Description

Description: TECHNICAL FIELD The present invention relates to a method for recording electromagnetic radiation information.

(Prior Art) A video signal obtained by capturing an optical image of a subject by an image capturing apparatus is easy to edit, trim, and other image signal processing, and has a reversible recording member capable of erasing a recorded signal. Although it has a feature that recording and reproduction can be easily performed by using the same, an imaging device that has been conventionally generally used for generating a video signal is provided with an imaging lens to a photoelectric conversion unit in an imaging device. The formed optical image of the subject is converted into electrical image information corresponding to the optical image of the subject by a photoelectric conversion unit of the image sensor, and the electrical image information is converted into a serial video signal on a time axis. It is a well-known configuration in which various types of image pickup tubes and various types of solid-state image pickup devices are conventionally used as the above-mentioned image pickup device in the structure of the image pickup apparatus.

By the way, in order to obtain a high-quality and high-resolution reproduced image, an imaging device capable of generating a video signal capable of reproducing a high-quality and high-resolution reproduced image is required. In an image pickup apparatus using an image pickup tube as an image pickup device, there is a limit to miniaturization of the electron beam diameter in the image pickup tube, so that high resolution cannot be expected by minimizing the electron beam diameter. Since the target capacity of the tube increases in accordance with the target area, it is not possible to realize high resolution by increasing the target area. As a result, the frequency band of the video signal becomes several tens of MHz to several hundred MHz or more, which causes a problem in terms of S / N. It is difficult to generate a video signal such as may raised.

In addition, the imaging device used in the conventional imaging device is:
After the electrical signal generated by photoelectrically converting the optical information to be recorded is transmitted as a video signal, a video signal corresponding to a new optical image of the subject can be generated. Since the imaging device itself does not have a function of storing electric signals generated in correspondence with the sequential subject images, conventionally, an electric information signal obtained by imaging is recorded. When it is necessary to record the video signal generated by the imaging device, for example, using a magnetic recording device,
Since recording of the imaged contents is useful in various respects, there has been a demand for an apparatus having an image pickup apparatus having a storage function.

As one of the devices that can satisfy the above-mentioned demands, the present applicant company has a device that can capture image information and record it as a high-definition charge image on a recording medium. A device provided with a shutter that operates by applying a voltage without using a simple shutter, that is, at least a photosensitive layer member and a recording layer member disposed between two electrodes, and an optical image of a subject is captured by an imaging lens. Means for forming an image on the photoreceptor layer member, and a voltage for forming an electrostatic latent image (charge image) corresponding to the optical image of the subject on the recording layer member via the switching means to the two electrodes. An imaging device having a simple configuration having a function of storing information including an application unit has been proposed.

(Problems to be Solved by the Invention) Incidentally, since the above-described proposed imaging device does not include an optical shutter, the photoconductor layer member in the imaging device is always exposed to light.
The photoconductor used as the photoreceptor layer member is in a state where electron-hole pairs are generated by light constantly applied thereto under no electric field.

Therefore, when a predetermined voltage is applied between the two electrodes during imaging, the resolution is reduced due to the presence of electron-hole pairs generated in the photoreceptor layer member in the constant exposure state as described above. And it is difficult to set a true exposure amount.

Further, in the above-described proposed imaging device, since a configuration having a capacitance value between two electrodes is employed, a predetermined voltage is applied between the two electrodes in the imaging device during a recording operation. After the recording is performed on the recording layer member in a state where is applied, when the two electrodes are opened, the voltage charging the capacitance existing between the two electrodes remains as it is, Due to the presence of the voltage, the recorded content in the recording layer member changes,
If the surface impedance of the recording layer member is not sufficiently high, the charge charged to the above-mentioned capacitance moves in the surface direction, thereby deteriorating the resolution.

