81, 82) or the magnetic head 83 is connected to the electrical contact group 77 by a flexible printed circuit board (not shown). In FIG. 4 shown below, the cartridge film adapter 50 is replaced with a 35 mm that can be attached to the scanner body 1.
The film adapter 30 is shown in an external perspective view. Also,
A slide film carrier 40 for holding a slide film that can be engaged with the film adapter 30,
A strip film carrier 44 for holding a strip film is shown in a perspective view.

35 mm film adapter 3 of this embodiment
Reference numeral 0 has the same outer shape as the groove portion 2 of the scanner body 1 described above, and is formed so that it can be fitted and mounted in the groove portion 2. The side surface of the 35 mm film adapter 30 is provided with a recessed portion 3 that is fitted with a positioning pin (not shown) on the scanner body 1 side when mounted in the groove portion 2 of the scanner body 1.
1 and 32 are provided, and the adapter 30 positions the scanner body 1 in a plane perpendicular to the optical axis by the above fitting.

On the bottom surface of the 35 mm film adapter 30, a leaf spring is urged to form conductive contacts with the terminal groups 28a to 28e provided on the scanner body 1 when the 35mm film adapter 30 is mounted in the groove portion 2 of the scanner body 1. A plurality of electrical contacts 37 are attached.

Therefore, the screen position of the film is adjusted by lens / CCD
The number of drive pulses from the reference position of the holding member 7 is stored in a storage unit (not shown) in the film adapter 30. The stored contents are transmitted to the scanner main body 1 via the terminal groups 28a to 28e, and are used for timing control of start of capturing a film image, timing control for data transfer to a PC as an external device, and the like. . Since the storage means stores information peculiar to the adapter, it is advantageous to provide the storage means inside the film adapter 30. However, a storage means for storing the adapter peculiar information should be provided on the scanner body 1 side. It can also be configured.

Also, this 35 mm film adapter 30
The upper opening is provided with a slit 33 for selectively mounting either the slide film carrier 40 or the strip film carrier 44 as desired by the user. Further, a pin 34 for positioning the carrier is supported by a leaf spring 35 so as to be able to move forward and backward.

The recesses 4 of each of these two types of carriers
Reference numerals 3 and 45 are holes into which the above-mentioned positioning pins 34 are inserted. In the description here, for comparison with the cartridge film adapter 50, the film driving means for moving the film is not particularly provided. The reason is that the film drive itself allows the film adapter 30 itself to be manufactured at a lower cost by manually moving the dedicated film carrier. However, it goes without saying that the film can be automatically fed by adding the film driving means, the film driving amount detecting means and the like in the same manner.

FIG. 5 is a functional block diagram showing an outline of functions of the scanner body 1. When the cartridge film adapter (Fig. 3) is attached to the scanner body 1, the fluorescent lamp 3
A frame of the film is inserted between the lens group 8 and the lens group 8 so as to traverse the optical path. The lens group 8 arranged on the optical path of this optical system is composed of three groups, and an image of a film frame is formed on the linear CCD 9.

The second group 8b of the lens group 8 is moved in the optical axis direction by the focus motor 24 to perform focusing. The optimum focus position for the adapter is stored in advance as one of unique information from the storage means provided in each of the above adapters, and the CPU 23 reads it from this storage means each time focus adjustment is performed. Further, the PI 26 that detects the movement of the focus motor 24 generates a pulse according to the rotation of the focus motor 24,
Output to the connected CPU 23.

Since the focus motor 24 for focusing moves the second group of the lens group 8 to the focus position read from the storage means on the basis of the output of the PI 26, the scanner body. It is possible to omit the autofocus mechanism for focusing in the unit 1. Further, by writing the value adjusted for each adapter in the storage means which is composed of an electrically rewritable nonvolatile memory, the variation error can be eliminated even if there is variation among products. However, the accuracy is further improved.

On the other hand, each of the lens groups 8a to 8c of the lens group 8 is driven by a zooming motor 25 to perform a zooming operation. The PI 27, which detects the movement of the zooming motor 25, generates a pulse signal according to the rotation of the zooming motor 25, and the pulse signal is CP.
Sent to U23. The CPU 23 controls the motor 25 based on the pulse so that the motor 25 has a predetermined focal length.

Further, the CPU 23 controls the scanner body 1
In order to centrally control the entire scanner device including not only the operation of the above, but also the operation of each adapter for the 35 mm film and the cartridge film, it is provided in the scanner main body 1. FIG. 6 is a configuration block diagram showing an outline of the cartridge film adapter 50.

This cartridge film adapter 50
The CPU 101 located in the CPU controls the entire adapter and controls the predetermined data communication with the CPU 23 on the scanner body 1 side. In the storage means 102 connected to the CPU 101, the cartridge film adapter information (for example, focus position), the current state of the cartridge film adapter (for example, the number of film frames, and during feeding / idling / rewinding). The flag indicating inside) and the magnetic data stored in the magnetic medium of the film are stored.

