Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is suitable for image recording and reproducing devices, particularly systems that require high-resolution, high-quality images, such as image printing applications and input devices for electronic editing. The present invention relates to an image recording and reproducing device.

(Prior art) A video signal obtained by capturing an optical image of a subject with a color imaging device can be easily edited, trimmed, and other image processing in the form of an electrical signal, and is reversible to erase low recorded signals. It has been widely used in television broadcasting, magnetic recording devices, etc. because it has the characteristic that recording and reproduction can be easily performed using a recording member having the following characteristics.

In recent years, as the demand for high-quality and high-resolution playback images has increased, new television systems such as so-called EDTV and HDTV have been proposed. Electronic video systems using video signals that can reproduce reproduced images are about to be used in fields such as printing and electronic publishing.

Typical conventional electronic video systems include: (1) Color video signals generated by a three-tube or single-tube color TV camera are recorded on a recording medium such as a VTR, semiconductor memory, or magnetic disk. (2) A method of reproducing the color video signal to obtain a color video signal.
, a method of recording on a recording medium such as a semiconductor memory or magnetic disk and reproducing it to obtain a color video signal, (3)
There is a method of obtaining a video signal using laser telecine from a color image recorded on a color photographic film of a subject photographed by a camera.

(Problems to be Solved by the Invention) Incidentally, in order to make electronic images obtained by an electronic image system usable in the field of printing, etc., an electronic image having a resolution of approximately 4000 x 4000 pixels is required. Ruga.

In the methods (1) and (2) described above, there are problems with the image pickup tube or solid-state image pickup plate and recording system that make it difficult to obtain high resolution.
The limit is to obtain a resolution of about 00x2000 pixels.

In other words, color TV cameras, which have been commonly used to generate video signals, transmit an optical image of a subject through an imaging lens to a photoelectric conversion section in an imaging device via a three-color separation optical system. It is possible to form an image, convert it into electrical image information corresponding to the optical image of the subject in the photoelectric conversion section of the image sensor, and output the electrical image information as a serial video signal on the time axis. Various types of image pickup tubes and various solid-state image pickup devices have been conventionally used as image pickup devices used in color TV cameras having the configuration described above.

By the way, in order to obtain high-quality, high-resolution reproduced images, an image sensor that can reproduce high-quality, high-resolution reproduced images and generate clear video signals is required. When the image sensor is a camera tube, there is a limit to miniaturization of the electron beam diameter in the camera tube, so higher resolution cannot be expected by miniaturizing the electron beam diameter, and the target capacity of the camera tube is smaller than the target. Since the target area increases in proportion to the target area, it is not possible to achieve higher resolution by increasing the target area.1 For example, in the case of a color imaging device for moving images, the increase in resolution of the video signal Frequency band is tens of MHz to hundreds of MHz
It is difficult to generate a video signal that can reproduce high-quality, high-resolution images using a color imaging device, for reasons such as problems with signal-to-noise ratio (S/N) as the frequency exceeds Hz. .

To explain the above point more specifically, in order to reproduce high-quality, high-resolution images and generate clear video signals using a color TV camera that uses an image pickup tube as an image sensor, it is necessary to use the image pickup tube. It is possible to miniaturize the electron beam diameter or use a large-area target, but depending on the performance of the electron gun in the image pickup tube and the structure of the focusing system, it is difficult to miniaturize the electron beam diameter of the image pickup tube. There is a limit to increasing resolution by miniaturizing the electron beam diameter, and attempts were made to obtain high resolution by increasing the target area by using an imaging lens with a large image size. In some cases, the S/N ratio of the image pickup tube output signal decreases significantly due to a decrease in high-frequency signal components in the image pickup tube output signal due to an increase in the target capacity of the image pickup tube due to an increase in the target area. Some color TV cameras using tubes cannot generate video signals that can reproduce high-quality, high-resolution images.

In addition, when a solid-state image sensor is used as an image sensor, it is necessary to use a solid-state image sensor with a large number of pixels in order to reproduce high-quality and high-resolution images. Solid-state image sensors with a large number of Since the capacitance value of the circuits used in the solid-state imaging devices has increased due to the increase in the number of pixels, such solid-state imaging devices are currently limited to 20 MHz, which is said to be the limit for the clock frequency of solid-state imaging devices. It is considered that it cannot be constructed as something practical.

