Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film image reading apparatus, and more particularly, to an image on a developed photographic film,
The present invention relates to a device for performing main scanning and sub scanning by a line sensor.

[0002]

2. Description of the Related Art As a conventional film image reading device,
The developed photographic film is set in a state of being held in a holder, and the holder holding the photographic film is conveyed in a direction (sub-scanning direction) orthogonal to the element array direction (main scanning direction) of the line sensor, for example. Therefore, there is a system in which a recorded image on a film is read two-dimensionally (see Japanese Patent Application Laid-Open No. 1-105230).

A system has been proposed in which a color printer prints based on the image information (electrical signal) obtained by the reading, instead of the general printing in which the photographic film is directly exposed. . Further, in such a reading device, there is a configuration in which the read image information is subjected to various editing processes and then output to a printer or the like. In the editing work, a film image is roughly read (rough scan). When the editing processing conditions are determined using the image information, finer scanning (fine scanning) is performed, the image information obtained by the fine scanning is again edited, and the processing result is printed by the printer. (See Japanese Patent Laid-Open No. 2-105676, etc.).

[0004]

By the way, in reading a film image using the line sensor as described above, generally, the holder holding the film is conveyed (sub-scanning) from the start position of the sub-scanning and the reading is performed. When is finished,
Return the holder from the reading end position to the start position,
After that, the same scanning is performed again to perform reading.

Therefore, as described above, when both the rough scan and the fine scan are performed, it is necessary to perform two reciprocating movements in the sub-scanning direction per holder, which does not contribute to reading. There was a problem that it took much time to move to and the efficiency of reading was poor. Further, conventionally, a cassette for storing a plurality of holders is provided, and the holders are selectively supplied from the cassette to the transport table,
When reading is completed, collect the holder in the same cassette,
Since the feeding operation of another holder to the transport table is started at the stage when the collecting operation is completed, even if the transport table becomes empty, the next reading holder Since the selection / supply operation cannot be started, this also causes a decrease in reading efficiency.

The present invention has been made in view of the above-mentioned problems, and is an apparatus for reading image information of a film held in a holder by a line sensor for main scanning and sub-scanning, and performs rough scanning and fine scanning. It is an object of the present invention to improve the reading efficiency in a film image reading apparatus to be used.

[0007]

Therefore, in the present invention, while the developed photographic film held in the holder is scanned by the line sensor in the main scanning direction, the line sensor and the holder are relatively moved in the sub scanning direction. In the film image reading device that reads the image information of the photographic film by the line sensor, the movement in the sub-scanning direction is performed as a reciprocating motion to perform image reading in both the forward and backward sub-scanning. The rough image reading is performed in the forward sub-scanning, and the finer image reading is performed in the returning sub-scanning than in the forward sub-scanning.

Here, it is preferable to reverse the main scanning direction between the forward sub-scan and the return sub-scan. In addition, a carrier table that reciprocates in the sub-scanning direction with respect to the fixed line sensor is provided, and the holder is held by the carrier table to reciprocate the holder in the sub-scanning direction. When the transport table is at the start position of the forward sub-scan, the forward holder supply means for collecting the holder from the transport table and supplying the holder to the transport table; A return holder that collects the holders from the transport table at the end position of scanning, stores a plurality of the collected holders, and selectively supplies the holders to the transport table from the plurality of stored holders. It is advisable to provide storage means.

[0009]

According to the film image reading device having such a structure, in the structure in which the image of the film held in the holder is read by the main and sub-scanning by the line sensor, the film is reciprocated in the sub-scanning direction, and a rough image is obtained during the forward sub-scanning. Reading (rough scan) is performed, and finer image reading (fine scan) is performed during the return sub-scan. Therefore, it is possible to reduce movement in the sub-scanning direction that does not contribute to reading, as compared with the case where both the rough scan and the fine scan are performed by the sub-scanning in the forward direction.

