Claim:
1. An image capture device configured to capture an image of a subject and output an image capture signal, the image capture device comprising: an image capture element comprising a plurality of pixels and being configured to acquire a captured image by detecting light from the subject and converting the light into an electrical signal; an optical path changing unit configured to change an optical path of light incident on the image capture element and displace a position of light incident on the image capture element; and at least one processor configured to execute machine-readable instructions to implement: a state change determining unit configured to determine whether or not the subject temporally changes a state thereof based on a deviation of a brightness value in the captured image and, when it is determined that the subject does not change a state thereof, to output an optical path change instruction to the optical path changing unit to change an optical path of light incident on the image capture element; a correction value calculating unit configured to calculate a correction value for performing a noise elimination process corresponding to a state change of the subject using at least one of the captured image captured when the subject changes the state thereof, and the captured image obtained by changing an optical path of light from the subject not changing the state thereof in accordance with the optical path change instruction; and a correction executing unit configured to eliminate noise from the captured image by use of the correction value.