The film 104 pulled out from the film cartridge 103 as shown in the drawing is the spool 1
A magnetic head 83 is in contact with a predetermined position on the film surface. Magnetic data is recorded on the magnetic recording medium on the film 104, and two perforation holes formed at one end of the film are arranged for each frame. When the film is fed, the number of perforation holes is counted. While controlling the film feeding.

At the same time, during the film feeding, the magnetic data written on the film 104 is transferred to the magnetic head 83.
The data is read and reproduced by the magnetic reproduction circuit 107, and after the analog signal amplification process and the digital signal conversion process are performed by the magnetic reproduction circuit 107, the signal data is supplied to the CPU 101. A motor 108, which is a drive source for film feeding, is controlled by a motor control circuit 109 based on a control signal from the CPU 101. The motor 108 is gear-coupled to the film cartridge 103 and the spool 105 via a gear train (not shown).
The film is wound up by driving 08 in the forward direction,
The film is rewound by driving in the reverse direction.

The forced rewind switch (SW) 11
If the user manually turns on 2 as desired,
The CPU 101 instructs the motor control circuit 109 to drive the motor 108 in the reverse direction so as to forcibly rewind the film 104 into the cartridge 103. PR
(Photo reflector: Reflective photo interrupter) 81
And the photosensor control circuit 111 that controls this,
The perforation holes formed in the film 104 are detected, and the detection signal is supplied to the CPU 101.

A data disk, which will be described later, is provided at the bottom of the film cartridge 103, and a predetermined pattern is provided so that the type of film, the exposure sensitivity, the number of shootable images, etc. can be determined (see FIG. 12B). ) Is recorded. And this pattern is PR82 shown in FIG.
Is detected by Next, the operation of the above-mentioned cartridge film adapter will be described with reference to the flowchart of FIG. The cartridge film adapter starts the following processing procedure when mounted on the scanner body.

First, as an initial setting of this adapter, CP
Initialize the RAM in U and each related port (S1)
00). Next, the data required for the initial operation is read from the EEPROM as the storage means (S101). As the data read here, the cartridge film adapter information (focus position data), the state of the cartridge film adapter (for example, the number of film frames, during feeding,
Information about the flag indicating that the rewinding or idling is in progress,
If the previously read magnetic data is stored, the magnetic data is read.

In the first communication (1) with the main body CPU (S102), it is transmitted that the cartridge film adapter 50 is attached to the scanner main body 1, and the data read in step S101 is transmitted. Next, the second communication (2) for receiving various commands from the main body CPU is performed (S103). In step S104, it is determined whether the cartridge film is already loaded in the cartridge film adapter on the basis of the cartridge loading flag read from the storage means. If not loaded, the process proceeds to step S105, while it is loaded. If so, the process branches to step S108. Next, when the cartridge film is not loaded, it is determined whether or not the loading operation of the cartridge film is performed based on the state of the open / close switch of the cartridge lid (not shown) (S105), and the loading operation is performed. If not, the process returns to step S103. On the other hand, if the loading operation of the cartridge film is detected, the process branches to the subsequent step S106.

In step S106, first, the film is idly fed from the film cartridge, and when the first frame is fed, the feeding is stopped. Further, during the feeding operation, the magnetic data corresponding to the first frame is read by the magnetic head. When the idling operation is completed, the magnetic data stored in the EEPROM is initialized and the magnetic data of the first frame is recorded (S107).

Next, in step S108, it is determined whether or not the film is fed. This determination is made in step S
This is performed based on the feeding command from the CPU of the scanner body received at 103, and when a command relating to feeding is received, the process proceeds to step S109, and film feeding described in detail later is executed (S109). On the other hand, when it is determined that the film feeding is not necessary, it is determined whether or not the film is rewound (S110). This determination is made in the same way as in step S108.
When the rewind command is received and when the forced rewind SW is operated, it is determined that rewind is necessary, and the rewind subroutine is executed in step S111. If there is no need, step S above
Return to 103. Here, in the film rewinding routine of step S111, the motor is rotated in the reverse direction, and the motor driving is instructed until the film is completely wound into the cartridge.

Next, the above-mentioned routine "film feeding (S109)" will be described with reference to FIG. When a signal command, for example, "feed the film to the nth frame" is transmitted from the CPU of the scanner main body in step S103 described above, the processing steps of the following procedure are executed.

When the target number of frames and the current number of frames sent from the main body CPU are fetched (S200), the number of target frames and the current number of frames are compared (S201). Branches to step S213, which will be described later, and if they do not match yet, to step S202.
In this step S202, when it is determined that the result of the comparison in the previous step S201 is “the number of target frames> the current number of frames”, the process proceeds to step S203.