Incidentally, the fine image reading in the sub-scan returning includes a structure in which after a predetermined frame is selected, the image of the selected frame is read in the same main scanning and sub-scanning directions as in the rough scan scanning. In addition, as described above, when the image reading is performed in both the forward sub-scan and the backward sub-scan, if the main scanning direction by the line sensor is reversed by the sub-scanning direction, the forward sub-scanning is performed. The data order of the read image data and the image data read by the return sub-scan is reversed. Therefore, for example, if the image data read in the return sub-scan is sequentially stored, and the print data is read out in the reverse order of the writing order, the same image as the image read in the forward sub-scan can be obtained. Therefore, the processing after reading can be easily performed.

Further, the line sensor is fixed, the holder is held on the transport table and reciprocated in the sub-scanning direction, and when the transport table is located at the start position of the forward sub-scan, the return sub-scan is performed. The holder that has finished reading is collected from the transport table, and the holder to be read by the forward sub-scan is supplied to the transport table. On the other hand, when the transport table is at the end position of the forward sub-scan, the holder that has been roughly read by the forward sub-scan is collected from the transport table, and a holder for performing fine reading is newly added to the transport table. Supply.

Therefore, a holder different from the holder that has been rough-scanned in the forward sub-scan is made to perform a fine scan in the returning sub-scan, or a rough scan of a plurality of holders is sequentially performed so that the holder that has been rough-scanned is selected. It is possible to make a plurality of standbys at the end side of the forward sub-scanning, in other words, at the start position of the returning sub-scanning, and selectively perform the returning sub-scanning for the holders requiring fine scanning. For example, it becomes possible to start the holder supply operation at the start position side while performing the holder recovery operation at the forward end position side.

EXAMPLES Examples of the present invention will be described below. Figure 1
1 is a perspective view showing a first embodiment of a film image reading device according to the present invention. In FIG. 1, the developed photographic film 1 is held by a holder 2 for a predetermined number of frames (for example, 6 frames). As shown in FIG. 2, the holder 2 is formed by connecting an upper frame 2a and a lower frame 2b, each of which has an opening facing a recording surface of a film to be held, in a hinged manner. It is sandwiched and held between the frame 2a and the lower frame 2b.

The photographic film 1 may be a slide (positive film) separated by one frame, or a roll-shaped negative film cut into a predetermined number of frames. It is preferable to prepare two types of holders (a holder for negative) for holding a continuous film and a holder (a holder for slide) for holding the separated film for each frame.

The holder transport table 3 is for mounting the holder 2 and moving it in the sub-scanning direction. The holder transport table 3 is supported by a pair of shafts 4 so as to be reciprocally movable. The holder transport table 3 is guided by the shafts 4 to reciprocate, whereby the holder 2 is moved.
The film 1 set in (1) reciprocates linearly (in the sub-scanning direction) on the same plane.

The holder transfer table 3 has a shaft 4
Is fixed in the middle of a drive belt 7 wound between a drive-side pulley 5 and a driven-side pulley 6 that are arranged so as to face each other in the extending direction, and move according to the movement of the drive belt 7. . The drive pulley 5 includes a stepping motor, a reduction gear (not shown), a motor position sensor 10 including a photo sensor 8 and a slit disk 9 provided for detecting the rotational position of the stepping motor, and the like. It is configured to be rotationally driven by a sub-scanning drive unit 11 including the above.

A table origin marker 3a is provided on the holder transport table 3, and the marker 3a is provided.
Is detected by a photo sensor 12 provided at a predetermined position in the extending direction of the shaft 4. Then, the marker 3a is detected by the photo sensor 12,
Further, the state in which the slit of the slit disk 9 is detected by the photo sensor 8 is determined as the origin position of drive control (start position of forward sub-scanning).

On the other hand, as a reading system in the main scanning direction, a halogen lamp 13, a condenser mirror 14, and a condenser lens 15 are provided below the holder 2 set on the holder transport table 3 in the direction orthogonal to the film surface. Then, the illumination light of the halogen lamp 13 is collected by the condenser mirror 14 and the condenser lens 15 and applied to the film 1 held by the holder 2.

