The image pickup device 23 includes, for example, three CCDs (Charge Coupled Dev) equipped with R, G, B color filters.
ice) line image sensors are arranged in parallel at right angles to the sensor axis and are composed of color image sensors. The image pickup device 23 (hereinafter referred to as the CCD line sensor 23) is arranged with the sensor axis aligned with the width direction of the projected film image (direction perpendicular to the feeding direction of the film 10). Each film image is picked up by relatively scanning the film 10 in the feeding direction.

The above CCD line image sensor has a photosensitive portion for converting (photoelectrically converting) an optical image into an electric signal image by accumulating an electric charge amount proportional to the incident light amount, and for taking out electric charges accumulated in the photosensitive portion. A transfer unit for retracting the accumulated charges from the photosensitive unit and a discharge unit for discharging unnecessary charges accumulated in the photosensitive unit are provided.

The CCD line sensor 23 accumulates (images) electric charges in accordance with the amount of incident light by the photosensitive portion and transfers the accumulated electric charges to the transfer portion at a predetermined cycle, and then the image processing circuit (see FIG. 1) in the subsequent stage. Output as a captured image. The CCD line sensor 23 alternately repeats the charge accumulation and the transfer of the accumulated charges a plurality of times while scanning the film image, and captures the film image line by line.

FIG. 6 is a waveform diagram for explaining the image pickup operation of the CCD line sensor 23. FIG. 6A is a waveform diagram of a transfer pulse for controlling the transfer of the charge accumulated in the photosensitive section to the transfer section. 7B is a waveform diagram of a reset pulse for controlling the discharge of unnecessary charges accumulated in the photosensitive portion, and FIG. 9C is a waveform diagram of the accumulated charge level accumulated in the photosensitive portion.

The CCD line sensor 23 is a CC which will be described later.
When the imaging start signal is input from the D driver 41 (see FIG. 1), the imaging operation is started, and when the imaging stop signal is input, the imaging operation is stopped. When the imaging operation is started,
A charge corresponding to the amount of incident light is accumulated in the photosensitive section. The accumulated charges are transferred to the transfer unit based on the transfer pulse Pt input from the CCD driver 41 in a predetermined cycle τ, output to the image processing circuit as an image signal, and discharged based on the reset pulse Pr.

The reset pulse Pr is delayed from the transfer pulse Pt by a phase φ, and the reset pulse Pt is set after the accumulated charge is taken out as an image signal by the transfer pulse Pt.
The charges accumulated in the photosensitive portion while r is input are discharged as unnecessary charges. The CCD line sensor 2 is controlled by controlling the output timing (phase φ) of the reset pulse Pr with respect to the transfer pulse Pt.
The exposure period of 3 (corresponding to the shutter speed Tv) is controlled.

For example, time t when the transfer pulse Pt is input
Describing between 0 and t2, when the accumulated charge is extracted as an image signal at time t0, a new charge according to the incident light amount is accumulated in the photosensitive portion, and the accumulated charge level of the photosensitive portion is proportional to the accumulated charge amount. Rise. The rising gradient θ of the accumulated charge level is proportional to the intensity of incident light, and the higher the intensity, the larger the rising gradient θ.

When the reset pulse Pr is input at the time t1 which is delayed by the phase φ from the time t0, the charge accumulated between the time t0 and the time t1 (FIG. 6 (c), the area surrounded by the small triangle). (Corresponding to S1) is discharged as unnecessary charges, and new charges are accumulated in the photosensitive portion from time t1. Then, when the next transfer pulse Pt is input at time t2 after the lapse of a predetermined period τ from time t0, the transfer pulse Pt is input from time t1 to time t2.
The electric charge accumulated in the space (FIG. 6C, which corresponds to the area S2 of the portion surrounded by the large triangle) is transferred to the transfer unit and taken out as an image signal.

Therefore, of the light receiving period τ between the time t0 and the time t2 in the photosensitive portion, the period Tv (= τ-φ) between the time t1 and the time t2 becomes the substantial exposure period of the CCD line sensor 23, and the image Is the imaging period. The exposure period Tv corresponds to the shutter speed of a normal camera, and as is apparent from FIG. 6, the exposure period Tv of each film image can be controlled by controlling the phase φ. That is, the larger the phase φ, the shorter the exposure period Tv and the faster the shutter speed.

