An interframe coding system provided for highly efficient transmission of coded television picture signal is picture motion in response to interframe correlation detected by shifting moving blocks in a direction opposite to a motion vector detected for predicting interframe picture motion in order to reduce an amount of coded signals to be transmitted, and further improved regarding the detection of motion vector by examining interframe correlation referred to accumulated logarithms of absolute values of interframe differential picture element signals, and still further improved regarding the compensation of predicted picture motion by changing a coding threshold level in response to picture motion and further by effecting more exact secondary prediction of picture motion.; According to these improvements, an extremely high efficiency of transmission of precisely and correctly coded interframe picture signal can be attained.
