[2] Relationship between Film Size and Optical System This will be described with reference to FIG. FIG. 1 shows a state in which the optical system of the film scanner device 30 is viewed from the direction of the two-dot chain line arrow a in FIG.

In this optical system, the film 790 and the color CC are used.
D800 is fixed, and illumination unit 55 is used for sub-scanning.
0, first mirror 501, second mirror 502, third mirror 503
Is moved back and forth. Illuminator 550 and first mirror during sub scanning
The 501 and the second mirror 502 and the third mirror 50 are integrated.
3 and 3 are moved integrally by being driven by a stepping motor (not shown). The illumination unit 550 is provided with a halogen lamp for one-dimensional line illumination provided horizontally, and the color CCD 800 is a one-dimensional line sensor having about 5000 pixels of R, G, and B pixels.

In this optical system, films of different sizes are illuminated as described above, and the transmitted light is projected onto the color CCD 800 and read. Therefore, the imaging magnification is changed according to the film size. For example, 35mm film is "x2.51", 6cm film is "x0.95", 4x5inch.
In the film, it is “× 0.57”. Here, the magnification is such that the short side direction of the film is the main scanning direction of the color CCD 800. The film size that is the basis for setting the imaging magnification is as follows:
In some cases, the size corresponding to the size of the trimming area or the size of each divided area of enlarged continuous shooting may be used instead of the size of the film actually mounted on the device 30. The details will be described later.

The change of the image forming magnification is performed by a method of changing the conjugate length. That is, the positions of the second and third mirrors 502 and 503, the position of the imaging lens 520, and the positions of the lens back mirror parts (members mounting the mirrors 504 and mirrors 506) are changed.

For example, in the drawing, the second mirror 502 and the third mirror 503 located at the sub-scanning start position have a solid line of 4 × 5 inc.
In the case of h film, the one-dot chain line shows the case of 6 cm film, and the two-dot chain line shows the case of 35 mm film. The above positioning control is managed by the number of driving steps from a reference position sensor (not shown). Also, the imaging lens 52
0 is at the position indicated by the chain double-dashed line in the 35 mm film and 6 cm film, and in the position indicated by the solid line in the 4 × 5 inch film. The above positioning control is managed by the number of driving steps from a reference position sensor (not shown). Also, the lens back mirror part on which the mirror 504 and the mirror 506 are mounted is in the solid line position for the 6 cm film and the 4 × 5 inch film, and is 35 mm.
It is located at the one-dot chain line in the film. The above positioning control is managed by the number of driving steps from a reference position sensor (not shown).

When the lens back mirror is in the solid line position, the light emitted from the imaging lens 520 (shown by the dotted line in the figure) is reflected by the mirror 504 and then transmitted through the filter block 570 to the primary order. It reaches the original color CCD800. On the other hand, when it is at the position indicated by the alternate long and short dash line, it is reflected by the mirror 504, then by the fixed mirror 505, then by the mirror 506, and then through the filter block 570 to obtain a one-dimensional color. -C
It reaches the CD800.

As described above, in front of the CCD 800, 4
There is a filter block 570 with a variety of filters 571-574 mounted. These filters are
Depending on the positive film, the light quantity to the CCD 800, R, G,
Performs the function of adjusting the B balance. Filter 571
Is, for example, LB100 and is used during actual operation of the negative film. The filter 572 is for loading the negative film shading correction data, and the filter 573 is for loading the positive film shading correction data.
Used respectively. The filter 574 is, for example, an ND filter and is used during the actual operation of the positive film.

The filter block 570 is driven and moved by a stepping motor (not shown). The above-mentioned positioning control is basically managed by the number of driving steps from a reference position sensor (not shown), but a sensor for detecting the upper limit position / lower limit position of the filter block 570 movement range is provided as an auxiliary mechanism. Has been done. In this way, color C
By providing a filter immediately in front of the CD800, there is an advantage that the size of the filter can be minimized. As described above, the reason why different filters are used for the actual operation and the shading operation is that the film does not intervene during the shading operation, and therefore the light amount and the balance are different from those in the actual operation. Is.

