摘要： A one-dimensional image sensor comprising a solid image pick-up element takes images in sequence, and generates an image signal. Clock pulses from a frequency variable type clock pulse generator having a frequency which varies in correspondence to a control signal are supplied to a one-dimensional image sensor, thereby image signals are outputted in sequence. The image signal is amplified by an amplifier and inputted to a comparator and compared with a reference signal. A frequency variable range of the frequency variable type clock pulse generator is set higher than the cut-off frequency of the amplifier, and the binary level output by the comparator is substantially the same as the image inputted to the one-dimensional image sensor and control is effected by the variable frequency of the clock pulses.

摘要： A liquid-crystal display device of a simple matrix type is permitted to present a liquid-crystal display of good display quality free from nonuniformity in display brightness. A method of driving a liquid-crystal display device wherein voltages which correspond to potential differences between scanning voltages from a Y drive circuit and display voltages from an X drive circuit are applied to liquid-crystal cells at intersection points between scanning electrodes (Y electrodes) and data electrodes (X electrodes), thereby presenting a display conforming to display data comprises the steps of providing a correction time period for correcting the display voltage to be output from the X drive circuit at least once every scanning period of one line, and outputting a correction voltage at a voltage level which is intermediate between a voltage level in an ON-display state and a voltage level in an OFF-display state instead of the display voltage from the X drive circuit within the correction time period.

摘要： In a half tone display driving circuit for a liquid crystal matrix panel, a pulse for half tone display is phase modulated so that pulse signals which are out of phase relative to each other are applied to adjacent columns of the liquid crystal matrix panel, or from the phase-modulated pulse a gray scale pulse (tone pulse) is prepared in which the frequency of occurrence of voltage edges is decreased. The dephased pulse signals or the gray scale pulse (tone pulse) is used to prevent a decrease in brightness of display when the liquid crystal matrix panel is driven for half tone display.
