Abstract: An imaging device includes an imaging section including an imaging sensor section of a rolling shutter system, a condition designator that sets an imaging condition using first auxiliary light which is non-visible light as an imaging condition for the imaging section and an imaging condition using visible light with the first auxiliary light as non-emitted light, and alternately designates the imaging condition and a light emission condition of the first auxiliary light at a cycle of at least two frames in a time division basis, a first light emitter that emits the first auxiliary light according to the light emission condition; and an image composer that composes a non-visible light image captured by the imaging section under the imaging condition using the first auxiliary light during a first period in which the first auxiliary light is emitted and a visible light image captured by the imaging section under the imaging condition using the visible light during a second period subsequent to the first period.

Abstract: An object of the present disclosure is to display a captured image and a shake corrected image thereof on the same screen. An imaging device is provided and has a configuration provided with a correction amount calculator that calculates a correction amount for correcting image shake in a frame image, a shake corrected image generator that generates a shake corrected image in which the image shake is corrected by performing a geometrical conversion with respect to a current frame image based on the correction amount, and a synthesized image generator that generates a synthesized image in which the current frame image and the shake corrected image are disposed on the same screen.