The light (transmitted light) transmitted through the film 1 and carrying the image information is passed through the reading lens system 16 having a diaphragm and the filter device 17 in the reciprocating direction (sub scanning direction) of the holder transport table 3. CC in the orthogonal direction (main scanning direction)
An image is formed on the color line sensor 18 (one-dimensional image sensor) in which a plurality of photoelectric conversion elements such as D are arranged. The filter device 17 includes a color correction filter 19 used when the photographic film 1 to be read is a negative film and an ND filter 20 used when the photographic film 1 is a positive film. These filters can be selectively positioned on the optical path by the configuration of rack teeth 22 provided on the filter frame 21 and a motor 24 that rotates pinion teeth 23 that mesh with the rack teeth 22. Has become.

Here, by detecting the position detection marker 21a provided on the filter frame 21 by the photo sensor 25, the mounting state of the filter can be detected. With the above structure, the photographic film 1 held by the holder 2 is scanned in the main scanning direction by the color line sensor 18 and moved in the sub-scanning direction which is a direction orthogonal to the element row of the fixed color line sensor 18. As a result, the recorded image is read two-dimensionally.

On the other hand, holder supply / recovery mechanisms 26, 27 for supplying the holder 2 to the holder transfer table 3 and for recovering the holder 2 placed on the transfer table 3.
Are provided at both ends of the transport table 3 in the moving direction. The holder supply / recovery mechanisms 26, 27 include a cassette 28 for accommodating a plurality of holders 2, an elevating mechanism 29 for elevating the cassette 28 in the vertical direction in the figure, and selectively pushing out the holder 2 accommodated in the cassette 28. The push-out mechanism 30 and the pull-in mechanism 31 that pulls the holder 2 on the holder transport table 3 into the cassette 28 and collects it.

The cassette 28 accommodates a plurality of holders 2 in a state where the film surfaces held by the holders 2 are laminated in parallel with each other, and each of the holders 2 can be pulled out in the longitudinal direction of the holder 2 in parallel with the film surface. It is like this. In order to hold the left and right sides of the holder 2 in the longitudinal direction for the stacked storage, a holding groove 28a is formed in the cassette 28, and both sides of the holder 2 in the longitudinal direction are open surfaces.

The elevating mechanism 29 elevates and lowers the table 32 on which the cassette 28 is placed by being driven by a motor 33. Further, the pushing mechanism 30 includes a plate-shaped pushing member 34 and a transport mechanism 35 that reciprocates the pushing member 34 in parallel with the sub-scanning direction. The pushing mechanism 30 is mounted on the table 32 of the lifting mechanism 29. The cassette 28 is placed on the side opposite to the transport table 3 side.

Here, the pushing member is pushed by the pushing mechanism 30.
When the 34 is moved toward the transport table 3 and pushed into the cassette 28, the holder 2 among the plurality of holders 2 housed in the cassette 28, which has the same height position as the pushing member 34, is located behind the holder 2. Only the end surface is pushed by the pushing member 34, and only the holder 2 is pushed out from the open surface on the side of the conveying table 3 toward the side of the conveying table 3 in the sub-scanning direction.

Therefore, after the cassette 28 is moved up and down so that the height of the holder 2 to be pushed out by the elevating mechanism 29 and the height of the pushing member 34 are matched, the pushing member 34 is moved in the direction of the carrying table 3 by the carrying mechanism 35. By doing so, the desired holder 2 can be selectively pushed out of the cassette 28. In addition, the retracting mechanism 31 is a roller pair.
The holder 2 held on the transport table 3 is gripped by the 36, and is fed to the cassette 28 side by the rotation of the roller. At this time, the elevating mechanism 29 also causes the empty stage of the cassette 28 and the holder by the retracting mechanism 31. By matching the conveyance height with the conveyance height, the read holder 2 can be stored at the intended position.

