Abstract

PURPOSE:To improve operability by holding the mode of one operation switch in a switch box which is low in frequency of use until any other operation switch is operated when the former switch is operated. CONSTITUTION:An automatic bracket switch (swABR) or multiple photographic switch (swME) which is relatively low in frequency of use is stored in a storage part 7 on the reverse surface side of a camera. When the switch cover 6 of the storage part 7 is opened and the swABR is pressed, an automatic bracket mode is set and held thereafter, but when the swME is pressed, a multiple photographic mode is set and held. Then the number of exposure stages or the number of times of multiple photography required for photography in those mode is set with a dial 5. Either mode is reset by pressing another other switch in the storage part 7 or by a 1st stroke of a release button, so a switch and the dial need not be operated at the same time and the operability is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Application of the Invention) The present invention provides a storage for storing switches for setting modes that are rarely used, such as switches that allow setting of information required when shooting in auto bracketing mode, for example. This invention relates to an improvement of a camera equipped with a camera.

Note that the auto bracketing (more precisely called auto exposure bracketing) refers to the camera's exposure value (in the case of automatic exposure, the exposure control value is automatically calculated from the subject brightness and film sensitivity, and in the case of manual exposure, This refers to the offset of the camera with respect to the shutter speed or aperture value set by the photographer.Simply put, when photographing a certain subject, multiple photos are taken by changing the exposure value in several stages. This means that the camera automatically takes pictures.

(Background of the Invention) For example, as camera specifications such as auto bracket mode increase, the number of operation members such as operation buttons and operation levers on the outside of the camera increases. Because there are so many operating members, there is a high probability that the photographer will operate them carelessly.

This also caused many problems in terms of external design. Also, for example, when setting the information necessary for shooting in a certain mode, it is difficult to hold the camera while holding down one control button with one hand while moving a dial with the other. The photographer was responsible for the operations.

Therefore, in view of the former point, in recent years, 2,000-type camera switches that are used less frequently have been housed in a switch box formed on the back side of the camera. This eliminates the risk of the photographer inadvertently operating the camera, and is also effective in terms of external design. However, regarding the latter point, the above-mentioned problem was clearly evident. That is, it was extremely difficult to move the dial while operating the small switch inside the switch box.

(Objective of the Invention) The object of the present invention is to solve the above-mentioned problems, and to improve operability while preventing damage to external design and careless mode setting. The goal is to provide cameras that can.

(Features of the Invention) In order to achieve the above object, the present invention stores information input from a setting input means in a state where the operation means is stored in the storage means, as information corresponding to the stored operation means. When the operating means is set and the operating means is not stored in the storage means, the information setting means does not set the information input from the setting input means, and the information setting means does not set the information to be input from the setting input means, and the information setting means does not set the information input from the setting input means, and the information setting means does not set the information input from the setting input means, and the information setting means does not set the information inputted from the setting input means, and the information setting means does not set the information inputted from the setting input means. and a release means for erasing the memory of the operating means in the storage means in response to the operation of the operating means, so that even if the operation of the operating means in the storage unit is stopped, the operating means of the function is not operated. The present invention is characterized in that the information setting enabled state generated by one operation in the storage unit is maintained until the information setting means is set.

(Embodiment of the Invention) FIG. 1 shows the basic configuration of an embodiment of the invention, and FIG. 2 shows its flowchart.

For example, a first operating means 103 and a second operating means for setting a certain mode are provided in the storage section 102 which is used relatively infrequently.
The first and second operating means 104 can be operated only by opening the storage lid 101. The setting input means 105 is used to input settings for a plurality of types of information, and the storage means 1
06 is for storing when the first operating means 103 or the second operating means 104 in the storage section 102 is operated. The information setting means 107 sets the information set by the setting input means 104 as information corresponding to the operating means stored in the storage means 108. Further, swl is a switch that is turned on by the first stroke of the release button, and is a release means 1.
09, for example, the first operation means 102 is stored in the storage means 106.
When it is detected that the second operation means 104 or the switch swl is turned on when the operation 106 is stored, the contents stored in the storage means 106 are erased.

When the first stroke of the release button has not been made,
When the first operation means 103 is operated, the storage means 1
06 stores that the first operation means 103 has been operated. Therefore, the information setting means 107 inputs the information input from the setting input means 105 at this time to the first operation means 10.
Read and set the information corresponding to mode 3.

Further, when the operation of the first operation means 103 is stored in the storage means 106 and the information corresponding to the first operation means 103 is set, when the second operation means 104 is operated, The memory of the operation of the first operating means 103 in the memory means 106 is cleared by the release means 109, and the memory of the operation of the first operating means 103 is now stored in the memory means 106.
The fact that the operation was performed is remembered. Therefore, in this case, the information setting means 107 reads and sets the information input from the setting input means 105 as information corresponding to the mode of the second operating means 104. Further, even when the first stroke of the release button is performed and the switch swl is turned on, the content stored in the storage means 106 by the release means 109 (that the first operation means 103 has been operated) memory) will be canceled.

