摘要:
An information processing apparatus for accumulating image information consisting of n pixels and effecting the processing of output of the information is provided with a plurality of memory devices, a distributing device and an output control device. The information is stored in the plurality of memory devices. By the distributing device, the image information consisting of the n pixels are divided into m pixel unit basis (n>m), and the information consisting of the m pixels into a p (m>p) pixel unit basis, and the plurality of information each consisting of the p pixels are distributed to the plurality of memory devices. Upon the output of the image information, the information stored in the plurality of memory devices are selectively outputted by the output control device.

A recording/reproduction of information is performed on a recording medium using a probe as follows. The relative movement between the probe and the recording medium along a track groove of the medium is performed on the basis of a predetermined drive signal. A voltage is applied to between the probe and the recording medium. A tunnel current flowing through the probe upon application of the voltage is detected so as to detect the track groove. A correction signal for correcting the drive signal is obtained on the basis of fuzzy deduction. The probe and the recording medium are driven relative to each other along the track groove in accordance with a drive signal corrected by the correction signal.

An image information processing apparatus for processing image information includes a total curvature calculating unit, mean curvature calculating unit, a logical product computing unit and a median filter. A total curvature at each pixel of the image information is calculated by the total curvature calculating unit. A mean curvature at each pixel of the image information is calculated by the mean curvature calculating unit. The logical product computing unit executes computation of a logical product of outputs from the total curvature calculating unit and the mean curvature calculating unit. An output from the logical product computing unit is filtered by the median filter.
摘要:
An information recording/reproducing apparatus effects recording of information by moving a probe close to a recording medium and scanning a surface of the medium parallelly with the probe, reading out information by using a micro signal obtained from a physical phenomenon occurring in the scan. The apparatus is provided with plate electrodes and a capacity detecting device. One of the plate electrodes is formed on a substrate which supports the probe. The other plate electrode is formed on a substrate which supports the recording medium. A capacity between the plate electrodes is detected by the capacity detecting device. A gap between the probe and the recording medium is controlled in accordance with the detection result.

An information processing apparatus effects at least one of recording, reproduction and erasure of information on a recording medium having a track groove by use of a probe electrode. Relative movement between the probe electrode and the recording medium is effected by the moving mechanism. A predetermined driving signal is inputted to the moving mechanism so that a predetermined movement of the probe electrode to the groove track is effected. The physical phenomenon caused between the probe electrode and the recording medium is detected, so that the track groove is detected and a correction value for correcting the movement of the probe electrode from the driving signal on the basis of the timing of the detection. The moving mechanism is controlled on the basis of the driving signal and the correction value.
摘要:
An information processing apparatus for effecting recording of information on and/or reproduction of information from a recording medium is provided with a probe electrode, a cantilever piezo-electric member, a controller and a detector. The probe electrode is relatively displaced to the recording medium by the cantilever piezo-electric member. The controller applies a control signal to the cantilever piezo-electric member to control the cantilever piezo-electric member. The detector detects a minute signal obtained on the tunnel effect caused between the probe electrode and the recording medium. A switch element is further provided on the apparatus so as to electrically disconnect between the cantilever piezo-electric member and the controller during the minute signal being detected by the detector.