The pull-in mechanism 31 holds the holder 2 pushed out of the cassette 28 by the push-out mechanism 30 by the pair of rollers 36, and drives the rollers in the direction opposite to the pull-in direction, whereby the transport table 3 is moved. It also sends it to. Further, 37 is a photoelectric switch attached to the retracting mechanism 31, and the photoelectric switch 37 can detect the holder 2 to control the rotation drive of the roller and the gripping operation by the roller pair.

Further, 38 is a holder sensor for detecting the height of the cassette 28 and for detecting the presence or absence of the holder 2 in the cassette 28. As described above, the holder supply / recovery mechanisms 26 and 27 are configured by the same mechanism, but in the present embodiment, only the cassette 28 on the holder supply / recovery mechanism 26 (forward holder supply means) side is removable. The cassette 28 on the holder supply / recovery mechanism 27 (return holder storage means) side is not attached or detached.

Then, the holder 2 holding the film 1 to be read is stored in the cassette 28,
Preparation for reading is performed by setting 28 on the holder supply / collection mechanism 26 side, and the holder 2 after reading (rough scan and fine scan) is stored in the cassette 28 on the holder supply / collection mechanism 26 side. In this state, the cassette 28 and the cassette 28 are taken out from the apparatus.

Incidentally, both cassettes 28 of the holder supply / recovery mechanisms 26 and 27 may be detachable. Here, FIG. 3 shows an example of the external appearance of the reading device in the case where only the cassette 28 on the holder supply / recovery mechanism 26 side is attached and detached as described above. In FIG. 3, a cassette insertion opening 41 and a liquid crystal touch panel 42 for operation are provided on the table of the apparatus body 40.
And are provided. Also, the first CR for displaying the input image
T43 and a second CRT 44 for displaying an output image are provided side by side, and a work image is selected from the images (read images) displayed on the first CRT 43, and the result of editing the selected image is It can be visually checked and confirmed on the second CRT 44.

A printer 46 having a scanner 45 for reading a reflection original is connected to the reading device 40, and image information corresponding to an image displayed on the second CRT 44 (edited image). Is the printer 46
It is a configuration that is output to and printed. That is, the image of the photographic film 1 held in the holder 2 is read, various editing processes such as trimming and color correction are performed on the read image information, and the film image is read again when the editing process conditions are determined. The printer 46 prints the image after performing image processing based on the determined conditions.

In the first reading, high image quality is not required because it is sufficient to grasp the image of the set film and to easily visually confirm the result of the image editing process. Therefore, in the first reading, a relatively rough reading (hereinafter referred to as a rough scan) is performed by increasing the sub-scanning speed or thinning out the read pixel data, but finally the printer 46. In order to obtain the image information to be output to, the high image quality is required, and thus the rough scan is made to perform finer reading (hereinafter referred to as fine scan).

Here, in the configuration shown in FIG. 1, the rough scan is performed by the forward sub-scan from the holder supply / recovery mechanism 26 side (origin position) toward the holder supply / recovery mechanism 27 side, and the rough scan is completed. The holder 2 is temporarily collected and stored in the cassette 28 on the holder supply / collection mechanism 27 side. Then, the holder 2 taken out from the cassette 28 on the holder supply / recovery mechanism 27 side is finely scanned by sub-scanning for returning to the original position from the holder supply / recovery mechanism 27 side.

Next, the rough scan by the forward sub-scan and the fine scan by the return sub-scan will be described.
The details will be described according to the routines shown in the flowcharts of FIGS. In the flowcharts of FIGS. 4 to 7,
First, in step 1 (denoted as S1 in the figure; the same applies hereinafter), first, the cassette on the holder supply / recovery mechanism 26 side.
In order to sequentially take out the holders 2 set in 28 (the cassette A in FIG. 1 and the cassette 28 on the holder supply / collection mechanism 27 side will be described as the cassette B), it is at the initial lowest position. The cassette A is raised stepwise.