In this way, in conventional color TV cameras, the image sensor used therein has a size of 1000x20 at most.
The limit is to achieve the image resolution of the HDTV system, which has a resolution of about 0.00 pixels, and it is impossible to generate a video signal that can reproduce an image with a resolution of about 4000 x 4000 pixels, which is required for electronic images. could not.

In addition, in the method (3) mentioned above, the resolution is limited by the performance of the color photographic film itself, color fading is a problem with color film, and in order to convert optical images into electrical signals, R, G.

Since three B color laser beams are required, the equipment becomes large, and color film is complicated to develop, and furthermore, the reproducibility of one color is mainly determined by the spectral sensitivity characteristics of the light-sensitive material for color film. There are drawbacks such as a small degree of freedom in color design.

After the film is exposed to an optical image of the subject, development and fixing processes are carried out to obtain a positive image on photographic paper or film within a short time).

The recording system of the above-mentioned image recording and reproducing apparatus shown in FIGS. 1 and 7 is configured with a dark box for shielding the photosensitive recording member Fi from unnecessary external light. The above-described three-color separation optical system C8S provided in the recording system of the recording/reproducing device separates the optical image of the subject into at least three optical images having different wavelength ranges, and also separates the optical image of the subject into at least three optical images having different wavelength ranges. It is constructed so that the imaging planes of the separated individual optical images can be formed in parallel on the same plane.

A perspective view of the entire three-color separation optical system C8S described above is illustrated in FIG. 12, and a plan view for explaining the principle of its construction is shown in FIG. 11. 11 and 12, 4,5°6 is an optical block,
The optical block 4 includes a dichroic mirror (R surface) that reflects red light and transmits green light and blue light, and a dichroic mirror (R surface) that reflects blue light and transmits green light and red light.

image is formed.

Then, the three imaging planes I g, I r, I b
are formed in the same plane as described above, and are arranged in a straight line.

In 8S, prism 5 extends the optical path length of red light,
In addition, the prism 6 extends the optical path length of the blue light, so that the imaging plane rg of the green light, the imaging plane Ir of the red light, and the imaging plane Ib of the blue light are arranged as described above. The amount of extension of the optical path length by the prisms 5 and 6 described above is determined by the deviation of the optical axis of each color light. equal to the quantity a,
In other words, X=a.

If the length of the optical path due to the prisms 5 and 6 is d, and the refractive index of the constituent material of the prisms 5 and 6 is n, then X = d(n-1)/ n

As in the three-color separation optical system CSS of the configuration described above, three imaging planes Ir are formed adjacent to each other in a straight line within the same plane.
, Ig, and Ib. When using a color separation optical system that forms optical images of a subject separated into individual colors, by arranging recording members at the positions of the plurality of image formation planes described above, Three high-resolution images are recorded and reproduced in parallel, but by arranging, for example, a black and white silver halide film, which has high resolution and excellent fading resistance as the recording material mentioned above, it is possible to reproduce a color image with high resolution. The advantage is that it can be easily recorded and reproduced as a high-resolution black and white image.

The three optical images color-separated by the three-color separation optical system C8S are arranged in three areas 4 a parallel to each other on the same plane.
, 5 a, and 6 a, respectively, and the image forming surfaces coincide with the photosensitive surface of the black and white photographic film F used as the photosensitive recording member F. (in the case of Fig. 1), or a plane that coincides with the photosensitive surface of the black and white instant photographic film Fi used as the photosensitive recording member Fi (in the case of Fig. 9)
Therefore, the three optical images mentioned above are formed in three regions 4a, 5a, and 6a parallel to the photosensitive surface of the black and white photographic film F (in the case of FIG. 1). The three optical images described above are recorded in three areas (Figs. 8 to 10) parallel to the photosensitive surface of the black and white instant photographic film Fi (in the case of Fig. 7). The recorded instant photographic film Fi shown in the figure (three areas corresponding to the three parallel areas 4a, 5a, 6a on the photographic paper Fi) is This will be recorded as density information.

Therefore, the above-mentioned black and white photographic film F (in the case of Fig. 1)
When the image is developed and fixed, the photographed subject becomes 0.
The color image consists of three areas 4a and 5a arranged in parallel on the same plane of film F.

6a, the color image of subject O is captured using the three-color separation optical system C8S.
It is developed and fixed as a black and white image recorded as an optical image of each color separated into three colors by the above-mentioned black and white instant photographic film Fi.
When the developing process and fixing process are applied to (the case of FIG. 7), the photographed color images of the photographed subject 0 are arranged in parallel on the same plane of the photographic paper Fi in the black and white instant photographic film Fi. Three color images of the subject ○ are placed in three areas 4a, 5a, and 6a using a three-color separation optical system C8S.
It is developed and fixed as a black-and-white image recorded by color-separated optical images of each color.

