Abstract

PROBLEM TO BE SOLVED: To provide an image processor which can detect with high accuracy both standard and full panoramic frames which are mixed together and recorded on a photographic film. SOLUTION: The image data equivalent to a single piece of photographic film are fetched by a scanner, and the film base density is detected from these image data. The threshold is added to the film base density to decide the reference value and the pixels exceeding this reference value are extracted from the whole area of the photographic film. Then it is decided whether the length of a rectangular frame consisting of a set of extracted pixels is approximately equal to the length of a standard frame or a full panoramic frame. The rectangular frame having its length approximately equal to the length of the standard or full panoramic frame is decided as an image frame having its clear edge and the position data and size of this image frame are registered.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image processing apparatus, and more particularly to an image processing apparatus for easily handling image frames of different lengths recorded in a photographic film.

[0002]

2. Description of the Related Art A camera has been provided which records image frames having different lengths in a film feeding direction on a photographic film. For example, Fujifilm TX-1 (trade name) sold by the applicant has a 35mm standard size (24 × 36mm) and a full panorama size using almost two frames of the standard size for 135 size photo film. (24
X 65 mm).

When printing each image of a photographic film in which image frames having different lengths are mixed, a full panorama frame is found and a paper mask is used for the full panorama frame. It is necessary to perform a switching operation or the like, and the printing process is complicated.

As a method of printing a full panorama frame without switching the paper mask to a large size, a full panorama frame is divided in a film feed direction as disclosed in Japanese Patent Application Laid-Open No. 4-326345. In some cases, the image is divided into fixed image areas, and each time the image areas are exposed, the image area is fed by the length of the image area to obtain a landscape print.

[0005]

As described above, in the conventional method, when printing an image frame long in the film feed direction such as a full panorama frame, switching of a paper mask, division into a certain image area, sequential printing, and the like are performed. And the printing process becomes complicated. Further, in a photographic film in which a standard frame and a full panorama frame are mixed, there is a problem that the print processing cannot be performed efficiently because the size is manually determined.

[0006] The present invention is to solve the above problems,
It is an object of the present invention to provide an image processing apparatus which can easily process each image frame even if the photo film has different size frames recorded in different lengths in the film feed direction.

[0007]

In order to achieve the above object, according to the first aspect of the present invention, each of the densities at a plurality of locations in a measurement area including an image recording range on a photographic film on which an image is recorded is measured. An image processing device that specifies the position and size of the image based on the measured density and performs image processing based on the specified position and size; First specifying means for specifying the recording position and size of an image frame having a clear edge based on one image data, and based on the image frame and size specifying the recording position and size by the first specifying means. And second specifying means for specifying the recording position and size of the image frame whose edge is unclear.

The sizes are at least two types: a standard size and a different size in which the length in the film feed direction is changed with respect to the standard size. It is preferable that both images are displayed so that they have substantially the same length, and the verification process is performed based on the images. Further, it is preferable that the image after the change instruction is displayed by changing the enlargement / reduction ratio according to a size change instruction input which is input while observing a display screen in the test processing. Further, it is preferable to include an index image creating unit that creates an index image based on the specified size. Further, it is preferable to include a cutting position specifying means for specifying a film cutting position between each image frame based on the specified recording position and size.

FIG. 2 is a schematic diagram of a digital print system embodying the present invention. The printing system 10 includes a line CCD scanner 11, an image processing device 12, a laser printer 13, a processor 14, and a film cutting inserter 15. The line CCD scanner 11 and the image processing device 12 are integrated as an input device 16, and the laser printer 13 and the processor 14 are integrated as an output device 17. Film cutting inserter 15
Cuts the 135-type photographic film 18 into, for example, film pieces 18a every six frames. The film piece 18a is put in a film sheath 19 and returned to the customer together with a print photograph.

FIG. 3 shows a schematic configuration of an optical system of the line CCD scanner 11. This optical system includes a light source 21 such as a metal halide lamp or a halogen lamp. The light source 21 is arranged on the reflector 22 at its focal position. The reflector 22 is made of a material that transmits infrared light (IR), and its reflection surface is formed in a parabolic shape. Light from the light source 21 is reflected by the reflector 22.
And is irradiated toward the photographic film 18. Note that an LED or the like may be used as the light source 21.

