DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film image input device and a film transport device, and more particularly to a film image input device and a film transport device for obtaining the flatness of a film in an image capturing area of a still photo film.

[0002]

2. Description of the Related Art Conventionally, a film image input device for reproducing an image of a developed still photo film on a video monitor is disclosed in US Pat. Nos. 4,482,924, 4,485,406 and 4,506,300.
, WO90 / 04301 and the like. For example, FIG.
As shown in FIG. 5, a film image input device 36 includes a film feeding system including a supply reel 38 and a take-up reel 40 for feeding a long developed still photographic film 37,
It comprises an illumination unit 41A, an imaging optical system 41 composed of a photographing lens 41B, an image sensor 48A such as a CCD, and an image signal processing circuit 48B.

The film 37 is sent one frame at a time between the illumination unit 41A and the taking lens 41B. The image of the film 37 is illuminated by the illumination light from the illumination unit 41A, and the illuminated image is taken by the photographing lens 41B.
And an image is formed on the image sensor 48A. As a result, the image on the film 37 is transferred to the image sensor 48A.
After being converted into an image signal, the signal is processed by the image signal processing circuit 48B, and then output to the video monitor 49 as a video signal, and reproduced on the video monitor 49. Some film image input devices of this type include a zoom mechanism, a film scanning mechanism (XY moving mechanism), an image sensor rotating mechanism, and the like.

[0004]

By the way, the above-mentioned conventional film image input apparatus uses a developed photographic film 3.
7 is supplied directly to the supply reel 38 and the take-up reel 40 in the apparatus.
Since the film is fed after the film is wound, the handling of the photographic film 37 is complicated, and the film 37 may be damaged or stained.

For example, as shown in FIG. 61, when a supply reel 38 in which a photographic film 37 is wound is used, the supply reel 38 is loaded into a film loading section 39,
One end of the outermost film is manually stretched and wound around the take-up reel 40 through the imaging optical system 41, and the image surface of the film 37 is taken out of the imaging optical system 4.
The reproduction preparation is completed only after the focal plane is set to one focal plane. Also, when the reproduction of the entire screen is completed and the film is to be taken out, a switch for winding the film around the supply reel 38 while manually extending one end of the outermost periphery of the film wound around the take-up reel 40, and rewinding the film. Press to rewind. Then, after the rewinding of the entire length of the film is completed, the stop button is pressed to take out the supply reel 38 from the film loading unit 39. The above complicated work is required.

Japanese Patent Application Laid-Open No. 1-289948 discloses a film image input device using a film cartridge, but does not describe a technology relating to a film cartridge having a single spool and an interface between the film image input device. . For example, as shown in FIG. 62, one end of a photographic film 43 is fixed to a supply spool 44, the other end is fixed to a take-up spool 45, and the two spools 44, 45 are rotatably supported at fixed intervals. When using the thus configured film cartridge 46, the following problems occur.

That is, since the interval between the two spools 44 and 45 is defined in the film cartridge 46, the design of the film image input device 42 cannot be freely designed, and the film cartridge 46 has a structure that straddles the imaging optical system. Therefore, the film image input device 46 becomes large in order to guarantee the loadability, and a large space is required for storage.
In addition, since the film surface is exposed at least one frame on both the front and back sides, there is a possibility that dust may enter from that portion,
Since the screen frame 47 is provided in the film cartridge 46, various problems occur, such as a mechanism for matching the focal plane of the imaging optical system to the image plane of the film cannot be freely designed.

When the film has a magnetic recording layer, there is another problem that the arrangement of the recording / reproducing magnetic head with respect to the magnetic recording layer is restricted by the shape of the film cartridge. In addition, the film is made by coating a photosensitive emulsion on a base such as acetate or polyester. Occurs.

That is, as shown in FIG. 63, the film (particularly, the developed film) is strongly curled (FIG. 63).
(A)), if it is to be stretched, it will bend in the width direction as shown in FIG. 63 (B), and if one end of the film is automatically wound on the take-up reel, the tip of the strongly curled film Enters the opposite side of the take-up reel from the take-up side, making it impossible to take up. Furthermore, since the film has a large rigidity and the film roll has a large restoring force, there is a problem that the film is easily bent or loosened. Also, while the film is wide, the winding diameter is relatively small due to the limited number of frames. As a result, the form of the film cartridge is different from that of the tape cassette. Therefore, when a film cartridge is mounted on the cartridge mounting section, a cartridge mounting mechanism different from the tape cassette mounting mechanism is required.

Further, in order to always reproduce a film image properly by the film image input device, it is necessary to prevent the film from being damaged and to perform fading correction of the film image. In addition, there are a negative film and a positive film in the film. Is complicated. Furthermore, when the film image input device is activated, nothing may be displayed. In this case, no image is displayed because the film is not set, or no image is captured because a frame in which nothing is imaged is captured. There is a problem that cannot be distinguished.

When the film is wound up and unwound with a single reel motor, the driving force may be transmitted from the reel motor to a supply reel or a take-up reel via a swing gear mechanism. This swinging gear mechanism swings in accordance with the rotation direction of the reel motor, and transmits a driving force to the supply reel or the take-up reel only in the film winding direction. When the film is sent out from the cartridge), the supply reel cannot be driven in the film sending direction using the swinging gear mechanism.

Further, when scanning the film image in the X direction and the Y direction by relatively moving the film and the image pickup means, the scanning in the X direction may be performed by feeding the film. In this case, the speed ratio between the frame feed speed and the scan speed in the X direction needs to be about 20 times, and it is not possible to cope with the above speed ratio only by changing the rotation speed of the reel motor. There is a problem that scanning cannot be performed by one reel motor. When performing frame advance, a notch or the like indicating a frame position is provided for each frame of the film, and by detecting the notch or the like with a frame detector, the frame can be accurately advanced one frame at a time. X as above
When scanning in the direction by sending the film,
Depending on the scan position before frame advance, a notch or the like of the same frame may be detected again at the next frame advance. In this case, there is a problem that the same frame is reproduced.

Further, the film has a magnetic recording layer,
In the case where trimming information or the like is magnetically recorded / reproduced on the magnetic recording layer at the time of frame advance, the frame advance speed must be kept constant. SUMMARY OF THE INVENTION It is an object of the present invention to provide a film having a simple structure capable of obtaining the flatness of a still photographic film fed to an imaging area by a film transport means, and preventing the film from being streaked. An image input device is provided.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a film image input apparatus and a film transport apparatus according to the present invention will be described below in detail with reference to the accompanying drawings. [First Embodiment] FIG. 1 is a block diagram showing a first embodiment of a film image input apparatus according to the present invention. As shown in FIG. 1, a film 2 (see FIG. 3) used in the film image input apparatus 1 has one film corresponding to a position where an image is recorded.
It has one perforation 3 for the image.
However, at least the virtual image position 4 immediately before the image of the first frame and the virtual image position 5 immediately after the image of the last frame.
There is one perforation corresponding to.

As shown in FIGS. 3 to 5, the film cartridge 6 used in the film image input device has a single outlet opening 7 for feeding the film 2.
And a single spool 8. The spool 8 has one end in the longitudinal direction of the film 2 fixed thereto, and is supported by the main body of the film cartridge 6 so as to be rotatable in both the direction in which the film 2 is sent out and the direction in which the film 2 is wound.
Before the film 2 is loaded into the film image input device, the entire length of the film 2 is usually wound around the spool 8 and is stored in the film cartridge 6.

The spool 8 of the film cartridge 6
The film cartridge 6 is provided with means for preventing the film from being loosened in order to smoothly feed the film 2 out of the film cartridge 6 by rotating the film cartridge 6. As an embodiment of the means, as shown in FIG.
In any case, the winding diameter of the film 2 can be kept to a minimum, so that when the spool 8 receives a rotational force in the direction in which the film 2 is sent out, the rotational force is transmitted to the longitudinal direction of the film 2 without waste. Therefore, the leading end of the film 2 is smoothly fed out from the film outlet opening 7 of the film cartridge 6.

Another characteristic of the film cartridge 6 is that the film 2 stored in the film cartridge has been developed as shown in FIG. An optically detectable mark 1 which is displayed by a label 10 and which corresponds to the display.
1 is printed.

As shown in FIG. 2, the film image input device 1 of the present invention is provided with a cartridge storage opening 12 for storing the film cartridge 6, and the shape of the opening 12 is the same as that of the film cartridge 6. Since it has a shape substantially equal to the shape, there is no possibility of loading a different type of cartridge by mistake. As shown in FIG. 1, the film image input device 1 is provided with a film supply means 13 which can be driven to rotate in both directions, and the film supply means 13 is provided at a position where it is engaged with the spool 8. ing.

Further, the film image input device 1 is provided with a loading completion detecting means 14 (FIG. 2).
It is detected that the loading of is completed. The cartridge storage section 15 has an optical mark reading means 16 (FIG. 1).
After the film 2 has been developed and the type of the film 2 is confirmed, the film is locked by the locking means 17 so that the storage opening is not accidentally opened. The image signal processing circuit 19 is switched according to the type of the film, and the supply means 13 starts rotating in the direction in which the film 2 is fed.

