(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 a predetermined period τ has passed from time t0, the time t1 to time t
The electric charge accumulated between the two (FIG. 10 (c), 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 section, the period Tv (= τ-φ) between the time t1 and the time t2 becomes a substantial exposure period of the CCD 23, and a film image is picked up. It will be a period. The exposure period Tv corresponds to the shutter speed of a normal camera, and as is clear from FIG. 10, 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.

ive double sampling circuit, analog amplifier, and signal processing circuit such as white balance (WB) circuit.
The image signal (analog signal) of each color of R, G, B output from the CD 23 is subjected to predetermined signal processing.

In the analog processing section 14, R,
The noise of the image signals of G and B is suppressed by the CDS circuit, and then amplified to a predetermined level by an analog amplifier.
Further, the WB circuit automatically adjusts the white balance of the image signal. The WB circuit includes three amplifiers for R, G, and B image signals, and corrects the levels of the R and B image signals based on the level of the G color image signal.

Further, the film image reproducing apparatus 1 considers the operability of the editing work and the search operation of the reproduction frame, and the film image of all the frames F is two-dimensionally arranged in a predetermined arrangement pattern (hereinafter, referred to as a multi-image). It has a multi-display function of reproducing and displaying on the monitor TV 2 as an image. Since the size of the image of each frame F in the multi-image is smaller than that of the reproduced image, an image capturing process different from the image capturing process in the normal reproducing process is performed in the image capturing for the multi-image.
The captured image data is reduced to a predetermined size by the thinning process and stored in the first image memory 27.

(A) is a figure which shows the original film image, (b) is a figure which shows the image imaged for multiple images, (c) is a figure which shows a reduced image.

In the multi-image pickup, a part of the pixel data (data obtained at each pixel forming the CCD 23) forming the film image is interlaced by scanning the film image. This is because the image of each frame F forming the multi-image is smaller than the normal reproduced image and high image quality is not required, and therefore all pixel data forming the film image is not necessarily required. Is.

In the interlace scanning, only the line position where the image is to be captured is scanned at the scan speed during normal reproduction (hereinafter referred to as the main scan speed), and the other line positions are scanned at a speed higher than the scan speed during normal reproduction. To do. For example, from the first line to the first line, the second line
Lines, 3rd line, ..., Only the line position of the 6k (k = 1,2, ...) line, which is a line position that is an integral multiple of 6, is imaged, and when jumping at high speed, it is possible to capture multiple images. Scan speed of the main scan is about 6 times the main scan speed, and the captured image G ′ is reduced in the feeding direction of the film 11 with respect to the original film image G (see FIG. 11A) (see FIG. 11). (B), see). This reduction ratio (L '/ L) is approximately inversely proportional to the feeding speed of the film 11 and is approximately 1/6.

When the captured image G'is stored in the first image memory 27 from the first process circuit 26, the required reduction ratio (H ') is further applied in the vertical direction (width direction of the film 11).
/ H), the thinning processing of the data forming the captured image G ′ is performed at a predetermined pitch, and the reduced image G ″ is stored in the first image memory 27 as shown in FIG. 11C. .

This is performed by detecting the front end position and the rear end position of each piece F from the detection signal of 6.

The end position of the film 11 is detected by detecting the hole 115 from the detection signal of the photo reflector 16. Specifically, the distance between the hole 114 indicating the leading end position of the film end portion 11C and the hole 115 indicating the trailing end position is smaller than the distance between the hole 111 indicating the leading end position and the hole 112 indicating the trailing end position of each frame F. Since it is short, the scanning time from the leading edge position to the trailing edge position is counted for each frame, and when the scanning time is shorter than the previous scanning time, the hole 115 (the trailing edge position of the film end portion 11C)
Is determined to have been detected. The details of the detection of the end position of the film 11 will be described later.

This timer is controlled by the flowchart of the “APO sequence” shown in FIG. 12, and is for automatically turning off the power switch 801 when the operation relating to the reproduction processing is not performed for a predetermined time or longer.

The "APO sequence" is executed when a certain process based on the instruction from the operation unit 8 is completed, and first, the APO timer 44 starts counting a predetermined time (# 501). When the APO timer 44 finishes counting the predetermined time without operating any switch of the operation panel 101 (YES in # 503), a predetermined end process is performed according to the flowchart of the "end sequence" described later (# 509). ).

If any switch is operated while the APO timer 44 is counting a predetermined time (Y in # 505).
ES), it is determined whether or not this switch operation is performed by the power switch 801 or the eject switch 803 (# 507). If the power switch 801 or the eject switch 803 is operated (YES in # 507). , # 509, and a predetermined ending process is performed. On the other hand, if any switch other than the power switch 801 or the eject switch 803 is operated (#
(NO in 507), after the counting operation of the APO switch 44 is stopped and the count value is reset (# 511), the process proceeds to a predetermined step corresponding to the instruction of the operated switch in the control flowchart, and the instruction is performed. A predetermined process for the content is performed.

Returning to FIG. 4, the power supply section 45 supplies required power to each circuit in the film image reproducing apparatus 1. The power supply unit 45 has a detection circuit that detects the supply of AC power, and when the power plug K3 is connected to an outlet and AC power is supplied, this detection signal is sent to the control unit 47. The control unit 47 causes the power plug K to operate according to the detection signal.
3 recognizes that it has been connected to the outlet, performs a predetermined initialization process, and enters the standby state.

The superimposing section 46 generates superimposing data to be superimposed on the reproduced image. When the character information to be superimposed is input from the control unit 47, the superimposing unit 46 converts the character information into superimposing data, and outputs the superimposing data to the second process unit 30 at a predetermined timing.

The control section (discriminating means) 47 is a control section for centrally controlling the operation of the entire film image reproducing apparatus. The control unit 47 controls the driving of each of the above-mentioned components according to a processing program relating to image pickup / reproduction of a film image, which is stored in advance in a built-in ROM (Read Only Memory).

Next, the reproducing operation of the film image reproducing apparatus according to the present invention will be described with reference to the flowcharts of FIGS. 13 to 34 and the drawings.

13 to 18 are flowcharts of initialization processing (initialization) performed when the power switch 801 of the film image reproducing apparatus 1 is turned on.