In step S203, the motor is instructed to rotate in the reverse direction, and the film is fed back in the film cartridge. Here, when feeding in the rewinding direction, the magnetic data is not read. This is because the magnetic data is read when the frame is wound up and the data is already stored in the EEPROM and is not necessary here.

While the motor is being driven in reverse, it waits until one film of film is fed (S204). When the feeding of one frame is completed, the reverse rotation drive of the motor is stopped (S20
5) Rewinding one frame is completed. When the motor stops, the process returns to step S200 again, and steps S200 to S205 are repeated until the number of target frames is reached.
Next, if it is determined in step S202 that "the number of target frames <current number of frames" is satisfied, the motor is driven in the normal direction to feed the film in the winding direction in step S206. Then, it is determined whether the magnetic data of the frame to be fed has already been read (S20).
7). Here, if the corresponding magnetic data has already been read, the process branches to step S209. On the other hand, the magnetic data is read only when the reading has not been performed yet (S208). In step S209, the process waits until one frame is fed, and when the feeding of one frame is completed, the process branches to the next step S210. In step S210, the motor is stopped to complete the winding of one frame.

Next, it is judged whether or not the magnetic data has been read (S211), and if the magnetic data has not been read, the process directly returns to the beginning step S200 of this routine. On the other hand, when the read is executed,
The process proceeds to the following step S212, the read magnetic data is stored in the EEPROM (S212), and thereafter, similarly, the process returns to the leading step S200 of this routine to repeat the series of processes described above.

As described above, "winding one frame" or "rewinding one frame" is repeated, and when the number of target frames is reached, the process branches from step S201 to step S213 to read the magnetic data of the target frame from the EEPROM (S21).
3). In the next step S214, the magnetic data is transmitted to the CPU of the main body, the film feeding process is terminated, and the process returns to the called routine.

Next, with reference to FIGS. 9A and 9B, the reproduction of the magnetic data performed after the above-mentioned step S206 will be described. FIG. 9A shows the positional relationship between the magnetic head and the magnetic data portion on the film. The magnetic data area 40 is formed in the longitudinal direction of the lower end of the film 104.
2 are formed, and two perforation holes 403 are opened at each upper end of each piece. Also,
An exposed area 404 of the film on which an image is recorded is formed in the center. The detection of these perforation holes is performed based on the output of the illustrated PR (photo reflector) 81. Further, the data written in the magnetic data area is read by the magnetic head 83.

FIG. 9B shows the waveform of the magnetic data reproduced by the magnetic head 83 and the corresponding time series and binarized data. Waveform (i) represents the reproduced waveform signal read from the magnetic data area 402 on the film by the magnetic head 83. The minus side of this signal is detected as the clock (Clk) edge shown in the waveform (ii), and the plus side thereof is similarly detected as the data (Data) edge shown in the waveform (iii).

Then, a time series result of measuring the time from the clock edge to the data edge or the time from the data edge to the clock edge is shown in the diagram (iv). The binary numbers "0" and "1" are determined according to the result of this time measurement, that is, the length of the time from the clock edge to the data edge and the length of the time from the data edge to the clock edge. For example, if the time from the clock edge to the data edge is longer than the time from the data edge to the clock edge (that is, t0> t1), define as "0", and vice versa. You can A diagram (v) shows the result of this binarization process.

Next, the waveforms (i) to (iii) shown in FIG.
FIG. 7 is a time chart regarding the drive of the motor and the output signal of the sensor PR81 at the time of reading magnetic data, and the magnetic data to be read. When the motor is driven in the normal direction (waveform (i)), the presence of the perforation hole 403 is detected based on the output signal of PR81, and the sensor PR8 is detected.
The output of 1 changes from L (Low) to H (High) to L (Low). Here, it is sensed that the magnetic data area starts from the change point where the PR output changes from H to L (waveform (i
i)).

When reading the magnetic data, the film 1
Magnetic data is read by the magnetic head 83 while feeding 04. In this state, the output signal of PR81 is L → H →
When it changes to L, it reaches the position of the next perforation hole, so it is recognized as the end of the magnetic data area at the change point where the PR output changes from L to H. Further, since the film feeding for one frame is completed at the change point where the PR output changes from H to L, the driving of the motor is stopped at this change point and the winding operation is completed. In addition,
The operation of stopping the film feeding is performed in step S2 of FIG.
09, corresponding to S210.

FIG. 11 is a flow chart showing a reproduction processing procedure in the routine "magnetic data read" shown in the above-mentioned step S208. During film feeding, P
When the falling edge of the R output is detected (S41
1) Since the magnetic head has reached the magnetic data area of the film, the generation of the clock edge of the magnetic data is waited for in the standby loop (S412) based on the output of the magnetic head.