When capturing a film image, the required exposure amount is controlled by adjusting the aperture value Av of the iris 22 and the exposure period Tv of the CCD line sensor 23 (hereinafter referred to as electronic shutter speed Tv). (The exposure control means is constituted by the iris 22 and the CCD line sensor 23.) However, the film 10 can be moved at a higher speed than at the time of capturing the film image for reproduction, as at the time of capturing the film image for multi-image which will be described later. When scanning, considering the difficulty of setting the aperture value Av of the iris 22 for each film image, the aperture value Av of the iris 22 is fixed, and only the electronic shutter speed Tv is adjusted to expose each film image. The amount is controlled.

That is, when film images are continuously picked up at high speed, the CCD line sensor 23 alone constitutes the exposure control means.

Returning to FIG. 2, the film image reproducing apparatus 1 is
When the film cartridge 9 is loaded in the film loading unit 13, the orange base data, the magnetic recording units 11A, 11B, 12A, and
The information recorded in 12B (hereinafter referred to as magnetic information) and the density information of the film image of each frame F are read. Further, film images of all frames F are captured, the captured images are combined into an image (hereinafter referred to as a multi-image) formed by two-dimensionally arraying in a predetermined array pattern, and the multi-image is displayed on the display screen 3 of the monitor TV 2. It is supposed to be displayed.

That is, the multi-image display and each frame F
The film cartridge 9 stores orange base data, magnetic information, exposure / color correction calculation data, etc. necessary for image pickup and image processing of the film image reproduction.
It is read immediately after loading. In addition, the display of the multi-image is as index information of the film 10,
This is performed after capturing a film image for multi-image as a processing screen for setting the reproduction condition.

7 and 8 show a display example of a multi-image, FIG. 7 shows a display example in which all the film images of 36 frames are collectively displayed, and FIG. 8 shows a film image of 36 frames of 12 frames. The example of a display when it is divided and displayed in units is shown.

In the multi-image shown in FIG. 7, 36 frame film images are combined in an array pattern of 6 rows and 6 columns. The film images G1 to G36 of each frame F correspond to the shooting order, and are (1, 1), (1, 2), ..., (2, 1), (2, 2) in order from the old film image to the new film image. ),
, (6, 5), (6, 6) are arranged.

In the multi-image shown in FIG. 8, 36 film images are composed of three multi-images, and each multi-image is composed of twelve film images in an array pattern of 3 rows and 4 columns. In this display example, the film images of all frames F are displayed by switching and displaying three multi-images.

The size of the array pattern of the multi-image is set to an appropriate size in consideration of the total number of frames and the display size of each frame. Further, in the divided display using a plurality of multi-images, the lines may be scrolled up and down line by line for display.

In the present embodiment, a 36-shot film has been described as an example. However, a multi-image is formed in an appropriate array pattern corresponding to the number of shots by the same method for a film having an arbitrary number of shots. The multi-image is displayed on the display screen 3 of the monitor TV 2.

The density information of the film image of each frame F is as follows:
It is read in order to calculate a proper exposure value (aperture value Av, electronic shutter speed Tv) and a white balance adjustment value (hereinafter referred to as a WB adjustment value) when a film image for reproduction is captured. The density information of the film image of each frame F (hereinafter referred to as exposure / color correction calculation data) is
The density is extracted at a plurality of discrete points in the film image, and in this embodiment, the density is extracted from the picked-up image picked up for the multi-image. Therefore, in this embodiment,
The exposure / color correction calculation data is read at the same time when the film image for multi-image is picked up.

When the eject table 6 in which the film cartridge 9 is mounted is stored in the table storage portion 131, the presence of the film cartridge 9 is detected by the cartridge sensor 14 and the film information by the bar code 94 is detected by the photo reflector 15. Is read. Then, the film feed unit 161 unwinds the film leader unit 10A of the film 10, the leading end of the film leader unit 10A is wound around the take-up roller 163, and loading is automatically performed.

After that, the film 10 is reciprocally moved to read the orange base data, the magnetic information and the exposure / color correction calculation data, and the film image for the multi-image is picked up.

In this embodiment, after the film 10 is loaded, the film 10 is fast-forwarded (first scan) to the final frame F at high speed to read the orange base data and magnetic information, and then the film 10 is transferred to the first frame. By rewinding to F at a semi-high speed (second scan), exposure / color correction calculation data is read and a film image for multi-image is picked up.

