Abstract
Systems, methods, and other embodiments associated with image scaling are described. According to one embodiment, a method includes acquiring a set of amplitude values describing pixels in an image. A target pixel is identified from the set of pixels and a preceding pixel is identified to the target pixel. An amplitude range of amplitudes is defined between the amplitude of the preceding pixel and the target pixel. The method determines whether the interpolation between the preceding pixel and target pixel will result in an interpolated pixel having an interpolated amplitude outside of the amplitude range. An interpolation slope is determined that reduces overshoot or undershoot in interpolation pixels generated between the target pixel and the preceding pixel.
