Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spatial light modulator (SLM) for converting a film image or the like taken by a camera into a spatial light modulator (SLM).
The present invention relates to an image display device for viewing through a storage display means such as a light modulator.

[0002]

2. Description of the Related Art Generally, a film photographed by a camera is developed and printed on photographic paper and viewed as a photograph. However, recently, a film image is electronically read by a film scanner or the like, and the film image is read. Devices that can view electronic images on a television or the like are commercially available. Since a conventional device of the same type does not have an image storage unit, the power is turned off.
Sometimes the displayed film image is erased.

On the other hand, the present applicant has disclosed in Japanese Patent Application Laid-Open
Japanese Patent Application Laid-Open No. 790 proposes an image display device in which a film image photographed by a camera is stored in a spatial light modulator, and the image can be viewed by displaying the film image.

This image display device illuminates a photographed and developed film from behind with a light source such as a xenon tube, and projects the transmitted light to a spatial light modulator through an enlarged projection optical system including a projection lens and a reflection mirror. To write a film image.

Here, the spatial light modulator is composed of a ferroelectric liquid crystal, a photoelectric conversion film and the like, and the written image information can be stored for a long time by the memory function of the ferroelectric liquid crystal.

FIG. 18 shows a configuration of a transmission type spatial light modulator. The spatial light modulator 10 includes a photoelectric conversion film 74.
Color filter 76 and transparent electrode 7 coated with
A ferroelectric liquid crystal 73 is sealed between a glass substrate 77 having a transparent electrode 72 and a glass substrate 77 having a transparent electrode 72. The spatial light modulator used in the image display device proposed in Japanese Patent Application Laid-Open No.
One of the transparent electrodes is patterned, and is configured to control an electrode to which a voltage is applied according to a screen size.

When a viewer views a film image photographed by a camera or the like using the image display device, the spatial light modulator on which the film image is written is projected in the direction in which the film image is projected using a fluorescent lamp or the like (see FIG. Backlight from the middle right direction). The viewer can view the film image by looking at the light transmitted through the spatial light modulator. At this time, if the element is configured such that a portion where light is applied to the photoelectric conversion film becomes black, display by negative / positive inversion can be realized.

[0008] Also, Japanese Patent Laid-Open No. 5-19359 discloses that
There has been proposed a photo printing apparatus (printing apparatus) that reads trimming instruction information stored in a negative film and performs a trimming processing print based on the information. This printing apparatus performs printing by variably setting the position of the film with respect to the projection optical axis and variably setting the magnification of the projection optical system based on the trimming information of the film.

[0009]

However, in the conventional image display device using the spatial light modulator, it is possible to change the display image to a predetermined screen size, but the displayed image is not changed. Cannot be displayed again by specifying an arbitrary trimming range.

In a conventional printing apparatus, a trimming processing print is performed based on trimming instruction information already recorded on a magnetic recording portion or the like of a film, while checking a negative / positive inverted and enlarged image of the film. The trimming range cannot be input at any time.

Further, in the conventional printing apparatus, since only a part of the image projection surface is limited by the print frame based on the trimming instruction information recorded on the film and printing is performed, the effective surface of the photographic paper is used. The image projection plane is not used efficiently.

Furthermore, in the conventional image display apparatus and printing apparatus, it is impossible to change the trimming information while checking the image of the film which has been negatively / positively inverted and enlarged, or to record the trimming information on the film. .

As described above, the conventional image display devices and printing devices are inconvenient for trimming images.

The SLM 10 has a configuration in which a ferroelectric liquid crystal 73 and a photoelectric conversion film 74 such as an organic photoconductive film are laminated. When a voltage is applied to the ferroelectric liquid crystal layer 73 and the photoelectric conversion film 74 via the transparent electrodes 72 and 75 by the SLM drive circuit 101 shown in FIG. 6, the voltage is divided by the resistance of the ferroelectric liquid crystal layer 73 and the photoelectric conversion film 74. The applied voltage is applied to each layer. At this time, the SLM drive circuit 101 applies a voltage to the SLM 10 so that the voltage applied to the ferroelectric liquid crystal layer 73 becomes lower than the threshold voltage at which the ferroelectric liquid crystal molecules are inverted.

At this time, when the SLM 10 is irradiated with light, an electric charge is generated in the light-irradiated region of the photoelectric conversion film 74, and the resistance of the photoelectric conversion film 74 decreases. as a result,

Next, the operation of the image display device 1 configured as described above will be described with reference to the flowcharts of FIGS.

First, the CPU 100 executes the signal input / output circuit 1
It is confirmed whether or not the cartridge chamber lid opening / closing button 22 has been pressed through 05 to open the film cartridge chamber lid (# 201). When the viewer presses the cartridge chamber lid open / close button 22 to newly load the film 12 for viewing on the image display device 1, the CPU 100
Sets the flag "Flag1" indicating whether the film cartridge 35 is attached to or detached from the apparatus 1 to "1"(# 224). Here, the flag “Flag1”
When the value is “0”, it indicates that the film cartridge 35 is not attached or detached, and when the value is “1”, it indicates that the film cartridge 35 is attached or detached.

Thereafter, the CPU 100 waits until the main switch 21 is changed from "off" to "on" by the viewer (# 202). When the main switch 21 is changed to “on” by the viewer (# 202),
The CPU 100 detects the state via the signal input circuit 105 and sends a signal to the fluorescent lamp lighting circuit 102 to turn on the fluorescent lamps 50 and 51 (# 203). Part of the illumination light from the fluorescent lamps 50 and 51 is converted into substantially parallel light by the reflection shades 60 and 61 in a cross section parallel to the paper surface.
The SLM 10 is uniformly illuminated via the reflection mirror 42.

Further, the illumination light transmitted through the SLM 10 is
The angle of view is changed by the transparent substrate 11 having the lens-shaped body disposed near the light exit surface of the SLM 10. Thereby, the viewing angle with respect to the viewer is widened.

Is compared with a preset time T0 (# 204).
When the counted time T is shorter than the preset time T0, the CPU 100 continuously checks the display content displayed on the liquid crystal display element 27 selected by the display switching button 23 via the signal input circuit 105.

Each time the viewer presses the display switching button 23, "non-display mode" → "frame number display mode" →
The operation mode of the device and the liquid crystal display element 27 in the order of “time display mode” → “time setting mode” → “non-display mode”
Of the CPU 10 are switched.
A value of 0 allows the user to confirm the setting state of the display content via the signal input circuit 105.

If the display content of the liquid crystal display element 27 is not set to the "time setting mode"(# 205), the CPU 100 further checks the value of the flag "Flag 2" indicating whether or not the frame number of the film is being set. Yes (# 206).
When the value of the flag “Flag2” is “0”, it indicates that the frame number of the film image to which the viewer writes the image is not being set, and when the value is “1”, the viewer can change the frame number of the film image. Indicates that setting is in progress.

If the viewer is not setting the frame number of the film image to be written to the SLM 10 (# 206), the CPU 1
00 confirms the display mode of the liquid crystal display element 27 again.
If the display mode of the liquid crystal display element 27 is "time display mode"(# 207), the CPU 100 sends a signal to the LCD drive circuit 106 to display the time on the liquid crystal display element 27 (# 226).

On the other hand, if the display mode of the liquid crystal display element 27 is "frame number display mode"(# 208), C
The PU 100 sends a signal to the LCD drive circuit 106 to display the frame number on the liquid crystal display element 27 (# 209). At this time, the frame number displayed on the liquid crystal display element 27 is SL
This is the frame number of the film image written in M10. The frame number of the film image written in the SLM 10 is stored in the EEPROM 110.

If the display mode of the liquid crystal display element 27 is "non-display mode"(# 208), the CPU
100 sends a signal to the LCD drive circuit 106 to prevent the liquid crystal display element 27 from displaying (# 218).

When the mode check is completed in this way, C
The PU 100 checks the state of the main switch 21 again via the signal input circuit 105 (# 210). If the main switch 21 is not "off", the CPU 100 checks via the signal input circuit 105 whether the cartridge chamber cover open / close button 22 has been pressed (# 211).

If the viewer presses the cartridge chamber cover open / close button 22 to change the film to be viewed (#
211), the lid of the cartridge chamber is opened by a cartridge chamber lid opening / closing mechanism (not shown), and the flag “Flag1” indicating the film cartridge attaching / detaching state is set to “1” assuming that the viewer has replaced the film cartridge 35. (# 219). At this time, the CPU 10

The fluorescent lamps 50 and 51 which illuminated 0 from behind are turned off.

On the other hand, if the viewer has not pressed the cartridge chamber lid opening / closing button 22 or the cartridge chamber lid is not open (# 211), the CPU 100 checks the lighting state of the fluorescent lamps 50 and 51 (# 2). 21
2). If the fluorescent lamps 50 and 51 are not lit, C
The PU 100 sends a signal to the fluorescent lamp lighting circuit 102 to turn on the fluorescent lamps 50 and 51 (# 213). As described above, the lighting state of the fluorescent lamps 50 and 51 is controlled by the open / close state of the lid of the film cartridge chamber. It is possible to recognize that the lid of the cartridge chamber remains open.

