The output size input area 50 is an area for numerically inputting the actual size (inch) of the final output of the output unit 26 such as a printer, and the actual size is indicated by a horizontal size g × a vertical size h. .

The input resolution a is calculated based on the initialization values or the user set values of the output resolution f and the output sizes g and h, and the input resolution display area 47 is calculated.
Is displayed, and the indicator 48 is displayed.

On the other hand, on the control screen 40B in the pixel mode in FIG. 3, a capture pixel size input area 51 is provided as a unique input area. The captured pixel size input area 51 is an area for numerically inputting the number of captured pixels in a set range, and is represented by horizontal pixel number c * vertical pixel number d.

Then, the input resolution a is calculated based on the initialized values or the user set values of the captured pixel sizes c and d, the value is displayed in the input resolution display area 47, and the indicator 48 is displayed. Done.

FIG. 5 is a flowchart of a control program of the image reading apparatus executed by the CPU 21. That is, first, an initialization process is performed (step S
1). In the initialization process, the image reading unit 10 is initialized, and the control screen 40A in the dpi mode shown in FIG. In this case, the parameters, output resolution f and output size g,
The initialization value is set as h, and the input resolution a and the indicator 48 are displayed based on the initialization value.

Next, it is determined whether the end button 45 has been pressed (step S2). When the end button 45 is pressed, the present sequence ends. Exit button 4
If No. 5 has not been pressed, it is next determined whether the pre-scan button 41 has been pressed (step S
3). If the pre-scan button 41 has not been pressed, the process returns to step S2.

When the prescan button 41 is pressed, the image reading section 10 is driven to read a film image and capture it as a prescan image (step S4).
In this case, the image reading unit 10 has a certain fixed resolution,
That is, a film image is read at a resolution that satisfies the condition that the time is short without any problem in display on the entire screen.

Then, the data in the pre-scan image display area 46 is cleared (step S5), and the captured pre-scan image is displayed (step S6). Here, it is determined whether or not the scan button 42 has been pressed (step S7). If the scan button 42 has been pressed, a scan process is performed (step S8), and the process returns to step S2. This scanning process will be described later in detail, but the image reading unit 10 uses the set parameters.
Is a process of reading a film image and taking it into the memory 24.

If the scan button 42 has not been pressed, it is determined whether the dpi button 43 has been pressed (step S9). When the dpi button 43 is pressed, a parameter setting process A for setting output resolution and size parameters is performed on the control screen 40A shown in FIG. 2 (step S10), and based on the set parameters, Input resolution display area 47
And the indicator 48 is displayed (step S11), and the process returns to step S7.

The parameter setting process A in step S10 is performed as shown in FIG.
That is, first, the output resolution f is set to the output unit 26 such as a printer (step S10A). Next, the actual size g, h (inch) of the output to the output unit 26 such as a printer is set (step S10B). In this case, when the size of the A4 sheet or the like is predetermined, the user simply inputs one of g and h, and the other is automatically set. Then, the parameter resolution is calculated based on the parameters f, g, and h thus set (step S10C), and the process returns to the upper sequence. Note that steps S10A and 1
Of course, 0B may be in the reverse order.

Here, the calculation of the parameter resolution in step S10C is based on the image capture size, horizontal Xp, vertical Y
p (inch), output resolution f, output size horizontal g, vertical h
(Inch). That is, Xp and Yp when the trimming operation is not performed are the size of the entire screen of the film mounted on the image reading unit 10. Therefore, the parameter resolution in the horizontal direction is g * f / Xp, and the parameter resolution in the vertical direction is determined by h * f / Yp, and the higher of these horizontal and vertical resolutions is set as the parameter resolution.

On the other hand, in step S9, dpi
If it is determined that the button 43 has not been pressed,
Next, it is determined whether or not the pixel button 44 has been pressed (step S12). When the pixel button 44 is pressed, the control screen 40 shown in FIG.
B is displayed, and a parameter setting process B for setting the number of pixels to be captured is performed (step S13). Based on the set parameters, the input resolution a is displayed in the input resolution display area 47 and the indicator 48 is displayed. (Step S11), and the process returns to Step S7.

