This imaging device includes an imaging element, a field rate conversion processing section, and a frame rate conversion processing section. The imaging element converts an image of a photoelectric subject photographically, and outputs a picture image signal which consists of frames at a first frame rate. The field rate conversion processing section converts the picture image signal at the first frame rate into a television signal at a second frame rate which is smaller than the first frame rate. The frame rate conversion processing section converts the picture image signal at the first frame rate into a cinema film signal at a third frame rate which is smaller than the first frame rate, and which is different from the second frame rate.
