Patent ID: 7116372

Claim:
A deinterlacing method for converting an interlaced image into a progressive image, said method comprising: performing a filtering process to pixels of at least one of three fields, a deinterlacing target field to be subjected to a deinterlacing process and forward and backward fields of the deinterlacing target field within the interlaced image so as to generate an interpolation pixel for the deinterlacing target field; measuring a quantity of motion of the deinterlacing target field; and changing a filter coefficient of a filter used in the filtering process based on the quantity of the motion measured in said measuring of the quantity of motion, wherein in said changing of the characteristics of the filtering, the characteristics of the filtering are changed so that gain of components from the forward and backward fields of the deinterlacing target field is reduced as the quantity of the motion measured in said measuring of the quantity of motion is increased.