However, if there is no label 10 on which the developed optical mark 11 is printed on the film cartridge 6 or if the content of the printed mark 11 is different, the film image input device 1 displays a warning to that effect. Wait state. As another function, the warning indication is displayed, and the closed storage opening 12 is automatically opened so that the film cartridge 6 can be taken out.

If it is confirmed that the film is a developed film as expected, the leading end of the film 2 is sent out from the film outlet opening 7 of the cartridge body by the rotation of the supply means 13. Also, the cartridge storage unit 1
5, an optical sensor 20 for detecting the presence or absence of the film 2 is provided at a position where the perforation 3 of the film 2 is located. This optical sensor 20 confirms that the film 2 has been sent out. The end of the developed negative film in the width direction (FIG. 3) is usually slightly colored so that it can be detected optically. In the case of a reversal film, if the end reaches an unexposed area, it is substantially opaque, and can be detected shortly after the leading end of the film has passed.

The film take-up means 21 rotates at a somewhat higher speed in the longitudinal direction of the film 2 than the film supply means 13 almost simultaneously with the start of the rotation of the film supply means 13. The film image input device 1 is provided with a pair of opening frames 22 as means for temporarily stopping the film 2 at a predetermined position and forming a screen frame in order to capture a film image. The opening frame 22 opens and closes in synchronization with the movement of the film supply means 13 and the film winding means 21. That is, the opening frame 22 is closed only when the driving of both the means 13 and 21 is stopped, and in other cases, the opening frame 22 is in an open state at an interval that does not prevent the film 2 from passing. Accordingly, the leading end of the film 2 easily passes through the opening frame 22 and reaches the winding spool 23. The take-up spool 23 is formed so that the leading end of the film 2 can be easily wound around, so that the film 2 starts to be wound around it.

After confirming that the film 2 has been sent out, the film supply means 13 stops after a certain period of time, and applies tension to the film 2 in the direction opposite to the traveling direction. The tension is for preventing the film 2 from sagging, and is not so strong as to damage the film 2. The film presence / absence detecting means 20 is also capable of detecting the perforations 3 (FIG. 3), and has an arrangement relationship in which any perforations can be detected when the first frame of the film image reaches the position of the opening frame 22. The counter 24 connected to the film presence / absence detecting means 20 counts the number of times the perforations 3 have been detected, so that when the image of the first frame reaches the position of the opening frame 22, the film winding means 2
1 is stopped and the opening frame 22 is closed.

At this time, the film image is projected on the image sensor 26 through the imaging optical system 25 and reproduced as a video on the video monitor 18 through the image signal processing circuit 19. After a predetermined time or when the frame feed button 27 is pressed, the opening frame 22 is opened, and the film winding means 21 subsequently resumes rotation. At this time, the image of the first frame is continuously displayed on the video monitor 18 by the image signal storage circuit 28 provided in the image signal processing circuit 19.

The subsequent progress of the film 2 and detection of perforation, and the sequence of stopping the film 2 and reproducing the video are almost the same as the sequence of the first frame. The film image input device 1 is a film if the number of photographed images displayed on the film cartridge 6 by the optically detectable mark 11 (FIG. 4) matches the number of frames reproduced by the film image input device 1 (FIG. 1). At the same time as the winding means 21 ends, the reproduction of the image is ended, and the film supply means 13 is driven to rotate in the direction opposite to the feeding direction, and the film 2 is rewound into the film cartridge 6.
At this time, the opening frame 22 is kept open and the film winding means 21 applies tension in the direction opposite to the traveling direction of the film 2. The film presence / absence detecting means 20 detects the passing perforations 3 and subtracts the value of the counter 24.

When the value of the counter 24 becomes (-1), it corresponds to the time when the entire film has passed the film presence detecting means 20. Then, after a certain period of time, it is displayed that the film cartridge 6 can be discharged, and the lock 17 of the cartridge storage opening (FIG. 2) is displayed.
Cancel. Or the cartridge storage opening 1 automatically
2 is opened so that the film cartridge 6 can be taken out.

However, a slight problem in the first embodiment is that immediately after the film cartridge 6 is loaded into the camera, the entire length of the film is once sent out from the cartridge, and the film is taken back while the film is being rewound in order from the frame at the rear end of the film. In the case of using a film taken by a camera of the following format, the reproduction method described in the first embodiment reverses the order of photography and the order of reproduction, so that the viewer of the reproduced image feels somewhat abnormal. Maybe. If there is a frame that has not been photographed between frames that have already been photographed, this is meaninglessly reproduced.

As one means for solving the above-mentioned problem, information of a photographing start frame number, a photographing end frame number, and a non-photographing frame number is optically detected by a viewer in a developing laboratory or by the viewer of the reproduced image on the film cartridge 6. There is a way to add it as a mark, but it is not very efficient. [Second Embodiment] The second embodiment of the present invention described below can solve these problems.

That is, as shown in FIG. 7, a film on which a magnetic recording layer is applied to the film 2 is used. The recording start frame number and the photographing end frame number are recorded at the recording position 30, and whether or not the photographing has been completed at the corresponding position 31 of each frame is recorded. As shown in FIG. 6, the film image input device is provided with a magnetic head 32 which is in contact with the magnetic recording layer of the film, adjacent to the film outlet opening 7 of the film cartridge 6.

When the film cartridge 6 (FIG. 7) containing the magnetically recorded film is loaded in the film image input device 29, various operations until the film is sent out are as described above. Thereafter, the magnetic recording information is read via the magnetic head 32 and the magnetic reading circuit 34 in synchronization with the detection of the presence or absence of the film 20 by the film presence detecting means 20 corresponding to the position of the 0th frame on the virtual image plane. By decoding the information, the microcomputer 35 stores the photographing start frame number and the photographing end frame number. If the shooting start frame number is larger than the shooting end frame number, the microcomputer 35 fast-forwards and stops the film to the shooting start frame position while counting the number of perforations by the film presence / absence detecting means 20 and the counter 24. .

At this time, the magnetic recording information corresponding to each frame is read by the magnetic head 32, and if there is an unphotographed frame, its number is stored. Other operations are the same as those described above. After the film is stopped at the position of the shooting start frame, the image reproduction of each frame from the shooting start frame to the shooting end frame is performed in order while rewinding the film into the film cartridge 6. At this time, if there is an unphotographed frame stored at the time of fast forward, the reproduction of that frame is omitted and the process proceeds to the next frame. The stored end photographing frame number is compared with the counter value of the perforation number to determine the photographing end frame. When the reproduction of the shooting end frame is completed, the film is loaded into the film cartridge 6 in the same manner as in the first embodiment.
Rewind inside.

Conversely to the above example, when the photographing start frame number is smaller than the photographing end frame number, the image of each frame can be reproduced while transporting the film in the direction of being sent out from the film cartridge 6. Still another embodiment is also effective. That is, instead of using an optical mark for indicating the type of film and the presence or absence of development on the film cartridge 6 in the first embodiment, the film image input device in the second embodiment is recorded by a film maker and a developing laboratory. Magnetic recording information can be used. Third Embodiment FIG. 8 is a perspective view showing the appearance of a third embodiment of the film image input device according to the present invention. As shown in FIG. 1, the film image input apparatus 100 illuminates a developed still photographic film 124 by an illumination unit 112 and illuminates the photographic film 124 with a photographing lens (zoom lens) 114 and a solid-state image sensor 116 such as a CCD. And outputs an image signal to the video monitor 119 (FIG. 9) to reproduce the film image on the video monitor 119.

The film 124 is a negative film or a positive film which has been developed and is stored in a film cartridge 127 having two spools (two axes).
Set to 5. The illumination unit 112 also serves as a lid for the cartridge mounting portion 115, and rotates in the direction of arrow AB to open and close the cartridge mounting portion 115. The illumination unit 112 has a light source 118, a reflector 120, and a diffuser 122, as shown in FIG. The light is then diffused into the film illumination light. The illumination light irradiates the image of the film 124 and the photographing lens 1
It is led to 14.

The photographing lens 114 is a zoom lens including a variable power lens 126, and is driven by a zoom driving unit 128 that inputs a zoom signal from a control unit 132.
Are moved in the left-right direction in FIG. 9 to perform a zoom operation, thereby zooming in and out on the image of the film 124. Also, the zoom position detecting unit 130 is a variable power lens 1
The movement position (zoom position) of 26 is detected, and the zoom information is added to the control unit 132.

The film drive unit 134 receives various film feed signals from the control unit 132, and the film cartridge 127 according to the input signal.
Is moved in the X direction (the direction perpendicular to the plane of FIG. 9). Note that the film drive unit 134 moves the film 124 at high speed during fast-forward, rewind, or frame feed, and moves the film 124 at low speed during scan feed.

On the other hand, the lens driving section 138
Shooting lens 114 according to the scan signal added from
Then, the CCD 116 is moved in the Y direction (the vertical direction in FIG. 9). That is, the film 1 by the film driving unit 134
By the scan feed of 24 and the movement of the photographing lens 114 and the CCD 116 by the lens driving unit 138, the image of the film 124 can be scanned in the vertical and horizontal directions.