In the image recording and reproducing apparatus of the present invention, three black and white images corresponding to three optical images obtained by color-separating the color image of the object O by the three-color separation optical system C8S are recorded. Irradiate reproduction light onto black and white film F or recorded black and white instant photographic film Fi,
Individual black and white images among the three black and white images described above are reproduced as individual optical information, and the individual optical information is photoelectrically converted to generate the required time-series color signal, In each of the embodiments shown in FIGS. 2 to 4, optical information is reproduced from the recording member by the reproduction light irradiated onto the recorded black-and-white film F and the light transmitted through the recorded black-and-white film F. This shows an example of a configuration in which the reproduced optical information is photoelectrically converted to generate a required color signal, and each of the embodiments shown in FIGS. The reproduction light irradiated onto the recorded instant photographic film Fi reproduces optical information from the recording member by the light reflected by the recorded instant photographic film Fi, and the reproduced optical information is photoelectrically converted to generate the required color signal. The figure shows an example of a configuration in which the image signal is reproduced, and an example of a configuration in which a reproduced image signal is supplied to a printer to obtain a hard copy.

In FIG. 2 showing a schematic configuration of the reproduction system of the image recording and reproduction apparatus of the present invention, 9 is a laser light source that emits laser light used as reproduction light.

Reference numeral 10 denotes an optical deflector that deflects the laser beam emitted from the laser light source 9 in the main scanning direction shown by the arrow X in FIG.

The recorded black-and-white film F (sometimes simply referred to as black-and-white film F) that is to be played back is wound around a feed reel 7 and a take-up reel 8. By being rotated nine times by a winding drive mechanism (not shown), it is transferred in the sub-scanning direction shown by arrow Y in FIG. 2 according to a predetermined movement mode.

Therefore, the black-and-white images recorded in the three different recording areas 4a, 5a, and 6a on the black-and-white film F described above are produced by the laser beam deflected in the main scanning direction X and the black-and-white film F in the sub-scanning direction Y. and movement.

As a result, the laser beam transmitted through the black-and-white film F is intensity-modulated according to the optical density information recorded on the black-and-white film F, and is focused by the condensing lens 11 to the photodetector 12. The photodetector 12 outputs a time-series color signal and supplies it to the image processing device W113.
Image processing bag! ! 13, the photodetector 1 is
The time-series color signal outputted from 2 is outputted as a video signal according to a predetermined color television system.

It goes without saying that the output signal from the image processing device 13, which performs necessary signal processing, may be supplied to the printer to obtain a hard copy from the printer.

In this way, the image recording and reproducing apparatus of the present invention records the color image information of the subject on the recording member as a black and white image, and reproduces it to obtain a color signal, thereby using a single wavelength as reproduction light. Even if laser light is used, there will be no problem in reproducing color signals.

In the reproducing system of the image recording and reproducing apparatus shown in the second figure described above, three black and white images recorded in three recording areas on the black and white film F are sequentially scanned by one reproduction laser beam, and one Although this is an example of a configuration in which a sequential color video signal can be obtained from three photodetectors 12, in carrying out the present invention, three laser beams and three photodetectors are used. simultaneously scan the three black and white images recorded in the three recording areas on the black and white film F,
Of course, the image recording and reproducing apparatus may be configured so that color video signals can be obtained simultaneously from three photodetectors.

Next, in the reproduction system of the image recording and reproduction apparatus shown in FIG.
14 is a light source lamp that emits linear light used as reproduction light, 15 is a lens, and 16 is a CCD line sensor. The black and white film F to be reproduced is wound around a feed reel 7 and a take-up reel 8, and the take-up reel 8 is driven and rotated by a take-up drive mechanism (not shown). By this,
It is transported in the sub-scanning direction indicated by arrow Y in FIG.

Therefore, the black-and-white images recorded in the three different recording areas 4a, 5a, and 6a on the black-and-white film F mentioned above are captured by the CCD line sensor 1, which is scanning in the main scanning direction
The images are sequentially read linearly by the CCD line sensor 16 by the readout operation by the CCD line sensor 16 and the movement of the black and white film F, which is being moved in the sub-scanning direction Y in a predetermined movement manner.

