摘要： PROBLEM TO BE SOLVED: To realize a drive device for a solid-state image pickup element, which is applicable for a CCD solid-state image pickup element having the same number of pixels, the same specifications for driving in a different size. SOLUTION: An output part 105 for outputting horizontal CCD drive pulses to a CCD solid-state image pickup element 102 is constituted by arranging (n) pieces (n being a plural) of three-state buffers 101 in parallel. Each buffer 101 is controlled so as to have a state according to the terminal load capacity of the CCD image pickup element 102 via a control line 103, thereby changing the drive capacity of the horizontal CCD drive pulses outputted from the output part 105. Thus, even if the CCD image pickup element 102 has a different size or different terminal load capacity, if the number of pixels and the drive specification are the same, the drive device is applicable.

摘要： PROBLEM TO BE SOLVED: To prevent the reverse transfer of charge of a vertical transferring part and the reverse flow of charge from a horizontal transferring part to a vertical CCD from occurring by making the transfer direction of signal charge which transfers the vertical transferring part the same direction in both fields. SOLUTION: First, vertical transfer (ΦV1) that is implemented twice every horizontal scanning interval is stopped in a vertical blanking interval leading (scan line number 1). Next, 15 V voltage is applied to ΦV5 after one horizontal scanning interval (scan line number 2) and charge is read from a photodiode to a vertical CCD. After the read charge is transferred in the direction of the ΦV5, ΦV2, ΦV3, ΦV4 and a horizontal transferring part, 15 V voltage is applied to the ΦV1 of the next line, charge is read from the photodiode to the vertical CCD and mixed with charge of the preceding line which is transferred, an main signal charge is acquired. About the direction of charge which is read onto the vertical CCD and transferred, both of two fields are in the same transfer direction and left-over charge does not occur.

摘要： PURPOSE: To attain lower prices and miniaturization by reducing the number of circuits for analog signal processing. CONSTITUTION: The voltage amplitude of the output signal of an analog signal processing circuit 16 which performs the analog processing of the output signal of a solid-state image pickup element 11 is detected by a digital signal processing circuit 18 which processes the output signal of an A/D converter 17 to convert the output signal of the solid-state image pickup element 11 into a digital signal, and the upper side reference voltage for A/D conversion and the lower side reference voltage for A/D conversion of the A/D converter 17 are varied so as to be proportional to the voltage amplitude of the output signal of the solid-state image pickup element 11 based on a detection result. Since the reference voltage of A/D conversion is varied fitting in the level of a signal inputted to the A/D converter 17, no gain control by analog signal processing before the A/D conversion is required, which simplifies the circuit.

摘要： PURPOSE:To obtain a stable oscillation output when an external synchronizing signal is not inputted. CONSTITUTION:This PLL circuit is provided with an internal synchronizing control voltage supplying means 20 for impressing voltage corresponding to an almost intermediate level between high and low logical levels instead of the control voltage of a voltage control type oscillator 14 when an external input synchronizing signal does not exist. Since the intermediate voltage is impressed to the oscillator 14 instead of the control voltage when the signal (a) is not inputted, almost the same oscillation condition is applied at the time of external synchronizing operation and stable oscillation can be attained. The existence of the signal (a) is detected by an external synchronizing pulse detecting circuit, the frequency-divided waveform of a frequency divider 15 is switched so as to make it a pulse string with a duty ratio '1' and the output of the frequency divider 15 is applied instead of the control voltage of the oscillator 14.
