Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a film cartridge lacking semiconductor memory.

For example, a camera that records predetermined information about all the frames photographed on an IC card was developed in Japanese Patent Application Laid-open No. 62-20.
This is proposed in Publication No. 8029.

This predetermined information includes trimming information that instructs printing only a predetermined portion of the image, color temperature information, and the number of copies to be printed.

Further, a film cartridge equipped with a RAM for storing film data such as film sensitivity information and photographic data such as exposure compensation amount has been proposed in Japanese Patent Laid-Open No. 154720/1983. In the system disclosed in this publication, a part of the storage area is provided with an area for storing the number of film sheets (remaining number), and the number of film sheets is decreased by 1 each time a photograph is taken, so that the recording means can be used in place of a film counter. ing. Furthermore, when all the images have been photographed, sensitization development data, filter data, and exposure correction data are recorded on the recording medium.

By the way, in the camera system described in Japanese Unexamined Patent Publication No. 62-208029, the IC card and film cartridge are separate, so many IC cards and In places that handle film cartridges, there is a risk that the IC card and film cartridge may be incorrectly associated with each other, resulting in printing based on incorrect trimming instructions.

Furthermore, in the film cartridge shown in Japanese Patent Application Laid-Open No. 154720/1984, exposure compensation data etc. are recorded when all shooting is completed, making it possible to record data for each frame. No exception.

CL is an oscillator that outputs a clock to the microcomputer CPU and the memory in the cartridge. AC consists of 7 accessories including electronic flash device, data imprint device, lens, winder and others.

FIG. 3 is a schematic 70-chart 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 it is in the middle of winding,
The process moves to step #3, and the film F is wound until the winding is completed. When the winding is completed, the process moves to step #4, and it is checked whether all the switches in the sequence switch group SA other than the winding completion switch are normal.
That is, it is determined 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 it is normal, the process moves to step #6, and a start signal is sent to the photometric colorimeter LM to perform photometry.
Start color measurement and distance measurement.

Next, in step #7, lens information is input from the lens information output section LS, and in step #8, lens information is input from the 7 accessories AC.
The accessory information is input, the status of the setting switch group SB is input in step #9, and the input setting switch information is processed in step #10. That is, it is determined whether the shutter speed, aperture value, photographing mode, trimming designation, exposure standard 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.

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 a 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 #16 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 has been operated, the process moves to step #17, and after inputting the clock information from the clock mechanism TM, communication with the memory in the film cartridge is performed in step #18. This communication is performed according to the algorithm shown in FIG. As a result, various information transmitted from the camera body 1 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, the process moves to step #20, where a mark is imprinted on the film F indicating the correspondence between the address of the memory M in the film cartridge and the film in which predetermined information is stored at that address. That is, mark imprinting part PR
A mark is imprinted on the film F by lighting up the light emitting diode 12 at. This mark is imprinted on the film F by predetermined information stored in the memory in the cartridge (trimming information, color temperature information, film frame number, number of prints, exposure standard information, year, month, day, hour, minute, second, and various shooting information). information,
This is to make the photographing number of the film F storing laboratory information, etc.) correspond to the address of the memory storing 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 photographing Tv value calculated in step #13, 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 22, a signal indicating that the release has been made is output to each section, and each section is reset. Next, wait for exposure control to be completed in step #23, then return to step #2, wind the film F, and set the film counter to 1.
After advancing the frame (repeating steps #2 and #3), repeat the above process again. In addition, instead of repeating this, when the photometry 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, by inputting the address counter in the memory in the cartridge, the number of frames to be photographed may be determined and the film counter displayed.

Other operations performed within the camera include changing the viewfinder field of view when trimming mode (details are shown in Japanese Patent Application Laid-Open No. 62-50737, for example), and changing the field of view in trimming mode. Pseudo focal length (
Exposure calculation according to the combination of the focal length of the photographing lens and the cropping magnification) and changing the irradiation range of 7 rays, limit data of the cropping magnification from the ROM-IC23 (ensuring the graininess of the printed photo) Therefore, the pseudo focal length is limited according to the limit of the enlargement magnification when enlarging and printing, the trimming mode is prohibited when data indicating that it is a positive film is input from the ROM-IC23, and the trimming mode is prohibited from the ROM-IC23. Enter the expiration date data of the film and check whether it is within the expiration date using the time information. If the expiry date has expired, a warning will be issued and/or the camera will be prohibited from taking pictures.

