DESCRIPTION OF THE PREFERRED EMBODIMENTS Prior to the detailed description of the embodiments of the present invention, the outline thereof will be described. In the scanner device of the present invention having the configuration shown in FIG. 1, the image signal of the film or the like taken in by the image input means 1 constituted by the line sensor as described above is temporarily stored in the storage means 3, and the encoder -The converter means 5 converts the video signal into a monitor video signal for a television or the like and outputs it. On the other hand, the image signal is image data formed by high resolution R, G, B signals having a number of pixels larger than the number of pixels that can be stored in the storage means 3 via the controller 6, digital RGB for a personal computer or the like. It is a device that can be converted into data and output.

In the present apparatus, since the storage capacity of the storage means 3 is only the capacity for video signals, a relatively small capacity of 200,000 to 400,000 pixels is sufficient.

On the other hand, in this apparatus, the digital RG
When outputting the B data, the image signal input from the line sensor and A / D converted by the controller 6 without using the storage means 3 or by using it as an auxiliary is digital R, G. , B signal and output directly.

The processing of the controller 6 is performed by, for example, a high-speed RISC (REDUCED INSTRUCTIONSET COMPUTER) type microcomputer (hereinafter referred to as RISC type microcomputer). By using the RISC type microcomputer as described above, the controller 6 can be composed of almost only the RISC microcomputer.

The digital RGB data is converted by the controller 6 after the A / D conversion value is directly stored or one line of the line sensor is stored in the storage means 3, and S
Output as a CSI (Small computer system interface) output signal. Of course, because the RISC microcomputer also controls the SCSI output, the expensive SCS
There is no need to use an I controller. In addition, the above R, G,
If the B signal is directly connected to the printer, the captured image data can be directly output to the printer with high resolution.

An embodiment of the present invention having the above features will be described below in detail with reference to the drawings. FIG. 2 is a block diagram of a scanner device showing the first embodiment of the present invention. The control of the entire scanner device of this embodiment is performed by a high-speed RISC microcomputer 11 which is a controller.
Done in. Of course, the controller may be configured with a custom gate array, but if the RISC type microcomputer is used, the number of ICs used can be reduced and the configuration becomes simple. Of course, if there is a RISC microcomputer that includes other constituent blocks in the block diagram of FIG. 2, it goes without saying that the number of constituent blocks can be reduced by incorporating the constituent block portion into the RISC microcomputer. .

Further, in the present apparatus, the line sensor 12 as the image input means is of the R, G, B output type. The output line is composed of a sensor that is separated into three lines of R, G, and B, or one line,
A sensor that outputs R, G, B in order, or consists of two lines, one line of which is dedicated to the G signal,
For the other line, a sensor that alternately outputs the R signal and the B signal (for example, line sensor MN3661A manufactured by Matsushita Electric Industrial Co., Ltd.) is used. No matter which type of line sensor is used, the addresses and timings stored in the image memory 17, which will be described later, are different.

In the scanner device of this embodiment, the image input of the silver salt film will be described below. However, since the image input from the print is technically the same, the image input from the print has the same structure as that of the device. It can be implemented with a thing.

First, a signal flow and a configuration of the present apparatus when the video signal processing for outputting to a home monitor by the present scanner apparatus is performed will be described. The film from which the image data is to be captured is illuminated by the light source unit 23 via the illumination driver 22 based on the instruction from the RISC microcomputer 11. The light source unit 23 includes a fluorescent lamp, a halogen lamp, and an L lamp.
ED etc. can be applied.

The image data for each line of the illuminated film is used as the line sensor 1 constituting the image input means.
R input to the line sensor 12 and output from the line sensor 12
The G and B signals pass through the clamp circuit 13, the sample hold circuit 14, the amplifier 15, and the A / D conversion circuit 16 which is a digital conversion means, are digitally converted, and are stored in the image memory 17 which is a storage means. The data stored in the image memory 17 is a DMA (DIRECT MEMORY ACCESS) circuit 18
Are sequentially read by the latch circuit 19 and are latched by the latch circuit 19 for each pixel, and the D / A conversion circuit 2 as an analog conversion means.
After D / A conversion at 0, it is converted into a video signal by the encoder 21 which is an encoder means and is output.

The video signal can be output in any of the composite signal format and the video monitor R, G and B signal formats. Moreover, since the above-mentioned image memory capacity is used for normal home monitor output, 2
A memory for 0,000 to 400,000 pixels is sufficient.