On the light emitting side of the light source 21, an IR cut filter 24, a light amount adjusting diaphragm plate 25, a balance filter 2
6. The light diffusion box 27 and the diffusion plate 27a are arranged in order along the optical axis L. The insertion position of the light amount adjustment diaphragm plate 25 into the optical axis L is variable, and the light amount is thereby adjusted. The balance filter 26 is provided with a negative film filter 26a and a reversal film filter 26b for color temperature adjustment, and one of them is selectively inserted into the optical axis L.

The photographic film 18 is a film carrier 2
8 conveys the image recording surface so as to be perpendicular to the optical axis L. The film carrier 28 has a carrier base 3
0, a film mask 31, a conveying roller pair 32, etc., for feeding the photographic film 18 in the longitudinal direction indicated by arrow A. The film carrier 28 is 135 type, IX24
These are provided for the 0 type and the other 110, 120, and 220 types, respectively, and by setting those that match the film type in the scanner 11, images of various films can be read.

The film mask 31 is arranged along the width direction of the photographic film 18, and the length of the opening 31a is formed slightly larger than the width of the photographic film 18. The image is captured by the image sensor 36 via the imaging lens unit 35 so as to include the edges at the ends and both side edges.

The imaging lens unit 35 and the image sensor 36 are arranged in order along the optical axis L on the opposite side of the photographic film 18 from the light source 21. The imaging lens unit 35 forms an image recorded on the photographic film 18 on a light receiving surface of the image sensor 36. Although FIG. 3 shows only a single lens as the imaging lens unit 35, the imaging lens unit 35 may be a plurality of zoom lenses or the like.

The image sensor 36 has R, G, and B CCs.
The D cell row is moved in the feed direction of the photo film 18 (arrow A in FIG.
Direction). Each CCD cell row is C
The CD cells are arranged in a line in the width direction of the photo film 18. Thus, the main scanning for reading the film image is performed in the arrangement direction of the CCD cells. Also,
When the photographic film 18 is sent, sub-scanning for reading a film image is performed.

The image sensor 36 has three C
Since the CD cell rows are sequentially arranged at a predetermined pitch along the feed direction of the photo film 18, there is a time difference between the detection timings of the R, G, and B component colors in the same pixel. For this reason, in the present embodiment, the detection timing of the photometric signal is delayed by a different delay time for each component color, whereby the R, G, and B photometric signals of the same pixel are simultaneously output from the line CCD. . After the output signal from the line CCD is amplified by the amplifier circuit 37, it is converted into a digital signal by the A / D converter 38 and sent to the image processing device 12.

The image processing device 12 specifies the recording position and size of the image frame to be printed from the scan data, and sends the recording image data of the image frame to be printed to the laser printer 13. The laser printer 13 includes R, G, and B laser light sources and a modulator. Then, the laser light is modulated according to the image data for recording,
The modulated laser light is applied to the printing paper, and an image is recorded on the printing paper by scanning exposure. In addition, processor 14
Applies color developing, bleach-fixing, washing, and drying processes to photographic paper that has been scanned and exposed. As a result, an image is formed on the printing paper.

Next, the configuration of the image processing apparatus 12 will be described. As shown in FIG. 4, the image processing device 12 includes a data processing unit 40, a logarithmic converter 41, a pre-scan memory 4
2. Fine scan memory 43, prescan processing unit 44, fine scan processing unit 45, and condition setting unit 4
6. In addition, the image processing apparatus 12 includes an input unit and a display unit 51 such as a personal computer.
And a control unit that controls and manages the entire print system including the processing device 14 via the printer.

Each of the RGB digital signals supplied from the scanner 11 to the image processing device 12 is first subjected to predetermined data processing such as darkness correction, defective pixel correction, and shading correction in a data processing section 40. Later, the logarithmic converter 41 performs logarithmic conversion to obtain density data. The density data is stored as image data in the pre-scan memory 42 in the case of pre-scan, and in the fine scan memory 43 in the case of fine scan.

The image data stored in the prescan memory 42 is sent to a condition setting section 46 and a prescan processing section 44.
Is read and processed. The image data stored in the fine scan memory 43 is read out by the fine scan processing unit 45 and processed. The pre-scan processing unit 44 and the fine scan processing unit 45 include an image data processing unit 47, 48 and an image data conversion unit 49, 5, respectively.
Has zero.

In the image data processing units 47 and 48 of the pre-scan processing unit 44 and the fine scan processing unit 45,
According to the processing conditions set by the condition setting unit 46,
In a portion where predetermined image processing is performed on image data read by the scanner 11, basically the same processing is performed except that the resolution is different. The image processing in both processing units is not particularly limited, and various known image processing can be applied.

