Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a data recording camera capable of recording laboratory information such as trimming information.

A camera has been proposed that allows the laboratory to specify the desired trimming by imprinting the distortion trimming information on the film at the same time as shooting (Japanese Patent Laid-Open No. 54-267
(See Publication No. 21).

However, because this camera recorded information on film, there were strong space constraints and it was not possible to capture much information. That is, only a small amount of information such as trimming information could be imprinted.

Therefore, it is conceivable to record this information electronically or magnetically other than on film. In this case, compared to film, where the space for recording information is severely restricted, there is no such restriction, and a sufficiently large storage capacity can be used, allowing a large amount of laboratory information to be recorded. . Also, to perform electronic or magnetic recording;
It is possible to accurately transmit laboratory information signals to the recording medium and from the recording medium to laboratory equipment, and to ensure accurate correspondence between the film and the recording medium. This will be effective in promoting automation of processing in laboratories and laboratories.

However, when this electronic or magnetic recording medium coexists with a conventional film-based data recording camera, the following problems occur in the laboratory.

That is, film taken with a data recording camera that is capable of recording laboratory information on electronic or magnetic recording media and film taken with a conventional camera that does not have such a recording means are stored in the laboratory (processing). If these cameras are used together, it is impossible for laboratory equipment to automatically distinguish which camera a given film was shot with.

If it is misidentified, a printing error will occur.

In order to distinguish between the two, it is necessary to know in advance which format the film is, either verbally or through notes, at a DP distributor or laboratory, but it would be extremely difficult to confirm this one by one for so many films. This is troublesome, and this leads to an increase in printing costs.

The present invention has been made in view of these circumstances, and even when the two types of films mentioned above are mixed, they can be clearly and automatically distinguished, thereby preventing printing errors and increasing printing costs. The purpose is to make it possible to suppress

The present invention for divination has the following configuration in order to solve the above-mentioned problems.

That is, the present invention includes a film mounting section, a mounting section for an electronic or magnetic recording medium other than film, a laboratory information signal generating means, and an output signal from the laboratory information signal generating means for recording.

That is, when the laboratory information signal generation means is driven with the recording medium mounted on the recording medium loading section, a laboratory information signal is generated, which is transmitted to the recording medium via the signal transmission means, and the recording medium is Record the lab information.

On the other hand, the mark imprinting means imprints onto the film a mark indicating that laboratory information has been recorded on the recording medium.

FIG. 5 is a flow chart showing the transmission and reception of signals between the data recording camera A and the IC card B.

This will be explained below.

In step (2), reset the IC card B by the microcomputer CPU of the camera body 1. ■ Microcomputer cp of IC card B
u, is ANSWER To R by the reset signal.
Executes a process called ESET. In this process, information necessary for the microcomputer CPU of the camera body l to determine the predetermined characteristics of the IC card B is output. The determination of the characteristics includes, for example, whether the IC card has power supply voltage, frequency, etc. that are compatible with this camera system. ■Microcomputer CPU of camera body 1
inputs the information about the characteristics of IC card B sent from the microcomputer CPUI of IC card B, and determines whether the IC card B is normal and compatible with this camera system in step 2. Specifically, compatibility, non-installation, incorrect installation, failure, etc. are determined. If IC card B is normal, the terminal code is sent to IC card B in step (■). The terminal code differs depending on the terminal such as a camera, a reader/writer for a DP distributor, an automatic printer in a laboratory, or a personal computer for home use. Therefore, the microcomputer CPU of the IC card B determines in which terminal it is attached based on the terminal code received in step (3), and selects an area in the memory M that can be accessed. This is to prevent data from changing unexpectedly by limiting the data that can be accessed depending on the terminal.

The microcomputer CPU of the camera body 1 then outputs to the IC card B information indicating the contents of the communication, such as what kind of information is to be communicated and the direction of the communication. The microcomputer CPU of IC card B inputs the information in ■ and prepares for communication. 6 Next, [F], 0
The microcomputer CPU of the camera body L and the microcomputer CPU1 of the IC card B exchange information such as image information, laboratory information, etc. Various information sent from the camera body 1 side is transferred to the microcomputer CPU of the IC card B. It is stored in memory M. When the communication is completed, press ■ to connect the microcomputer CPU of the camera body l.
is the microcomputer CPU of IC card B.

As a result, the operation of the microcomputer CPU+ is stopped at (3).

If it is determined in ■ that IC card B is not normal, a warning indicating that it is not normal, such as non-conformity, not installed, incorrectly installed, or malfunction is displayed in step ■ on the display unit DS, and then
Process.

The above algorithm is exactly the same not only for camera terminals, but also for terminals such as printers/writers for DP distributors, developing machines in laboratories, printing machines, and personal computers for home use.