Further, in the present apparatus, when the image data of the film is taken in by the line sensor 12, it is necessary to feed the film by a predetermined amount every time the unit line is read. The feeding is performed by the film feeding motor (M). The feeding is performed by driving 25 through the motor driver 24 controlled by the RISK type controller 11. A stepping motor is applied to the film feeding motor 25.

When the film is fed, a photo reflector (hereinafter, PR) is passed through the perforation detection circuit 26.
The film feeding motor 25 is continuously rotated while confirming the number of film frames and the position of the film by means of (27) to feed the film. Together with the motor 2
Step 5 is driven.

Magnetic data such as photographing information magnetically recorded on the film is read by the magnetic head 29 and taken into the RISK type microcomputer 11 via the magnetic circuit 28.
Further, when the magnetic data as the recording information is written on the film, it is also written via the magnetic head 29.

The number of frames in the process of taking in the image data, the photographing information read from the film, and the like are displayed on the display unit 30 such as an LCD. Instructions for each operation of the scanner device are given by a group of operation switches (hereinafter, the switches are referred to as SW) 31.

Next, a high-resolution 1 for a personal computer, etc.
A signal flow when outputting an image signal of digital RGB data having a resolution of 1 million pixels or more per screen will be described. Usually, in the above-mentioned device that captures all the image data of 1 million pixels or more into the memory, a very expensive image memory of 1 million pixels or more is required,
It cannot be used as a consumer device due to its cost. Therefore, in the case of the present embodiment, in order to output a signal of high resolution digital RGB data, it is not necessary to use a large-capacity memory of 1 million pixels or more as described above, and the image data captured by the line sensor 12 is processed by RISC. The type microcomputer 11 is configured to convert into digital RGB image data and output.

That is, the R, G, B signals output from the line sensor 12 are input to the RISC type microcomputer 11 via the clamp circuit 13, the sample hold circuit 14, the amplifier 15, and the A / D conversion circuit 16. , Directly, SC
It is converted to a SCSI signal that can be output to SI and output. By performing such processing, the large-capacity memory required for high resolution becomes unnecessary, and the required memory capacity can be reduced to 1/2 or less.

The line sensor 12 performs integral reading for each line, drives the feeding motor 25 by one step,
Drive the film for one line and read the next line. Therefore, one line may be stored in the image memory 17 and then converted into a SCSI signal. When outputting an image signal to a personal computer or the like, there is no need to connect it to a home television monitor, so there is no problem in using the image memory 17 as a SCSI buffer memory.

The output signal of the digital RGB image data is described as SCSI output, but GPIB (GE
NERAL-PURPOSE INTERFACE BUS, IEEE / IEC) and RS-2
32C (RS-232C INTERFACE, EIA / JIS), or
The principle of the data conversion operation is the same for other output signal formats.

FIG. 3 is a perspective view showing the arrangement of the mechanism around the film feeding section of the scanner device of this embodiment. As shown in the figure, the film 45 delivered from the film cassette 41 is wound around a spool 42 and driven by a film feeding motor 25 via a switching drive system 44.

The film 45 has a perforation 45.
As shown in FIG. 3, b and 45c are opened in the front and rear portions above the screen 45a of the film 45. The feeding position of the film 45 is determined by detecting the positions of the perforations 45b and 45c by the change of the reflected light by the PR 27. The PR 27 is a photo interrupter (P) having light emitting and light receiving sensors on both sides of the film 45.
It goes without saying that I) may be substituted.

The light from the light source section 23 passes through the film 45 and the optical system 43 composed of a lens system to form a linear image on the image forming surface of the line sensor 12. If necessary, an optical system or a diffusion plate may be inserted between the light source unit 23 and the film 45. The magnetic head 29 is in contact with the magnetic recording track 45d of the film 45 and reads the photographing data recorded on the track 45d. When rewinding the film 45,
The switching drive system 44 is switched to rotationally drive the cartridge shaft 41a of the cartridge 41 to perform the rewinding.

FIG. 4 is a layout diagram showing the positional relationship between the film, the optical system, and the magnetic head in the film feeding direction. As shown in the figure, the magnetic head 29 is positioned on the cartridge 41 side by about one frame with respect to the reading position on the film 45 of the line sensor 12. In addition, the PR 27, which is a perforation detection unit, includes the line sensor 12
Other perforation positions may be detected as long as the reading start position can be limited.

The reason why the above positional relationship in the feeding direction is adopted is that when the image is read by the line sensor 12, it is inevitably a low speed and a step operation, so a certain speed and a constant speed are required. Magnetic reading becomes difficult. Therefore, with the above positional relationship, when the film 45 reaches the reading start position of the line sensor 12, the magnetic reading of the corresponding frame can be already finished. Therefore, the line sensor 12
The film 45 can be moved continuously at high speed up to the reading start position, and the magnetic data of the frame read by the line sensor 12 can be magnetically read before the line sensor 12 reads.

