Abstract

PURPOSE:To facilitate the resetting and displaying of mode by displaying a large number of modes on a liquid crystal display device and setting/displaying a prescribed mode at the position of an index when the resetting is executed. CONSTITUTION:For instance, when a photographer tries to select an S mode (shutter speed priority), a rotary operational member 5 is rotated clockwise by two clicks, so that the display of S appears at the position of the index 6 and the other modes are displayed in the same order as that before a change. When a rotational operation for changing the mode is executed, a mode display position is changed according to the rotational operation but the liquid crystal display device 4 itself is not rotated. Moreover, for the display of the mode, the liquid crystal display device 4 is used to attain program resetting. A reset button is operated to return to the prescribed mode, it is displayed at the position opposite to the index 6 and the other modes are displayed in the same order as that before the change.

Description of the Related Art In a conventional camera mode setting member, characters / symbols indicating an AE mode are printed on the upper surface of a rotary operation member, and an operation of operating the rotary operation member to select a mode to be aligned with an index position. Was going on. Since the rotation operation member is printed with characters and symbols indicating the mode, there is an advantage that it is possible to see at a glance how many modes there are and which operation should be performed.

Further, there is one in which the AE mode is selected by operating a dial or the like and only the selected mode is displayed on a liquid crystal display device on the body. Since this uses a liquid crystal display, what kind of setting is made? It is possible to reset all the settings and set / display in a predetermined mode (program mode or the like) simply by operating the reset button or the like once even if the operation is performed.

[0004]

However, the first one shown in the prior art has a drawback that it is difficult to reset and set a predetermined mode because the mode display is printed. . The second one is easy to reset and set to a predetermined mode, but it is difficult to understand what other modes are available because it displays only the selected mode. There is a drawback in that it is difficult to know in which direction and how much an operating member such as a dial should be operated to set the mode.

If functions such as a drive mode and a film speed setting mode are provided, the number of operating members will increase.

The present invention solves such a problem and allows a number of modes to be changed without increasing the number of operating members.
An object is to provide an operation member that can be easily reset and set or displayed in a predetermined mode.

[0007]

The operating member of the present invention comprises a changing means for changing a mode or a numerical value, a display means for electrically displaying the mode or a numerical value, and a mode or a mode displayed on the display means. Among the numerical values, the set mode or the index for indicating the numerical value, the display means is controlled to display the mode or the numerical value in a predetermined order, and the mode or the mode changed and set by the changing means is set. Indicates a numerical value at a position relative to the index, and display control means for controlling the display means so that other displays are displayed in the order before the change, and the mode or numerical value is reset to a predetermined mode or numerical value. Resetting means for setting and displaying.

[0008]

By doing so, a large number of the provided modes are displayed on the liquid crystal display device, and when the reset is performed, the predetermined mode is set and the predetermined mode is displayed at the position of the index.

[0009]

In the case of the example in FIG. 4, counterclockwise P (program), A (aperture priority), S (shutter speed priority),
Seven modes, M (manual), ISO value setting, drive, and exposure correction are displayed. For example, if the user is currently in the P mode as shown in (a) and tries to select the S mode, by rotating the rotary operation member 5 clockwise by two clicks, the index as shown in (b) is displayed. The display of S appears at the position of 6, and the display of other modes is displayed in the same order as before the change. When a rotation operation is performed to change the mode, the mode display position changes according to the rotation operation, but the liquid crystal display device 4 itself does not rotate. Further, all the characters and symbols of the mode display displayed on the liquid crystal display device 4 are displayed so as to face the same direction.

By using a liquid crystal display device for mode display, program reset (hereinafter, P reset) becomes possible. Regardless of which mode is selected, it is possible to return to a predetermined mode such as the P (program) mode by operating the P reset button 7, and as shown in FIG. The predetermined mode is displayed at the opposite position, and the other mode displays are displayed in the same order as before the change.

Next, the structure of the mode setting operation member will be described with reference to the side sectional view shown in FIG. Explaining the correspondence with the plan view of FIG. 4, 3
The main switch buttons 31 and 4 correspond to the display window 33 and the liquid crystal display unit 34 in the liquid crystal display device. The rotary operation member 5 corresponds to the dial 32. The main switch button 31 is arranged around the rotation axis x of the dial 32 and can be operated regardless of the rotation position of the dial 32. A protrusion 31a centering on the axis x extends from the lower surface of the main switch button 31, and the tip of the protrusion 31a contacts the main switch contact piece 45.
When the main switch button 31 is pushed down, the protrusion 31a pushes down the main switch contact piece 45, whereby the ON / OFF switching operation of the main switch is performed.