Fig. 6 shows the arrangement of each operating member when viewed from the back side. In Figs. 4 to 6, 1 is the release button, and 2 is either the quick copy (C) or the leather copy (S). Operation lever for selecting one of the shooting modes, 3 is the operation lever for selecting the self-timer, 4
5 is the exposure mode selection knob that selects shutter priority (Tv), aperture priority (Ay), or manual (M) exposure mode, and 5 is the shutter speed, aperture value, or exposure step number information for auto bracket shooting ( SWM is a so-called electronic dial with a brush and a 2-bit conductive pattern with a phase difference of 90 degrees that is used to set the aperture value (for example, information for each 0.5 step or 1 step). The aperture value can be changed by pressing the switch swM and operating the dial 5 in the manual exposure mode. Reference numeral 6 indicates a switch lid of a storage section 7 that stores switches that are used less frequently, 5WABR indicates an auto bracket switch that is stored in the storage section 7, and swME indicates a multiplex shooting switch that is also stored in the storage section 7.

For example, the information converted into actual aperture information is output to a stepping motor or the like, and this is driven to perform appropriate aperture control.

Next, the operation of the microcomputer COM will be explained with reference to flowcharts shown in FIGS. 7-9.

When the battery BAT is loaded into the camera and the power supply Vbat is generated, the microcomputer COM starts the operation from the start of the flowchart shown in FIG.

[Step l] Suppose that the photographer only makes the first stroke of the release button l, and the first stroke switch s
When the wl ON signal is input to the input PAO, the process proceeds to step 2.

[Step 2] Output a 1" signal from the output capo PF, turn on the transistor TRbat, and supply power Vcc to each part. Next, start the photometry timer. The photometry timer is activated when the first stroke switch swl is turned off. This is to keep the power supply Vcc continuously supplied for a predetermined period of time after signal input.This allows the photographer to check the metering status for a predetermined period of time even if he or she takes his hand off the release button L, which is displayed using the exposure mode selection knob 4. It becomes possible to change the setting information while looking at the screen.This configuration can be easily performed using a hardware timer built into the microcomputer COM.

[Step 3] The photometric information Ev converted into a 4-bit digital value by the A/D converter ADC is stored in the internal register RGEv.

[Step 4] It is determined whether the shutter priority mode is set based on the input states of the input ports PPO and PP1. If the shutter priority mode is currently set, the process proceeds to step 5.

[Step 5] From the contents of register RGEv.

The contents of the shutter information register RGTv, which stores the information set by operating the dial 5, are subtracted, and the result (aperture information Ay) is stored in the aperture information register RGAv.
to be memorized. It is assumed that the contents of all registers in the microcomputer C0M are held while the battery BAT is loaded. Further, when the battery BAT is loaded for the first time, it is assumed that a frequently used value, for example, information such as 1/125 seconds is initially set.

[Step 6] The contents of the register RGBH storing the auto bracketing exposure step number information are stored in the aperture bracketing step number register RGBA. Also, the contents of the shutter bracket stage number register RGBT are set to zero (0).

[Step 7] - Determine the state of flag FABR indicating whether auto bracketing mode is set.

Assuming that auto bracketing mode is not currently set, proceed to step 8.

[Step 8] Determine the state of flag FMH indicating whether multiple shooting mode is set.

Assuming that the multiple shooting mode is not currently set, the process advances to step 9.

[Step 9] Auto bracket switch 5WAB
A flag FsAB indicating whether R has been operated is reset to 0. Also, a flag FsME indicating whether the multiplex photographing switch swME has been operated is reset to 0.

[Step 103: The contents of the aperture information register RGAv are output from PFD, and the contents of the shutter information register RGTv are output from PTD. As a result, the aperture value calculated by the calculation is displayed on the display 5EG5, and the set shutter speed time is displayed on the display 5EG1.

[Step 11] The second stroke of the release button 1 is performed, and the on signal of the second stroke switch SW2 is input, which determines whether the on signal of the second stroke switch SW2 is input to the input port PA1. If not, return to the start. Also, while the ON signal of the first stroke switch 5W1 is being input, subject brightness information, film sensitivity information,
Calculation information can be obtained from the setting information and this information can be displayed.

Further, if the aperture priority mode is set, the process proceeds from step 4 to step 12 to step 13.

[Step 13] Subtract the contents of the register RGAv, which stores the information set by the operation of the dial 5 and the aperture value setting switch swM, from the contents of the register RGEv, and add the result to the shutter information register RGT.
Store it in v.

Note that when the battery BAT is loaded for the first time, a frequently used value 1, for example, F5.6, is initially set.

[Step 14] The contents of the bracket stage number register RGBR, which stores the exposure stage number information of auto bracketing, are stored in the shutter bracket stage number register RGBT. Also, the contents of the register RGBA for the number of aperture rebracketing stages are set to zero.