In step 2, it is determined whether or not the holder 2 exists at the holder take-out height at the raised position of the cassette A. When the presence of the holder 2 is confirmed, the process proceeds to step 3 and it is determined whether or not the holder 2 is at a height position where the holder 2 can be pushed out and taken out. If the holder 2 can be taken out from the cassette A, the completion of the rough scan of the holder 2 previously sent out from the cassette A is waited in step 4. Once the rough scan is complete, step 5
Then, the holder 2 for performing the rough scan is attached to the pushing member 34.
Then, the next reading holder 2 is supplied to the transport table 3 by pushing it into the transport table 3 side.

That is, all the holders 2 housed in the cassette A are to be rough-scanned.
As will be described later, the holder 2 that has been taken out of the cassette A and finished the rough scan is recovered from the rough scan end position to the cassette B side, and then the rough scan is performed from the cassette B side to the empty return table 3. The holder 2 for performing the above is supplied.

Here, since the holder 2 that has been rough-scanned is not returned to the cassette A side, the holder 2 to be next rough-scanned is searched for on the cassette A side during the rough scan, and the next time the rough scan is completed, Since the holder 2 can be supplied to the transport table 3, it is possible to efficiently supply the holder 2 for the rough scan to the transport table 3.

When it is determined in step 6 that the supply of the holder 2 to the transport table 3 is completed, the process proceeds to step 7 to start the rough scan of the holder 2 while returning to step 1 again to set the cassette A step by step. While raising the holder, find the holder 2 to be read next. On the other hand, in parallel with the above-described processing for sending out the holder 2 to be sequentially read from the cassette A side, processing for collecting the holder 2 for which the rough scan has been completed on the cassette B side is performed.

In step 9, in order to find an empty space for collecting and storing the rough-scanned holder 2 in the cassette B, a process of raising the cassette B stepwise is performed. Then, in step 10, it is determined whether or not the holder 2 is present at that position. If the cassette B is not full of the holder 2 (step 11) and there is an empty space for accommodating the holder 2, rough scanning is performed at that position. Wait for the end (step 12).

When it is determined in step 8 that the rough scan is completed, it is determined in step 13 whether or not there is an empty space on the cassette B side. If there is an empty space, the process proceeds to step 14 and the cassette The holder 2 which has been taken out from the A side and finished the rough scan is placed in the cassette B.
Collect and store in the empty space. Further, the images read by the rough scan are sequentially arranged on the first CRT 43 and displayed in a list (index display) as shown in FIG. 8 (step 15).

Here, the holder 2 which has finished the rough scan
If there is no empty space on the cassette B side in which the cassette can be collected, the process proceeds to step 16 and an alarm is displayed on the CRT display screen to warn that there is no empty space in the cassette B. As described above, the holder 2 is sequentially taken out from the cassette A side, a rough scan (forward sub-scanning) is performed, and the holder 2 after the reading is recovered to the cassette B side.

When it is determined in step 17 that the rough scan has been completed for all the holders 2 accommodated in the cassette A, the process proceeds to step 18. Step
At 18, the completion of rough scan (index reading) is displayed on the first CRT 43 (see FIG. 9). When all the rough scans for all the holders 2 are completed, various image editing operations are performed based on the image information obtained by the rough scans (step 19), and finally the image to be output to the printer 46 and printed is printed. Make a decision.

Examples of the editing work include simultaneous printing of a plurality of images, image composition, upside down, trimming, and color correction. Print multiple images (Album print)
In the case of performing, as shown in FIG. 10, on the liquid crystal touch panel (LCD) 42, a display (image No. designation) for selecting the image layout of the album print corresponding to the image displayed on the first CRT 43 is displayed. (Switch display) is performed so that any image can be selected as an album print, and the selected image is displayed on the second CRT 44.

Further, in the case where the upside down is performed, FIG.
As shown in, a switch for reversal processing is displayed on the liquid crystal touch panel (LCD) 42, a state before processing is displayed on the first CRT 43, and a processed result is displayed on the second CRT 44. Furthermore, when performing trimming processing,
As shown in FIG. 12, display for frame setting and magnification setting is performed, the frame setting state is displayed on the first CRT 43, and the trimming processing result is displayed on the second CRT 44.