That is, since the linear light transmitted through the black-and-white film F is intensity-modulated by the optical density information recorded on the black-and-white film F, it is sequentially read by the CCD line sensor 16. When the time-series color signal is output from the CCD line sensor 16,
This is supplied to an image processing device (not shown).The image processing device outputs the time-series color signals output from the CCD line sensor 16 as color video signals according to a predetermined color television system as described above. or perform other necessary signal processing.

In this way, the image recording and reproducing apparatus of the present invention records the color image information of the subject on the recording member as a black and white image and reproduces it to obtain a color signal. Even if light is used, there will be no problem in reproducing the color signal. Furthermore, by supplying the image-processed signal to the printer, it is possible to obtain a hard copy from the printer. Of course, it is also possible to do so.

The reproducing system of the image recording and reproducing apparatus shown in FIG. This is an example of a configuration in which sequential color signals are obtained from one CCD line sensor 16 by sequentially scanning three black and white images; however, in carrying out the present invention, three lines The three black and white images recorded in the three recording areas on the black and white film F are simultaneously scanned using a shaped lamp and three CCD line sensors.
Of course, the image recording and reproducing apparatus may be configured so that color signals of the same method are obtained from two CCD line sensors.

The light transmitted through the black-and-white film F has optical density information recorded on the black-and-white film F, and is supplied to the light-to-light conversion element PPC as writing light.

Examples of the light-light conversion element PPC include a spatial modulation element such as a liquid crystal type optical modulator, a photoconductive Pockels effect element, a microchannel type optical modulator, or an element constructed using a photochromic material. can be used,
Further, as the light-to-light conversion element PPC, one having a memory function or one without a memory function can be selected and used depending on the purpose.

can be switched to the side.

Transparent fit pole Etl in light-light conversion element PPC.

In a state where the voltage of the power supply Vs is applied to Et2 via the movable contact V and the fixed contact WR of the switch SW, the writing light WL corresponding to the black and white image on the black and white film F is converted into light. When the photoconductive layer member PCL passes through the transparent electrode Etl of the element PPC and enters the photoconductive layer member PCL, the electrical resistance value of the photoconductive layer member PCL changes in accordance with the black and white image of the black and white film F that is incident on it, thereby causing the above-mentioned A charge image corresponding to the black and white image of the black and white film F is generated at the boundary between the photoconductive layer member PCL and the dielectric mirror DML.

The charge image described above is transferred between the transparent electrodes Etl and EtZ in the light-to-light conversion element PPC by the movable contact V of the switch SW.
Erasing can be performed by setting the same potential through the fixed contact E and the erasing light EL from the transparent electrode Et2 side of the light-to-light conversion element PPC. When the erasing light EL incident from the Et2 side passes through the light modulating material layer member PML and the dielectric mirror DML and enters the photoconductive layer member PCL, the photoconductive layer member pcL changes its electrical resistance value due to the erasing light EL. decreases, and the dielectric mirror DM in the photoconductive layer member PCL
The charge image at the boundary with L is erased.

Furthermore, the charge image corresponding to the black-and-white image of the black-and-white film F, which is generated at the boundary between the photoconductive layer member PCL and the dielectric mirror DML described above, connects the movable contact V and the fixed contact WR of the switch SW. Through the light-light conversion element PPC
Transparent electrode Etl.

In a state where the voltage of the power supply Vs is applied to Et2, the light-to-light conversion element PPC is converted by inputting the readout light RL from the transparent electrode Et2 of the light-to-light conversion element PPC.
It can be read out as an optical image from the transparent type [1Et2 side of the PC].

That is, in the read mode, the light-to-light conversion element PPC
The readout light RL incident from the side of the transparent electrode Et2 is transmitted through the light modulating material layer member PML to the dielectric mirror (erasing light Et2).
The dielectric mirror (having a wavelength selection characteristic of transmitting the light L and reflecting the read light RL) reaches the DML, is reflected there, and passes through the light modulating material layer member PML again to the transparent electrode of the light-light conversion element PPC. Although the readout light RL is emitted from the Et2 side, the readout light RL that is emitted from the transparent electrode Et2 side of the light-to-light conversion element PPC after reciprocating within the light modulating material layer member PML as described above is emitted from the photoconductive layer as described above. Since the plane of polarization is changed by the electric field caused by the charge image corresponding to the black and white image of the black and white film F that is generated at the boundary between the member PCL and the dielectric mirror DML, the emitted light is passed through the analyzer 28. By doing so, the light emitted from the analyzer 28 becomes an optical image showing a change in light amount corresponding to the black and white image of the black and white film F.

