Description

[Detailed Description of the Invention] [Technical Field] The present invention provides a device that can be equipped with an IC card (inch-rated circuit card) in which information (data) necessary for operating a camera and actually taking pictures is stored in advance. This is about a camera that has been used.

[Prior art and its problems] In recent years, high-end eye reflex cameras, etc., which could only be used effectively by an experienced person, are equipped with a microcomputer, and this microcomputer controls the driving of the photographic lens. Autofocus eye reflex cameras, which automatically move the photographic lens to the focusing position, have been put into practical use, and this has created a huge impact among people who had previously given up on the camera because it was too difficult to operate. ing.

In this way, the system that enabled cameras to be automatically controlled electronically was revolutionary in that it expanded the customer base for eye reflex cameras, and the demand for such automatically controlled cameras continues to grow. It is considered that

Incidentally, this type of automatic electronically controlled camera is required to be equipped with many functions in order to respond to an expanding customer base. That is, the camera must be capable of satisfying the needs of everyone from experts to beginners.

In this way, automatic electronic control of cameras is highly required to be multi-functional in order to meet various needs, but on the other hand, operations to select individual functions are complicated, and operations using automatic electronic control are required. Generally, there is a problem that the biggest advantage of facilitating the process may be lost.

From this point of view, a ROM (code) board can be installed in the camera, and by installing this ROM board in the camera, * Determination of the exposure mode * Determination of the need for viewfinder display * Determination of the necessity of displaying the viewfinder * When the number of film sheets is running low A camera has been proposed that selectively specifies a specific function that suits the user's needs from among the many functions that the camera has, such as determining whether or not a warning is necessary (Japanese Patent Laid-Open No. 107-1989).
(See Publication No. 339).

This method is intended to simplify and facilitate operations by selectively specifying many functions of the camera by attaching a ROM board to the camera.

However, the above method of pre-preserving all expected functions and having users select a specific function from among them is, in a sense, very appealing to some users; However, having to select or specify individual functions is a major burden on the user.

On the other hand, data related to camera functions is stored in advance in a ROM or FROM means provided separately from the camera body.
A camera has been proposed in which, by connecting such an external storage means to the camera body, a program diagram for exposure control can be set on the camera side, or it can be determined whether or not to activate a camera function. Japanese Patent Publication No. 58-1265
(See Japanese Patent Application Laid-Open No. 107339/1982).

In this case, these external storage means can reduce the amount of data that must be stored in the camera in advance, but in this type of system, when the external storage means is disconnected, Control of the function on the camera side is also disabled. For this reason, it is necessary to carry such external storage means with the camera at all times.
If there is no external storage means, there is a risk that the camera itself cannot be operated.

[Object of the Invention] The present invention has been made in view of the above-mentioned problems of conventional multi-functionalization, and provides a system that allows functions to be added or changed in response to various needs of users. Our basic objective is to provide a camera that can accurately respond to the needs of individual users. It is an object of the present invention to provide a camera system capable of storing data regarding functions performed.

[Structure of the Invention] Therefore, the present invention provides a camera that can be equipped with an IC card that stores data related to camera functions in advance, and includes a detection means for detecting whether or not the IC card is installed; a reading means for reading data stored in the IC card into a storage means of the camera when the IC card is inserted;
The present invention provides a camera using an IC card, characterized in that it is provided with a control means for specifying a function of the camera to be executed according to data read into a storage means regardless of whether or not a C card is installed.

In the present invention, once the IC card is attached to the camera body, the data stored in the IC card is read into the storage means within the camera body, and the functions of the camera are specified according to the contents of the stored data. It becomes possible to execute the relevant function.

[Hereinafter, in the margins], [Examples] Hereinafter, embodiments of the present invention will be specifically described with reference to the accompanying drawings.

Disable all interrupts to l- and reset all flags and output ports in RAM (step #5. #IO
). Next, proceed to the card judgment/reading routine (#
I5). In addition, this subroutine is performed when inserting/removing the card and when taking pictures! lI/(equipment switch (Sl) is O
It is also executed when the result is N.

To explain this subroutine according to the flowchart shown in Figure 1, the microcomputer (μC) first
Set it to “0” #45), terminal (C, 5CAD) (4th
(see figure) is set to high level, and serial communication is performed with the IC card (CD). Enter byte data (#
50. #55). This serial communication will be explained with reference to FIG. 4. When the terminal (C8CAD) becomes high level, the AND circuit (ANI) and (ΔN2) become active. The microcomputer (μC) then outputs eight pulses from the terminal (SCK), and these pulses are sent to the AND circuit (A
terminal (SCK) of the IC card (CI)
) is entered. In response, the IC card (CD) outputs a 1-bit signal from the terminal (Sout) in synchronization with the rising edge of the pulse. The microcomputer (μC) receives the signal output via the AND circuit (AN2) and the OR circuit (Ort3) in synchronization with the falling edge of the pulse.

Do this 8 times to complete one serial communication.

The contents of this human power data are shown in Table 1. Table 1 = 11
- The presence or absence of a card and the type of card are determined using 2 bits (bl, bO).

Table 1 (bl, bO) - (0, 0) is when there is no signal (when no card is inserted), and [C card (CI)
) is not inserted. (b I , bO)
= (0, 1) indicates that the inserted IC card (CD) is a mode setting change card, (blJO) =
(1,0) indicates that the inserted IC card (CI)) is an exposure program card, and (bl,l>0

Returning to F [J-] in Figure 1, the microcomputer (μC) determines whether or not an IC card (CI) is installed in the camera based on the above input data.4 (IO) indicates that no card is installed. If so, set the terminal (C8CAD) to low level to indicate the end of data communication (#65), and then use the battery flag (13Δ′1゛1ma) to determine whether the battery is installed (#75). ). At the time of battery installation q11, this flag (BΔT17) is set, so

Since this flag is written in the E" P I't OM, once it is written, it will not be reset even if the battery is removed or installed.

