FIG. 3 is a schematic 70-chart showing the operation of the microcomputers CPt and J of the car body 1. This will be explained below.

The microcomputer CPU is started by turning on the power supply BA of the car body 1 or turning on, for example, a photometry switch. Step $1' The state of the Ck sequence switch group SA is input, and in step #2 it is determined whether winding of the film F is completed. If it is in the middle of winding, proceed to step #3, and when winding is completed, proceed to step #3, where the film F is wound until winding is completed.
Then, it is determined whether all the switches in the sequence switch group SA other than the winding completion switch are normal, that is, whether photography is possible. If it is not normal, the process moves to step #5 and the operation of the microcomputer CPU is stopped. 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 unit LS, in step #8, accessory information is input from the 7 accessories AC, in step #9'', the state of the C setting switch group SB is input, and in step #10 Processes the setting switch information input in .In other words, shutter speed,
It is determined at t1 whether the aperture value, photographing mode, cropping designation, exposure standard designation, etc. have been changed by the setting switch group SB, and if they have been changed, processing corresponding to the change is performed.

In the next step #11, information obtained as a result of photometry, colorimetry, and distance measurement started in step #6 is input.

In step #12, information necessary for photographing, such as film sensitivity and number of films, is input from the memory in the film cartridge. And step #13
Now, exposure calculation is performed based on the information input in steps #7 to #12 to calculate data necessary for exposure control such as the shooting Tv value and shooting Av value, and the calculated values are displayed on the display section DS in step #14. indicate. In step #15,
The calculated value and other information necessary for the 7-customer AC are output to the 7-customer AC.

The microcomputer CPU repeatedly executes a series of sequences from step #4 to step #15 until the release operation is performed.

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

In step #]6 following step #15, it is determined whether a release operation has been performed. If no operation has been performed, the process returns to step #4. If it is operated, move to step #17, totaling 11! After inputting the timing information from the FI structure TM, communication with the memory in the film cartridge is performed in step #]8 (this communication is performed according to the algorithm shown in FIG. 5). Various information transmitted from the first side is recorded in the memory M within the film cartridge.

In step #19, it is determined whether the communication was performed normally. If it is normal, move on to step #20 and record the address of memory M in the film cartridge and the prescribed information at that address! Imprint a mark indicating the correspondence of the film on the film F, that is, mark imprinting part PR.
A mark is imprinted on the film F by directly striking the light emitting guide 12 in the film F. This mark is imprinted on the film F by using predetermined information (trimming information, color temperature information, film frame number, number of prints) in the memory in the cartridge. , exposure standard information, year, month, day, hour, minute, second, various shooting information,
This is to make the photographing number of the film F that stores laboratory information, etc.) correspond to the number 7 of the memory that stores the corresponding information.

After step #20 or when the communication is not normal as determined in step #19, the process moves to step #21, and the shooting Tv value calculated in step #13 and the shooting AV
The 0th step # starts exposure control that controls the shutter, aperture, etc. based on data necessary for exposure control such as values
At step 22, a signal indicating that the release has been released is output to each section, and each section is reset.Next, the camera waits for exposure control to be completed at step well 23, returns to step well 2, and winds the film F. , set the film counter to 1
After advancing the frame (repeat steps #2 and #3), repeat the above process again.Instead of repeating this, if the photometering switch is not operated, the microcomputer CP
It may also be programmed to stop operation of U (not shown).

Furthermore, instead of advancing the film counter by one frame, the number of frames to be shot may be calculated and displayed on the film counter by inputting the counter into the 7 card in the memory in the cartridge.

Other operations performed within the camera include changing the field of view of the viewfinder when trimming mode (details are shown in W 62-50737, for example), and changing the field of view in trimming mode. Doubtful, t! !
, Exposure calculation according to the distance l1l (focus of the photographing lens, focal length N based on the combination of α distance and trimming magnification), changing the irradiation range of 7 rays, and trimming magnification limit data from the ROM-IC23 (printed In order to ensure the graininess of the photograph, the pseudo focal length is limited according to the limit of the enlargement magnification when enlarging and printing, and ROM-I C
Prohibition of trimming mode due to input of data indicating Bottfilm from 23, ROM-IC2
The expiry date data of the film from 3 is input, and whether or not it is within the expiry date is determined based on the clock information, and if it is outside the expiry date, a warning is issued and/or the camera is prohibited from photographing.

