Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to an information reproducing apparatus and an image reading apparatus for reading and writing magnetic information of an undeveloped long film or optically burning the information.

[0002]

2. Description of the Related Art An image reading apparatus for reading a film image photographed by a camera is known as a film scanner (for example, Japanese Patent Application Laid-Open No. 3-145881). The film scanner receives a read command from the host computer, reads an image on a negative film or a reversal film, and outputs the image to the host computer.

In recent years, a new standard film system has been proposed. This new film system handles long films (hereinafter referred to as "roll films") stored in cartridges. That is, the user handles the cartridge without touching the roll film, and receives the cartridge containing the developed roll film even after the development.

[0004] For this reason, the 35 m
Apart from the film scanner for m-film, a film scanner corresponding to the new film system has been proposed. When reading an image on a roll film with the new film scanner, the user loads the cartridge itself into the film scanner.

Here, a cartridge can be loaded into such a film scanner for a new film system regardless of whether the roll film has been developed or undeveloped. However, a film scanner cannot read an image on an undeveloped roll film. Further, since the original purpose of the film scanner is to read an image on the developed roll film, the film scanner is insufficient in shielding external light. Therefore, if an undeveloped roll film is loaded by mistake, the roll film may be pulled out of the cartridge and exposed carelessly.

Therefore, in the new film system, an indicator is provided on the cartridge so as to distinguish whether the roll film is undeveloped or not. Thus, the user can load the cartridge into the film scanner after seeing the indicator and determining whether or not the roll film stored in the cartridge has been developed.

[0007] Nevertheless, there is a possibility that an undeveloped roll film is loaded into a film scanner. Therefore, the film scanner for the new film system is configured not to perform an image reading operation even if a reading command is input from the host computer when the roll film has not been developed as a result of detecting the indicator.

Meanwhile, in the new film system, a magnetic storage area capable of magnetically recording arbitrary information on a roll film is provided. In this magnetic storage area,
Information is written when an image is taken by a camera having a magnetic recording function. Such magnetic information includes, for example, shooting date, exposure condition, title of a frame, and the like. In general, a film scanner for a new film system can read an image on a developed roll film, and can also read and write magnetic information recorded on the roll film.

[0009]

However, as is often the case with photographing with a camera, there is a case where it is desired to develop a photographed film under an exposure condition different from that at the time of photographing.
In the new film system, a camera having a magnetic recording function can be used to write exposure conditions in a magnetic storage area at the time of shooting. Usually, the roll film is developed according to the exposure conditions recorded in the magnetic storage area.

Therefore, if the magnetic information written at the time of photographing can be changed before developing the roll film, the magnetic storage area can be effectively used, which is very convenient. In addition, when an image is taken using a camera that does not have a magnetic recording function, it is possible to effectively use the magnetic storage area if the exposure conditions during development can be written to the magnetic storage area before developing the roll film. , Very convenient.

Here, since the film scanner for the new film system is provided with means for reading and writing magnetic information, it is possible to easily respond to a user's request by utilizing this means.

However, the conventional film scanner for a new film system does not operate when an undeveloped roll film is loaded. If the operation is performed, there is a danger of exposure because external light is not sufficiently shielded. Also, the image obtained by developing the roll film,
In some cases, it is desired that additional information such as a character string such as a shooting date and a picture be attached. Recent cameras include:
For example, there is a type in which a shooting date and the like can be imprinted in an image storage area at the time of shooting. However, there are almost no cameras capable of imprinting a title, a design, or the like at the time of shooting according to a user's request.

[0013] Therefore, it would be very convenient if a printing means was provided in a film scanner for a new film system so that desired information could be printed in an image storage area before developing a roll film. Can be easily met. However, the conventional film scanner for a new film system does not operate if the roll film is undeveloped as described above, and even if it operates, the film scanner is not sufficiently shielded from outside light, so there is a risk of exposure.