Further, the CPU 100 is connected to the signal input circuit 10
It is confirmed whether or not the viewer has input the trimming position information by pressing the touch pen 2 against the touch panel 9 via # 5 (# 214).

If the viewer has not input the trimming position information using the touch panel 9, the CPU 10
0 is an image writing button 2 via the signal input circuit 105
It is checked whether 5 has been pressed (# 215).

Even if the viewer presses the image writing button 25 by mistake (# 215), the CPU
100 executes a film image writing operation according to the flow of the "image writing" subroutine shown in FIG. 8 (# 222).

In this "image writing" subroutine,
First, the CPU 100 confirms whether or not the frame number of the film is being set by the viewer (# 240). A flag "Flag" indicating whether or not the film frame number is being set.
If "2" is a value of "0" and the viewer has not set the frame number of the film (# 240), the CP
In U100, the film cartridge 35 is the image display device 1
It is checked whether or not the film cartridge is loaded in the film cartridge chamber (# 241).

The loaded state of the film cartridge 35 can be detected based on the output signal of a light emitting / receiving element (not shown) arranged on the side of the film cartridge chamber. The CPU 100 causes a light emitting element such as an infrared light emitting diode to emit light in order to read a bar code written on the outside of the film
The reflected light from is received by a line sensor such as a CCD. The CPU 100 checks whether or not the film cartridge 35 is loaded in the film cartridge chamber based on the output of the light receiving element such as a line sensor, and detects the identification information of the film from the bar code information.

If the film cartridge 35 is not loaded in the film cartridge chamber (# 241), the CP
U100 sends a signal to LCD drive circuit 106 to cause liquid crystal display element 27 to display "OUT", and warns the viewer that film cartridge 35 is not loaded (# 249). Then, after warning that the film cartridge 35 is not loaded for a while is displayed, the process returns to the main routine of FIG. 7 (# 263).

On the other hand, if the film cartridge 35 is loaded (# 241), it is confirmed whether or not the frame number of the film is displayed on the liquid crystal display element 27 (# 24).
2). If the frame number of the film is not displayed on the liquid crystal display element 27 (# 242), the film cartridge 35
After checking the attachment / detachment state, the frame number of the film is displayed on the liquid crystal display element 27.

More specifically, the CPU 100 sets a flag “Flag” indicating the detached state of the film cartridge 35.
The value of "1" is confirmed (# 243). The flag "Flag
If the value of “1” is set to “0” and the film cartridge 35 is not detached after the film image is written to the SLM 10 (# 243), the CPU 100 stores the currently set frame number in the EEPROM 110, S
The frame number of the film already written is assigned to the LM 10 (# 244). Therefore, the viewer can set the frame number of the film based on the frame number of the film written in the SLM 10.

On the other hand, if the value of the flag “Flag 1” is set to “1” and the film cartridge 35 is attached / detached after the film image is written to the SLM 10 (# 243), the CPU 100 determines the frame number currently set. Is substituted for "0"(# 248). For this reason, viewers are required to start SLM1 from the first frame of the newly loaded film.
It is possible to set the frame of the film image to be written to 0.

Further, the CPU 100 sets the value of the flag "Flag2" indicating whether or not the frame number of the film is being set, to
The frame number is set to the value of "1" being set (# 245), and a signal is transmitted to the LCD drive circuit 106 to display the frame number being set on the liquid crystal display element 27. The frame number is displayed (# 246).

Further, the CPU 100 resets the time T after the viewer has set the frame number of the film to "0", and then starts counting time again (# 247). Then, the process returns to the main routine of FIG. 7 (# 263).

As described above, even if the image writing button 25 is pressed, the CPU 100 recognizes that the viewer has inadvertently pressed the image writing button 25 in a state where the frame number of the film is not displayed on the liquid crystal display element 27. And SLM
No writing of the film image to 10 is performed.

In many cases, the CPU 100 takes the liquid crystal display element 2 into consideration in consideration of the fact that the viewer intends to rewrite the film image and presses the image writing button 25.
In the state where the film frame number is not displayed on 7, the writing of the film image is not performed, but the frame number of the film is displayed on the liquid crystal display element 27 in preparation for writing the film image. The viewer confirms the frame number displayed on the liquid crystal display element 27 and waits until the image writing button 25 is pressed again.

When returning to the main routine from the "image writing" subroutine, the CPU 100 compares the time T measured after the operation for setting the frame of the film with the preset time T0 (# 204). If the counted time T is shorter than the preset time T0, the CPU 100 subsequently confirms the display content displayed on the liquid crystal display element 27 selected by the display switching button 23 via the signal input circuit 105 ( # 20
5).

If the display content of the liquid crystal display element 27 is not set to the "time setting mode"(# 205), the CPU 100 further checks the value of the flag "Flag 2" indicating whether or not the frame number of the film is being set. Yes (# 206).

If the viewer is setting the frame number of the film image to be written into the SLM 10 (# 20)
6), the CPU 100 checks the state of the main switch 21 again via the signal input circuit 105 (# 210).

If the main switch 21 is not in the "off" state, the CPU 100 checks via the signal input circuit 105 whether the cartridge chamber cover open / close button 22 has been pressed (# 211). If the viewer has not pressed the cartridge chamber lid open / close button 22 or if the lid of the cartridge chamber is not open (# 211), the CPU 100 checks the lighting state of the fluorescent lamps 50 and 51 (# 21).
2). If the fluorescent lamps 50 and 51 are not lit, C
The PU 100 sends a signal to the fluorescent lamp lighting circuit 102 to turn on the fluorescent lamps 50 and 51 (# 213).

The CPU 100 continues to operate the signal input circuit 1
It is checked whether any one of the operation switches has been pressed through the switch 05. When the viewer presses the Up button 24 or the Down button 26 to set the frame number of the film image to be written to the SLM 10 (# 216),
The CPU 100 executes the operation of setting the frame number of the film image to be written to the SLM 10 according to the flow of the "frame number setting" subroutine shown in FIG. 9 (# 223).

In the "frame number setting" subroutine, first, the CPU 100 checks whether or not the film cartridge 35 is loaded in the film cartridge chamber (# 270). As described above, the loaded state of the film cartridge 35 can be detected based on an output signal of a not-shown light emitting / receiving element disposed on the side surface of the film cartridge chamber.

If the film cartridge 35 is not loaded (# 270), the CPU 100 sends a signal to the LCD drive circuit 106, and outputs "OUT" to the liquid crystal display element 27.
Is displayed to warn the viewer that no film is loaded (# 281). After warning that the film cartridge 35 has not been loaded for a while, the process returns to the main routine of FIG. 7 (# 277).

If the film cartridge 35 is loaded (# 270), the CPU 100 checks the value of the flag "Flag2" indicating whether or not the film frame number is being set (# 271). The value of the flag “Flag2” is “0”
If the frame number of the film is not being set (# 27
1) Subsequently, the CPU 100 checks the value of the flag "Flag 1" indicating the state of attachment / detachment of the film cartridge (# 272).

If the value of the flag “Flag 1” is set to “0” and the film cartridge 35 is not attached or detached after the film image is written to the SLM 10 (# 2)
72), the CPU 100 sets EEP to the currently set frame number.
The frame number of the film image written in the SLM 10 stored in the ROM 110 is substituted (# 273). For this reason, the viewer can set the frame number of the film based on the frame number of the film image written in the SLM 10.

On the other hand, if the value of the flag “Flag 1” is “1”
If the film cartridge 35 is detached after the film image is written to the SLM 10 (#
272), the CPU 100 substitutes “0” for the currently set frame number (# 278). Therefore, the viewer can set the frame of the film image to be written to the SLM 10 sequentially from the first frame of the newly loaded film cartridge 35.

Further, the CPU 100 sets the value of the flag "Flag2" indicating whether or not the frame number of the film is being set to the value of "1" for which the frame number is being set (#
274) A signal is sent to the LCD drive circuit 106 to cause the liquid crystal display element 27 to display the frame number being set,
The frame number is displayed during the setting (# 275).

Further, the CPU 100 resets the time T after the viewer sets the frame number of the film to "0", and then starts counting time again (# 276). Then, the process returns to the main routine (# 277).

As described above, even when the liquid crystal display element 27 is not displaying the frame number of the film, the CPU 100 sets the Up button 24 or the Down button to allow the viewer to set the frame number of the film to be written on the SLM 10.
When the button 26 is pressed, the frame number of the film is displayed on the liquid crystal display element 27 immediately. For this reason, the viewer can check the frame number of the currently set film on the liquid crystal display element 27 without operating the display switching button 23.

On the other hand, when the film cartridge 35 is loaded (# 260), the value of the flag "Flag2" indicating whether or not the frame number of the film is being set is "1" and the frame number of the film is being set. If there is (# 271), CPU
100 determines whether the film frame number newly set in response to the operation of the Up button 24 or the Down button 26 is valid for the film frame number displayed on the liquid crystal display element 27 (# 279). . That is,
The CPU 100 determines whether the frame number of the film to be newly set by the viewer does not become larger than the number of photographed frames of the film. Further, the CPU 100 determines whether or not the frame number of the film to be newly set by the viewer does not become smaller than “1”.