It comprises a comparison unit 665 and a clock control unit 661. The image data VD6 is sent from the memory 663 to the pixel clock SYNC.
Are read in synchronization with.

The clock control unit 661 uses the reference clock SCL.
K and magnification data (Mag Da
Based on ta), a clock WCK for writing and a clock RCK for reading are generated.

The write address counter 662 counts the clock WCK for writing with "0" as an initial value at the time of writing and outputs the count value as an address. The read address counter 664 moves data when reading.
Read clock RC with (Mov Data) value as initial value
Counts K and outputs the count value as an address.

At the time of enlargement, as shown in FIG. 9, the cycle of the read clock RCK becomes longer in accordance with the magnification (enlargement magnification), which delays the change of the address value at the time of reading, and the memory 663 stores pixels The same data is read out a plurality of times by the clock SYNC, and expansion processing is performed.
In the example of FIG. 9, it is doubled.

At the time of reduction, as shown in FIG. 10, the cycle of the clock WCK for writing becomes longer in accordance with the magnification (reduction magnification), which delays the change of the address value at the time of writing and causes the image data to be lost. It is thinned out and written in the memory 663. Since the thinned-out image data is read by the pixel clock SYNC, reduction processing is performed. In the example of FIG. 10, the size is reduced to half.

Since the read address output from the read address counter 664 starts from the value of the moving data input thereto, the image moves left and right according to the value of the moving data. The read address counter 664 is
When performing the subtraction operation by RCK, a mirror image of the original image is obtained.

When the repeat data is input, when the count value reaches the value of the repeat data, the comparison unit
A re-count signal (Load) is output from the 665, the movement data is set as the initial value of the read address counter 664, and the counting is restarted from that value. As a result, the address from the value of the move data to the value of the repeat data is repeatedly output, and the data stored at that address is repeatedly read from the memory 663. This operation is performed during reduced continuous shooting.

[4-1] Operation procedure at the time of trimming When the operator wants to trim a film image, the operator displays the film image in the image area 301 and then operates the track ball 351 and the enter key 352. The trimming area is specified by operating and specifying two points in the area.

That is, first, as shown in FIG. 11, the point P1 is designated. This designation is made by moving the cursor to the point P1 and turning on the enter key 352. Next, when the cursor is moved, as shown by the broken line in the figure, the point P1 and the cursor are moved.
A quadrangle trimming frame whose diagonal point is the sol position is displayed. The trimming frame is deformed as the cursor moves, as shown. When the enter key 352 is turned on while the trimming frame matches the area to be trimmed, the inside of the trimming frame at that time is fixed as the trimming area.

When it is desired to change the position of the trimming area after the trimming area is fixed, the enter key 352 is turned on with the cursor displayed in the trimming frame. Then, the trimming frame can be moved, and by operating the track ball 351 in this state, the trimming frame is moved without being deformed in conjunction with the cursor. The operator can appropriately move the trimming frame to change the trimming area to an arbitrary position.

After designating the trimming area in this way,
In order to confirm the trimmed image (trimmed image), the output confirmation switch 309 (FIG. 5) is input to set the output confirmation mode. Then, the input image memory 407 (Fig. 6)
Of the image data stored in, the data of the portion designated as the trimming area is transferred to the VRAM 411 and displayed in the image area 301.

For example, in the case of the normal copy image display, the designated output paper is displayed in white in the image area 301, and the trimming image is arranged and displayed in the center of the paper. If the paper is a standard paper, the trimmed image is automatically scaled and displayed so that the trimmed image is maximized in the paper. Therefore, when the size of the trimming area is changed, the display magnification M is automatically changed. Also, when the paper size is changed, the display magnification M and the size of the trimming image are automatically changed in association with each other. When the output size of the trimming image or the display magnification M is designated, the trimming image is displayed in a size corresponding to that.