When the power plug K3 is inserted into the outlet and AC power is supplied, this is detected (#
1) First, the light source heater 194 is turned on (# 3).
Subsequently, when the power switch 801 is turned on by the operator (# 5), the CCD 23 is preliminarily driven (#
7), the power lamp 802 is turned on (# 9). The pre-driving is performed pre-driving before the original imaging operation is performed in order to suppress the influence of the level fluctuation of the dark output that occurs immediately after the driving of the CCD 23 is started.

The film image reproducing apparatus 1 has a monitor T.
If V2 is connected and the monitor TV2 is already activated, for example, the entire display screen 3 of the monitor TV2 is displayed in a blue background or the like, and the monitor TV2 is also displayed that the power of the film image reproducing apparatus 1 is ON.

Then, the output signal (hereinafter, referred to as dark output data) of each pixel of the CCD 23 at the time of darkness is taken in as correction data of the dark output level of the pixel data forming the picked-up image, and is stored in the AE / AWB arithmetic circuit 39. After being stored in the memory (# 11), the light source 191 emits light (# 13).
The light source 191 automatically emits light after the processes of # 1 to # 11 are completed, but a light source switch (not shown)
Alternatively, the light source switch may be separately provided, and the operation may be performed based on an operation of the operator such as turning on the light source switch.

Subsequently, it is judged whether or not the film cartridge 9 is loaded in the film storage section 10 (# 1
5) If the film cartridge 9 is not loaded (NO in # 15), an unloaded message is output, the eject table 6 is pulled out from the film storage unit 10, the loading port is opened, and the film cartridge 9 is loaded. It will be in a standby state until it is set (# 17 to # 2
1).

The unloaded message is displayed on the display unit 7 for example.
28 in the display area 703 or the monitor TV2 of FIG.
This is performed by blinking the film mark FM shown in (a) or by separately providing an unloaded mark in the display area 703 and turning on the unloaded mark. The unloaded message may be displayed in characters on the display screen 3 of the monitor TV 2, and a voice message such as "Please insert the film cartridge." May be generated from the speaker 4.

Then, when the film cartridge 9 is set in the film storage section 10 (YES in # 21), the compatibility of the film cartridge 9 and the film 11 (whether or not they can be normally reproduced) is determined. Done (#
23, # 29).

The suitability of the film cartridge 9 is, for example, in conformity with the cartridge standard, whether the developed film is stored (whether the alignment mark 93 of the film cartridge 9 is set to "PROCESSED"), and the foreign matter is mixed. It is determined by checking the presence or absence.

If the film cartridge 9 is suitable (YES in # 23), after the film winding is displayed, the film information recorded in the bar code 94 of the film cartridge 9 is read (# 25, # 27), the suitability of the film 11 is judged from the film information (#
29). The suitability of the film 11 is determined by checking the film sensitivity, the film type (negative / positive), the film standard, and the like.

Film cartridge 9 or film 11
If is not compatible (NO in # 23 or # 29), the film cartridge 9 is ejected from the film storage unit 10 (# 31), and the film cartridge 9 or the film 11 is ejected.
Non-conformity message is sent (# 33).

The incompatibility message is caused by blinking the film mark FM (see FIG. 28A) on the display area 703 of the display section 7 or the monitor TV2, for example.
Error codes are displayed in the display areas 704 and 705, or incompatibility marks are separately provided in the display area 703.
This is done by turning on the incompatibility mark. The incompatibility message may be displayed in characters on the display screen 3 of the monitor TV 2, and a voice message such as “This cartridge cannot be reproduced” may be generated from the speaker 4.

Film cartridge 9 and film 11
Is satisfied (YES in # 29), the light-shielding lid 98 of the film cartridge 9 is opened, and the reader section information reading process is performed according to a subroutine “reader section information reading” (# 35, # 37, # 39). The power is turned off with the film cartridge 9 loaded, and when the power is turned on again, if the film cartridge 9 is already loaded, the film 11 is loaded and the light shielding lid 98 is already opened. Therefore, the reading processing of the reader section information is performed without performing the opening processing of the light shielding lid 98 (# 35, # 39).

If the film cartridge 9 is loaded when the power is turned on (YES in # 15), it is determined whether or not the film has been loaded (the film 11 has been pulled out to the image pickup section 11B) (# 41). If it is already loaded (YES in # 41), the film rewinding display is performed, and the feeding motor M is rotated at the high speed in the reverse direction (film 11).
The film 11 is rewound to the end position of the film leader portion 11A (until the hole 113 is detected) (# 43, # 45). The film rewinding display is performed by, for example, the display area 703 of the display unit 7 and the monitor T.
The rewinding mark FR shown in FIG. 28 (c) is displayed on V2.

Subsequently, it is judged whether or not the film information read by the film cartridge 9 at the previous loading of the film 11 is stored in the data memory 43 (# 47), and the film information is stored in the data memory 43. If not (NO in # 47), # 23 to # 39
If the film information reading process is performed by performing the process No. and the film information is already stored in the data memory 43 (YES in # 47), the processes of # 23 to # 39 are not performed (the film information # 4 without reading
9 (see FIG. 14).

Here, the reading process of the reader section information will be described. FIG. 19 is a flowchart of the subroutine "reading reader information".

When the subroutine "reader information read" is called, the low speed forward rotation drive of the feeding motor M (winding of the film 11 at low speed) is started (# 14).
1), the timer T1 in the control unit 47 starts counting the predetermined time t1 (# 143, # 145). The counting of the predetermined time t1 by the timer T1 is for judging whether the loading is good or not depending on whether the loading is completed within the predetermined time.

When the loading detector 35 detects the loading of the film 11 within the predetermined time t1 (YES in # 147), the timer T1 is reset (#
149), the drive of the feeding motor M is stopped (# 15).
1).

Subsequently, after the magnetic heads 18A and 18B are set to the reading position (# 153), the film 11 is rewound at a low speed and the leader section recorded in the magnetic recording sections 116A and 116B of the film reader section 11A. The information is read (# 157, # 159).

That is, the film 11 is exposed to the unexposed area 11
The magnetic information reading control unit 33 reads the reader unit information recorded in the magnetic recording units 116A and 116B while rewinding at a low speed until the hole 111 indicating the tip position of E is detected. The read reader section information is used by the control section 4
The data is stored in the data memory 43 via 7. The reason for reading the reader unit information while rewinding is that flatness is more likely to be achieved and stable information reading is possible than when reading the reader unit information while unwinding the film.

