Description

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

A camera has been proposed in which it is possible to specify the desired trimming to the laboratory by imprinting the rice distortion trimming information onto the film at the same time as the photograph is taken (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. ! +1, I was only able to capture a small amount of information such as cropping information.

Therefore, it is conceivable to record this information electronically or magnetically other than on film. In this case, compared to film, where the space to record information is severely limited, there is no such constraint, a sufficiently large storage capacity can be used, and a large amount of shooting information or laboratory information can be recorded. be able to. In addition, since electronic or magnetic recording is performed, it is difficult to accurately transmit imaging information or laboratory information to a recording medium and from the recording medium to terminal equipment or laboratory equipment. This allows accurate correspondence between film and recording media, and is effective in promoting automation of processing at DP distributors and laboratories.

013 In this data recording camera using an electronic or magnetic recording medium, when the film that has been shot is sent to the laboratory, this recording medium must also be sent at the same time.

That is, it is necessary to be able to freely attach and detach the recording medium separately from the film. However, in this case, the following problem occurs.

In other words, if the recording medium is removed from its mounting section while information is being recorded on the recording medium, or conversely, the recording medium is inserted into the mounting section midway through, the correct information may not be recorded on the recording medium. It's gone.

Further, if the recording medium is removed when the middle part of the film is at the exposure position, frames on which information is recorded by the recording medium and frames where information is not recorded will coexist in one film. In this case, when printing in a laboratory (photography laboratory), it becomes impossible to determine which frame of the film corresponds to the information recorded on the recording medium.

What's more, if you take a picture with a recording medium that records information from another data recording camera or a recording medium that records information about another film,
The frames of the film and the information on the recording medium do not correspond at all.

It is an object of the present invention to prevent such inconveniences from occurring and to make it possible to clarify the correspondence between information recorded on a recording medium and a film.

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

That is, the data recording camera of the present invention includes a recording medium mounting section, which is provided inside the camera at a place that can be attached and detached with the back cover open, and into which an electronic or magnetic recording medium other than film is attached, and a camera body. and a signal transmitting means for receiving a signal of photographing information or laboratory information from the recording medium and transmitting the signal to the recording medium.

In this configuration, "electronic or magnetic recording medium"
That is, electronic recording media! This indicates that the recording medium may be either a physical recording medium or an electronic and magnetic recording medium.

In addition, "imaging information or laboratory information" indicates that it may be any of imaging information, laboratory information 9 imaging information, and laboratory information.
Color temperature information, exposure standard information, information such as year, month, date, 2 hours, minutes, seconds, shutter speed Tv, aperture value Av, subject brightness By
, whether or not to use a flash, exposure information such as exposure compensation, number of shots (cumulative number of shirt releases for the camera), serial number (consecutive number from any frame), camera type, lens type, filter type. It includes at least one information such as information on the type and size of the subject, and may be one that excludes one or more arbitrary pieces of information.

Also, "lab information" refers to trimming information.

Color temperature information, exposure standard information, and film size.

It includes at least one of information such as film frame number, number of prints, print size, sensitization development, slide creation, special processing, year, month, day, hour, minute, and second.

Note that, by definition, imaging information and laboratory information may overlap.

standing shellfish The effects of this configuration are as follows.

That is, when a signal of shooting information or laboratory information is output from the camera body with a recording medium attached to the recording medium attachment section, this is transmitted to the recording medium via the signal transmission means, and the recording medium transmits the information. Record.

On the other hand, the back cover of a single film is closed until the photographer finishes shooting with that film and needs to take out the film.

The recording medium loading section is provided inside the camera, and the recording medium is loaded into the loading section, so the recording medium will not be removed until the camera back is opened when it is necessary to remove the film. .

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 1 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
is the microcomputer CPU of IC card B.

Enter the information about the characteristics of the IC card B sent from the user, and determine in step 2 whether or not the IC card B is normal and compatible with this camera system. Specifically, compatibility, non-installation, incorrect installation, failure, etc. are determined. If IC card B is normal, enter the terminal code with ■.
Send to C card B. The terminal code is the camera,

This causes @ to stop the operation of the microcomputer CPU.

If it is determined in ■ that IC card B is not normal, a warning is displayed on the display unit DS indicating that the IC card B is not normal, such as non-conformity, non-installation, incorrect installation, failure, etc. in step ■, 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 diagram 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 #1, 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 the film is in the middle of winding, the process moves to step #3 and the film F is wound until winding is completed. When the winding is completed, the process moves to step #4, and it is determined whether all the switches other than the winding completion switch in the sequence switch group SA 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 coloring section LM, thereby starting photometry, coloring, 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 Processes the configured switch information. That is, it is determined whether the shutter speed, aperture value, photographing mode, trimming designation, exposure level designation, etc. have been changed by the setting switch group SB, and if so, the corresponding processing is performed.

In the next step #11, 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 #11 to calculate the Yangying Tv value and the Yangying 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 accessory AC 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 CPU of the IC card B
Communicate with I.