Thereafter, in the aperture priority mode, the same sequence as in the shutter priority mode is performed, and the aperture value set in step 10 is displayed on the display 5EG5, and the shutter speed calculated by the calculation is displayed on the display 5EG1. Is displayed.

If the manual exposure mode is set, the process goes from step 4 to step 12 to step 15.

[Step 15] Register RGTM that stores the shutter speed information set by operating the dial 5
The contents of are stored in the shutter information register RGTv. This is because when auto-bracketing shooting is set in manual exposure mode, the contents of register RGTv change each time a shot is taken, so the information set by operating dial 5 is stored as is. Details will be explained later. do.

After that, the same sequence as in the aperture priority mode is followed, and the aperture value set in step 10 is displayed on the display 5EG5.
The set shirt time is displayed on the display 5EGI.

Next, we will describe information setting by dial operation while the photometry timer is operating. When the pressing of the release button 1 (first stroke) is stopped during the above-described sequence, the off signal of the first stroke switch swl is input, and the program proceeds from step 1 to step 20.

[Step 20] It is determined whether the switch lid 6 has been opened or not based on the state of the switch 5w5ET. If the switch cover 6 remains closed, the input capo) PA9
Since the off signal of the switch 5w5ET is input to the step 21, the process advances to step 21.

[Step 21] It is determined whether or not the photometry timer is in operation. Here, since the photometry timer has been activated in step 2, the process advances to step 22.

[Step 22] It is determined whether the shutter priority mode is set based on the input states of the input ports ppo and ppt. If the shutter priority mode is currently set, the process proceeds to step 23.

[Step 23] Here, an information reading routine associated with the operation of the dial 5 is executed. Here, the information reading routine accompanying the dial operation will be explained with reference to FIG.

"Information Reading Routine" [Step 80] The information input to the input ports PH0 to PH3 is stored in the dial register RGH. At this time, the register RGH stores a numerical value corresponding to the number of clicks on the dial 5 and information as to whether the numerical value is positive or negative depending on the direction of rotation of the dial 5. That is, 4-bit information indicating how many steps to shift up or down from the current information is stored.

[Step 81] Output the pulse signal of PE3. As a result, the dial interface circuit D
The value of IF is reset to zero.

[Step 82] Return to the original step.

Returning again to the flowchart in FIG.

[Step 24] The numerical value set by the dial operation (the contents of register RGH) and the shutter information (the contents of register R
(contents of GTv) and stored in the shutter information register RGTv again.

Also, the contents of the shutter information register RGTv are stored in register R.
Store it in GTM.

[Step 25] It is determined whether or not a certain code indicating the valve mode located next to the longest second of the shutter speed is stored in the register RGTM.If it is not currently the valve mode, go to NEXTl, that is, step 3 jump.

In this way, during the photometry timer after the press of the release button 1 (first stroke) is stopped, the setting information can be changed by operating the dial 5, and then the routine from step 3 described above is executed. In step 10, the aperture value and shutter speed are displayed on the display 5EGI.
5EG5, respectively.

Further, if the aperture priority mode is set, the process proceeds to step 22 -> step 26 -> step 27.

[Step 27] Similar to step 23, here, an information reading routine associated with the operation of the dial 5 is executed.

[Step 28] The numerical value set by dial operation (contents of register RGH) and aperture value information (contents of register RG
Av contents) and register RG for aperture information again.
Store it in Av. Also, in aperture priority mode, NEX
The aperture value and the shutter speed can be displayed on the display SEG 1.5EG5 in step 10, as in the case of the shutter speed priority mode.

If the manual exposure mode is set, the process proceeds from step 22 to step 26 to step 29.

[Step 29] Determine the on/off state of the aperture value setting switch swM. In the manual exposure mode, operate the aperture value setting switch swM and operate the dial to set the aperture value, and only by dialing the shirt button. Since the configuration is such that the seconds and hours can be changed, when the switch 5WM is on, the routine proceeds to the same routine (step 27) as in the aperture priority mode, and when it is off, the shutter priority mode is executed. The program then proceeds to execute the same routine (step 23).

When a predetermined period of time has elapsed after the pressing operation of the release button 1 was stopped, the photometry timer operation ends.

Along with this, the program moves from step 21 to step 3.
Proceed to 0.

[Step 30] Output ports PTD, PFL.

The outputs of PABR, PME, and PFD are set to "0", and all displays on the displays 5EG1 to 5EG5 (however, the display 5EG2 is not present) are turned off. Also, the output of the output capacitor) PF is set to "0", the transistor TRbat is turned off, and the supply of the power supply Vcc is stopped.

[Step 31] Similar to step 9, both the flag FsAB indicating whether the auto bracket switch swABR has been operated and the flag FsME indicating whether the multiple shooting switch SWME has been operated are reset to 0.

The program then jumps to the start.

Therefore, after the photometry timer ends, step 1→step 2
The standby mode of 0→Step 21→Step 30→Step 31 is repeated.