[4-2] Display Magnification and Print Magnification In the film scanner device 30, the film image read by the image sensor 800 has a vertical (main scanning direction) of 4096 dots and a horizontal (sub scanning) regardless of the film type. (Scanning direction) 6144 dots of pixels, the aspect ratio is 1 to 1.5
Is. On the other hand, the aspect ratio of standard paper is 1 to 1.41. Therefore, only the portion corresponding to 5792 dots in the horizontal center portion of the film image is printed, and 172 dots in the horizontal direction at both ends are deleted.

The print magnification m, which is the magnification at the time of printout, is used when the pixels of the read film image are printed out without being electrically scaled, that is, one pixel of the film image becomes one dot of the printer. When printed out in correspondence with each other, the actual size is shown. Therefore, for example, when a film image is printed out at the same size with a printer of 400 dpi, an image of about 25 × 36 cm is obtained regardless of the type (size) of film. As described above, the image forming magnification of the optical system is variable according to the film size, and the best image is formed on the CCD 800.
Also, as the film size that is the basis for setting the imaging magnification, in the trimming mode and the magnifying continuous shooting, the size of the trimming area or the size of the trimming area is not the size of the film actually mounted in the apparatus 30. The size of each divided area in the enlarged continuous shooting may be adopted, which will be described later in detail.

On the other hand, the display magnification M is represented by the ratio (dots / mm) of the number of pixels (dots) on the image area 301 to the size (mm) on the paper. That is, as shown in FIG. 12, the pixel configuration of the image area 301 is defined as 297 dots vertically and horizontally.
420 dots, 1 pixel on the screen is 1 mm on the paper
The display magnification M is determined on the basis of the correspondence to. Therefore, when the display magnification M is 1 ×, the image area 30
1 will display 297 mm long and 420 mm wide paper. This is a standard form of A3T (T is arranged in the vertical direction, that is, the longitudinal direction of the paper coincides with the sub-scanning direction. In this case, the longitudinal direction of the paper coincides with the horizontal direction of the screen). This means that the paper is displayed in the image area 301.

Therefore, when the output paper size is A3T, that is, when the display magnification M is the same size, 40
A film image scanned with 96 x 6144 dots is converted to 297 x 42
It will be displayed on the screen with 0 dots. Therefore, when the image data is transferred from the input image memory 407 to the VRAM 411, the image data is reduced to 297/4096.

For vertical papers other than A3T, the display magnification is M = (A3T paper size / selected paper size). For example, when A1T paper is displayed in the image area 301, the display magnification M becomes 1/2.

When the output sheets are arranged in the horizontal direction, the standard size sheet of A4Y (Y indicates that the sheets are arranged in the horizontal direction) is used as a reference. Therefore, when the display magnification M is the same size, the central portion of the image area 301 is 297 vertical dots by 210 horizontal dots.
A4Y standard paper of 297 mm in height and 210 mm in width is displayed on the dots. Display magnification M = (A4Y paper size / selected paper size) for horizontal paper other than A4Y
Becomes

[4-3] Trimming Processing Next, an example of processing of the control unit when trimming is performed will be described. 13 to 15 show the trimming editing screen G.
0 and confirmation screens G1 and G2 are shown. The coordinates in the image area 301 are set to the origin (0,0) at the upper right end position of the image area 301, and “1” per dot is obtained in the downward direction (main scanning direction) and the left direction (sub scanning direction). 1 ”increases by 1.
That is, the coordinates of the lower left position of the image area 301 are (296,419)
become.

As shown in the trimming editing screen G0 of FIG. 13, in the film image FI of A3T size displayed in the image area 301, the trimming frame TF is changed to a dotted line.
It is assumed that the trimming image TI is determined by designating two points P1 (6,133) and a point P2 (212,311). The number of dots on the screen of the trimming image TI at this time is 206 × 178 dots. As the output paper size, A3T standard size paper is specified.

