Abstract
Provided is an imaging apparatus including a mode setting unit that sets a diaphragm driving mode out of a plurality of diaphragm driving modes including a first diaphragm driving mode and a second diaphragm driving mode in which diaphragm driving is more limited than in the first diaphragm driving mode, and a diaphragm control unit that controls diaphragm driving in accordance with brightness of an imaging target in a case where the mode setting unit sets the second diaphragm driving mode.
Claims18
An imaging apparatus, comprising:
- a mode setting unit configured to set a diaphragm driving mode from a plurality of diaphragm driving modes, wherein
- the plurality of diaphragm driving modes includes a first diaphragm driving mode and a second diaphragm driving mode, and
- in the second diaphragm driving mode, a transition amount of a diaphragm mechanism for a diaphragm driving operation is less than the transition amount of the diaphragm mechanism in the first diaphragm driving mode;
- and
- a diaphragm control unit configured to control the diaphragm driving operation in accordance with a brightness of an imaging target in a case where the diaphragm driving mode is the second diaphragm driving mode.

An imaging control method, comprising:
- setting a diaphragm driving mode from a plurality of diaphragm driving modes, wherein
- the plurality of diaphragm driving modes includes a first diaphragm driving mode and a second diaphragm driving mode, and
- in the second diaphragm driving mode, a transition amount of a diaphragm mechanism for a diaphragm driving operation is less than the transition amount of the diaphragm mechanism in the first diaphragm driving mode;

An interchangeable lens, comprising:
- a diaphragm mechanism;
- a communication unit configured to:
- receive parameters indicating a diaphragm driving mode of a plurality of diaphragm driving modes, where the plurality of diaphragm driving modes includes a first diaphragm driving mode and a second diaphragm driving mode;
- and
- receive a diaphragm value;
- and
- a diaphragm driving unit configured to drive the diaphragm mechanism such that an aperture diameter of the diaphragm mechanism becomes the aperture diameter corresponding to the diaphragm value, wherein
- in the first diaphragm driving mode, the diaphragm driving unit is further configured to drive the diaphragm mechanism by asynchronous driving in which change timings of driving speed of the diaphragm mechanism do not synchronize with vertical synchronizing signals, and
- in the second diaphragm driving mode, the diaphragm driving unit is further configured to:
- drive the diaphragm mechanism at a lower speed than in the first diaphragm driving mode;
- and
- drive the diaphragm mechanism by one of the asynchronous driving, or a vertical synchronous driving in which the change timings of the driving speed synchronize with the vertical synchronizing signals.
