A still picture video telephone transmission system for transmitting and receiving, via a telephone line, a still picture taken by a camera; a picture signal is transmitted and received by a transmitting circuit and a receiving circuit, to which improvements are made so as to display a still picture clearly without distortion. For this purpose, the transmitting circuit sends picture element signals together with image correcting signals such as a picture element displacement detecting signal, a phase inversion detecting signal, and settling data. The receiving circuit detects the image correcting signals in the picture element signal, and makes the necessary corrections so as to enable the still picture to be displayed in good shape.