When the reading of the reader section information is completed (YES in # 159), the drive of the feeding motor M is stopped (# 161) and the magnetic heads 18A and 18B are reset to the retracted position (# 163). ), Return.

If the loading detector 35 does not detect the loading of the film 11 within the predetermined time t1 (NO in # 165), it is determined that the loading is defective, and the initialization failure processing is performed according to the flowchart of "Initial NG". (# 167).

FIG. 20 is a flow chart of "Initial NG". When the flow of “Initial NG” is entered, the film 11 is rewound into the film cartridge 9 at a low speed, and the display area 7 of the display unit 7 is displayed during this rewinding period.
A warning display indicating that the loading has failed is displayed at 03 (# 171 to # 177). The warning display is, for example, the display area 703 of the display unit 7 of the film image reproducing apparatus 1.
The film mark FM (see FIG. 28A) is flashed.

Then, the operator issues an instruction to eject the film cartridge 9 or an instruction to reproduce the film cartridge 9 (eject switch 803 or reproduction switch 81).
It is determined whether or not 6 is turned on (# 179, #
185), when a reproduction instruction is issued (YE in # 185)
S), a film image reproduction process described later is performed (#
187).

On the other hand, if the instruction to eject the film cartridge 9 is issued (YES in # 179), it is determined whether or not the reader section information is further read (# 18).
1). If the reader unit information has been read, as in the case of a loading failure after the reader unit information is read while being rewound (Y in # 181).
ES), after the reader unit information stored in the data memory 43 is erased (# 183), the process returns to # 17 (see FIG. 13) and if the reader unit information is not read (# 18).
If NO in 1), the process returns to # 17 without erasing the reader section information in the data memory 43.

Note that the leader section information stored in the data memory 43 is erased in # 183 because the leader section information is not used and the process returns to # 17 and the film cartridge 9 is loaded again and the leader section information is deleted. This is because it is considered that the department information is likely to be read.

Returning to FIG. 14, when the reader section information reading process is completed, the film 11 is loaded again (# 49 to # 61), the base density is taken in during the loading process, and the base density is read. , A correction value in the signal processing of the captured image is calculated based on the read dark output data (# 11) and the reader unit information (# 39) (# 57), and the iris 22 is set to a predetermined value. The aperture value (initial setting value) is set (# 59).

The correction in the signal processing of the picked-up image is as follows.
For example, there are level correction for shading variation of the light source, shading correction, sensitivity variation between pixels, and film-based color correction (correction for removing the base density from the density of a captured image). The level correction, the shading correction, and the sensitivity variation correction are performed in the signal processing in the analog processing unit 24, the correction values of the respective corrections are calculated by the AE / AWB calculation circuit 39, and the calculation results are set in the analog processing unit 24. To be done.

Further, the film-based color correction is performed by A / D
AE / AW performed in the signal conversion process of the converter
Based on the above base density, the B arithmetic circuit 39 performs A / D
The dynamic range of the converter 25 is calculated, and the calculation result is set by the A / D converter 25.

If the film 11 is not loaded within the predetermined time t1 (YES in # 63), it is determined that the loading is defective like the reader information reading process, and the above-mentioned "initial NG" process is performed. Be told (# 6
5).

When the film 11 is normally loaded (YES in # 61), the process proceeds to # 67 (see FIG. 15), and the film 11 is wound up to the final frame F at a high speed (of the feeding motor M). High-speed forward drive), the frame information and the optical information 118 recorded in the magnetic recording units 117A and 117B of the film 11 are read (# 67 to # 7).
3). Then, the unexposed frame F is extracted from the read frame information, and the information of this unexposed frame is stored in the data memory 43 as the reproduction unnecessary frame information (# 75).

Subsequently, the base density is read in the film end portion 11C, and the light quantity of the light source is checked by comparing the base density with a predetermined reference base density (# 81 to # 83). This light amount check of the light source is performed a plurality of times within a predetermined time t2 set in advance (#
77- # 83 loop), in any check, the difference between the base density and the reference base density (density difference) (=
| Detection base concentration-reference base concentration |) is within a predetermined range ε
If it is larger than that (YES in # 83), it is determined that the light amount of the light source is abnormal and a light source abnormality warning is issued (# 85).

The light source abnormality warning is given by displaying an error code in the display areas 707 and 705 of the display unit 7 of the film image reproducing apparatus 1, for example. In addition, a message indicating a light source abnormality is displayed on the monitor TV 2, and the speaker 4
Is performed by generating a voice message of light source abnormality.

Here, the end processing will be described. When shifting to the flow chart of "end sequence", a message of "power OFF" is output (# 321). This message is displayed, for example, by rewinding the film on the display screen 3 of the monitor TV 2, uttering a sound such as "turn off the power" from the speaker 4, or blinking the power lamp 802 of the film image reproducing apparatus 1. Done.

Then, the light source is turned off (# 32
3) The film 11 is fed at high speed to the last frame F among the frames F for which frame information needs to be rewritten (# 325). During this film feeding period, the display during film winding or film rewinding is performed. This display is displayed in the display area 7 of the film image reproducing apparatus 1.
03 or monitor TV2, for example, FIG.
This is performed by displaying the rewind mark FR or the fast-forward mark FF shown in (c).

Subsequently, the film 11 is rewound at a high speed, a frame F for which frame information needs to be rewritten is detected during the rewinding, and the magnetic recording section 117A corresponding to the frame F is detected.
Only the frame information of 117B is rewritten (# 32
7- # 333). When the rewriting of frame information is completed (#
If the leader section information is recorded in the magnetic recording sections 116A and 116B of the film leader section 11A (# 335) and the film 11 is completely stored in the film cartridge 9, the rewinding process is stopped. ((
337).

Subsequently, the light-shielding lid 98 of the film cartridge 9 is closed (# 339), the alignment mark 93 is set at a predetermined position (the "EXPOSED" position) (# 341), and then the eject switch 803 is instructed. It is determined whether or not it is the end processing by (# 343). The alignment mark 93 is set at the position of "EXPOSED" so that it is determined that the film is not a developed film when the film cartridge 9 is taken out and then reloaded, and the reproduction cannot be performed.

The set of the alignment marks 93 is as follows.
As shown in JP-A-5-313234, when the film 11 is rewound, the code of the bar code 94 is detected by the photo reflector 14, and after the film 11 is stored in the film cartridge 9, the use state of the film 11 is detected. This is done by stopping the rotational drive of the spool 91 at the time when the signal pattern of the code corresponding to is detected.

