FIG. 5 is a block diagram showing a logical configuration of the scanner 1 that executes the control program in the control unit 130.
The print setting unit 140 displays a print setting menu on the screen 1380 of the display unit 138, and print setting information for specifying the print paper size, print quality, and presence / absence of a border according to the output signal of the operation unit 136. Set. Note that an operation for setting the print paper size and print quality may be accepted without using the screen 1380 of the display unit 138 by pressing a dedicated key for changing the print paper size or a dedicated key for changing the print quality. The print paper size may be set to a standard size such as A3, A4, or L plate, or may be set in units of millimeters or inches.

  The range changing unit 142 changes the reading range. The reading range is a rectangular area that can be set within the prescan range. In addition, as illustrated in FIG. 8, the range changing unit 142 displays the pre-scan image 1384 and the first rectangular frame 1382 corresponding to the reading range on the screen 1380 of the display unit 138 so as to overlap each other. The position and size of the first rectangular frame 1382 with respect to the pre-scan image 1384 are similar to the position and size of the reading range with respect to the pre-scan range. The range changing unit 142 changes the position and size of the reading range according to the output signal of the operation unit 136, and changes the position and size of the first rectangular frame 1382 according to the reading range. The first rectangular frame 1382 corresponds to a “mark indicating an in-screen area” described in the claims. The range changing unit 142 displays the pre-scan image 1384 on the screen 1380 of the display unit 138 together with the first rectangular frame with the same size without being enlarged or reduced. At this time, the prescan image 1384 displayed on the screen 1380 represents an object existing in a predetermined prescan range. A region 1385 indicated by hatching on the screen 1380 is an outer region of the pre-scan image. The “mark indicating the in-screen area” may not be a rectangular frame, but may be, for example, four marks (cross shape, L shape, etc.) indicating the four corners of the in-screen area corresponding to the reading range. A semi-transparent rectangle that matches the in-screen area may be used. In addition, by changing the gradation expression and image quality inside and outside the screen area, such as displaying the screen area in full color and displaying the area outside the screen area in monochrome, the screen area corresponding to the reading range can be changed. May be shown.

  The resolution setting unit 144 sets the resolution of the imaging unit 12 according to the print paper size and print quality set by the print setting unit 140. Specifically, the print resolution is changed according to the print quality, and the resolution of the imaging unit 12 is set according to the size of the scanned image and the size of the read range, which is an integrated value of the print range and the print resolution. The higher the print quality and the wider the print range, the higher the resolution of the imaging unit. Conversely, the lower the print quality and the narrower the print range, the lower the resolution of the imaging unit 12. A scan image can be generated with an appropriate processing amount according to print settings. The resolution setting unit may set the resolution according to only one of the print quality and the print paper size, or set the resolution according to other settings in addition to the print quality and the print paper size. You may do it.

  The prescan image acquisition unit 146 acquires one or more prescan images by causing the imaging unit 12 to read the prescan range determined by the document holder 102. Specifically, when a 35 mm strip film is set on the document holder 102, the prescan image acquisition unit 146 sets the entire exposure target area of the film as a prescan range after detecting the type of the document holder 102, The imaging unit 12 is caused to read the pre-scan range at a relatively low resolution. Next, the prescan image acquisition unit 146 analyzes the image obtained by reading the image pickup unit 12, extracts all the frame areas where the subject is recorded, and sets each extracted image as a prescan image. When a 35 mm mount film is set on the document holder 102, the prescan image acquisition unit 146 detects a plurality of prescan ranges corresponding to a plurality of openings of the document holder 102 after detecting the type of the document holder 102, respectively. The image capturing unit 12 reads the images at a relatively low resolution, and the images obtained by the image capturing unit 12 are used as prescan images.

