Provided is an imaging device capable of generating a desired synthesized image at an imaging stage without applying a processing load. A viewfinder device (10) provided in a digital camera (1) has a function of superimposing and displaying information on an optical viewfinder image to be observed from a viewfinder eyepiece portion. In a case where a synthesis target image is pasted on a captured image to generate a synthesized image, the synthesis target image is displayed on the optical viewfinder image in a superimposed manner. A layout of the synthesis target image is adjusted by an operation of an operation unit (6). Further, the synthesis target image is automatically processed based on an image to be captured.
