Interpolated lines creating device for conversion of interlaced video signals to progressively swept format without interlacing

摘要

Incoming signals (1) arrive at a memory control unit (2) and memory (3) and frames pass successively through line stocking elements (4-8). During a first period of output line multiplexers (9-15) and multipliers (16-22) are used to apply coefficients and produce interpolated lines. During a second period different coefficients are applied to correct existing lines