If the frame number of the film to be newly set by the viewer is valid (# 279), C
The PU 100 performs addition or subtraction from the frame number of the film being set according to the operation of the Up button 24 or the Down button 26 (# 280).

On the other hand, if the frame number of the film to be newly set by the viewer exceeds the number of frames to be shot or is smaller than "1"(# 279),
The CPU 100 does not change the value of the frame number of the film being set.

The viewer's Up button 24 or Down

Further, the CPU 100 resets the time T after the viewer has set the frame number of the film to "0", and then starts timing again (# 276). Then, the process returns to the main routine of FIG. 7 (# 277).

After returning from the "frame number setting" subroutine, the CPU 100 compares the time T measured after the operation for setting the frame of the film with the preset time T0 (# 204). If the counted time T is shorter than the preset time T0, the CPU 100 continues.
Is a display switching button 23 via the signal input circuit 105.
The display content displayed on the liquid crystal display element 27 selected by the user is confirmed (# 205).

If the display content of the liquid crystal display element 27 is not set to the "time setting mode"(# 205), the CPU 100 further checks the value of the flag "Flag 2" indicating whether or not the frame number of the film is being set. Yes (# 206).

If the viewer is writing the image on the SLM 10 and setting the frame number of the film (# 206), the CPU
100 checks the state of the main switch 21 again via the signal input circuit 105 (# 210).

If the main switch 21 is not in the “off” state, the CPU 10
No. 0 confirms whether or not the cartridge chamber lid open / close button 22 has been pressed via the signal input circuit 105 (# 21).
1). If the viewer has not pressed the cartridge chamber lid open / close button 22 or if the lid of the cartridge chamber has not been opened (# 211), the CPU 100 sets the fluorescent lamp 5
The lighting state of 0, 51 is confirmed (# 212). If the fluorescent lamps 50 and 51 are not lit, the CPU 100 sends a signal to the fluorescent lamp lighting circuit 102 to
Lights 0 and 51 are turned on (# 213).

The CPU 100 continues to operate the signal input circuit 10
It is checked whether any one of the operation switches has been pressed through the terminal 5.

After checking the frame number of the film displayed on the liquid crystal display element 27, the viewer can check the SLM10 of the film image.
When the image writing button 25 is pressed to write data into the image (# 215), the CPU 100 returns to the "image writing" subroutine of FIG. 8 (# 22).

Further, the CPU 100 sets the projection means (the SLM 10 of the film image) to trim the film image via the lens / mirror driving circuit 108.
It is determined whether or not the projection position and the projection magnification setting state have been changed (# 251). If the setting of the projection means has not been changed to perform the trimming of the film image (# 251), the CPU 100 sets the LCD
The display unit 28 of the liquid crystal display element 27 via the drive circuit 106
Delete the trimming display displayed in (# 25)
2). If no trimming display is originally performed on the liquid crystal display element 27, that state is maintained.

Further, the CPU 100 transmits a signal to the film position detecting circuit 107 and the film feeding circuit 103 to cause the film feeding mechanism to feed the film 12 to the liquid crystal display element 2.
The film is fed up to the frame number of the film being set, which is displayed in # 7 (# 253). The frame number of the film indicates the perforation of the film 12 by the light emitting element 16 and the light receiving element 17.
It is determined by optically detecting using CP
Film position detection circuit 107 receiving a signal from U100
The light emitting element such as an infrared light emitting diode emits light to illuminate the end of the film 12, and the light transmitted through the perforation is received by a light receiving element such as a photodiode and the output is detected. CPU 100 is a film position detection circuit 10
The number of the frame is detected from the output of the photodiode detected through the switch 7.

Further, the strobe light emitting circuit 104 receiving the signal from the CPU 100 sets the amount of strobe light emitted by the xenon tube 13 according to the projection magnification of the film image by the projection means. At this time, since the trimming of the film image to be written to the SLM 10 is not performed, the standard strobe light emission amount is set. Further, the SLM drive circuit 101
Sets the driving condition of the SLM 10 to the standard driving condition (# 254). The driving condition of the SLM 10 according to the present embodiment is a pulse width of a voltage applied to the SLM 10 for writing an image (that is, an image storage operation time).

When the strobe light emission amount and the driving condition of the SLM 10 are set (# 254), the CPU 100 continues.
Sends a signal to the SLM drive circuit 101 to erase the image already written in the SLM 10 and
10 is applied with a reset pulse.

Subsequently, the CPU 100 transmits a signal to the strobe light emitting circuit 104 to cause the xenon tube 13 to emit a predetermined amount of light to illuminate the film 12 uniformly. At this time, the projection lens 3 and the three reflecting mirrors 40, 41, 42 constituting the projection means are arranged at standard positions as shown in FIG. The writing light transmitted through the film 12 is reflected by the reflection mirror 40, the projection lens 3, and the reflection mirror 41.
The light is projected onto the SLM 10 via the reflection mirror 42. Further, the CPU 100 transmits a signal to the SLM drive circuit 101 while the xenon tube 13 emits light, and applies a voltage having a predetermined pulse width to the SLM 10. At this time, a predetermined amount of light for obtaining an image with high contrast has reached the SLM 10.

In the SLM 10, the ferroelectric liquid crystal molecules in the area of the photoelectric conversion film 74 irradiated with light are inverted.
The transfer (writing) of the film image is performed (# 25)
5). If the direction of the polarizing plate is set so that the region where the ferroelectric liquid crystal molecules have been inverted by light irradiation is in a non-transmission state, the negative film can be inverted. Also,
The film image written on the SLM 10 can be stored and stored for a long time by the storage function of the ferroelectric liquid crystal 73 constituting a part of the SLM 10.

When the writing of the image on the film 12 to the SLM 10 is completed (# 255), the CPU 100

Further, the CPU 100 sets the value of the flag "Flag 1" indicating the detached state of the film cartridge to "0".
Is set so that the film cartridge 35 including the image written in the SLM 10 is loaded in the cartridge chamber (# 257).

Subsequently, the CPU 100 sends a signal to the fluorescent lamp lighting circuit 102 to turn on the fluorescent lamps 50 and 51 (# 258). A part of the illumination light from the fluorescent lamps 50 and 51 is reflected in the reflection shades 60 and 61 in a cross section parallel to the paper surface.
Is converted into substantially parallel light, and illuminates the SLM 10 uniformly. Further, the illumination light emitted from the SLM 10 is the SLM 1
The angle of view is widened by the transparent substrate 11 having the lens-shaped body disposed in the vicinity of the zero light exit surface. This allows the viewer to view the film image with a wide viewing angle. Since the touch panel 9 is formed of a transparent member, it does not affect the viewing image.

Next, if the projection means is not set to a state in which the trimming display of the film image is performed (# 25)
9), a series of operations for writing the film image to the SLM 10 ends, and the process returns to the main routine of FIG. 7 (# 263). The operation up to this point is the original image display operation described in the claims.

After returning from the "image writing" subroutine, the CPU 100 compares the time T counted after the operation for setting the film frame with the preset time T0 (# 204). If the counted time T is shorter than the preset time T0, the CP
U100 confirms the display content displayed on the liquid crystal display element 27 selected by the display switching button 23 via the signal input circuit 105 (# 205).

If the display content of the liquid crystal display element 27 is not set to the "time setting mode"(# 205), the CPU 100 further checks the value of the flag "Flag 2" indicating whether or not the frame number of the film is being set. Yes (# 206).
If the viewer is setting a film frame number for writing an image on the SLM 10 (# 206), the CPU 100
Again changes the state of the main switch 21 to the signal input circuit 10
5 is confirmed (# 210).

If the main switch 21 is not in the "off" state, the CPU 100 checks via the signal input circuit 105 whether the cartridge chamber cover opening / closing button 22 has been pressed (# 211). If the viewer has not pressed the cartridge chamber lid open / close button 22 or if the lid of the cartridge chamber is not open (# 211), the CPU 100 checks the lighting state of the fluorescent lamps 50 and 51 (# 21).

The PU 100 sends a signal to the fluorescent lamp lighting circuit 102 to turn on the fluorescent lamps 50 and 51 (# 213).

The CPU 100 continues to operate the signal input circuit 10
It is checked whether any one of the operation switches has been pressed through the terminal 5. When the viewer presses the touch pen 2 on the touch panel 9 while checking the film image displayed on the SLM 10 (# 214), the CPU 100 determines that the viewer is going to perform trimming of the displayed image, and FIG. (# 221).

In the "trimming position setting" subroutine, the signal input circuit 105
Is detected on the touch panel 9 (# 29).
0). The viewer can specify two diagonal positions of the place where the trimming is performed while checking the image displayed on the image display device.

The CPU 100 determines the trimming range of the film image from the trimming coordinates detected by the signal input circuit 105 so as to match the aspect ratio of the display screen of the SLM 10 (# 291). At this time, if the aspect ratio of the trimming range specified by the viewer is different from the aspect ratio of the display screen of the SLM 10, the CPU 100 determines the trimming range so that the trimming range specified by the viewer is not missing.

