Actually it is a fairly complex set of algorithms for approximation
pixel matching, color replication, pixel enlargement and predicted data
overlap then we get to the calculation of accrued aberration (edge
effect). Analogous in electro-hydraulic servo system dither versus
pre-driver current damping.
Yes, the simple answer is that it IS controlled distortion, therefore
without very careful design does markedly degrade image quality.
Just my .001 cent worth.
