Abstract

PURPOSE: To eliminate the unnatural contours of the picture image without increasing the memory capacity by reading out the data at one time corresponding to the plural continuous scanning lines and then adopting the average value of the read-out data in the form of the data corresponding to one piece of scanning line.
CONSTITUTION: The TV signal generator circuit contains picture frame memory 1 to memorize the luminance data equivalent to one picture frame of the TV video, the means to write the data into memory 1, and the means to read out the data sequentially from memory 1 in synchronization with the TV scanning. In this circuit, the reading pulses given from timing pulse generator 9 are applied simultaneously to memory 1 as well as to address counter 3 and 5, and the data corresponding to the plural continuous lines are read out at one time to shift register 2 and 4. The output of register 2 and 4 are attenuated at level attenuator 6 and 7 to be then applied to level adder 8, and then the average value is obtained for the plural data to be delivered via video output circuit 10 in the form of the data corresponding to one piece of scanning line.
