Abstract
Abstract A system and method for adaptive interpolation of image data selects one of a plurality of different interpolation kernel functions based on one or more variables, such as a selected format for the visible presentation of the interpolated image data on an output imaging media, a selected type of the output imaging media for visible presentation of the interpolated image data, and an appearance characteristic, such as sharpness or smoothness, of the visible presentation of the interpolated image data. The system and method select an appropriate interpolation kernel function to improve an appearance of the visible presentation of the interpolated image data on the output imaging media.