(Means for Solving the Problems) The present invention is directed to at least a photosensitive member layer member and a recording layer member disposed between a first electrode and a second electrode, between the first and second electrodes. Supply a predetermined voltage,
When the electromagnetic radiation flux to be recorded is incident on the photoreceptor layer member and the electromagnetic radiation information to be recorded is recorded on the recording layer member, the electromagnetic radiation to be recorded is The amount of exposure of the bundle to the photoreceptor layer member is set by setting the opening time of the optical shutter, and the voltage applied between the first and second electrodes during recording is set as the voltage of the optical shutter. An electromagnetic radiation information recording method including an open period, wherein an operating voltage is supplied between the first and second electrodes for a period longer than the open period of the optical shutter, and a first electrode and A predetermined voltage is supplied between the first and second electrodes in at least the photosensitive layer member and the recording layer member disposed between the second electrode and the photosensitive layer member, and the recording is performed on the photosensitive layer member. Incident electromagnetic flux Te, in the case of recording the electromagnetic radiation information that is subject to recording in the recording layer member mentioned above,
The exposure amount of the electromagnetic radiation flux to be recorded on the photoreceptor layer member is set by setting the opening time of the optical shutter, and is applied between the first and second electrodes during recording. As a voltage to be applied, a bias voltage is supplied between the first and second electrodes for a time longer than the opening time of the optical shutter, and is recorded between the first and second electrodes. Provided is a recording method of electromagnetic radiation information in which an operating voltage for recording the electromagnetic radiation information on a recording layer member is supplied.

(Operation) At least the first and second layers in at least the photosensitive layer member and the recording layer member disposed between the first electrode and the second electrode.
A predetermined voltage is supplied between the electrodes, and an electromagnetic radiation flux to be recorded is made incident on the photoreceptor layer member to record the electromagnetic radiation information to be recorded on the recording layer member. In this case, the exposure amount of the electromagnetic radiation flux to be recorded on the photoconductor layer member is set by an optical shutter.

In addition, the voltage applied between the first and second electrodes may be an optical voltage so that the photoconductor layer member and the recording layer member can operate properly between the first and second electrodes. The operating voltage is supplied between the first and second electrodes over a period longer than the above-described optical shutter opening period, and the operation voltage is supplied between the first and second electrodes. The bias voltage is applied between the first and second electrodes for a time longer than the opening time of the optical shutter as the voltage to be applied to the optical shutter, and the bias voltage is applied to the recording between the first and second electrodes. An operating voltage for recording the electromagnetic radiation information on the recording layer member is supplied.

As a result, the photoreceptor layer member operates in a state of high resolution, and recording in a good recording state is performed on the recording layer member.

Now, in the image pickup device shown in FIGS. 1 and 2, the image pickup lens during the period when the optical shutter PS is in the open state is set.

Is applied between the transparent electrode Et1 and the electrode Et2 in various setting modes as illustrated in each of FIGS. 5 to 15 (b). As the recording characteristics of the recording layer member CML of the recording medium used for recording the information signal are different according to the difference in the constituent materials of the recording layer member CML and the difference in the configuration of the recording layer member CML, etc., This is because operating conditions for performing recording in a good state may be different for each recording layer member CML, and depending on the recording characteristics of each recording layer member CML, Shutter operation timing and electrical Set the timing of the operation of the shutter, it is so that a good record can be made in the recording layer member CML.

FIG. 16 shows a voltage waveform obtained by, for example, switching the movable contact v of the switch SW in FIG. 17 on the time axis in the order of fixed contact c → fixed contact b → fixed contact a → fixed contact b → fixed contact c. The voltage waveform diagram shown in FIG. 16 corresponds to the voltage waveform diagram shown in FIG. 14 (b).

It can be easily understood that a corresponding voltage waveform can be generated. Also, by changing the manner of switching the movable contact v of the switch SW on the time axis shown in FIG.
It is also clear that voltage waveforms corresponding to the voltage waveforms shown in FIGS. 11A to 11B can be easily generated.

It should be noted that the voltage waveforms shown in (b) of FIGS. 5 to 11 indicate that the switches SW shown in FIGS. 1 to 4 are turned on and off at predetermined timings on the time axis. By doing so, it can be easily generated.

FIG. 18 shows that, when the movable contact v of the switch SW is switched to the fixed contact a, the power source Eb for bias and the power source Ea are connected in series, and information is recorded on the recording layer member CML of the recording medium. Voltage V that can be applied to terminals 1 and 2
A power supply circuit having a configuration in which a bias power supply Eb is generated between the terminals 1 and 2 when a movable contact v is switched to a fixed contact b is shown in FIG.

The switch SW in FIGS. 1 and 2 electrically disconnects the terminals 1 and 2 during the OFF period of the switch SW. However, in the circuit arrangement shown in FIG. 3, the switch SW is turned off. During the period, that is, while the movable contact v is switched to the fixed contact b side (in the case of FIG. 3), the terminals 1 and 2 are short-circuited by the movable contact v (the switch SW in FIG. 17). The same applies to the state where the movable contact v is switched to the fixed contact c). In the circuit arrangements shown in FIGS. 4 and 19, the resistance between the terminals 1 and 2 is low even during the period when the switch SW is off. Are connected by a resistor R.