If it is not the instruction of the eject switch 803 (NO in # 343), the power switch 802
Is turned off to end the process (# 345). On the other hand, if it is instructed by the eject switch 803 (#
(YES in 343), the film cartridge 9 is ejected from the film loading section 12 (# 347). Even during this discharging process, the display indicating that the film is being discharged is displayed on the film image reproducing apparatus 1 and the monitor TV2.

Subsequently, the APO timer 44 is reset and then started (# 349). If a new film cartridge 9 is loaded before the APO timer 44 counts up (YES in # 353), AP
After the count operation of the O timer 44 is stopped and the count value is reset (# 355), the process proceeds to # 23 (see FIG. 13), and the film cartridge 9 is initialized. On the other hand, if the APO timer 44 counts up without a new film cartridge 9 being loaded (YES in # 351).
S) After closing the feeding port 99 (# 352), the process proceeds to # 345, the power switch 802 is turned off, and the process is terminated.

Returning to FIG. 15, if the density difference (= | detected base density−reference base density |) is within the predetermined range ε (# 8
3) The light emission amount of the light source is judged to be normal, and the base concentration taken in for checking the light source (see # 77) and the base concentration taken in during loading (see # 55)
Is determined (# 87), and if there is a difference in the base density (YES in # 87), the correction in the signal processing of the image signal is performed based on the base density taken in for checking the light source. The value is calculated again (# 89). The processing content of this correction value calculation is the same as the processing content in # 57. If there is no difference in the base densities (NO in # 87), the correction value calculation process is not performed.

Then, it is judged whether or not the information on the base density and the exposure is recorded in the data memory 43 (# 91 in FIG. 16). If the base density and the like have not been recorded (NO in # 91), the film images of each frame F are sequentially processed from the last frame F to the first frame F by the processing of # 93 to # 111 by the multi-image capturing method. The captured image is captured (reduced as a reduced image) (# 99), the captured image is sequentially reproduced on the monitor TV2 (# 105), and an exposure value (shutter speed) for capturing an image during actual reproduction from the captured image. Tv) and WB adjustment value (amplifier gain G for R and B colors)
R, GB) are calculated (# 101), and the calculation results are sequentially recorded in the magnetic recording units 117A and 117B of the film 11 (# 111).

When the recording of the exposure value and the WB adjustment value for the film image of the first frame F is completed (# 11
1 for YES), the magnetic recording unit 1 of the film reader unit 11A
Information such as the base density is recorded on 16A and 116B (# 113), and the feed motor M is driven in the reverse direction (film 11).
Rewinding) is stopped (# 115), and the initialization process ends.

The exposure value and the WB adjustment value are calculated by the following equation 1, and the calculation results Tv0, GR0, G
B0 is recorded on film 11.

[0155]

## EQU1 ## Exposure value (exposure time) Tv0 = A / G0 WB gain of R color GR0 = G0 / R0 WB gain of B color GB0 = G0 / B0 where A: constant G0: base density of G color Average value B0: average value of base densities of B color.

The picked-up image of each frame F is added to the currently reproduced multi-image for each pick-up, and is reproduced.

FIG. 29 shows a display example of the multi-image displayed on the monitor TV2. This figure shows a multi-display of 24 frames of film images G1 to G24 in an array pattern of 4 rows and 6 columns, and is a display example of the multi images when 9 frames of film images G24 to G16 are read. is there. Since the film image is read in the direction from the last frame F to the first frame F, each film image G24 to G
16 are (1, 1), (1, 2), ..., (2, respectively.
It is arranged at the position of 3).

The tenth and subsequent films G15, G14,
, Are sequentially arranged at the positions (2, 4), (2, 5), ... Of the multi-image shown in FIG. 29 and displayed on the monitor TV2. When the film image of the leading frame F is picked up, 24 film images G24 to
A multi-image in which G1 is arranged in an arrangement pattern of 4 rows and 6 columns is displayed on the monitor TV2.

Returning to FIG. 16, if the base density and the like have been recorded (YES in # 91), the film images of each frame F are sequentially processed from the last frame F to the first frame F by the processing of # 117 to # 131. The images are picked up by the image pickup method for multi-images (captured as reduced images) (# 123), and the picked-up images are sequentially reproduced on the monitor TV2 (# 119). Note that # 11
In the processes of 7 to # 131, since the exposure value and the WB adjustment value for the image during main reproduction are already recorded, these calculations are not performed.

When the display of the film image of the first frame F is completed (YES in # 131), the reverse rotation drive (rewinding of the film 11) of the feeding motor M is stopped (# 11).
5), the initialization process ends.

By the way, in the above embodiment, after the loading of the film 11 is completed, the film 11 is fed to the film end portion 11C to read the film information,
While rewinding the film 11, the film image of each frame F is picked up to display a multi-image (# 99,
# 105, # 123, and # 127), the film image of each frame F may be captured at the same time when the film information is read, and the captured images may be multi-displayed.

17 and 18 are flow charts for displaying the film images of each frame F in a multi-display mode when reading the film information.

FIG. 17 is a block diagram of # 67 and # 6 in FIG.
Image processing for multiple images (# 68) was added between 9 and
An image display process (# 70) for adding a film image captured between 69 and # 71 to a multi-image and displaying the combined image is added. On the other hand, FIG.
And the processing of displaying images of # 127 are deleted, and
Processing of stopping image display immediately after 113 and immediately after 131 (# 1
12, # 132). The deletion of the image display processing and the addition of the image display stop processing in FIG.
This is based on the addition of image display processing to # 70.

According to the flowcharts of FIGS. 17 and 18, after the loading of the film 11 is completed, the film 11 is continuously wound up, the film information corresponding to each frame F is read, and the film image of each frame F is read. Images are picked up by the image pickup method for multi-images, the picked-up images are combined with the multi-images, and sequentially displayed on the monitor TV 2 (# 68 to # 71).

The multi-image in this case is also displayed by the same method as that of the multi-image shown in FIG. 29, but the filming order of each frame F is reversed from that in the case of the flowchart of FIG. The arrangement order of G24 is opposite to that of FIG.