  The reading range setting unit 148 resets the reading range in accordance with the reading range changed by the range changing unit 142. That is, when the outer area of the pre-scan image is included in the reading range set by the range changing unit 142, the maximum area with the same aspect ratio as that of the print paper size is included in the inner area of the pre-scan image. Reset the rectangular area as the reading range. Even if the aspect ratio of the read area to be reset does not match the aspect ratio of the print paper size, it may be almost the same as the aspect ratio of the print range.For example, the aspect ratio of the print range excluding the left, right, top, and bottom edges Or the aspect ratio of the print range including the margin that protrudes from the printing paper during the four-sided borderless printing.

The scanned image acquisition unit 150 causes the imaging unit 12 to read the reading range set by the reading range setting unit 148 with the resolution set by the resolution setting unit 144, and acquires a scanned image.
The print control unit 152 causes the printer 2 to print the scan image acquired by the scan image acquisition unit 150 under the print conditions set by the print setting unit 140. Specifically, the print control unit 152 generates print data by performing halftone processing, interlace processing, or the like on the scanned image based on the print settings, and sends a print command and print data corresponding to the print settings to the printer 2. The printer 2 outputs the scanned image according to the print setting.
The configuration of the scanner 1 has been described above. Hereinafter, the operation of the scanner 1 will be described.

FIG. 1 is a flowchart showing the operation of the scanner 1 operated by the control program described above. The flowchart shown in FIG. 1 shows the flow of processing when a 35 mm strip film or a 35 mm mount film is set on the document holder 102.
In step S10, the scanner 1 reads the prescan range at a low resolution and generates a prescan image of each frame. Specifically, the control unit 130 functioning as the prescan image acquisition unit 146 and the imaging unit 12 cooperate to generate a prescan image of one or more frames. When generating a pre-scan image, the resolution of the imaging unit 12 is set to, for example, 100 dpi.

  In step S12, the scanner 1 displays a pre-scan image of each frame on the screen and accepts an operation for selecting a frame to be printed. Specifically, for example, the control unit 130 displays the image selection menu shown in FIG. 6 on the screen 1380 of the display unit 138, and the direction instruction keys 1361, 1363, 1365, and 1367 are pressed to output from the operation unit 136. In response to the signal, the control unit 130 sets a frame to be printed.

  In step S14, the scanner 1 accepts a print setting operation for the print target frame. Specifically, the control unit 130 functioning as the print setting unit 140 displays a print setting menu shown in FIG. 7 on the screen 1380 of the display unit 138, for example. In the print setting menu, a paper type, a print paper size, a trimming frame, print quality, and a border process can be selected as setting items using the direction instruction keys 1361, 1363, 1365, and 1367. The paper type is displayed so that photographic paper, plain paper, etc. can be selected. The print paper size is displayed such that A3 Nobi, A3, A4, postcard, L, 2L, etc. can be selected. As the setting of the aspect ratio of the trimming frame, a paper ratio or an arbitrary ratio is displayed so as to be selectable. The print quality is displayed so that high definition or high speed can be selected. As the setting of the border processing, bordered or borderless is displayed so as to be selectable.

  In step S <b> 16, the scanner 1 displays a screen on which the first rectangular frame 1382 corresponding to the reading range and the pre-scanned image 1384 are superimposed on the print target frame. Specifically, the control unit 130 functioning as the range changing unit 142 displays a pre-scan image 1384 of the frame to be printed and a first rectangular frame 1382, for example, as shown in FIG. To display. At this time, the control unit 130 displays the pre-scan image 1384 so that the entire pre-scan image 1384 fits on the screen 1380. The outer region 1385 (hatched region) of the pre-scan image 1384 is displayed in black or the like so that the user can visually recognize the outer edge of the pre-scan image 1384. Further, the size of the reading range is, for example, 70% of the pre-scanning range. When the size of the reading range becomes smaller than the pre-scanning range, the reading range can be moved within the pre-scanning range. As a result, the first rectangular frame 1382 is also displayed on the screen 1380 with a size of 70% of the pre-scan image 1384.