When the output confirmation switch 309 is pressed to enter the output confirmation mode, a confirmation screen G1 as shown in FIG. 14 is displayed. On the confirmation screen G1, the trimmed image TI0 of FIG. 13 is displayed.
Is enlarged by 1.44 (= 297/206) times in both the vertical and horizontal directions, and is displayed as the trimmed image TI1 in the vertical direction of the image area 301, and the trimmed image in the image area 301 is also displayed.
Parts on both sides other than TI1 are displayed as white paper.

The state displayed on the confirmation screen G1 faithfully represents the actual relationship between the paper and the image when the print key 355 is turned on and printed out. Whether or not a desired hard copy image can be obtained can be easily confirmed, and misprinting can be prevented.

When the size of the trimming image TI1 to be printed out is directly specified, the trimming image TI1 of the specified size is displayed in the center of the image area 301 on the confirmation screen G1. In addition, the printing of the state displayed as such is performed.

When it is desired to change the size or position of the trimming image TI1 after the confirmation screen G1 is displayed, the enter trimming mode is turned on by turning on the enter key 352, and the original trimming mode shown in FIG. The image is displayed on the screen, and the trimming frame TF0 can be moved and changed on the screen. After that, the confirmation screen G1 is displayed again as the output confirmation mode, and by repeating these operations, the operator's desired trimming can be easily performed without mistakes.

By the way, as shown in FIG. 13, point P1 (6,133), which is the first two points specified on the screen, and
Point P2 (212,311) is set at point [83 (= 6 × 4096 /) considering that 172 dots in the horizontal direction at both ends are deleted on the film image FI0 at the time of reading from the film. 2
97), 2006 (= 172 + 133 × 4096/297)] and the point [2924 (= 212
X4096 / 297), 4461 (= 172 + 311 x4096 / 297)].
One dot on the screen is 400dpi (about 16 dots / m
In the printer of m), this corresponds to about 16 dots. Therefore, the trimming image TI1 on the confirmation screen G1 shown in FIG.
The two points (0,82) (296,338) correspond to the points (0,1312) (4752,5408) when represented by dots on A3T paper.

Therefore, such a trimmed image TI
In order to print 1 on A3T paper, the scaling moving unit 660 of the image output unit 640 performs the following processing.
That is, the first 1311 lines (one line is one pixel row in the vertical direction of the film image) outputs "white" data, and 13
As the data of the 12th line, the image data of the read film image VD5, the data of 83 to 2924 dots of the 2006 line.
Data is electrically scaled by 1.67 [= 4752 / (2924-83)] times in the vertical direction (main scanning direction) and output.
The data is scaled to 1.67 times in the vertical and horizontal directions (main and sub scanning directions) and output, and "white" data is output from the 5409th line onward.

Further, as shown in FIG. 13, a trimming image
If TI0 is determined and A4Y standard paper is specified as the output paper size, the enlarged trimmed image TI2 is displayed in the image area 30 on the confirmation screen G2 as shown in FIG.
Displayed in the center of the A4Y paper area in 1.

Further, in the present film scanner device 30,
The trimmed image TI0 can be freely moved within the range of the output paper, laid out at an arbitrary position on the paper and printed out, and the layout state can be displayed on the screen.

For example, when the trimmed image TI0 is determined as shown in FIG. 13 and the trimmed image TI0 is to be arranged on the upper right of the output sheet, for example, the output size of the trimmed image TI0 is specified and the output confirmation is performed. Mode
When the cursor is moved to move the trimming frame TF0 to a desired position and the enter key 352 is turned on, the trimmed image is displayed at that position. In this confirmation screen, a window may be provided in an empty area of the operation area (outside of the image area 301) and the position of the enter key 352 when it is turned on may be displayed in the window. If this display is converted into a coordinate position on the output paper and displayed numerically, the position of the trimming image arranged as described above can be accurately known numerically, not by feeling. Therefore, the position of the trimming image can be precisely adjusted, and the occurrence of miscopying can be prevented. In addition,
When displaying the moved image and displaying the cursor position, correction is performed in consideration of the display magnification M.