When the occurrence of a clock edge is detected, the time from the clock edge to the data edge is measured.
The timer 1 is started (S413). It should be noted that this time counting operation is performed using a timer built in the CPU. Next, it is detected whether or not a data edge has occurred (S414), and if no data edge has been detected, it is detected whether or not the rising edge of PR comes (S415). Here, the rising edge of PR corresponds to the second L → H in the waveform (ii) of FIG. 10 and indicates the end of the magnetic data area. Therefore, when the rising edge of PR is detected, the above series of processing is performed. Upon completion, the routine returns to the called routine (S424). On the other hand, P
If the output of R remains L, the process returns to step S414.

In step S414, when a data edge is detected, the time counting operation of the timer 1 is stopped,
The clocking result from the clock edge to the data edge is stored (S416). Then, the second timer 2 for measuring the time from the data edge to the clock edge is started (S417). This timer 2 is the same as timer 1
A timer built in the CPU is used. Similarly, the clock edge is waited in the standby loop (S418), but if the edge is not detected, it is detected whether or not the PR rises (S419). If the PR rises here, the magnetic data area is detected. Since it means the end of the above, the series of processing is ended as described above, and the called routine is returned to (S42).
4).

When the clock edge is detected in step S418, the time counting operation of the timer 2 is stopped and the time counting result from the data edge to the clock edge is stored (S420). Subsequently, the time measured by the timer 1 stored in step S416, that is, the time from the clock edge to the data edge (timer 1), and the time measured by the timer 2 stored in step S420, that is, the data edge to the clock edge, are stored. The time (timer 2) is compared (S4
21). Here, if timer 1> timer 2, the process proceeds to the next step S 422, and the read magnetic data is determined to be binary data “0”. On the contrary, if timer 1 ≦ timer 2, the process branches to step S423 and the binary data “1”
It is determined that

As described above, the above steps S413-
By repeating S423, the magnetic data reproduction process can be performed. Incidentally, step S415 of this routine
Alternatively, when the rise of the PR is detected in step S419, the process proceeds to step S424 as described above and returns to step S209 of "film feeding" shown in FIG. 8 to wait for the fall of the PR. And this P
When the trailing edge of R is detected, it means that the winding of one frame has been completed. Therefore, the driving of the motor is stopped in step S210, and the film feeding is completed.

Next, the bar code written on the data disk of the film cartridge and its reading mechanism will be described with reference to FIGS. 12 (a) to 12 (c). FIG. 12A shows a bar code formed on the end surface of the film cartridge and a PR (photo reflector) 82 as a mechanism for reading the bar code. In the film cartridge 301, information such as the type of the film is written in the data disk 302 on the end face in the form of a bar code. This data disk 302 is a motor 303
Is operated in synchronization with the rotation of the rotation axis of the film cartridge. The PR 82 optically detects the difference in reflectance of the bar code pattern recorded on the data disc.

FIG. 12B shows an example of the bar code pattern in the data disc. The data disc is composed of a portion with high reflectance (white portion in the figure) and a portion with low reflectance (black portion in the figure), and the binary angle "0" and " 1 ”data is represented, and a small angle is set to“ 0 ”and a large angle is set to“ 1 ”, and the angle ratio is 1: 2.
It has the above ratio.

The white left half shown in the figure is an area for detecting the start and end of the data. When this data disk is rotated counterclockwise as shown by the arrow in the figure, a digital signal as shown in FIG. 12C is obtained as the output of PR. Here, the high reflectivity (white) part of the data disk is L (Low) output, and the low reflectivity (black).
The part is H (High) output. The time width of each of L and H is measured and "0" or "1" of the corresponding data is identified. This data indicates the type of film, that is, whether it is negative film or positive film (hereinafter referred to as negative / positive), black-and-white film or color film (hereinafter referred to as black-and-white / color), exposure sensitivity or The number of shootable images is coded and is decoded according to a predetermined format.

This format is composed of 13 "0" s and "1" s, which are appropriately combined so that there is no continuous pattern in which all are "0" s or "1" s. It is specified that when the pattern data is read out, a pattern having a short width (that is, an angle) and a pattern having a long width appear alternately.

Next, FIG. 13 is a flow chart showing the procedure relating to the above-mentioned data disk read processing. Note that this "data disk read" routine is shown in FIG.
This is executed in the "idle feed" routine shown in step S106. First, an area for storing a timer value described later is initialized (S301). Next, the motor is rotated in the reverse direction, whereby the data disk also rotates counterclockwise (S302). It waits for a period of time after the motor is driven until the rotation is stabilized (S303).

After the waiting time has elapsed, a change in PR output is detected (S304), and if there is a change, a timer is started (S305). The timer for this timing is CP
Use the timer built into U. After the timer is started, it is detected whether the PR has changed again (S306), and if there is a change, the timer is stopped (S307), and the data is sequentially stored in the reserved storage area (S30).
8).

