    "Photoshop and other image processing software
    all does this as standard today. Post-processing to generate sharpness in
    excess of the image sensor's ability is standard today. We know the job can
    be done in software.
    So, why shouldn't a processor like the human brain also be able to run a
    similar program?"
    Apparent 'sharpness' only is improved by such software - not resolution - by
    increasing the contrast (making dark edges darker, light edges lighter)
    where the edge of one shape abuts another.
    As to whether the brain can do something similar I don't know, but it's a
    fascinating idea.