Next, a description will be given of the time when the auto bracketing mode is set. First, a case will be described in which only the opening operation of the switch cover 6 is performed to set the auto bracketing mode. When switch M6 is opened, switch 5w5 is opened in conjunction with it.
ET is turned on, and this on signal is input to input capo PA9. The program then proceeds from step 20 to step 40.

[Step 40] Auto bracket switch SwAB
Since the switch cover 6 has just been opened and the auto bracket switch 5WABR has not been operated, the process proceeds to step 41.

[Step 413: Determine whether the multiplex photography switch SWME is active. Similarly, since the multiplex photography switch swME has not been operated, the process proceeds to step 42.

[Step 42] Flag FsME indicating whether or not the suppression operation of the multiplex shooting switch 5 wME has been performed.
In the initial loading state of the battery BAT and the ON state of the first stroke switch swl, in which the determination is made, the flag FsME has been reset to O in step 9, so the process advances to step 43.

[Step 43] Auto bracket switch SwA
Flag FsAB indicating whether or not a BR pressing operation has been performed
As in the case of step 42, step 9
Since the flag FsME is reset to 0,
Step 2 Eheji Jump.

If the switch cover 6 is opened in this way and only the ON signal of the switch 5WSET is input, nothing is executed.

Next, from the above state, auto bracket switch swAB
A case will be described in which the pressing operation of R is performed once. When the auto bracketing switch swABR is pressed, an on signal is input to the input capo (PAII). The program then proceeds from step 40 to step 44.

[Step 44] It is determined whether the contents of the register RGTM are in the valve mode. If the contents are in the valve mode, the process returns to the start and the auto bracketing mode is not entered.

If the valve mode is not set, proceed to step 45.

[Step 45] Auto bracket switch SwA
A flag FsAB indicating that the BR is turned on is set to l, and a flag FsME indicating that the multiplex photographing switch swME is on is reset to zero.

[Step 46] Output port PTD, PFL.

Set the output of PABR, PME, and PFD to “O11.”

All the displays on the displays 5EGI-3EG5 are turned off. Only the output of the primary output capo (PABH) is set to "1", and the auto bracket mark on the display 5EG3 is lit. This allows the photographer to clearly know that the auto bracketing mode has been set.

[Step 47] A flag FABR indicating that the auto bracketing mode has been set is set to 1.

[Step 48] Similar to step 23 or step 27, an information reading routine associated with the operation of the dial 5 is executed. In this case, in step 80, if the stage number information is set to 0.5 using the dial 5, for example, the stage number is r-0,5,0°0.5, and if l is set.

The exposure was automatically changed by the number of steps of r-1, 0, IJ,
Three preset auto bracket shots will be taken. In addition, the above “−〇.

Shooting with 5.0 and 0.5J steps means an exposure value that is -0.5 steps under the standard exposure value calculated by calculation, a standard exposure value, and 0 to the standard exposure value. .5
This means that photography is performed continuously using three levels of exposure values, including exposure values that are one step over.

[Step 49] Blanket stage number register RGB
Add the contents of H and the contents of the dial, and register RG again.
Store it in BH. As mentioned above, the minimum resolution by one click of the dial 5 can be set freely in increments of 0.5 steps or in increments of 1 step. Note that if the resolution is different from the shutter speed and the aperture value, it is sufficient to insert a program that multiplies the contents of the register RGBH by an integer, and since this is not relevant to the present invention, a detailed explanation will be omitted here. Further, the contents of the register RGBH are outputted from the output port PFD, and numerical values indicating the number of stages, such as ro and 5J, are displayed on the display 5EG5. The decoder FD and display 5EG5 used at this time are also used to display the aperture, and the aperture value is decoded from the apex value Ay to the F number number, and the auto bracket is decoded from, for example, 0.5. Since it is a numerical value for each stage, it is necessary to change the decoded contents.

For example, if the output from the output port PFD is 5 bits, 32 types of data can be sent, so if the aperture value display is Fl, 4 to F32, every 0.5 stop, there are 14 types in total, and auto bracketing. If the display is from 0 to 5 in 0.5 step increments, there are 11 types in total, 30 types in total, and 31 types including blank codes.By adding a certain constant when sending data to the output capo-PFD Decoder F
It is possible to determine which information D is.

Appropriate numerical display becomes possible.

[Snap 50] A flag FMH indicating whether the multiple shooting mode is set is determined. If the multiple shooting mode is not set, the process returns to the start. If the mode is multiple shooting mode, the process advances to step 51.

rStep 51] Set the contents of the register RGMH for the number of multiple shots to "3". This is because the number of auto bracket shots is predetermined to be three, so even if the number of times for multiple shots is set arbitrarily, it is mandatory. The program returns to the start in order to prevent the photographer from making operational mistakes and to eliminate the risk of erroneous exposure. Furthermore, once the switch swABR on signal is input, the flag FsAB is set to 1 in step 45, so even if the swABR off signal is input, the program continues from step 40 → step 41 → step 42. → Step 43 → Step 48, and the mode for changing the number of auto bracketing stages can be maintained using dial 5, and the photographer can operate dial 5 while stopping the pressing operation of switch 5WABR. .