Next, it is determined whether or not the data of the timer value stored in step S308 is the 14th time (S309).
Since the bar code pattern of the data disk is composed of an area that doubles as a start and end and 13 data areas, when the number of detected data reaches 14, the data disk must make one round. become. Therefore, when the number of data is 14th in step S308, the reverse driving of the motor is stopped (S311), and the reading of the information recorded on the data disk is completed. On the other hand, when the number of data is less than 14, the timer is restarted (S310), and the above step S3 is performed.
Return to 06.

By repeatedly executing the steps S306 to S310, it is possible to read the information recorded on the data disk of the film cartridge. Subsequent to the motor stop (S311) described above, a decoding process for converting into "0" and "1" is executed based on the read timer value (S312 to S31).
7). This processing will be described with reference to the example shown in FIG.

First, the read data is (i) in FIG.
Assume that The longest data is searched from the data (S312). This corresponds to the sixth "180" from the left in FIG. 14 (i). In step S313, the longest data is brought to the head. As a result, FIG.
The data string of (i) is shifted to the left by 5 as in the data string of FIG. 14 (ii), and the five data that are initially on the left of "180" are rearranged toward the end.

Next, Max (maximum) and Min of the data
Find (minimum) (S314). The leftmost "180"
Is the data indicating the start and end, so if this work is performed on the 2nd to 14th data, Max is the 4th and 12th "22", and Min is the 11th and 1st.
It is the third "8". For example, an intermediate value between Max and Min is obtained (S315). In this case, an intermediate value between "22" and "8" is calculated and is "15" in this case.

Next, the binary value "0" or "1" is determined using the intermediate value. This is the Max and Mi that we found earlier
The long data is set to "1" and the short data is set to "0" with the intermediate value of n as a boundary (S316). The data obtained as a result is replaced with the data of “0” and “1”, and the data of FIG.
A binary data string as shown in () is obtained. Next, "decryption processing" of the data is performed (S317). This determines, for example, "film type", "exposure sensitivity", and "number of recordable images" in accordance with a predetermined format for the data array obtained up to step S316.

The data (type of film, exposure sensitivity, number of recordable images, etc.) read from the data disk described with reference to FIGS. 12 to 14 is stored in the cartridge film adapter 50 (see FIG. 6 102). Next, FIGS. 15 (a)-(b) and 16
The data optically recorded on the film and the reading mechanism will be described with reference to (a) and (b).

FIG. 15A shows the positional relationship between the optical recording data reading sensor and the optical recording data corresponding to each frame of the film. The lower end of the film 104,
An optical recording data area 410 is formed for each frame below the exposed area 404 where the image image of each frame is recorded. This data 410 is detected by a photo sensor (hereinafter, referred to as SPD) which is an optical recording data reading sensor.
411 does. Based on this data 410, the screen size of the film image taken is determined (details will be described later).
Two perforation holes 403 are formed in each frame at the upper end of the film 104, and the PR 81 detects the perforation holes 403.

Further, FIG. 15B shows the film 104.
The positional relationship of the optical recording data portion formed immediately before reaching the first frame is shown. The lower end of the film 104,
Immediately before the first frame, an optical recording data area 412 different from that shown in FIG. 15A is formed. The SPD 411 also detects this data 412. With this data 412,
The upside-down inversion of the film image taken is determined (details will be described later).

16A to 16V show the SPD 411 which has detected the motor drive, the PR 81 output signal and the optical recording data 410 when reproducing the optical recording data corresponding to each frame of the film. The timing chart regarding an output signal is shown. When the motor is driven in the normal direction (i), PR81 detects the presence of perforation hole 403, and the output of sensor PR81 is L (Low) → H (High).
→ Changes to L (Low) (ii). One frame of film is being fed, that is, PR81 has two perforation holes 40.
While detecting 3, the SPD 411 outputs one of three types of signals “C”, “P”, and “H” according to the optically recorded data 410.

"C" indicates that the output pulse of the SPD 411 is 2
This is the case (iii) where the left and right sides of one frame screen are partially cut off. Also, "P"
Shows the case where one output pulse of the SPD 411 is generated (iv), which represents the screen size in which the upper and lower parts of the one-frame screen are partially cut off. Further, "H" represents the screen size of the single frame screen without the output pulse of the SPD 411 (v). It should be noted that these operations are performed by the routine shown in FIG.
8) ”.

Further, in (i) to (iii) of FIG. 16B, the motor drive during reproduction of the optical recording data formed immediately before reaching the first frame of the film 104, P
7 shows a timing chart regarding the output signal of R81 and the output signal of the SPD 411 that has detected the optical recording data 410. From the state where the film 104 is stored in the cartridge, the motor is driven to rotate in the normal direction, that is, the routine "idle feed" in FIG. 7 (step S10).
6) is started (i), and when the first first frame is detected by the output signal of PR81 (ii), the motor is stopped. If the SPD 411 does not generate a pulse immediately before detecting the first frame, it means that the top-bottom direction of the photographed film image is a normal image. If a pulse is generated, it means that the image is an inverse image (iii).

