Description

  The present invention relates to an image reading apparatus capable of reading an image formed on a document.

  2. Description of the Related Art Photographic processing apparatuses capable of automatically performing processing such as exposure, development, bleach-fixing, and stabilization on photosensitive materials such as photographic paper are known. When exposing a photosensitive material with such a photographic processing apparatus, direct (analog) exposure is widely performed in which the photosensitive material is exposed with light transmitted through a photographic film. On the other hand, in recent years, a photosensitive material is exposed with light controlled based on a digital image data file (image signal) obtained by imaging a film with a film scanner having an image sensor such as a CCD sensor. Digital exposure is in practical use. By adopting the digital exposure method, various image processing such as color correction, density correction, and sharpening processing can be performed with a high degree of freedom, and quick reprint processing is possible, and color and density reproducibility is also possible. In addition, it is possible to obtain an excellent print with higher resolution and higher resolution.

  Patent Document 1 describes a film scanner having both a one-time scanning mode and a two-time scanning mode. The one-time scanning mode is a mode in which all frames in one film are continuously read at a magnification suitable for creating a reference size print. In the double scanning mode, first, all frames in a film are read continuously at a low magnification (press scanning), and then the film is at a magnification suitable for creating a print of a size arbitrarily selected by the operator. This mode reads all the frames one by one (main scanning). Note that the size of the thumbnail image file related to each frame generated by reading in the press scanning is sufficiently smaller than the size of the image data file related to each frame generated by reading in the one-time scanning mode. .

  In the one-time scanning mode, all the image data files related to the generated one film are stored in the memory. At this time, no image data file stored before that is stored in the memory until the last image data file is stored. That is, the memory has a capacity larger than the sum of the sizes of all the image data files. Thereafter, a thumbnail image is displayed on the display based on the read image data file that has been subjected to the thinning process. The operator performs a pre-judgment operation to input a correction value, the number of prints, and the like for each frame while confirming the thumbnail image. Then, after the pre-judgment work is completed, an exposure process for photographic paper is started based on the image data file.

  In the twice scanning mode, thumbnail images are displayed on the display based on all the thumbnail image files relating to one film generated by press scanning and stored in the memory. Then, after the pre-judgment work for all the frame images by the operator is finished, the main scanning is started, and the image data files generated by reading are sequentially stored in the memory. At this time, the exposure process for the photographic paper is started from the frame read by the scanning, and the image data files relating to the frames for which the exposure process has been completed are sequentially deleted from the memory. This is because the size of the image data file generated in this scanning is often relatively large, so that it may not be possible to store all of them in the memory.

Therefore, the one-time scanning mode is high in that the number of readings is one, and the next film can be set on the scanner immediately after the reading of all the frames for one film is completed. Indicates processing capacity. In the two-time scanning mode, the processing capability is reduced by an increase in the number of times of scanning compared to the one-time scanning mode. Each frame can be read at a high magnification. This makes it possible to obtain a high quality print even when the print size is large.
JP 2003-125158 A

  In such a film scanner, whether the film is read in the scanning mode once or the film is read in the scanning mode twice is automatically determined according to the print size. Specifically, when the print size exceeds the reference size (the maximum size suitable for the reading magnification in the once scanning mode), the film is read in the twice scanning mode.

  Therefore, even when the print image may have a low image quality, for example, when performing a test print, the scanning mode is automatically selected twice, and the processing capability of the film scanner may be reduced.

  A preferred embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a schematic configuration of a film scanner according to the present embodiment.

  As shown in FIG. 1, a film scanner 1 includes a film mounting unit 110 on which a film is mounted, and an illumination optical unit 120 that is disposed above the film mounting unit 110 and irradiates light on the film during scanning. The reading unit 10 includes an imaging optical unit 130 that is disposed below the film mounting unit 110 and receives light emitted from the illumination optical unit 120 and transmitted through the film mounted on the film mounting unit 110. .

  Further, the film scanner 1 includes a controller 20 that controls the entire film scanner 1, a display 31 that displays various information related to the film scanner 1 and notifies the operator, and a keyboard 32 that gives instructions to the film scanner 1. And a mouse 33.

  Here, the detailed configuration of the reading unit 10 will be described with reference to FIG. 2 showing the internal configuration of the reading unit 10 of FIG.

