Abstract

PURPOSE:To prevent picture quality from being deteriorated at the time of converting an image having slash movement into a non-interlace image by forming a scanning line to be inserted between horizontal scanning lines based on the outputs of two delay means for delaying a TV signal and a signal delayed from the TV signal by one horizontal scanning period respectively by every prescribed number of picture elements. CONSTITUTION:The circuit is provided with a 1st multistage delay means for delaying an interlaced TV signal inputted from an input terminal 35 every prescribed number of picture elements in one horizontal scanning period and a 3rd multistage delay means for delaying a TV signal delayed only by one horizontal scanning period through a line memory 38 every prescribed number of picture element in one horizontal scanning period. Difference components between respective TV signals outputted from the 1st means and respective TV signals outputted from the 3rd means are respectively calculated and added and scanning lines to be inserted in the horizontal scanning period of the TV signals interlaced based on the picture elements of respective TV signals outputted from the 1st and 2nd delay means minimizing the added value of the difference components.