Next, the CPU 100 determines the projection magnification of the trimmed image by the projection means in accordance with the relationship between the determined trimming range and the display screen range of the SLM 10 (for example, so that the two substantially match) (# 292). First, the CPU 100 sends a signal for driving to the lens / mirror driving circuit 108 and moves the projection lens 3 using a lens driving mechanism (not shown). Thus, the film image to be trimmed is further enlarged, and the projection lens 3 is moved to a predetermined position on the film 12 side in the direction of the projection optical axis 4 as shown in FIGS.

Further, the CPU 100 adjusts the position of the reflection mirror 41 to adjust the projection position of the image so that the center position of the image within the determined trimming range coincides with the center position of the display screen of the SLM 10 (see FIG. # 29
2) Adjust the feeding position of the film 12 (# 29)
3).

The position of the image within the trimming range is in the direction parallel to the sheet of FIG. 2 (in the height direction of the screen), and the reflection mirror 41 is slightly inclined (projection light) in the depth direction of the apparatus as shown in FIGS. It is adjusted by moving the film 12 in a non-parallel direction with respect to the axis 4, and the feed position of the film 12 is shifted in a range within a frame of the displayed image in the vertical direction of the paper (the screen width direction in FIG. 1). Will be adjusted by

Specifically, the CPU 100 sets the center position of the trimming range in the direction parallel to the paper surface of FIG.
A drive signal is sent to the lens / mirror drive circuit 108 to drive the reflection mirror driving mechanism (not shown) to move the reflection mirror 41 so as to match the center position of the screen 0.
If the center position of the trimming range input by the viewer is below the standard position in FIG. 2, the reflecting mirror 41 is moved to the reflecting mirror 40 side as shown in FIG. Move.

On the other hand, if the center position of the trimming range input by the viewer is above the standard position in FIG. 2, the reflecting mirror 41 is moved to the opposite side of the reflecting mirror 40 as shown in FIG. To move the film image downward. Note that moving the reflection mirror 41 changes the optical path length of the projection optical system.
The position of the projection lens 3 is also adjusted so that and SLM10 have a conjugate positional relationship.

Further, the CPU 100 controls the film feeding circuit 10 so that the center position of the trimming range in the direction perpendicular to the paper of FIG.
3 to drive the film feeding motor 30 to rotate. The position of the film 12 to be fed is determined by the motor 30.
It is controlled by detecting the slit of the phase plate 30 attached to the rotation shaft of the photodetector 32 by the photointerrupter 32. The operation up to this point is the projection condition setting operation referred to in the claims.

When the projection magnification of the trimmed image is set and the state of the projection optical system and the position of the film 12 are adjusted to set the projection position of the trimmed image, the "image writing" subroutine shown in FIG. And the writing of the trimming image is executed (# 29).
4).

In the "image writing" subroutine, as described above, first, the CPU 100 confirms whether or not the frame number of the film is being set by the viewer (# 24).
0). If the flag “Flag2” indicating whether or not the film frame number is being set is a value of “0” and the viewer has not set the film frame number (# 24)
0), the CPU 100 checks whether or not the film cartridge 35 is loaded in the film cartridge chamber (# 241). If the film cartridge 35 is loaded (# 241), it is checked whether or not the frame number of the film is displayed on the liquid crystal display element 27 (# 24).
2). If the frame number of the film is displayed on the liquid crystal display element 27 (# 242), the CPU 100 sends a signal to the fluorescent lamp lighting circuit 102 to turn off the fluorescent lamps 50 and 51 that are illuminating the SLM 10 with the backlight (# 242). # 2
50).

Further, the CPU 100 sets the projection means (the SLM 10 of the film image) in order to trim the film image via the lens / mirror driving circuit 108.
It is determined whether or not the projection position and the projection magnification setting state have been changed (# 251). here,
Since the setting state of the projection means has been changed, the CPU 10
The strobe light emitting circuit 104 receiving the signal from 0 sets the amount of strobe light emitted by the xenon tube 13 according to the changed projection magnification (# 254). Here, since the projection magnification is changed in the direction of enlargement, the strobe light emission amount is set to be larger than the standard. Furthermore, S
The LM drive circuit 101 changes the drive condition of the SLM 10 from the standard drive condition to a drive condition corresponding to the changed projection magnification. Specifically, the pulse width of the voltage applied for writing the image (that is, the storage operation time) is changed and set so as to increase the amount of light to be written to the SLM 10.

When the strobe light emission amount (writing amount) and the driving conditions of the SLM 10 are set in accordance with the change of the projection magnification, the CPU 100 continues to erase the image already written in the SLM 10 by the SLM driving circuit 101. And a reset pulse is applied to the SLM 10 (# 255).

Further, the CPU 100 transmits a signal to the strobe light emitting circuit 104 to cause the xenon tube 13 to emit light by the amount of light set at # 254, thereby uniformly illuminating the film 12 (# 255). The writing light transmitted through the film 12 is projected on the SLM 10 via the reflection mirror 40, the projection lens 3, the reflection mirror 41, and the reflection mirror 42 as shown in FIG. 3 or FIG.

Further, the CPU 100 transmits a signal to the SLM drive circuit 101 while the xenon tube 13 emits light, and applies a pulse voltage whose pulse width has been changed and set in # 254 to the SLM 10. At this time, a predetermined amount of light for obtaining an image with high contrast has reached the SLM 10.

In the SLM 10, as described above,
The ferroelectric liquid crystal molecules in the region of the photoelectric conversion film 74 irradiated with the light are inverted, and the film image (trimmed image) after trimming is enlarged and transferred. If the direction of the polarizing plate is set so that the region where the ferroelectric liquid crystal molecules have been inverted by light irradiation is in a non-transmission state, the negative film can be inverted. Further, the film image written on the SLM 10 is stored for a long time by the storage action of the ferroelectric liquid crystal 73 constituting a part of the SLM 10 (# 25).
5).

When the writing of the image of the film 12 on the SLM 10 is completed, the CPU 100 stores the frame number of the film image written on the SLM 10 as the frame number in the EEPROM 110 (# 256).

Further, the CPU 100 sets the value of the flag "Flag 1" indicating the state of attachment / detachment of the film cartridge 35 to "0", so that the film cartridge 35 including the image written in the SLM 10 is loaded in the cartridge chamber. It is set (# 257).

Subsequently, the CPU 100 sends a signal to the fluorescent lamp lighting circuit 102 to turn on the fluorescent lamps 50 and 51 (# 258). A part of the illumination light from the fluorescent lamps 50 and 51 is reflected in the reflection shades 60 and 61 in a cross section parallel to the paper surface.
Is converted into substantially parallel light, and illuminates the SLM 10 uniformly. Further, the illumination light emitted from the SLM 10 is the SLM 1
The angle of view is widened by the transparent substrate 11 having the lens-shaped body disposed in the vicinity of the zero light exit surface. In this way, the viewer can view the trimmed image that has been enlarged to the screen size of the SLM 10 and has good quality with a large viewing angle. Up to this point, the trimmed image display operation described in the claims has been described.

Next, if the projection means is set to perform a trimming display of the film image (# 259), C
The PU 100 sends a signal to the LCD drive circuit 106 to display a mark on the display unit 28 of the liquid crystal display element 27 indicating that the trimmed image is displayed on the SLM 10 (#
260). By looking at the display section 28, the viewer can clearly recognize that the trimmed image is displayed on the display screen of the image display device 1.

Next, the CPU 100 sends a signal to the lens / mirror drive circuit 108 to set the photographing lens 3 and the reflection mirror 41 to standard positions using a drive mechanism (not shown) (# 261). This makes it possible to quickly rewrite the image on the SLM 10.

Further, the CPU 100 sends a signal to the film feeding circuit 103 to feed the film 12 so that the frame corresponding to the trimmed image displayed on the SLM 10 returns to the normal position (# 262). Thus, a series of operations for writing the film image to the SLM 10 is completed, and the process returns to the main routine shown in FIG. 7 (# 26).

In this embodiment, when the viewer presses the image write button 25 to write the film image on the SLM 10, the CPU 100 shifts from the main routine to the "image write" subroutine shown in FIG. 11 (# 222).

In the "image writing" subroutine, first, the CPU 100 checks whether or not the frame number of the film is being set by the viewer (# 340). Flag "Flag2" indicating whether or not the film frame number is being set
Is "1", and if the frame number of the film is set by the viewer (# 340), the CPU 10
0 indicates that the viewer confirms the frame number of the film displayed on the liquid crystal display element 27, and
It recognizes that the image writing button 25 has been pressed in order to write data into the SLM 10, and sends a signal to the fluorescent lamp lighting circuit 102 to turn off the fluorescent lamps 50 and 51 illuminating the SLM 10 with backlight (# 350).

Further, the CPU 100 transmits a signal to the film position detecting circuit 107 and the film feeding circuit 103 to cause the film feeding mechanism to feed the film 12 to the liquid crystal display element 2.
The film is fed up to the frame number of the film being set displayed in # 7 (# 351).

