Abstract

PURPOSE: To reproduce the intermediate tone, by corresponding a plurality of recording dots continuous toward main scanning to one video element, and by recording only a part of the dot in video element.
CONSTITUTION: The video signal A is quantized with the quantizing circuits 18 and 19, and it is sampled with the sampling pulse E, being the recording data C1 and C2, C1 and C2 are inputted to the buffer memories 22 and 23 according to the even and odd number of field discrimination signal F. The content of the memories 22 and 23 is alternately read out and recorded, constituting one video element with one dot. The sequence of the two dots constituting one video element for adjacent line is replaced, allowing to obtain the recording of intermediate tone without controlling the coloring concentration of the recording dot.
