A color still picture transmission system includes color visible telephones which are coupled to each other through a telephone network. In succession to luminance signal data of all picture elements forming a whole screen, respective averaged values of two kinds of color difference signal data of four picture elements being adjacent to each other are sent from the color visible telephone at a sending party to the color visible telephone at a receiving party through the telephone network, a modem and a network control unit. In the color visible telephone at the receiving party, a monochromatic still picture is first displayed on a color CRT in accordance with the luminance signal data of all the picture elements which are precedingly received and stored in a video memory, and thereafter, the monochromatic still picture is sequentially changed to a color still picture by writing the same averaged color difference signal data in storage positions of the video memory corresponding to four picture elements being adjacent to each other.