Image processing includes, for example, gray balance adjustment, gradation correction, density (brightness) adjustment, and matrix (MTX) using an LUT (look-up table).
Illuminant type correction and image saturation adjustment (color adjustment). Also, low-pass filter, adder, LUT, MTX
Electronic zooming, dodging (compression / expansion of density dynamic range), sharpness (sharpening), etc., using averaging, interpolation, or the like performed by using these methods or by appropriately combining them. Can be

The image data converter 49 of the prescan processor 44 converts the image data from the image data processor 47 into
If necessary, thin out and use a 3D LUT, for example,
The image data is converted into image data for display by the display unit 51 and supplied to the display unit 51. Thereby, the test screens 65 and 66 as shown in FIG. The operator refers to the verification screens 65 and 66 and operates various correction keys of the key correction unit 56 as necessary to input a correction value.
Similarly, the image data conversion unit 50 of the fine scan processing unit 45 converts the image data processed by the image data processing unit 48 into image data for the laser printer 13 using a three-dimensional LUT or the like, and 1
Supply 3

The condition setting section 46 has a setup section 55, a key correction section 56, and a parameter integration section 57. The condition setting unit 46 sets various processing conditions in the pre-scan processing unit 44 and the fine scan processing unit 45, reading conditions for pre-scan and fine scan, and reading conditions for scanning. For example, from the film type information recorded on the barcode of the photo film 18, the prescan reading conditions are determined based on the film base density information corresponding to the previously stored film type. Further, from the pre-scanned image data, a density histogram of the photographic film 18 is created, and image feature amounts such as average density, highlight (lowest density), and shadow (highest density) are calculated, and reading conditions for fine scan are calculated. Is determined, and an LUT for performing gray balance adjustment, density adjustment, gradation correction, and the like is created, an MTX operation formula is created, and a sharpness correction coefficient is calculated in accordance with an instruction from an operator performed as necessary. , Various image processing conditions in the pre-scan processing unit 44 and the fine scan processing unit 45 are set. Further, the edge position and the size of each image frame recorded on the photo film 18 are specified based on the prescanned image data.

The key correction unit 56 includes keys for adjusting density (brightness), color, contrast, sharpness, saturation, and the like preset on the keyboard 58, and various instructions input from an input unit such as a mouse. The amount of adjustment of the image processing condition is calculated in accordance with
To supply.

The parameter integration section 57 receives the image processing conditions set by the setup section 55 and sets them in the pre-scan processing section 44 and the fine scan processing section 45. Further, the image processing condition set for each part is corrected or reset according to the adjustment amount calculated by the key correction unit 56.

FIG. 1 is a flowchart showing a process of specifying the edge position and size of an image frame in the setup section 55. The processing for specifying the edge position and the size is performed based on the prescan data. FIG.
FIG. 9 shows an example of pre-scan data. This pre-scan data 59 is 1
An image is taken in a large imaging range around the image, whereby a background image 61 having nothing is included around the photo film image 60.

First, based on the pre-scan data 59,
The front end 60a and the rear end 60b of the photographic film image 60 are detected. The pre-scan data 59 is for the photo film 1
Since the imaging range is set to be one rotation larger than 8, a photographic film image 60 and a background image 61 surrounding the photographic film image 60 are present in the data. The background image 61 is a set of pixels having a lower density than the photo film image 60. For this reason, the leading edge 60a, the trailing edge 60b, and both side edges 60 of the photographic film image 60 are changed due to the density change between the photographic film image 60 and the background image 61 having nothing else.
c and 60d are detected. That is, in the direction orthogonal to each end 60a to 60d of the prescan data, each end 60a to 60d
The change in density from 60d is determined. And the background image 61
, A pixel having a density equal to or higher than a predetermined threshold is found, and the location where this pixel is found is defined as each of the film ends 60a to 60d.

Next, based on the film tip 60a,
The lowest density in the central region in the width direction of the photographic film image 60 (for example, a region having an area of 1/4 of the area of the standard frame image) is extracted, and the lowest density is extracted as the film-based density. Dfb.

