Abstract
The present technology relates to an image processing device and an image processing method capable of reducing a used amount of a memory while suppressing deterioration in a noise reduction effect of an image. An image processing device is provided with a reduced image generation unit which reduces an original image in a stepwise manner to generate one or more n reduced images, a noise reduction unit which reduces a noise component in a predetermined frequency band of the original image, a noise extraction unit which performs processing of extracting a noise component in a predetermined frequency band from each of the reduced images in parallel, a noise synthesis unit which synthesizes noise components extracted from the respective reduced images, and a subtraction unit which subtracts a synthesized noise component from the original image after noise reduction. The present technology is applicable to, for example, an image processing device which reduces image noise.
