Abstract
An image processing device including: a decision pixel manager for setting a decision area for a defect candidate pixel, and determining a first decision pixel and a second decision pixel, based on first phase information of pixels included in the decision area with respect to a first modulation frequency of a sensing light source among the pixels; a target pixel determiner for calculating a phase difference between the first decision pixel and the second decision pixel, based on second phase information of the pixels with respect to a second modulation frequency of the sensing light source, and determining the defect candidate pixel as a target pixel, corresponding to that the phase difference exceeds a predetermined reference value; and a phase corrector for changing a phase of the target pixel, based on the phase difference.
