Signal converting method and circuit for television receiver

摘要

A signal converting circuit is disclosed for converting a television signal for 2:1 interlaced scanning system to another television signal for 1:1 non-interlaced scanning system using line memories for storing image data of two adjacent scanning lines of a present field and field memories for storing image data of a last occurring field. An interpolation signal is produced by controlling a value of the televisions signal of the two adjacent scanning lines in response to the television signal of the two adjacent scanning lines in the present field and the television signal of a scanning line positioned between the two adjacent scanning lines in the last occurring field.