When the film 11 is wound up to the film end portion 11C and the image pickup of the final frame F is completed (# 71
YES), 24 film images G on the monitor TV2
1 to G24 are (1,1), (1,2), ...
The multi-images arranged at the positions (4,5) and (4, 6) are displayed on the monitor TV2. This multi-image display is performed by rewinding the film 11 while exposing the exposure value and W of each frame F.
It is continued while the B correction value is being calculated, and when the calculation process is completed (YES in # 111 or # 131),
It is stopped (# 112 or # 132).

In this embodiment, since the multi-images are sequentially displayed on the display screen 3 of the monitor TV2 when the film 11 is wound, nothing is displayed on the monitor TV2 for a while after the initialization process is started, or the display contents are displayed. The discomfort of the user due to the fact that the value does not change is reduced. Further, since the film images of the frames F of the multi-image are arranged in the order of photographing, there is no sense of discomfort with respect to the displayed multi-image.

In the flowchart of FIG. 17, the multi-image generated every time the film image of each frame F is picked up is sequentially displayed on the monitor TV 2. However, each multi-image is displayed in the period during which the multi-image is displayed. (Film 11 winding and rewinding periods) may be displayed on average. In this way, the rewinding period of the film 11 (# 9
3 to # 111 or # 117 to # 131) monitor TV
Since the content of the multi-image displayed on 2 changes, the discomfort of the user due to the unchanged display content on the monitor TV 2 is further reduced.

Next, the film image reproduction process will be described. Here, as an example, a case where the number of reproduction frames of the film 11 is 24 will be described.

21 and 22 are main flowcharts showing the reproduction processing of the film image.

First, the base density of the film 11 is taken in (# 201). This base density is captured by capturing an image of an unexposed area between the pieces or the upper and lower unexposed areas of the piece. Next, the exposure value and the WB adjustment value (FIG. 16) calculated during the above-described base density and initialization processing.
The exposure value and the WB correction value for each frame F are calculated from the above (see # 101 and # 109) (# 203).

The base densities of the R, G, and B colors captured in # 201 are r1, g1, and b1, and the base densities of the R, G, B colors captured during the initialization process (see # 55 in FIG. 14). ) Is r0, g0, b0, the exposure value Tv1 and the WB correction value (WB gain GR for R1, WB gain GB for B) are calculated by the following formula 2.

[0173]

## EQU00002 ## Tv1 = Tv0. (G0 / g1) GR1 = GR0. (G0 / g1). (R0 / r1) GB1 = GB0. (G0 / g1). (B0 / b1).

It should be noted that the exposure value Tv0,
When the WB correction values GR0 and GB0 are calculated and recorded on the film 11 in the magnetic recording units 116A, 116B, 117A and 117B, the exposure value Tv0 and the WB correction values GR0 and GB0 read from the film 11 are calculated. From the base densities r1, g1 and b1 described above, a suitable exposure value Tv1, WB correction value GR1, at the time of capturing an image for reproduction is obtained by the above-mentioned equation 2.
GB1 is calculated.

Then, the type of the film 11 is discriminated (# 205). As for the camera, as a method of taking a picture, a film is wound one frame at a time when a picture is taken, and the pictures are taken sequentially from the first frame of the film in the backward direction (hereinafter referred to as the normal wind method). Once loaded, the film is temporarily wound up 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. There are two types of methods).

A film which has been taken by the normal wind method (hereinafter referred to as a normal wind film) is shown in FIG.
As shown in 0, the oldest film image G1 is recorded on the leading frame F of the film 11, and the newest film image G24 is recorded on the final frame F. Further, in the pre-wind type photographed film (hereinafter referred to as the pre-wind film), as shown in FIG. 31, the newest film image G24 is recorded on the leading frame F of the film 11, and the oldest film image G1 is recorded on the final frame F. Is recorded.

The type of the film is discriminated by the magnetic information read from the film 11 by the control section 47. For example, the magnetic recording unit 116 of the film reader unit 11A
When the information about the type of film is directly recorded on A and 116B, it is determined from the magnetic information, and when the information about the type of film is not directly recorded,
It is indirectly determined from the photographing date recorded in the magnetic recording units 117A and 117B corresponding to each frame F.

If the film 11 is a normal wind film, the first frame F to be reproduced (frame F not exposed)
Film 11 is wound up to the image pickup start position of the film image (detection position of the hole 111 indicating the leading end position of the frame F) (loop of # 207 to # 211), and shooting conditions for the film image are set (# 213).

The above photographing conditions include, for example, the exposure level and W
B adjustment value, γ correction value, vertical / horizontal conversion condition, trimming condition,
Although there are resolution information, the magnification of the optical system, etc., an unset condition is set here.

Subsequently, based on the set photographing conditions, the light emission amount of the light source 191, the aperture value of the iris 22, the exposure time of the CCD 23 (shutter speed Tv), the WB gain in the analog processing unit 24, and the like of each device and the processing unit. The operating condition is set (# 215).

Then, the low speed feeding of the film 11 is started, and the film image for reproduction is started (# 21).
7). When the film image is reproduced in the high-definition aspect ratio, the reading scan is started at the timing when the leading edge position of the image is fed to the imaging position of the CCD 23,
The reading scan is completed at the timing when the trailing edge of the image passes the image pickup position of the CCD 23.

Therefore, a time lag is provided between the feeding start timing of the film 11 and the reading scanning start timing of the film image in order to adjust the stability of the feeding speed and other conditions, and during this time lag. "REA" is displayed on the monitor TV2 to indicate that it is preparing to start scanning.
The characters “DY” are displayed (# 219, # 221).

The reading scan start timing is the detection of a predetermined elapsed time from the feeding start timing of the film 11 and the hole 111 indicating the leading end position of the film image.
Is detected, a predetermined feed amount of the film 11 is detected, and the like. Further, the reading scan may be started at the timing when the feeding speed of the film 11 reaches a predetermined low speed.

Further, during the preparation for starting the reading scan, it is judged from the format information whether or not the reproduced image has the standard size (# 223), and if it is the standard size (# 223).
YES), a process of delaying the start timing of the reading scan by a preset predetermined time Td is performed (#
225).

When the reproduction image has a standard size, the delay process of the read scan start timing is performed when the reproduction image GL is generated in an area where both ends of the film image are removed by d1 as shown in FIG. 9B. It is based on being. Therefore, assuming that the feeding speed of the film 11 is v, when the reproduced image has a standard size, the read scan start timing is d1 / v from the normal read scan start timing.
Only delayed.

Subsequently, the film image capturing process is performed according to the flowchart of the subroutine "main scan" shown in FIG.

