PROBLEM TO BE SOLVED: To provide an interlace scanning system video signal correction method and its device for transforming a video signal of CRT reference for transforming the signal in conformity to an LCD panel, and displaying it. SOLUTION: This interlace scanning system video signal correction method and its device store the rear part of a predetermined datum (263rd datum) of a first field of an interlace scanning system video signal, and the front part of a predetermined datum (23rd datum) of a second field, in a first memory and a second memory respectively. It is discriminated whether a video signal being received at present through an equalizing pulse section of each field is the first or second field signal. When the video signal being received at present is the first field signal, the front part of the 23rd line where a data line starts is copied from the second memory to data of the first field. When the signal is the second field signal, the rear part of the 263rd datum where the data line finishes is stored as the datum of the second field from the first memory.