Further, a light emitting diode 12 is provided for imprinting a mark to associate the address of the memory in the ROM-IC 23 with the frame number of the film. There are codes that change from frame to frame (e.g., barcodes) that are easy to read within the processing system, and numbers that are directly visible to the photographer on the developed film. Alternatively, it is possible to make a correspondence with the 7 dresses by reading and counting the marks in the film processing system using a book of film. The mark may be imprinted only at the position corresponding to the first frame of the film, and from then on, the image being photographed may be directly detected, counted, and associated with the 7 dresses. Place a special symbol (for example, a notch) on the eye so that the camera starts taking pictures from that position, and from now on, the number of images taken is associated with the address. Alternatively, the film maker may place the hood and frame number as a latent image outside the film screen in advance, provide a cutout or notch for positioning each frame, and the camera uses this cutout or notch to locate each frame. By performing positioning, the photographed frame, the hood and frame number based on the latent image, and the 7th dress in the memory of the ROM-IC 23 may be associated with each other. A hood may be provided by the notch.

Next, the ROM-IC 23 will be explained according to FIG.

First, it has seven terminals for communication with the outside and for power supply. Vdd and GND are electric iP! It is a relationship.

φ is a system clock signal γ for circuit operation, and is input from the outside. CE is a circuit selection signal that has the function of controlling circuit operation and controlling serial data input/output DIN and DOUT terminals, which will be described later.It is input from the outside and enables data input/output at a low level. . CLK,
DIN and DOUT are terminals for serial communication, and serve as a serial clock, full data input, and serial data output, respectively.

Data communication with the outside is performed through these three lines.

When attached to the camera, power is supplied from the camera via Vdd and GND, and a system clock φ is also supplied.

The circuit selection signal CE is input to the timing control circuit 201, and when it changes from 111 level to Low level, it is input to DIN via switch buffer y222+223.
The DOUT terminal and the DOUT terminal are connected to a serial receiving register and a serial transmitting register, respectively. After the CE signal changes to Low level, serial data input from the DIN terminal is taken into the serial reception register 202 and latched by the reception gate latch 203 in synchronization with the serial clock input from the CLK terminal.

The first byte of data input from the outside is latched into the mode renoster 221 by the input control 1 section 214 and the timing control circuit 201.

Mode Reno Star 221 is an 8-bit Re No Star and is 7
．． bl, b are 11 connected to the address decoder 212 as 7 address signals for specifying the upper 3 bits of the address of the /Mori cell 220. Modere Nosta 221
Nosu is a control signal for specifying whether the memory cell is in write mode or read mode, and is connected to the output control section 218 via the input side AT section 214 or inverter 224, and is connected to the output control section 218 in the write mode. At times, input data is transferred from the input control unit 214 to the data buffer y217 via the bus 206.

In addition, in the read mode, data from the data buffer 7217 is controlled to be output from the bus 206 via the data latch 204 and serial transmission register 205 via 21B.
lead to.

Next, bl of the mode register 221 is the memory cell 220
This is a control bit for controlling the access method to . When this control bit is 1, the non-71/res method is used, and the address for the memory cell is not designated from an external device, and the address signal generated by the internal address counter 210 becomes the address for the memory cell. Therefore, b3 of the mode register 221 is the address selection circuit 21.
1 and transfers the signal from the 7 address counter 210 to the address decoder 212. address counter 21
0 is written by the timing control circuit 201 so as to automatically advance to the next address every time one frame of information is written into the seven-strip cell 220.

Further, when the control pin (bi) of the mode register 221 is 0, it is an addressing method, and the address for the memory cell is inputted as serial data as the second byte through the DIN terminal. This 7 dress information is input control unit 2】4
It is preset in the counter renostar 207 via. This data is then led to the address decoder 212 via the address selection circuit 211, and further to the address buffer T213, where it becomes address designation information for the memory cell. When the counter renoster 221 transfers several pieces of data in succession, the CE multiplication signal "L" is automatically incremented so that it is not necessary to specify an address each time. controlled by.

Also, although the explanation was omitted above, in order to read/write to the memory cell 220, the write/erase control unit 215
, and a high voltage generating section 21G specific to E'P ROM is a 7-moly cell 2201. :I is stopped down to ν.