  The film mounting unit 110 determines the irradiation range of the light emitted from the illumination optical unit 120 for the mounted film, and moves the film in the sub-scanning direction (the arrow direction shown in FIG. 2) by the plurality of conveying roller pairs 112. Transport at a constant speed. Further, the film mounting unit 110 has a width for detecting the width of the film mounted on the film mounting unit 110 on the upstream side in the film transport direction from the position corresponding to the optical path of the light emitted from the illumination optical unit 120. A detection sensor 111 is arranged.

  The illumination optical unit 120 is for irradiating the film conveyed in the film mounting unit 110 with light. The illumination optical unit 120 includes a light source 121, a light control filter 122, and a mirror tunnel 123. The light source 121 is, for example, a halogen lamp, and light emitted from the light source 121 includes light in a wavelength region corresponding to each of the three colors of red (R), green (G), and blue (B). . The dimming filter 122 is for adjusting the color distribution of the light beam from the light source 121 as necessary. The mirror tunnel 123 is for adjusting the intensity distribution of the light beam from the light source 121. Therefore, the light emitted from the light source 121 is irradiated on the film after its color distribution and intensity distribution are adjusted by the light control filter 122 and the mirror tunnel 123.

  The imaging optical unit 130 performs various processes on the lens unit 131 including a zoom lens, CCD line sensors 132a, 132b, and 132c that receive light transmitted through the film, and data output from the CCD line sensors 132a to 132c. And a data processing unit 133 to perform.

  The lens unit 131 is for imaging the light transmitted through the film on the CCD line sensors 132a to 132c. In FIG. 2, only one lens is illustrated as the lens unit 131 that functions as the imaging optical element, but the lens unit 131 may include a plurality of lenses.

  The CCD line sensors 132a to 132c are line-shaped sensors arranged along the main scanning direction orthogonal to the sub-scanning direction that is the film transport direction. Here, the CCD line sensors 132a to 132c include a large number of pixels arranged in parallel with the main scanning direction, that is, the film width direction. Further, the CCD line sensors 132a to 132c are arranged apart from each other by a predetermined distance from the upstream side in the sub-scanning direction to the downstream side.

  One of R, G, and B color separation filters is attached to each imaging surface of the CCD line sensors 132a to 132c, and is assigned to correspond to each color of RGB. That is, a color filter that passes only the red component of the light transmitted through the film is passed through the imaging surface of the CCD line sensor 132a corresponding to red, and similarly, a green color is applied to the imaging surface of the CCD line sensor 132b corresponding to green. A color filter that allows only the component to pass is attached to the imaging surface of the CCD line sensor 132c corresponding to blue.

  The data processing unit 133 samples and holds the pixel signals output from the pixels of the CCD line sensors 132a to 132c, thereby converting the pixel signals into continuous image signals, and converting the pixel signals to a predetermined number of bits ( After being converted into a digital signal (for example, 12 bits), it is supplied to the controller 20 as a digital image data file.

  Next, the controller 20 will be described with reference to FIG. 3 which is a block diagram showing the configuration of the controller 20. As shown in FIG. 3, the controller 20 includes a mode setting unit 21, a mode storage unit 22, a mode rewriting unit 23, a reading control unit 24, a reading magnification storage unit 25, a reading magnification rewriting unit 26, an image storage unit 27, and An image processing unit 28 is included. The controller 20 is connected to an exposure head 101 that performs an exposure process on photographic paper that is a photosensitive material in order to print an image read by the film scanner 1.

  The mode setting unit 21 sets a default scanning mode stored in the mode storage unit 22. In the present embodiment, the mode setting unit 21 sets a single-time scanning mode, which will be described later, as the default scanning mode. The mode storage unit 22 stores a scanning mode when the reading unit 10 reads a film. In the present embodiment, the mode storage unit 22 stores any one of three scanning modes, which will be described in detail later: a once scanning mode, a quality priority twice scanning mode, and a capability priority two times scanning mode. . More specifically, the mode storage unit 22 stores one of the scanning modes for each print channel. In the initial state, the mode storage unit 22 stores the one-time scanning mode set by the mode setting unit 21.

  A print channel is a combination of a plurality of print conditions. In the present embodiment, the name, width (length in the print width direction), feed (length in the print longitudinal direction), WB / BL (with / without border) and scanning mode are determined for each print channel. It has been. The name, width, feed, and WB / BL of each print channel can be freely set by the operator on the print setting screen 50 described later.