Next, pixels having a density equal to or more than a fixed threshold value A1 (for example, A1 = 0.1d (density value)) than the film base density Dfb are extracted over the entire area in the film feeding direction (sub-scanning direction). I do. By extracting the pixels, each image frame appears as a rectangular frame. If this rectangular frame has a value close to the size of the standard image frame (standard frame),
This is determined as the standard frame SF, and the position data of the standard frame SF is registered. If the rectangular frame has a value close to the size of a full panorama image frame (full panorama frame), this is determined as a full panorama frame PF, and the position data of this frame PF is registered.

When the long side of the rectangular frame of the standard frame SF is LSa, the short side is LSb, and the length of the long side of the detected rectangular frame is FLa and the short side is FLb, When the conditional expression is satisfied, the position of each edge is registered as the standard frame SF. LSa-LC1≤FLa≤LSa + LC1 LSb-LC2≤FLb≤LSb + LC2 where LC1 and LC2 are numerical values that give an allowable range in the determination, and are preferably used in the range of 0.5 to 3.0 mm in terms of mm. .

Similarly, when the long side length of the rectangular frame of the full panorama frame PF is LPa and the short side length is LPb, the full panorama frame PF is satisfied when the following conditional expression is satisfied.
Is registered as the position of each edge. LPa-LC3 ≦ FLa ≦ LPa + LC3 LPb−LC4 ≦ FLb ≦ LPb + LC4 Here, LC3 and LC4 are numerical values that give an allowable range for determination, and are preferably used in the range of 0.5 to 3.0 mm in terms of mm. . In determining the size of the standard frame SF and the full panorama frame PF, the short side length is also used as a criterion. However, this may be omitted, and each size determination may be performed based only on the long side length.

In this embodiment, in order to specify each edge position of each frame, the number of pixels in the sub-scanning direction up to each edge position is used with reference to the leading end 60a of the photographic film image 60. May be any data that can specify the position of other distance data or the like. For example, a value obtained by converting the number of pixels into the number of drive pulses of a feed motor for feeding a film may be used.

Next, it is determined whether or not the registered image frames SF and PF are connected with a predetermined gap. That is, it is determined whether or not the registered image frames SF and PF are continuous at the standard gap G1. When there is a discontinuous portion, the threshold A2 is slightly increased from A1 (for example,
Using A2 = 0.3d), pixels are extracted again for the discontinuous portion. By using the threshold value A2 that is slightly larger than the threshold value A1, it is possible to correctly recognize a frame image of a frame shot with overexposure.

For example, when an image is photographed due to overexposure at the time of photographing with a camera, there is a density that can be determined as an image between frames. In this case, the threshold A1
Is used, this density portion is also picked up, and as a result, each frame becomes a continuous large frame image. By increasing the threshold, the density pixels in the gap can be canceled, and a continuous large frame image can be recognized as a plurality of normal frame images.

In this embodiment, the thresholds are A1, A2
Are set in two stages to make it possible to identify the frame image due to the unclear edge caused by the frame shot with the overexposure. However, even if the frame image is identified by one or three or more threshold changes, Good.

FIGS. 7A and 7B show registered image frames extracted by reference values using the threshold values A1 and A2. FIG. 7A shows registered image frames SF1 and PF1 based on the reference value Dfb + A1, and FIG. Registered image frame S based on reference value Dfb + A2
F2 is shown.

In this manner, all the image frames SF, P
When F is detected, the processing for specifying the position of each frame SF, PF is completed. Also, in the extraction of the pixels again after changing the threshold value, as shown in FIG.
If the PF cannot be extracted, as shown in FIG. 8, based on the determined image frames SF1 and SF2,
The position of an unregistered image frame is estimated and registered. The position is estimated by determining the average lengths FLSave,
FLPave and gap average Gave are obtained, and these FLS
Using ave, FLPave, and Gave, the frame is determined on the basis of the determined frame adjacent to the undefined frame, for example, the edges Ef1 and Ef2 of SF1 and SF2.

First, average data such as the average lengths FLSave and FLPave of the determined frames SF and PF and the average gap Gave are obtained. Next, the length Lun between the determined edges Ef1 and Ef2 of each determined frame is obtained. Next, it is determined whether the undetermined length Lun is a standard size frame, a full panorama size frame, or a mixture of these. This determination is made based on whether or not the undetermined length Lun is substantially the same as the standard length when each size frame exists. When the determination result is a standard size frame, the determined edge is specified as follows.