The optical recording data described with reference to FIG. 15 or 16 is stored in the storage means 102 (FIG. 6) provided in the cartridge film adapter 50. In the above description, data relating to the screen size of the film image and the orientation in the vertical direction is recorded in the optical recording data area of the film and read by the SPD 411. However, these data are recorded in the magnetic data area 40 of the film.
Alternatively, the data may be recorded in No. 2 and read by the magnetic head 83. Even in that case, the read data is stored in the storage unit 102.

Next, the image scanning means will be described with reference to FIGS. 17 and 18. The film image reading operation of the film scanner apparatus according to the present embodiment is divided into main scanning and sub-scanning. FIG. 17 shows a diagram of the linear CCD 9 viewed from the optical axis direction in order to explain the main scanning operation.

The linear CCD 9 has a plurality of pixels 510 arranged continuously in a line. The film image illuminated by the light source means passes through the optical lens and forms an image on the surface of the pixel 510 of the linear CCD 9, and charges corresponding to the amount of light irradiated to each pixel 510 are accumulated. By sequentially measuring the charge amount of each pixel 510 from one end of the linear CCD 9, it is possible to obtain image data for one column. This operation is called main scanning.

Actually, the main scanning range 513 is set depending on the screen size of the film image and the trimming instruction from the operator.
Changes. For convenience, the first pixel of the main scanning range 513 is the main scanning start pixel 511 and the last pixel is the main scanning end pixel 5.
12, the main scanning operation starts from the main scanning start pixel 511 and ends at the main scanning end pixel 512. Also, FIG.
7, main scanning start pixel 511 and main scanning end pixel 51
The scanning order can be changed by controlling the exchange of 2 and 2.

FIG. 18 is a functional block diagram showing the functional outline of the scanner body 1 for explaining the sub-scanning operation. The fluorescent lamp 3, the optical lens 8 and the linear CCD 9 are arranged on the same axis and are integrally fixed to the lens / CCD holding member 7. Here, the linear CCD 9 is fixed with its longitudinal direction aligned with the direction perpendicular to the paper surface in FIG. A screw shaft 15 having a spiral groove with a predetermined pitch is screwed in the lens / CCD holding member 7 in the horizontal direction. Further, the screw shaft 15 is connected to a stepping motor 18 via a gear train (not shown). When the motor 18 is driven to rotate, the lens CC
The D holding device 7 is configured to move in the horizontal direction (that is, the direction perpendicular to the main scanning direction). Further, there is an optical sensor 520 for detecting an initial position as a reference position and an optical sensor 521 for detecting an end position when the lens CCD holding device 7 is horizontally moved.

In the sub-scan, the fluorescent lamp 3 is turned on while the film 104 is not driven, the screw shaft 15 is rotated by the stepping motor 18, and the lens CCD holding device in which the optical lens 8 and the linear CCD 9 are integrally fixed. 7
Is moved in a direction parallel to the film 104.
The position of the lens CCD holding device 7, that is, the absolute position of the sub-scan on the film image can be known by the number of steps of the stepping motor 18 from the position of the optical sensor 520.

Actually, the screen size of the film image,
Sub-scanning range 52 according to a trimming instruction from the operator
4 changes. For convenience, if one end of the sub-scanning range 524 is the sub-scanning start position 522 and the other end is the sub-scanning end position 523, the sub-scanning operation starts from the sub-scanning start position 522, and at the sub-scanning end position 523. finish. Further, in FIG. 18, the sub-scanning start position 522 and the sub-scanning end position 5
It is possible to change the scanning order by performing control so as to replace 23 with.

Since the main scanning direction and the sub scanning direction are orthogonal to each other, the main scanning start pixel 511 and the main scanning end pixel 51.
2, sub-scanning start position 522 and sub-scanning end position 523
Can determine the scan range or scan order of the film image. In the above configuration,
The main scanning is performed while the sub-scanning is performed, and when these are both completed, the reading of the predetermined image data of the film image is completed. The control of these operations is performed by the CPU 23 (FIG. 5).
Do.

Next, the operation of the film scanner device according to the data read from the magnetic data area or the optical recording data area of the film or the data disk of the film cartridge will be described. When a cartridge film is used by the present apparatus, the result obtained by reading the magnetic data of the film described in FIG. 9 or the result obtained by reading the optical recording data of the film described in FIG. When the data related to the screen size of the image is detected, the CPU determines the main scanning start pixel 511 and the main scanning end pixel 5 according to the screen size.
12, sub-scanning start position 522 and sub-scanning end position 523
Is automatically determined. In this way, the scanning range of the film image can be automatically determined according to the read information.

