Abstract
A focus control apparatus includes a focus detection unit configured to detect a focus state, and a control unit configured to performing a focusing operation in accordance with the focus state and a setting value relating to the focusing operation. The control unit is configured to select a first state that allows user setting of the setting value and a second state that automatically sets the setting value according to the focus state. The control unit sets the setting value in a first setting range that is a range of the setting value that can be set by the user in the first state, and sets the setting value in a second setting range that is wider than the first setting range in the second state.
Claims8
A focus control apparatus comprising:
- at least one memory configured to store instructions;
- and
- at least one processor communicatively connected to the at least one memory and configured to execute the stored instructions to function as:
- a focus detection unit configured to detect a focus state;
- and
- a control unit configured to perform a focusing operation in accordance with the focus state and a setting value of a characteristic of the focusing operation relative to a motion of an object,
- wherein the control unit is configured to select a first state that allows user setting of the setting value and a second state that automatically sets the setting value according to the focus state, and
- wherein the control unit sets the setting value in a first setting range that is a range of the setting value that can be set by the user in the first state, and sets the setting value in a second setting range that is wider than the first setting range in the second state.
A focus control method configured to perform a focusing operation in accordance with a detected focus state and a setting value of a characteristic of the focusing operation relative to a motion of an object, the focus control method comprising the steps of:
- selecting a first state that allows user setting of the setting value and a second state that automatically sets the setting value according to the focus state;
- and
- setting the setting value in a first setting range that is a range of the setting value that can be set by the user in the first state, and sets the setting value in a second setting range that is wider than the first setting range in the second state.
A non-transitory computer-readable storage medium storing a computer program for causing a computer of a focus control apparatus that performs a focusing operation according to the detected focus state and a setting value of a characteristic of the focusing operation relative to a motion of an object to execute a control method,
- wherein the control method includes the steps of:
- selecting a first state that allows user setting of the setting value and a second state that automatically sets the setting value according to the focus state;
- and
- setting the setting value in a first setting range that is a range of the setting value that can be set by the user in the first state, and sets the setting value in a second setting range that is wider than the first setting range in the second state.