Further, the CPU 100 sends a signal to the magnetic write / read circuit 109 to confirm whether the trimming information is recorded in the magnetic recording portion of the film 12 by using the read magnetic head 18 (# 35).
2). If no trimming information has been recorded in the magnetic recording portion of the film 12 (# 352), the strobe light emitting circuit 1
In step 04, the amount of flash light from the xenon tube 13 is set according to the projection magnification via the CPU 100. At this time, SLM
Since the trimming of the film image to be written to 10 is not performed, a standard strobe light emission amount is set. The SLM drive circuit 101 sets the drive conditions of the SLM 10 to standard drive conditions (# 355).

The amount of strobe light (the amount of writing) and S
When the driving conditions of the LM10 spatial light modulator are set (#
355) Subsequently, the CPU 100 transmits a signal to the SLM drive circuit 101 and applies a reset pulse to the SLM 10 in order to erase the image already written in the SLM 10. Further, the CPU 100 transmits a signal to the strobe light emitting circuit 104 to cause the xenon tube 13 to emit a predetermined amount of light to uniformly illuminate the film 12.

At this time, the projection lens 3 and the three reflection mirrors 40, 41, 42 are arranged at standard positions as shown in FIG. The writing light transmitted through the film 12 is projected onto the SLM 10 via the reflection mirror 40, the projection lens 3, the reflection mirror 41, and the reflection mirror 42.

Further, the CPU 100 transmits a signal to the SLM drive circuit 101 while the xenon tube 13 is emitting light, and applies a predetermined pulse voltage to the SLM 10. At this time, a predetermined amount of light for obtaining an image with high contrast has reached the SLM 10.

In the SLM 10, the ferroelectric liquid crystal molecules in the area of the photoelectric conversion film 74 irradiated with light are inverted, and the transfer of the film image is performed. If the direction of the polarizing plate is set so that the region where the ferroelectric liquid crystal molecules have been inverted by light irradiation is in a non-transmission state, the negative film can be inverted. Further, the film image written on the SLM 10 is a ferroelectric liquid crystal 7 that constitutes a part of the SLM 10.
No. 3 is stored for a long time (# 356).

When the writing of the image on the film 12 to the SLM 10 is completed (# 356), the CPU 100
Is the frame number of the film image written in the SLM10.
It is stored as a frame number in the EPROM 110 (# 35)

Further, the CPU 100 sets the value of the flag "Flag 1" indicating the attachment / detachment state of the film cartridge 35 to "0", so that the film cartridge 35 including the image written in the SLM 10 is loaded in the cartridge chamber. It is set (# 358).

Subsequently, the CPU 100 sends a signal to the fluorescent lamp lighting circuit 102 to turn on the fluorescent lamps 50 and 51 (# 359). A part of the illumination light from the fluorescent lamps 50 and 51 is reflected in the reflection shades 60 and 61 in a cross section parallel to the paper surface.
Is converted into substantially parallel light, and illuminates the SLM 10 uniformly. Further, the illumination light emitted from the SLM 10 is the SLM 1
The angle of view is widened by the transparent substrate 11 having a lens-shaped body disposed in the vicinity of the light-emitting surface 0, so that the viewer can view the subject image photographed on the film 12 by a camera or the like. Since the touch panel 9 is formed of a transparent member, it does not affect the viewing image.

At this time, if the setting state of the projection means (the setting state of the projection position and the projection magnification of the film image with respect to the SLM 10) is not set to the state of performing the trimming display of the film image (# 360), the CPU 100 sets the L
The trimming display displayed on the display section 28 of the liquid crystal display element 27 via the CD drive circuit 106 is deleted (# 3).
65). If no trimming display is originally performed on the liquid crystal display element 27, that state is maintained.

When a series of operations for writing a film image to the SLM 10 is completed, the process returns to the main routine shown in FIG. 7 (# 364).

Subsequently, when the viewer presses the touch pen 2 on the touch panel 9 while checking the film image enlarged and displayed on the SLM 10, the CPU 100 determines that the viewer is going to trim the displayed image. The process proceeds to the "trimming position setting" subroutine shown in FIG. 12 (# 221).

The signal input circuit 105 detects the coordinates of the position where the viewer has pressed the touch pen 2 against the touch panel 9 (# 390). The viewer can check the image displayed on the SLM 10 while viewing the diagonal position 2 of the place where the trimming is performed.
You just need to point. The CPU 100 is a signal input circuit 1
From the trimming coordinates detected in 05, the trimming range of the film image is determined so as to match the aspect ratio of the display screen of the SLM 10 (# 391). At this time, the aspect ratio of the trimming range specified by the viewer is SLM1.
0 is different from the display screen aspect ratio,
0 determines the trimming range so that the trimming range specified by the viewer is not missing.

Further, the CPU 100 sends a signal to the magnetic writing / reading circuit 109 to store the trimming position information in the magnetic recording portion of the film 12 using the writing magnetic head 19 (# 392). This is the information writing operation described in the claims.

After writing the trimming position information on the film 12 in this way, in order to execute writing of the trimmed image on the SLM 10, the "image writing" shown in FIG.
The process proceeds to a subroutine (# 393).

In the "image writing" subroutine, first, the CPU 100 checks whether or not the frame number of the film is being set by the viewer (# 340).

If the flag "Flag2" indicating whether or not the frame number of the film is being set is "0" and the frame number of the film is not set by the viewer (# 340), the CPU 100 Is the film cartridge 3
It is confirmed whether or not No. 5 is loaded in the film cartridge chamber of the image display device 1 (# 341). If the film cartridge 35 is loaded (# 341), it is checked whether or not the frame number of the film is displayed on the liquid crystal display element 27 (# 342). If the frame number of the film is displayed on the liquid crystal display element 27 (# 342), the CPU
100 sends a signal to the fluorescent lamp lighting circuit 102 to
A fluorescent lamp 50 for backlighting the LM 10;
The light 51 is turned off (# 350).

Further, the CPU 100 sends a signal to the magnetic writing / reading circuit 109 to confirm whether the trimming information is recorded on the magnetic recording portion of the film 12 using the reading magnetic head 18 (# 352).
If trimming information is recorded in the magnetic recording section of the film 12, the state of the projection means is set based on the information.

First, the CPU 100 determines the projection magnification of the trimmed image by the projection means in accordance with the relationship between the determined trimming range and the display screen range of the SLM 10 (for example, so that the two substantially match) (# 353). ). First, the CPU 100 sends a signal for driving to the lens / mirror driving circuit 108 and moves the projection lens 3 using a lens driving mechanism (not shown). Thus, the film image to be trimmed is further enlarged, and the projection lens 3 is moved to a predetermined position on the film 12 side in the direction of the projection optical axis 4 as shown in FIGS.

Further, the CPU 100 adjusts the position of the reflection mirror 41 to adjust the projection position of the image so that the center position of the image within the determined trimming range matches the center position of the display screen of the SLM 10 ( # 35
3) Adjust the feeding position of the film 12 (# 35)
4).

The position of the image within the trimming range is the position in the direction parallel to the plane of the drawing (the height direction of the screen) in FIG. 2, and the reflection mirror 41 is slightly oblique to the depth direction of the apparatus as shown in FIGS. It is adjusted by moving the film 12 in a non-parallel direction with respect to the axis 4, and the feed position of the film 12 is shifted in a range within a frame of the displayed image in the vertical direction of the paper (the screen width direction in FIG. 1). Will be adjusted by

Specifically, the CPU 100 sets the center position of the trimming range in the direction parallel to the paper of FIG.
A drive signal is sent to the lens / mirror drive circuit 108 to drive the reflection mirror driving mechanism (not shown) to move the reflection mirror 41 so as to match the center position of the screen 0.
If the center position of the trimming range input by the viewer is below the standard position in FIG. 2, the reflecting mirror 41 is moved to the reflecting mirror 40 side as shown in FIG. Move.

On the other hand, if the center position of the trimming range input by the viewer is above the standard position in FIG. 2, the reflection mirror 41 is moved to the opposite side of the reflection mirror 40 as shown in FIG. To move the film image downward. Note that moving the reflection mirror 41 changes the optical path length of the projection optical system.
The position of the projection lens 3 is also adjusted so that and SLM10 have a conjugate positional relationship.

Further, the CPU 100 controls the film feeding circuit 10 so that the center position of the trimming range in the direction perpendicular to the paper of FIG.
3 to drive the film feeding motor 30 to rotate. The position of the film 12 to be fed is determined by the motor 30.
It is controlled by detecting the slit of the phase plate 30 attached to the rotation shaft of the photodetector 32 by the photointerrupter 32. The operation up to this point is the projection condition setting operation referred to in the claims.

When the projection magnification of the trimmed image is set as described above and the state of the projection optical system and the position of the film 12 are adjusted to set the projection position of the trimmed image, the strobe light emitting circuit receiving the signal from the CPU 100 Reference numeral 104 sets the amount of flash light emission according to the determined projection magnification. At this time, since the projection magnification has been changed from the standard direction to the enlarged direction, the strobe light emission amount is set to be large. Further, the SLM drive circuit 1
01 sets the drive conditions of the SLM 10 from the standard drive conditions to the drive conditions corresponding to the changed projection magnification (# 3).
55). Specifically, the pulse width of the voltage applied for writing the image (that is, the storage operation time) is changed and set so as to increase the amount of light to be written to the SLM 10.