The fact that the reading of the magnetic information, the reading of the exposure / color correction calculation data, and the capturing of the film image for the multi-image are performed separately is based on the fact that the proper scanning speeds of the respective films 10 are different. It is a thing.
The above "high speed" and "semi-high speed" are based on the feeding speed of the film 10 at the time of capturing the film image of each frame F during reproduction.

The scanning speed at the time of picking up a film image for a multi-image is set higher than the scanning speed at the time of reproduction in order to display the multi-image as fast as possible. Since each film image in the multi-image is smaller in size than a regular reproduced image and high image quality is not required, all pixel data (C
The data obtained at each pixel forming the CD line sensor 23 is not required. Therefore, in the present embodiment, each film image is skipped (reduced) in the scanning direction to interlace and scan each film image so as to increase the scanning speed at the time of capturing a film image for multi-images. .

In the interlaced scanning, only the line position where the image is to be captured is scanned at the regular scan speed (scan speed for performing normal image pickup), and the other line positions are scanned at high speed. For example, if the first line is the first line, the second line, the third line, ..., The sixth line, the twelfth line, ..., The 6th k (k = 1, 2, ...), which are line positions that are integral multiples of 6. Scanning the film position by scanning only the line position of the line at the regular scanning speed, and jumping at other line positions at high speed without imaging, the scanning speed should be approximately 6 times the scanning speed during playback. You can Then, the size of the captured image in this case is reduced to 1/6 of the original image size.

The proper scanning speed for magnetic information is usually
The scanning speed is higher than the scanning speed at the time of capturing the film image, and can be increased several times as high as the scanning speed at the capturing of the film image for the multi-image. The processing of reading the orange base data, the magnetic information, the exposure / color correction calculation data, and the film image capturing for the multi-image will be described later.

In capturing a film image, the light source 191 of the illumination unit 19 emits light with a predetermined illuminance, and the light image of several lines in the film image has a predetermined light amount and is reflected by the reflection plate 2.
0, the lens system 21, and the iris 22 to project on the CCD line sensor 23. Then, by controlling the imaging operation of the CCD line sensor 23 in synchronization with the film image feeding timing, the CCD line sensor 23 is relatively scanned with respect to the film image, and one film image is captured. .

The gains AG _R and AG _{B of} 63 are the automatic exposure (A
E (Auto Exposure) / White Balance (AWB (A
Auto White Balance)) Arithmetic circuit 42 (hereinafter AE / A)
It is operated by the WB operation circuit 42) and is input to the WB circuit 26 in synchronization with the input of the image signal to the WB circuit 26.

The A / D converter 27 converts the analog image signal into a digital image signal (hereinafter referred to as image data).
It is a circuit to convert to. The A / D converter 27 is also R,
It is composed of three A / D converters for G and B image signals.

The dynamic range of each A / D converter in the A / D converter 27 is determined by the loaded film 10
It is set by the AE / AWB arithmetic circuit 42 according to the density characteristic of That is, the AE / AWB arithmetic circuit 42
Is an orange-based imaging unit 1 of the loaded film 10.
The dynamic range of the A / D converter for each color of R, G, B is calculated based on the orange base data obtained by imaging 0E, and the dynamic range of each A / D converter is set based on the calculation result. .

The R, G, and B color transmittance characteristics of the film vary depending on the type of the film and the developing conditions, and there are variations within a certain range. When the range of the signal level that can be processed by the A / D converter 27 (density range) is fixedly set, signal processing can be performed without saturating the signal level of the image signal obtained by capturing an arbitrary film. In order to achieve this, it is necessary to set the above-mentioned density range considerably wider than the density range of the actual film image in consideration of variations in the transmittance characteristics of the film.

However, if the density range that can be processed by the A / D converter 27 is fixedly set, when the density range of the actually loaded film is narrow, the density range that can be processed by the A / D converter 27 is reduced. Since the density range of the image signal of the captured image becomes extremely narrow, the resolution of the image signal becomes relatively coarse, and it becomes difficult to process the image signal with high accuracy.

FIG. 9 is a diagram showing the red transmittance (density) characteristic of the color film with respect to the exposure value.

The transmittance characteristic shown by the solid line in FIG. 9 shows the case where the density range is the narrowest, and the transmittance characteristic shown by the dotted line shows the case where the density range is the widest. The difference ΔD between the density ranges of the two transmittance characteristics is the density range variation.

