Claim 0:
1. An image processing device comprising:
a target pixel detector configured to detect a plurality of target pixels in which noise is generated among a plurality of pixels included in an image sensor;
a target pixel corrector configured to change target pixel values of the plurality of target pixels, by using average pixel values of neighboring pixels of each of the plurality of target pixels; and
a target pixel compensator comprising a compensation determiner configured to determine compensation pixels to which a compensation value is added to a pixel value among the plurality of target pixels based on the accumulation value,
wherein the target pixel compensator is configured to compensate for the target pixel values by using an accumulation value obtained by accumulating values corresponding to a decimal fraction part of the average pixel values.
