What was it called when the luminance was discretized? I think it made things look like paint by numbers larger areas of equal luminance. Seems to me there was a project in a 1980s Radio Electronics for an analog video effects box. |

The keyword is probably "coring" it has been applied in both analog and digital domains. |

Dunno for video, but "posterize" is the relevant effect in Paint Shop. Tim |

Now to find out how that was achieved in the analog domain, a flash converter with variable bit width fed back to a DA converter? |

You could do this pretty easily with a bunch of comparators. |
