ABSTRACT:
A method of changing edge sharpness of an input image being formed from input pixels having intensity levels, the method including detecting pixel-to-pixel variations in the intensity levels in at least one direction in the input image, thereby generating local pixel variation patterns; determining a localized zoom ratio based on the local pixel variation patterns; controlling edge sharpness by changing the localized zoom ratio setting interpolation points with spacing between the interpolation points varying based on the localized zoom ratio and a basic zoom ratio; and generating output pixels from the input pixel by interpolation at the interpolating points.