FIG. 8 shows a case where there is an undetermined standard frame SF5 between the determined frames SF1 and SF2. The unconfirmed standard frame SF5 is, for example,
It is divided so as to have two density areas DA1 and DA2, and the edge on the rear end side in the density area DA2 is unclear. In the camera, the photo film 18
Focusing on the fact that there is no change in the size of the screen to be shot, although the feed amount may vary, the recording position of frames with unclear edges is specified based on the size of the shot screen. I do.

First, the standard frame F5 at an unclear edge position
Are extracted as edge position candidates Ep1 and Ep2. Next, the positional relationship between the unclear edge position candidates Ep1 and Ep2 and the frames SF1 and SF2 having the clear edges Ef1 and Ef2 is determined. First, the distances La and Lb from the trailing edge fixed edge Ef1 of the head side fixed frame SF1 to the edge position candidates Ep1 and Ep2 of the unclear standard frame SF5 are determined. The leading edge Ef of the trailing edge side determined frame SF2 is also determined.
Edge position candidate Ep of standard frame SF5 that is indistinct from 2
The distances Lc and Ld to Ep1 and Ep2 are obtained. Then, of these distances La to Ld, the one having the smallest difference from the standard size is selected, and this is specified as the edge position of the image. In FIG. 7, since La is closest to the standard dimension,
The edge position candidate Ep1 that is a is specified as the determined edge Ef3. Next, the average length FLSave of one standard frame is added to the determined edge, and a position having this value is registered as the other determined edge Ef4.

In FIG. 8, the case where the undetermined image is a standard frame is described as an example. However, even in the case of a full panorama frame PF, the edge is similarly determined using FLPave and Gave. Further, even when a plurality of undetermined images are mixed, the edge position candidates of the undetermined frames are extracted and
Similarly, the edge is determined using FLSave, FLPave, and Gave. The edge position and size determined in this way are written to the memory of the setup unit 55.

FIG. 5 shows an example of the test screen on the display unit 51. (A) is a standard frame verification screen 65, and (B) is a full panorama frame verification screen 66.
In the case of a full panorama frame, the length of the full frame is almost twice as long as the standard frame.
As a result, the full panorama frame 68 is displayed longer and narrower than the standard frame 67. Therefore, the operator can easily know that the frame is the full panorama frame 68.

FIG. 9 shows a flowchart of a process for displaying the test screen. First, the size of each frame is read, and the test images 65 and 66 are sequentially displayed in the order of each frame number as shown in FIG. 5 according to the frame size. In the case of the standard frame, a test screen 65 as shown in FIG. 5A is displayed. In the case of a full panorama frame, a verification screen 66 as shown in FIG. 5B is displayed. The operator checks these verification screens 65 and 66 to determine whether the size and finish are appropriate. If the finish is not proper, the user operates the corresponding correction key to input a correction value.

If the size of the two standard frames is automatically determined to be a full panorama frame by mistake, two images are displayed as the full panorama frame 68 on the verification screen, so that the size is incorrectly determined. Can be easily known by the operator. In this case, a key for designating frame size change is operated. By this key operation, the corrected finished image is displayed again on the display unit 51 in a format for a standard frame as shown in FIG.

When the test is completed for all frames, an index image 70 is created as shown in FIG.
The recording image data of the index image 70 is sent to the laser printer 13. In the index image 70 shown in FIG. 10, unlike the verification screens 65 and 66, the standard frame thumbnail image 71
, And an index image 70 in which full panorama frame thumbnail images 72 are arranged in frame recording order. Therefore, a full panorama frame and a commonly used panorama frame (a frame recorded in the central area excluding the upper and lower areas of the standard frame and having the same length as the standard frame) are combined with the index image 70. Thumbnail images 71, 7
2 can be easily identified.

The thumbnail image of the full panorama frame 7
When 2 is a position where the index image 70 is divided over another line, the position is replaced with an adjacent standard frame. As a result, the full panorama frame thumbnail image 72 is not displayed as being divided.

The set-up section 55 calculates a cutting position for cutting the 135-type photographic film 18 into the film piece 18a based on the position information and the size information of each frame, and outputs the calculated position to the film cutting inserter 15. send.

