A matrix panel drive control apparatus having improved display peak luminance and reduced black level luminance, permitting further improved contrast, includes a row selection circuit for selecting at least one row from among a plurality of rows of the matrix panel, a column drive circuit for supplying a modulation signal based on pixel data to a plurality of columns of the matrix panel, a clock signal supplying circuit for supplying a reference clock signal for controlling at least the pulse width of the modulation signal to the column drive circuit, and a control circuit for setting the length of the selection period and the cycle of the reference clock signal for each selected row on the basis of the pixel data. The control circuit carries out control so as to extend the cycle of the reference clock signal for a selected row having a longer selection period.
摘要:
A method of reading signals from a plurality of charge-storage devices in a charge-storage line sensor circuit so as to cause a switching device respectively corresponding to the plurality of charge-storage devices to sequentially read the stored signals and to sequentially reset the storage devices during a line read period. Dead time intervals are provided in the line read period between successive device read periods. A resetting operation for each storage device is performed in a dead time interval after the read operation for that storage device is completed.

In an information processing apparatus, at least one of recording and reproduction of information is performed while two-dimensionally scanning a recording medium with a probe, utilizing a physical phenomenon occurring between the probe and the medium. The apparatus includes a scanning mechanism for effecting relative movement between the probe and the medium so as to translate the probe as drawing a circular or elliptic locus on the medium and a recording and/or reproducing circuit for performing at least one of the recording and reproduction of information, utilizing the physical phenomenon during the relative movement.

A method for recording and/or reproducing images includes a step of performing a two dimensional scanning on a recording medium with a probe electrode which relatively returns in the X direction for the main scanning and in the Y direction for sub-scanning. The main scanning of the probe is performed at a frequency which is one positive integerth of the horizontal synchronous frequency of the image signal so as to enable the period required for returning of the probe electrode to be matched with the blanking period of the image signal. Thus, it is possible to avoid any data recording and reproducing operations during the period required for returning of the scanning probe electrode.

A recording/reproduction of information is effected using a probe electrode arranged to oppose a recording medium. A distance between the probe electrode and the recording medium is controlled by applying a voltage therebetween. A current flowing through the probe electrode upon application of the voltage is detected while the scanning is performed with the probe electrode over the recording medium. A correlation between a signal output according to the current detection and a reference signal is obtained to produce a reproduction signal from which a noise component due to an influence of an atomic step present on a surface of the recording medium is removed. The reproduction of information is effected in accordance with the generated reproduction signal.

In order to effect the reading-out of a signal from a recording medium at a high speed and without the collision of a probe electrode, the control of the spacing between the probe electrode and the signal recording layer of the recording medium is effected by sampling a tunnel current detected by the probe electrode at the timing of a reproduction clock, and reproduction is effected with this sampled value as a reference. Also, in order to effect information recording with good reproducibility and at high density, the control variable of a servo control circuit for controlling the spacing between the probe electrode and the recording layer is changed over during the periods before and after a writing pulse is applied to the probe electrode. Also, in order to effect re-recording reliably, the prior recorded state at the re-writing position is detected, and from the result of this detection, an optimal servo control variable, the waveform of a pulse voltage applied, etc. are set.

An image photodetector includes a photosensor unit, a charge storage unit, and a switch unit, all of them are formed on a single-crystal semiconductor film grown from a single nucleus such that crystal formation is performed on a substrate having a free surface including a non-nucleus formation surface and a nucleus formation surface adjacent thereto. The non-nucleus formation surface has a low nucleation density. The nucleus formation surface has a sufficiently small area to allow growth of only the single nucleus and has a higher nucleation density that that of the non-nucleus formation surface.