When the strobe light emission amount (writing amount) and the driving conditions of the SLM 10 are changed and set in accordance with the change in the projection magnification, the CPU 100 continues to erase the image already written in the SLM 10 by the SLM driving circuit 101. And a reset pulse is applied to the SLM 10 (# 356).

Further, the CPU 100 transmits a signal to the strobe light emitting circuit 104 to cause the xenon tube 13 to emit light by the amount of light set at # 355, thereby uniformly illuminating the film 12 (# 356). As shown in FIG. 3 or FIG. 4, the writing light transmitted through the film 12 is projected on the SLM 10 via the reflection mirror 40, the projection lens 3, the reflection mirror 41, and the reflection mirror 42.

Further, the CPU 100 transmits a signal to the SLM drive circuit 101 while the xenon tube 13 emits light, and applies a pulse voltage whose pulse width is changed and set in # 355 to the SLM 10. At this time, a predetermined amount of light for obtaining an image with high contrast has reached the SLM 10.

In the SLM 10, the ferroelectric liquid crystal molecules in the region of the photoelectric conversion film 74 irradiated with light are inverted.
The transfer of the film image is performed. If the direction of the polarizing plate is set so that the region where the ferroelectric liquid crystal molecules have been inverted by light irradiation is in a non-transmission state, the negative film can be inverted. Further, the film image written on the SLM 10 is stored for a long time by the storage action of the ferroelectric liquid crystal 73 constituting a part of the SLM 10.

When the writing of the image of the film 12 on the SLM 10 is completed, the CPU 100 stores the frame number of the film image written on the SLM 10 as the frame number in the EEPROM 110 (# 357).

Further, the CPU 100 sets the value of the flag "Flag 1" representing the state of attachment / detachment of the film cartridge 35 to "0", so that the film cartridge 35 containing the image written in the SLM 10 is loaded in the cartridge chamber. (# 358).

Subsequently, the CPU 100 sends a signal to the fluorescent lamp lighting circuit 102 to turn on the fluorescent lamps 50 and 51 (# 359). A part of the illumination light from the fluorescent lamps 50 and 51 is reflected in the reflection shades 60 and 61 in a cross section parallel to the paper surface.
Is converted into substantially parallel light, and illuminates the SLM 10 uniformly. Further, the illumination light emitted from the SLM 10 is the SLM 1
The angle of view is widened by the transparent substrate 11 having the lens-shaped body disposed in the vicinity of the zero light exit surface. In this way, the viewer can view the trimmed image that has been enlarged to the screen size of the SLM 10 and has good quality with a large viewing angle.

Further, if the projection means is set to perform a trimming display of the film image (# 360),
The CPU 100 sends a signal to the LCD drive circuit 106 to display a mark on the display unit 28 of the liquid crystal display element 27 indicating that the trimmed image is displayed on the SLM 10 (# 361). By watching the trimming display, the viewer can clearly recognize that the trimmed image is displayed on the SLM 10.

Next, the CPU 100 sends a signal to the lens / mirror drive circuit 108 to set the photographing lens 3 and the reflection mirror 41 to standard positions using a drive mechanism (not shown) (# 362). This makes it possible to quickly rewrite the next image.

Further, the CPU 100 sends a signal to the film feeding circuit 103 to send the film 12 to the SLM 10.
Are fed so that the frame corresponding to the trimming image displayed in (2) returns to the normal position (# 363). Thus, a series of operations for writing the film image to the SLM 10 is completed, and the process returns to the main routine shown in FIG. 7 (# 36).

In the present embodiment, the trimming information input using the touch pen 2 and the touch panel 9 provided on the image display device 1 is recorded on the magnetic recording section of the film 12, and the information is read to read the trimming information. Although the case where the trimming display is executed has been described, according to the present embodiment, other devices (for example, a camera,
The trimming information input by a film scanner may be read out through the reading head 18 to perform trimming display of the film image.

Further, in the present embodiment, the input trimming position information is written to the magnetic recording portion of the film 12, so that, for example, the trimming information different from the trimming information originally recorded in the magnetic recording portion of the film 12 is used. Is newly set, it is also possible to rewrite the original trimming information with new trimming information.

(Third Embodiment) FIGS. 13 and 14 show the structure of an image display device according to a third embodiment of the present invention.

The image display device of this embodiment is different from the image display devices of the first and second embodiments in that a liquid crystal display element (trimming frame display means) 8 for displaying a trimming frame 7 on an image display section is provided. It is provided. The touch panel 9 is mounted on the surface of the liquid crystal display element 8. Other configurations are the same as those of the image display devices of the first and second embodiments. Therefore, the same components as those of the embodiments are denoted by the same reference numerals and description thereof will be omitted.

FIG. 15 shows a main routine for controlling the operation of the image display device of this embodiment. First, the CPU 100 checks whether or not the film cartridge chamber cover opening / closing button 22 is pressed via the signal input / output circuit 105 to open the film cartridge chamber cover (# 401). When the viewer presses the film cartridge chamber cover open / close button 22 in order to newly load the film 12 to be viewed on the image display device 1, the CPU 100 sets a flag indicating whether or not the film cartridge 35 has been attached / detached. “Flag1” is set to “1” (# 424). Here, the flag “Flag1”
When the value is "0", it indicates that the film cartridge 35 is not attached or detached, and when the value is "1", it indicates that the film cartridge 35 is attached or detached.

Further, the CPU 100 waits until the viewer switches the main switch 21 from "off" to "on"(# 402).

The main switch 21 is set to "o" by the viewer.
ff ”to“ on ”(# 402), the CP
U100 detects the state via the signal input circuit 105 and sends a signal to the fluorescent lamp lighting circuit 102 to light the fluorescent lamps 50 and 51 (# 403).

When the fluorescent lamps 50 and 51 are turned on, the SLM 1
When the backlight is illuminated with 0, the CPU 100 determines the time T counted after the operation for setting the frame of the film.
Is compared with a preset time T0 (# 404).
If the counted time T is shorter than the preset time T0, the CPU 100 subsequently confirms the display content displayed on the liquid crystal display element 27 selected by the display switching button 23 via the signal input circuit 105 ( # 40
5).

If the display content of the liquid crystal display element 27 is not set to the "time setting mode"(# 405), the CPU 100 further checks the value of the flag "Flag 2" indicating whether or not the frame number of the film is being set. (# 406).
When the value of the flag “Flag2” is “0”, it indicates that the frame number of the film image to which the viewer writes the image is not being set, and when the value is “1”, the viewer can change the frame number of the film image. Indicates that setting is in progress.

If the viewer is not setting the image frame number of the film to be written to the SLM 10 (# 406), the CPU 1
00 confirms the display mode of the liquid crystal display element 27 again (# 407). If the display mode of the liquid crystal display element 27 is "time display mode", the CPU 100 sends a signal to the LCD drive circuit 106 to display the time on the liquid crystal display element 27 (# 426).

On the other hand, if the display mode of the liquid crystal display element 27 is "frame number display mode"(# 408), C
The PU 100 sends a signal to the LCD drive circuit 106 to display the frame number on the liquid crystal display element 27 (# 409). At this time, the frame number displayed on the liquid crystal display element 27 is SLM.
10 is the frame number of the film image written in 10.

The frame number of the film image written in the SLM 10 is stored in the EEPROM 110.

If the display mode of the liquid crystal display element 27 is "non-display mode"(# 408), the CPU
100 sends a signal to the LCD drive circuit 106 to prevent the liquid crystal display element 27 from displaying (# 418).

When the mode check is completed in this way, the CPU
100 checks the state of the main switch 21 again via the signal input circuit 105 (# 410).

If the main switch 21 is not in the "off" state, the CPU 100 checks via the signal input circuit 105 whether the cartridge chamber cover open / close button 22 has been pressed (# 411).

If the viewer presses the cartridge chamber cover open / close button 22 to change the film to be viewed (#
411), the cartridge chamber lid is opened by a cartridge chamber lid opening / closing mechanism (not shown), and a flag “Flag 1” indicating a film cartridge attaching / detaching state assuming that the viewer has replaced the film cartridge 35 is assumed.
Is set to "1"(# 419). At this time, CPU1
00 sends a signal to the fluorescent lamp lighting circuit 102 to
The fluorescent lamps 50 and 51, which illuminated 10 from behind, are turned off.

On the other hand, if the viewer has not pressed the cartridge chamber lid open / close button 22 or the cartridge chamber lid has not been opened (# 411), the CPU 100 checks the lighting state of the fluorescent lamps 50 and 51 (# 41
2). If the fluorescent lamps 50 and 51 are not lit, C
The PU 100 sends a signal to the fluorescent lamp lighting circuit 102 to turn on the fluorescent lamps 50 and 51 (# 413). As described above, the lighting state of the fluorescent lamps 50 and 51 is controlled by the open / close state of the lid of the film cartridge chamber. Therefore, if the main switch 21 is in a state other than “off” and the fluorescent lamp 5 is in the off state, the viewer can use It can be recognized that the lid of the cartridge chamber remains open.