The specification of the cutting position is performed based on a flowchart as shown in FIG. First, a position is determined where the film piece length (standard film piece length) for a predetermined number of frames, e.g., 6 standard frames, from the film tip (standard film piece length). If this position is located in the gap between the frames, The calculated cutting position is defined as a first cutting position. When the position of the film piece length for six frames is located in the frame, the middle of the gap between this frame and the frame preceding this frame is set as the first cutting position. Next, similarly, when the position corresponding to the film piece length for six frames from the first cutting position is located in the gap between the frames, the second
The cutting position is set, and when it is within the frame, the middle of the gap between the frame and the previous frame is set as the second cutting position. Hereinafter, similarly, a cutting position to be a standard film piece is obtained. When the remaining film length becomes less than the standard film piece length, the cutting position is specified so as to include the last frame. In this way, the photo film 18 is not cut off during the full panorama frame.

The film cutter cuts the photographic film based on the flow chart of the cutting process shown in FIG. First, the photographic film is fed, and the amount of the photographic film is counted. Then, the cutter is moved to the first position based on the film feed amount.
When the first cutting position reaches the cutter, the film feed is stopped, the cutter is operated, and the photographic film is cut and cut into pieces. Hereinafter, the standard frame 6 frames or 5 frames
The film is cut into pieces equal to the length of a frame. As shown in FIG. 2, the cut film piece 18a is put in a film sheath 19. Although the film cutting inserter 15 is used, a film cutter for simply cutting the film may be used. In this case, the film piece is manually inserted into the film sheath.

In the above embodiment, the registration frames SF1 and SF2 having adjacent fixed edges Ef1 and Ef2 are used when specifying the unclear edge position candidates Ep1 and Ep2, but the present invention is not limited to this. Alternatively, another registered frame at another remote position may be used. Also, using the fixed edge on the leading end, the leading edge of an unclear continuous frame is specified, and the trailing edge of the unclear continuous frame is also specified using the fixed edge on the rear end. Good. As described above, when the edge on the front end side or the rear end side is specified, by using the edge on the same side, the determination accuracy can be further improved.

When recording the frame number on the back side of the print photograph, the frame number bar code position is specified based on the prescan data. Then, the frame number bar code is analyzed for the first frame, and a frame number is obtained. The frame number of each frame image is assigned based on the analyzed frame number. If the frame number of the first frame cannot be read due to fog, dirt, or the like, the frame numbers of the other frame images are assigned based on the frame number that can be analyzed and the frame image on which the frame number is recorded. Also, in the case of a full panorama frame, since the frame is recorded over two frame numbers, a frame number having a smaller number may be used.

In the fine scan, image data of each frame is extracted from the fine scan data based on the position data of each frame specified by the pre-scan data. Then, based on the extracted image data, various types of image processing are performed, and print data after the image processing is output to a printer.

In the above embodiment, the position and size of the frame are specified based on the pre-scan image data. However, the position and size of the frame may be specified based on the fine scan image data.

In the above embodiment, the present invention is applied to a digital print system. In addition, the present invention is applied to an analog print system in which transmitted light of a photographic film is imaged on a photosensitive material by a printing lens and printed. May be. In this case, first, a prescan is performed, the position and size of each frame are specified based on the prescanned image data, and each frame is positioned at the printing position during printing based on the specified position data. Further, a film mask or the like is switched based on the size.

In the above embodiment, the photographic film in which the standard frame and the full panorama frame are mixed has been described.
In addition, the present invention may be applied to a photographic film in which a standard frame and a half frame having a length about half of the standard frame are mixed. In addition, the recording position and the size are determined based on the image data of one photo film. In addition, in the case of reorder printing, the recording position and the size are determined for each film piece. Is also good.

[0057]

According to the present invention, a means for taking in one image data of a photographic film, and a recording position and a size of an image frame having a clear edge are specified based on the one image data. A first specifying unit, and a second specifying unit that specifies a recording position and a size of an image frame whose edge is unclear based on the image frame and the size whose recording position and size are specified by the first specifying unit. Is provided, the recording position and size can be reliably specified even for an image frame having an unclear edge. In particular, even for a photographic film including a standard size and a different size in which the length in the film feed direction is changed from the standard size, the recording position and size of each frame can be automatically specified without fail. . In addition, by using the size determination result, the creation of an index image and the cutting process of cutting a photographic film into film pieces can be performed reliably.

Further, by changing the enlargement / reduction ratio between the standard size and the different size, an image is displayed so that both have substantially the same length, and a verification process is performed on the basis of this image.
When there is an erroneous determination of the size, this can be easily found. In addition, in response to a size change instruction input that is input while observing the display screen in the verification process, the image after the change instruction is displayed by changing the enlargement / reduction ratio, so that when there is an erroneous size determination. This can be easily corrected.
