摘要： PURPOSE:To add a simple circuit to monitor the state of a camera by selectively switching two chrominance signals to supply to a modulator or providing two modulators to arbitrarily obtain a carrier chrominance signal and a recording low frequency chrominance signal. CONSTITUTION:A camera image signal from an image pickup element 1 passes a preamplifier 2, a brightness amplifier 3, a luminance signal branches, one is made an FM signal by the FM modulator 4, thereafter, multiplexed by the chrominance signal, applied to a video head 5 and recorded. The other is added by the carrier chrominance signal and thereafter, outputted to a video signal terminal 11. The chrominance signal is branched by the output of the amplifier 2, the chrominance signal is demodulated in a demodulator 6 and inputted to the chrominance modulators 7, 8. In the modulator 8, a carrier applied to a chrominance sub-carrier input terminal 10 is modulated to output the carrier chrominance signal to an addition circuit with the luminance signal. In the modulator 7, the carrier applied to a chrominance low frequency carrier input terminal 9 is modulated, thereby, a low frequency converted chrominance signal output is outputted to the addition circuit with the FM converted luminance signal.

摘要： PURPOSE: To easily display and record lapse of time with respect to an optional video image. CONSTITUTION: An image pickup device 1 converts a light from an object into a video signal. An operation section 9 is made up of switches for timer indication on/off, start/stop/reset of a timer, and a timer mode and a signal in response to the switch selection is fed to a CPU 7 of a microcomputer section 6. The CPU 7 gives a control signal to a timer 8, the timer 8 gives time information to the CPU 7, which converts time information of the timer 8 into a character code signal to be displayed and it is fed to a character generator 5. The character generator 5 converts the character code signal into a video signal, which is fed to a synthesis means 2. The synthesis means 2 gives a signal synthesizing the video signal from the image pickup device 1 and the video signal from the character generator 5 to a recorder 4 and a display device 3, which displays the synthesized video signal and the recorder 4 records the synthesized video signal.

摘要： PURPOSE: To ensure the operation at a low power supply voltage by saving a power supply required at reproduction only among power supplies required in a preamplifier section and decreasing the voltage drop across a ripple filter.
CONSTITUTION: Transistors (TR) Q
1 , Q
2 act like a normal emitter follower at the reproduction, a current whose ripple component is rejected by a resistor R
1 and a capacitor C
1 is fed to each section and the entire circuit acts like a reproduction preamplifier. A reproducing control signal is nearly at a common potential at non-reproduction, the TRs Q
1 , Q
2 are inoperative, the operation of the 1st stage amplifier section is stopped and the 2nd and succeeding sections loose the supply of the current source from the non-operating state of the current source and inactivated. The voltage drop across the resistor R
1 is the product between the resistance and the base current of the TRs Q
1 , Q
2 thereby suppressing the ripple to a sufficiently small range.
