PURPOSE:To obtain a display picture with excellent noninterlace by adding signals in a level ratio of 1/4 and 3/4 in one field and in a level ratio of 3/4 and 1/4 in other field so as to form a signal of a same scanning line with same signal processing. CONSTITUTION:An original signal to a tuner 2 and a signal obtd. by subjecting the original signal to one horizontal period delay 5 are added by an adder 9 in a level ratio of 1/4 and 3/4 in one field via a X3 amplifier 8 and added in a level ratio of 3/4 and 1/4 in other field. The sum signal is used to drive a common display element in a picture display device 10 in the one and the other fields. As a result, the signal of a same scanning line is formed by a same signal processing thereby applying excellent noninterlace display. |
