Abstract
The present invention provides a circuit of eliminating motional vector remaining caused by transmission error, comprising : an input terminal for inputting an interframe motional vector; first delay device 42 connected to the input terminal, for delaying the interframe motional vector as much as a predetermined time; a zero detector 43 connected to the input terminal and to the first delay device 42, for detecting that both the delayed interframe motional vector and the interframe motional vector are continuously in zero state more than a predetermined number; and a switch 47 connected to the zero detector, for forcibly outputting zero('0') just in case that the zero detector detects zero more than the predetermined number.
