Abstract
PURPOSE: To make even a dynamic interlace picture into a non-interlace picture without degrading the quality of the picture by taking a composited picture between frames or from one frame in accordance with the result of comparison between a preliminarily determined value and the value obtained by integrating the difference between two continuous frames of the interlace picture. CONSTITUTION: A difference device 4 calculates the difference between contents of frame memories 1 and 2 through a changeover switch 10 and sends it to an integrator 5, and the integrator 5 integrates this signal for one frame. A comparator 6 compares the output of the integrator 5 with an independently held reference value and sends the result to a non-interlace control circuit 7. That is, a composited picture between frames of the interlace picture is taken when the output is smaller than the reference value in the comparator 6, but a composited picture from one frame of the interlace picture is taken when it is larger than the reference value. Thus, even the dynamic interlace picture is made into a non-interlace picture without degrading the picture quality.