The film image photographed by the photographing lens 114 forms an image on the light receiving surface of the CCD 16 and is converted by each sensor of the CCD 16 into a signal charge of an amount corresponding to the light intensity. The signal charges are sequentially read out and output to the image signal processing circuit 117. The image signal processing circuit 117 includes a sample hold circuit, a white balance circuit, a gamma correction circuit, a matrix circuit, an encoder circuit, and the like. After performing predetermined signal processing by these circuits, an image signal indicating a film image is displayed on a video monitor. 119 is output. As a result, an image of the film 124 is displayed on the video monitor 119. When the film 124 is a negative film, the image signal processing circuit 117 also performs signal processing for performing negative / positive inversion.

The CCD rotator 140 rotates the CCD 116 by 90 ° in the clockwise direction (CW direction) when viewed from the photographing lens side, according to a rotation command signal applied from the controller 132.
After rotating by 80 ° and 270 °, the rotation position detecting unit 142
The rotational position of the CD 116 is detected, and the position information is output to the control unit 132. When the image reproduced on the video monitor 119 is rotated 90 ° in the counterclockwise direction (CCW direction), the monitor image can be erected by rotating the CCD 116 90 ° in the CW direction. Similarly, the image reproduced on the video monitor 119 is CW
If the CCD 116 is rotated 90 ° in the
When the image reproduced on the video monitor 119 is turned upside down by rotating 270 ° in the W direction (90 ° in the CCW direction), the monitor image is erected by rotating the CCD 116 by 180 ° in the CW direction. Can be.

The control unit 132 includes a zoom position detection unit 130,
Rotational position detector 142, film information recording / reproducing unit 144
And a signal from the operation unit 146, based on the zoom drive unit 128, the film drive unit 134, the lens drive unit 138,
It outputs various control signals to the CCD rotating section 140 and, if necessary, transmits film information to the film information recording / reproducing section 14.
4 and the film information is recorded on the film 124.

The film information recording / reproducing unit 144 records film information (for example, zoom information, scan position information, CCD rotation information, etc.) on a magnetic recording surface or the like of each frame of the film 124 by a signal from the control unit 132. The control unit 13 reads the film information from the film 124 and
Output to 2. The frame detection of the film 124 can be performed by reading the frame information recorded for each frame of the film 124 by the film information recording / reproducing unit 144 or by referring to FIG.
This is performed by frame detection means for optically or mechanically detecting a notch 124A indicating a frame position provided in advance on the film 124 as shown by 0, and the frame detection means outputs frame information to the control unit 132. . When the frame position is detected optically or mechanically, a hole may be provided for each frame of the film instead of the notch 124A.

Further, as shown in FIG.
Long notches 124B and 124
C are formed, and these notches 124B and
By detecting 4C, the beginning and end of the film 124 can be detected. FIG. 11 shows an example of the frame detection means. The frame detecting means includes a photo interrupter 147,
Is a hole 124E indicating a frame position provided for each frame.
Is optically detected, and a frame detection signal is output to a frame number calculation unit (counter) 148. The frame number calculation unit 148 calculates the frame number of the currently reproduced film image based on the frame detection signal supplied from the photo interrupter 147. That is, when the beginning of the film 124 is detected, the frame number calculating section 148 resets its count value to 0,
Thereafter, when the frame detection signal is input while the film 124 is being fed in the forward direction (+ X direction), the count value is counted up. When the frame detection signal is input while the film 124 is being fed in the reverse direction (−X direction). , Count down the count value.

The image signal processing circuit 117 includes a CCD 116
The information indicating the frame number is added from the frame number calculation section 148 in addition to the image signal from the image signal processing circuit 1.
Reference numeral 17 reads a character signal indicating the frame number from a character generator (not shown) based on the frame number information, inserts the character signal into an image signal from the CCD 116, and outputs it to the video monitor 119. As a result, the frame number is superimposed on the image on the video monitor 119. As a method of displaying the frame number, a method of always displaying the frame number in the reproduced image, a method of displaying the frame number for a fixed time after the frame number is changed, and the like can be considered. In the case of the last frame, the last frame can be notified by blinking the frame number, for example.

As shown in FIG. 12A, a contact type electric contact 149 may be used as the frame detecting means. The electric contact 149 is turned on at the position of the hole 124E as shown in FIG. 12 (B), and is cut off at other positions, so that the top position can be detected. Further, the frame number is detected, for example, by using the film 12
If there is a magnetic recording section, that is, a magne layer, the frame number information is recorded on the magne layer, and the frame number information is detected by reproducing the frame number information by the information recording / reproducing section 144 at the time of frame advance. Is also good.

When audio information is recorded on the magne layer of the film 124, the audio information is detected by the magnetic head 150 as shown in FIG. The audio circuit 151 has a storage unit for temporarily storing audio information. When audio information is input from the magnetic head 150, the audio circuit 151 stores the audio information in the storage unit and sends a signal indicating the presence or absence of the audio information to the control circuit 152.
Output to Frame number information is added to the other input of the control circuit 152 from the frame number calculation section 148, and the control circuit 152 outputs a signal indicating the presence or absence of audio information to the image signal processing circuit 117 together with the frame number information.

The image signal processing circuit 117 displays frame numbers in which audio information is recorded and frame numbers in which audio information is not recorded in a distinguished manner. For example, the display color of the frame number is changed or the frame number blinks depending on the presence or absence of the audio information. Then, when an operation of outputting a sound is performed while observing a change in the display of the frame number, the sound information temporarily stored in the sound circuit 151 can be output to a speaker (not shown) to reproduce the sound.

FIG. 14 is a main block diagram showing a modified example of the film image input device shown in FIG. The difference from FIG. 9 is mainly that a frame memory 153 is provided, and this frame memory 153 records an image signal for one frame. The frame detector 154 detects the frame position of the film 124 and outputs a frame detection signal to the control unit 132.
When the frame detection signal is input from the frame detector 154 at the time of frame feeding, the film driving unit stops film feeding by the film driving unit. As a result, the frame 124 is advanced.

The control section 132 controls the image signal processing circuit 117 so as to enable or disable the operation, and also controls the writing of the image signal to the frame memory 153. That is,
After the frame advance is completed, the control unit 132 controls the image signal processing circuit 1
17 to enable the image signal of the frame currently being photographed to be sequentially output to the frame memory 153 and to enable the writing of the image signal to the frame memory 153.
The image signals sequentially read from the frame memory 153 are output to the video monitor 119 and reproduced.

On the other hand, various signals are applied to the control unit 132 from the operation unit 146. When the fast-forward signal or the frame-forward signal is applied, the control unit 132 controls the film drive unit 134 to control the film 124. Fast forward or frame forward. At the same time, the operation of the image signal processing circuit 117 is disabled, the output of the image signal is stopped, and the update of the storage content of the frame memory 153 is prohibited. As a result, at the time of film feed such as fast forward or frame feed, the film image taken immediately before the film feed is reproduced on the video monitor 119 as a still image.

FIG. 15 is a main block diagram showing another modified example of the film image input device shown in FIG.
4 differs mainly in the connection method of the frame memory.
That is, in FIG. 14, the frame memory 153 is connected in series to the output of the image signal processing circuit 117, but in FIG. 15, the frame memory 155 is connected in parallel. With this connection, an image signal other than when the film is fed can be directly applied from the image signal processing circuit 117 to the video monitor 119 without passing through the frame memory 155, so that the image quality is improved. When the film is fed, the image signal is read from the frame memory 155 as in FIG.
The film image photographed immediately before the film feeding is reproduced on the video monitor 119 as a still image. Note that, by compressing and storing image signals of a plurality of frames in the frame memory 155, a multi-image (for example, an index image or a composite image) can be reproduced.

FIG. 16 shows the magne layer 125 of the film 124.
FIG. 17 is a block diagram showing a reproducing system for reproducing various information recorded on the magne layer 125 of the film 124. As shown in FIG. As shown in FIG. 16, first, at the time of shooting, zoom information from the zoom position detection unit 130, F number information calculated based on an AE sensor (not shown), shutter speed information from the shutter speed setting dial 133A, UP / DO of pop-up type flash 133B
Information indicating WN (presence or absence of strobe light), exposure correction information from exposure correction dial 133C, and timer 133D
The shooting date and time information from the camera is stored in the IC memory 135 of the camera body.
The information is input to the magnetic head 1 via the interface 157 and the head amplifier 158 at the time of frame advance.
At step 59, the subject 160 is recorded on the magne layer 125 at the upper end of the frame where the image was taken.

On the other hand, as shown in FIG. 17, when the film cartridge 127 on which the developed film 124 is wound during reproduction is set in the film image input device 100 and the film 124 is fed by frame, the film 124 is transferred. (For example, photographing information input from the camera at the time of photographing as described above) is read via the magnetic head 162, and this information is read via the head amplifier 163 and the IC via the interface 164. It is stored in the memory 165.

