Abstract
An optical apparatus configured to control driving of a diaphragm unit includes a setting unit configured to set a target position of an aperture blade in a diaphragm unit according to a zoom state, and a control unit configured to control a driving velocity of the diaphragm unit according to a residual driving amount by which a position of the aperture blade becomes the target position.
Claims7
An optical apparatus configured to control driving of a diaphragm unit, the optical apparatus comprising:
- a processor configured to:
- set a target aperture position of aperture blades in the diaphragm unit according to a zoom state;
- and
- control a driving velocity of the diaphragm unit according to a residual driving amount by which an aperture position becomes the target aperture position,
- wherein the processor changes, while the diaphragm unit is driving towards a first target aperture position corresponding to a first zoom state, the target aperture position to a second target aperture position corresponding to a second zoom state different from the first zoom state so that the diaphragm unit does not stop at the first target aperture position.
A control method for an optical apparatus that controls driving of a diaphragm unit, the control method comprising the steps of:
- setting a target aperture position in the diaphragm unit according to a zoom state;
- and
- controlling a driving velocity of the diaphragm unit according to a residual driving amount by which an aperture position becomes the target position,
- wherein while the diaphragm unit is driving towards a first target aperture position corresponding to a first zoom state, the target aperture position is changed to a second target aperture position corresponding to a second zoom state different from the first zoom state so that the diaphragm unit does not stop at the first target aperture position.
A non-transitory computer-readable storage medium storing a computer program executable by a computer to execute a control method for an optical apparatus that controls an aperture position of a diaphragm unit zoom state, wherein the control method comprises the steps of:
- setting a target aperture position in the diaphragm unit according to a zoom state;
- and
- controlling a driving velocity of the diaphragm unit according to a residual driving amount by which an aperture position becomes the target position,
- wherein while the diaphragm unit is driving towards a first target aperture position corresponding to a first zoom state, the target aperture position is changed to a second target aperture positon corresponding to a second zoom state different from the first zoom state so that the diaphragm unit does not stop at the first target aperture position.