When the dynamic range of the A / D converter 27 is fixedly set, considering the variation in the density range of the film, the upper limit of the density range that can be processed by the A / D converter for a red image signal is the density range. It is necessary to set the transmittance P1 (> P1 '(%)) obtained by adding a margin to the upper limit (P1' (%)) of the widest transmittance characteristic of the above.

In this case, if the loaded film 10 has, for example, the transmittance characteristic, the A / D converter can process the density range (0 to P2 '(%)) of the actual image signal. That is, the density range becomes too wide, and the processing accuracy with respect to the actual image signal decreases.

That is, for the film 10 having the transmittance characteristic, the density range that can be processed by the A / D converter with respect to the red image signal is sufficient even though the transmittance P2 is slightly higher than the transmittance P2 '. The presence of the transmittance range ΔR (= P1−P2) that does not actually exist narrows the signal processing range by this amount (in the figure, P2 / P1 = compressed to approximately 80%), and relatively. The resolution of the level of the red image signal is reduced.

In this embodiment, the orange base data of the film 10 (data of the maximum transmittance of the film) is taken in before the film image is picked up, and the A / D converter 27 can process based on the orange base data. The density range is set.

Accordingly, the processable density range of the A / D converter for the red image signal is the orange base data P2 '(%) when the loaded film 10 has, for example, the transmittance characteristic. Based on the film 1
0-P2 density range required for image signal processing of a captured image of 0
If it is set to (%) and has a transmittance characteristic, for example, the density range 0 to P1 (%) necessary for image signal processing of the picked-up image of the film 10 is based on the orange base data P1 ′ (%). It is set to the range of.

The same applies to the G and B color components of the film, and the density range that can be processed by the A / D converter with respect to the G and B color image signals is appropriate based on the orange base data. Set to range.
As a result, regardless of the variation in the density range of each color of R, G, B between the films and the variation of the balance of the color components of R, G, B between the films, an appropriate density range can be obtained according to the density range of the film image. Image processing of a picked-up image can be suitably performed.

Returning to FIG. 1, each of the R, G, and B image data output from the A / D converter 27 is stored in the γ correction circuit 28.

The horizontal dimension L ′ of the captured image is set to the horizontal dimension of the display size in the multi-image by controlling the.

The reduced picked-up image is subjected to predetermined signal processing by the CDS circuit 24 to the γ correction circuit 28, and is then subjected to a thinning process of image data in the vertical direction (width direction) to obtain the first image. It is stored in the memory 29. By this thinning-out process, as shown in FIG.
The captured image reduced in the vertical direction is stored.

The vertical reduction ratio is the vertical dimension H of the reproduced image.

As a method of taking a picture, a film is wound on the camera one by one each time a picture is taken, and a picture is taken in order from the top of the film in the backward direction (hereinafter referred to as a normal wind method). Once the film is loaded, the film is once wound to the final frame position, and each time a photo is taken, the film is rewound one frame at a time and the photo is taken in order from the last frame of the film in the forward direction. , Pre-wind method).

FIGS. 11 and 12 are views showing the appearance of the developed film after taking 36 sheets. FIG. 11 is an appearance view when the image is taken by the normal wind method, and FIG. 12 is taken by the prewind method. FIG.

As is apparent from FIGS. 11 and 12, the film recorded by the normal wind method (hereinafter referred to as the forward direction film) has the oldest film image G1 recorded on the first frame F of the film 10 and the last frame. The newest film image G36 is recorded in F. In the pre-wind filmed film (hereinafter, referred to as reverse photographic film), the newest film image G36 is recorded on the leading frame F of the film 10, and the oldest film image G1 is recorded on the final frame F.

The type of the film is discriminated from the magnetic information read from the film 10 by the system controller 44. For example, when the information about the film type is directly recorded in the magnetic recording units 11A and 11B of the film reader unit 10A, it is determined from the magnetic information, and when the information about the film type is not directly recorded, each frame is recorded. Magnetic recording parts 12A and 12B corresponding to F

Since the reading control of the magnetic information and the like differs depending on whether the film 10 loaded in the film image reproducing apparatus 1 is a forward-direction photographic film or a backward-direction photographic film, the following is the reverse of the case of the forward-direction photographic film. The description will be made separately for the case of the direction photographing film.

When the film cartridge 9 is loaded in the film loading section 13, the film 10 is automatically loaded and subsequently fed to the film end section 10C. The film 10 is accelerated to a predetermined speed (high speed) after the loading is completed, and the orange base data is read during this acceleration period. In addition, the image capturing unit 10B scans in the winding direction at the high speed (first scan).
Then, the magnetic information is read in this first scan.