When the image signal photoelectrically converted by the CCD 116 is applied to the image signal processing circuit 117, the photographing information stored in the IC memory 165
The image signal is supplied to the image signal processing circuit 117 via the CPU 6 and is converted into a character signal indicating shooting information. Then, the character signal is mixed with the image signal and output to the video monitor 119, whereby the shooting information is superimposed on the image on the video monitor 119. If pseudo-zoom information (information for enlarging a specific range during printing without zooming the photographing lens) is recorded in the photographing information, the pseudo-zoom information recorded on the film 124 is included in the pseudo-zoom information. By automatically zooming the photographing lens 114 of the film image input device based on this, a film image in a pseudo zoom state at the time of photographing can be reproduced on the video monitor 119.

FIG. 18 shows details of the film information recording / reproducing section 144 shown in FIG. The film cartridge 127 shown in the figure includes a film supply chamber 127A,
A film take-up chamber 127B is formed, and the film 124 is fed from the film supply chamber 127A to the film take-up chamber 127B in the direction indicated by the arrow. At the upper or lower end of the film of the film 124, a magnetic layer is formed in a belt shape to form a recording track.
Necessary information such as post-recording information and trimming information is recorded and reproduced in 4B.

In the film image input apparatus, a magnetic head 162A for reproduction is provided on the film supply side (upstream side in the film feeding direction) of the film cartridge 127, and the film winding side (downstream side in the film feeding direction). Is provided with a recording magnetic head 162B. still,
The magnetic heads 162A and 162B are separated by one frame. The magnetic heads 162A and 162B are connected to a control circuit 165A via a head amplifier 163.

The control circuit 165A compresses audio information input from the microphone 165C via the A / D converter 165B during audio recording and stores the compressed audio information in the memory 165F.
At the time of frame advance, the audio information stored in the memory 165F is read and output to the recording magnetic head 162B via the amplifier 163. Thereby, the magnetic recording track 1
Voice information is digitally recorded in 24B.

The control circuit 165A inputs audio information from the magnetic recording track 124B via the magnetic head 162A for reproduction and the amplifier 163 at the time of frame advance during audio reproduction, and stores the audio information in the memory 165F. The audio information is read out from the 165F, and after expanding the audio information, it is output to the speaker 165F via the D / A converter 165D. Thus, the audio information recorded on the recording track 124B is reproduced as audio.

The operation of the information recording / reproducing apparatus for a film for a film image input apparatus according to the present invention, constructed as described above, will be described. First, recording will be described.
The film 124 is sent in the direction of the arrow in FIG. 18 (the forward direction of the earlier shooting), and the image of the frame 124A is currently located in the shooting frame. In this state, audio information is input from the microphone 165C. The input audio information is stored in the memory 1 via the A / D converter 165B and the control circuit 165A.
65F.

Then, in order to display the next new frame,
When frame advance of the film 124 is started, at the same time, the control circuit 165A reads the input audio information from the memory 165F, and transmits this audio information via the amplifier 163 and the magnetic head 162B for recording to the magnetic recording track of the frame 124A. Record at 124B. Next, the reproduction time will be described. At the time of reproduction, the film 124 is advanced by the frame in the direction of the arrow (forward direction), and in a state where the frame 124A shown in FIG. 18 is displayed, the magnetic head 162A for reproduction uses the magnetic recording in which audio information for the frame 124A is recorded. The tracing of the track 124B has been completed, and this audio information is input to the control circuit 165A via the amplifier 163, and is recorded in the memory 165F. Then, when there is an instruction such as an audio output button, the control circuit 165A reads the audio information from the memory 165F, expands the audio information, and
The signal is output to the speaker 165E via the / A converter 165D. This allows the user to listen to the voice commenting on the image while viewing the image.

In the above-described embodiment, the read-only magnetic head 162A is provided on the upstream side in the film feed direction, and the write-only magnetic head 162B is provided on the downstream side.
A magnetic head for recording / reproduction may be provided on each of the downstream side and the upstream side. That is, when the film feeding direction is reversed, the upstream side and the downstream side are reversed, but the recording / reproducing magnetic head is switched and used so that the downstream side is always the recording head and the upstream side is the reproducing head. Thereby, the present invention can be applied even when the film feeding direction is reverse.

When the film feeding direction at the time of recording and the film feeding direction at the time of reproduction are different, it is necessary to reversely reproduce the audio information stored in the memory so as to obtain normal audio.
The recording of the information input by the camera is not limited to the magne layer of the film, but may be optically recorded on the photosensitive layer or recorded on the IC memory mounted on the film cartridge. The information to be recorded on the film from the camera includes prewind information indicating that photographing has been started after winding the film in advance, and the film on which the prewind information is recorded is stored on a video monitor via a film image input device. In the case of reproducing, the film in the film cartridge may be automatically pre-wound, and then sequentially advanced.

FIG. 19 is a main block diagram of a film image input apparatus provided with an exposure adjusting circuit 167 and a color adjusting circuit 168. In the figure, a brightness level is set in advance in the exposure adjustment circuit 167 so that the monitor image has a preferable brightness, and the exposure adjustment circuit 167 determines the brightness level of the brightness signal Y input from the image signal processing circuit 117 in advance. Compared with the set luminance level, the aperture of the iris 169 is controlled to be larger when the luminance of the film image is dark, and to be smaller when the luminance of the image is bright.

On the other hand, in the color adjustment circuit 168, a chroma level is set in advance so that the monitor image has a preferable color, and the color adjustment circuit 168 determines the chroma level of the chroma signal C input from the image signal processing circuit 117 in advance. Compared with the set chroma level, the chroma signal is adjusted so that the film image has an optimal color.

FIG. 20 is a plan view showing an example of the operation unit 146 of the film image input device 100. This operation unit 14
Reference numeral 6 denotes, for example, an infrared remote control transmitter, which transmits an infrared remote control signal to a receiver (not shown) on the film image input device in response to operation of various switches. The operation unit 146 includes zoom switches 146A and 146B for zooming in and out of the image, a scan lever 146C for scanning the film image, and switches 146D and 146D for rotating the CCD 116 to erect the monitor image.

6T and the like are provided. In FIG. 20, 146W is an INV switch that is pressed before inputting new information.

Next, the operation of the thus configured film image input apparatus according to the present invention will be described. First,
The film cartridge 127 having the developed film 124 is set in the film image input device 100.
Thus, the control unit 132 controls the first one of the films 124.
The film driving unit 134 is controlled so that the frame is located between the illumination unit 112 and the photographing lens 114. The image of this frame is illuminated by the illumination unit 112, and the photographing lens 114, the CCD 116, the image signal processing circuit 11
The image is output to the video monitor 119 via the.

To zoom or scan the image displayed in this state, use the zoom switch 1 of the operation unit 146.
By operating 46A, 146B or the scan lever 146C, a zoom signal or a scan signal is applied to the control unit 132. The control unit 132 controls the zoom driving unit 128 and the lens driving unit 13 according to these signals input from the operation unit 146.

Zooming and scanning of film images. As a result, the film image of the entire frame is appropriately trimmed and reproduced on the video monitor 119 as a trimmed image. The zoom information, scan position, C
The reproduction information of the film image such as the CD rotation information is sent from the control unit 132 to the information recording / reproducing unit
4 can be recorded on the magne layer of the frame.

Next, when the image of the next frame is reproduced by feeding the film 124 frame by frame, a mode selected by a mode selection switch (not shown) for selecting a manual mode, an auto mode, or a standard auto mode is selected. The reproduction of the film image is performed. That is, the manual mode is a mode in which an image of a new frame is reproduced in the same state as the zoom and scan state of the previous frame, and the auto mode is a mode in which the image is automatically reproduced based on the reproduction information recorded on the film 124. The standard auto mode is a mode in which an image of a new frame is reproduced in a standard state regardless of the zoom and scan states of the previous frame. The standard condition is
This refers to a state in which an image of an entire frame is filled on the entire screen of the video monitor 119, and there are two standard states, that is, a case where a subject is horizontally projected on the film 124 and a case where the subject is vertically projected. Also, of these two standard states,
Which of the standard states is reproduced is determined by the rotation position detector 14.
2 automatically selected according to the CCD rotation information.

Next, a method for inputting reproduction information (zoom information, scan position, etc.) of a display image of each frame using the operation unit 146 and an automatic reproduction method using the reproduction information will be described with reference to a flowchart of FIG. explain. In this case, the recording means of the reproduction information may be a magnetic layer of a film, an IC memory mounted on a cartridge, an IC memory in a film image input device, or the like.

First, the frame 124 is advanced by pressing the frame advance switch 146H for performing frame advance in the forward direction, and the image of the frame is displayed on the video monitor 119 (step 170). Next, the user operates the zoom switches 46A and 46B, the scan lever 46C, and the like while viewing the displayed image to set a desired reproduced image (step 172).
Here, if necessary, the standard display time (for example, 5
Seconds), the time setting switch 146P,
Press 146R to correct (step 174). Thereafter, the input switch 146M is pressed to input reproduction information (step 176). The above procedure is repeatedly executed until the input of the reproduction information of all the frames is completed (step 178).

After the input of the reproduction information, when the mode selection switch is set to the auto mode and the start switch 146S is depressed, the reproduction information is read out, and the reproduction information is read out based on the reproduction information.
The frames are automatically reproduced one by one (step 180). On the other hand, when it is desired to stop the reproduced image for a set time or more during the automatic reproduction, the stop switch 146T is pressed to stop the image (steps 182 and 184). Thereafter, when the image is reproduced again, the start switch 146S is pressed (steps 186, 80). Also, when the reproduction is performed sequentially and the reproduction of the image of the last frame is completed, the automatic reproduction is completed (steps 188 and 189).

