Abstract
An imaging apparatus can mount a lens device, which is an external device, on the main body thereof. The main body includes a shake detection unit that detects a shake amount and a power supply fluctuation detection unit that detects a fluctuation in power supply supplied from a power supply unit to the lens device. A frequency calculation unit calculates a driving frequency of the lens device based on the fluctuation in power supply during lens driving. If the driving frequency of the lens device interferes with the driving frequency of the shake detection unit, the system control unit inhibits or restricts a function using the shake detection unit.
Claims12
An imaging apparatus that can mount an external device on a main body comprising:
- at least one processor and at least one memory functioning as:
- a first detection unit configured to detect a shake of the main body;
- a power supply unit configured to supply a power supply from the main body to the external device mounted on the main body;
- a second detection unit configured to detect a fluctuation in the power supply;
- a calculation unit configured to calculate a driving frequency of the external device based on the fluctuation in the power supply detected by the second detection unit;
- and
- a control unit configured to perform control that avoids or suppresses an influence on a function that has used the first detection unit caused by the driving frequency of the external device, which has been calculated by the calculation unit, interfering with a driving frequency of a detector used for detecting the shake of the main body by the first detection unit.
A control method executed by an imaging apparatus that can mount an external device on a main body comprising, the method comprising:
- detecting a shake of the main body by a first detection unit;
- supplying a power supply from the main body to the external device;
- detecting a fluctuation in the power supply by a second detection unit;
- calculating a driving frequency of the external device by a calculation unit based on the fluctuation in the power supply detected by the second detection unit;
- and
- performing control that avoids or suppresses an influence on a function that used the first detection unit caused by the driving frequency of the external device, which has been calculated by the calculation unit, interfering with a driving frequency of a detector used for detecting the shake of the main body by the first detection unit by a control unit.
