IMAGING DEVICE AND IMAGING METHOD

An imaging device, for carrying out movie recording at a specified frame rate, comprising: an imaging sensor that repeatedly carries out imaging at a period that has been set and outputs movie image data, a control circuit that sets a second period that is shorter than a first period, based on the frame rate, and an image combining circuit for performing image combination on a plurality of image data that have been captured in the second period within the first period, using bright combination processing or dark combination processing, to generate a combined image of a single frame, wherein the control circuit performs control so as to obtain movie image data by carrying out imaging using the imaging sensor, and repeatedly carrying out generation of a combined image by the image combining circuit using the plurality of image data that have been acquired within the first period.