When the film 10 reaches the film end portion 10C, its feeding direction is reversed, and after being accelerated to a predetermined speed (semi-high speed) slower than the first scan,
The image capturing unit 10B is scanned in the rewinding direction (second scan) at this speed, and the exposure / color correction calculation data is read and the film images G36 to G1 for multi-image capturing are performed.

When the film 10 is rewound to the film leader portion 10A, the feeding of the film 10 is stopped. In addition, a predetermined multi-image is generated and the monitor T
They are collectively displayed on the display screen 3 of V2, and the reproduction conditions can be set and the film image can be reproduced.

After that, when the operator sets the reproduction condition of the film image and then the reproduction is instructed, the film image of each frame F is displayed on the monitor TV 2 according to the set reproduction condition.
Is reproduced and displayed on the display screen 3. During this reproduction, the film 10 moves in a winding direction from the leading frame F at a predetermined speed (low speed).
Are sequentially fed, film images of a predetermined frame F are sequentially captured (third scan), and predetermined image processing is performed.

At the time of this rewinding, information such as the reproduction conditions set above (changed contents of magnetic information) is recorded in the magnetic recording unit 1 of the film 10.
1A, 11B, 12A, and 12B are updated and recorded.

Next, with reference to the flow charts of FIGS. 14 and 15, the reading control of the magnetic information and the like of the forward photographing film and the reproduction process of the film image will be described in detail.

FIG. 14 is a flow chart of the reading control of magnetic information and the like of the forward photographing film. When the film cartridge 9 is loaded on the eject table 6 and stored in the film loading unit 13 (# 1), the light source 191 of the illumination unit 19 is turned on (# 3), and then the film 10 is loaded (# 5), display screen 3 of monitor TV 2

After v, the electronic shutter speed Tv, and the WB adjustment value are calculated (# 17), the magnetic information is read from the magnetic recording units 11A and 11B while fast-forwarding the film 10 in the winding direction at high speed (# 19, # 21). ). The type of film is determined from the content of the magnetic information, and the size of the reproduced image of each image is determined (PHL determination) and the vertical / horizontal screen is determined (vertical / horizontal determination).

When the reading of the magnetic information is completed (the first scan is completed) (YES in # 21), the iris 22 is changed to # 17.
The aperture value Av calculated in step 3 is set (# 23), the feeding direction of the film 10 is reversed, and the second scan is started (# 25).

This is because the exposure / color correction calculation data is read and the multi-image film image is picked up at a relatively high speed, so that the aperture value of the iris 22 and the like are set at high speed every time the film image of each frame F is picked up. Considering that it is difficult to set the multi-image and high image quality is not required as compared with the reproduced image, the aperture control of the iris 22 is not performed every time the film image of each frame F is captured. .

Then, while referring to the multi-image displayed on the display screen 3 of the monitor TV2, the operator sets the reproduction conditions such as the reproduction order of each frame F, vertical / horizontal conversion, and clipping (# 39).

This indicates that the multi-image is sequentially displayed on the display screen 3 of the monitor TV 2 each time the film image of each frame F is captured (hereinafter, referred to as multi-image sequential display).

FIG. 22A shows an example of a multi-image stored in the first image memory 29 when the film image of the ninth frame is picked up. The film images of the first frame to the ninth frame are shown. The captured images G1 to G9 are combined into a multi-image in an array pattern of 6 rows and 6 columns.

In the multi-image batch display, all film images of 36 frames are picked up, and a multi-image (see FIG. 11) in which these picked-up images G1 to G36 are combined is displayed on the display screen 3 of the monitor TV2. In multi-image sequential display,
As shown in FIG. 22A, each time a film image of each frame F is captured, a multi-image composed by combining the film images already captured by the capturing time is displayed on the display screen 3 of the monitor TV 2. It

In the case of reverse photographic film, the orange base data and magnetic information are read in the first scan, and the exposure / color correction calculation data and the film image for multi-image are picked up in the second scan. The magnetic information is recorded when the film 10 is rewound at high speed at the end, which is the same as in the case of the forward-direction photographic film, but the multi-image display method is the multi-image sequential display (FIG. 17). (See arrow q3 in FIG. 3), when the second scan is completed, reproduction is possible from the film image G1 of the first frame in the reproduction processing of the film image.
When the film 10 is fast forwarded to the film end portion 10C at a high speed and the reproduction of the film image is completed, the film 10 is transferred to the film end portion 10 to record the magnetic information.
Point to fast-forward to C (white arrow Q in Fig. 17)
3) is different.