When the input is wrong or when the user wants to change the input, the user presses the INV switch 146W when the corresponding frame is displayed on the video monitor 119, and then presses the erase switch 146N. 1
The automatic reproduction information for the image displayed at 19 can be deleted. To erase the automatic reproduction information of all the films in the film cartridge, press the erase switch 146N together with the INV switch 146W.

Next, a method of inputting reprint information for an appropriate frame using the operation unit 146 will be described with reference to the flowchart of FIG. Here, step 190
And 192 correspond to steps 170 and 17 described above, respectively.
2 and the description is omitted. However, the zoom of the reproduced image is based on the video monitor 1
Since it is higher than the screen of 19, it can be up to, for example, about 10 times. However, when inputting the reprint information, the standard magnification (for example, the magnification at which the image of one entire frame fills the screen) does not exceed 3 times. Restrict to This is because the image quality of the print image is not reduced. Note that 3 times is the maximum magnification that can maintain image quality as a normal photographic print.

At step 192, the reproduced image (trimming)
Is set, the number-of-prints setting switch 146L is pressed to set the number of prints (step 194). Here, to reduce the number of prints, after pressing the INV switch 146W, the number setting switch 146L is pressed. When pressed once with these switches 146W and 146L, the number of prints increases or decreases one by one. After setting the number of prints, the input switch 146M is pressed to input the trimming information and the number of prints. The above procedure is repeatedly executed until the input of the print information of all the frames is completed (step 198). The erroneous input can be erased in the same manner as the procedure described in the above-mentioned automatic reproduction method.

Similarly, the arm plate 233B of the lower swing gear mechanism 229 moves to the gear 2 when a rotational driving force is applied to the gear 231B via the gear 231A.
Since a rotational load is applied to the swing gear 235B that meshes with the gear 31B, the swing gear 235B rotates in the same direction as the rotation direction of the gear 231A (gear 231B).

The swinging restriction means for controlling the swinging range (rotation range) of the swinging gear mechanisms 228, 229 includes cam plates 238, 239, a pressing member 240, a stopper 241,
242A, 242B and the like. Cam plate 23
8, a long hole 238A is formed.
A is engaged with a pin 243 implanted on the base plate 208. Thus, the cam plate 238 is movably disposed on the base plate 208. A pin 238B is implanted in the cam plate 238, and the pin 238B is engaged with a groove cam 283 (FIG. 38) described later. Therefore,
The cam plate 238 moves according to the turning position of the groove cam 283.

The cam plate 238 has a cam groove 238C and steps 238D and 238E.
8 is provided with a cam plate 239 having a cam groove 239A.
44 (see FIG. 29). On the other hand, a pin 245A engaging with the cam groove 239A of the cam plate 239 is implanted in the arm plate 233A, and a pin 245B engaging with the cam groove 239C of the cam plate 238 is implanted in the arm plate 233B.
(See FIG. 28).

The holding member 24 is provided on the base plate 208.
0 is rotatably disposed by a pin 240A,
The pressing member 240 is provided with a stepped portion 238D of the cam plate 238,
It is appropriately rotated by 38E. That is, as shown in FIG. 30, the upper end of the pressing member 240 is formed in a substantially C shape, and has stopper surfaces 240B and 240C. A substantially fan-shaped convex portion 240D is formed at the lower end of the holding member 240. Thereby, the step portion 23 of the cam plate 238 is
When 8D comes into contact with the convex portion 240D, the pressing member 240 rotates in the CW direction in FIG. 27, and when the cam plate 238 moves upward and the step portion 238E comes into contact with the convex portion 240D, the pressing member 240 It rotates in the CCW direction.

Next, the regulation of the rotation range of the lower swing gear mechanism 229 in the above configuration will be described. When the cam plate 238 is at the position shown in FIG.
The pin 245B on 33B enters the narrow groove of the cam groove 238C, thereby fixing the arm plate 233B to the neutral position (the position where the swing gear 235B does not mesh with any of the gears 246B and 247B). Therefore, the rotational driving force from the reel motor 227 is transmitted to the swing gear 235B.
235B, the swing gear 235B idles at the neutral position without swinging.

On the other hand, when the cam plate 238 moves upward by a predetermined amount in FIG. 27 and the pin 245B on the arm plate 233B comes into the wide groove of the cam groove 238C (see FIG. 29), the arm plate 233B can rotate. Becomes And the reel motor 2
When the gear 231B is rotated in the CCW direction by the arm 27, the arm plate 233B also rotates in the CCW direction to abut against the stopper 242A, and the swing gear 235B is connected to the gear 2
46B is engaged. Thereafter, when the gear 231B is rotated in the CCW direction, the rotational driving force is transmitted to the gear 246B via the swing gear 235B, and further transmitted to the gear 209A of the supply reel 209 via the gear 246A coaxial with the gear 246B. Is transmitted. Thus, the supply reel 209 is rotated in the CW direction. Similarly,
When the gear 231B is rotated in the CW direction by the reel motor 227, the arm plate 233B also rotates in the CW direction to abut the stopper 242B, and the swing gear 235
B comes to mesh with the gear 247B. Thereafter, when the gear 231B is rotated in the CW direction, the rotational driving force is transmitted to the gear 247B via the swinging gear 235B, and further transmitted to the gear 204C of the take-up reel 204 via the gear 247A coaxial with the gear 247B. Is transmitted to Thereby, the take-up reel 204 is rotated in the CCW direction.

Next, the regulation of the rotation range of the upper swing gear mechanism 228 will be described. When the cam plate 238 is at the position shown in FIG.
45A enters the narrow groove of the cam groove 239A, whereby the arm plate 233A moves the oscillating gear 235A to the gear 2
It is forcibly rotated to a position where it meshes with 46A. At this time, the pressing member 240 is connected to the step portion 23 of the cam plate 238.
8D, the stopper surface 24 is rotated in the CW direction.
0B (FIG. 30) abuts against the tip of the arm plate 233A to prevent the arm plate 233A from rotating in the CW direction.

Here, when the gear 231A is rotated in the CW direction by the reel motor 227, the arm plate 23
3A is rotated in the CW direction.
33A is pressed by the stopper surface 240B of the pressing member 240 and does not rotate because the pin 245A enters the narrow groove portion of the cam groove 239A, so that the swing gear 235 does not rotate.
A rotates in the CCW direction while meshing with the gear 246A. As a result, the gear 246A rotates in the CW direction,
The supply reel 209 rotates in the CCW direction.

When the cam plate 238 moves a predetermined amount from the position shown in FIG. 27 and the pin 245A on the arm plate 233A reaches the approximate center of the cam groove 239A, the arm plate 233A is rotated by the approximate center of the cam groove 239A. The movement range is regulated (see FIG. 29). In the rotation range of the arm plate 233A, the swing gear 235A cannot engage with any of the gears 246A and 247A.
At this time, the holding member 240 is rotatable,
The pressing member 240 does not restrict the rotation of the arm plate 233A. In addition, the lower swing gear mechanism 229
The pin 245B on the arm plate 233B is a cam groove 238C.
(See FIG. 29), and the supply reel 209 is moved to C by the swing gear 235B as described above.
It can be rotated in the W direction, or the take-up reel 204 can be rotated in the CCW direction.

Next, when the cam plate 238 moves from the position shown in FIG. 27 to the position shown by the dashed line and the pin 245A on the arm plate 233A reaches the wide portion of the cam groove 239A,
The rotation range of the arm plate 233A is no longer restricted by the cam groove 239A (see FIG. 29). At this time, the pressing member 240 is rotated in the CCW direction by the step 238E of the cam plate 238.

Here, when the gear 231A is rotated in the CCW direction by the reel motor 227, the arm plate 2
33A also rotates in the CCW direction to abut against the stopper surface 240C (FIG. 30) of the pressing member 240, and the swing gear 23
5A comes to mesh with the gear 246A. Thereafter, when the gear 231A is rotated in the CCW direction, the rotational driving force is transmitted to the gear 209A of the supply reel 209 via the swinging gear 235A and the gear 246A. Thus, the supply reel 209 is rotated in the CW direction.
Similarly, the gear 231A is shifted to C by the reel motor 227.
When the arm plate 233A is rotated in the W direction, the arm plate 233A also rotates in the CW direction and abuts on the stopper 241, and the swing gear 235A meshes with the gear 247A. Thereafter, when the gear 231A is rotated in the CW direction, the rotational driving force is transmitted to the gear 204C of the take-up reel 204 via the swinging gear 235A and the gear 247A.
Thereby, the take-up reel 204 is rotated in the CCW direction.

As described above, by moving the cam plate 238 forward and backward, one of the upper swing gear mechanism 228 and the lower swing gear mechanism 229 is made operable, and the reel motor 227 moves to the supply reel 209 from the reel motor 227. The rotation driving force in the CW direction can be transmitted, and the rotation driving force in the CCW direction can be transmitted to the take-up reel 204.

