Abstract:
A computational method for converting a digitized source color image, containing at least three different colors contiguously disposed, into a second electronic color image of different effective spatial resolution, comprising:forming a scanned sequence of examination windows into said digitized color image, said examination windows being at least three pixels high and at least three pixels wide;defining a corresponding scanned sequence of elemental inferral areas smaller than, and substantially centered within, said examination windows;computing, in response to the pixels within the examination windows, at least one inferred-edge piece within at least some of said elemental inferral areas by separately computing unoriented inferred-edge pieces and separately computing an orientation to be applied to said unoriented inferred-edge prices; andcombining the said inferred-edge pieces within at least one said elemental inferral-area, with color data from the source color image, to produce one elemental unit of said second electronic color image.