The auto bracket stage number changing mode can be canceled by turning on the first stroke switch swl, or by closing switch M6 and turning off switch 5w5ET. In other words, when the ON signal of the first stroph switch Swl is input, the program progresses in the order of step 1 → step 2 → step 3 →..., and in step 9, the flag FsAB is reset to 0, and its display The display is also switched to the normal display in step 10. Also switch 5w5ET
When the off signal is input, step 20. Step 2
In the process of the program proceeding from step 1 to step 30 to step 31, the auto bracket mark display disappears at step 30, and the step 31 flag FsAB is reset, so that the program does not proceed to the auto bracket stage number change mode again.

Next, exposure calculation in auto bracketing mode will be explained. In the case of shutter priority mode, the contents of the bracket stage number register RGBH are stored in the aperture bracket stage number register RGBA as described in step 6, and in the case of shutter priority mode and manual exposure mode, the contents of the bracket stage number register RGBH are stored in step 14.
As mentioned above, the shutter bracket stage number register RGB
T memorizes each. In step 7, since the auto bracketing mode is set and the flag FABR is set to 1, the process advances to step 52.

[Step 52] Bracket stage number register RGBH
Determine whether the content is military or not. If the content is zero, then 3 with the same exposure (standard exposure in the example)
Since multiple shots are taken, it is meaningless, so it is necessary to prohibit auto bracket shooting. Therefore, in this case, the process advances to step 53.

[Step 53] A flag FABR indicating auto bracketing mode is reset to 0. Also output port PABR
Set the output to “0” and turn off the auto bracket mark display.

Next, by proceeding to step 8, the auto-bracketing exposure calculation is not performed, the flag FsAB is reset to 0, and a normal routine is executed.

In step 52, if the contents of the bracket stage number register RGBH are not zero, it is necessary to perform exposure calculation and display of the auto bracket mark using the stage number information, so the process proceeds to step 754.

[Step 54] Set the output of PABR to “°
l"' and display the auto bracket mark. This is done when the switch cover 6
This is because when the switch 5w5ET is turned off by closing, the display is all turned off in step 30, so if the first stroke switch swl is turned on, it is necessary to turn it on again.

[Step 55] It is determined whether or not the first stroke switch SWl is turned on. If it is turned on, the process advances to step 56.

[Step 56] The contents of the aperture information register RGAv and the contents of the aperture bracket stage number register RGBA are added and stored in the register RGAV again. Also, the contents of the shutter information register RGTv and the contents of the shutter bracket stage number register RGBT are added, and the register R is added again.
Store it in GTv. This means that the aperture information calculated in the shutter priority mode and the shutter speed information calculated in the aperture priority mode are changed in accordance with the number of autobracket stages. In other words, if the autobracketing step number is set so as not to be a negative number at step 49, the value after the calculation at step 56 will be an exposure value on the under side of the standard exposure value. In addition, in manual exposure mode, since step 14, which is the same as in aperture priority mode, is passed, the shutter speed is changed, and the aperture value is not changed as in conventional cameras, so only exposure with a constant depth of field is used. Auto-bracketing photography is now possible.

Further, in step 55, the first stroke switch sw
If it is determined that L is off, the exposure calculation in step 56 is not performed because the photometry timer is operating.
In step 10, the standard exposure value will be displayed.

Even in this case, when taking a picture, the first stroke of the release button L is always made, so step 56 is always passed.
Therefore, there is no problem with auto bracketing photography.

In this way, in auto bracketing mode, if the first stroke switch swl is turned on, the exposure value with auto bracketing applied, that is, the underexposure value in this example, is displayed, and the metering timer is activated. The standard exposure value will be displayed inside. This allows the photographer to easily recognize the exposure value of auto bracketing.

Next, a case will be described in which the valve mode is set by operating the dial 5 after the auto bracket mode is set.

Bracketing during bulb photography is basically meaningless, so it is more effective to cancel auto bracketing mode. Therefore, if it is determined in step 25 that the mode is the valve mode, the process advances to step 57.

[Step 57] Set the output of PABR to “O1”.
1 to turn off the auto bracket mark display. Also, reset the auto bracket mode flag FABR to 0.

Next, a description will be given of when the multiple shooting mode is set.

The switch swM is activated in conjunction with the opening of the switch lid 6.
When the ON signal of E is input, the process proceeds from step 41 to step 60.

[Step 60] A flag FsME indicating that the multiplex photographing switch swME is turned on is set to 1. Also, a flag FsAB indicating that the auto bracket switch swABR is turned on is reset to 0.

[Step 61] Output port PTD, PFL.

Set the outputs of PABR, PME, and PFD to O" and turn off all displays. Set the output of PME only to l ss, and set the multiple shooting mode mark to display 5EG4.
to be displayed.

[Step 62] Flag FME indicating multiple shooting mode
Set to 1.

[Step 63] It is determined whether the mode is auto bracketing mode or not. If it is auto bracketing mode, the process proceeds to step 64.