Here, the parameter setting processing B in step S13 is performed as shown in FIG. That is, the fetched image sizes (number of pixels) c and d are set (step S13A), and the parameter resolution is calculated based on these (step S13B), and the sequence returns to the upper sequence.

In this case, the parameter resolution is determined based on the image capture size (horizontal Xp, vertical Yp (inch)) and the number of pixels to capture, horizontal c and vertical d. That is, Xp and Yp when the trimming operation is not performed are the size of the entire screen of the film mounted on the image reading unit 10. Therefore, the parameter resolution in the horizontal direction is c / Xp, and the parameter resolution in the vertical direction is obtained by d / Yp, and the higher of these horizontal and vertical resolutions is set as the parameter resolution.

On the other hand, in step S12, pi
If it is determined that the xel button 44 has not been pressed, it is next determined whether or not a trimming operation for designating a region to be cut out on the image has been performed (step S1).
4). When performing a trimming operation, two points P in the prescan image displayed in the prescan image display area 46 are displayed.
A rectangle having a diagonal of 1 and P2 is set as an image reading area (step S15). Since the trimming operation and the setting of the image reading area by the trimming operation are known technologies, the details are omitted here. When the image reading area is set in this way, the process returns to step S7. If this trimming operation is not performed, it means that the entire screen of the prescan image has been selected.

If it is determined in step S14 that the trimming operation has not been performed, it is next determined whether or not the prescan button 41 has been pressed (step S14).
16). If the pre-scan button 41 is pressed, the process returns to step S4, and the pre-scan image is taken again.

If the prescan button 41 has not been pressed, it is determined whether the end button 45 has been pressed (step S17). If the end button 45 has not been pressed, the process returns to step S7. If the end button 45 has been pressed, the present sequence ends.

The scanning process in step S8 is performed as shown in FIG. That is, first, instead of the control screen 40A or 40B, an image capturing screen 60A as shown in FIG.
3 is displayed (step S8A).

Here, the image capture screen 60A is a screen displayed while the scan button 42 is pressed and an image is captured, and the stop (STOP) button 61 is pressed or the designated image is displayed. Displayed until the area is captured. Stop button 61 during import
Other operations are no longer accepted. That is, on the screen 60A, an operable stop button 61, a save (SAVE) button 62, a screen enlargement / return button 6
3. An end button 64 is arranged. Here, the save button 62 is a button for instructing processing related to saving an image, the screen enlargement / return button 63 is a toggle button, and the image capture screen 60A is displayed on the entire display screen of the display unit 23. When the image is enlarged and displayed, the image is restored to the original size by pressing the button. Conversely, when the image is not enlarged to the entire display screen, the image capturing screen 60A is enlarged to the entire display screen by pressing the button. Buttons for performing various instructions. In addition, the end button 64
Is a button for giving an instruction to end the image capturing screen 60A.

A captured image display area 65 for sequentially displaying captured images is provided in a predetermined area of the image capturing screen 60A.
Is completed with the image is the end of the image capture. If the captured image display area 65 and the captured image size do not match, the image display area 65
The displayed portion 65A in which the captured image is displayed almost sequentially while performing predetermined processing, the undisplayed portion 65B to be displayed from now on, and the blank portion 6 in which no image is displayed.
5C.

That is, the size of the captured image and the size of the image display area 65 are confirmed (step S8B), and the magnification for displaying all the captured images is set as the image display size (step S8C). In this case, if the magnification is “1” or more, the value is set to “1”.

Then, a film image of one line is read by a line sensor (not shown) of
4 (step S8D). Here, based on the set magnification, it is determined whether or not the data of the line is display thinning data in the sub-scanning direction (direction in which the line sensor moves) (step S8E). Is not displayed, and the process proceeds to step S8G. If the data is not thinned data, the captured images (captured display images 66) are sequentially displayed in the captured image display area 65 while thinning out the line sensor readout direction according to the set magnification (step S8F). By displaying the whole image in such a manner as to be understood, it is possible to clarify the amount of data read at the same time.

Then, it is determined whether or not the stop button 61 has been pressed (step S8G).
When 1 is pressed, the image capturing screen 60A is terminated, the original control screen 40A or 40B is displayed (step S8H), and the sequence returns to the upper sequence.

