ABSTRACT:
An image processing device and a method thereof. The image processing device includes a mapper to map a two-dimensional plane of an input image into a three-dimensional vector surface, a coefficient calculator to calculate a coefficient with respect to an equation of a plane formed by a plurality of pixels mapped by the mapper, and an interpolator to interpolate by calculating a gray-level of a location to be interpolated based on the equation of the plane obtained by the coefficient calculator. When the pixels on the 2-D plane are mapped into the 3-D vector space, the image processing device according to an exemplary embodiment of the present general inventive concept prevents overshoot or undershoot which may occur at the edges or on planes, and thus displays a smooth image.