In step S18, the scanner 1 determines whether or not an operation for confirming the position of the reading range has been performed. If the confirmation operation has been performed, the process proceeds to step S24, and if not, the process proceeds to step S20. Specifically, the control unit 130 functioning as the range changing unit 142 determines the presence / absence of the confirmation operation based on whether or not the OK key 1362 is pressed.
In step S20, the scanner 1 determines whether or not an operation for moving the reading range has been received. If the moving operation is received, the process proceeds to step S22, and if not, the process proceeds to step S18. Specifically, the control unit 130 functioning as the range changing unit 142 determines the presence / absence of the moving operation based on whether or not the direction instruction keys 1361, 1363, 1365, and 1367 are pressed.

  In step S22, the scanner 1 moves the reading range. Specifically, the control unit 130 functioning as the range changing unit 142 sets the reading range in accordance with a signal output from the operation unit 136 when the direction instruction keys 1361, 1363, 1365, and 1367 are pressed. For example, as shown in FIG. 9, the first rectangular frame 1382 is translated on the screen 1380 in accordance with the movement of the reading range. Steps S20 and S22 are repeated until an operation for confirming the position of the reading range is performed.

In step S24, the scanner 1 determines whether or not a confirmation operation for the size of the reading range has been performed. If the confirmation operation is performed, the process proceeds to step S30, and if not, the process proceeds to step S26. Specifically, the control unit 130 functioning as the range changing unit 142 determines the presence / absence of a size determining operation based on whether or not the OK key 1362 is pressed.
In step S26, the scanner 1 determines whether an operation for changing the size of the reading range has been accepted. If accepted, the process proceeds to step S28, and if not accepted, the process proceeds to step S24. Specifically, the control unit 130 functioning as the range changing unit 142 determines whether or not there is an operation for changing the size of the reading range depending on whether or not the direction instruction keys 1361, 1363, 1365, and 1367 are pressed. .

  In step S28, the scanner 1 changes the reading range by fixing the position of one vertex of the outer edge of the rectangular reading range and moving the two sides not including the vertex in the normal direction of each side, The first rectangular frame 1382 is deformed according to the change of the reading range. Specifically, for example, as illustrated in FIG. 10, when the right direction instruction key 1361 is pressed, the control unit 130 functioning as the range changing unit 142 responds to the right side of the first rectangular frame 1382 according to the expansion of the reading range. When the left direction key 1363 is pressed, the right side of the first rectangular frame 1382 is moved to the left according to the reduction of the reading range. When the down direction key 1365 is pressed, the lower side of the first rectangular frame 1382 is moved downward according to the expansion of the reading range, and when the up direction key 1367 is pressed, the first rectangular frame 1382 is moved. Move the bottom side upward. The range changing unit 142 also displays an origin mark 1386 on the screen 1380 for clearly indicating the vertex of the outer edge of the reading range that does not move by operating the direction instruction keys 1361, 1363, 1365, 1367 in the upper right corner of the first rectangular frame 1382. It may be displayed. Steps S26 and S28 are repeated until an operation for confirming the size of the reading range is performed.

In step S30, it is determined whether the reading range is within the pre-scanning range. Specifically, the control unit 130 functioning as the range changing unit 142 identifies the boundary of the prescan range, and if the read range is within the prescan range, the process proceeds to step S30, where the read range is outside the prescan range. If so, the process proceeds to step S32.
In step S32, the reading range setting unit 148 resets the reading range. Specifically, the overlapping area of the reading range and the pre-scanning area is calculated, and the centroid coincides with the centroid of the overlapping area with the same aspect ratio as that of the printing paper in the overlapping area, and the rectangular area having the maximum area is determined. Reset as reading range. The reset reading range corresponds to the second reading range described in the claims. At this time, the control unit 130 functioning as the reading range setting unit 148 may display a rectangular frame corresponding to the reset reading range on the screen 1380 as the second rectangular frame 1383.