Multi-image sequential display is performed on the reverse photographic film because the reverse photographic film captures the film images of each frame F in the order of film images G1, G2, ... This is because the multi-images are generated in this order, so that the multi-images are sequentially displayed on the display screen 3 of the monitor TV 2 to reduce the discomfort in operation.

That is, it takes a relatively long time from the loading of the film cartridge 9 into the film loading section 13 until the reading of the film image for the multi-image and the exposure / color correction calculation data is completed, and during this period, the loading state is displayed. If only this is done, the user feels uncomfortable in operation. Therefore, by switching the loading state display to the multi-image display as early as possible, the above-mentioned uncomfortable feeling in operation is alleviated.

On the other hand, although the multi-image sequential display is possible on the forward direction film, the film image of each frame F is picked up in the order of film images G36, G35, ... Since the multi-images are generated in the order of the first frame, the multi-images displayed on the display screen 3 of the monitor TV 2 become unnatural when the multi-images are sequentially displayed. Therefore, in this embodiment, the multi-images are collectively displayed. There is.

Further, the high-speed fast-forwarding processing indicated by the white arrow Q3 is performed by the film images G1 to G1 of the respective frames F of the backward photographic film.
This is based on the fact that the arrangement direction of G36 is opposite to that of the forward photographing film.

Next, with reference to the flow charts of FIGS. 18 and 19, the reading control of the magnetic information of the reverse photographic film and the reproduction process of the film image will be described.

FIG. 18 is a flow chart of the reading control of the magnetic information and the like of the reverse photographic film. The processing procedure shown in the figure is basically the same as the processing procedure shown in FIG.
~ # 111, # 115, # 117, # 125, # 127
Each process of # 1 to # 31, # 33, # 37, # 39,
It corresponds to each process of # 41. In the flowchart of FIG. 18, based on the above difference, instead of the “multi-image batch display” of # 35, a “multi-image sequential display” process is provided between # 111 and # 115.
14 is different from FIG. 14 in that a fast-forward process for the film 10 is provided between # 123 and # 123.

Therefore, here, the description of the same processing as that in FIG. 14 will be simplified, and the processing relating to the above-mentioned difference will be supplementarily described.

The film 10 of the film cartridge 9 loaded in the film loading section 13 is automatically loaded (# 81 to # 87), and orange base data and magnetic information are read in the first scan (# 89 to # 1).
01). Subsequently, the iris 22 is set to the predetermined aperture value Av calculated in # 97 (# 103), and the film 10
Feed direction is reversed and the second scan is started (#
105).

When the second scan is started, the electronic shutter speed Tv and the WB adjustment value are set to the calculated values calculated in # 97 (# 107), and then the film 10 is rewound at a semi-high speed while the multi-image is reproduced. The exposure / color correction calculation data of each frame F for reading and the film image capturing are started (# 109).

Every time the exposure / color correction calculation data of each frame F is read and the film image is picked up, the aperture value Av, the electronic shutter speed Tv and the WB adjustment value at the time of reproduction are reproduced based on the exposure / color correction calculation data. Is calculated, a multi-image is created from the captured image and is sequentially displayed on the display screen 3 of the monitor TV 2 (# 111 to # 115).

When the exposure / color correction calculation data has been read and the film image for multi-image has been picked up for all frames F (YES in # 115), rewinding of the film 10 is stopped (second scan). End, # 117).

Subsequently, the film 10 is fast forwarded to the film end portion 10C at high speed (# 111, #, 12).
1) After the multi-image display is stopped (# 123), while referring to the multi-image displayed on the display screen 3 of the monitor TV2, the reproduction order of each frame F, vertical / horizontal conversion, and setting of reproduction conditions such as clipping are set. Performed by the operator (# 125).
When the setting of the reproduction condition is completed, the setting condition is recorded in the internal memory of the system controller 44, and the image reading standby state for reproduction is set (# 127).

FIG. 19 is a flow chart of the reproduction processing of the film image of the reverse photographic film.

