Herein disclosed is an information density decision circuit for deciding the information density of binary-coded signals within a specific section. According to the present invention, said circuit comprises first means to detect the transition points of the binary-coded picture signal, and second means responsive to detection of said transitions to count the number of the transitions of the binary-coded signal within a predetermined section being defined and to generate an output signal when said count has reached a certain value.