When the subroutine "main scan" is called, first, the number of read lines M is set (# 28
1) Then, the counter K that counts the number of lines actually read is reset to "0"(# 283). The read line number M is a predetermined line number according to the size of the reproduced image of the frame F. When the reproduction size is the standard size, a predetermined intermediate range excluding both ends of the film image is scanned (see FIG. 9B), and thus the number of lines M1 corresponding to the predetermined range is set as the number of read lines. , If the playback size is not the standard size, the entire range is scanned in the scanning direction of the film image (see FIG. 9).
(See (a) and (c)), the number of lines M2 corresponding to the entire range
Is set as the number of reading lines.

Subsequently, the feeding motor M is driven at a predetermined speed to feed the film 11, and the film image of the frame F is read (loop of # 283 to # 303). The film image is captured line by line every time the film 11 is fed by one line (# 295), and the line image is captured until the rear end position of the image capturing range is detected (# 301 or # 3).
It is repeated until it becomes YES in 03).

In the main scan, abnormal feeding of the film 11 is checked so that the film image can be taken normally. That is, feeding motor M
Is driven by a predetermined amount corresponding to one line ((#
285), it is determined whether or not the film 11 is normally fed by one line by this driving (# 287).

The above determination is made by, for example, monitoring the drive current value and load torque of the feeding motor M or checking the feeding failure (cutting, catching, slipping, etc.) of the film 11, and the feeding of the film 11 is normal. (# 2
If YES at 87, one line of image is picked up (# 29
5) If the film 11 is not normally fed (NO in # 287), the driving of the feeding motor M is immediately stopped (# 289), and the film is displayed on the display unit 7 of the film image reproducing apparatus 1. After an error display indicating a feeding abnormality is displayed (# 291), the power OFF process is performed (# 29).
3). The power-off processing is to stop the processing, turn off the power switch 801 and enter a standby state until the error content is cleared.

Subsequently, when the reproduced image is not in the standard size and the film 11 is fed to the rear end position of the film image capturing range (YES in # 301), the image capturing operation is stopped (# 305). The suitability of the exposure and the imaging range of the captured image is determined (# 307, # 309). If the exposure or the imaging range of the captured image is not proper (NO in # 307 or # 309), an error display indicating that the film image has been read is displayed on the display unit 7 of the film image reproducing apparatus 1 (#). 311) again, the process proceeds to # 213 to read the film image of the frame F again, and if the exposure or the imaging range of the captured image is appropriate (# 307 and # 3).
(YES at 09), and returns.

When the reproduced image has the standard size, when the reading of the film image is completed by the predetermined number of lines M1 (YES in # 303), the image pickup operation is stopped (# 31).
3), it is determined whether or not the captured image is appropriate for exposure (# 315). Then, if the exposure of the captured image is not proper (NO in # 315), an error display indicating that the film image has been read abnormally is displayed on the display unit 7 of the film image reproducing apparatus 1 (# 311), and then, again. The process moves to # 213 to read the film image of the frame F, and if the exposure of the captured image is appropriate (YES in # 315), the process returns.

Returning to FIG. 21, when the film image capturing process is completed, the captured film image is reproduced and displayed on the monitor TV 2 based on the set predetermined rendering method (# 2).
29). Subsequently, it is determined whether or not a change in the display method of the reproduced image is instructed (# 231), and if a change in the display method is instructed (YES in # 231), the display method is changed based on the changed content. Then, the reproduced image is displayed again (# 233). On the other hand, if the display method change is not instructed (NO in # 231), the current reproduction display is continued.

Subsequently, it is judged whether or not the reproduced frame F is the film image G24 of the final frame (# 235), and if it is not the final frame (NO in # 235), the flow returns to # 207 to return to the next frame F. The reproduction process of the film image is performed. After that, the reproduction process is sequentially performed from the film image G1 of the first frame F, and when the reproduction process of the film image G24 of the last frame F ends (YES in # 235), the film 11 is rewound by a predetermined number of frames. After that (# 237), the reproduction process ends.

In the rewinding process of the film 11 of # 237, the film 11 is preliminarily fed to a predetermined position in order to quickly search the reproduction frame F when the next reproduction process is instructed. It is something to put. The predetermined position is, for example, a reading position of the first piece, the last piece, the center piece, or the like. When it is often reproduced from the film image G1 of the leading frame F, the above-mentioned predetermined position may be set as the leading frame.
Assuming that the first piece F to be reproduced is random, it is advisable to set the center piece position where the average value of the access time to the first piece F is the minimum as the predetermined position.

If the film 11 is a prewind film in # 205, the process proceeds to # 241 (see FIG. 22).
241 to # 275 are executed to reproduce the film image of each frame F in the same manner as the normal wind film.

In the prewind film, since each frame F is photographed in the direction from the rear end portion to the front end portion of the film 11, the final frame F at the rear end portion of the film 11 (first frame F to be reproduced). Will be fed at high speed to the reading position (# 24
1). Then, the film images G1, G2, ..., G24 of each frame F are sequentially reproduced while feeding the film 11 to the front end side (# 241 to # 275), and the first frame F (the last film image G24 is photographed. When the reproduction process of the frame F) is completed (YES in # 267), the film 11 is rewound by a predetermined number of frames (# 275), and then the reproduction process is completed.

In the main scan of each frame F, when the positioning of the reading position of the film image is completed, the frame F concerned is read.
It is determined whether or not the film image is a non-exposed frame and is a frame to be reproduced. However, in the case of a prewind film, the final frame F (first film image G1
It is considered that there is little unexposure of the frame of which the image has been photographed). Therefore, it is determined whether the second frame F (the frame of which the film image G2 is photographed) is an unexposed frame or not. I have to.

That is, in the reproduction processing of the normal wind film of FIG. 21, the leading frame F (film image G
In order that the unexposed frame can be discriminated after the positioning of the reading position of the frame (1 is photographed) is completed, the unexposed frame discrimination process (# 2) is performed after the imaging frame positioning process (# 209).
11) is included, but in the prewind film reproduction process of FIG. 22, the process of positioning the last frame F (#
After 243), the unexposed frame determination process is not inserted, but the unexposed frame determination process (# 273) is inserted after the next frame positioning process (# 271).

32A and 32B are views showing the film feeding control in the reproducing process. FIG. 32A shows the feeding control for the normal wind film, and FIG. 32B shows the feeding control for the prewind film. It is a figure.

