Sub-pixel modification of digital images by locally shifting to an arbitrarily dense supergrid

摘要

Methods and systems may provide for receiving an input image having an input pixel density and defining a single filter based on a sub-pixel modification value, wherein the single filter has a working lattice density that is greater than the input pixel density. Additionally, the single filter and the input image may be used to generate an output image. In one example, defining the single filter includes converting the input pixel density to the working lattice density at an aperture level of the single filter.

1. A system comprising:
a memory device to store an input image having an input pixel density; a processor including,
an image receiver to receive the input image,a filter generator to define a single filter based on a sub-pixel modification value, wherein the single filter forms a lattice grid having a first set of grid lines spaced one pixel apart and a second set of grid lines within the first set of grid lines, wherein the second set of grid lines are spaced at a fine density at the sub-pixel level and provide a working lattice density that is greater than the input pixel density, andan image modifier to use the single filter and the input image to generate an output image, wherein the image sub-pixel modification value is a sub-pixel blur value; and a display device to visually present the output image.
