Summary

Description
English: Acuity/Resolution versus Hyperacuity/Localization

Top: Two stars imaged on the mosaic of retinal receptor cells can be resolved only if their separation leaves at least one intervening mosaic element with a detectably different intensity, otherwise the pattern is indistinguishable from a single elongated star.

Bottom: Two targets can be localized relative to each other to values transcending the spacing of the mosaic units; the hyperacuity mechanism achieves this by identifying, with sub-pixel precision, the light center of each target, across all the pixels it covers.
