Assignee: SONY GROUP CORPORATION
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 7:
8. An electronic device comprising:
an imaging optical system configured to collect light;
an imaging element configured to:
receive the light from the imaging optical system: and
capture a subject image based on the received light; and

a signal processing unit configured to process a signal output by the imaging element,
wherein the signal processing unit includes:
a calculation unit configured to calculate a focus position of each phase difference detection region of a plurality of phase difference detection regions of the subject image based on a result of the capture of the subject image,
wherein the subject image is captured by the imaging element via a focus lens; and
a determination unit configured to:
determine whether a number of phase difference detection regions, whose focus positions is within a specific range, in a set of phase difference detection regions of the plurality of phase difference detection regions is greater than or equal to a specific threshold; and
determine a position of the focus lens based on:
the determination that the number of phase difference detection regions in the set of phase difference detection regions is greater than or equal to the specific threshold, and
an average value of the calculated focus position of each phase difference detection region of the plurality of phase difference detection regions,
wherein the average value is within a specific range, on an infinity side or macro side, from the focus position.