[Step 64] Since the mode is auto bracketing, the number of multiple shots is forcibly set to three, as in step 51, that is, the contents of the register RGMH for the number of multiple shots are set to "
3".

If the auto bracketing mode is not set in step 63, the process advances to step 65.

[Step 65] Similar to step 48 and the like, an information reading routine associated with dial operation is executed.

[Step 66] Add the contents of the multiplexing number register RGME and the contents of the dial register RGH, and store the result in the register RGMH again. Since the number of times of multiplexing is an integer, if the resolution of one click of the dial 5 is 0.5 steps, the contents of the dial register RGH are doubled and then added. It is also necessary to prevent the contents of the register RGH from becoming a negative number, but this is omitted here.

[Step 67] The contents of the multiple-sheet same-circle register ROMH are output from the output capo PFD and displayed on the display 5EH5.

The program then returns to the start. Furthermore, once the ON signal of the switch swME is input, the flag FsME is set to 1 in step 60, so even if the OFF signal of the switch swME is input thereafter, the flag FsME is set to 1 in step 60.
1→Step 42→Step 63, and it becomes possible to maintain the multiple shooting number setting mode. The flow in Figure 7 shows that to shift from the auto bracketing step number change mode to the multiplex shooting setting mode, you only need to turn on the switch swME once, and to switch vice versa, you only need to turn on the switch swABR once. It is also clear from

Next, if the number of times of multiplexing is set once and then the number of times of multiplexing is set to zero (0), it is necessary to cancel the multiplex photography mode and turn off the multiplex photography mark. Since the flag FME is set to 1 in step 8, this program is executed by proceeding to step 68.

[Step 68] If the contents of the register RGMH for the number of multiple shots are negative, the process advances to step 69.

[Step 69] Flag FME indicating multiple shooting mode
Reset to O. Also, the output of output port PME is set to “0”.
' to turn off the multiplex shooting mark display.

If the contents of the register RGME for the number of times of multiple photographing are not zero in step 68, the process proceeds to step 70.

[Step 70] Set the PMH output to “°1”
The multiple shooting mark will be displayed. This is step 3
Since all the displays are turned off at 0, when the first stroke of the release button 1 is made again, the photographer is notified that the multiple shooting mode is in effect.

As described above, the preparation stage for photographing is completed.

Next, the sequence after the second stroke of the release button I will be described. When the second stroke of the release button 1 is performed and the on signal (release signal) of the second stroke switch sw2 is input to the input capo FAI, the process advances from step 11 in FIG. 7 to step 100 in FIG. 9. .

[Step 100] It is determined whether the auto bracketing mode is set or not based on the state of the flag FABR. If it is auto bracket mode, go to step 101.
Otherwise, proceed to step 102.

[Step 101] Output the output of PFL.
I II, and the auto bracket mark on the display 5EG2 flashes. This allows the photographer to reliably know that auto bracket photography has started.

[Step 102] Determine whether or not the ON signal of the self-switch 5ELF is input to the input port PA6. If the ON signal is input, the process goes to Step 103 because the photograph is taken using the self-timer. If not, the process goes to Step 103. Proceed to step 104.

[Step 103] A self-timer measures 10 seconds.

[Step 104J: Output the contents of the aperture information register RGAy from the output port PAv. As a result, the aperture control drive circuit DAV converts the contents of the register RGAv into actual aperture information, and starts aperture control via the aperture drive actuator CAV such as a stepping motor.

[Step 105] Output a pulse signal from output port PEO, turn on transistor TRO, and turn on MI'ig.
The mirror-up magnet MGO, which is a fixed combination magnet, is energized.

As a result, the mirror is raised by a known spring force.

[Step 106] It is determined whether or not the on signal of the switch swMRUP, which detects the completion of mirror up, is input to the input port PA2.Here, it is determined whether or not the on signal of the switch swMRUP, which detects the completion of mirror up, is input.Here, it is determined that the on signal is input until the on signal is input, that is, the mirror is completely raised. This loop is repeated until the image is completely uploaded, and the process proceeds to step 107.

[Step 107] Shutter information register RGTv
Since the content of is an apex value, it is converted (decompressed) into real-time data.

[Step 108] A pulse signal is output from the output capo PEI, the transistor TRI is turned on, and the shutter front curtain magnet MCI is energized. This causes the shutter front curtain to run.

[Step 109] It is determined whether the contents of the register RGTM indicate the valve mode.

If the valve mode is set, the process proceeds to step 110; otherwise, the process proceeds to step 111.

[Step 1101 Second stroke switch SW2
Since this is the valve mode, it is necessary to keep the shutter open while the on signal of the second stroke switch sw2 is input.

[Step 111] Since it is not the valve mode, a real time count is performed using the data expanded in step 107, and the calculated shutter time is measured.

[Step 112] When the real time count ends, a pulse signal is output from the output capacitor PE2, and the transistor TR2 is turned on to energize the shutter trailing curtain magnet MG2. This causes the shutter trailing curtain to run.