FIG. 6 is a schematic flowchart showing the operation of the microcomputer CPU of the camera body 1. This will be explained below.

The microcomputer CPU is started by turning on the power supply BA of the camera body 1 or turning on, for example, a photometry switch. In step #l, the status of the sequence switch group SA is input, and in step #2, it is determined whether winding of the film F is completed.

If winding is in progress, the process moves to step #3, and when winding is completed, the process moves to step #4, where the film F is wound until the winding is completed. It is determined whether all the switches other than the above are normal, that is, whether photography is possible. If not normal, step #5
to stop the operation of the microcomputer CPU. If normal, the process moves to step #6, and a start signal is sent to the photometric/colorimetric section LM, thereby starting photometry, colorimetry, and distance measurement.

Next, in step #7, lens information is input from the lens information output section LS, in step #8, accessory information is input from the accessory AC, in step #9, the state of the setting switch group SB is input, and in step #10, the input In other words, it is determined whether the shutter speed, aperture value, shooting mode, trimming specification 9 exposure standard specification, etc. has been changed by the setting switch group SB, and if so, the corresponding setting switch information is processed. Perform processing.

In the next step #1), information obtained as a result of photometry, colorimetry, and distance measurement started in step #6 is input. and,
In step #12, exposure calculation is performed based on the information input in steps #7 to #1) to calculate the shooting Tv value and shooting AV value.
Calculate the data necessary for exposure control, such as values, and proceed to step #1
3, the calculated value is displayed on the display section DS. In step #14, the calculated value and other information necessary for the seven accessory ACs are output to the accessory AC.

The microcomputer CPU repeatedly executes a series of sequences from step #4 to step #14 until a release operation is performed.

Note that this series of sequences may be programmed to stop if the release operation is not performed within a predetermined time, or may be programmed to repeat only while the metering switch is being operated. (not shown).

In step #15 following step #14, it is determined whether a release operation has been performed. If no operation has been performed, the process returns to step #4. If it has been operated, the process moves to step #16, and after inputting the clock information from the clock mechanism TM, the microcomputer CP of the IC card B
Communicate with U + .

This communication is performed according to the algorithm shown in FIG. 5, and various information transmitted from the camera body 1 side is thereby recorded in the memory M of the IC card B.

In step #18, it is determined whether the communication was performed normally. If normal, the process moves to step #19, and a mark is imprinted on the film F to indicate that the film has predetermined information stored in the memory M of the IC card B.

That is, the light emitting diode 12 in the mark imprinting part PR is turned on to imprint a mark on the film F. This mark is imprinted on the film F by using predetermined information (trimming information 9, temperature information, film temperature information, etc.) on the IC card B. To distinguish film F, which stores frame number, number of prints, exposure standard information, year, month, day, hour, minute, second, various shooting information, laboratory information, subject size information, etc., from other films. It is. As a result, if the two types of films mentioned above are mixed in the lab equipment, IC card B
It becomes possible to make a correspondence with the IC card B while distinguishing the film F on which information is stored from the film on which information is not stored. The details of this will be described later.

After step #19 or when the communication is not normal as determined in step #18, the process moves to step #20, and the photographing Tv value calculated in step #12, the photographing Av
Exposure control that controls the shutter, aperture, etc. is started based on data necessary for exposure control such as values. Next step #
At step 21, a signal indicating that the release has been released is output to each section, and each section is reset.Next, at step #22, wait for the exposure control to be completed, and then return to step #2, where the film F is wound. , set the film counter to 1
After advancing the frame (repeat steps #2, #3), repeat the above process again.Instead of repeating this, if the metering switch is not operated, the microcomputer C
The PU may be programmed to stop operating (not shown).

In the flow of FIG. 6, the microcomputer CPU of the camera body 1 and the microcomputer CPU of the IC card B.

Communication between the camera and the camera is performed for each release operation.

If communication is performed during photometry, the current allowable number of writes to EEFROM (memory M) (
104 to 105 times). In the case of an IC card that does not use EEFROM as the memory M, for example, an IC card that has a built-in battery and RAM, the number of allowed writes is sufficiently large, so it is necessary to communicate between the two microcontrollers CPU during photometry. I can do it.

Next, an example of trimming information, which is one of the lab information among various types of information stored in the memory M of the IC card B from the microcomputer CPU of the camera body 1, will be described with reference to the following table.

(Margin below) In this table, a, b, c, and d are the range of trimming prints. (A) and (B) in FIG. 7 show the areas a, b, and c to be trimmed and printed.

d is shown on film F.