[5] Example of Setting Position of Inner Frame of Film An explanation will be given with reference to FIGS. 3 and 2. FIG. 3 shows the structure and function of the film carrier of the embodiment [5], and FIG. 2 shows how the scan start position differs depending on the film size.

As described above, the print magnification m is the CCD
One pixel of the film image read by the 800 is printed at the same size as one dot of the printer. The image forming magnification of the film image to be read is set according to the film size. For example, “× 2.51” for 35 mm film, “× 0.95” for 6 cm film, and “× 0.55” for 4 × 5 inch film.
7 ”. Here, the imaging magnification is such that the longitudinal direction of the film is the main scanning direction of the color CCD 800.

Therefore, when it is desired to trim a part of the image area of the film and print it out, the vertical size of the trimming area is the size in the main scanning direction of the color CCD 800 according to the size of the trimming area. If the imaging magnification is set to be approximately the same as
By taking advantage of the resolution of CCD800, the read image with the best image quality can be obtained.

For example, when the desired trimming area in the 4 × 5 inch film is smaller than the size of the 35 mm film, the optical system is set so that the image forming magnification corresponding to the 35 mm film is “× 2.51”, and When the trimming area is set at the scanning position of the 35 mm film and the trimming area is read, the resolution of the color CCD 800 can be used to obtain the image with the best image quality.

In this embodiment, as shown in FIG. 3A, the film carrier FC has a double structure consisting of an inner frame for supporting the film and an outer frame for supporting the inner frame, and ,
By configuring the inner frame to be movable relative to the outer frame, the desired trimming area is set at the scanning position of the 35 mm film.

That is, as shown in FIG. 2, the scan start position is different for 4 × 5 inch film, 6 cm film, and 35 mm film. Therefore, for example, in order to read the trimming desired area in the 4 × 5 inch film shown by the dashed-dotted line rectangle in FIG. 3B with the optical system set for the 35 mm film, the above trimming desired area is 35 mm
It must be located at the scan start position SS for film.

In the present embodiment, this is shown in FIG.
As shown in (c), for the outer frame of the film carrier,
By moving the inner frame of the film carrier shown by the broken line,
Has been realized. It should be noted that the movement is performed manually by the operator here, but a configuration in which the motor is driven may be adopted.

When a film carrier for 4 × 5 inch film is mounted, as described above, this device 30 is used.
Then, an optical system for 4 × 5 inch film is set. Therefore, it is necessary to change this so that the optical system for 35 mm is set. For that purpose, for example, as shown in FIG. 19 of the embodiment [6] described later, an illumination system / optical system for 35 mm is automatically set from the film size and the size of the trimming area. May be.

In the above description, a trimming area of 35 mm film size is provided in the 4 × 5 inch film, but a trimming area of 6 cm film size is provided in the 4 × 5 inch film, and a trimming area of 6 cm film is provided. The same configuration can be applied when a trimming area having a film size of 35 mm is provided in the.

[6] Example of Moving Film Carrier This will be described with reference to FIGS. 16 to 21 and 23 to 30.
16 to 21 show the CPU 400 in the embodiment of the present [6].
3 is a flowchart for explaining the processing in step 1. Also, FIG.
3 to 27 are explanatory views of the movement of the truck and truck board in step S131 of FIG. 17, and FIGS. 28 to 30 are views showing how a large-sized film is divided into small-sized film areas. .

[6-1] Main routine As shown in FIG. 16, in the CPU 400, for example, the processing is started by turning on the power source. First, the RAM 403 is cleared,
Initial system settings such as peripheral device reset
(S11). Next, copy the copy on the CRT display 300.
The initial screen for setting the mode is displayed (S13). Further, shading correction is performed to initialize the CCD 800 (S15). With the above processing, the preparation for reading an image with the film scanner device is completed.