By using single wavelength light as the readout light described above, a reproduced image with sufficiently high resolution can be obtained.

Therefore, in the image recording and reproducing apparatus shown in FIG. The charge image is converted into a charge image at the boundary between the member PCL and the dielectric mirror DML.

In addition, when single wavelength light is used as readout light for the charge image, the light-to-light conversion element PPC is used as single wavelength light information whose information content corresponds to the black and white image of the black and white film F.
It is emitted from.

In the reproduction system of the color image recording and reproduction apparatus shown in FIG.
The single wavelength readout light RL is obtained by deflecting the light emitted from the light source 19 in two orthogonal directions as indicated by arrows H and V in FIG. 4 by the optical deflector 21 via the lens 20. The light beam incident on the fO lens 22 and emitted from the fO lens 22 passes through the beam splitter 24 and enters the beam splitter 25.
5, the light is reflected toward the light-to-light conversion element PPC and enters the transparent electrode EtZ side of the light-to-light conversion element ppc.

The light emitted from the light-to-light conversion element PPC is converted into the black and white film F as described above with reference to FIG.
This is single-wavelength light information that corresponds to the information content of the black and white image of The light passes through the lens 26 and is photoelectrically converted by a photoelectric converter 29 located on the imaging plane of the lens 26.

The video signal output from the photoelectric converter 29 is divided into three areas 4 on the black and white film F in one horizontal scanning line.
The signal is in a sequential signal format, containing the monochrome image signals of a, 5a, and 6a in series.

This is an example of a configuration in which the optical information is reproduced and the reproduced optical information is photoelectrically converted to generate a required color signal.

Next, referring to FIGS. 8 to 10, the recorded instant photographic film Fi or recorded photographic paper Fi (hereinafter sometimes simply referred to as recorded instant photographic film F1) is irradiated. The reproduction light is reflected by the recorded instant photographic film Fi or the recorded photographic paper Fi and reproduces optical information from the recording member, and the reproduced optical information is photoelectrically converted to generate a required color signal. An example of the configuration in the case where the image signal is reproduced, and an example of the configuration in the case where the reproduced image signal is supplied to the printer to obtain a hard copy will be described.

The optical image information is recorded on recorded instant photographic films Fi and C in the main scanning performed by the CCD line sensor 16 and in the direction orthogonal to the direction of the main scanning performed by the CCD line sensor 16.
The sub-scanning is performed by moving the CD line sensor 16 relative to the COD line sensor 16, and the COD line sensor 16 outputs it as a time-series signal.

That is, the black and white images recorded in three different recording areas 4a, 5a, and 6a on the recorded instant photographic film Fi illuminated by the planar light source 33 are scanned by the CCD line sensor 16 in the main scanning direction. In addition, in the sub-scanning direction, sub-scanning is performed by relative movement between the recorded instant photographic film Fi and the CCD line sensor 16, so that the optical information recorded on the recorded instant photographic film Fi and the black-and-white film F is The density information is read by the CCD line sensor 16 and output as a time-series color signal.

The recorded instant photographic film (recorded photographic paper) Fi is irradiated with the light being deflected by a light deflector that deflects the light in two orthogonal directions, and the recorded instant photographic film (recorded photographic paper) Fi is exposed. The reflected light is supplied to a photodetector 12 through a lens 11, and the optical image information recorded on the recorded instant photographic film Fi is output as a time-series signal.

That is, the black-and-white images recorded in the three different recording areas 4a, 5a, and 6a on the recorded instant photographic film (recorded photographic paper) Fi described above are scanned by a laser beam whose light is deflected vertically and horizontally.

A color video signal in a sequential manner can be obtained from one photodetector 12 by reflecting light from a recorded instant photographic film (recorded photographic paper) Fl generated by sequentially scanning three black and white images. Although this is a configuration example, in carrying out the present invention, three laser beams and three photodetectors are used to record three records on recorded instant photographic film (recorded photographic paper) Fi. Of course, the image recording and reproducing apparatus may be configured so that three black and white images recorded in the area are simultaneously scanned and color video signals are obtained simultaneously from the three photodetectors.

As a result, the optical density information recorded on the recorded instant photographic film Fi black and white film F is read by the CCD line sensor 16 and output as a time-series color signal, and the signal is supplied to the image processing device 13.

An embodiment is shown in which the data is supplied to a printer 35 after being processed so that a hard copy 36 can be obtained from the printer 35.