The processing procedure shown in the figure is basically the same as the processing procedure shown in FIG. 15, and the steps # 129 to # 141 and # 149 to # are performed.
Each process of 159 corresponds to each process of # 45 to # 57 and # 65 to # 75. In the flowchart of FIG. 19, based on the above difference, there is no film fast-forwarding process corresponding to # 59 to # 63, and instead of # 141 and # 149.
It differs from FIG. 15 in that a film fast-forward process is provided between them.

Therefore, here, the description of the same processing as that in FIG. 15 is simplified, and the processing relating to the above-mentioned difference will be supplementarily described.

When the reproduction mode (image capture mode) is set from the operation unit 8 in the image read standby state (# 12
9), the film image of the frame F to be reproduced is picked up while feeding the film 10 in the winding direction at a predetermined low speed, and sequentially reproduced and displayed on the display screen 3 of the monitor TV 2 according to the set effect conditions. Is performed (loop of # 131 to # 139). When the reproduction of the film images of all the frames F to be reproduced is completed (YES in # 139), the feeding of the film 10 is stopped (# 141).

Subsequently, the film 10 is fast-forwarded at high speed (loop of # 143 to # 145), and the film end portion 1
When it reaches 0C, it is stopped (# 147). Then, high-speed rewinding of the film 10 is started (# 149), and the magnetic information recorded in the internal memory of the system controller 44 during the rewinding period is recorded in the magnetic recording section 11A of the film 10.
11B, 12A, and 12B are updated and recorded (# 15
1, # 149 to # 153 loop).

When the film 10 is rewound to the film leader portion 10A (YES in # 153), the feeding of the film 10 is stopped (# 155), and the film 1
0 is stored in the film cartridge 9 (# 15
7), the eject table 6 is ejected from the film loading section 13 (# 159).

If the reproduction mode is not set in # 129 (NO in # 129), the film 10 is fast-forwarded to the film end portion 10C, so that the process proceeds to # 149 and the film 10 is rewound at a high speed and the magnetic Information is updated and recorded in the magnetic recording units 11A, 11B, 12A and 12B (# 149 to # 159).

By the way, in the film image reading process for the multi-image of the reverse photographic film, the multi-image sequential display is performed during the second scan, and the film 10 is transferred to the film end portion 10C after the end of the second scan. During the fast-forwarding period, the multi-image of all frames was displayed (the same as the multi-image batch display).
As shown in FIG. 20, the multi-image sequential display may be performed during the second scan and the fast-forward period of the film 10.

When the multi-image sequential display is performed only during the second scan, the film 10 is moved to the film end portion 1.
Even if the multi-image batch display is performed during the fast-forwarding to 0C, the operator cannot immediately set the playback conditions or perform the playback, which causes a sense of incongruity in the operation, but the multi-image during the fast-forwarding period of the second scan and the film 10. When the sequential display is performed, the next operation can be performed immediately after the display of the multi-image is completed, which is advantageous in eliminating the above-mentioned operational discomfort.

FIG. 21 is a flow chart showing the sequential display of multiple images during the second scan and the fast-forwarding period of the film in the control of reading the magnetic information of the reverse photographic film.

FIG. 21 is a block diagram of # 107 and # in FIG.
A process (# 108) for calculating the display period Ti of each multi-image in the multi-image sequential display is provided between 109 and # 1.
A process (# 112) for instructing the display timing of each multi-image in the second scan period is provided between 11 and # 113, and the display timing of each multi-image in the fast-forward period of the film 10 is instructed between # 119 and # 121. The processing (# 120-1, # 120-2) is performed.

Therefore, here, the description of the same processing as that of FIG. 15 is simplified, and the above-mentioned added processing will be supplementarily described.

The film 10 in the film cartridge 9 loaded in the film loading section 13 is automatically loaded (# 81 to # 87), and the orange base data and magnetic information are read in the first scan (# 91 to # 1).
01). Subsequently, the iris 22 is set to the predetermined aperture value Av calculated in # 97 (# 103), and the film 10
Feed direction is reversed and the second scan is started (#
105).

When the second scan is started, the electronic shutter speed Tv and the WB adjustment value are set to the calculation values calculated in # 97 (# 107). Then, the display period Ti of each multi-image for performing the multi-image sequential display is calculated during the second scan and the fast-forwarding period of the film 10 after the end of the second scan. The second scan period is Ta,
When the period from the end of the second scan to the end of the fast-forwarding of the film 10 is Tp and the total number of frames is Nk, the above display period Ti
Is calculated by Ti = (Ta + Tp) / Nk.

