Abstract
A focus control apparatus comprising an acquisition unit that acquires operation information of an operation member for operating a focus lens; a detection unit that detects a subject based on an image signal obtained from an image sensor; and a control unit that selects a first focus adjustment unit that performs autofocus adjustment based on the image signal or a second focus adjustment unit that performs manual focus adjustment based on operation of the operation member. The control unit selects the first focus adjustment unit or the second focus adjustment unit based on movement of the subject and the operation information.
Claims11
A focus control apparatus comprising one or more processors and/or circuitry which function as:
- an acquisition unit that acquires operation information of an operation member for operating a focus lens;
- a detection unit that detects a subject based on an image signal obtained from an image sensor;
- and
- a control unit that selects a first focus adjustment unit that performs autofocus adjustment based on the image signal or a second focus adjustment unit that performs manual focus adjustment based on operation of the operation member,
- wherein the control unit selects the first focus adjustment unit or the second focus adjustment unit based on movement of the subject and the operation information.
An image capturing apparatus comprising:
- an image sensor;
- a first focus adjustment unit that performs autofocus adjustment based on an image signal obtained from the image sensor;
- an operation member for operating a focus lens;
- a second focus adjustment unit that performs manual focus adjustment based on operation of the operation member;
- and
- a focus control apparatus comprising one or more processors and/or circuitry which function as:
- an acquisition unit that acquires operation information of an operation member for operating a focus lens;
- a detection unit that detects a subject based on an image signal obtained from an image sensor;
- and
- a control unit that selects a first focus adjustment unit that performs autofocus adjustment based on the image signal or a second focus adjustment unit that performs manual focus adjustment based on operation of the operation member,
- wherein the control unit selects the first focus adjustment unit or the second focus adjustment unit based on movement of the subject and the operation information.
A focus adjustment control method comprising:
- acquiring operation information of an operation member for operating a focus lens;
- detecting a subject based on an image signal obtained from an image sensor;
- and
- selecting a first focus adjustment unit that performs autofocus adjustment based on the image signal or a second focus adjustment unit that performs manual focus adjustment based on operation of the operation member,
- wherein the first focus adjustment unit or the second focus adjustment unit is selected based on movement of the subject and the operation information.
A non-transitory computer-readable storage medium, the storage medium storing a program that is executable by the computer, wherein the program includes program code for causing the computer to function as a focus control apparatus comprising:
- an acquisition unit that acquires operation information of an operation member for operating a focus lens;
- a detection unit that detects a subject based on an image signal obtained from an image sensor;
- and
- a control unit that selects a first focus adjustment unit that performs autofocus adjustment based on the image signal or a second focus adjustment unit that performs manual focus adjustment based on operation of the operation member,
- wherein the control unit selects the first focus adjustment unit or the second focus adjustment unit based on movement of the subject and the operation information.