Further, the CPU, depending on the screen size,
It is also possible to automatically determine this magnification by controlling the zooming mechanism of the optical lens 8 without changing the range of main scanning and sub scanning. Furthermore, the CPU can automatically determine the scanning range and the magnification by controlling the zooming mechanism of the optical lens 8 at the same time as determining the range of the main scanning and the sub-scanning according to the screen size.

In this apparatus, the scanning range and the magnification of the zooming mechanism can be arbitrarily changed by the operator's trimming instruction. Even in such a case, the present apparatus stores the data relating to the screen size of the film image in the storage means 102.
Since the CPU reads the data about the screen size from the storage means 102, the CPU scans the scanning range according to the screen size or the magnification of the zooming mechanism of the optical lens 8 according to the screen size. Trimming can be canceled by immediately returning to.

Furthermore, as a result of reading the magnetic data of the film described with reference to FIG. 9, or FIG.
When the data for discriminating upside-down of the film image taken is detected as a result of reading out the optical recording data of the film described in the section 1, the CPU starts the main scanning start pixel in accordance with the upside-down discriminating data. 511 and the main scanning end pixel 512 are replaced with each other to automatically switch the main scanning direction. Thus, by automatically switching the scanning order of the image scanning means on the basis of the data relating to the upside down, the upright image data without upside down can be displayed on the image display means. (Second Embodiment) Next, a second embodiment of the present invention will be described in detail with respect to an image processing method with reference to FIGS. FIG. 19A is a system configuration diagram showing a first means of image processing. Further, FIG. 19B is a system configuration diagram showing a second means of image processing.

FIG. 19A shows a film scanner device of the present invention which converts a film image scanned by the linear CCD 9 into a digital value, performs digital image processing, and transfers the digital image to the PC 538 through the interface port 537. The 1st means of image processing is shown. The A / D converters 530 to 532 are conversion means for converting the image signal obtained by the linear CCD 9 into digital data. Further, the image processing means 533 includes the A / D converters 530-530.
The color balance correction unit 534, the density correction unit 535, and the color inversion unit are processing units that perform digital image processing such as color balance correction, density correction, and negative / positive inversion processing on the digital data converted by 532. 5
It has 36 inside. The storage unit 102 relates to color correction of magnetic data of the film read out by an information reading unit (not shown) (for example, film brand, type of light source at the time of shooting, white balance data, arbitrary input data of the shooter, etc.). Data), optical recording data of film (for example, screen size, vertical direction of screen), data of data disk of film cartridge (for example, type of film, exposure sensitivity, number of recordable images) and the like are stored in advance. The CPU 23 is a control unit that controls the image processing unit 533 based on the data recorded in the storage unit 102. The interface port 537 is a port for transferring the data processed by the image processing unit 533 to the PC 538.

The image signal obtained by the linear CCD 9 is divided into R (red), G (green) and B (blue) color components, and the A / D converter (R) 530 and the A / D converter (G) are divided. 531 and the A / D converter (B) 532 convert into digital data for each color, and the image processing means 5
33 is input. On the other hand, the CPU 23 uses the storage means 10.
The data stored in No. 2 is read, and an instruction based on the data is given to the image processing unit 533.

In accordance with an instruction from the CPU 23, the image processing means 533 uses an internal color balance correction means 534, a density correction means 535, a color inversion means 536, etc. to generate image data for color balance correction, density correction, color inversion, etc., respectively. Performs digital processing. The processed data is
It is transferred to the PC 538 via the interface port 537.

As described above, the image data read by the linear CCD 9 is subjected to the optimum image processing in the film scanner device, and then is sequentially transferred to the PC 538 by following the above-described path in association with the scanning operation. Next, the image processing means 53 based on the data stored in the storage means 102.
Details of operation 3 will be described.

If the storage means 102 has color correction data read out from the magnetic data area of the film, the CPU 23 analyzes the data and analyzes the data.
The color balance correction means 534 in 33 is controlled to automatically adjust the color balance of the image data. Further, when there is data relating to exposure correction such as exposure sensitivity read from the data disk of the film cartridge in the storage means 102, the CPU 23 analyzes it and controls the density correction means 535 in the image processing means 533. Then, the image density of the image data is automatically adjusted.

If there is data in the storage means 102 regarding the type of film, which indicates whether the film is a negative film or a positive film, read from the data disk of the film cartridge, the CPU 23 analyzes it. The color inversion means 536 in the image processing means 533 is controlled to automatically switch the color inversion of the image data. Specifically, if the data is a negative film, the CPU 23 performs the color reversal process, and conversely, if the data is a positive film, the CPU 23 does not perform the color reversal process.

In the above description of the present embodiment, the type of linear CCD is not particularly limited. However, when a so-called three-line type color CCD in which three line CCDs corresponding to R, G, and B colors are arranged in parallel is used as the photoelectric conversion means, the following operation is also possible. That is, if there is data about the type of film indicating whether it is a black-and-white film or a color film read from the data disk of the film cartridge in the storage means 102, the CPU 23 analyzes it and the image processing means. 533 is controlled to automatically switch the resolution of image processing. Specifically, in the case of data indicating that the film is a black-and-white film, the charges output from the three pixels R, G, and B are used as image data of the same portion of the film image to perform image processing. Double resolution can be obtained. On the contrary, if the data indicates that the film is a color film, such processing is not performed.

