Abstract
A signal for a first scanning line including a picture element whose signal does not exist and a signal for a second scanning line adjacent to the first scanning line in the same field are obtained in the same period. Then, a coefficient representing the ratio of the level of the signal for the first scanning line to the level of the signal for the second scanning line is calculated. Multiplying by the coefficient the level of the signal for the second scanning line to thereby provide an interpolation signal. The interpolation signal is added to the signal for the first canning line.
