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 intserted between horizontal scanning lines based on 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 each 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 each 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 40 for each prescribed number of picture elements in one horizontal scanning period. Respective TV signals outputted from the 1st and 3rd means are compared with each other, the most similar TV signals are averaged and the average value is successively inserted between the horizontal scanning lines of the interlaced TV signals.
