摘要： PURPOSE:To reduce the vertical smear by integrating a vertical component of an object to form its image on an one-dimensional solid-state image pickup element and scanning a two-dimensional and the dimensional solid-state image pickup elements at the same time so as to subtract their outputs. CONSTITUTION:Light being made to incident through a lens 10 is divided into two at a half mirror 11 and the light quantity is set as, e.g., 90% for the two- dimensional solid-state image pickup element 12 side and 10% for a cylindrical lens 13 side. The lens 13 is arranged so as to collect vertically the light and an output of the one-dimensional solid-state image pickup element 14 becomes an integrating value in the vertical direction of the object. In operating the elements 12, 14 by the same clock pulse, a video signal including the vertical smear is obtained from the element 12 and a signal proportional to the vertical smear is obtained from the element 14. Thus, after these signals are amplified by preamplifiers 15, 16, the signals are subtracted by a differential amplifier 17, allowing to eliminate the vertical smear. Thus, the S/N ratio to the vertical smear is improved.

摘要： PURPOSE:To reduce 1/f noises of a driver element, and to obtain a solid-state image pick-up element of a high SN ratio by forming the driver of an inverter to a depletion type. CONSTITUTION:With signal charges photoelectric-converted by a photo diode 1, the signal charges corresponding to lateral one line are transferred collectively to a charge transfer element 7 through each transfer gate 5 from each vertical signal line 4 during a horizontal blanking period, and stored in each memory. The element 7 is driven during a horizontal scanning period, and signals are read in succession from an output amplifier 8. An inversion circuit by MOSFETs 10 and 20 improves charge transfer efficiency to the transfer element from the signal line 4. 1/f Noises reduce in the MOSFET when a channel is formed in an Si bulk and the exchange of electrons between a surface state and the channel is reduced. Accordingly, when a driver element 20 forming the inversion circuit is formed to the depletion type, 1/f noises are reduced, and the solid-state image pick-up element of the high SN ratio is obtained.

摘要： PURPOSE:To obtain the smear component with high S/N by stopping a horizontal charge coupling element and operating a vertical charge coupling element only after all signal charges of one field are read out, in an interline charge coupling solid-state image pickup device. CONSTITUTION:When the signal charge from all lines is read out of a CCD 3 after the end of one field period, the signal charge is not included in the uppermost line 31 of the vertical CCD yet. But, the smear component leaked while the charge is transferred as 3N-31 in the vertical CCD is stored therein. Thus, when a pulse phiH of the horizontal CCD is stopped and the transfer for a line's share is performed to the vertical CCD with a pulse 31' of phiv1, phiv2, for example, after the signal charge is transferred from the photoelectric converting element to the vertical CCD with a switching pulse 25, the smear nXs multiplied by (n) is outputted to the output signal 24' during the 1st one horizontal period, by repeating the transfer of the vertical CCD transfer and the readout by the horizontal CCD with pulses 21', 22', 23.

摘要： PURPOSE:To confirm a recording result without reproducing it by a reproducing device, by adding an error detecting circuit to a recording device, and displaying whether recording is executed exactly or not, or raising an alarm. CONSTITUTION:A signal of an image pickup device 1 is sampled by one frame portion, is amplified by a recording amplifier 3, and thereafter, is recorded by a recording magnetic head 4. Subsequently, an output of a head 7 is amplified by a reproducing amplifier 9 and is inputted to a signal processing circuit 10. This signal is displayed on a display 13 of an electronic view finder having an afterglow property or a liquid crystal, etc. As for these displays, it is necessary to make it as small as possible in order to make a camera small-sized and light- weight, for instance, it is desirable to use a liquid crystal whose number of picture elements in the horizontal and vertical directions is reduced to 1/N. Also, an output of the signal processing circuit 10 is led to an error detecting circuit 14 and counted, and when its counting value becomes below a set value, a built-in LED is made to emit light.

摘要： PURPOSE:To obtain an excellent video signal, by injecting a bias charge from a sweep-out drain when sweep-out a pseudo signal from a capacitor supplied with the bias charge, and from a charge transfer element when readout the signal. CONSTITUTION:A pseudo signal such as vertical smear leaked to a vertical signal line 6 is transferred from the signal line 6 to a storage section 14 efficiently by using a bias charge supplied from a bias charge storage section 14. The bias charge is applied from a pseudo signal sweep-out drain 12 to the storage section 14, and the pseudo signal from the storage section 14 is swept out from the drain efficiently. The bias charge applied from a storage section 7 again is used to transfer the signal charges from the signal line 6 to the storage section 7. The signal charge is read out from the storage section 7 to the charge transfer element by using the bias charge inputted to the charge transfer element in advance. The transfer efficiency of charges from the storage section 7 is improved with the operations like this, the mixture of the pseudo signal to the signal charges is prevented and excellent picture quality is obtained even at a low illuminance.

摘要： PURPOSE:To detect optical signals only without fixed pattern noise, by providing the optical signals including the fixed pattern noise and the fixed pattern noise itself separately in CTDs at the horizontal blanking period and taking the signal difference during the horizontal scanning period. CONSTITUTION:A vertical signal line 4 is swept out at the initial stage of a horizontal blanking period and excessive charges not signals are swept out externally through a gate 10. The charges remained are read in the CTD13 via gates 5, 6 and 11 as the fixed pattern noise. The charges remained on a vertical signal line 4, a picture element (a) and optical signal charge for lateral one line's share are read to the CTD8 through the gates 5 and 6. The signals read in the CTDs 8 and 13 are outputted only for the optical signal component via a differential amplifier 15.

摘要： PURPOSE:To remove a fixed noise pattern while securing the sweep of an excess noise charge, by storing temporarily the electric charge, which is charged into an element from an excess electric sweep terminal, in the capacity between this terminal and a vertical signal line. CONSTITUTION:An n area 15 existing between a gate connected to a gate terminal TX2A of a MIS transistor TR and the gate of a MIS TR connected to a gate terminal TX3A constitutes a buffer capacity Cz. In this constitution, the time of turn-on and rise of a power supply terminal BLDA of a blooming suppressing circuit is later than the time of turn-off and fall of a gate terminal BLGA. At this time, the terminal TX3A is low-level. By this operation, the bias charge from the terminal BLDA is stored in the gate capacity of the gate TX2A and the capacity Cz. Thereafter, when the terminal TX2A is turned on and the terminal TX3A is turned on, the charge stored in the gate TX2A and the capacity Cz is transferred to a vertical signal line 4 to act as a bias charge for sweeping away the excess charge.

摘要： PURPOSE:To obtain a larger value of resistance to the horizontal flow of the electric charge of a separated region than that of a photoelectric converting region, by setting the thickness of a photoconductive film of the separated region between picture elements smaller than the gap between the picture element electrodes and setting the resistance of said photoconductive film at a large value. CONSTITUTION:The photoconductive thin films 15-1, 15-2 and 15-3 are formed separately from each other, and a transparent electrode 8' is formed on these photoconductive films. At the same time, the picture element electrodes 6'-1, 6'-2 and 6'-3 are formed separately from each other. The thickness of the photoconductive film of the picture element separated region is set smaller than the gap between the picture element electrodes. As a result, the photoconductive thin film has a resistance higher than the resistance between the transparent electrode and the picture element electrodes both in the horizontal and vertical directions and between the picture elements. This reduces the charge quantity caused by the optical charge which is generated from the photoconductive thin film and flows into the contiguous picture element electrode in the horizontal direction.