An object of the present invention is to provide an information reproducing apparatus and an image reading apparatus which can effectively utilize magnetic information of an undeveloped long film and can flexibly process an image.

In addition, the present invention is characterized in that burning is performed by optical information burning means.

(Operation) In the information reproducing apparatus according to the first aspect of the present invention, external light is prevented from entering the undeveloped long film by the light shielding portion. Therefore, even if the long film is undeveloped, the magnetic information stored in the magnetic storage area by the magnetic information reading means does not occur such that the image storage area is not carelessly exposed to external light. Can be read.

In the information reproducing apparatus according to the second aspect of the present invention, the determining means determines whether or not the long film has not been developed. Then, as a result of the determination, when the long film has not been developed, the control means drives the magnetic information reading means to read the magnetic information. As described above, even when the magnetic information is read from the undeveloped long film, since the light shielding portion prevents the incidence of external light, an adverse effect such as the careless exposure of the image storage area occurs. Nothing.

Therefore, the magnetic information stored in the magnetic storage area of the undeveloped long film can be notified to the outside. In the information reproducing apparatus according to the fourth aspect, the magnetic information read by the magnetic information reading means is updated and set by the setting means. Then, the updated magnetic information is written to the magnetic storage area by the magnetic information writing means. In this way, the degree of freedom in using the magnetic storage area in the undeveloped long film is expanded.

In the information reproducing apparatus according to the fifth aspect of the present invention, the burning means optically burns information into the image storage area based on the magnetic information read by the magnetic information reading means. Therefore, the degree of freedom of using the image storage area in the undeveloped long film is expanded. In the image reading apparatus according to the sixth aspect, the image reading unit reads an image in the image storage area of the long film illuminated by the illumination unit. However, when the determining means determines that the long film has not been developed, the prohibition control means prohibits the illumination by the illuminating means. Therefore, it is possible to prevent a situation in which the image storage area of the undeveloped long film is carelessly exposed by the light emitted from the illumination means.

In the image reading apparatus according to the seventh aspect of the present invention, during the period in which the illumination by the illumination means is prohibited by the inhibition control means, the magnetic information stored in the magnetic storage area by the magnetic information reading means is read. A read is performed. Therefore, even if the long film is undeveloped,
The magnetic information stored in the magnetic storage area can be read without causing such a situation that the image storage area is carelessly exposed by the light emitted from the illumination means.

In the image reading apparatus according to the eighth aspect of the present invention, during the period in which the illumination by the illumination means is prohibited by the inhibition control means, the optical information recording means optically writes information into the image storage area. Burning is performed. Therefore, information can be optically burned into the image storage area without causing a situation in which the image storage area of the undeveloped long film is carelessly exposed by the light emitted from the illumination means.

Is prevented from entering external light. That is, the image storage area 65 is not carelessly exposed to external light.

Further, in this embodiment, when the roll film 64 is not developed, the illumination light source 25 is set to the light emission stop mode. Therefore, irradiation of the light from the illumination light source 25 to the undeveloped roll film 64 is prevented. That is, the image storage area 65 is not carelessly exposed by the illumination light source 25. Therefore, even if the roll film 64 is undeveloped, the magnetic storage area 68 is not adversely affected on the image storage area 65 at all.
Magnetic information stored in the memory can be read.

In the next step S7, the CPU 44 compares the number of counters with the total number of designated frames stored in the memory 45 at the time of the read command, and determines whether or not magnetic information has been read for all designated frames. judge. If the determination in S7 is negative (NO), that is, if there remains a designated frame for which magnetic information has not been read, the CPU 44 returns to S4 again to perform processing. Then, the CPU 44 executes S
Until the determination of step 7 becomes affirmative (YES), S7 → S4 → (S
5 → S4 → S5) → S6 → S7, that is, the process of reading the magnetic information stored in the magnetic storage area 68 of the designated frame is repeated.