Subsequently, the CPU 100 sets the signal input circuit 1
It is checked whether any one of the operation switches has been pressed through the switch 05. After confirming the frame number of the film displayed on the liquid crystal display element 27, the viewer can check the SLM1 of the film image.
When the image write button 25 is pressed to write 0 (# 415), the process proceeds to the "image write" subroutine shown in FIG. 16 to write a film image (# 422).

In the "image writing" subroutine, first, the CPU 100 checks whether or not the frame number of the film is being set by the viewer (# 440).

If the flag "Flag2" indicating whether or not the frame number of the film is being set is "0" and the frame number of the film has not been set by the viewer,
The CPU 100 checks whether the film cartridge 35 is loaded in the film cartridge chamber (#
441). A film cartridge 35 is attached to the image display device 1.
Is loaded, it is confirmed whether or not the frame number of the film is displayed on the liquid crystal display element 27 (# 44).
2). If the frame number of the film is displayed on the liquid crystal display element 27, the CPU 100 checks whether or not the trimming frame 7 is being displayed on the liquid crystal display element 8 via the LCD drive circuit 106 (# 450). If the viewer has not input the trimming position of the film image, the CPU 100 sends a signal to the film position detecting circuit 107 and the film feeding circuit 103 to transfer the film 12 to the liquid crystal display element 27 by the film feeding mechanism. The film is fed up to the displayed frame number of the film being set (# 45).

Further, the CPU 100 sends a signal to the magnetic writing / reading circuit 109 to confirm whether the trimming information is recorded on the magnetic recording portion of the film 12 by using the reading magnetic head 18 (# 452).
If the trimming information is recorded on the magnetic recording portion of the film 12, the CPU 100 sends a signal to the LCD drive circuit 106 to display the trimming frame 7 corresponding to the recorded trimming information on the liquid crystal display element 8 (# 45
5).

Further, the CPU 100 starts a timer to display the trimming frame 7 on the liquid crystal display element 8 for a predetermined time (# 456). If the viewer instructs to write an image while the trimming frame 7 is displayed on the liquid crystal display element 8, the trimming image is written. When the trimming position of the film image is set,
The process returns to the main routine of FIG. 15 (# 469).

On the other hand, if no trimming information is recorded in the magnetic recording portion of the film 12 (# 452),
100 sends a signal to the fluorescent lamp lighting circuit 102 to set the SL
Fluorescent lamps 50 and 5 illuminating M10 with backlight
1 is turned off (# 453). Further, the CPU 100
The trimming display displayed on the display unit 28 of the liquid crystal display element 27 via the LCD drive circuit 106 is erased (# 454). If no trimming display is originally performed on the liquid crystal display element 27, that state is maintained.

Subsequently, the strobe light emitting circuit 104 receiving the signal from the CPU 100 sets the amount of strobe light emission of the xenon tube 13 according to the projection magnification of the film image by the projection means. Here, since the trimming of the film image to be written to the SLM 10 is not performed, the standard strobe light emission amount is set. Further, the SLM drive circuit 101
Sets the driving conditions of the SLM 10 to the standard driving conditions (# 461). The driving condition of the SLM 10 according to the present embodiment is a pulse width of a voltage applied to the SLM 10 for writing an image (that is, an image storage operation time).

When the strobe emission light amount (writing light amount) and the driving conditions of the SLM 10 are set in this way, the CPU 100 continuously sends a signal to the SLM driving circuit 101 to erase the image already written in the SLM 10 by erasing the image. To the reset pulse (# 46)

Further, the CPU 100 transmits a signal to the strobe light emitting circuit 104 to cause the xenon tube 13 to emit a predetermined amount of light to uniformly illuminate the film 12 (# 462). At this time, in the projection means for projecting the image of the film 12 on the SLM 10, the projection lens 3 and the three reflection mirrors 40, 41, 42 are arranged at standard positions as shown in FIG. The writing light transmitted through the film 12 is projected onto the SLM 10 via the reflection mirror 40, the projection lens 3, the reflection mirror 41, and the reflection mirror 42.

Further, the CPU 100 transmits a signal to the SLM drive circuit 101 while the xenon tube 13 emits light, and applies a predetermined pulse voltage to the SLM 10 (# 462). At this time, a predetermined amount of light for obtaining an image with high contrast has reached the SLM 10.

In the SLM 10, the ferroelectric liquid crystal molecules in the region of the photoelectric conversion film 74 irradiated with light are inverted.
The transfer of the film image is performed. If the direction of the polarizing plate is set so that the region where the ferroelectric liquid crystal molecules have been inverted by light irradiation is in a non-transmission state, the negative film can be inverted. Further, the film image written on the SLM 10 is stored for a long time by the storage action of the ferroelectric liquid crystal 73 constituting a part of the SLM 10.

When the writing of the image on the film 12 to the SLM 10 is completed, the CPU 100 sets the SLM 10
The frame number of the film image written in the
10 is stored as a frame number (# 463).

Further, the CPU 100 sets the value of the flag "Flag 1" indicating the detached state of the film cartridge to "0", and sets the film cartridge 35 containing the image written in the SLM 10 so as to be loaded in the cartridge chamber. (# 464).

Subsequently, the CPU 100 sends a signal to the fluorescent lamp lighting circuit 102 to turn on the fluorescent lamps 50 and 51 (# 465). Part of the illumination light from the fluorescent lamps 50 and 51 is reflected in the reflection shades 60 and 6 in a section parallel to the plane of the drawing.
The light is converted into substantially parallel light by 1 and illuminates the SLM 10 uniformly.

The illumination light emitted from the SLM 10 is transmitted to the SLM 1
The angle of view is widened by the transparent substrate 11 having the lens-shaped body disposed in the vicinity of the zero light exit surface. This allows the viewer to view the film image at a wide angle of view. Since the liquid crystal display element 8 with the touch panel is set to the non-display state (transparent state), it does not affect the viewing image. The operation up to this point is the original image display operation described in the claims.

At this time, if the projection means is not set to the state in which the trimming display of the film image is performed (# 46)
6), a series of operations for writing the film image to the SLM 10 is completed, and the process returns to the main routine of FIG. 15 (# 469).

Upon returning from the "image writing" subroutine, the CPU 100 sets the time T measured after the operation for setting the film frame and the time T0 set in advance.
And (# 404). When the counted time T is shorter than the preset time T0, the CPU 100 checks the display content displayed on the liquid crystal display element 27 selected by the display switching button 23 via the signal input circuit 105 ( # 405).

If the display content of liquid crystal display element 27 is not set to the "time setting mode"(# 405), CPU 100 further checks the value of flag "Flag 2" indicating whether or not the frame number of the film is being set. (# 406).

If the viewer is setting the frame number of the film to write an image on the SLM 10 (# 406), the CPU 100 as the control means checks the state of the main switch 21 again via the signal input circuit 105. (# 41
0).

If the main switch 21 is not in the “off” state, the CPU 10
No. 0 confirms whether the cartridge chamber cover open / close button 22 has been pressed via the signal input circuit 105 (# 41).
1). If the viewer has not pressed the cartridge chamber lid opening / closing button 22 or if the cartridge chamber lid has not been opened (# 411), the CPU 100 sets the fluorescent lamp 5
The lighting state of 0 and 51 is confirmed (# 412). If the fluorescent lamps 50 and 51 are not lit, the CPU 100 sends a signal to the fluorescent lamp lighting circuit 102 to
0 and 51 are turned on (# 413).

Subsequently, the CPU 100 sets the signal input circuit 1
It is checked whether any one of the operation switches has been pressed through the switch 05. If the viewer inputs the trimming position using the touch panel 9 while observing the image displayed on the image display device 1 (# 414), the CPU 100 determines that the viewer is going to trim the displayed image. Then, the process proceeds to the "trimming position setting" subroutine shown in FIG. 17 (# 421).

In the "trimming position setting" subroutine, first, the signal input circuit 105
Is detected on the touch panel 9 (# 49).
0). The viewer may indicate two diagonal positions of the place where the trimming is performed while checking the image displayed on the SLM 10. The CPU 100 determines the trimming range of the film image from the trimming coordinates detected by the signal input circuit 105 so as to match the aspect ratio of the display screen of the SLM 10 (# 491). At this time, if the aspect ratio of the trimming range specified by the viewer is different from the aspect ratio of the display screen of the SLM 10, the CPU 100 determines the trimming range so that the trimming range specified by the viewer is not missing.

Further, the CPU 100 controls the LCD drive circuit 1
A signal is sent to the LCD device 06 to display the determined trimming frame 7 on the liquid crystal display element 8 (# 492). Also, CPU
100 starts a timer to display the trimming frame 7 on the liquid crystal display element 8 for a predetermined time (# 49).
3). After the viewer determines the trimming range of the film, the liquid crystal display element 8 displays a trimming frame 7 for a predetermined time.
Is displayed, the viewer can check whether the input trimming position is appropriate.

If an image writing is instructed while the trimming frame 7 is displayed on the liquid crystal display element 8, the writing of the trimmed image is executed. When the trimming position of the film image is set, the process returns to the main routine of FIG. 15 (# 494).

