PROBLEM TO BE SOLVED: To eliminate abnormality of a finally obtained digital picture by partially cancelling crosstalk noise generated by the second signal line of a signal line on the first signal line of the signal line. SOLUTION: An analog B signal line 64 is connected to the emitter of a transistor 76a and a current flows into a resistor 78a through a resistor 90a to boost a voltage applied to the resistor 78a in proportion. In addition, a current flowing through a transistor 80a is increased to draw more current from an analog R signal line 60. Thus, a voltage level is lowered in proportion crosstalk on the analog R signal line by drawing of increased current from the line 60. Consequently, positive crosstalk noise on the line 60 is cancelled. Thus, crosstalk noise generated by the second signal line of the signal line on the first signal line of the signal line is at least partially cancelled.
