Abstract

PURPOSE: To make it possible to obtain a received picture of high quality even in case of low scanning density by equipping a method switching sub-scanning density and switching and switching method for the slice level of the output of the photoelectric converter of a transmitter interlocking to it.
CONSTITUTION: One input of voltage comparator 502 is connected to the output signal 501 line of the photoelectric converter, and the other is to the rotor of switch 503. The output of slice-level generating circuit 504 is connected directly to one stator of switch 503, and the output is voltage-divided by resistances 505 and 506 and then connected to the other stator of switch 503. Alternating switch 503 interlocking to the scanning-density alternation switch results in the changeover of the slice level. Consequently, received pictures of high quality can be obtained by the simple constitution even in case of low scanning density.