Codes (01)) and (1)1) command continuous trimming. Continuous trimming means making multiple types of prints with different trimming sizes from the same negative. That is, code (01)) is used as trimming information.
When stored in the memory M of the C card B, the printer is controlled by this trimming information at the time of printing, and three types of prints are obtained: a print without trimming, a print with the trimming range a, and a print with the trimming range A.

In FIGS. 7(A) and 7(B), marks m, , m, indicating that the film has predetermined information stored in the memory M of the rc card B are shown. This mark m,,m
Details regarding z will be described later.

FIG. 8 is a process explanatory diagram showing the flow of the IC card B between the user U, the DP agency, and the laboratory 5. Solid arrows indicate objects (IC card B, film F, print P,
The flow of the negative film N) is shown, and the broken line arrows show the input/output of data regarding the IC card B.

When user U takes a photo, microcontroller C of camera A
Trimming information output from PU 1. Temperature information, film frame number, number of prints.

Exposure standard information 1 year month date 2 hours minutes seconds 1 various shooting information.

Predetermined information such as information on the size of the subject is stored in the memory M of the IC card B (see broken line ■). If the user U has a terminal device 31 such as a personal computer and an IC card reader/writer 32 that can be connected to the terminal device 31, the user U can use it to specify the developing method, shooting location, short message, etc. on the IC card B. It is also possible to store the image in the memory M (see broken line ■).This can be done not only when requesting development and printing from a DP agent, but also when ordering extra prints.

The IC card B on which predetermined information has been recorded in this way and the corresponding film F are made into a pair and taken to a DP agency.

At the DP agency, a dedicated IC card reader/writer 3 is available.
Place IC card B in 3, and the receptionist will additionally record data such as number 1 customer's name, phone number, etc. on IC card B (see dashed line ■). , print size, number of prints, presence or absence of special processing, contents, and other items that were conventionally written on paper bags are recorded on IC card B. IC card reader/writer 3
3 has a switch corresponding to the entry field on the paper bag,
It is easy to handle.

IC card B and film F, which are accepted at the DP agency, are transported to lab L as a pair. In laboratory L, film F and IC card B are set in the developing machine 34, and development is performed based on the information input from IC card B, resulting in negative film N (see broken line ■).
, a negative film N and an IC card B are set in a printing machine (not shown), and printing is performed based on data input from the IC card B to obtain a print P.

In this case, information such as the details of the process, the number of prints, and the management number are recorded on the IC card B (see broken line ■). Photographing information is obtained from IC card B by reader/writer 36.

It is also possible to read various information such as when the photo was taken and, through statistical processing of this information, provide feedback to create a better photographic system (see dashed line ■).

Negative film N and print P obtained as above
The IC card B with the information added thereto is returned to the DP agency. At the DP agency, the IC card reader/writer 33 reads the information recorded on the IC card B by UboL, and automatically calculates and displays the fee (see broken line ■).

Note that if this IC card B can also be used as a cash card or credit card, the customer does not have to pay in cash.

RC card B is sent to user U from the DP agent.

When print P and negative film N are returned, user U
is a personal computer 31. Reader/writer 32
In addition to being able to read shooting information and processing information using the , it is also possible to record information by storing it in computer memory such as a magnetic disk, magnetic tape, or bubble memory, or by printing and transferring it onto recording paper. If it is possible (see the broken line ■), the print P is stored in the album 37.

Note that for users U who do not have the reader/writer 32, a service is also available in which a printout of the information recorded on the IC card B is returned at the same time at a DP agency or laboratory L.

After the IC card B returned to the user U records the necessary information in a computer memory or the like or records it on paper, it can be attached to the camera A again and used any number of times.

FIG. 9 is a process explanatory diagram showing another flow of IC card B. This will be explained below.

When the user U takes the film F and the IC card B to the DP agency, the recorded information on the IC card B is transferred to another recording medium B' exclusively for the laboratory L at the DP agency. Transfer to (transmission between solid line ■ and solid line [phase]). In this way, user U can immediately take IC card B home. Therefore, user U uses IC
Since the card B can be used immediately for the next photograph, there is an advantage that the number of IC cards B held by the user U can be reduced.

The rest of the flow shown in FIG. 9 is the same as the flow shown in FIG. 8, so the same parts and parts will be given the same reference numerals and the explanation will be omitted.

In the embodiment of the present invention, the IC card B is located at the inner portion of the back l1)3 of the camera A as shown in FIG.
Since the film F is installed in the card slot X+, there is no need to take out the film F installed in the camera A. IC card B is configured to record predetermined information about all the pieces that have been played. The reason for this configuration is as follows.

In other words, if IC card B is attached to the outside of camera A, and if IC card B can be removed from camera A or inserted into camera A at any time, then If IC card B is removed from camera A during communication or when IC card B is inserted into camera A, or if IC card B records predetermined information up to a frame in the middle of another film, There is a possibility that card B may be inserted. In such a case, frames with IC card information and frames without IC card information coexist in the same film F.

