Abstract

PURPOSE:To eliminate picture quality degradation when a picture having the motion of an oblique line is converted non-interlacedly by generating a scanning line to be inserted between horizontal scanning lines based on the output of two delay means to respectively delay, by the prescribed number of picture elements, television signal and a signal that the television signal is delayed by one horizontal scanning period. CONSTITUTION:The title circuit is provided with a first multistage delay means to delay the interlaced television signal from an input terminal 35 by the prescribed number of the picture elements in one horizontal scanning period and a third multistage delay means to delay, by the prescribed number of the picture elements in one horizontal scanning period, the television signal delayed by one horizontal scanning period by a line memory 40. The mutual correlation of the respective television signals outputted from the first multistage delay means and the respective television signals outputted from the third multistage delay means are respectively calculated and based on the correlation value, the scanning line to be inserted between the horizontal scanning lines of the interlaced television signal is generated.