Furthermore, a light emitting diode 12 is provided for imprinting a mark that associates the address of the memory in the ROM-IC 23 with the frame number of the film. There is a frame-by-frame hood (e.g., a barcode) that is easy to read in the processing system and a number that is visible directly to the photographer on the developed film. Alternatively, since it is possible to associate the address with a book of film by reading it in the film processing system and counting the marks, it is sufficient to imprint only one point as shown in the figure. Furthermore, it is possible to imprint a mark only at the position corresponding to the 1st # (2) of the film, and then directly detect the image being photographed, count it, and associate it with the address. Add a special symbol (for example, a cutout, notch) to the first frame of the image, so that the camera starts shooting from that position, and from now on, the number of images being photographed is associated with the address. Alternatively, the film maker may put the code 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 will use this cutout or notch. By positioning each frame, the photographed frame, the latent image code and frame number, and the address of the memory of the ROM-IC 23 may be associated with each other. The cord may be provided by a cutout.

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 related to power supply.

φ is a system clock for circuit operation, and is input from the outside. CE is a circuit selection signal that has the functions of controlling circuit operation and serial data input/output DIN and DOUT terminals, which will be described later.It is input from the outside and allows data input/output at a low level.1. :: Naru,
CL K , D I N + D OUT Hashi'
) are communication terminals for serial clock, serial 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 the Higl+ level to the Lou+ level, it is sent to the DI via the switch buffers 222 and 223.
The Ni terminal and the DOUT terminal are connected to a serial reception register and a serial transmission register, respectively. CE double signal Low
After the change to the level, the serial data input from the DINi child is taken into the serial reception register 202 in synchronization with the serial clock input from the CLK terminal.
The received data latch 203 latches the received data.

The first byte of data input from the outside is input II.
It is latched into the mode register 221 by the I 611 unit 214 and the timing control circuit 201.

The mode register 221 is an 8-bit register with b7
+bgwbs is connected to the address decoder 212 as an address signal for specifying the upper three bits of the address of the memory cell 220. +34 of the mode register 221 is a control signal for specifying whether the memory cell is in write mode or read mode, and is connected to the output control unit 218 via the input control unit 214 or inverter 224. In the mode, input data is transferred from the input control unit 214 to the data buffer 7217 via the bus 206.

In addition, in the read mode, data from the data buffer T217 is transmitted from the bus 206 via the output control unit 218 to the data latch 204 and the serial transmission register 205.
lead to.

Next, 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, it is a non-addressing system, and the address for the memory cell is not specified from an external device, and the address signal generated by the internal 7 address counter 210 becomes the address for the memory cell. Therefore, the mode register 221 is the address selection circuit 211.
is connected to transfer the signal from address counter 210 to address decoder 212. 7 dress counter 210
is written by the timing control circuit 201 so that each time one frame of information is written into the memory cell 220, the process automatically advances to the next address.

Further, when the control bit b of the mode register 221 is 0, the addressing method is used, and the address for the memory cell is input as the second byte as serial data via the DIN terminal. This address information is input to the input control unit 214.
The counter register 207 is preset via the counter register 207. This data is then led to an address decoder 212 via an address selection circuit 211, and further to an address buffer 213, where it becomes address designation information for a memory cell. The counter register 221 is configured by the counter register 201 to automatically increment while the CE multiplication signal is "L" so that when several pieces of data are transferred in succession, it is not necessary to specify an address each time. controlled.

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 216 unique to E2PROM are connected to the memory cell 220.

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, modes {circle over (2)} and {circle around (2)} indicate the access method to the memory within the cartridge.

Mode I is a simple type, ie, a non-addressing method in which information is written and read without specifying an address, and mode (2) indicates a method in which 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, only necessary information can be handled, and the amount of information that can be handled increases. On the other hand, it has the disadvantage that processing is complicated.

The memory in the car +7 in this embodiment 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. At #24, communication mode designation data is set in the serial transmission register in the CPU. Here, the communication mode designation data is composed of 8 bits, and each bit has a meaning corresponding to each bit of the mode register 221 in FIG. 4 described above.

Since this is the read mode of mode (non-addressing method), b, = 1, l), = 1. 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 inside the cartridge becomes
Setting is made to a non-addressing data transmission mode. Therefore, in #27, when the serial clock is sent to the cartridge, predetermined data is input from the memory inside the cartridge to the CPU. The CPU stores the received data in the corresponding RAM, and again sends the serial clock for 1 byte at #29. The in-cartridge memory 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 HigI+ level, thereby ending the process.

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

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

First, in #32, communication mode designation data is set in the transmission register within the device. In this case, =1, b, =φ
Keep it. After the circuit selection signal CE is set to "L" in #33, the data is sent out in #34.The information to be recorded is then set in the transmission register in #35, and transmitted in #36.

