Method of an apparatus for processing video signals.

摘要

0 An arrangement for processing video signals, the video signals having the form of digitally encoded samples and being arranged to produce a television picture by line and field sequential scanning includes a frame store (5), a write address generator (6) and a read address generator (8). Input video samples are fed from an input (1) to an interpolator (2) for writing into the store (5).

When a television picture is to be roated and the rotation is effected by the sequence of write addresses to the store (5) a situation can arise where there is no information available for writing into certain store locations. This results in holes appearing in the output signal where no picture related information is present. A hole detector (10) is provided at the store output and controls an interpolator (12) which inserts information derived from adjacent picture samples into the hole.