Further, in the color correction, as shown in FIG. 13, a switch display for designating the correction color and the correction portion is displayed on the liquid crystal touch panel (LCD) 42, and the designation state is displayed on the first CRT 43 together with the image. , The color correction result is the second
Displayed on CRT44. When the editing process is completed and the image to be finally output to the printer 46 and the editing process content corresponding to the image are determined, the holder 2 containing the corresponding frame from the plurality of holders 2 accommodated in the cassette B side. Is selected (step 20), and the height position of the holder 2 is adjusted to the transport height by the vertical movement of the cassette B (step 2).
1) A process of pushing out the holder 2 to supply it to the transport table 3 is executed (step 22).

Then, the holder 2 is returned from the cassette B side to the cassette A side, and the fine scan of the corresponding frame is performed by the sub-scan (step 23). In step 24, the image read by the fine scan is subjected to the second CR.
Display it at T44 (see FIG. 14). The holder 2 that has been taken out of the cassette B and completed the fine scan (return sub-scan) is recovered to the cassette A side.
It is determined whether or not there is a space on the side (step 25), and if there is no space, the process proceeds to step 26, and an alarm warning that the fine-scanned holder cannot be collected is displayed on the CRT screen. .

When the fine scan of the designated frame is completed (step 27), the image information obtained by the fine scan is edited in response to the result of the editing work in the step 19 (step 28), and the edited image is processed. Information is temporarily stored as a print image (step 2
9). Then, if there are more designated frames on the film held in the same holder 2, the fine scan of that frame is executed, and if it is determined in step 30 that all the designated frames have been fine-scanned by the same holder 2, Step 31
Then, the process proceeds to and the holder 2 that has completed the fine scan is collected and stored in the cassette A side.

When it is determined in step 32 that there are remaining designated pieces for fine scanning, in addition to the holder 2 which has finished fine scanning, the process returns to step 20 and the holder 2 including the designated pieces is replaced. The process of searching from the cassette B side and fine scanning the designated frame is repeated. Then, when the fine scan is completed for all the designated frames, the image information obtained by the fine scan is output to the printer 46 in step 33 and printing is performed. Instead of printing, the electronic filing device may be configured to file the image information.

When the output to the printer is completed, a process of returning the cassettes A and B and the holder 2 to the initial state is performed (step 34), and the first CRT 43 is made to display that all the processes are completed (step 35). Here, in this embodiment, since only the cassette A is configured to be detachable,
For the holder 2 left on the cassette B side without being fine-scanned, the operation of returning the holder 2 to the cassette A side via the transport table 3 is performed during printing, and finally, the cassette B is emptied and placed on the cassette A side. It is advisable to collect and store the holder 2 as in the state before reading.

As described above, if the fine scan is performed in the return sub-scan from the cassette B side, the fine scan is performed by one sub-scan as compared with the case where the fine scan is performed in the forward sub-scan from the origin position. Therefore, the sub-scanning operation can be saved and the total processing time can be shortened. In addition, as described above, when the image is read in each of the forward sub-scan and the backward sub-scan,
As shown in FIG. 15, different image readings in the sub-scanning direction are performed on the same image. Here, the main scanning direction by the color line sensor 18 is defined as the forward sub-scan and the return sub-scan. It is preferable to reverse by.

If the main scanning direction is reversed in this way,
Since the image data in the return sub-scan is obtained in the reverse order of the order of the image data read in the forward sub-scan, for example, the order of the image data read in the forward sub-scan may be a normal order. For example, by reading the image data obtained by the backward sub-scan in the order reverse to the writing order from the memory, the same image as the image obtained by the forward sub-scan can be obtained, and the post-processing can be performed. Is easy.

By the way, in the above embodiment, the cassettes 28 for accommodating the plurality of holders 2 are arranged at the starting point side of the forward scanning and the starting point side of the returning scanning (the ending point of the forward scanning), respectively, and the cassette A All the films respectively held in the plurality of holders 2 stored on the side are rough-scanned, and this rough scan is performed, and the fine scan is performed by selectively returning from the plurality of holders 2 stored on the cassette B side. I made it happen.

