Claim 20:
21. An image processing device comprising:
an image sensor configured to transmit pixel values of first pixels indicating an image;
a target pixel detector configured to detect second pixels in which noise is generated among the first pixels based on the pixel values of the first pixels;
a target pixel corrector configured to change pixel values of the second pixels by using average pixel values of third pixels respectively determined according to positions of the second pixels in the image;
a target pixel compensator configured to:
an accumulation value obtained by accumulating values corresponding to a decimal fraction part of the average pixel values,
determine compensation pixels among the second pixels based on the accumulation value, and
compensate for pixel values of the compensation pixels by adding a compensation value which is determined based on the accumulation value; and

an output manager configured to output the pixel values of the first pixels including the second pixels in which the pixel values are compensated.