Figures 5 to 8 show 7 of the sequence of exchanging information in a device capable of exchanging information with the memory inside the cartridge.
0-Chart.

In each figure, mode 1. II shows an access method to the memory inside the car ridge.

Mode I is an easy type, that is, a non-addressing method in which information is written and read without specifying an address, and mode 2 indicates a method in which seven addresses of information to be written and information to be read are specified. Mode (2) has simpler processing than mode (2), but it is limited in the amount of information that can be handled because it is not possible to specify only one particular piece of information out of a large amount of information. Since mode (2) is a direct addressing method, it is possible to handle only the necessary information and the number of information that can be handled is large.However, on the other hand, it has the disadvantage that processing is complicated.

In this embodiment, the in-cartridge memory is configured to be compatible with both types, as described above.

First, the information read routine in mode 1 will be explained with reference to FIG. In #24, the communication (r-mode designation data) is set in the serial transmission register in the CPU. A meaning is assigned to each bit.

Mode here! (Non-address method), read mode, so b, = 1, b, = I should be 0.Next, after setting the circuit selection signal CE to "L" in #25, #26
Now, send the data set in #24 to the cartridge.

As a result, the memory in the car ridge is set to the non-addressing data transmission mode as described above. Therefore, in step #27, when the serial number is sent to the cartridge, predetermined data is input from the memory in the cartridge to the CPU. CPIJ stores the received data in the corresponding RAM and returns it to #2.
9 sends 1 byte of serial clock. The memory in the cartridge 7 sends data to the CPU in the order determined by the address counter 210 as described above.

In #30, the CPU similarly stores the data in the RAM corresponding to the data. Thereafter, by repeating the sending of the clock and the storing of the clock into the RAM, it is possible to read out the determined information from the memory in the cartridge in a determined order.

Finally, in step #31, the CE multiplied signal is set to High level, thereby ending the process.

Here, the type and order of the information to be read out is such that the more frequently it is used, the earlier it is read out, and the less frequently used information is read out.
The order is determined to be later, with information regarding film speed, number of film frames, and latitude in that order.

FIG. 6 is a 70-chart when information of the Wi device is recorded in the memory in the cartridge using the non-addressing method.

First, in #32, communication mode designation data is set in the transmission register in the I11 device. In this case, =i, b
,=φ, and set the circuit selection signal CE to 'L'' at @33.
After that, the data is sent out in #34, then the information to be recorded is set in the transmission register in #35, and the information is transmitted in #36. Below, in #37 to #40, #35. By repeating the same sequence as #36, a plurality of pieces of information can be recorded in the memory within the cartridge. Once the transmission is complete, #4
The process ends by setting the CE double signal to the "H" level at 1. The number of types of information to be transmitted in this case is determined in advance,
The order is also predetermined. The order of the information here is also determined according to the importance of the information, as in the case described above. That is, the photographing year, month and day, trimming information, color temperature information, and various photographic information are recorded in this order.

Next, FIG. 7 is a 70-chart of a device that reads information from the memory in the cartridge using the addressing method, and FIG. 8 is a 70-chart of a device that records information using the same method.

Each #42. In #54, communication mode designation data is similarly set in the data transmission register in the CPU. #
In #42, =φ, b, =1, and in #54, bconiφ, l), =φ are set. Next is #43. After setting the CE double signal to 'L' level with $55, the serial communication clock is sent to the cartridge with #+4 and 95B, and communication mode designation data is also sent out, and the memory in the cartridge operates in the designated mode. Do it, #45
．． At #57, the CPU sets the address of the information to be read or recorded in the cartridge in the transmission register, and transmits it at 946.95B.

The memory in the cartridge sequentially sends information corresponding to the designated address to the CPU in accordance with the communication clock from the CPU in the read mode, and stores information from the CPU in the record mode. #47 and below,
The steps from #59 onwards are the same as those in the non-addressing method described above, so the explanation will be omitted.

In the addressing method, seven addresses of information can be specified first and then information can be exchanged, so necessary information can be accessed when needed.