  In step S34, the image of the area set as the reading range is cut out from the pre-scan image 1384, and the cut-out scan image 1387 is displayed on the screen. Specifically, the control unit 130 functioning as the range changing unit 142 cuts out an image within the reading range of the pre-scan image 1384, and displays the cut-out scanned image 1387 on the screen of the display unit 138 as shown in FIG. Zoom in on the inside. By enlarging and displaying the image in the reading range of the pre-scan image 1384, the user can set the reading range in detail.

  In step S36, the scanner 1 determines whether or not an operation for completely confirming the position and size of the reading range has been performed. If the confirmation operation is performed, the process proceeds to step S38. If not, the process proceeds to step S18. Continue to change the reading range with. Specifically, the control unit 130 functioning as the range changing unit 142 determines the presence / absence of a complete confirmation operation based on whether or not the OK key 1362 is pressed.

  In step S38, the scanner 1 reads the reading range at a resolution corresponding to the printing paper size and printing quality, and generates a scanned image. The resolution setting unit 144 specifies the size of the scanned image according to the reading range, the print quality, and the printing paper size, and sets the resolution according to the size of the scanned image and the reading range. As a result, assuming that the diagonal size of the scan image is X, the diagonal size of the reading range is Y, and the resolution of the imaging unit 12 when generating the pre-scan image is 100 dpi, the resolution when generating the scan image is 100 × X / Y. The scan image acquisition unit 150 causes the imaging unit 12 to read the reading range set by the reading range setting unit 148 with the resolution set by the resolution setting unit 144 and causes the imaging unit 12 to output a scan image.

  In step S40, the scanner 1 causes the printer 2 to print the scanned image according to the print setting. Specifically, the print control unit 152 generates print data by performing halftone processing, interlace processing, and the like on the scanned image, and outputs a print command and print data corresponding to the print setting to the printer 2. As shown in FIG. 12, the printer 2 prints an image on the paper 50 by spraying a scan image with ink on a print range 52 in accordance with a print command and print data. As shown in FIG. 12A, the print range 52 of the “bordered” print is smaller than the paper 50 by the set margin. As shown in FIG. 12B, the print range 52 of “borderless” printing is slightly larger than the paper 50 by the set overprint width.

In step S42, the scanner 1 determines whether an end operation has been performed by the user. If the end operation has not been performed, the process proceeds to step S12 and the above-described processing is repeated.
According to the embodiment of the present invention described above, the scanner 1 can acquire a scan image of an appropriate area according to the printing paper size without waste. That is, since the scanner 1 acquires a scan image that can be printed as it is without being cut out, the scan image acquisition process and the print process are not wasted. Further, according to the scanner 1, since the print scan image is displayed on the screen, the user can predict the print result. Also, if the area specified by the user as the reading range includes an area outside the pre-scan range, the area that does not include the area outside the pre-scan range is automatically reset as the reading area. The reading area can be set without being aware of the outer area. In addition, since the scanner 1 automatically sets the resolution of the imaging unit 12 according to the print paper size, it is possible to speed up the processing from reading to printing while maintaining high print quality. This is because when a relatively small printing paper size is set, the print quality can be maintained high even if the resolution of the imaging unit 12 is set relatively low.

In the above-described embodiment, the form in which the imaging control device described in the claims is provided in the scanner 1 has been described. However, the present invention can also be implemented using a PC that controls the scanner as the imaging control device. That is, the scanner and PC constitute an imaging system, a control program (corresponding to the imaging control program of the present invention) for realizing a copy function is executed by the PC, and the scanner reads the document under the control of the PC. The obtained scanned image may be printed by a printer under the control of the PC. In this case, the mouse, display, keyboard, etc. of the PC correspond to the sheet setting means and the range changing means described in the claims.
In the above-described embodiment, the mode in which the first rectangular frame corresponding to the reading range can be changed has been described. However, the first rectangular frame that cannot be changed may be set according to the print paper size.
