Abstract
A wipe solid generator has a first memory with one memory location for each pixel during the active interval of a line of a video signal and a second memory with one memory location for each active line during a field of a video signal. A processor calculates numerical values, loads numerical values into the first and second memories, and reads numerical values from the first and second memories synchronously with a video signal. An arithmetic section carries out a combinational arithmetic operation on numerical values read from the memories and provides an output wipe solid signal dependent on the result of the operation.
