IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD

摘要

An image processing device (100) includes: a first band limiting unit (10) that reduces noise included in an input image; and a restoring unit (20), wherein the restoring unit (20) has a difference calculating unit (21) that calculates a difference between the input image and a noise-reduced image, a predicted noise obtaining unit (26) that obtains a predicted noise amount to be included in the input image, a correction signal generating unit (22) that generates 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 (23) that corrects the noise-reduced image based on the correction signal.
