordinate side image on the basis of the parallax and the main side detection region position. A subordinate side focus control section detects, as a subordinate side in-focus position, a subordinate side lens position where focus is achieved in the subordinate side detection region.

Imaging apparatus, imaging module, and control method of imaging apparatus

[Object] To provide a control device capable of effectively determining a lens position even in a case where a subject close to an image capturing device and a subject far from the image capturing device simultaneously exist in a region for detecting a phase difference between subject images. [Solution] Provided is the control device including: a calculation unit configured to calculate, on a basis of a result of capturing a subject image passed through a focus lens by using an imaging element including a plurality of phase difference detection regions, a focus position of each of the phase difference detection regions; and a determination unit configured to determine a position of the focus lens on a basis of an average value of the focus positions of the phase difference detection regions calculated by the calculation unit and falling within a predetermined range from the focus position on an infinity side or macro side.

Control device, control method and electronic device

[Object] To improve both trackability of a focus position and focusing accuracy with respect to a subject. [Solution] An image capturing device includes: an imaging element having a light receiving surface including detection pixels that receive light passed through different regions of an exit pupil of an imaging optical system, and detect a phase difference between two images obtained by splitting the exit pupil; a first detection unit configured to execute at least any of first focus detection based on a phase detection autofocus (AF) method and second focus detection based on a contrast detection AF method; a focusing control unit configured to drive at least one optical member included in the imaging optical system toward a focusing position detected by the focus detection; and a second detection unit configured to detect a change in a subject image. In a case where a state in which a change amount of the subject image is less than a threshold continues for a predetermined period of time or more after the first focus detection, the first detection unit executes the first focus detection or the second focus detection.
