FIELD: information technology.
SUBSTANCE: image processing method comprises steps on which the image received from an image sensor, having a pixel region shielded from light and a pixel region which is not shielded from light, is broken into two or more frequency components; the noise value is calculated for the frequency component from the frequency component in the pixel region shielded from light; the noise component is suppressed for the frequency component in the pixel region which is not shielded from light in accordance with the calculated noise value; and the broken frequency component is synthesised so as to form the image that way. The invention also discloses devise which realise the said method.
EFFECT: reduction of noise arising during image processing.