The lower swing gear mechanism 229 can reduce the rotation speed to 1/4 of that of the upper swing gear mechanism 228. Then, at the time of scanning the film, the supply reel 209 or the take-up reel 204 is driven via the lower swing gear mechanism 229 to feed the film at a low speed.
At the time of rewinding and frame advance, the upper swing gear mechanism 22
8, the supply reel 209 or the take-up reel 204 is driven to feed the film at a high speed. That is,
As described above, the rotation speed of the reel motor 227 can be changed about 6 times, and the gear ratio (1: 4) can be switched by the upper swing gear mechanism 228 and the lower swing gear mechanism 229. Can be changed up to about 22 to 23 times.

Further, by moving the cam plate 238 forward and backward, the swinging gear mechanism 228 is fixed so as not to swing as shown in FIG. , A rotational driving force in the CCW direction can be transmitted. That is, by rotating the supply reel 209 in the CCW direction,
The film 201 can be sent out from the film cartridge 202.

The solenoid 250 is driven when the film is delivered, and rotates the lever 249 in the CW direction to the position shown by the solid line against the urging force of the spring 249B. Thereby, the arm plate 233A is connected to the lever 2
49 for fixing at the position shown in FIG. Incidentally, 25
1 is a stopper.

According to the holding mechanism 248 having the above structure, the swinging gear 235A can be fixed so as not to swing as required, and the supply reel 209 is moved in the CCW direction, that is, in the direction in which the film can be sent out. Can be rotated. [Cartridge mounting mechanism] Figs. 32 and 33 are a front view and a plan view of a main portion mainly showing the cartridge mounting mechanism.

The pin 238B of the cam plate 238 is located at the position P1 of the cam groove 284.
, Sequentially move to positions P2, P3, P4, P5, P6, P7, and P8. P2 indicates a standby position, P3 indicates a film sending mode position, P4 indicates a film fast-forward mode position (+ frame feed mode position), P5 indicates a scan feed mode (+ X scan) position, and P6.
Indicates a stop position, P7 indicates a scan feed mode (-X scan) position, and P8 indicates a film rewind mode position (-frame feed mode position).

That is, in the ejection mode (P1), as described with reference to FIG.
8 is located at the end surface height H3, and the hold arm 257 is
It is pushed up to the rotation end in the CW direction. Thus, the lock of the cartridge holder 203 is released by the lock release member 264 integrated with the hold arm 257 (see FIG. 36).

At the standby position (P2), the end face cam 258 is rotated so that the lower end of the pin 260 comes from the end face height H3 to H2 (FIG. 32). Accordingly, as described above, the cartridge holder 203 opened at the time of ejection is
Can be locked. Film sending mode (P3)
In the end face cam 258, the lower end of the pin 260 has an end face height H.
It is rotated to a position from 2 to H1. This allows
The hold arm 257 pushes down the film cartridge 202 via the spool holding member 259, and the spool 2
The lower end of 02A is the head 209B of the supply reel 209.
(See FIG. 32).

On the other hand, in the film delivery mode (P3), the cam plate 238 is moved to the position shown in FIG. As a result, as described above, the swing gear mechanism 228 is moved to the position shown in FIG. 27, and is fixed by the pressing member 240 so as not to swing. That is, the supply reel 209 can be rotated in the CCW direction (the film sending direction) from the reel motor 227 via the swinging gear mechanism 228.
The film is sent out by the film cartridge 202.
Is inserted into the cartridge holder 203 and the cartridge holder 203 is locked. Also, when the film tip detector is turned from OFF to ON while the film is being sent, the sending of the film is completed.

In the film fast-forward mode (P4), the cam plate 238 is moved by the groove cam 283 to the position shown by the two-dot chain line in FIG. Accordingly, the swinging gear mechanism 228 moves so that the swinging gear 235A meshes with the gear 246A or 247A according to the rotation direction of the reel motor 227, and moves the supply reel 209 in the CW direction or the take-up reel 204 in the CCW direction. It becomes possible to rotate at high speed.

In the film fast-forward mode (P4), the supply reel 209 and the take-up reel 204 are soft-braked by the brake arms 291 and 292, respectively. The reason why the soft braking is applied to the take-up reel 204 in addition to the supply reel 209 is to prevent the film from becoming loose when the swing gear mechanism 228 swings.

As shown in FIG. 39, when the rotation angle of the groove cam 283 is in the rotation range of 140 ° to 175 ° and in the rotation range of 205 ° to 240 °, the soft brake is applied and the rotation of 175 ° to 205 ° is performed. Cam surfaces 285 and 28 for braking so that full braking is applied when
6 are formed. The film is also fed in the fast-forward mode when the film is fed in the forward direction, but is stopped immediately when the next frame is detected by the frame detector at the time of the frame feed.

Scan feed mode (+ X scan) (P
In 5), the cam plate 238 is formed by the groove cam 283 in FIG.
Is moved to a substantially intermediate position between the position indicated by the solid line and the position indicated by the two-dot chain line. Thereby, the swinging gear mechanism 229
Is the swinging gear 2 according to the rotation direction of the reel motor 227.
35B moves so as to mesh with the gear 246B or 247B, and the supply reel 209 can be rotated in the CW direction or the take-up reel 204 can be rotated at a low speed in the CCW direction. The supply reel 209 and the take-up reel 204 are both soft-brake in the same manner as in the film fast-forward mode.

At the stop position (P6), the supply reel 209
And the take-up reel 204 are both fully braked. In the scan feed mode (-X scan) (P7), the cam plate 238 is moved to the same position as in the scan feed mode (+ X scan) (P5), and both the supply reel 209 and the take-up reel 204 are soft-braked. In the film rewind mode (P8), the cam plate 238 is moved to the same position as in the film fast-forward mode (P4), and the supply reel 209 and the take-up reel 204 are both soft-brake. [Frame Feed Control and Film Feed Speed Control] As shown in FIG. 40, a frame detector consisting of a detection lever 270 and a micro switch 271 detects a notch formed on the film, as shown in FIG. (Until the detection lever 270 falls into the notch and the microswitch 271 is turned from ON to OFF) by feeding the film in the forward or reverse direction. Immediately after the frame advance, the optical axis of the taking lens is located at the center of the frame.

On the other hand, after the frame feed, the X-direction scan is performed by film feed. The X-direction scan range is the maximum film movement range in which the minimum zoom area 300 does not protrude from the left end or the right end of the frame. FIG. 40 shows a case where the film is moved in the reverse direction (−X scan) and the minimum zoom area 300 is at the left end of the frame. The distance between the scan position and the frame center at this time is n
Also, assuming that a half width of the minimum zoom area 300 is α, the maximum value of n + α indicates a half width of one frame.

Now, if frame advance is performed in the forward direction from the scan position shown in FIG. 40, the same frame is reproduced again because the frame detector detects the notch of the same frame, and the next frame cannot be reproduced. Occurs. FIG. 41 is a block diagram of a frame feed control device which solves the above problem. This frame feed control device mainly includes a frame detector, a scan position detector, and a control unit 301.

The controller 301 receives a frame detection signal from the micro switch 271 of the frame detector,
A scan position signal (count value (X)) is added from a counter 281 of the scan position detector (see FIG. 37). When the control unit 301 receives the frame detection signal,
The count value of the counter 281 is reset to zero. After activating the reel motor 227, the control unit 301 determines the next frame based on the count value (X) of the counter 281 and the frame detection signal from the frame detector, and stops the reel motor 227.

Next, the operation of the control unit 301 will be described with reference to FIG.
This will be described with reference to the flowchart shown in FIG. First,
The reel motor 227 is activated to feed the frame, and the count value (X) is input from the counter 281 of the scan position detector (steps 303 and 304). Then, the absolute value | X | of the input count value (X) is | X |
It is determined whether or not |> n + α (step 305). ｜ X
If |> n + α is not satisfied, the count value (X) is input again after a short time, and the process is repeatedly executed until | X |> n + α is satisfied.

If | X |> n + α is satisfied, then the frame detector detects whether or not a frame has been detected (microswitch 2).
It is determined whether or not a frame detection signal has been input from step 71 (step 306). That is, the presence / absence of the frame detection signal from the frame detector is ignored until | X |> n + α is satisfied. When | X |> n + α is satisfied, the frame detection signal is input from the frame detector thereafter. Is determined. Thus, after satisfying | X |> n + α, the frame detection signal input first is obtained when the detection lever 270 falls into the notch of the next frame.

As soon as the frame detector detects a frame in step 306, the count value (X) of the counter 281 is set to 0.
And the reel motor 227 is stopped, and the frame feed is terminated (steps 307 and 308).
FIG. 43 is a flowchart showing another embodiment of the frame feed control. As shown in the figure, first, the reel motor 227 is started to advance the frame, and the count value (X) is input from the counter 281 of the scan position detector (steps 309 and 310). Then, it is determined whether or not the input count value (X) is X = 0 (step 311).

