On the utter unintelligence of scanners

The following is the documentation of
  • a, a bug
  • b, the catastrophic inbuilt intelligence
  • c, heuristic un-intelligence
of my scanner used for scanning photography, the Epson Perfection V700 Photo.
I earlier used an Epson Perfection 3200 Photo scanner, and it did the same.

Surfaces of homogeneous or almost homogeneous colour are misunderstood by the scanner in big single-coloured blocks, while fine transitions of shades within them appear pixelated.

No idea why, actually, any explanations are welcome, mine is just a documentation of the thing.