Subsequently, the timer built in the system controller 44 starts counting, and while the film 10 is rewound at a semi-high speed, the exposure / color correction calculation data is read and the film image for the multi-image is picked up. It is started (# 109).

Every time the exposure / color correction calculation data is read and the film image for the multi-image is picked up, the aperture value Av, the electronic shutter speeds Tv and WB at the time of reproduction are reproduced based on the exposure / color correction calculation data. The adjustment value is calculated (# 111), a multi-image is created from the captured image and is sequentially displayed on the display screen 3 of the monitor TV2 (# 1).
09- # 115 loop). At this time, each multi-image is switched and displayed for each display period Ti regardless of the reading timing of the film image of each frame F.

The control of the sequential display of the multi-images is performed by controlling the timing of reading the multi-images from the first image memory 29 to the second image memory 32.

FIG. 22 is a diagram showing an example of a multi-image in the multi-image sequential display. FIG. 22A shows the first image memory 2
9 is a block diagram of the multi-image stored in FIG. 9, and FIG. 9B is a block diagram of the multi-image stored in the second image memory 32.

In the second scan, when the film image of each frame F is picked up, each picked-up image is subjected to a predetermined image signal processing, and then combined into a predetermined array pattern and stored in the first image memory 29. To be done. FIG. 22A shows a multi-image stored in the first image memory 29 when the film image of the ninth frame is picked up, and the film images G1 to G9 are shown.
Are combined in an array pattern of 6 rows and 6 columns.

Each multi-image is displayed on the monitor TV 2 for the display period Ti during the second scanning and the fast-forwarding of the film 10.
The display timing of each multi-image is delayed from the reading timing of the film image of each frame F because it is displayed on the display screen 3. For example, when the film image of the ninth frame is read, if a multi-image composed of the film images G1 to G6 of the first frame to the sixth frame is displayed on the display screen 3 of the monitor TV2, the first image is displayed. Memory 29
The multi-image shown in FIG.
This multi-image is stored in the image memory 32, and this multi-image is displayed on the monitor T.
It is displayed on the display screen 3 of V2.

That is, of the multi-images stored in the first image memory 29, the portions corresponding to the film images G7 to G9 are removed and read out to the second image memory 32 to generate a multi-image to be displayed. It This multi-image generation control is performed by the system controller 44 via the address calculation circuit 43.

Returning to FIG. 21, when the reading of the exposure / color correction calculation data and the film image capturing are completed for all frames F (YES in # 115), the rewinding of the film 10 is stopped (# 117).

Subsequently, the film 10 is fast forwarded at high speed to the film end portion 10C (# 111 to #, 12).
1) In the fast-forward period, the predetermined multi-images are sequentially displayed for each display period Ti (# 120-
1, # 120-2).

When the fast-forwarding of the film 10 is completed (# 1
If YES in step 21, the multi-image sequential display is terminated (#
123). Then, referring to the multi-image displayed on the display screen 3 of the monitor TV2, the reproduction order of each frame F, vertical / horizontal conversion,
The operator sets reproduction conditions such as clipping (# 125). When the setting of the reproduction condition is completed, the setting condition is recorded in the internal memory of the system controller 44, and the image reading standby state for reproduction is set (# 127).

In the reverse photographic film, after the film image reproduction process is completed, the film 10 is fast forwarded to the film end portion 10C at high speed, and then the magnetic information is written while rewinding at high speed. , Magnetic information when the film 10 is fast forwarded (see Q3 in FIGS. 17 and 20) to perform the reproduction processing of the film image after reading the exposure / color correction calculation data and capturing the film image for the multi-image. May be written.

In this case, if the magnetic information writing process is provided between # 143 and # 145 while deleting # 147 to # 155 in the flowchart of FIG. 19, the above process can be performed. This eliminates the need for the fast-forward process for one round trip of the film 10 for the magnetic information writing process, so that the magnetic information writing process can be performed with high efficiency and high-speed processing can be performed. It also has the advantage of being easy to control. In addition, damage caused by scanning the film 10 can be reduced.

[0193]

As described above, according to the present invention,
Each time you take a film image of each frame of developed film,
Since the picked-up image and the picked-up image already picked up are combined into a multi-image formed by arranging in a predetermined arrangement pattern, and the multi-image is sequentially displayed on the display means, the multi-image is read from the start of reading the film image. The time until the image is displayed is short, and the operator is less likely to feel uncomfortable in operation.