  Here, the print channel selection screen 40 and the print channel setting screen 50 will be described with reference to FIG. 4A shows a print channel selection screen 40, and FIG. 4B shows a print channel setting screen 50.

  The print channel selection screen 40 is displayed on the display 31 before the film scanner 1 starts reading the film, and more specifically, before the film is set in the film mounting unit 110. As shown in FIG. 4A, the print channel selection screen 40 displays a list of setting contents of a plurality of preset print channels.

  On the print channel selection screen 40, when the operator clicks the right or left button of the mouse 33 with the cursor of the mouse 33 placed on one of the displayed print channels, the print channel setting screen is displayed. 50 is displayed on the display 31.

  On the print channel setting screen 50, as shown in FIG. 4B, a name input field 51, a width input field 52, and a feed input field 53 into which a name, width, and feed can be input are displayed. The print channel setting screen 50 displays a WB / BL and a WB / BL display field 54 for displaying a scanning mode, and a mode display field 55. Further, list display buttons 54 a and 55 a are displayed beside the WB / BL display field 54 and the mode display field 55, respectively. In addition, a confirmation button 56 is displayed on the lower right side of the print channel setting screen 50.

  Here, a setting method of each item of the print channel on the print channel setting screen 50 will be described. The name, width, and feed can be set by inputting each input field using the keyboard 32. In the scanning mode, when the operator places the cursor of the mouse 33 on the list display button 55a and clicks the right or left button of the mouse 33, the list 55b is displayed. The operator can set the scanning mode by clicking the right or left button of the mouse 33 with the cursor of the mouse 33 positioned on one of the items of the displayed list 55b. At this time, the set mode is displayed in the mode display field 55. WB / BL can be set in the same manner as in the scanning mode.

  The contents set on the print channel setting screen 50 can be confirmed by clicking the right button or the left button of the mouse 33 in a state where the cursor of the mouse 33 is aligned with the confirm button 56.

  In the present embodiment, only when the operator sets a print size (determined by width and feed) that exceeds the reference size on the print channel setting screen 50, as shown in FIG. 4B, the scanning mode list 55b. Is displayed. When the operator sets a print size equal to or smaller than the reference size, the mode display field 55 displays “capability first priority (one time scanning)”. In the present embodiment, the reference size is 89 mm × 127 mm. Note that the scanning mode list 55b may be displayed regardless of the print size selected by the operator.

  Next, three scanning modes of the reading unit 10 of the present embodiment will be described. In the one-time scanning mode, all frames in one film are continuously read at a magnification suitable for creating a reference size print. Thereafter, a thumbnail image is displayed on the display 31 based on the thumbnail image file created by performing a thinning process or the like on the generated image data file. The operator performs a pre-judgment operation to input a correction value, the number of prints, and the like for each frame while confirming the thumbnail image. After the pre-judge operation is completed, the image data file generated by scanning is subjected to correction processing based on the correction value, and the corrected image data file is output to the exposure head 101.

  In the twice scanning mode, first, press scanning is performed to continuously read all frames in one film at a low magnification suitable for displaying a thumbnail image on the display 31, and then a magnification higher than the press scanning is performed. To scan all frames in the film one by one. After the press canning is completed, the display 31 displays thumbnail images based on all the thumbnail image files related to one film generated by the press canning. Then, after the pre-judgment work for all the frame images by the operator is finished, the main scanning is started. When an image for one frame is read, a correction process based on the correction value is performed on the image data file corresponding to the read frame, and the corrected image data file is output to the exposure head 101.

  Note that the size of the thumbnail image file related to each frame generated by reading in the press scanning is sufficiently smaller than the size of the image data file related to each frame generated by reading in the one-time scanning mode. .

  Further, in the main scanning in the quality priority twice scanning mode, the film is read at a magnification suitable for creating a print of the size input by the operator. In the capability priority two-time scanning mode, the film is read at a magnification lower than the magnification suitable for creating the print of the size input by the operator and higher than the magnification suitable for creating the reference size print.

  Returning to FIG. 3, the mode rewriting unit 23 rewrites the scanning mode stored in the mode storage unit 22 to the scanning mode set by the operator on the print channel setting screen 50. The reading control unit 24 controls the reading unit 10 so that the film is read in the scanning mode stored in the mode storage unit 22.

