Claim 14:
15. A device for reducing noise in an input image corresponding to a color filter array of an image sensor, the device comprising:
a local window generator configured to
set, as a local window among color pixels included in the input image, a target pixel and neighboring pixels adjacent to the target pixel, and
provide color pixel values for the target pixel and each of the neighboring pixels included in the local window;

an average value generator configured to generate local color average values by averaging, color by color, the color pixel values;
a converter configured to generate offset color pixel values by converting the color pixel values of the target pixel and the neighboring pixels based on the local color average values; and
a compensator configured to generate a compensated color pixel value of the target pixel by adjusting the color pixel value of the target pixel based on the offset color pixel values.
