Claim 18:
19. The method of claim 18, further comprising:
compensating for a pixel value of a third target pixel in which the noise is generated among the plurality of pixels when the accumulation value is less than the reference value,
wherein compensating the pixel value of the third target pixel comprises:
changing the pixel value of the third target pixel by using an average pixel value of neighboring pixels included in a predetermined range of the third target pixel;
generating an additional accumulation value obtained by accumulating a third decimal fraction value, which is a value corresponding to a decimal fraction part of an average pixel value corresponding to the third target pixel, and the accumulation value; and
adding a compensation value determined based on the accumulation value to the pixel value of the third target pixel.