[Step 113] Determine whether or not the on signal of the shutter rear curtain switch 5wCN2 is input to the input capo PA5. Here, until the on signal is input, the running of the shutter rear curtain is completed. This loop is repeated until the process is completed, and upon completion, the process proceeds to step 114.

[Step 114] Set the output of output port PAv to “0”
This returns the aperture to its open state.

[Step 115] Set the output of the output port PD to °“1”
'', the transistor TR3 is turned on, and the charging motor MD for mirror down and shutter charging is rotated.

[Step 116] It is determined based on the state of flag FMH whether the multiple shooting mode is set. If it is the multiple shooting mode, the process proceeds to step 117; otherwise, the process proceeds to step 120.

[Step 117] Subtract 1 from the contents of the multiplexing number register RGME and store it in the register ROMH again.

[Step 118] It is determined whether the contents of the multiplexing number register RGME are zero. If the contents are zero, the process proceeds to step 119; if not, the process proceeds to step 121.

[Step 119] Since the content of the multiplexing number register RGME is 0, it means that multiplex photography has ended, so the flag FME indicating the multiplex photography mode is reset to 0. Also, set the PME output to "°0" and turn off the multiple shooting mark display.

[Step 120] Start a timer for film feeding. The output of output capo) PB is set to l'', transistor TR5 is turned on, and film feeding motor MB is rotated.

If the multiple shooting mode is continued, the contents of the multiplex number register BGMH are not zero, so the process advances from step 118 to step 121, and since step 120 is not passed, film feeding is not performed, so multiple shooting is not performed. It will be done. Furthermore, when multiple photography is completed, the contents of the register ROMH become zero, so film feeding is performed in step 120 after canceling the multiple photography mode as described above.

[Step 121] Determine whether or not the ON signal of the charging completion detection switch swCGE is input to the input capo PA3. If the ON signal is not input, that is, charging is not completed, step 123 The process proceeds to step 122, and when charging is completed, the process proceeds to step 122.

[Step 122] Since charging is completed, the output of the output port PD is set to "0'" and the charging motor MD is turned off.
Cut off the power to.

[Step 123] It is determined whether or not an on signal is input to the input port FA4 for the switch swFLM, which is turned on every time one frame of film has been fed. If not completed, proceed to step 124; if completed, proceed to step 1
Proceed to 25.

[Step 124] Determine the state of the film feeding timer. When the film is finished, no further film feeding is possible, so the switch swFLM is never turned on, and in such a case, the timer for film feeding, which is, for example, a one-second timer, finishes counting. When the time measurement is completed, proceed to step 150, otherwise proceed to step 1
21 and repeats the aforementioned sequence (step 121→step 123).

[Step 125] In step 123, switch s
When it is detected that the FLM off signal has been input, the output of the output port FB is set to "0", the transistor TR5 is turned off, and the film feeding motor MB is stopped.

[Step 126] It is determined whether the auto bracketing mode is set or not based on the state of the flag FABR. If it is not auto bracketing mode, step 132
If so, proceed to step 127.

[Step 1271 Determine whether or not auto bracket shooting has been performed three times.As mentioned above, auto bracket shooting is shooting that is performed continuously at three levels of exposure value: under, standard, and over. If the shooting is not completed, the process advances to step 128.

[Step 128] The contents of the aperture bracket step register GRBA are subtracted from the contents of the aperture information register RGAV, and the result is stored in the register RGAV again.

Also, the contents of the shutter bracket stage number register GRBT are subtracted from the contents of the shutter bracket stage information register RGTv, and the result is stored in the register RGTv again. Here the seventh
Similar to step 56 in the figure, the same program can be used for shutter priority, aperture priority, and manual exposure modes.
This is because the contents of T have been changed. It is clear from this arithmetic expression (subtraction formula) that the second shooting will result in standard exposure, and the third shooting will result in overexposure.

[Step 129] The contents of the registers RGAv and RGTv are output from output capo P, FD, and PTD, and the shutter speed information and aperture value information at this time are displayed.

Next, the program is NEXT2. That is, step 104 jumps to a higher position. In other words, regardless of whether or not the second stroke switch SW2 is on or off (regardless of whether a release signal is generated or not), the next photographing starts. Furthermore, even if the shooting at this time is in the self-mode, the next shooting starts without executing the 7-luff timer for the second and third times.

[Step 130] It is determined whether the off signal of the first stroke switch SW2 is input. If the off signal is not input at this time, step 128.
The display calculated in step 129 can be viewed.

In other words, the final overexposure value can be confirmed at this time. Therefore, since the first underexposure value can be seen in the discrimination display in step 55, all exposure displays of the underexposure value, standard value, and overexposure value during auto bracket shooting can be confirmed in the shooting sequence. becomes possible. When the off signal of the first stroke switch sw2 is input, the process proceeds to step 131.

[Step 131] A flag FABR indicating auto bracketing mode is reset to 0. Matade Capo) PF
Set the output of L to "0" and turn off the flashing display of the auto bracket mark.

