Abstract
A scanning-line interpolation apparatus for an image represented by a plurality of blocks of picture elements, provided with a motion vector detecting circuit for detecting an inter-frame motion vector of each block of an image represented by image information of a succeeding field, from image information of preceding and succeeding fields, a judgement circuit for generating and outputting predetermined data by using a detected motion vector of each block of the succeeding field and motion vectors of corresponding neighboring blocks thereof, a mixer circuit for outputting an interpolation signal obtained by mixing an inter-field interpolation signal representing an image obtained by moving another image represented by image information of the preceding field by a distance, which is one-half the magnitude of the detected motion vector of each block of the image represented by the image information of the succeeding field, in the direction of the motion vector with an intra-field interpolation signal representing an image obtained by performing an interpolation of scanning lines of a current field by using only image information of the current field at a mixing ratio, which is changed according to the predetermined data output from the judgement circuit, and a non-interlaced signal output circuit for outputting a non-interlaced signal obtained from the interpolation signal and a signal representing the image information of the current field.
