Patent JP-H03214962-A (JP)
Title: Drive method for solid-state image pickup device
Inventor: HAYAKAWA YOSHIHIRO
IPC: H04N5/341
Filed: 1990-01-19
Abstract: PURPOSE:To prevent deterioration in picture quality and to make the device small by driving analog shift registers through the use of pulses synchronously with each other entirely in order to prevent deviation of production periods of signals to be synchronized in the main scanning direction from being interfered with a voltage signal when the integration time controlled by a shift gate differs from each of photosensing element array. CONSTITUTION:Biphase transfer clocks phi1A1-3 and phi2A1-3 synchronously with each other are used for the method. Thus, all the biphase transfer clocks are stopped while any of main scanning synchronizing signals phiSH1-3 is generated. For example, when no main scanning synchronizing signal phiSH1 is generated, not only the biphase transfer clocks phi1A1, phi2A1 but also the other biphase transfer clocks phi1A2-3 and phi2A2-3 are simultaneously stopped. Since discontinuous parts are generated at the entirely same period by using the pulses as above for the drive, occurrence of crosstalk is prevented.

Title: System and apparatus for transmitting pcm signal
Inventor: TANAKA SUSUMU
IPC: H04B14/06
Filed: 1985-01-23
Abstract: PURPOSE:To prevent effectively a deviation of a DC component due to correction to missing of a differential data caused by a transmission error by transmitting a differential data and an absolute PCM data under a prescribed condition while switching them. CONSTITUTION:An analog original signal given to an input terminal 1 is sampled at an A/D converter 2 by using a sampling frequency fS and given to a difference device 3. The difference device 3 takes sequential difference of the given original sample data and gives an output of a difference data in, e.g., 15-bit. The difference data and the original sample data outputted from the A/D converter 2 are given to a selector 4. A discriminator 5 selects whether the analog original signal is transmitted in the form of DC-PCM or in the NI- PCM. Then the data selected by the selector 4, that is, the difference data or the original sample data is given to an NI encoder 6, where quasi-momentary compressing processing is applied.

Title: Time base correction device
Inventor: YOSHINAKA TADAAKI
IPC: H04N9/83
Filed: 1989-01-19
Abstract: PURPOSE:To correct a time base fluctuation component of an input digital signal with simple circuit constitution by correcting a clock phase through readout based on a reference clock signal and correcting a phase of a block synchronizing signal through the readout based on a reference clock synchronizing signal. CONSTITUTION:A 1st first-in first-out memory means 3 synchronizes a clock phase of an input digital signal with a reference clock signal and a 2nd first-in first-out memory means 6 synchronizes a phase of a block synchronizing signal of an input digital signal with a reference synchronizing signal. That is, when a parallel data signal is stored in the 1st FIFO memory 3, since the phase of a reference write start pulse WSP fed to the 1st FIFO memory 3 and the phase of a write clock WCL are not arranged, there is a possibility of deviation of the phase of a reset timing of the 1st FIFO memory 3 by one clock, but the deviation is absorbed by the 2nd FIFO memory 6. Thus, the time base fluctuation component of the input digital signal is corrected with simple circuit constitution.

Abstract: PURPOSE:To linearly vary from the maximum attenuation to the minimum attenuation of a semiconductor variable resistor by a single positive power supply by using a bias circuit utilizing a division circuit comprising an opera tional amplifier circuit and a resistor so as to bias gates of two FETs and source of one FET properly. CONSTITUTION:A voltage given to an attenuation control terminal 113 is given to a gate terminal of an FET 104 via a resistor 104 and a gate potential of an FET 102 is decided by an operational amplifier circuit. The characteristic of the operation circuit is decided based on a reference voltage fed to a noninverting input terminal of the operational amplifier and the slope is decided by the ratio of resistances of resistors 112 and 109. Thus, in selecting the ratio of the resistances of the resistors 109, 112 and the ratio of resistances of resistors 105, 119, 120 to a proper value, the degree of change with respect to the attenuation control voltage is uniformized. Thus, the voltage changing direction of the gate terminal voltage of the FETs 101, 102 is made opposite and the change from the maximum to the minimum attenuation is attained.

Abstract: PURPOSE:To extract accurately the motion of a picture in a composite color television signal, by lowering the motion detection sensitivity for the edge part, where the malfunction of motion detection is easy to occur, of the composite color television signal to discriminate a still picture correctly as a still picture. CONSTITUTION:Through te output signal of a BPF21 includes high frequency components of the luminance signal of the still picture and luminance high frequency components and chrominance components of an animation picture, chrominance components of the still picture are eliminated. Though the output signal of a BPF22 includes chrominance components of the still picture and luminance high frequency components and chrominance components of the animation picture, the luminance high frequency components of the still picture are eliminated. Consequently, when outputs of BPFs 21 and 22 are multiplied in a multiplying circuit 25, the multiplication result approximates zero in case of the still picture; but in case of the amination picture, a signal which has luminance high frequency components and motion information corresponding to the level difference between frames of a color difference signal is obtained. This signal is added to the output of an LPF23 by an adding circuit 26 to obtain a signal corresponding to motion information in an output terminal 27.