FIG. 19B shows a second means of image processing in which the present film scanner device does not have an image processing means, and the PC performs the image processing. The above data stored in the storage means 102 and the A / D converter 5
The image data digitally converted by 30 to 532 is once input to the CPU 23 and then transferred to the PC 538 through the interface port 537.

In this configuration, the CPU 23 first reads the film additional information and the film cartridge information stored in the storage means 102, and uses these data in the PC.
538. The PC 538 prepares to process the image data sent subsequently according to the content of this data. After that, the image data is sequentially P-linked in conjunction with the scanning operation.
The data is transferred to the C538, and the PC 538 performs image processing based on the various data previously transferred.

Next, details of the image processing operation in the PC 538 based on the data stored in the storage means 102 will be described. That is, when the storage unit 102 has color correction data read from the magnetic data area of the film, the CPU 23 transfers the color correction data to the PC 538 prior to the transfer of the image data, and the PC 5
38 automatically adjusts the color balance of the image data.

If there is data relating to exposure correction such as exposure sensitivity read from the data disk of the film cartridge in the storage means 102, the CPU 2
3 shows the exposure correction data on the PC before transfer of the image data.
Then, the PC 538 automatically adjusts the image density of the image data. Further, if there is data on the type of film indicating whether the film is a negative film or a positive film read from the data disk of the film cartridge in the storage means 102, the CPU 2
3 transfers the data relating to the type of film to the PC 538 prior to the transfer of the image data, and the PC 538 automatically switches the color inversion of the image data. Specifically, if the data is a negative film, the color inversion process is performed, and conversely, if the data is a positive film, the color inversion process is not performed.

Further, when the storage means 102 has the data regarding the upside-down inversion for discriminating the upside down orientation of the screen read from the optical recording data area of the film, the CPU 23 reverses the upside down orientation before transferring the image data. By transferring the data to the PC 538, an upright image can be automatically obtained by the image display means on the PC 538.

Further, if there is data relating to the type of film indicating whether it is a black-and-white film or a color film read from the data disk of the film cartridge in the storage means 102, prior to the transfer of the CPU23 image data. Data concerning the type of lever film is transferred to the PC 538, and the PC 538 automatically switches the resolution of image processing. Specifically, in the case of data indicating that the film is a black-and-white film, the charges output from the three pixels R, G, and B are used as image data of the same portion of the film image to perform image processing.
Double resolution can be obtained. On the contrary, if the data indicates that the film is a color film, such processing is not performed. (Third Embodiment) In the above description, the scanner body 1
Although the fluorescent lamp 3 is shown as an example of the light source means and the color linear CCD is shown as an example of the photoelectric conversion means, another method may be adopted.

Therefore, a third embodiment of the present invention in which the light source means and the photoelectric conversion means are changed will be described with reference to FIG. FIG. 20 is a functional block diagram showing the functional outline of the scanner body 1 of the film scanner device using the LED as the light source means and the monochrome linear CCD as the photoelectric conversion means. Other configurations are the same as those in FIG.

The LED unit 501 has three L's inside.
It has ED and has R, G and B colors respectively.
Each LED is configured to be able to independently control the amount of emitted light and the timing of lighting, and is controlled by a control signal from the CPU 23. Specifically, the amount of current passed through each LED is adjusted, the duty ratio is adjusted when pulse control is performed, and the amount of restriction is adjusted when an individual restriction is provided before each LED. As a result, the color balance can be adjusted in the light source means. The monochrome linear CCD 502 is a one-line type and converts incident light into an electric signal and outputs it to the CPU 23. Also, CPU
Reference numeral 23 controls the motor 18 so as to scan one film image three times while switching the lighting timing of each LED. Thereby, a color image can be captured.

Next, the operation of the present film scanner device based on the data read from the magnetic data area of the film or the data disk of the film cartridge and stored in the storage means in advance will be described. When a cartridge film is used by this apparatus, the color of the film image is determined by the result of reading the magnetic data of the film described in FIG. 9 or the result of the reading of the data disk of the film cartridge described in FIG. When the data related to the correction is detected, the CPU 23 analyzes the data and controls the LED unit 501 to automatically adjust the light emission amount or the light emission timing of each LED so as to obtain the optimum color balance. In this way, color correction can be automatically performed according to the read information.

When the data concerning the type of film, which indicates whether the film is a black-and-white film or a color film, is detected as a result of reading the data disk of the film cartridge, the CPU 23 analyzes it and analyzes it. 18 is controlled to automatically switch the number of scanning of the film image.