  The reading magnification storage unit 25 stores the reading magnification in the one-time scanning mode and the reading magnification in the main scanning in the two-time scanning mode. The reading magnification storage unit 25 stores a reading magnification when reading a film having a reference width by default. In the present embodiment, the reference width of the film is 35 mm. Further, the reading magnification storage unit 25 stores a magnification higher than the reading magnification of the film in the one-time scanning mode as the reading magnification in the main scanning in the two-time scanning mode. The reading magnification rewriting unit 26 rewrites the reading magnification stored in the reading magnification storage unit 25 based on the film width detected by the width detection sensor 111 and the scanning mode stored in the mode storage unit 22.

  In the one-time scanning mode, the image storage unit 27 stores all image data files related to one film generated by scanning. All the image data files stored in the image storage unit 27 are deleted from the image storage unit 27 after being output to the exposure head 101 for exposure processing. Further, in the case of the twice scanning mode, the image storage unit 27 stores all thumbnail image files relating to one film generated by the press scanning. Further, the image data file generated by reading one frame at a time in this scanning is sequentially stored. The image data file generated by the scanning is sequentially deleted from those related to the frames output to the exposure head 101. Then, after all the image data files generated by this scanning are deleted, the thumbnail image file is deleted.

  The image processing unit 28 stores the image data file generated by the scanning in the one-time scanning mode stored in the image storage unit 27 or the image data file generated by the main scanning in the two-time scanning mode. On the other hand, various correction processes such as a color tone correction based on the correction value input in the pre-judge work are performed.

  Next, a processing procedure in the photo processing apparatus 1 will be described with reference to FIGS. 5 and 6. FIG. 5 is a flowchart showing a film reading procedure in the film scanner 1. FIG. 6 is a flowchart showing the procedure of the interrupt process + performed in the flowchart shown in FIG.

  First, a print channel selection screen 40 as shown in FIG. 4A is displayed on the display 31 (step S101). Then, it is determined whether or not the operator has selected one print channel from a plurality of print channels shown on the print channel selection screen 40 using the mouse 33 (step S102). If it is determined that the print channel is not selected (step S102: NO), the determination in step S102 is repeated until the print channel is selected. On the other hand, if it is determined that a print channel has been selected (step S102: YES), a print channel setting screen 50 for the selected print channel as shown in FIG. Step S103).

  Next, it is determined whether or not the print size set on the print channel setting screen 50 exceeds the reference size (step S104). If it is determined that the print size does not exceed the reference size (step S104: NO), steps S105 to S107 to be described later are omitted, and the process proceeds to step S108. At this time, the mode display field 55 displays “capability priority (one time scanning)” and is set to the one time scanning mode.

  On the other hand, when it is determined that the print size exceeds the reference size (step S104: YES), it is determined whether the operator has displayed the scanning mode list 55b using the mouse 33 (step S105). ). When it is determined that the list 55b is displayed (step S105: YES), the operator uses the mouse 33 to select an item different from the currently set item among the items displayed in the list 55b. Is selected and it is determined whether or not the scanning mode setting has been changed (step S106).

  If it is determined that the scanning mode setting has been changed (step S106: YES), the mode rewriting unit 23 rewrites the scanning mode stored in the mode storage unit 22 to the scanning mode set by the operator. (Step S107). Then, it returns to step S105 and it is judged whether the list | wrist 55b was displayed again. On the other hand, if it is determined that the scanning mode setting has not been changed (step S106: NO), the above-described step S107 is omitted, and the process returns to step S105.

  If it is determined that the list 55b is not displayed (step S105: NO), it is determined whether or not the setting content is confirmed by the confirm button 56 (step S108). If it is determined that the setting content has not been finalized (step S108: NO), the process returns to step S105 to determine whether the list 55b is displayed again. On the other hand, if it is determined that the setting contents have been confirmed (step S108: YES), it is determined whether or not a film has been set in the film mounting unit 110 (step S109).

  If it is determined that no film is set (step S109: NO), the determination in step S109 is repeated until it is determined that a film is set. On the other hand, when it is determined that the film is set (step S109: YES), the width of the set film is detected by the width detection sensor 111 (step S110).

  Subsequently, it is determined whether or not the width of the film loaded on the film loading unit 110 is different from the reference width (step S111). When it is determined that the film width is the reference width (step S111: NO), step S112 described later is omitted, and the process proceeds to step S113. On the other hand, when it is determined that the film is different from the reference width (step S111: YES), the reading magnification stored in the reading magnification storage unit 25 by the reading magnification rewriting unit 26 is the width of the set film, And it is rewritten based on the scanning mode memorize | stored in the mode memory | storage part 22 (step S112). Thereafter, it is determined whether or not the scanning mode stored in the mode storage unit 22 is the one-time scanning mode (step S113).

