Title: Recording system for video signal
Inventor: KANEKO SHINJI
IPC: H04N5/922
Filed: 1986-12-27
Abstract: PURPOSE:To eliminate moire due to so-called pseudo gap of a ferrite head by inverting the polarity during picture period only at each horizontal period, applying FM modulation and recording the signal. CONSTITUTION:The polarity inversion (multipliers 3W, 3N, 3Y) is applied in the amplitude direction at each horizontal period for only the picture period of a video signal and the video signal is recorded while being subject to FM modulation (circuits 5W, 5N, 5Y) in the recording system of the video signal. Thus, since the moire depends on the difference of the FM carrier, the signal is always demodulated at the positive polarity, and only the moire component is eliminated excellently by adding the inverted signal at the reproduction between adjacent scanning lines having the vertical correlativity.

IPC: H05B41/32
Filed: 1992-11-19
Abstract: PURPOSE:To prevent an overexposure in a short distance side and further to suppress the generation of noise due to large current interruption or the like by supplying a current to an emitting circuit from a main capacitor while controlling a current value by a current limiting circuit. CONSTITUTION:In a microcomputer 10, an S-BUTTON signal for representing a shutter button pressed and a distance information D-INFO are received, to output a current control signal PWM relating to a current control circuit 70.

When a FILL-UP signal for representing reaching predetermined luminous energy is received from a decision circuit 130, the signal PWM is stopped. By this constitution, since the current can be interrupted in the point of time obtaining the predetermined luminous energy while supplying the current of limiting a current value to an xenon tube 100 from a main capacitor 50, an overexposure in the short distance side is prevented, and further also noise can be suppressed.
