Identification of equivalence between line formed video images

摘要

The identification involves a pair of multiplexers (M1, M2) with inputs for identification numbers (KN1, KN2). They relate to a group of pixels within an image structure. The multiplexers also receive inputs from a counter (Z). A comparator (C) receives the identification numbers. A cycle controller (ST) generates enable signals and a pair of registers (R1, R2) address a pair of memories (RAM1, RAM2). The comparator checks points within a display line that may have the same features but have different numbers for identification.