When the determination in S7 is affirmative (YES), that is, when the reading of the magnetic information of all the designated frames is completed, the CPU 4
No. 4 performs the processing after S8. In S8, the CPU 44
The magnetic information of each designated frame stored in the memory 45 is output to the host computer 41, and the system waits for the next command. The output of the read magnetic information to the host computer 41 may be performed between S6 and S7. That is, instead of storing the magnetic information of all designated frames in the memory 45 and then outputting the magnetic information to the host computer 41, the magnetic information may be output to the host computer 41 every time one magnetic information is read.

Then, the host computer 41 outputs the obtained magnetic information to the display device 42 and displays it on the monitor screen. As shown in FIG. 7, the contents of the displayed magnetic information include a shooting date and time, a film title, a frame title, an exposure condition, an aspect ratio, and the number of prints written by the camera at the time of shooting.

Therefore, the user can view the contents of the magnetic information of each frame displayed on the display device 42 and, if necessary, use the input device 43 to update and set the contents. For example, if the title of a frame already stored in the magnetic storage area “○ × Jidoushano Companion” is changed to “○
X Companion to a car ", or change the exposure conditions recorded during shooting.

In the case of a frame that has not been photographed when the roll film 64 is “unused” or “completely photographed” or a frame of the roll film 64 photographed using a camera having no magnetic recording function, The magnetic storage area 68 does not store magnetic information to be read. In these cases, the content of the magnetic information displayed on the display device 42 is blank, but the user can newly input the blank portion using the input device 43.

The contents of the magnetic information after the update setting or the new input can be written in the magnetic storage area 68 of the roll film 64 according to the procedure shown in FIG. Further, according to the procedure shown in FIG.
A character string indicating the contents of the magnetic information and a picture related to the contents can be optically burned into the image storage area 65 of the roll film 64.

Here, the contents of the magnetic information to be burned include the read magnetic information itself (one that is not updated).
The user can arbitrarily select whether to use it after updating or setting. In addition, the user can freely set the character size and typeface of the character string at the time of printing. Further, as a picture related to the content of the magnetic information, for example, a frame corresponding to a size assumed from an aspect ratio of an image, an illustration for imitating a frame title or a film title, a decorative frame, and the like can be considered. The user can also freely select and designate these patterns.

When the user wants to write the updated or newly input magnetic information in the magnetic storage area 68, the user specifies the frame number and write contents using the input device 43. The host computer 41
The information (write command) including the number of the designated frame input from the input device 43, the written content, the total number of these designated frames, and the like is sent to the CPU 44 of the image reading device.

When information such as a character string or a picture is to be imprinted on the image storage area 65, the user specifies the frame number, imprint content, imprint position, etc. using the input device 43. . The host computer 41 sends information (printing command) including the number of the designated frame, the content of the printing, the burning position, and the total number of these designated frames input from the input device 43 to the CPU of the image reading device.
Send to 44.

In FIG. 5, in S9, the CPU 44

While feeding the roll film 64 by driving the C motor 13, the magnetic signal processing circuit 49 is driven to check the frame number at the position of the burning light source 22.

In S11, as in S5, the CPU 44
Determines whether the frame number confirmed in S10 matches the designated frame number stored in the memory 45 at the time of the command. If the determination in S11 is negative (NO), that is, if the confirmed frame is not the designated frame, the CPU 44 performs the processing from S10 to S11 again.
Then, the CPU 44 determines that the determination in S11 is affirmative (YES).
The processing of S10 → S11 is repeated until the condition is satisfied.

When the determination in S11 is affirmative (YES), that is, when the confirmed frame is the designated frame, the CPU 44
Performs the processing after S12. In S12, the CPU 44
Determines whether the number of the designated frame matches the number of the designated frame to be subjected to the optical printing stored in the memory 45 at the time of the command.

Of the plurality of LEDs constituting the burn-in light source 22, the CPU 44
Is driven at the instructed timing.

