摘要： PURPOSE:To prevent abnormal picture from being projected on a monitor screen by alternately outputting video signals of two tracks to a device in a field cycle only when a Frame Out code is detected on a peripheral side track and a Frame IN code is detected on an internal peripheral track are detected. CONSTITUTION:When the code signal of the Frame OUT is detected on the n-th track by a recording mode identification signal (code signal) detecting means, an information signal recorded on the n-th and the (n+1)-th track is not immediately reproduced in a frame picture reproducing mode but the (n+1)-th code signal is initially detected. When the Frame IN as the (n+1)-th code signal is detected, the frame picture reproducing mode using the n-th and the (n+1)-th information signals is selected. In case except the above mentioned, for instance, the reproducing mode in which only the n-th track is successively reproduced is selected. According to an operation as mentioned above, the two filed picture of different scenes or the filed picture of a certain scene and noise of silence are not alternately reproduced on the monitor screen in the field cycle.

摘要： PURPOSE:To eliminate noise due to incident light following an exposure pulse, by deciding shutter speed by a diaphragm value, and the photometric value of a photometry circuit, and executing a reset and a transfer momentarily. CONSTITUTION:At the time of depressing a shutter button 15, a control circuit 31 controls an operation through a driving circuit 41 so as to operate the shutter function of a sensor 2 by the shutter speed decided from the brightness output of a photometry circuit 14. After completing exposure at a decided shutter speed, an image is transmitted to and recorded at a recording part 52 by the sensor reading operation of the driving circuit 41 synchronized with a recording start timing signal from the recording part 52. Thus, since it is possible to perform an entirely electronic shutter operation at any shutter speed, and at any shutter chance, a light electronic still camera without a mechanical shutter, and with high reliability can be constituted at low cost.

摘要： PURPOSE:To eliminate the influence of a transient response occurring after the discharging of a smear by making the DC voltage of the release input and the reset voltage of a feedback type pre-amp. equal to each other. CONSTITUTION:The output voltage of the feedback type pre-amp. is supplied to a reset terminal 10 as a reset voltage. At the timing when reset MOS transistors 71 and 72 turns on and the reset voltage actually is supplied to a signal line, a line selection MOS transistor is in off-state and the input terminal of the pre-amp. is in released state. Therefore, if the output voltage of the pre-amp. at the above-mentioned timing is impressed to the reset terminal as a reset voltage, the voltage is equal to the potential of the horizontal signal line after the discharging of smear charges. Accordingly, since no transient current flows, the influence of the transient response is nullified.

摘要： PURPOSE:To prevent a signal waveform from being affected by a start pulse by controlling the phase of the start pulse and the phase of readout pulses and starting reading out a signal of picture elements after a period wherein the start pulse exerts influence upon the signal waveform. CONSTITUTION:The signal of picture elements is read out of a photodetection part 4 through an output signal line 2 in a period TSC, in an elapsed time of time Tn+1 after the start pulse phiHIN goes up to a level H. At this time, the start pulse phiHIN is mixed with the signal output Sout of a solid-state image pickup element and a signal having a ringing-shaped wavelength is processed through the signal processing of a rear stage in a period TTR and then superposed upon the signal S'out of the rear stage. In this case, Tn+1>=TTR, so the start pulse phiHIN exerts no influence upon the read picture-element signal and the picture element of an image projected on a screen is not spoiled.

TH is one horizontal scanning period, THBLK is a horizontal blanking period, and TH-THBLK is a period that image signal is output. Vertical gate lines 4 are selected each one after another, one by one, from upward to downward in the diagram in one horizontal scanning period by outputs 91, 92 of vertical shift register and pulses 10, 11. Therefore, the horizontal direction lines (called horizontal picture element lines) of hot diode are read out for each one line successively.

摘要： PURPOSE:To obtain an oscillator having resistance to voltage and temperature fluctuation by stopping the oscillating operation temporarily at each TV horizontal oscillating period and controlling the oscillator so that the phase of a pulse generated at a prescribed order number from the starting point of time of the restarted oscillating operation is made always coincident with the TV period. CONSTITUTION:The phase when a pulse 14 changes from level 1 to level 0 as shown in Figure, is fluctuated as shown by a wave line to a phase (a) of a pulse 15 in response to a frequency of an oscillator output 6. In order to control the frequency of an oscillator 5 so that the phase of the pulse 14 changing from level 1 to level 0 is the phase (a) at all times, the feedback control is attained so as to keep the relation of f0=(n-1)/(T1-t), where f0 is the oscillating frequency of the oscillator 5, and T1 and (t) are time shown in Figure. The fluctuation of (t) being a cause to the fluctuation of the oscillating frequency f0 is neglected by making T1>t, and the fluctuation of the frequency due to temperature and voltage fluctuation is excluded.