In the scanner device of the present embodiment, according to the output format of the image data, for example, whether to output a home video signal or a high resolution digital RGB image data signal, In order to adjust the read state of the image data on the film, the optical system 43 is moved to adjust the focus state on the line sensor 45. That is, the state of the positional relationship shown in FIG. 4 indicates the positional relationship when high resolution reading is performed and digital RGB data (output signal for personal computer) is output, and the optical system 43 with respect to the line sensor 12. It shows a state in which it is positioned at the RGB position 43A which is in perfect focus.

FIG. 5 is a diagram showing a positional relationship when a video signal is output, in which the optical system 43 is just in focus RGB.
It is slightly displaced from the position 43A and is located at the video position 43B. By shifting the focus in this way, no trouble occurs even when the line sensor 12 is read at a high speed at a relatively coarse pitch of the film 45. It is of course possible to skip-read the line sensor 12 in the just-focused state shown in FIG. 4, and the image becomes a little stepped, but if this is within the allowable range, The skip reading for video signal output may be performed in the state of FIG.

Further, FIG. 6 shows a modification in which the line sensor 12 is moved and the focus is shifted while the optical system 43 is fixed when the video signal is output. As a method of moving the optical system 43 and the line sensor 12 as described above, a motor may be automatically used. Of course, it may be mechanically driven at the time of switching between the video signal output and the personal computer digital RGB data output.

FIG. 7 is a perspective view of the apparatus body showing the panel surface of the scanner apparatus of this embodiment. As shown in the figure, the cassette insertion opening 51a arranged on the left side of the main body panel surface
Is an insertion opening of the film cassette 41, and a lid 51
b is attached. Further, the LCD as the display unit 30
The display unit 52 displays the contents described later. The frame return SW52 as the operation SW31 is a switch for instructing one frame rewind, and the frame advance SW53 is a switch for instructing one frame advance. The ten-key SW54 from 1 to 0 can be pressed by continuously pressing this switch.
This is a switch that sets the target number of frames.

When the target number of frames is set, the film is automatically fed to the target frame. Needless to say, it is also possible to hold down the frame return SW 52 or the frame advance SW 53 to count down or count up to substitute for the ten-key SW 54 for setting the target frame.

The negative / positive SW 55 is a switch for selecting whether to output the input image negatively or positively. Further, the video / RGB switching SW 56 is set to a mode in which when the switch is switched to the video side, the image data is input from the line sensor at a relatively high speed and the data stored in the image memory is output as a video, and is switched to the RGB side. And a switch that is set to a mode for inputting image data of high resolution at a relatively low speed and outputting digital RGB data by SCSI. The power SW 57 is a power switch of the scanner device.

FIG. 8 is a view showing a display example of the LCD display section 52. The cassette mark 52a shown in this figure is
Blinks when cassette 41 is not inserted and cassette 41
Prompt the insertion of. The number of frames 52b indicates the current number of frames.
The "target" display 52 is displayed when the target frame is set, and at that time, the target frame number is displayed in the frame number 52b. When the film 45 is fed and driven toward the target, the number of frames becomes 5
2b changes to the current number of frames, and the number of frames changes toward the target.

The "video / RGB" display 52d displays "video" in the video output mode and "RGB" in the personal computer digital RGB data output mode. The "negative / positive" display 52e displays "negative" in the negative output mode and "positive" in the positive output mode.

Image processing of the scanner device of the present embodiment configured as described above will be described below with reference to the flowchart of FIG. 9 and the like. FIG. 9 shows the scanner device according to the RI.
It is a main flowchart in the case of being configured by an SC microcomputer, and the processing of this figure is started when the power SW 57 is turned on.

That is, when the power SW 57 is turned on, initialization is first performed (step S100). Next, it is checked whether or not the film cassette 41 is inserted (step S
101). This check may be performed by interlocking a switch with the operation of the lid 51b of the cassette insertion port 51a, or may directly detect that the cassette 41 has been inserted.

If the film cassette 41 is not inserted, the power SW 57 is checked (step S10).
2) When turned off, this process ends. Power switch
If 57 is turned on, the cassette insertion display, that is, the cassette mark blinks, and the process waits until a cassette is inserted (step S103). When the cassette 41 is inserted,
The "film loading process" of the subroutine for loading the film 45 up to the first frame is executed (step S104). Next, the current state is displayed on the LCD display unit 52 (step S105).

