IMAGE CONVERSION APPARATUS

摘要

The apparatus calculates the intensity P of picture points (pels) in a transformed image (filtered, enlarged, reduced) from the equation …$\dots \; where\; Ii\; are\; the\; intensities\; of\; each\; of\; m\; surrounding\; pels\; (reference\; window)\; in\; the\; original\; image\; and\; alpha\; i\; the\; associated\; weight\; factors.To\; allow\; flexible\; changes\; of\; the\; conversion,\; a\; loadable\; table\; (3)\; is\; provided\; which\; contains,\; for\; selected\; pels\; in\; the\; transformed\; image\; (e.g.\; along\; a\; scanning\; line),\; the\; associated\; weight\; factors\; of\; the\; pels\; in\; the\; reference\; window\; as\; well\; as\; the\; displacement\; by\; which\; the\; reference\; window\; has\; to\; be\; shifted\; to\; calculate\; the\; next\; transformed\; image\; pel.$
