Abstract

PURPOSE:To reduce the time and cost required for transmission by displaying a read original on a CRT or the like for each page, allowing the operator to select whether the original is sent in color or in black/white color, storing the result in a picture memory while being divided into color and white/black pictures and sending the stored picture. CONSTITUTION:A data is displayed on a CRT 114 from a display memory 112 as a display data. The operator observes the display to discriminate whether the color data or the black/white data is to be used and a color key or a black/ white key on an operation panel 109 is entered. When the black/white key is depressed, a video i/f 103 is selected to be the color - black/white conversion mode and the picture data by one page stored in video memories 105-107 is converted into a black/white data and stored in a video memory 108. When the color transmission page is to be sent, the color notice is given to an opposite equipment and the picture data of the video memories 105-107 is sequentially sent.