In the figure, a thin arrow Q1 indicates the scanning direction of the film image in the main scan, a thick arrow Q0 indicates the feeding of the film 11 from the first frame to the last frame, and an arrow Q2 indicates a frame. Between the frame and the frame 11
Shows the delivery of. The circled numbers attached to the arrows Q1 and Q2 indicate the order of main scanning (the reading order of film images). Since the film 11 is fed by searching the reading position of each frame F as indicated by arrows Q0 and Q2, it is fed at a higher speed than the main scan indicated by arrow Q1.

In the case of a normal wind film, the film images G1, G2, ... G24 are sequentially picked up and reproduced and displayed on the monitor TV2 while the film 11 is being rewound from the state where the film 11 is rewound.
As shown in (a), the film 11 is simply fed in the winding direction.

On the other hand, in the case of the prewind film, since the film images G1, G2, ... Are arrayed in the direction from the film end portion 11C to the film leader portion 11A, when the reproduction process is started, the film 11 is first. Is wound up to the reading position of the film image G1 at a high speed, and thereafter, the film 11 is read by performing a main scan in the winding direction, and the film image G1 is reproduced and displayed. When the playback display of the film image G1 is completed,
After rewinding the film 11 to the reading position of the film image G2 at a high speed, the feeding direction of the film 11 is reversed, and the film 11 is mainly scanned in the winding direction to perform the film image G.
1 is read, and the film image G1 is reproduced and displayed.

Hereinafter, the film images G2 and G2 are repeated by repeating high-speed feeding in the rewinding direction for positioning the reading position of the film image and low-speed feeding in the winding direction for the main scan.
3, ... G24 is imaged and reproduced and displayed. That is, in the case of a prewind film, the film 11 is fed in the rewinding direction while reciprocating.

The reproduction process is for reproducing the photographed frames F in order according to a predetermined reproduction order. The operator searches the photographed contents of the film 11 to selectively select a desired frame F. There are times when you want to display the playback.

Next, the reproduction control for selectively reproducing and displaying the desired frame F will be described with reference to the "frame selection" flowcharts shown in FIGS.

The reproduction process for selectively reproducing and displaying the desired frame F (hereinafter referred to as the search reproduction process) is performed in a predetermined search mode. For example, when the search mode is set by the mode switch 806, "Frame selection"
The reproduction process is performed according to the flowchart in FIG.

In the "frame selection" flowchart, it is checked whether the fast-forward switch 816 or the rewind switch 813 is ON (pressed) (# 361, # 363). In the search / playback process, the fast-forward switch 816 and the rewind switch 813 are switches for instructing the search direction of the frame F photographed on the film 11.

When the fast-forward switch 816 is turned on (YES in # 361), the film 11 is wound up to position the reading position of the next frame F (# 363), and the main scan is further performed. An image is captured (# 36
7), the captured image is reproduced and displayed on the monitor TV 2 (#
369). Since the first reproduction frame indicates the search start frame, a normal reproduction image is displayed on the monitor TV 2 as shown in FIG. In the figure, A is a frame number, and B is information such as shooting date and time and title.

Subsequently, it is judged whether or not the fast-forward switch 816 is kept ON (# 371), and if the fast-forward switch 816 is OFF (N in # 371, N is returned).
O), and shifts to # 363. Fast-forward switch 816 O
If the N state continues (YES in # 371), the film 11 is wound up at a semi-high speed (roughly scanned at the semi-high speed), the film image of the next frame F is captured, and the captured image is It is reproduced and displayed on the monitor TV 2 (# 373 to # 3).
77). Then, while the fast-forward switch 816 continues to be in the ON state, film images of the next frame F are sequentially captured in frame order, and the captured images are reproduced and displayed on the monitor TV2 (loop of # 375 to # 379). .

The rough scan is for picking up a film image for multiple images. Therefore, the term "semi-high speed" means that the speed is higher than the speed of the film 11 in the main scan, but lower than the normal winding / rewinding speed.

Since the images picked up for multi-image use are thinned out as compared with the normal reproduced images as described above (see FIG. 11), the display screen 3 of the monitor TV 2 is shown in FIG. As shown, the image C having a size smaller than the regular reproduced image is reproduced. In the figure, A is a frame number.

The second and subsequent reproduction displays are performed with images picked up for multiple images because the reproduction image is a search image and does not require a high image quality like a normal reproduction image. . Also, the reason why the captured image is not enlarged to the size of the reproduced image and displayed is that the film image is captured at a low resolution by the interlace scanning, so if the captured image is magnified and played back, the quality of the reproduced image deteriorates extremely. Then
This is because the operator will feel uncomfortable or uncomfortable.

When the fast-forward switch 816 is released from the ON state during the search and reproduction process (YES in # 379), the feeding of the film 11 is stopped (# 381), and the frame F at the stop position is stopped.
The frame F to display the film image of
After positioning the reading position of the film image of ((#
383), and returns to # 367. The reason why the film image of the frame F at the stop position is displayed as a normal reproduced image is that this frame F indicates the search end frame.

[0215] The "frame selection" flowchart is entered, and the rewind switch 813 is turned on (pressed).
Alternatively, the rewind switch 813 is turned on during the search / playback process.
When it becomes N (YES in # 363), if the frame information needs to be rewritten, the frame information of the frame F is simultaneously rewritten during the rough scan (# 385, # 38).
7, # 401, # 403) is added, and the search / playback process is performed in the same procedure as when the fast-forward switch 816 is pressed (# 385- # 41).
1). That is, each step of # 391 to # 399 is
Corresponding to each step of # 367 to # 375, # 405 to # 405
Each step of # 411 corresponds to each step of # 377 to # 383.

Therefore, when the rewind switch 813 is turned on, it is determined whether or not the frame information needs to be rewritten for the search start frame F (# 385), and the frame information needs to be rewritten. If (YES in # 385), the frame information is rewritten while the film 11 is rewound to the reading position of the film image of the search start frame F (# 387). Then, the film image of the search start frame F is captured as a normal reproduced image by the main scan,
The captured image is reproduced and displayed on the monitor TV 2 (# 39).
1, # 393).

Regarding the second and subsequent retrieval pieces F,
When the rough scan of the film image of each frame F is started (# 399), it is determined whether the frame information of the frame F needs to be rewritten (# 401), and the frame information needs to be rewritten. If so (YE in # 401
S), the frame information is rewritten at the same time as the rough scan is performed (# 403). And each piece F
The film image of No. 2 is reproduced and displayed on the monitor TV 2 as an image picked up for multiple images by rough scanning (# 399 to # 405).