Next, the frame feed SW 53 is checked (step S106), and if the feed SW 53 is turned on, the target frame count OK is substituted with the current frame count K plus 1 (step S114). , "OK frame advance processing" of a subroutine described later is executed (step S11).
6).

Next, the frame return SW 52 is checked (step S107), and if it is on, the current frame number K-1 is substituted for the target frame number OK (step S115), and the "OK frame feed process" of the subroutine is executed. Is executed (step S116). ◎ Next, it is checked whether the target frame number OK is set (step S108), and if it is set,
The "OK frame advance process" of the subroutine is executed (step S116). If it is not set, the process proceeds to step S109 and later described below. After the OK frame advancing process, it is checked whether it is the video output mode or the digital RGB output mode (step S117), and if it is the video output mode, the "video 1 frame advancing process" of the subroutine described later is performed to output the video signal. Output (step S11
8). If it is the RGB processing mode, the process jumps to step S119 without performing any processing.

In the step S109, the rewinding SW
If the rewind switch is pressed, the film is rewound (step S113), and the process returns to step S101. If the rewind switch is not pressed, the process proceeds to the next step S110, and it is checked whether the video output mode or the RGB mode is selected (step S1).
10). If it is the video output mode, the process jumps to step S119 described later, and if it is the digital RGB output mode, the process proceeds to step S111.

In step S111, the presence / absence of an image input instruction is checked. If there is no image input instruction, the process proceeds to step S119.
The image data is output to high resolution by SCSI by "RGB processing" of a subroutine described later (step S11).
2). The image input instruction is normally given by SCSI from the host microcomputer, but other methods may be used.

In step S119, the negative / positive SW is set.
55 is determined, and each reading mode is set (steps S120 and 121). And power SW5
The state of No. 7 is checked (step S122). If it is on, the above loop is repeated, and if it is off, this process is terminated.

Next, the "film loading process" of the above subroutine will be described with reference to the flowchart of FIG. First, the initial operation is performed and the film can be fed (step S201). Next, the magnetic circuit 2
8 is turned on so that the magnetic data of the film 45 can be read (step S202).

Further, a motor (stepping motor) 25
Is continuously rotated and waits until perforation can be detected (step S204). When the perforation is detected, the film 45 has been fed to the position of the first frame, the motor 25 is stopped, and the magnetic circuit 28 is turned off (steps S205 and S206). The read magnetic data is stored in the RAM in the RISC microcomputer 11.

In the above state, the first frame has been reached,
1 is substituted for the number of frames K (step S207), the mode is checked (step S208), and in the case of the video output mode, the "video one frame advance process" of the subroutine described later is executed (step S209), and the digital output is performed. RG
In the B mode, this subroutine is finished as it is.

FIG. 11 shows an example of a screen output in the video output mode. In the example of this figure, the number of frames and the date read from the magnetic data together with the image data are superimposed on the screen 61. The magnetic data may or may not be displayed. If the shutter speed, aperture value, etc. are recorded in the magnetic data, that data may also be displayed. In any case, whether or not to superimpose on the screen 61 is a design problem.
This can be easily realized by overwriting the data in No. 7. In the case of the digital RGB mode, the personal computer can take in the above magnetic data from SCSI as a matter of course.

Next, the "OK (target frame) frame advancing process" of the above subroutine will be described with reference to the flowchart of FIG. First, the target frame number OK is compared with the current frame number K (step S301), and the target frame number OK>
If the number of frames is K, that is, if the target number of frames OK is larger than the current number of frames K, the process proceeds to step S302, and if not, the process jumps to step S321 described later.

At the step S302, the target number of frames O
It is determined whether or not K = the number of frames K−1, and if they are not equal, the motor (stepping motor) 25 is normally rotated by continuous rotation (step S303). If they are equal, the process jumps to step S308 described below. By the forward rotation of the motor, the frame advances by one frame (step S304).
In this case, the number of frames is incremented by K ← K + 1 and the number of frames is displayed (steps S305 and 306). Here, the number of frames on the LCD display unit 52 is counted up. Subsequently, the target frame number OK = the frame number K-1 is determined (step S307), and the above process is repeated until OK = K-1.

When the target number of frames OK = the number of frames K-1 is reached, the process proceeds to step S308, and the magnetic circuit 28 is turned on to read the magnetic data of the target frame because it has reached to the position just before the target frame. Prepare. Next, the motor is rotated in the forward direction, the motor is stopped after advancing one frame, and the magnetic circuit is turned off (steps S309, 310, 311, 31).
2). The magnetic data of the target frame number OK is stored in the RAM of the RISC type microcomputer 11 by the processing so far.

