Method and device for displaying of a lineflicker reduced graphic signal on a television display which is operating with interlaced line scanning

摘要

The method involves writing the line step-free graphic signal into an image memory (12) and reading out as a line step signal, subjecting it to vertical filtering and displaying the filtered signal. The pixels of the graphic signal are compared with one or more vertically adjacent pixels after being read out of the image memory to determine the need for vertical filtering and associating markers indicating checked pixels. An Independent claim is also included for an arrangement for reproduction of line flicker-reduced graphic signal on TV display operating with line step reproduction.