Upon returning from the "trimming position setting" subroutine to the main routine, the CPU 100 compares the time T measured after the operation for setting the film frame with the preset time T0 (# 404). If the counted time T is shorter than the preset time T0, the CPU 100 subsequently confirms the display content displayed on the liquid crystal display element 27 selected by the display switching button 23 via the signal input circuit 105 ( # 40
5).

If the display content of the liquid crystal display element 27 is not set to the "time setting mode"(# 405), the CPU
100 checks the value of the flag "Flag2" indicating whether or not the frame number of the film is being set (# 406).

If the viewer is setting the frame number of the film image for writing the image on the SLM 10, (# 4
06), the CPU 100 confirms again the state of the main switch 21 via the signal input circuit 105 (# 41)
0).

If the main switch 21 is not in the "off" state, the CPU 100 checks via the signal input circuit 105 whether or not the cartridge chamber cover open / close button 22 has been pressed (# 411). If the viewer has not pressed the cartridge chamber lid opening / closing button 22 or the cartridge chamber lid is not open (# 411), the CPU 100 checks the lighting state of the fluorescent lamps 50 and 51 (# 41).
2). If the fluorescent lamps 50 and 51 are not lit, C
The PU 100 sends a signal to the fluorescent lamp lighting circuit 102 to turn on the fluorescent lamps 50 and 51 (# 413).

Subsequently, the CPU 100 sets the signal input circuit 1
It is checked whether any one of the operation switches has been pressed through the switch 05. The viewer checks the frame number of the film displayed on the liquid crystal display element 27, and checks the SLM of the film image.
When the image write button 25 is pressed to write data into the image 10 (# 415), the CPU 100 proceeds to an "image write" subroutine to write a film image (# 422).

In the “image writing” subroutine, the CP
U100 confirms whether or not the frame number of the film is being set by the viewer (# 440). If the flag "Flag2" indicating whether or not the frame number of the film is being set is "0" and the viewer has not set the frame number (# 440), the CPU 10
No. 0 confirms whether the film cartridge 35 is loaded in the film cartridge chamber of the image display device 1 (# 441).

If the film cartridge 35 is loaded (# 441), it is checked whether or not the frame number of the film is displayed on the liquid crystal display element 27 (# 442).
If the frame number of the film is displayed on the liquid crystal display element 27 (# 442), the CPU 100 sets the LCD drive circuit to 10
It is confirmed whether or not the trimming frame 7 is being displayed on the liquid crystal display element 8 via the display 6 (# 450). If the viewer has pressed the image writing button 25 immediately after inputting the trimming position, the CPU 100 sets the fluorescent lamp lighting circuit 1
02, the fluorescent lamps 50 and 51 illuminating the SLM 10 with backlight are turned off (# 457).

Next, the CPU 100 determines the projection magnification of the trimmed image by the projection means in accordance with the relationship between the determined trimming range and the display screen range of the SLM 10 (for example, so that the two substantially match) (# 458). First, the CPU 100 sends a signal for driving to the lens / mirror driving circuit 108 and moves the projection lens 3 using a lens driving mechanism (not shown). Thereby, the film image to be trimmed is further enlarged, and the projection lens 3 is moved to a predetermined position on the film 12 side in the direction of the projection optical axis 4 (see FIGS. 3 and 4).

Further, the CPU 100 adjusts the position of the reflection mirror 41 to adjust the projection position of the image so that the center position of the image within the determined trimming range coincides with the center position of the display screen of the SLM 10 ( # 45
8) Adjust the feeding position of the film 12 (# 45)
9).

The position of the image within the trimming range is shown in FIG.
Is adjusted by moving the reflection mirror 41 slightly obliquely (non-parallel to the projection optical axis 4) in the depth direction of the apparatus, and is adjusted in the direction perpendicular to the paper (in FIG. 14). (Screen width direction) is adjusted by shifting the feeding position of the film 12 within the range of the frame of the displayed image.

Specifically, the CPU 100 sets the center position of the trimming range in the direction parallel to the paper of FIG.
A drive signal is sent to the lens / mirror drive circuit 108 to drive the reflection mirror driving mechanism (not shown) to move the reflection mirror 41 so as to match the center position of the screen 10. If the center position of the trimming range input by the viewer is below the standard position (center position),
The reflection mirror 41 is moved to the reflection mirror 40 side to move the film image upward.

On the other hand, if the center position of the trimming range input by the viewer is above the standard position (the center position), the reflecting mirror 41 is moved to the opposite side of the reflecting mirror 40 to make the film image. To the bottom. Note that moving the reflection mirror 41 changes the optical path length of the projection optical system, but also adjusts the position of the projection lens 3 so that the film 12 and the SLM 10 have a conjugate positional relationship.

In addition, the CPU 100 controls the film feeding circuit 1 so that the center position of the trimming range in the direction perpendicular to the paper of FIG.
A driving signal is sent to the motor 03 to rotate the film feeding motor 30. The position of the film 12 to be fed is determined by the motor 3
The control is performed by detecting the slit of the phase plate 30 attached to the 0 rotation axis by the photo interrupter 32. The operation up to this point is the projection condition setting operation referred to in the claims.

When the state of the projection means is changed and the position of the film 12 is adjusted in this way, the CPU 100
A signal is sent to the drive circuit 106 to display a mark on the display unit 28 of the liquid crystal display element 27 indicating that the trimmed image is displayed on the SLM 10 (# 460).

Further, the strobe light emitting circuit 104 which has received the signal from the CPU 100 sets the amount of strobe light emission according to the projection magnification determined in # 458. At this time, since the projection magnification has been changed in a direction in which the projection magnification is larger than the standard, the strobe light emission amount is set to be large (# 461). Further, the SLM drive circuit 101
The drive condition of M10 is set so that the pulse width of the voltage applied to SLM10 is increased according to the projection magnification so that the amount of writing to SLM10 is increased (# 461).

The amount of strobe light (the amount of writing) and S
When the drive conditions of the LM 10 are set (# 461), the CPU 100 subsequently transmits a signal to the SLM drive circuit 101 and applies a reset pulse to the SLM 10 in order to erase the image already written in the SLM 10.

Further, the CPU 100 transmits a signal to the strobe light emitting circuit 104 to cause the xenon tube 13 to emit light by the light emission amount determined in # 461, thereby uniformly illuminating the film 12.

The writing light transmitted through the film 12 is projected on the SLM 10 via the reflection mirror 40, the projection lens 3, the reflection mirror 41 and the reflection mirror 42.

Further, the CPU 100 transmits a signal to the SLM driving circuit 101 while the xenon tube 13 emits light, and changes the voltage of the pulse width determined in # 461 to the SLM1.
Apply to 0. At this time, a predetermined amount of light for obtaining an image with high contrast has reached the SLM 10.

In the SLM 10, the ferroelectric liquid crystal molecules in the region of the photoelectric conversion film 74 irradiated with light are inverted,
The transfer of the film image is performed. If the direction of the polarizing plate is set so that the region where the ferroelectric liquid crystal molecules have been inverted by light irradiation is in a non-transmission state, the negative film can be inverted. Further, the film image written on the SLM 10 is stored for a long time by the storage action of the ferroelectric liquid crystal 73 constituting a part of the SLM 10 (# 462).

When the writing of the trimmed image on the film 12 to the SLM 10 is completed (# 462), C
The PU 100 stores the frame number of the film image written in the SLM 10 as the frame number in the EEPROM 110 (# 463).

Further, the CPU 100 sets the value of the flag "Flag 1" representing the film cartridge attachment / detachment state to "0".
Is set so that the film cartridge 35 including the image written in the SLM 10 is loaded in the cartridge chamber (# 464).

Subsequently, the CPU 100 sends a signal to the fluorescent lamp lighting circuit 102 to turn on the fluorescent lamps 50 and 51 (# 465). A part of the illumination light from the fluorescent lamps 50 and 51 is reflected in the reflection shades 60 and 61 in a cross section parallel to the paper surface.
Is converted into substantially parallel light, and illuminates the SLM 10 uniformly. The angle of view of the illumination light emitted from the SLM 10 is widened by the transparent substrate 11 having a lens-shaped body disposed near the light emission surface of the SLM 10. At this time, the trimming frame 7 of the liquid crystal display element 8 with the touch panel is erased, so that the viewing image is not affected. Thereby, the viewer can view the trimmed image having the good screen quality enlarged to the screen size of the SLM 10 with a large viewing angle.

At this time, since the projection means is set to a state in which trimming display of the film image is performed (# 46).
6), the CPU 100 sends a signal to the lens / mirror drive circuit 108, and sets the photographing lens 3 and the reflection mirror 41 to standard positions using a drive mechanism (not shown) (# 46).
7). This makes it possible to quickly rewrite the next image.

Further, the CPU 100 sends a signal to the film feeding circuit 103 to feed the film 12 such that the frame corresponding to the trimmed image displayed on the SLM 10 returns to the normal position (# 468). Thus, a series of operations for writing the film image to the SLM 10 is completed, and the process returns to the main routine shown in FIG. 15 (# 46).
9).
