御装置。 It has a conversion means that scans a medium on which an image is recorded line by line and outputs a black and white image signal read from the image in each unit scan, and a memory that stores the image signal. In an image signal transmission control device that stores an image signal to be output in the memory and reads out the image signal from the memory at a predetermined period according to the transmission speed of the line, the memory for storing the image signal is divided into a first and a second memory. The image signal for each unit scan is stored in the first memory.
or a means for supplying an image signal to the second memory, a readout means for reading out the image signal from the first or second memory, and a means for supplying the image signal to the readout side or the readout means at a predetermined period. switch means connected to the image signal supply side, for controlling the supply of the image signal for each unit scan to one of the first or second memory and the readout of the image signal from the other memory. For one memory, unit scanning of the recording medium is performed a plurality of times, black and white image signals from the first scanning are supplied and stored, and black image signals detected by the converting means are supplied for the next scanning. 1. An image signal sending control device, which corrects an image signal stored in a memory, and reads out the image signal from another memory connected to an image signal reading side.