When X = 0, the detection lever 270 is in a state of being lowered into the notch. In this case, the process proceeds to step 315. In step 315, after starting frame advance,
It is determined whether the notch has been detected once or not. If the notch has been detected once, the reel motor 227 is stopped, and the frame feed ends (step 317). If X = 0, X> 0
It is determined whether or not this is the case (step 312). If X> 0, it is determined whether or not frame advance is performed in the forward direction (step 31).
3) In the case of frame feed in the forward direction, after detecting the notch once in step 315, the reel motor 227 is stopped and the frame feed is finished (step 317). If the frame is to be fed in the reverse direction, the process proceeds to step 316. In step 316, it is determined whether or not the notch is detected twice after the start of the frame feed.
7 is stopped, and the frame feed ends (step 317).

On the other hand, if it is determined in step 312 that X> 0 is not satisfied, it is determined whether or not frame advance is performed in the forward direction (step 314).
After detecting the notch twice in step 6, the reel motor 227 is stopped, and the frame feed is completed (step 317). In the case of the frame feed in the reverse direction, after detecting the notch once in step 315, the reel motor 227 is stopped, and the frame feed is finished (step 317).

The control for reliably feeding the next frame is not limited to the above-described embodiment. When the film is moved to a position in the forward direction from the frame detection position and the frame is fed in the reverse direction, and when the film is moved to the next frame, In the case of moving to a position in the reverse direction from the detection position and performing frame advance in the forward direction, the count value (X) of the scan position detector becomes the position where X = 0 or X =
After moving by a predetermined amount from the position where it becomes 0, the frame detection signal from the frame detector may be received. That is,
In the above case, the frame detection signal from the frame detector is ignored until the film returns to the reference position (X = 0), so that the frame detector does not detect the same frame.

Next, a case where the film feed speed is controlled to be constant will be described. As described with reference to FIG. 9, the film information recording / reproducing unit 144 transmits the film information (for example, zoom information, scan position information, CCD rotation information, etc.) to the magnetic recording surface of each frame of the film 124 from the control unit 132. The information is recorded by a signal, and the film information is read from the film 124 and output to the control unit 132, and is used for performing automatic reproduction based on the film information. As described above, in order to record film information on the magnetic recording surface of the film and reproduce the film information from the magnetic recording surface, it is necessary to control the film feed speed during recording and reproduction to be constant. On the other hand, if the take-up speed of the take-up reel 204 is controlled to be constant, the film feed speed changes in accordance with the take-up diameter, and becomes lower at the beginning of the film and becomes higher as the end of the film approaches.

FIG. 44 is a block diagram of a film feed speed control device which solves the above problem. This film feed speed control device mainly comprises a frame detector, a frame number calculation section 318A, and a control section 318B. A frame detection signal is applied to the frame number calculation unit 318A from the micro switch 271 of the frame detector. The frame number calculation unit 318A calculates the frame number of the currently reproduced film image based on the frame detection signal applied from the microswitch 271. That is, the frame number calculating section 318A is a counter for counting the frame detection signal. When the beginning of the film is detected, the count value is reset to 0, and then the film is moved in the forward direction (+ X
When a frame detection signal is input during feeding in the direction (), the count value is counted up and the film moves in the reverse direction (-X direction).
When a frame detection signal is input during feeding, the count value is counted down.

The control section 318B has a frame number calculation section 318.
A count value (a value indicating the frame number of the film) is added from A. The control unit 318B outputs a drive voltage corresponding to the frame number of the film currently being wound to the reel motor 227 as shown in the graph of FIG. 45 in order to control the film feed speed to be constant, and controls the winding shaft 204A. Rotate. That is, since the thickness of the film is constant, the winding diameter of the film on the winding shaft 204A has a fixed relationship with the frame number, and the current winding diameter can be inferred from the frame number. Accordingly, the control unit 318B obtains the drive voltage of the reel motor 227 from the current frame number based on the table or calculation formula of the frame number and the drive voltage having the relationship shown in the graph of FIG. , The film feed speed can be controlled to be constant.

The number of perforations from the beginning of the film may be counted instead of the frame number, and the driving voltage to the reel motor 227 may be controlled according to the perforations. Further, the winding diameter may be directly detected by the film winding diameter detecting means, and the drive voltage to the reel motor 227 may be controlled according to the detected winding diameter. This film winding diameter detecting means can be constituted by, for example, an angle detecting means for detecting the rotation angle of the arm plate 276 in the scan position detector shown in FIG. [Search Mode] FIG. 46 is a flowchart showing the search mode. Here, the search mode is
In this mode, the film is fed at the same speed as the film feed speed in the film rewind mode or the film fast-forward mode, but is stopped for a predetermined time for each frame so that a desired film image can be quickly selected.

When the search mode is selected by the selection means (not shown), the film feed is executed by the search mode while the fast-forward switch SW-FF or the rewind switch SW-REW is kept pressed.
When the search mode is selected, the frame feed direction is determined as shown in FIG. 46 (step 319A). That is, when the fast-forward switch SW-FF is pressed, it is determined that the frame is forward in the forward direction, and when the rewind switch SW-REW is pressed, it is determined that the frame is forward in the reverse direction (steps 319B and 319C). Then, it is determined whether or not the frame is advanced in the determined frame feed direction (step 319D). For example, if the currently detected frame is the last frame and the frame advance direction is forward, or if the currently detected frame is the first frame and the frame advance direction is reverse, Since the next frame cannot be advanced, the process returns to the beginning after performing the limit display (steps 319E and 319F).

On the other hand, when the next frame is advanced, the control of the zoom lens is started so as to be in the standard reproduction state (step 319G), and the groove cam 283 is moved to the position in the film fast-forward mode according to the frame feed direction. P4 or to the film rewind mode position P8 (step 3).
19H), and waits until the photographing magnification of the zoom lens becomes the standard magnification (step 319I). When the photographing magnification of the zoom lens reaches the standard magnification, the reel motor is rotated (step 319J), and after elapse of 400 ms (step 319).
At K), frame detection by the frame detector is enabled, and the process waits for the next frame to be detected (step 319L). The reason why the frame detection by the frame detector is enabled after waiting for 400 ms after the rotation of the reel motor is started is to prevent the same frame from being detected.

When the next frame is detected, the reverse rotation brake is applied to the reel motor (step 319M), and the frame number is updated and displayed (step 319N). continue,
A key scan is performed (Step 319P), and Step 3
Stop switch SW-STOP, + X scan switch SW-FWD, -X scan switch SW in 19Q
When it is determined that any one of -REV is ON or none of the switches is ON,
Proceeding to step 319V, the groove cam 283 is moved to the stop position P6.
Then, the process returns to the beginning (step 319W).

On the other hand, at step 319Q, it is determined that the fast-forward switch SW-FF or the rewind switch SW-REW is ON, and furthermore, at step 319R.
When it is determined that the switches in the same direction are kept ON in the step (i), it is determined whether or not a predetermined time has elapsed since the reel motor was stopped (step 319).
S).

Here, the fixed time is a stop time of the reel motor, and is an appropriate time from 0.1 second to 0.5 second. That is, if the stop time is shorter than 0.1 second, it becomes difficult to visually recognize what kind of film image is being reproduced on the video monitor,
If the time is longer than 0.5 seconds, there is a problem that the search time becomes too long. Therefore, the stop time within the above range is set.

If it is determined in step 319S that the predetermined time has not elapsed, the processing from step 319P to step 319S is repeatedly executed until the predetermined time has elapsed, and after the predetermined time has elapsed, the flow proceeds to step 319T.
In step 319T, it is determined whether or not to advance to the next frame, as in step 319D described above. If so, the process returns to step 319J, and the reel motor is rotated again to advance the frame as described above. On the other hand, if it is not possible to proceed to the next frame, the limit display is performed (step 3).
19U), proceed to step 319V, move the groove cam 283 to the stop position P6, and then return to the beginning (step 31).
9W). [Negative / Positive Switching Control] FIG. 47 shows an embodiment of a negative / positive switching control device. Note that parts common to those in FIG. 11 are denoted by the same reference numerals, and detailed description thereof will be omitted.

In FIG. 47, the negative / positive switching control device mainly comprises a light projecting means 320, a light receiving means 321, a negative / positive judging section 322, and an image signal processing circuit 323. The light projecting means 320 includes a light source 320A and a condenser lens 320B as shown in FIG. 48, and the light receiving means 321 includes a pinhole 321A and a photomultiplier 321B.
It is composed of The pinhole 321A is shown in FIG.
As shown in FIG. 49 which is a cross-sectional view taken along the line 49-49, the light from the light projecting means 320 has an opening 321C for transmitting the film edge outside the film perforation, and passes through the opening 321C. Light to the photomultiplier 321B.

The photomultiplier 321B has a sensitivity in the visible range, and outputs a voltage signal corresponding to the amount of light transmitted through the film edge to the negative / positive determination unit 322. The negative / positive determination unit 322 includes a comparator that compares the input voltage signal with a threshold that is a reference for the negative / positive determination. When the voltage signal is greater than the threshold, the negative / positive determination unit 322 outputs a high-level signal indicating that the film is a negative film. Is smaller than the threshold value, a low-level signal indicating a positive film is output.

That is, in the case of a negative film, the film edge portion is transparent orange, the amount of light passing through the film edge portion and incident on the photomultiplier 321B is large, and the output voltage of the photomultiplier 321B is equal to Becomes larger than the threshold. On the other hand, in the case of a positive film, the film edge portion is black, the amount of light transmitted through the film edge portion and incident on the photomultiplier 321B is small, and the output voltage of the photomultiplier 321B is smaller than the threshold.

