Abstract
There is provided a focus adjustment apparatus. A first obtainment unit obtains a focus degree in a predetermined region of a shooting range. A driving unit drives a focus lens in response to an operation unit being operated. A movement amount of the focus lens per unit of an operation amount of the operation unit during the driving is lower in a case where the focus degree is greater than a focus threshold than in a case where the focus degree is lower than the focus threshold. The focus threshold is higher in a case where the focus lens is moving in a direction that increases the focus degree than in a case where the focus lens is moving in a direction that reduces the focus degree.
Claims22
A focus adjustment apparatus comprising:
- a first obtainment unit configured to obtain a focus degree in a predetermined region of a shooting range;
- and
- a driving unit configured to drive a focus lens in response to an operation unit being operated,
- wherein a movement amount of the focus lens per unit of an operation amount of the operation unit during the driving is lower in a case where the focus degree is greater than a focus threshold than in a case where the focus degree is lower than the focus threshold;
- and
- the focus threshold is higher in a case where the focus lens is moving in a direction that increases the focus degree than in a case where the focus lens is moving in a direction that reduces the focus degree.

A focus adjustment apparatus comprising:
- an obtainment unit configured to obtain a focus degree in a predetermined region of a shooting range;
- and
- a driving unit configured to drive a focus lens in a first direction in response to a first operation being made in an operation unit,
- wherein in a case where the focus degree has become a target focus degree while the first operation is underway, the driving unit stops driving the focus lens in the first direction, and in a case where the first operation is suspended and then resumed after the driving has been stopped, the driving unit resumes driving the focus lens in the first direction.