Below, in #37 to #40, I35. By repeating the same sequence as #36, a plurality of pieces of information can be recorded in the memory within the cartridge. When the transmission is completed, the CE signal is raised to "H" level in #41, thereby ending the process. The number of types of information to be transmitted in this case is predetermined, and the order thereof 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 7 using the addressing method, and FIG. 8 is a 70-chart of a device that records information using the same method.

In each @42.954, communication mode designation data is similarly set in the data transmission register in the CPU. #
In #42, l), = φ, b, = 1, and in #54, l

After setting the CE double signal to ``L'' level with 5, @44.95
At step 6, a serial communication clock is transmitted to the cartridge, and communication mode designation data is also sent out, and the memories in the cartridge each operate in the designated mode.

#45. In #57, the CPU sets the address of the information to be read or recorded in the memory in the cartridge in the transmission register, and sends $46. Send at #58.

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, the address of the information is specified first and then the information can be exchanged, so the 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 a 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 31+it device designation bits of the mode register described above. As a result, the area of the memory cell used differs depending on each device. The area is
As shown in the figure, each area recorded by the camera, DP shop, laboratory, common area where common information such as film information that is used by the camera, DP shop, laboratory, etc. It is divided into @area. Here, for example, the camera usage area cannot be used only by the camera (even if it is a lab device, it is possible to read the information if the device specification data corresponding to the camera is sent when specifying the mode mentioned 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 at predetermined addresses.

The spare area from address OAH to address 1φH in the figure is an area provided when it is desired to record short sentences, information such as photographing location, etc.

FIG. 10 is a process explanatory diagram showing the flow of film and ROM-IC between user [1, DP agency, and laboratory L. 1J-) Ridge is on camera eight! ! When the film is loaded, the film information (sensitivity, etc.) stored in the memory is input to camera A (■).

It is also possible to specify and confirm orders for reprints by viewing the released film on TV at a DP distributor.

In laboratories, many rolls of film are spliced together for processing during development and printing, but in such cases, the information 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.

The storage parts 71 and 72 are integrated by a presser metal fitting.

The ROM-IC storage section 71 shown above is removed from the film container (film storage section 72) for photographing at a distributor, photofinishing laboratory, or mini-lab device, and the ROM-IC storage section 71 shown in FIG. The film is attached to a film container (film storage section) in the same manner as in the various configurations described above and returned to the photographer.

Figure f517 is an example of another film container. In this example, the side wall of the film storage portion 92 is flat, and the ROM-IC storage portion 91 is attached to this flat portion in the same manner as described above. Fig. 18 shows the ROM-IC storage part 91 in Fig. Pt517 and the film storage part 94 for viewing and/or storage.
It is a figure attached to the back part of. Further, the image shown in FIG. 118 may be used as a photographic film cartridge. In this way, when the same film container is used for photographing, viewing, and/or storage, there is no need to remove the film storage section and the ROM-IC storage section (-they can be imaged).

Although roll film containers have been described in the examples, the present invention can also be applied to sheet film containers. Furthermore, although the memory section is an example of E2FROM, it has a built-in battery and is backed up by this battery.
AM may be used.Furthermore, when writing data as an EPROM, a high voltage for writing may be applied from an external device.Furthermore, information specific to the film may be transferred to the RO.
The memory section in which data is stored in M and 8-bit readout is performed may be the non-volatile memory mentioned above.Furthermore, although the memory section and other circuit sections are integrated into one chip, the memory section can be implemented as a separate chip. The external circuit may be configured as a two-chip microcomputer (in addition, the external circuit may be configured as a one-chip microcomputer with a built-in nonvolatile memory, or two chips consisting of a nonvolatile memory and a one-chip microcomputer, or As for mounting, the example shown is direct wire bonding from the chip to the board, but it is also possible to encapsulate the chip in an IC package and then mount this IC package on the board. It is also possible to apply solder directly on the pad and use this solder to directly mount the chip on the board (bump method).As for the data communication method, an example of serial communication using a synchronous clock was shown, but the start-stop method Furthermore, in order to support various communication methods, a communication method switching signal may be input and the communication method corresponding to this signal may be adopted. It may be possible to perform parallel data communication when handling a large number of film containers. In this case, parallel data can be provided by providing a terminal for parallel communication on the back side where the chip is mounted. .

In devices (particularly cameras) that use a film container, data may be read without sending address data, and address data and write data may be sent when writing.

The originator! As mentioned above, with the film cartridge of the present invention, photographic data is stored in a different memory area each time a photograph is taken, so that the photographic data of any photographic frame can be retrieved without erasing the previously stored photographic data. You can know. In addition, since the semiconductor memory is integrated into the film cartridge, there is no chance of erroneously associating the semiconductor memory with the film cartridge at a DP shop or photo lab.