That is, since the image storage area 65 on the roll film 64 is locally and successively exposed by the LEDs which are sequentially turned on, the specified position in the image storage area 65 of the specified frame is designated. Information is formed in a dot matrix and printed. For example, the image storage area 6
In the center of the upper part of 5, the title of the frame is "Companion of a car" and to the right is the shooting date "1996.6.1."
2 "is burned. Then, the CPU 44 updates the burning counter by one.

If the determination in S12 is negative (NO), that is, if the designated frame is not to be subjected to optical burning, the CPU 44 performs the processing in S14 without going through S13. In S14, the CPU 44 determines whether or not the designated frame number matches the designated frame number to be written, which is stored in the memory 45 at the time of the command.

If the determination in S14 is affirmative (YES), that is, if the designated frame is to be written, the CP
U44 performs the process of S15. In S15, the CPU 44
Moves the designated frame to the position of the magnetic head 23. Then, the CPU 44 drives the step motor 21 to feed the roll film 64 while the magnetic signal processing circuit 49
To write the updated magnetic information into the magnetic storage area 68 of the designated frame. Then, the write counter is updated by one.

If the determination in S13 is negative (NO), that is, if the designated frame is not a writing target, the CPU 44 performs the processing in S16 without going through S15. In S16, the CPU 44 compares the numbers of the burning counter and the writing counter with the total number of designated frames stored in the memory 45 at the time of the command, and performs the optical burning and the writing of the magnetic information for all the designated frames. It is determined whether or not both have been completed.

If the determination in S16 is negative (NO), that is, if the processing has not been completed for all the designated frames, C
The PU 44 returns to S10 again to perform the processing. And
The CPU 44 proceeds to S16 → S10 → (S11 → S10 → S11) → S1 until the determination in S16 becomes affirmative (YES).
The processing of 2 → (S13) → S14 → (S15) → S16 is repeated.

When the determination in S16 is affirmative (YES), that is, when all the designated frames have been completed, the CPU 44 proceeds to S1.

Is fed back into the cartridge 60, and the procedure ends.

Therefore, the user can take out the cartridge 60 from the cart room 10 of the image reading apparatus. In the roll film 64 stored in the cartridge 60 taken out after the above-described steps S1 to S17, desired information is burned into the image storage area 65 of the frame designated by the user, and the magnetic storage area 68 is updated. The magnetic information such as the exposure condition is written.

If the roll film 64 is "photographed", it may be developed as it is. Further, if the roll film 64 is “partially photographed” or “unused”, photographing can be performed for an un photographed frame, and development may be performed after photographing is completed. Next, the above procedures S1 to S1

In step 4, the process from S18 to S19 is performed again. And CP
U44 determines whether or not the determination in S19 is affirmative (YES).
Steps from 18 to S19 are repeated.

When the determination in S19 is affirmative (YES), that is, when the confirmed frame is the designated frame, the CPU 44
Performs the processing after S20. In S20, the CPU 44

When the reading of one frame is completed, the counter is updated by one.

The host computer 41 forms the image data of the image storage area 65 of the roll film 64 from the line data sequentially sent from the image reading device. Then, the host computer 41 displays the image data on the monitor screen of the display device 42. As shown in FIG. 8, it is confirmed that the frame title 81, the shooting date 82, and the like have been burned into the image storage area 65 as instructed by the user.

In S21, the CPU 44 compares the number of counters with the total number of designated frames stored in the memory 45 at the time of the read command, and determines whether or not magnetic information has been read for all designated frames. If the determination in S21 is negative (NO), that is, if image reading has not been completed for all designated frames, the CPU 44 returns to S18 again to perform processing. Then, the CPU 44
S21 → S1 until the determination of S21 becomes affirmative (YES)
8 → (S19 → S18 → S19) → S20 → S21 are repeated.

When the determination in S21 is affirmative (YES), that is, when the process has been completed for all the designated frames, the CPU 44 proceeds to S2.
Step 2 is performed. In S22, upon receiving the ejection command from the host computer 41, the CPU 44 inverts the DC motor 13 to drive the roll film 64 in reverse.
