Abstract

PURPOSE:To generate a suitable interpolating signal being free from a blur even at the time of animation by determining an interpolating signal by using several pieces of points positioned in the vicinity of some point in an image in a scanning line being adjacent to its upper and lower parts, and a signal of one field before of the same position as said point, with regard to some point in the image. CONSTITUTION:From an input signal (c), a signal c1 being as it is, a signal c2 which has been delayed by 1S by a 1S delaying device 14, and a signal c3 which has further delayed the signal c2 by total 2S through a 1S delaying device 15 are generated, and inputted to a control signal generator 19. With regard to an input signal (a), as well, in the same way as the signal (c), a signal a1 being as it is, a signal a2 which has been delayed by 1S, and a signal a3 which has been delayed by 2S are generated by using two pieces of 1S delaying devices 16, 17, and inputted to the control signal generator 19. As for an input signal (b), a signal b2 which has been delayed by 1S by a 1S delaying device 18 and inputted to the control signal generator 19. Subsequently, by using the signals c1, c2, c3, a1, a2 and a3, and the signal b2, a pattern is detected and a control signal (e) is generated. In such a way, a natural image being free from a blur even at the time of animation is reflected.