After the above processing, the processing of steps S21 to S37 is executed. When the scan flag is set to 1 (S21: YES), the image reading control is executed (S23).
. The image reading control includes various kinds of processing necessary for reading an image, for example, processing for controlling sub-scanning.
The image reading control will be described with reference to FIG. If the scan flag is reset to 0, (S
21: NO), cursor input processing is executed (S25). In cursor input processing, the cursor moved by the track ball 351
The trimming area is set / moved and the copy mode is set according to the position of the sol and the operation of the enter key 352.

In the film carrier processing (S31), film size detection and the like are performed corresponding to the setting / drawing of the film carrier 700. The film carrier processing will be described with reference to FIGS. Panel key
In the input process (S33), input operations of various keys shown in FIG. 22 are accepted. Further, as shown in FIG. 21, in response to the operation input of the image input key 353 and the print key 355,
The scan flag is set to 1 (S503). In the communication process with the printer (S35), communication with the printer is performed.
For example, the result of the copy mode setting on the CRT display 300, the progress status of the copy, etc. are communicated. AF processing
In (S37), the lens 520 is automatically set to the focal position.

[6-2] Image reading control In FIG. 17, the image reading operation (preliminary scanning, R, G, B
The scanning control of the image is performed until the end of the scanning (S101; NO) (S103). When the image reading operation is completed (S101; YE
S), it is determined whether or not it is the enlarged continuous shooting mode (S111). The enlarged continuous shooting mode is a mode for dividing an image area to be read into a plurality of areas, sequentially reading each divided area, and printing each on a sheet.

If the result of the above determination is that it is not in the enlarged continuous shooting mode (S111; NO), the next image reading operation is unnecessary, so the scan flag is reset to 0 (S113). If it is determined to be the enlarged continuous shooting mode (S111; YE
S), it is determined whether or not the image reading operation for a predetermined number (the set number of enlarged continuous shots) has been completed (S121).
121; YES), since the next image reading operation is unnecessary, the scan flag is reset to 0 (S113).

On the other hand, when the reading of the predetermined number of images in the enlarged continuous shooting mode is not completed, in other words, when the film area to be read in the enlarged continuous shooting mode remains.
(S121; NO), the step motors M1, M2 are driven so that the area is moved to the scanned position (S131). Less than,
The movement of step S131 when enlarging and continuously shooting 4 × 5 inch film onto four sheets will be described with reference to FIGS. 23 to 27.

A 4 × 5 inch film is used as shown in FIG.
When dividing and expanding into two areas (a) to (d),
The size of each divided area is smaller than the size of the 6 cm film. For this reason, after sequentially moving each region to the scanned position of the 6 cm film in the order of (a) to (d), the image reading operation is performed using the illumination system and the optical system for the 6 cm film.

First, as shown in FIG. 24, the motor M1 is driven so that the front end (the right end in the figure) of the area (a) indicated by the hatched portion is the 6 cm film scanning start position, and the area ( The motor M2 is driven so that the vertical center of a) is the vertical center of the 6 cm film. After the movement is completed, the image in the area (a) is read using the illumination system / optical system for the 6 cm film (see S423 in FIG. 20) (S103).

After completion of reading the area (a) (S101; YES, S111; Y
ES, S121; NO), the motor M1 is driven so that the area (b) becomes the scanned position, and as shown in FIG. 25, the area (b) indicated by the shaded area is the scanning start position of the 6 cm film. Is moved up to. Note that the broken line portions in FIGS. 25 to 27 are based on the position of the film carrier FC in FIG.

After the reading of the area (b) is completed, the motor M is moved so that the area (c) becomes the scanned position as shown in FIG.
1, M2 is driven, and similarly, after the reading of area (c) is completed,
The area (d) is moved so that it becomes the scanned position as shown in FIG.
M1 is driven. In this way, when the image reading operation for all areas (a) to (d) is completed (S121; YES), the scan flag is reset to 0 (S113).

