Claim 19:
20. A method of operating an image processing device, the method comprising:
receiving pixel values of a plurality of pixels indicating an image;
detecting a plurality of target pixels in which noise is generated among the plurality of pixels;
calculating sum values of pixel values of contact pixels contacted in a vertical direction based on a position of each of the plurality of target pixels;
changing target pixel values by using respective average pixel values of the sum values;
generating an accumulation value increased by one (1) in response to odd sum values among the sum values;
determining a compensation pixel in response to changing the accumulation value from an odd number to an even number among the plurality of target pixels; and
adding a predetermined compensation value to the pixel value of the compensation pixel.