However, a configuration may be adopted in which one holder 2 is roughly scanned in the forward sub-scan and fine-scanned in the return sub-scan while it is placed on the transport table 3. In this case, on the transport table 3. Since the forward sub-scanning and the backward sub-scanning are performed in series with the holder 2 still mounted on, the unnecessary movement in the sub-scanning direction without reading can be eliminated.

When processing the holders 2 one by one as described above, the cassette 28 is used as in the second embodiment shown in FIG.
Also, a mechanism for selectively taking out the holder 2 from the cassette 28 can be omitted. In the configuration shown in FIG. 16, the forward sub-scanning start side (the origin position side of the transport table 3).
In addition, a holder transport mechanism 50 for placing the holder 2 supplied by hand on the transport table 3 and for removing the holder 2 on the transport table 3 and discharging it is provided.

The holder transfer mechanism 50 is composed of a drive roller 51 driven by a motor, a transfer roller 53 including a driven roller 52, and a holder tray 54.
When the holder 2 is inserted along the path 54, the carrying roller 53
The holder 2 is gripped by the holder 2 and placed on the transport table 3, and the holder 2 placed on the transport table 3
Is held by the carrying roller 53 and sent to the holder tray 54 side.

The forward sub-scanning (rough scan) and the returning sub-scanning (fine scan) using the system having the configuration shown in FIG. 16 will be described according to the routine shown in the flowchart of FIG. In the flowchart of FIG. 17,
First, in step 51, the holder 2 for reading is loaded and set on the transport table 3.

Next, the holder 2 is transported from the scanning origin position on the holder transport mechanism 50 side in the forward sub-scanning direction, which is the direction away from the transport mechanism 50, and the rough scan is performed (step 52). Images read by such rough scan are displayed side by side on the CRT (index display)
(Step 53).

When the rough scan is completed for each frame of the film 1 held by the holder 2 (step 54), the transport table 3 is stopped at the end point of the forward sub-scan, and the rough scan is read in this state. Multiple frames (maximum 6 if the number of frames held in the holder 2 is 6, for example)
An operation for designating an output image is performed from among the above, and only the designated image is enlarged and displayed on the CRT (step 5
Five).

In the configuration shown in FIG. 16, the holders 2 are processed one by one, and the number of images handled in one operation is 6
Since it is about one sheet, as shown in FIG. 18, display characters indicating that a rough scan (index reading) is in progress and a list of images read by the rough scan are displayed on the same screen. In specifying the output image, as shown in FIG. 19, the list of read images and the enlarged display of the specified image may be performed on the same screen.

Next, various editing operations such as color correction and trimming are performed on the designated output image based on the image information obtained by the rough scan (step).
56). In such editing work, as in the color correction work state shown in FIG. 20 and the trimming work state shown in FIG. 21, the index display, the designated image display, and the processing result image display may be simultaneously performed on the same screen.

When the editing processing conditions are determined, the fine scan for finely reading the designated frame again for output to the printer is moved from the end point of the forward sub-scan toward the origin position on the transport mechanism 50 side, and the holder 2 is moved. It is carried out by the sub-scan of the return which is carried out (step 57). When the transport table 3 is returned to the origin position on the transport mechanism 50 side by the return sub-scan (step 58), the image information read by the return sub-scan (the result of editing the image information) is output to the printer 46. (Step 60), holder 2 that has finished reading
Is taken out from the carrying table 3 and discharged onto the holder tray 54 (step 61).

If the transport table 3 cannot be returned to the original position by the return sub-scan, an alarm is displayed (step 59) and the holder 2 is further transported in the return sub-scan direction. That is, in the configuration shown in FIG.
Coarse reading (rough scan) in the sub scanning from the 50 side
Then, the holder 2 is stopped at the end point of the forward sub-scanning, the designated frame is finely read by the returning sub-scanning (fine scanning), and the holder 2 after the returning sub-scanning is taken out. To do.

