Abstract: PURPOSE:To reduce time delay generated at the time of shifting a mode from an idle read mode to a light receiving mode, by providing a control means which supplies electric charge accumulated in a prescribed capacitive element to the coupling capacitor of a photoelectric transducer when at least two or more vertical scanning lines are scanned simultaneously. CONSTITUTION:Capacitors C1...Cm are connected to one ends of signal read lines l1...lm via MOS switches Tc1...Tcm, and the switches Tc1...Tcm are connected to the output terminals of a control circuit 3 via a reset signal line LRS, and their ON and OFF operations are controlled by a reset signal SRS outputted from the control circuit 3.

Therefore, it is possible to shift the mode to the light receiving mode from a time when the generation of the final vertical scanning signal line Svn based on the pulse CK-1 is completed, consequently, to set the mode at the light receiving mode earlier than ever. Also, since the capacitive element is formed outside a light receiving area, the high density and high integration of a picture element can be realized.

Title: Adjusting method for ac measuring apparatus
Inventor: KAMATA ICHIRO
IPC: G01R19/25
Filed: 1992-05-20
Abstract: PURPOSE:To shorten the time for adjustment by obtaining the zero-point correcting value of an amplifier circuit for equalizing the positive and negative areas of an AC input signal for a specified time, and obtaining the amplitude correcting value of the amplifier circuit for making the input signal, whose zero point is corrected, equal to a theoretical value. CONSTITUTION:A certain value is inputted into input terminals 1 and 2. The value is made to be VR. An adjusting switch 23 is depressed. The AC input signal undergoes A/D conversion for a specified time at a specified period in a CPU 20. The zero-point correcting value and the amplitude correcting value of an amplifier circuit 3 are obtained. Namely, the zero-point correcting value is determined so that the positive and negative areas of the waveform of the AC input signal become equal. The amplitude correcting value is determined by obtaining the effective value of the AC input signal, whose zero point is corrected, in the specified time and making the value become a logical value VR. Both correcting values are stored in a non-volatile memory 25. The AC input signal in a measuring mode is inputted through the terminals 1 and 2 and made to pass through the amplifier circuit 3 and an A/D converter 19. The true value V is computed in the CPU 20 by using the zero-point correcting value and the amplitude correcting value, which are stored in the memory 25. Therefore, an adjusting circuit is not required, and the time of the adjustment performed in the CPU 20 is shortened.