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 it is 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, a mark is imprinted on the film F by lighting up the light emitting diode 2 in the mark imprinting portion PH. To imprint this mark on film F, enter the specified information on IC card B (trimming information 1) temperature information, film frame number, number of prints, output standard information 3 year, month, day, 2 hours, minutes, and seconds.
(Various shooting information, lab information, subject size information, etc.)
This is to distinguish the film F in which the information is stored from other films. As a result, when the two types of films mentioned above coexist in the lab equipment, the film F that has information stored on the IC card B can be distinguished from the film that does not, and it can be linked with the IC card B. It becomes possible to take action. 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 communication Tv value calculated in step #12, the communication Av
The 0th step # starts exposure control that controls the shutter, aperture, etc. based on data necessary for exposure control such as values
In step 21, a signal indicating that the release has been released is output to each part, and each part is adjusted. 6Next, in step #22, wait for the exposure control to be completed, and return to step #2, where the film After winding the film and advancing the film counter one frame (repeat steps #2 and #3),
The above process is repeated again. Instead of repeating this process, the microcomputer CPU may be programmed to stop operating when the photometry switch is not operated (
(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 10' 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 communication between the two microcontrollers and the CPU must be performed 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 (011) and (111) command continuous trimming. Continuous trimming means making multiple types of prints with different trimming sizes from the same negative. That is, the code (011) is t 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), a mark ml+mz is shown which indicates that the film has predetermined information stored in the memory M of the IC card B. This mark mI
+mz will be detailed later.

FIG. 8 is a process explanatory diagram showing the flow of the TC card B between the user U, the DP agency, and the laboratory L. Solid arrows indicate objects (IC card B, film F, print P5
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 9 color temperature information, film frame number 3 number of prints.

Exposure standard information 2 Year Month Date 1 Hour Minute Second 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 I'C card reader/writer 32 that can be connected to it, the user U can use the terminal device 31 to send information such as the developing method, shooting location, short message, etc. to the IC card. B's memory M
It is also possible to store the information in (see broken line ■). This can be done not only when requesting development and printing from a DP agent, but also when ordering additional 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.
3, and the receptionist additionally records data such as the customer's name and telephone number on IC card B (see broken line ■). In the case of a customer who cannot perform the process indicated by the broken line (■), the items conventionally written on a paper bag, such as print size, number of prints, presence or absence of special processing, and contents, are recorded on IC card B. IC card reader/writer 3
3 has a switch corresponding to the entry field on the paper bag,
Handling is cumbersome.

IC card B and film F, which are accepted at the DP agency, are transported to lab L as a pair. In the laboratory L, the film F and the IC card B are set in the developing Ia 34, and development is performed based on the information input from the IC card B, and a negative film N is obtained (see broken line ■). Negative film N and IC card B are set in a printing machine (not shown), and printing is performed based on data input from IC card B to obtain 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 ■). The reader/writer 36 reads various information from the IC card B, such as the photographing time of Yang's image information 5, and through statistical processing of this information, it can be fed back to create a better photographic system (see broken line ■).

Negative film N, pudding) 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 in the laboratory L, 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.

IC 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. Yes, it is possible (see dashed line ■). Print P is stored in 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. (transmission between solid line ■ and solid line 0). In this way, user U can immediately take IC card B home. Therefore, since the user U can immediately use the IC card B for the next photographing, there is an advantage that the number of tC cards B that the user U possesses is small.

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, since the IC card B is attached to the TC card attachment portion XI on the inner side of the back cover 13 of the camera A as shown in FIG. Unless the back cover 13 is unexpectedly opened during the process even though there is no need to take it out, predetermined information about all the photographed frames of the film F is recorded on the IC card B. It is configured. The reason for this configuration is as follows.

In other words, if IC card B is designed to be attached to the outside of camera A, and IC card B can be removed from camera A or inserted into camera A at any time, then IC card B is removed from camera A during the process or during communication, or conversely, IC card B is inserted into camera A, or predetermined information is recorded up to a frame in the middle of another film. There is a possibility that IC 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, in this embodiment, the IC card B is placed in the IC card mounting portion X located inside the back cover 13 as described above.

It is configured so that it can be attached to.

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. It is not necessary to imprint these marks m1°m2 on all frames of the 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 m2 may be a mark m imprinted numerically in correspondence with the photographed frame number as shown in FIG.
Or mark all the pieces with dots as shown in Figure 7 (B) m! However, the numerical mark m has a higher degree of correspondence with the recorded information of 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.

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

In the above embodiment, the IC card mounting part X1 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.
In the former case, the IC card B cannot be inserted until 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.

In the above embodiment, the IC card mounting part X 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 X2 may be provided in the camera body 1 diagonally below the mounting section of the cartridge 7. In the former case, the rC 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) IC card B does not need to be a general IC card, and may have a shape and format unique to the camera system. Also, IC card B may have a built-in microcomputer, battery, and EEFROM. It may also be an EEPROM without a microcomputer or battery.

(ii) Although IC card B is used as the recording medium in the embodiment, 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, may be used as the recording medium. .

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

(iv> In the embodiment, the marks ml and m2 were imprinted on the film F, but this imprinting is not necessarily necessary.

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

That is, for a single film, the back cover is closed until the photographer has finished photographing with that film and needs to take out the film.

Since the recording medium mounting part is provided inside the camera and the recording medium is mounted in the mounting part, it becomes necessary to take out the film, and the recording medium cannot be taken out until the back cover is opened.

In other words, from the time when the film is loaded until the time when it becomes necessary to take out the film, the correspondence between the information recorded on the recording medium at the time of photographing and the film used for the photographing can be maintained.

Therefore, for example, when printing in a laboratory (photographic laboratory), if the printing is performed based on the laboratory information recorded on the recording medium, the printing will be performed as expected.

If the recording medium mounting part is provided on the inner side of the back cover as in the embodiment, it is possible to use a thin IC card with a very large storage capacity as the recording medium, and it also takes up less space inside the camera. It has the advantage that it requires little consideration and does not require major design changes.

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 back cover as described above, and ■ it is necessary in the case of a magnetic disk. It has advantages such as: no mechanical drive 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.