[6-3] Film carrier processing In FIG. 18, by checking the sensor state (S201, S2
03), when it is detected that the film carrier FC is pulled out from the truck 750, the carrier set flag is set to 0 (S211), and the screen of the CRT display 300 is cleared (S213). In addition, the film carrier reset process (S21
5) is executed. The contents of the reset can be set in the user setting mode.

Also, by checking the sensor state (S201,
(S203), when it is detected that the film carrier FC is set in the truck 750, the carrier set flag is set to 1 (S221), and the film size is detected (S223). That is, the film size is detected from the type of the film carrier FC as shown in FIG. Further, the film carrier setting process (S225) is executed. In this processing, since the usage status of the output type with respect to the film size differs depending on the usage status of the user, the contents of the default value of the output type can be set in the user setting mode.

On the other hand, by checking the sensor state (S201,
(S203) If the pulling out / setting of the film carrier FC is not detected, it is determined whether the trimming area is set and trimming is designated. As a result, if trimming is specified (S231; YES), the optical system movement process
(S233) is executed. If trimming is not specified (S231; NO), it is determined whether the expanded continuous shooting mode is selected. As a result, if the expanded continuous shooting mode is selected (S241; YES). , Optical system movement processing-2 (S243) is executed.

[6-3-1] Optical System Movement Processing-1 The optical system movement processing-1 shown in FIG. 19 determines the resolution of the sensor based on the film size and the trimming area size when trimming is specified. While setting the illumination system and optical system so that the imaging magnification can be optimally utilized,
This is a process of moving the film (accurately, the truck 750 and truck board 751) to the position to be scanned by the set optical system.

First, the film size is determined (S301,
S303). As a result, if it is 35mm size film,
Since it is the minimum size that can be read by the film scanner device 30, the illumination system / optical system for the 35 mm film is immediately set (S311). Further, the electrical scaling processing described above is performed on the read data (S313).

If the film size is 6 cm, it is judged whether the size of the trimming area is 35 mm or less (S321), and if it is 35 mm or less (S321).
321; YES), the film (accurately, the truck 750 and truck board 751) is moved so that the trimming area becomes the scanned position for the 35 mm film shown in FIG. 2C (S323), and The illumination system and optical system for 35 mm are set (S311). Further, the electrical scaling processing described above is performed on the read data (S313).

If the film is 6 cm in size and the size of the trimming area is larger than 35 mm (S32
1; NO), it is the case that it should be read as a 6 cm film as it is, so an illumination system / optical system for 6 cm is set (S32
5) The above-mentioned electrical scaling processing is applied to the read data (S313).

If the film is a 4 × 5 inch size, it is first determined whether the size of the trimming area is 6 cm or less (S331). If the size is 6 cm or less,
(S331; YES), it is determined whether the size of the film is 35 mm or less (S333).

If the size of the trimming area is 35 mm or less as a result of the above determination (S333; YES), the film is moved to the scanned position for 35 mm (S323), 3 as described above.
The illumination system and the optical system for 5 mm are set (S311), and the subsequent electrical scaling processing (S313) is performed. If the size of the trimming area is larger than 35 mm and smaller than 6 cm (S333; NO), the film is moved to the scanned position for 6 cm (S
335), setting of the illumination system / optical system for 6 cm (S325), and the subsequent electrical scaling processing (S313). If the trimming area size is larger than 6 cm, 4
Since it should be read as a 5 inch film,
Illumination system and optical system for 4x5inch film are set (S33
7) The read data is subjected to the electrical scaling processing described above (S313).

[6-3-2] Optical system movement processing-2 The optical system movement processing-2 shown in FIG. 20 is applied to the film size and the number of enlarged continuous shootings when the enlarged continuous shooting mode is selected. Based on this, it is a process of setting the illumination system and the optical system so that the imaging magnification can optimally utilize the resolving power of the sensor. The process of moving the film (to be precise, the truck 750 and truck board 751) to the scanned position corresponding to the set optical system is executed in step S131 in FIG.

