Patent ID: 8842930

Claim:
An image processing device comprising: a first band limiting unit configured to reduce noise included in an input image; and a restoring unit configured to perform a restoration processing on a noise-reduced image to restore image information other than the noise, the noise-reduced image being the input image subjected to a noise reduction processing in the first band limiting unit, and the image information being degraded by the performance of the noise reduction processing, wherein the restoring unit includes: a difference calculating unit configured to calculate a difference between the input image and the noise-reduced image; a predicted noise obtaining unit configured to obtain a predicted noise amount to be included in the input image; a correction signal generating unit configured to generate a correction signal for correcting the noise-reduced image and controlling an absolute value of the difference between the input image and the noise-reduced image within a range of the predicted noise amount; and an image synthesizing unit configured to correct the noise-reduced image based on the correction signal.
