  • Image scaling
    Patent number: 6825857
    Abstract: A method and a system for scaling a digital source image consisting of a grid of X by Y pixels into a target image of a different resolution comprises the steps of/tools for: mapping the source pixels onto the target pixels; scaling the source image in the X or Y direction to produce intermediate pixels that are scaled in one direction by determining contributions to each intermediate pixel using a digital filter and accumulating the contributions for each intermediate pixel, wherein each source pixel contributes to one or more intermediate pixels and each intermediate pixel receives contributions from one or more source pixels; and subsequently scaling the intermediate pixels in the other direction by determining the contributions to each target pixel using the filter and accumulating the contributions for each target pixel; wherein each intermediate pixel contributes to one or more target pixels and each target pixel receives contributions from one or more intermediate pixels.
