Image capturing apparatus and control method thereof

A control method of an image capturing apparatus comprising at least one processor and/or circuitry which functions as an actuator that actuates an image sensor, a storage that stores an image signal read out from the image sensor, an image processor that processes the image signal read out from the image sensor, the method comprising

• controlling the actuator, the storage and the image processor by selectively using a plurality of operation modes,
• wherein in a first operation mode included in the plurality of operation modes, a first operation in which a first image signal is read out from the image sensor by the actuator and processed by the image processor is performed at a predetermined first cycle, and a second operation in which a second image signal is read out from the image sensor by the actuator at a timing different from the first operation and stored in the storage or a third operation in which the stored second image signal is read out from the storage and processed by the image processor is selectively performed.