The program then returns to start and enters standby mode.

Next, a case where the auto bracket mode is not set will be described. In this case, since the flag FABR is O, the process advances from step 126 to step 132.

[Step 132] Based on the on/off state of the switch swcs input to the input port PA7, it is determined whether the mode is a quick shooting mode or a single shooting mode.If it is a quick shooting mode, the process returns to the start, and in this case, the release button L is pressed. 1. Since the ON signal of the second stroke switch swl, 2 has been input, the next photographing begins. In the case of single shooting mode, the process advances to step 133.

[Step 133] Wait for the off signal of the first stroke switch SW2 to be input. Since this is single shooting mode, the next shooting sequence will not proceed unless the photographer stops pressing the release button L. The off signal is input. When is input, the process returns to the start.

Next, we will discuss the case where the film ends during shooting. In this case, as mentioned above, the time measurement by the film timer, which is a one-second timer, for example, ends, so step 12
4, proceed to step 150.

[Step 150] The output of the output port PC is set to 1'', the transistor TR5 is turned on, and the rewind motor MC is rotated. Thereby, rewinding of the film is started.

[Step 151] Start a rewind timer used to detect whether rewinding of the film has finished.

[Step 152] Film switch swFLM
If the state has changed, the process returns to step 151 and starts the rewind timer again. If there is no change, the process advances to step 153.

[Step 153] It is determined whether or not the time measurement by the rewind timer has ended. If it has not ended, the process returns to step 152.

As can be seen from the above, step 152. The process proceeds through the loop of step 153, and when the completion of feeding of one frame is detected, the process proceeds from step 152 to step 151, and this loop is repeated when the film is rewound. After that, when all the films are wound up in the cartridge, for example, the cartridge stops rotating and the state of the film switch 5wFLM no longer changes. If this is detected, the process proceeds to step 154.

[Step 154] The output of the output port PC is set to "O", the transistor TR5 is turned off, and the rewind motor MC is stopped. This completes the rewinding of the film.

[Step 155] A flag FABR indicating auto bracketing mode is reset to O. Also output port PF
Set the L output to “0” and turn off the flashing auto bracket mark.

The program then returns to the start.

Also, during auto bracket shooting, in other words,
If you have to take a series of shots, but the film runs out midway through, step 1 after the 1st or 2nd frame.
In such a case, auto bracketing should not be continued on the newly loaded film, as there is a risk that the subject may be different or the photographer may misunderstand. It is desirable to notify the photographer of this and cancel the auto bracketing mode at the same time. Looking at this in the flowchart of Figure 9, when the film ends after the auto bracketing mark is displayed blinking in step 101, Automatically moves to film rewind. While this film rewind is in progress, the flashing display of the auto bracket mark has not yet been canceled. Therefore, the auto bracket mark, which would not normally be displayed, is displayed during film rewind. The photographer can know that the film has ended without the auto bracket shooting being completely completed.

In other words, this is the warning display. Furthermore, since the flag FABR indicating the auto-bracketing mode is reset to O in step 155, the inconvenience of continuing auto-bracketing on newly loaded film as in conventional cameras is eliminated.

According to this embodiment, for example, when a signal indicating that the switch lid 6 is opened and an on signal of the auto bracket switch 5WABH are generated, the flag FsA is
Because B becomes “l”.

After that, even if you stop pressing the auto bracketing switch swABR, the sequence continues from step 40 to step 41 toge step 42 to step 43 to step 48, and in step 48, the exposure step number information necessary for shooting in this mode is set. Alternatively, the information can be changed, that is, information can be set simply by operating the dial 5, making it extremely easy to operate. Furthermore, since the information set in step 49 is displayed, the photographer can set the information while looking at the display, and can reliably know the information at the time.

Furthermore, the exposure step number information change mode and display can be canceled by the first stroke of the release button 1 or by multiple swings) 5W.
Since it can be performed in ME, it is possible to immediately move on to the next operation without having to cancel the mode each time, making it easy to use according to the photographer's will. .

(Effects of the Invention) As explained above, according to the present invention, when the operating means is stored in the storage means, information input from the setting input means is used as information corresponding to the stored operating means. When the operating means is set and the operating means is not stored in the storage means, the information setting means does not set the information input from the setting input means, and the information setting means does not set the information to be input from the setting input means, and the information setting means does not set the information input from the setting input means, and the information setting means does not set the information input from the setting input means, and the information setting means does not set the information inputted from the setting input means, and the information setting means does not set the information inputted from the setting input means. and a release means for erasing the memory of the operating means in the storage means in response to the operation of the operating means, so that even if the operation of the operating means in the storage section is stopped, the other operating means will not be operated. The state in which the information can be set due to a single operation inside the storage section is maintained until the information is set, and the information can be set by the information setting means during this time, so there is no risk of damaging the external design or inadvertently setting the information. This makes it possible to improve operability while preventing mode settings from being made inadvertently.