First, the film size is determined (S401,
S403). As a result, if it is 35mm size film,
Since it is the smallest size, the illumination system and optical system for the 35 mm film are immediately set (S411). In addition, the electrical scaling processing described above is performed on the read data (S
413).

The film size is 6 × 4.5, 6 ×
When the size is 6, 6 x 7 cm and the continuous shooting is performed with 6 or more images (S421; YES), each divided area is 35 as shown in FIG.
Since it is smaller than the mm film, an illumination system / optical system for 35 mm is set (S411), and the read data is subjected to the electrical scaling processing described above (S413). If the number of enlarged continuous shots is less than 6 (S421; NO), it means that the film should be read as it is as a 6 cm film. Therefore, an illumination system / optical system for 6 cm is set (S423), and the read data is read. The electrical scaling processing described above is applied to the data (S413).

If the film size is 6 × 9 cm and continuous enlargement of 9 or more images (S431; YES), each divided area is smaller than 35 mm film as shown in FIG. Illumination system and optical system of (S411),
The electrical scaling processing described above is performed on the read data (S413). Also, if the number of enlarged continuous shots is less than 9 (S431; NO), it is necessary to read as a 6 cm film as it is, so an illumination system / optical system for 6 cm is set.
(S423), the electrical scaling processing described above is performed on the read data (S413).

If the film size is 4 × 5 inch, it is first determined whether or not the number of enlarged continuous shots is 20 or more (S441), and if it is less than 20 (S441; NO),
Further, it is determined whether the number of sheets is four or more (S443).

As a result of the above judgment, if the number of enlarged continuous shots is 20 or more (S441; YES), as shown in FIG. 28, since the size of each divided area is smaller than the 35 mm film, the illumination system for 35 mm is used. The optical system is set (S411), and the read data
The electrical scaling processing described above is applied to the data (S413). Further, if the number of enlarged continuous shots is 4 or more and less than 20 (S44
3; YES), since the size of each divided area is larger than the 35 mm film and smaller than the 6 cm film, the illumination system / optical system for 6 cm is set (S423), and the read data is described above. The electrical scaling processing is performed (S413). If the number of enlarged continuous shots is less than 4, 4x5 in
4x5 because it should be read as ch film
The illumination system and optical system for inch are set (S445), and the electrical scaling processing described above is applied to the read data (S41).
3).

In the above-described embodiment, when the size of the trimming area or each divided area in the enlarged continuous shooting mode is smaller than the film of a certain size smaller than the film, the certain size of the certain size is selected. The image reading operation is performed using the illumination system and optical system of the film. On the other hand, in FIG. 30, when the size of the area is larger than a film of a certain size smaller than the film, an image reading operation is performed by using the illumination system / optical system of the film of the certain size. Here is the case. That is, FIG. 30 shows a case where a desired reading area larger than the size of 35 mm is read by six times of image reading operations using the illumination system / optical system for 35 mm.

[0119]

According to the first aspect of the present invention, in the mode (trimming mode) for reading a partial area, an optical system corresponding to the size of the partial area (trimming area) is set. It That is, the optical system is set so that the image of the above-mentioned partial area is formed on the pixels of the maximum number of image sensors. For this reason, the roughness of the enlarged image obtained by electrically processing the image data is reduced as compared with the conventional case.

According to the second aspect of the invention, in the mode of reading different partial areas (enlarged continuous shooting mode), as in the first aspect, the partial areas (divided areas) of the partial area are divided. Since the optical system corresponding to the size is set, the roughness of the enlarged image obtained by electrically processing the image data is reduced as compared with the conventional case.

According to the third aspect of the invention, it is possible to provide an apparatus having a manuscript moving function which can be used in the apparatus of the first and second aspects, with a simple structure of an inner frame body and an outer frame body.