In the rewinding direction search of the reproduction frame F, unlike the winding direction search, the film image of each frame F is scanned from the rear end side to the front end side to be imaged. This is because if the film image of each frame F is scanned from the front end side to the rear end side similarly to the case of searching in the winding direction, each frame F is scanned.
Rewinding of the film 11 for positioning the reading position of the film image and winding up of the film 11 for picking up the film image of each frame F are alternately performed, and the rewinding direction search and reproduction process is performed. This is because it becomes significantly slower than the search and reproduction processing in the direction.

In the rewinding direction search / reproduction processing, the scanning directions for writing frame information on the film 11 coincide with each other, and in the rough scan of the film image of each frame F, the film 11 writes the magnetic information. Since the paper is fed at a speed substantially the same as the feeding speed at the time of loading, the frame information rewriting processing required during the rough scan is performed to improve the efficiency and speed of the processing.

By the way, in the winding control of the film 11, the film 1 is controlled by the inertia of the drive motor M and the feeding mechanism.
1 is rolled up more than necessary from the end position and film 1
1 may be damaged. Therefore, in the winding control of the film 11, the driving of the drive motor M is stopped before the film 11 is completely pulled out from the film cartridge 9, and the film 11 is completely pulled out from the film cartridge 9 and cannot be further wound up. Need to do so.

In this embodiment, the hole 115 indicating the rear end position of the film end portion 11C is detected, and the drive motor M is stopped based on this detection.

The stop control of the drive motor M is performed according to the flow chart of "end detection" in FIG.

The flowchart of "End detection" in FIG. 27 shows a hole 114 indicating the leading end position of the film end portion 11C.
Since the distance between the hole 115 indicating the rear end position and the hole 115 indicating the rear end position is shorter than the distance between the hole 111 indicating the front end position and the hole 112 indicating the rear end position provided corresponding to each piece F, the front end of each piece F The film 11 while detecting the feeding time T between the position and the rear end position
And the feeding time T detected last time
If it becomes shorter than this, it is judged that the feeding time T is the time for feeding between the leading end position and the trailing end position of the film end portion 11C, and the hole 115 indicating the trailing end position of the film end portion 11C is detected. I am trying.

That is, it is judged whether or not the feeding speed of the film 11 is low (# 421), and if the feeding speed is low (YES in # 421), the process proceeds to # 423 and #
423 to # 439, the end detection processing of the film 11 according to the low speed feeding is performed, and if the feeding speed is high (# 42
If NO in 1), the process proceeds to # 439, and in # 439 to # 455, the end detection process of the film 11 according to the high speed feeding is performed.

The end detection processing for low speed feeding and the end detection processing for high speed feeding are the reference feeding times Tr1 and Tr set in the first time memories T _n-1 and T _m-1.
2 is different, each step of # 423 to # 439 corresponds to each step of # 439 to # 455, and the basic processing procedure is the same. Therefore, in the following detailed description, end detection for low speed feeding will be performed. Only for processing.

The reference feeding times Tr1 and Tr2 are
Is set as the feeding time T0 because there is no feeding time T0 for the previous piece F to be compared with the feeding time T1 measured for the first piece F.

When the feeding speed of the film 11 is low, the preset reference feeding time Tr1 is set in the first time memory T _n-1 of the memory 362 (# 423). Next, the hole 11 showing the tip position of the first piece F after the start of winding.
When 1 is detected (YES in # 425), timer T3
When the counting of (corresponding to the timer 361 in FIG. 4) is started (# 427) and the hole 112 indicating the rear end position of the first piece F is detected (YES in # 429), the counting of the timer T3 is stopped. (# 431), this count time (feeding time) T1 is stored in the second time memory T _n of the memory 362 (# 433).

Subsequently, the count time T1 stored in the _first time memory T _n-1 is compared with the reference feeding time Tr1 stored in the second time memory T _n , and the count time T1 is calculated. It is judged whether or not it is much smaller than the reference feeding time Tr1 (# 435), and the counting time T
If 1 is much smaller than the reference feeding time Tr1 ((#
(YES in 435), it is determined that the hole detected in # 427 is the hole 115 indicating the rear end position of the film end portion 11C, and the driving of the drive motor M is stopped (# 439).

The count time T1 is the reference feeding time Tr.
If substantially the same as 1 (NO in # 435), the contents of the first time memory T _n-1 are rewritten to the count time T1 (# 437), and then the process returns to # 425 and # 425.
From # 433, the feeding time T2 for the second frame F is counted, and the contents of the second time memory T _n are rewritten by the count result.

Next, the feeding time T2 for the current frame F stored in the _first time memory T _n-1 and the second time T2 are stored.
Is compared with the feeding time T1 for the previous frame F stored in the time memory T _n , and the feeding time T2 is the feeding time T1.
Is very small compared to (# 43
5).

If the feeding time T2 is much shorter than the feeding time T1 (YES in # 435), it is determined that the hole detected in # 427 is the hole 115 indicating the rear end position of the film end portion 11C. Then, when the driving of the drive motor M is stopped (# 439) and the feeding time T2 is substantially the same as the feeding time T1 (NO in # 435), the contents of the _first time memory T _n-1 Is rewritten to the count time T2 (# 437), and the process returns to # 425.

Every time the feeding time T _n of each piece F is detected, the feeding time T _n for the present piece F is compared with the feeding time T _n−1 for the last piece F to compare the present feeding time. If the feeding time T _n is much smaller than the previous feeding time T _n-1 (YES in # 435), it is determined that the hole 115 indicating the rear end position of the film end portion 11C has been detected. Then, the drive of the drive motor M is stopped (# 439).

In this embodiment, the film end portion 1
Although the hole 115 indicating the rear end position of 1C is detected and the drive motor M is stopped based on this detection, for example, a mark indicating the film end portion 11C is attached to the film 11 and this mark is detected. Alternatively, the drive motor M may be stopped. Further, the frame number assigned to each frame F may be detected, and when the frame number F of the maximum frame number is exceeded, it may be judged that the film end portion 11C has been reached and the drive motor M may be stopped. The pull-out amount may be detected, and the drive motor M may be stopped when the film 11 is pulled out by a predetermined amount or more.