If the stop button 61 has not been pressed, it is determined whether or not all the images have been captured (step S8I). If the capture has not been completed, the next line image is captured. Therefore, after the line sensor of the image reading unit 10 is moved to the next line (step S8J), the process returns to step S8D.

When the capture of all the images is completed, the image capture screen 60 as shown in FIG.
B to display all image data 67 (step S8K).

That is, FIG. 8B shows an image capture screen 60B displayed in place of the image capture screen 60A of FIG. 8A when the image capture is completed. In this case, the size of the image capturing screen 60B can be changed by dragging the outer frame of the image capturing screen 60B with the mouse. Also, all image data 6
By dragging the mouse at the portion 7, it is possible to scroll and display the portion that could not be displayed in the captured image display area 65. Note that, in this case, the size of the image capturing screen 60B is set to be not smaller than a predetermined value so as not to lose the operability (eg, the button operation cannot be performed), and the direction in which all the image movements are displayed, that is, the non-displayed portion Do not move in the direction without.

That is, if all the image data 67 has been displayed, it is determined here that the image display has been changed (step S8).
L) If there is no change in the image display, the process proceeds to step S8N described later. If there is a change in the image display, for example, the size of the image capturing screen 60B is changed or the display position of the image in the captured image display area 65 is changed. When a mouse operation or the like for making the change is performed, the size or the image display position of the image capturing screen 60B is changed according to the operation (step S8M).

Then, it is determined whether the save button 62 has been pressed (step S8N). If the save button 62 has been pressed, the image is recorded in the internal storage device 25 as a predetermined file (step S8N). S8
O), and return to step S8L.

If the save button 62 has not been pressed, it is determined whether or not the end button 64 has been pressed (step S8P). If the end button 64 has not been pressed, the process proceeds to step S8L. return,
If pressed, the process proceeds to step S8H, terminates the image capture screen 60B, displays the original control screen 40A or 40B, and returns to the upper sequence.

The following can be considered as a pattern of the displayed portion 65A, the non-displayed portion 65B, and the blank portion 65C in the image display area 65 of the image capturing screen 60A.

That is, FIG. 4B shows a case where the captured image is smaller than the image display area 65, and all data is displayed. In this case, the image is the same even after the capture is completed.

FIG. 4B shows a case where the captured image is larger than the image display area 65 and the aspect ratio of the captured image is larger in the horizontal direction of the aspect ratio of the image display area 65. Size of captured image in horizontal direction and image display area 65
When the magnification is adjusted, a blank portion 65C is generated in the vertical direction.

FIG. 1B shows a case where the captured image is larger than the image display area 65 and the aspect ratio of the captured image is large in the vertical direction of the aspect ratio of the image display area 65. The size of the captured image in the vertical direction and the image display area 65
When the magnification is adjusted, a blank portion 65C is generated in the horizontal direction.

As described above, the captured image is displayed at an appropriate magnification of "1" or less so that the state of the entire image can be understood almost simultaneously with the image capture, so that the captured status can be clearly understood. At the same time, the captured image can be shown to the user.

Further, the relationship between the resolution of the parameter set by the user and the maximum resolution of the image reading device can be clearly understood, and if the resolution of the parameter set by the user exceeds the maximum resolution of the image reading device, Can be warned.

In the above-described embodiment, the warning is given in different colors. However, the warning may be given by sound, or another display form such as flashing may be combined. In addition, other methods may be used for setting the screen, as long as the resolution can be calculated by parameter setting. For example,
The output zoom ratio may be set in addition to the output image size. That is, assuming that the zoom ratio is z, the resolution is z * f in both the horizontal and vertical directions.

Further, the setting of the parameters may be such that a limit value or a set range value is determined, and other parameters cannot be set. Alternatively, a warning may be issued when setting is attempted.

Also, it is difficult to display the captured image if the image capturing screen 60A is too small.
The size of the limit may be set. Or,
Regardless of the image capturing screen, in order to provide an easy-to-view image (it is difficult to see if the image is too small), the image may have a minimum magnification.
