An image processing device includes a shooting scene determining section that determines a shooting scene, a correlation evaluation value calculating section that calculates correlation evaluation values between a target pixel and surrounding pixels, a weight setting section that sets, when the shooting scene is a low correlation scene, heavy weights to the correlation evaluation value calculated from the surrounding pixels having high correlativities, an isolated-point degree calculating section that subjects the correlation evaluation values to weight addition to calculate an isolated-point degree, and an FPN correcting section that corrects a pixel value of the target pixel according to a magnitude of the isolated-point degree correction.
