(Operation and Effect of First Embodiment)
The operation and effect of the embodiment will be described. FIG. 7 is a flowchart illustrating a control procedure performed by the CPU 10 of the scanner main body 1 in the scanning process. FIG. 8 is a flowchart showing a control procedure performed by the CPU 31 of the host computer 4 in the reading condition setting processing.

When a user of the film scanner turns on a power switch (not shown) in FIG.
In, the CPU 10 starts the scanning process. In addition, when the user starts the driver software using the keyboard 32, in S20 of FIG.
31 starts the processing of image reading condition setting. First, the operations from S21 to S25 performed by the CPU 31 will be described with reference to FIG.

In S21, the CPU 31 determines whether or not an instruction to end scanning has been input from the keyboard 32. When the end of the scan is input, the CPU 3
1 performs a process of branching from S21 to S22, and ends the reading condition setting process (S22). On the other hand, if the end of the scan is not input, the CPU 31 proceeds from S21 to S
The process branches to 23.

In S23, the CPU 31 determines whether or not the thumbnail button has been pressed by the keyboard 32. When the thumbnail button is pressed, the CPU
31 starts the thumbnail image reading. When the start of the thumbnail is input, the CPU 31 proceeds from S23 to S
The process branches to 24. On the other hand, when the start of the thumbnail is not input, the CPU 31 holds the state of S23 until the start of the thumbnail is input.

At S24, the CPU 31 transmits a thumbnail command to the CPU 10 via the interface 29. The thumbnail command is a command for causing the film scanner to read a thumbnail image. In addition, CPU
10 and the CPU 31 always transmit and receive signals via the interface 29.
The description of "via the interface 29" regarding the transmission and reception of signals between the CPU 10 and the CPU 31 is omitted.

In S25, the CPU 31
From 0, it is determined whether or not the reception of the thumbnail image data has been completed. When you have received the thumbnail image data,
The CPU 31 performs a process of branching from S25 to S26. On the other hand, when the reception of the thumbnail image data is not completed, the CPU 31 holds the state of S25 until the reception of the thumbnail image data is completed.

Next, referring to FIG.
The control of the PU 10 will be described. In S1, the CP
U10 determines whether or not the strip film adapter 3 is attached based on the output of the adapter detection circuit 17. When the strip film adapter 3 is attached, the CPU 10 performs a process of branching from S1 to S2. On the other hand, when the strip film adapter 3 is not mounted, the CPU 10 holds the state of S1 until the strip film adapter 3 is mounted.

In S2, the CPU 10 performs an initial setting. In this initial setting, the CPU 10 transmits a command to the scan block driving unit driving circuit 26, and drives the scan block 2 by the scan block driving unit 27. The scan block 2 moves to a position where the notch 54a of the aperture 54 is irradiated with the light from the light source 12 by this driving operation. Then, the CPU 10
The illumination driving circuit 11 and the CCD 24 are controlled to measure a shading coefficient and a dark current coefficient. Initial setting is performed based on these measurement results.

In step S 3, the CPU 10 sets the strip film 4 based on the detection signal of the film detection circuit 13.
It is determined whether 0 has been inserted. When the strip film 40 is inserted, the CPU 10 performs a process of branching from S3 to S5. On the other hand, when the strip film 40 is not inserted, the CPU 10 performs a process of branching from S3 to S4.

In S 4, the CPU 10 transmits a control signal to the CPU 31 to display a message indicating that the strip film 40 has not been inserted, for example, “no original” on the monitor 33. Upon receiving this control signal, the CPU 31 sends this message to the monitor 33.
To be displayed. Then, the CPU 10 keeps the state of S3 until the strip film 40 is inserted.

In S5, the CPU controls the roller drive unit drive circuit 18 to drive the roller drive unit 19.
The roller drive unit 19 drives the drive rollers 20a and 20b by a motor and a transmission mechanism. Drive roller 20
The strip film 40 is fed by the rotation of a and 20b, and the length of the strip film 40 is measured by detecting the leading end and the trailing end of the strip film 40 with the CCD 24. Information on the measured length is stored in the memory 28.

At S6, CPU 10 determines whether or not a thumbnail command has been received. Upon receiving the thumbnail command from the CPU 31, the CPU 10 proceeds from S6 to S
Then, the process branches to 7. On the other hand, when the thumbnail command is not received, the CPU 10 keeps the state of S6 until the thumbnail command is received. In S7, the CPU 1
0 performs thumbnail image reading. In this thumbnail image reading, the CPU 10 controls the scan block driving unit drive circuit 26 to control the scan block 2
To move. By this movement, the scan block 2 becomes C
The reading position of the CD 24 is moved to the position where the thumbnail is read, that is, the position where the light from the light source 12 is irradiated to the notch 54a. Then, the CPU 10
Drive rollers 20a, 20b are connected to the roller drive section drive circuit 18.
Is driven to position the leading end of the strip film 40 in the notch 54a. That is, the CPU 10
The drive rollers 20a and 20b are rotated based on the measurement of Step 5.

Next, the CPU 10 performs a thumbnail image reading process. Specifically, the CPU 10 controls the illumination drive circuit 11 to turn on the light source 12. The illuminated light enters the CCD 24 via the strip film 40, the reflection mirror 22, and the projection lens 23. At this time, C
The CD 24 receives light transmitted through the frame 45 and the film information section. Then, the CPU 10 controls the image processing circuit 2
5 to receive the digital signal of the CCD 24. Thereafter, the CPU 10 stores the data in the memory 28. Thus, the CPU 10 obtains a digital signal for one line.

