Title: Image pickup device
Inventor: SAITO KUNIAKI
IPC: H05B41/32
Filed: 1993-09-28
Abstract: PURPOSE:To prevent an external power supply having a current limit for a device such as an AC adaptor from being overloaded by charging a strobe with a constant charge current during recording period of image pickup information so as to block the supply of the current to a lens drive system. CONSTITUTION:When an Ac adaptor or the like whose current supply capability is comparatively lower is used for an external power supply device, it is difficult to supply lots of currents I momentarily. When a power supply voltage Vcc is higher than a minimum voltage Vo required for the entire image pickup device, a peak current of the supply current I is preset in response to a kind of the external power supply and charging is executed in a range not in excess of the peak current. That is, the peak current is preset in a peak hold counter 4 and when an emitter current IE (supply current I) of a switching transistor(TR) 10 reaches the peak current, a reference voltage applied to a charging voltage comparator 7 is controlled to keep the current.

Filed: 1988-09-27
Abstract: PURPOSE:To decrease dispersion in manufacturing with a simple circuit and to make it possible to avoid the effect of even the voltage fluctuation of a power source by using an inverting circuit which is operated with one-phase clock pulses. CONSTITUTION:When an input signal 1 is inputted into an input terminal, the output of an inverting circuit 10 is not immediately changed. When an input clock pulse phi becomes H, the output of the circuit 10 becomes an L level first time. The output of an inverting circuit 11 becomes an H level first time when the next clock pulse phi becomes an L level. Meanwhile, a 1-bit data latch 35 determines from which of inverting circuits 14 and 18 the output is taken. At the time of an H level, the circuit 14 is selected. At this time, the signal is neglected for the input clock pulse having the width of 2-2.5 periods or less. When the data latch 35 is at the L level, the circuit 18 is selected. The pulse having the width of 4-4.5 periods or less can be detected. As shown in the above description, when the frequency of the input clock pulse is increased and the number of stages is increased, the accuracy of the detectable pulse width can be improved.