In that case, when printing at Lab L, the pieces and IC
Corresponding with card information becomes extremely difficult.

In order to overcome this difficulty, special measures must be taken, which not only increases costs but also imposes significant design constraints.

In order to prevent such inconvenience from occurring, the present embodiment is configured so that the IC card B is inserted into the IC card mounting portion X1 located on the inner side of the back cover 13 as described above.

However, even so, in the initial stage of the introduction of this camera system, there is a possibility that film taken with a camera that cannot record information on IC card B and film taken with this camera system will be mixed in laboratory L. Therefore, it becomes necessary to inform the printing machine in laboratory L that the film F is taken with this camera system, and to make correspondence between the film F and the IC card B.

For this reason, as shown in FIGS. 7(A) and 7(B), marks ml and m are imprinted on film F to indicate that it is film F with predetermined information recorded on IC card B. be. This mark m+.

It is not necessary to imprint m2 on all frames of film F. Even if only the first frame is imprinted, the film F and the IC card B can be made to correspond to each other using the information on the number of shots.

The marks ml and ml may be marks m1 that are numerically imprinted in correspondence with the photographed frame numbers as shown in FIG.
Alternatively, the marks mt may be imprinted as dots on all the pieces as shown in FIG. 7(B), however, the numerical marks m have a higher degree of correspondence with the information recorded on the IC card B.

Although not shown, it is possible to enter a unique identification code for each IC card B, and to imprint the identification code of IC card B along with the mark on the frame that is photographed with that IC card B installed. By doing so, it is possible to make the IC card B and the film F correspond to each other on a one-to-one basis, and the degree of correspondence between the two can be made extremely high.

The identification code of IC card B may be manually input by user U from camera A or a dedicated reader/writer 32, or it may be manually input by user U during the manufacturing process of IC card B, and then user U inputs the identification code of IC card B. An identification code may be selected at the time of purchase.

In the above embodiment, the rc card mounting part XI was provided in the inner part of the back cover 13 (the part closer to the back cover 13 than the film F), but the present invention is not limited to this. For example, as shown by the dotted line in FIG.
Alternatively, an IC card mounting section X3 may be provided diagonally below the mounting section of the cartridge 7 in the camera body 1. In the former case, the IC card B must be removed after the film F is removed. However, in the latter case, the IC card B can be taken out without removing the film F, as in the above embodiment. And the former,
In either of the latter cases, a RAM chip may be used as the recording medium.

The present invention also includes the following as examples.

(i) The IC card B does not have to be a general RC card, and may have a shape and format unique to the camera system. Further, the IC card B may have a built-in microcomputer, a battery, and an EEFROM, or may have only an EEFROM without a microcomputer and battery.

(ii) In the embodiment, an IC card B is used as the recording medium, but it is also possible to use something other than an IC card, such as a magnetic tape, a magnetic disk, or a non-volatile memory such as a magnetic bubble memory. Good too.

(iii) In the embodiment, a plurality of trimming ranges could be specified for the same screen, but it is not necessary to do so.

Fourth coming According to the present invention, the following effects are achieved.

In order to imprint a mark on the film that indicates that laboratory information has been recorded on an electronic or magnetic recording medium, the film must be photographed in a laboratory with a data recording camera that can record laboratory information on the recording medium. Even if there is a mixture of film taken with a conventional camera that does not have such a recording means, the two types of film can be clearly and automatically distinguished using laboratory equipment or the like.

Therefore, it is possible to prevent printing errors caused by misidentification of two types of films.

Furthermore, it is no longer necessary for the DP distributor or laboratory to know in advance which of the two types of film is used orally or by memo, and it becomes possible to suppress the increase in printing costs.

Furthermore, if a photograph is taken without a recording medium attached to the attachment section, or if a photograph is taken with an incompatible recording medium attached, the specified laboratory information will not be recorded on the recording medium. Even in such a case, if the mark is imprinted on the film, the correspondence between the film and the recording medium will be misaligned. However, as in the embodiment, the mark imprinting means,
If the drive is driven by the output of the means for detecting that laboratory information can be recorded on the recording medium, the mark will not be imprinted on the film in the above case.
This has the advantage that mismatching of the correspondence between the film and the recording medium can be prevented.

In addition, when an IC card is used as a recording medium as in the embodiment, ■ it is thin and can be easily attached to the inner part of the ML, and ■ the mechanical drive required in the case of a magnetic disk. It has advantages such as: no mechanism is required and it is advantageous in terms of space; 1) information can be written and read at very high speed; 2) it has excellent versatility and applicability.