As illustrated in FIGS. 3, 4, 17 and 19, information is recorded on the recording layer member CML of the recording medium between the two electrodes in the imaging device during the recording operation. After the information is recorded on the recording layer member in a state where a predetermined voltage V that can be applied is applied, the terminals 1 and 2 are connected with low impedance (naturally, a short-circuit is included. )
Since the charge that is charged in the capacitance existing between the two electrodes in the imaging device is removed, the voltage due to the charge that is charged in the capacitance existing between the two electrodes in the imaging device is removed. Point which had been a problem by the existence of
That is, the recorded content in the recording layer member changes,
Further, when the surface impedance of the recording layer member is not sufficiently high, the above-described problem that the charge charged in the capacitance spreads in the surface direction of the recording layer member and the resolution is deteriorated occurs. Can be eliminated by applying.

During the recording operation, the information is recorded on the recording layer member in a state where a predetermined voltage V is applied between the two electrodes of the imaging device so that the information can be recorded on the recording layer member CML of the recording medium. After that, a state in which the power supply Eb for the bias voltage Vb is connected between the terminals 1 and 2 (for example,
The movable contact v of the switch SW shown in FIGS. 17 and 18
Is switched to the fixed contact b), the electric charge charged to the capacitance existing between the two electrodes in the imaging device is reduced by the low internal impedance of the power supply Eb for the bias voltage Vb. Neutralized and removed,
The point which has conventionally been a problem due to the presence of a voltage due to the electric charge charged to the capacitance existing between the two electrodes in the imaging device can be solved in the same manner as in the case described above.

In the imaging device, between the two electrodes Et1 and Et2, between the low level L and the high level H in the voltage shown in each (b) of FIG. 12 to FIG. The voltage between them indicates a voltage V at which information can be recorded on the recording layer member CML of the recording medium (this point is common to FIGS. 5 to 15).
A voltage between the low level L and the middle level M is an electric field for forming a high-definition electric resistance change pattern on the photoconductor layer member PCL in the imaging device.
Is the voltage Vb to be applied to.

In FIGS. 1, 2 and 19, when the optical shutter PS is opened, the light amount of each part in the optical information to be recorded such as the optical information of the subject given to the photoreceptor layer member PCL is shown. The above-described electrostatic latent image (charge image) formed on the surface of the recording layer member CML in a state having a corresponding charge amount is obtained by transmitting light information to be recorded through the imaging lens TL to the photosensitive member. When applied simultaneously to the entire surface of the layer member PCL, the entire two-dimensional electrostatic latent image (charge image) corresponding to the entire two-dimensional optical information to be recorded is simultaneously The optical information generated and recorded on the photoconductor layer member PC
When the entire surface of L is sequentially given by the flying spot scanner, the entire electrostatic latent image (charge image) corresponding to the optical information to be recorded is sequentially generated. However, in any of the above cases, one complete charge image corresponding to the entire optical information to be recorded is formed on the photoconductor layer member PC.
After being formed on the end face of L, if necessary, the surface of the recording layer member CML of the recording medium may be
Then, the complete electrostatic latent image (charge image) corresponding to the entire optical information to be recorded on the surface of the recording layer member CML of the recording medium is formed. The area where the photoconductor layer member PC is formed
After moving to a position where it does not face the end face of L, the next subject imaging operation is performed.

As described above, complete electrostatic latent images (charge images) can be successively formed on the surface of the recording layer member CML of the recording medium. As described above, the complete electrostatic latent images (charge images) formed one by one on the surface of the recording layer member CML of the recording medium are subjected to recording given to the photoreceptor layer member PCL. Since the electrostatic latent image (charge image) has a charge amount corresponding to the light amount of each part in the optical information, the electrostatic latent image (charge image) corresponds to the photoconductor layer member PCL having a sufficiently high resolution. Since it has a high definition, by reading it out by reading means having a high resolution, it is possible to generate a video signal capable of reproducing a reproduced image with an extremely high definition.

Then, the recording layer member CML of the recording medium on which the electrostatic latent image (charge image) corresponding to the optical image of the subject is formed.
The electrostatic latent image (charge image) is read out of the image sensor by, for example, an electrostatic charge detection unit, an optical charge detection unit, or another charge detection unit, thereby obtaining high-quality and high-resolution images. It is possible to easily generate a video signal capable of reproducing a reproduced image. Examples of the above-described electric charge detection means are disclosed in JP-A-1-190178 and JP-A-1-210872. The configuration as described above can be used.