Next, the number of frames K ← K + 1 is performed and displayed (steps S313 and 314). This means that the film has been fed to the image reading preparation position of the target number of frames.

Next, the mode is checked (step S315), and if it is the RGB mode, this routine is terminated. Then, the image input instruction waiting state is entered. In the video output mode, the subroutine "video one frame advance" is performed, the video signal is output, and the process returns.

In the determination of the first step S301,
If it is determined that the target frame number OK> the frame number K is not satisfied, the process jumps to step S321, where the motor is rotated in the reverse direction. Then, when one frame is returned, the frame number K is decremented by one by the frame number K ← K-1 (steps S322 and 323). Where OK = K-1
If not, the display is performed and the process is repeated until OK = K-1 (steps S324 and 326).

The reason for rewinding to the target number of frames OK = the number of frames K−1 is that it is necessary to read the magnetic data. If the magnetic data is not read, the target number O
It is sufficient to return K to the number of frames K. In such a case, it is sufficient to jump to step S314 after stopping the motor.

Next, after the target frame number OK = frame number K-1 is rewound, the motor is stopped (step S32).
5) Perform the same processing as when the motor rotates forward. Where OK =
When K-1 is displayed, no display is made, so that the user does not feel uneasy. The target frame number OK is not counted down on the display. Although the frame number K ← K + 1 is performed in the process of step S313, when the target frame number OK = the frame number K−1 was originally not displayed, the display does not change after the target frame number is reached.

Next, the "video one frame advance process" of the above subroutine will be described with reference to the flowchart of FIG. First, as described in FIG. 5, the optical system 43 is moved to the video position 43B that is not the just focus position (step S401). Next, the illumination by the light source unit 23 is turned on, and the line sensor 12 is integrated (step S4).
02, 403). The integration time of the line sensor 12 is constant during image input for one frame.

When the integration is completed, the image data is sampled every nth, and is read out at high speed without outputting all the sensors (step S404). Next, the motor (stepping motor) 25 is advanced by n steps (step S405). Here, it is assumed that the sensor pitch and the pitch at which the film is moved by the stepping motor are the same.

It is checked whether the above processing is completed for one frame (step S406), and if the image for one frame is input, the illumination by the light source unit 23 is turned off (step S40).
7). Here, although not shown in the flow, the input image stored in the image input by the DMA 18 is output as a video signal. At this time, output is performed according to the negative / positive mode.

Next, the motor 25 is driven to return the film by one frame to return the film frame to the frame display position, and the motor 25 is stopped (steps S408, 409,
410), the processing of this subroutine ends. Therefore,
Frame display and film position will always be consistent.

Next, the "RGB processing" of the above subroutine will be described with reference to the flowchart of FIG. The process of steps S501 to 511 of this figure is different from the "video one frame advance process" of FIG. 13 in that the optical system 43 is set to the RGB position 43A (step S501) to bring it into a just focus state, and all the line sensors 12 are used. The motor (stepping motor) 25 is also driven step by step so that the image data of can be read (step S506),
The difference is that the image data with the highest resolution is output to SCSI (step S505).

This RGB processing takes a little time, but since SCSI output is performed line by line, high resolution image data can be output with a small buffer memory. The negative / positive data conversion can also be handled as a series of processes.

Next, a scanner device showing the second embodiment of the present invention will be described. As shown in the block diagram of FIG. 15, the scanner apparatus of the present embodiment has the SC of the RISC type microcomputer 11 in the configuration of FIG. 2 showing the apparatus of the first embodiment.
This is an embodiment of a printer device with a built-in printer in which the SI output unit is directly connected to the printer 71.

FIG. 16 is a perspective view of the scanner device of this embodiment as seen from the panel surface side. The difference from the panel surface in FIG. 7 is that the apparatus main body 81 does not include the video / RGB switching SW 56, the print SW 82 is provided, and the print discharge port 83 is provided. Further, this scanner device has a video signal output terminal, and an image can be confirmed on the home monitor 85 before printing. The same members arranged on the panel surface in FIG. 7 are designated by the same reference numerals in FIG. 16.

FIG. 17 is a main flowchart of image processing of the scanner device of this embodiment. The difference from the flowchart of FIG. 9 is that, in the case of the present embodiment, it is necessary to always perform monitor output and image confirmation, so that the determination of the instruction by the video / RGB switching SW in steps S110 and 117 is eliminated. Instead of determining the image input instruction in step S111, the print SW in step S111A
82 has subscribed to determine if it is on. The subroutines called in steps S104, S116, and S112 are partially different. Other steps are shown in FIG.