Next, the CPU 10 controls the roller driving unit driving circuit 18 to move the strip film 40 by one line. Then, the CPU 10 obtains a digital signal for the next one line and stores it in the memory 28 in the same manner as described above. The CPU 10 obtains a digital signal line by line up to the end of the strip film 40 based on the length measured in S5 and stores it in the memory 28.

In S8, the CPU 10 transfers the digital signals of all the lines stored in the memory to the CPU 31 as thumbnail image data. In S9,
The CPU 10 determines whether or not the head address of each frame and the LUT for scanning have been received from the CPU 31.
When these addresses and LUT are received, the CPU
10 performs a process of branching from S9 to S10. on the other hand,
If these addresses and LUTs are not received, CP
U10 holds the state of S9 until receiving these.

Returning to FIG. 8, the control of the CPU 31 after the completion of the reception of the thumbnail image data from the CPU 10 will be described. In S26, the CPU 31 recognizes characters in the film information section based on the thumbnail image data by a conventionally known OCR technique. In S27, the CPU 31 determines the maker display 41 by comparing with the dictionary stored in the memory 34. C
The PU 31 can thereby determine the manufacturer name.

In S28, the CPU 31 determines that the memory 3
Only the determined maker among the dictionaries stored in No. 4 is set as a search area. Then, the CPU 31 determines the brand display 42 by comparing the dictionary with the characters. CPU
31 can thereby determine the brand. When there is no brand corresponding to the read character in the search area, the CPU 31 sets the entire dictionary as the search area.
Then, the CPU 31 executes the search again.

Here, the dictionary has character string data of the manufacturer display 41 and character string data of the brand display 42.
In particular, the character string data of the maker display 41 and the brand display 4
It is more accurate to have not only the character string data of No. 2 as a complete character string, but also a part of the character string data of the manufacturer display 41 and a part of the character string data of the brand display 42. The manufacturer display 41 and the brand display 42 can be distinguished. If such a part of the character string is prepared in the dictionary, the manufacturer indication 41 and the brand indication 4 are displayed depending on the leading end and the end of the strip film 40.
Even if 2 is cut off in the middle, the CPU 31 can determine the manufacturer display 41 and the brand display 42.

For example, when the character string data of the maker display 41 is “Nihon”, “Ni”, “Nih”, “Niho”, “iho” which are a part of the character string data of the maker display 41
Prepare string data such as "n" and "hon" in the dictionary. If there is a change in the film manufacturer or brand, the dictionary can be rewritten to respond to changes in the market. The dictionary can be rewritten by a method of rewriting from the keyboard 32 or a method of rewriting a dictionary updated to rewrite the dictionary by using a storage medium such as a floppy disk.

In S29, the CPU 31 determines the memory 3 based on the determined manufacturer display 41 and brand display 42.
Referring to the film database shown in FIG. 4 and stored in FIG. 4, an optimum LUT for the strip film 40 is selected and set. For example, when the maker display 41 is “A” and the brand display 42 is “Z400”, the CPU 31
2 Select and set.

In S27, even if the CPU 31 fails to determine the manufacturer display 41 and an error occurs, if the CPU 31 can determine the brand display 42 in S28, the CPU 31 refers to the film database. Can select L2. On the other hand, in S28, the CPU 31
Even if the determination fails and an error occurs, S27
If the CPU 31 can discriminate the manufacturer display 41, the CPU 31 sets a representative L for each manufacturer.
This LUT can be selected by setting the UT in advance.

Next, in S30, the CPU 31 adds a thumbnail LUT to the transferred thumbnail image data.
Is applied to detect between frames. Since the interval between frames is a film-based density in which an image is not stored, a high level value is obtained in a digital signal sequence of image data, so that it can be detected. Then, the CPU 31
The head address of each frame is calculated from the detected frames.

In S31, the CPU 31 stores the start address of each frame and the LUT set in S29 in the CPU.
Send to 10. In S32, the CPU 31 converts the image into thumbnail image data based on the LUT for the thumbnail and displays the thumbnail image on the monitor 33.
In S33, the CPU 31 determines whether the scan end button on the keyboard 32 has been pressed. When the scan end button is pressed, the CPU 31 performs a process of branching from S33 to S34. On the other hand, if the scan end button is not pressed, the CPU 31 proceeds from S33 to S
The process branches to 36.

In S34, the CPU 31 transmits a scan end command to the CPU 10 via the interface 29, and ends the image reading condition setting process (S3 in FIG. 8).
5). Returning to FIG. 7, in S9, when the CPU 10 receives the top address and LUT of each frame from the CPU 31, the process proceeds to S10.

In S10, the CPU 10 sets the start address of each frame and stores it in the memory 28. S11
, The CPU 10 receives the scan LUT

The process branches from S81 to S83.

In S83, the CPU 62
From 0, it is determined whether the reception of the film information image data is completed. When the reception of the film information image data is completed, the CPU 62 performs a process of branching from S83 to S84. On the other hand, when the film information image data is not received, the CPU 62 holds the state of S83 until the film information image data is received.

In S51 of FIG. 10, the CPU 60
It is determined whether or not the strip film adapter 3 is mounted on the basis of the output of the adapter detection circuit 17. When the strip film adapter 3 is attached,
The CPU 60 performs a process of branching from S51 to S52. On the other hand, when the strip film adapter 3 is not mounted, the CPU 60 holds the state of S51 until the strip film adapter 3 is mounted.

In S52, the CPU 60 performs an initial setting. In this initial setting, the CPU 60 transmits a command to the scan block drive unit drive circuit 26 and drives the scan block 2 by the scan block drive unit 27. The scan block 2 moves to a position where the notch 54a of the aperture 54 is irradiated with the light from the light source 12 by this driving operation. And the CPU 60
