Abstract:
1. An image processing apparatus, comprising: an image reducing section generating at least one reduced image by generating a reduced pixel with reference to pixel values by each predetermined area of a target image which is to be processed; a noise extracting section extracting a noise component at a low frequency band according to a reduction ratio of the reduced image for each reduced pixel based on the reduced image; a noise subtraction section subtracting the noise component of the low frequency band of the reduced pixel from each of pixels at the predetermined area being referred to generate the reduced pixel; and an area smoothing section smoothing the pixels with each other at the predetermined area by a degree of smoothing according to a comparison between a strength of the noise component of the low frequency band of the reduced pixel and an image structure at the predetermined area from which the noise component is subtracted.
