Title: Video camera equipment
Inventor: TAKAHASHI KATSUTOSHI
IPC: H04N5/225
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To correct deviation between a video image and a voice by varying continuously a signal mixture ratio between a signal from a wireless microphone fitted to a main object and a signal from a built-in microphone fixed to a main body in linking with a zoom ratio of a lens. SOLUTION: In the case of the usual sound collection mode, a switch 17 is opened by a control signal from a system control section 8. The signal collected by this operation comes from only a built-in microphone 15. In the zoom linking sound collection mode, since the switch 17 is closed by a control signal from the system conversion section 8, an audio signal collected by a microphone section 1 of a separate wireless microphone WM fitted to a main object is FM-modulated (3). The modulated signal from the wireless microphone 1 is sent through space to an infrared ray reception section 11 of a video camera main body VC via an infrared ray transmission section 4. The signal received by the infrared ray reception section 11 is demodulated by an FM demodulator 12 and mixed with the audio signal collected by the built-in microphone 15 at an adder 18.

Title: Echo canceller circuit

IPC: H04B3/23
Filed: 1986-05-23
Abstract: PURPOSE:To form an echo canceller system digital pair cable transmission circuit adapted to short-distance transmission with simple constitution by providing plural tap circuits which are connected to respective taps of a shift register, which shifts binary transmission data, and are provided with capacitors, analog switches, etc. CONSTITUTION:When transmission data in a shift register 104 is '1', an analog switch 109 is closed, and a cancel signal of a capacitor 114 is subjected to proper level conversion and impedance conversion by a non-inverting buffer amplifier 111 while keeping the same polarity as the held voltage in the capacitor 114 and is supplied to an analog adding circuit 120. When transmission data is '0', the cancel signal has the opposite polarity and is supplied to the adding circuit 120. By this operation, an echo replica is always generated which has such polarity that a passing-round signal is cancelled. A residual echo is binarized by a comparator 118, and analog switches 107 and 108 are controlled by the output signal of each EX-QR. Consequently, the held voltage of the capacitor 114 is corrected by the result of multiplication between the output signal of the shift register 104 and the polarity of the residual echo. By this operation, the echo is always cancelled when the voltage of the capacitor 114 is supplied to an analog adding circuit 118 through amplifiers 111 and 112, etc.