If the mode setting enable flag (WEI) F) is set, a mode whose settings can be changed is displayed and the process returns (#l05). If not set, step #1
Skip 05 and return.

This mode display and mode setting switch (see FIG. 2) will now be explained with reference to FIG. 6. As shown in FIG. 6, the switch unit 2 formed of liquid crystal is a part where a total of four displays indicating four mode setting switches (2-1 to 2-4) are displayed within the outer frame. Yes, it will be displayed once a change card is inserted, and will continue to be displayed even if the card is removed. If a setting change card is never inserted, no display is performed. In addition, the bipedal display device (2) is the fourth
It corresponds to the second display device (DISP2) shown in the figure, and has switches for changing modes.By lightly pressing the four saw parts with a small square, you can set the mode of the pressed part. , or the mode can be changed.

Returning again to the flowchart in FIG. Step #60
When it is determined that the IC card (CD) is inserted, the microcomputer (μC) confirms that the IC card (CD) has been inserted! The type of 0 card is determined from the data manually generated in step #55.

If it is a setting change card (#ll0), step #1
Proceed to step 15. In step #115, the mode settable flag (WEI) is read from the I-C'[' It OM. Do it like this.

Write to M and proceed to step #95 (#l35). If the inserted IC card is an exposure program card, the process proceeds from step #140 to #150 and serial communication is performed. Then, add 1 to N (#155) and determine whether N is 2 (#160). If it is 2, the terminal (
C8CAD) is set to low level, and the 2-byte data communication is ended (#l65). If N is not 2, the process returns to step #150 to continue serial communication. The 2-byte data content read from the exposed program card by serial communication is 11 bits, which indicates the number of bytes (approximately 21) required to write the data.
The 5 bits specify the types (32 types) of the 11 grams. Although only two types of exposure programs are used in the example, it is possible to add various other exposure programs.
When the 2-byte data communication is completed, the program load flag (1, ) WF) indicating whether the contents stored in the IC card have been loaded into RΔMP is determined (step #I 75), and whether it is set or not. If not, proceed to step #180, set N=0, and perform serial communication to read the contents of the exposure program (#l85).
). Then, for each data communication, 1 is added to N (#190), and N is 0 (ha); step #I50.
Data exchange is performed until the number of bytes reached (# I 60) is reached (# I 95), and when it reaches K, an exposed block ``Block indicating that the contents of the Noblam card have been loaded'' is displayed. Set the 1 gram load flag (+)Wl?) (#205) and proceed to step #I+7.
The data of the exposure program camera 11 read from the 0 card is sequentially loaded into the RAM of the microcomputer (μ0).

Proceed to 00, determine whether the mode settable flag (WFCDF) is set, and if it is not set, display the settable mode (#l05).

In this embodiment, the mode setting change card allows settings to be changed for four modes, and when the - degree is inserted on this card, the display shown in FIG. However, one mode setting change card is one card.
It may be possible to change only one mode or to change two or three modes. Modified examples of the data reading and display control flow at this time are shown in FIGS. 7 and 8.

FIG. 7 shows a modification of steps #115 to #I35 in FIG. 1.

Serial communication (S'IO) is performed (#I25), and the terminal (C8CΔ1) is set to low level to end data communication (#130). Next, the type of setting change card is determined from the data input through serial data communication (# I 31''), and the corresponding E21) is written to the bit specified by the predetermined address in the ROM (# I 31'').

In the embodiment shown in Fig. 31, the display of setting modes whose settings cannot be changed is flashed to warn you, but in Fig. 32, this warning is not given, and only the modes that can be set are displayed cyclically. Each time the camera is operated, the photographer is made aware of the modes that cannot be set, and is also able to quickly shift to the mode in which the settings are desired to be changed. Specifically, as is clear from a comparison with FIG. 31, the flag determination step number indicating that the settings can be changed is entered before proceeding to each setting mode (#l332.#l357, #l357, #l357,
1377, #1392), when the flag is set, the process proceeds to the mode for each setting, and when it is not set, the process proceeds to the first step for determining whether to set or change the next mode. In other words, if step #1332 determines whether or not to change the E setting mode, from step #1332 to step #1335,
If the determination step # I 357 is whether to perform the O setting, the process goes from step #+357 to #1360. If the determination step #1377 is whether to change the exposure compensation, the process goes from step #1377 to #1390. , if it is determination step #l392 whether or not to change the drive mode, the process proceeds from #l392 to #l310.

In the above embodiment, the IC card was placed on the side of the camera body, but if there is no space, it may also be placed on the back of the camera. Manoko, as an IC card that can be set to change functions, 0 program shift l-1 function card 0 highlight /
Shadow function is possible Card 0 One-shot Δ1・゛ For models with only one shot, Continuous ΔF function can be switched. Card 0 For cameras with ΔF function, Δ1・゛ priority and release priority can be switched. Card 0 Self function can be switched. If the camera has one, a card that can self-switch the time (for example, 2 seconds, 10 seconds, 15 seconds) can be considered.

[Hereinafter, blank spaces] [Effects of the Invention] According to the present invention, the functions of the camera are maintained even when the IC card is not attached to the camera body and even when the functions of the camera are not maintained. , the camera can be operated even if the IC card is lost or not carried with the user.
