An imaging device able to simplify an optical system while maintaining a high frame rate, but without needing expensive blurring restoration processing hardware, able to reduce costs, and in addition capable of obtaining a restored image little influenced by noise, and a method of same, which bypasses blurring restoration processing of an image processing device 150 by a switching unit 140 to perform camera signal processing of a camera signal processing unit 160 at the time of a through image and performs blurring restoration processing at the image processing device 150, then performs camera signal processing at the camera signal processing unit 160 to display the image only at the time of capturing an image.