The communication sequence and information above have been explained using the camera and the memory in the cartridge as an example, but it can also be used to specify the reception date and time, development and print processing methods, number of prints, etc.
The same flowchart can be used when recording print size etc. in the cartridge internal memory depending on the DP store, or when reading out processing information recorded in the laboratory. The same applies when reading information such as color temperature from the memory in a cartridge or recording a processing method in a developing device, a printer, etc. in a laboratory.

FIG. 9 shows the relationship between addresses and information of memory cells in the memory in the cartridge.

The address indicated by the upper 3 bits is obtained by decoding from the upper 3 bits of device designation bits of the mode register mentioned above. As a result, the area of the memory cell used differs depending on each device. As shown in the figure, the II area includes each area recorded by the camera, DP store, and laboratory, a common area where common information such as film information that is used by the camera, DP store, laboratory, etc. is recorded, and future development potential. It can be divided into two areas: the pre@area, which has been reconsidered. Here, for example, the camera usage fil area is not only usable by cameras; even if it is a lab device, it is possible to read information by sending the device specification data corresponding to the camera when specifying the mode described above. Any information within a memory cell can be accessed as needed.

The lower addresses are shown in hexadecimal notation to simplify the diagram. Each piece of data is stored in a predetermined order of a plurality of pieces of information corresponding to the frames of the film.

That is, year, month, day, trimming magnification, Av...
The information of the second frame starting from address 1φH is also in the same order. In this way, all information is stored in a predetermined 7 dons.

The spare area from OA 1-1 address to 1-to1 address in the diagram is as follows:
This is an area provided when you want to record short sentences, information such as shooting locations, etc.

At the DP agency, the cartridge is set in the dedicated cartridge memory league/writer 33, and the receptionist additionally records data such as number 9 customer's name and TLT talk number in the memory in the cart lip ( In the case of customers who are unable to perform the procedures described in (1) and (2) above, items such as print size, number of prints, presence or absence of special processing, and content, which were conventionally written on paper bags, are recorded in the cartridge. The cartridge league/writer 33 has switches corresponding to the entry fields on the paper bag, making handling convenient.

Film cartridges received at the DP agency are transported to laboratory L. In Lab L, the cartridge is set in the developing machine 34, and development is performed based on the information input from the memory in the cartridge, resulting in NEF film (■). and F1 are set in a printing machine (not shown),
Printing is performed based on the data input from the memory, and a print P is obtained.

In this case, information such as the details of the process, the number of prints, and the management number are recorded in the memory (■). The League/Writer 36 reads various information from the memory, such as shooting information and *shading time, performs statistical processing on this information, and feeds it back to create a better photographic system (■). The latter film is stored in another new car (Ridge N). You can also set the memory in the cartridge mentioned above to N! II is intimidated. This is to make the cartridge easier to handle considering systems such as the TV M Awards.

When the refrigeration N is returned, the user 〇 uses the personal combiator 31. The league/writer 32 can be used to read shooting information and processing ms, as well as porcelain disks and porcelain tapes.

Information can be recorded by being stored in computer memory such as bubble memory, or by being transferred onto recording paper by printing. Furthermore, based on the memory information, it is also possible to enjoy film images by directly viewing them on a television, or by changing trimming and color designations on the television.

Furthermore, for users U who do not have the League/Writer 32, it is also possible to provide a service in which a printout of the information recorded in the cartridge's memory can be returned at the same time at a DP agency or at Lab L. ,
It is also possible to specify and confirm orders for reprints by viewing the released film on TV at a DP distributor.

When developing and printing, FPO processes multiple rolls of film by splicing them together, but in such cases, the correspondence between each frame of the spliced film and the memory in the cartridge is extremely difficult. becomes difficult. Therefore, it becomes necessary to establish correspondence between film and memory.

Therefore, as shown in FIGS. 11(A) and 11(B), a mark-2 indicating the correspondence between the 7th address of the memory in which predetermined information is recorded and the film frame number is imprinted on the film F. There is. In the case of this mark 112, it is possible to make it correspond to the memory address by imprinting it only on the first frame.

Regarding this mark 11'+t-2, see FIG. 11 (A>
It may be a mark set that is imprinted numerically in correspondence with the frame number taken, such as 1 at the beginning of the film F.
It is also possible to use a mark spade 2 that imprints dots at 11 locations as shown in Fig. 11 (B), but numerical marks may be used.