  If it is determined that the one-time scanning mode is stored (step S113: YES), the reading control unit 24 controls the reading unit 10 so that the film is read in the one-time scanning mode. Specifically, all frames in the film set in the film mounting unit 110 are continuously scanned (step S114). Note that a film to be read next may be set in the film mounting unit 110 immediately after the scanning is completed.

  Then, all image data files relating to one film generated by scanning are written in the image storage unit 27 (step S115). Thereafter, a thumbnail image is displayed on the display 31 based on the thumbnail image file created from the image data file generated by scanning (step S116). At this time, the operator performs a pre-judgment operation for inputting correction values and the like while checking the thumbnail images.

  Next, it is determined whether or not the pre-judgment work has been completed (step S117). If it is determined that the pre-judgment work has not been completed (step S117: NO), the determination in step S117 is repeated until the pre-judge work is completed. When it is determined that the pre-judgment work has been completed (step S117: YES), the image processing unit 28 performs a correction process based on the correction value input in the pre-judge work (step S118).

  Thereafter, the corrected image data file is output to the exposure head 101 (step S119). After all image data files relating to one film are output to the exposure head 101, the image data files stored in the image storage unit 27 are deleted all at once (step S120).

  On the other hand, when it is determined that the scanning mode is not stored in the mode storage unit 22, that is, the scanning mode is stored twice (step S113: NO), the reading control unit 24 scans twice. The reading unit 10 is controlled so that the film is read in the mode. Specifically, first, press canning for continuously reading all frames in the set film at a low magnification is performed (step S121).

  Then, all thumbnail image files relating to one film generated by press canning are written in the image storage unit 27 (step S122). Thereafter, a thumbnail image is displayed on the display 31 based on the thumbnail image file generated by press scanning (step S123). At this time, the operator performs pre-judge work while confirming the thumbnail image.

  Subsequently, it is determined whether or not the pre-judgment work is finished (step S124). If it is determined that the pre-judgment work has not been completed (step S124: NO), the determination in step S124 is repeated until the pre-judge work is completed. If it is determined that the pre-judgment work has been completed (step S124: YES), it is determined whether or not the scanning mode is set to the ability priority two-time scanning mode (step S125).

  If it is determined that the capability priority scanning mode is set (step S125: YES), the reading control unit 24 controls the reading unit 10 so that the scanning is performed in the capability priority scanning mode. Is done. Specifically, a frame of a set film is printed at a magnification lower than a magnification suitable for creating a set size print and higher than a magnification suitable for creating a reference size print. Scanning is performed (step S126). Then, an image data file corresponding to one frame generated by this scanning is written in the image storage unit 27 (step S127). Thereafter, interrupt processing is started (step S128).

  Here, the procedure of the interrupt process will be described. First, as shown in FIG. 6, the image data file corresponding to one frame is subjected to correction processing based on the correction value input in the pre-judge operation by the image processing unit 28 (step S201). Next, an image data file corresponding to one frame subjected to correction processing is output to the exposure head 101 (step S202). Thereafter, the image data file corresponding to one frame output to the exposure head 101 is deleted from the image storage unit 27 (step S203). Note that step S203 is executed sometime until step S134 described later is executed.

  Subsequently, it is determined whether or not the main scanning of all the frames in the film is completed (step S129). If it is determined that the main scanning of all the frames has not been completed (step S129: NO), the process returns to step S126, and the main scanning for the next one frame is performed. On the other hand, when it is determined that the main scanning of all the frames has been completed (step S129: YES), the process proceeds to step S134 described later.

  If it is determined that the capability priority scanning mode is not set, that is, the quality priority scanning mode is set (step S125: NO), the reading control unit 24 uses the quality priority scanning mode. Thus, the reading unit 10 is controlled so that the main scanning is performed. Specifically, the main scanning is performed at a magnification suitable for creating a print of a set size for one frame of the set film (step S130). Then, an image data file corresponding to one frame generated by the scanning is written in the image storage unit 27 (step S131). Thereafter, interrupt processing similar to that in step S128 described above is started (step S132).