Therefore, the number of frames that can be handled in one operation is limited to the number of frames held by the holder 2 without the transport table 3 moving in the sub-scanning direction in an empty state. There is no movement in the direction, and work can be done efficiently. Further, the first embodiment in which the cassette 28 is provided on each of the start side of the forward sub-scan and the start side of the return sub-scan (the end side of the forward sub-scan) and the holder 2 without the cassette 28 at all. In combination with the second embodiment in which the holders 2 are processed one by one, the holders 2 are manually fed one by one, but the holders 2 after the rough scan are collected at the end point of the forward sub-scan and the cassette 28 ( A plurality of cassettes B) may be stored.

FIG. 22 shows a third embodiment having such a structure. In FIG. 22, the holder carrying mechanism 50 in the second embodiment described above is provided on the side of the origin of the sub-scan, and the end point side of the forward sub-scan shown in FIG. 1 of the first embodiment. The holder supply / recovery mechanism 27 shown is provided. Then, the holders 2 inserted one by one from the transport mechanism 50 side are rough-scanned by the sub-scan on the way to the holder supply / collection mechanism 27, and the holders 2 after the rough scan are collected in the cassette 28 (cassette B).・ Stored.

When the holder 2 for the rough scan remains, the carrier table 3 is returned to the original position in the empty state and the full scan is performed again. When the rough scan of all the holders 2 to be read is completed, the holder 2 including the designated output image (designated frame) is taken out from the cassette 28 and placed on the transport table 3 as in the first embodiment. The fine scan is executed by the sub-scan returning to return the holder 2 to the transport mechanism 50 side.

Further, in the first embodiment, the holder 2 is linearly moved along the longitudinal direction thereof so that the carrier table 3 is moved.
However, in such a configuration, since the device becomes long in the sub-scanning direction, as shown in the fourth embodiment of FIG. 23, for example, on the origin side of the sub-scanning, It is also possible to provide a storage / transport mechanism for the holder 2 on the side of the transport table 3 and move the holder 2 in a direction orthogonal to the sub-scanning direction with respect to the transport table 3.

In FIG. 23, a holder supply / recovery mechanism 26 '
One side surface of the cassette 28 'that is set to is an open surface, and by raising and lowering the cassette 28' by the elevating mechanism 29, an arbitrary holder 2 stored in the cassette 28 ' The transfer arm 61 of the transfer mechanism 60 is aligned. Then, the transfer arm 61 linearly extends toward the transfer table 3 (in the main scanning direction) while holding the protrusions provided at both ends of the holder 2 in the longitudinal direction, so that the cassette 28 'is formed. The stored holder 2 is selectively taken out, and the taken-out holder 2 is placed on the transport table 3. Similarly, the arm is held with the holder 2 placed on the carrying table 3 being held.
By contracting 61, the holder 2 is collected on the predetermined stage of the cassette 28 '.

The holder 2 is placed on the carrying table 3 and
Further, the mechanism / arrangement for collecting the holder 2 from the transport table 3 is not limited to the above, and the configuration of the reading optical system is not limited to that of the above embodiment.

[0068]

As described above, according to the film image reading apparatus of the present invention, for example, the editing work is performed based on the image information obtained by the rough reading (rough scan), and the finer reading is performed at the final output. In a configuration in which (fine scanning) is performed and output to a printer or the like, by using the forward sub-scan and the backward sub-scan respectively,
It is possible to reduce the movement in the sub-scanning direction that does not involve reading and improve the reading efficiency.

Further, since the direction of the main scanning is reversed between the forward sub-scan and the backward sub-scan, the subsequent image information processing can be simplified even if the sub-scan direction is different. effective. Further, by providing a means for collecting and storing a plurality of cassettes at the end position of the forward sub-scan, that is, the start side of the return sub-scan, it is possible to reduce unnecessary movement of the plurality of holders in the sub-scanning direction. The effect is that they can be processed collectively.
