摘要： PURPOSE:To stabilize highly an operation by starting an automatic focus detector at a low speed only after the signals in the same directions are continuously obtd. and increasing stepwise the speed when the signal in the same direction is obtd. in succession. CONSTITUTION:Of integrated voltages VA, VB, a differential signal VA-VB is made by a subtractor 24 on one hand and a sum signal VA+VB is made by an adder 25 on the other. The differential voltage VA-VB is applied to an absolute value circuit 26 by which ¦VA-VB¦ of an optical cable 3 is obtd. Said voltage is compared with a reference value VD in a comparator 27 and the relation of whether said value is higher or lower than the reference value is outputted. On the other hand, the sum signal Va+VB is compared respectively with reference values VL, VH in comparators 28, 29 and the relation of whether said value is higher or lower is outputted. The relation of whether the integrated values VA, VB are higher or lower from each other is compared in a comparator 30 and the focusing is discriminated when VA+VB>=VH, i.e. HH=1. The starting operation of the motor in the stage of non-focusing is not immediately started The operation is started at the low speed for the beginning only after the signals of the same direction are thereafter successively and continuously generated. The touch at the start of the motor is thus largely improved and the stability of the operation is improved.

摘要： PURPOSE:To control a driving system for automatic focus detection and to eliminate malfunction by passing an output consisting of an external light component as outputs of photodetector areas and a pulse light component of a projecting element through an LPF and extracting only a DC component as the external light component. CONSTITUTION:Outputs of the areas 35A and 35B which photodetect the external light component are amplified by DC amplifiers 61a and 61b; the amplification includes down to a sufficiently low frequency and high frequency components are cut. Consequently, reflected light components of the outputs are suppressed and the amplified signals are passed through LPFs 62a and 62b to obtain complete DC signals. For the purpose, the external light components (DC component) are inputted to a differential amplifier 63 to calculate the difference, and it is discriminated whether the difference signal is larger than a constant level VC or not. When the difference is larger than V C, an object having large contrast difference which generates large difference between external light components incident on the areas 35A and 35B is judged and its output is inputted to a control circuit 51 to stop a driving motor 36 and turns on a warning lamp for display, thereby eliminating malfunction.

摘要： PURPOSE:To prevent the generation of noise by an excess of compensation by judging that a frequency of a generation of a drop out is high when an interval of the drop out is shorter than a predetermined period, and muting a modulation signal for a longer period than that period. CONSTITUTION:By a first transition of a drop out detecting circuit 7, a monostable multivibration (MM) MM 23 generates a pulse of a narrow width. This pulse is fed to an MM 24 and an AND gate 25, and the MM is triggered by a last transition of the pulse and the output thereof holds an H level for a predetermined period after triggering. When during this period, a next trigger pulse g is fed the H level is held for a further constant period. The pulse g generated from the MM during an output of the MM 24 being H is extracted out at the AND gate 25 and fed to an MM 26. An output of the MM 26 becomes a control input of a switching circuit 22, and the circuit 22 is connected to a terminal of the H side during an output of the MM 26, and an output of a muting circuit 21 is outputted to a terminal 14. Thereby, a generation of noises by an excess of a compensation of the dropout can be prevented.

摘要： PROBLEM TO BE SOLVED: To ensure data transmission and reception in terms of compression data to the utmost. SOLUTION: In a transmission source 101 it is investigated before transmission of data whether a coding system of a transmission destination 102 is coincident with a coding system of the transmission source. If coincident, then compressed data is transmitted, and if not then the data is transmitted after it is decoded. Alternatively, if a decoding system of the transmission destination 102 can be changed in response to a program, in the transmission source 101 a decoding program is sent to the transmission destination 102 prior to the data transmission, and thereafter the compression data is transmitted.

摘要： PURPOSE: To obtain an image pickup device in which a smear, etc., are hard to occur and an exposure time is adjustable by controlling exposure by means of a shutter means.
CONSTITUTION: Time measurement time T
1 of a timer changes in accordance with exposure time TE. Namely, when the exposure time TE is automatically or manually set in an exposure time setting circuit 130, TE to T
1 =TE-T
2 are operated in an operation circuit 131 and in accordance with the operation result X
00 , the time of a timer circuit 18 is changed. Consequently, regardless of the change in the exposure time, a smear during vertical transfer can be prevented. Since an exposure completion timing is set just before vertical transfer for reading, a dark current component after exposure is completed can be almost neglected. Since the time measurement time T
1 and T
2 of the timer are set so that the exposure completion timing may be just before the read timing, the dark current after exposure can be almost neglected.

摘要： PURPOSE: To obtain an image pickup device in which S/N will not deteriorate when an exposure time is short by setting an exposure control period so that it may be just before periodical reading.
CONSTITUTION: When a high level signal is outputted from an output terminal of an AND gate 17 in time t
2 , time measurement of a timer circuit 19 is executed by T
2 only. Here, (T
2 -T
1 ) is equivalent to exposure time and the (T
2 -T
1 ) is automatically set by a manual, luminance of an object, etc. In the time t
7 when from time t
2 to time T
2 pass, a pulse output is outputted from the timer circuit 19, the pulse is converted to a pulse with a prescribed level and a prescribed width by a one-shot circuit 21 and supplied to a shutter driving circuit 202. Since time measurement time T
1 and T
2 of a timer are set so that an exposure completion timing may be just before a read timing, a dark current can be almost neglected after exposure, and the dark current until exposure is started is removed by a clear action. Therefore, a picture signal with good S/N can be obtained.
