Title: Video signal amplitude control circuit
Inventor: HAYAZAKI SHINZO
IPC: H04N5/52
Filed: 1986-04-28
Abstract: PURPOSE:To output a signal having a certain amplitude by including a control voltage generating circuit which generates a control voltage based on a video signal and a control circuit which varies the degree of amplification of the video signal based on the control voltage. CONSTITUTION:The video signal inputted from a video signal input terminal 1 passes a buffer circuit 7 and is inputted to a resonance circuit 9a. The magnitude of a horizontal synchronizing signal component of the video signal is proportional to that of the video signal, and a voltage proportional to the magnitude of the synchronizing signal is generated in the resonance circuit 9a. This voltage is rectified by a diode 10 and is smoothed through a smoothing circuit 12a to generate the control voltage. This control voltage is supplied to a control circuit 13 to synchronously vary the degree of amplification of the video signal in relation to the control voltage. Thus, the magnitude of the video signal is made constant at the signal output point 14 of the control circuit 13.

Title: Pickup device

IPC: H04N13/00
Filed: 1980-07-22
Abstract: PURPOSE:To realize the picking-up of a high-quality stereoscopic image, by installing a changing means of the polarized axis into an optical path which is used for picking-up of the right and left pictures and thus receiving the optical signal in a transmission line mode. CONSTITUTION:When a vertical synchronous pulse is sent to a power supply circuit 700 from a synchronous signal generator 800, a rectangular pulse is applied intermittently to a plarized axis changing device 500 from the circuit 700 based on the TV period. According to the voltage of pulse application, both the cut-off and the transmission occur alternately for optical paths of right and left pictures. Accordingly the time series of optical signals corresponding to the right and left pictures Pl and Pr is obtained. These optical signals are sent to a pickup device 600 to be converted into electric signals. On the other hand, when the vertical synchronous pulse is sent to a mixer 900, the period of the pulse is changed to a synchronous signal having a period double as much as the TV period to be used as the reference signal in case the electric signals corresponding to the right and left pictures are discriminated. As a result, a coincidence can easily be obtained between the space between the reflector mirror in a light wave guide part and each polarizing plate in front of the reflector mirror and the space between the right and left eyes of a human being.