The image signal processing circuit 323 has a function of performing a negative image processing on the image signal applied from the CCD 116 and a function of performing a positive image processing. When a signal indicating a film (high level signal) is input, negative image processing is automatically performed on the image signal applied from the CCD 116, and a signal (low level signal) indicating a positive film is input. Then, the CCD 11
The positive image processing is automatically performed on the image signal added from step 6. The image signal processed in this way is output to the video monitor 119, and a normal image is reproduced regardless of whether the film currently being photographed is a negative film or a positive film.

FIG. 50 shows the light projecting means 320 shown in FIG.
And another embodiment of the light receiving means 321 is shown. That is,
In FIG. 50, a GaP light emitting diode (GaP-LED) 324 is used as the light projecting means, and a silicon photodiode (SPD) 325 is used as the light receiving means. The GaP-LED 324 has an emission wavelength of 5
SPD 325 has a spectral characteristic of 320 nm
730 nm (peak 560 ± 20 nm).

The light from the GaP-LED 324 passes through the film edge outside the perforation of the film and enters the SPD 325. Also,
When a transparent portion (notch for detecting a frame) is formed on the film edge portion and the transparent portion is located on the optical path, light from the GaP-LED 324 passes through the transparent portion to the SPD 325. Incident.

Table 1 shows GaP-LED 324 and SPD32.
5, the density, the transmitted light ratio, and the SPD 32 when the transparent portion, the negative film, and the positive film are located on the optical path

[0167]

[Table 1] As shown in the table, a negative film and a positive film can be determined based on the output voltage of the SPD 325, and
It is possible to detect a missing portion (frame detection). still,
Although the SPD 325 has temperature dependency, the problem with the temperature dependency of the SPD 325 can be solved by performing calibration with the output of the unexposed portion.

FIG. 51A shows two spools (2
FIG. 51 (B) is a perspective view of a film cartridge having one spool (one shaft). In any of the film cartridges, it is possible to determine whether the film stored in the film cartridge is a negative film or a positive film from the difference in the form of the film cartridge.

For example, a film cartridge containing a negative film has one notch formed on the film cartridge as shown in FIG. 52A, and a film cartridge containing a positive film has a notch shown in FIG. 52B. As shown, two notches are formed in the film cartridge, and two switches for detecting the presence or absence of the notch are provided in the cartridge mounting portion. Then, when the film cartridge is mounted on the cartridge mounting section,
If two switches detect notches, respectively, it is determined that the film is a positive film, and if only one switch detects a notch, it is determined that the film is a negative film. [Image Output Control to Video Monitor] FIG. 53 shows an embodiment of an image output control device to the video monitor. Note that FIG.
The same reference numerals are given to the same parts as those described above, and the detailed description thereof will be omitted.

Referring to FIG. 53, the image output control device for the video monitor sets the film 12 in the photographing area of the photographing lens 114.
4 is not set, a preset image is displayed on the video monitor 119, and mainly includes a film detection unit 326, a control unit 327, and a setting image memory 3
28 and a switching unit 329. The film detection unit 326 detects whether or not the film 124 is set in the photographing area of the photographing lens 114.
As the film detector 326, for example, the film front end detector and / or the film rear end detector shown in FIG. 36 can be applied. That is, the micro switches 273 and 275 of the film front end detector and the film rear end detector
When either of them is ON or both are ON, it can be detected that the film 124 is set in the photographing area.

A signal indicating the presence or absence of a film from the film detection section 326 is applied to the control section 327. The control unit 327 performs the various controls described in FIG. 9 and switches the switching unit 329 according to the presence or absence of the film. That is, when the control unit 327 inputs a signal indicating that there is no film from the film detection unit 326, the image signal processing circuit 117
The image signal from the setting image memory 328 is output to the video monitor 119 in place of the image signal from.

Here, the setting image memory 328 stores in advance setting images that are clearly different from the film image, such as a warning (NO FILM, etc.), a logo mark, a geometric pattern, and an image signal of one color (all blue, etc.). It is remembered. According to the image output control device having the above configuration, when the film 124 is not set in the shooting area of the shooting lens 114, the set image is displayed on the video monitor 119. This makes it possible to immediately determine whether or not the film is set from the display image on the video monitor 119. [Film Discoloration Correction] In the case of automatically performing color fading correction of a negative film or a positive film, it is necessary to know how the film is discolored. Therefore, when a negative film or a positive film is manufactured, a standard pattern for fading correction is burned in advance.

As shown in FIG. 54, in the case of a 35 mm film, the film edges of 5 mm at both ends of the film are not exposed. Therefore, a standard pattern 330 for fading correction is burned into this film edge in advance. Standard pattern 3
As for 30, a gradation pattern of about 10 gradations of RGB is appropriate. FIG. 55 shows a standard pattern in which one of RGB colors is printed at 10 gradations.

FIG. 56 shows a system for printing a standard pattern 330 for fading correction in the process of processing from the film roll 342. As shown in the drawing, the film supplied from the film roll 342 is divided into a predetermined width by a slitter 343, and a perforator is perforated by a perforator 344. Thereafter, the frame number and the standard pattern 330 for fading correction are printed by the printing drum 345.

FIG. 57 shows the standard pattern 3 for fading correction.
It is a figure which shows the detail of 30 burning devices. The burning device includes red, blue, and green light emitting diodes D1, D2, and D3.
, A diffusion plate 346, and a gradation transmission filter 347, and are disposed inside the circumference of the drum 345. At the same time as the frame number is imprinted, the light emitting diodes D1, D2, and D3 are made to emit light, and the standard pattern 330 for fading correction is imprinted on the edge of the film via the diffusion plate 346 and the gradation transmission filter 347.

The film on which the frame number and the standard pattern 330 have been printed in this way is wound on a patrone 348, wound up by a predetermined amount, and cut by a cutter 349. When a film image is reproduced on a video monitor by the film image input device, the degree of fading can be determined by reading the standard pattern 330 and comparing it with data when there is no fading. Then, by correcting the image signal in accordance with the degree of fading, fading correction can be performed. still,
In FIG. 55, the fading is shown by a dotted line. As shown in FIG. 55, the higher the density, the greater the degree of fading.

FIG. 58 shows an embodiment of a film fading correction device. As shown in the figure, the fading correction device mainly includes a reading unit 331, a fading determination unit 332, and a look-up table (LUT) 333. The reading unit 331 reads the standard pattern 330 for fading correction, which is burned in advance on the film edge portion, and uses the read data of the standard pattern 330 as the fading detecting unit 3.
32. The fading determination unit 332 has data when there is no fading, compares this data with the data of the standard pattern 330 input from the reading unit 331, and determines the degree of fading of the film based on the comparison result.

The LUT 333 has a plurality of correction tables corresponding to the degree of fading. An RGB correction table corresponding to the degree of fading is provided by a signal indicating the degree of fading of each of RGB added from the fading determination unit 332. Γ correction circuit 33 in the image signal processing circuit.
4, 335 and 336. γ correction circuits 334, 3
Reference numerals 35 and 336 are provided between a white balance (WB) adjustment circuit in the image signal processing circuit and the matrix and encoder circuit 341. The WB adjustment circuit includes amplifiers 337, 338, and 339 and a WB processing unit 340, and the WB processing unit 340 controls the amplifiers 337 and 339.
The white balance of the R signal, the G signal, and the B signal is adjusted by adjusting the gains of the R, G, and B signals.

The gamma correction circuits 334, 335, and 336 perform gamma correction and color fading correction on the R, G, and B signals that have been subjected to white balance adjustment in accordance with the RGB correction table from the LUT 333. That is, the gamma correction circuit normally raises the sensitivity to a halftone signal as shown by the solid line graph in FIG. 59, but the gamma correction circuits 334, 335, and 336 use the LUT
According to the RGB correction table from 333, for example, as shown in the graph of the two-dot chain line or the one-dot chain line, the sensitivity of a signal having a high density is increased, thereby performing the fading correction at the same time (see FIG. 55).

In this embodiment, the fading correction is also performed by the gamma correction circuit. However, the fading correction may be performed by a correction circuit different from the gamma correction circuit. However, in this case,
The gamma correction component is not included in the RGB correction table.
Further, the standard pattern 330 for fading correction is not limited to the time of film production, and may be imprinted in the margin of the film when the film is developed. According to this,
There is a merit that the latent image regression of the standard pattern exposed in advance does not occur. Furthermore, the region where the standard pattern is printed is not limited to the film edge portion, but may be the terminal portion of the film that is not drawn out of the cartridge as shown in FIG.

[0181]

As described above, according to the present invention, the still photo film is guided by being curved by the film guide members provided on the entrance side and the exit side of the imaging area. The flatness of the film can be obtained without applying a large tension, and the focus of the photographing lens can be adjusted over the entire imaging area. Further, since the developed still photographic film fed by the film feeding means is guided by at least a guide roller which comes into contact with the film image surface, it is possible to prevent a streak-like scratch on the film during the film feeding. Can be prevented.