  Subsequently, it is determined whether or not the main scanning of all the frames in the film has been completed (step S133). When it is determined that the main scanning of all the frames has not been completed (step S133: NO), the process returns to step S130, and the main scanning for the next one frame is performed. On the other hand, when it is determined that the main scanning of all the frames has been completed (step S133: YES), all thumbnail image files are deleted from the image storage unit 27 (step S134).

  As described above, in the film scanner 1 according to the present embodiment, when the print size is set to exceed the reference size on the print channel setting screen 50, the list 55b in which the scanning mode can be selected is displayed by the list display button 55a. Can be made. Then, the mode rewriting unit 23 rewrites the scanning mode stored in the mode storage unit 22 to the scanning mode selected by the operator from the list 55b. Further, the reading control unit 24 controls the reading unit 10 so that the film is read in the scanning mode stored in the mode storage unit 23. Therefore, the operator can freely select the scanning mode according to the purpose.

  Further, as a scanning mode performed by the film scanner 1 of the present embodiment, one-time scanning is performed in which all frames in one film are continuously read once at a magnification suitable for creating a standard-size print.

  In addition, in the film scanner 1 of the present embodiment, the mode storage unit 22 stores any one of the scanning modes for each print channel. Therefore, a scanning mode can be set in advance for each print channel in accordance with the purpose. Therefore, the workability of the film scanner 1 is improved.

  The preferred embodiment of the present invention has been described above. However, the present invention is not limited to the above-described embodiment, and various design changes can be made as long as they are described in the claims. It is a thing. For example, in the above-described embodiment, the reading magnification storage unit 25 stores the reading magnification in the one-time scanning mode and the reading magnification in the main scanning in the two-time scanning mode, and the reading magnification rewriting unit 26. However, the case where the reading magnification stored in the reading magnification storage unit 25 is rewritten based on the width of the film detected by the width detection sensor 111 and the scanning mode stored in the mode storage unit 22 has been described. This is not a limitation. The operator may input the film width, and the reading magnification rewriting unit 26 may rewrite the reading magnification based on the input information. Further, the reading magnification storage unit 25 and the reading magnification rewriting unit 26 may be omitted.

  In the above-described embodiment, the reading magnification storage unit 25 stores a magnification higher than the reading magnification of the film in the one-time scanning mode as the reading magnification in the main scanning in the two-time scanning mode. As described above, a magnification lower than the reading magnification of the film in the one-time scanning mode may be stored as the reading magnification in the main scanning in the two-time scanning mode.

  Furthermore, in the above-described embodiment, the case has been described in which the scanning mode list 55b is displayed only when the operator sets a print size that exceeds the reference size, and the operator can freely select the scanning mode. This is not a limitation. The operator may freely select the scanning mode regardless of the set print size.

  In addition, in the above-described embodiment, the case where the mode storage unit 22 stores any one of the scanning modes for each print channel has been described. However, the present invention is not limited to this. The scanning mode may not be stored for each print channel.

  In the above-described embodiment, as the twice-scanning mode, the quality-priority twice-scanning mode in which the main scanning is performed at a magnification suitable for creating the set-size print, and the set-size print is created. We explained the case where there is a priority scanning twice mode with the ability to perform this scanning at a magnification lower than the magnification suitable for printing and higher than the magnification suitable for creating the standard size print. Not limited. The two-time scanning mode may not be subdivided into two types, or may be subdivided into three or more types.

  Furthermore, in the above-described embodiment, the case where the mode setting unit 21 sets a single-time scanning mode, which will be described later, as the default scanning mode has been described, but the present invention is not limited to this. The mode setting unit 21 may set the quality priority twice scanning mode and the ability priority twice scanning mode as the default scanning mode. Further, for example, when the print size set by the operator is equal to or smaller than the reference size, the one-time scanning mode may be automatically set, and when the print size exceeds the reference size, the quality priority two-time scanning mode may be automatically set.

  Furthermore, in the above-described embodiment, the case where the film is read at a magnification suitable for creating a reference size print in the one-time scanning mode has been described. However, the reading magnification in the one-time scanning mode is the same as that of the reference size. Any magnification may be used as long as the print can be created. In addition, the scanning magnification in the main scanning in the quality priority two-time scanning mode is not limited to a magnification suitable for creating a print of the size input by the operator, and any magnification that can create a print of the size input by the operator. Good.

  In addition, in the above-described embodiment, the film scanner 1 that reads a film has been described. However, the present invention is not limited to this. The present invention is generally applicable to an image reading apparatus that reads a document on which an image is formed.