The liquid crystal display 34 is arranged inside the dial 32,
The display content can be viewed from above through the display window 33. The liquid crystal display unit 34 is a liquid crystal display device holding plate from the bottom.
It is held against the dial 32 by 35.
The dial 32 is held by a dial stopper plate 43,
Since the dial stop plate 43 and the dial 32 are integrally fixed by the stop plate retainer 44, and the cover member 36 is sandwiched between the dial 32 and the dial stop plate 43, the dial stop plate 43 and the dial 32 are rotatable. . A dial rotation detecting contact piece 42 is attached to the lower surface of the dial stop plate 43, and the rotation position of the dial 32 is brought into contact with the dial rotation detecting board 41 installed on the upper surface of the base member 37 disposed thereunder. Can be detected.

A click groove 38 is provided on the lower surface of the dial stopper plate 43. A click spring 40 is fitted in the base member 37, and a click ball 39 is held on a groove into which the click spring 40 is fitted. The click ball 39 is pressed against the dial stop plate 43 from the bottom to the top by the click spring 40, and the click ball 39 is fitted in the click groove 38 provided at every predetermined angle, so that the click ball 39 is felt.

A modified example using this operating member is shown in FIG. 6 (a).
~ (D). (A) is an example in which there are four displays of P, S, M, and A, and the operation member is dedicated to AE mode selection.
(B) shows five displays: low-speed continuous shooting (low-speed continuous shooting), high-speed continuous shooting (high-speed continuous shooting), single-shot (single-frame shooting), self-timer, and silent (low-speed film feeding reduces feed sound). Yes This is an example used as a drive mode setting dedicated operation member. (C) is an example of the operation member dedicated to setting the exposure correction value, which can be set in the range from -2 to +2 in increments of 1/3 EV around 0, and (d) is the operation member dedicated to setting the ISO value. In this example, it is possible to set from 25 to 6400 in 1/3 step units.

In any of the examples, the operation method is the same, and it is judged from the display condition before the operation how much the rotation operation member 5 should be rotated in which direction, and the rotation operation is performed. The selected mode or numerical value is displayed at the position of the index 6.
The display order of other modes or numerical values is displayed unchanged.

As another modified example, as shown in FIG.
Instead of arranging the liquid crystal display device 27 on the upper surface of the rotation operation member 26, the liquid crystal display device 27 can be arranged on the body. (A),
The example of (b) has seven modes similar to the example of FIG.
(A) shows the state set to P mode,
In this state, the rotary operation member 26 is operated counterclockwise by two clicks to select the S mode, and then reset to perform the P mode.

The example of (c) has four modes similar to those of the example of FIG. 6 (a). The index 28 is arranged on the upper surface of the rotation operation member 26, and the rotation operation member 26 is operated to match the index 28 with the mode display displayed on the liquid crystal display device 27 to perform mode selection. Regardless of the mode display position of the index 28, P reset can be performed by operating the P reset button 7, and when the reset is performed, the predetermined mode is set and the mode set at the position of the index 28 is displayed. To be done. After the mode is changed or the P is reset, even if the position of the mode display is changed, the display order is the same as that before the change as shown in (b).

In addition to resetting by P reset, the user's favorite mode, numerical value, etc. are stored in advance, and when P reset is performed, these contents are forcibly called and set to those contents. (Custom function, described later)
It can also be said.

Next, another modification shown in FIG.
This is an example used as an operation member for setting the SO value. A rectangular liquid crystal display device 51 is arranged on the upper surface of a rotation operation member 52 that can rotate in either direction, and the liquid crystal display device 51 does not rotate even if the rotation operation member 52 is rotated. . When you rotate it, you can feel a click at every predetermined angle.
/ 3SV) ISO value up / down operation is possible. On the liquid crystal display device 51, the ISO value is displayed in the center,
The + symbol is on the upper right, the arrow pointing up to the lower right, and the − on the upper left.
The symbol is such that an upward-arrowing arrow is displayed at the bottom left.

(A) shows a state in which the ISO value is read from the film sensitivity information provided on the film or the film cartridge and the read ISO value is displayed, which is 100 in this example. When no up / down operation is performed, the left and right displays of the numerical values are all displayed. When the up / down operation is performed, the rotation operation member 52 is operated, and when the numerical value is desired to be increased, the rotation operation member 52 is rotated in the direction of the arrow (counterclockwise) displayed below the + sign. As shown in (b), the display after the up operation is + on the right side of the numerical value.
A symbol and a rising arrow are displayed, and nothing is displayed on the left side of the numerical value. When the up operation is performed like this, +-
By displaying only the + symbol among the symbols, it is easy to understand that the initially read ISO value (hereinafter referred to as the initial ISO value) is changed to the up side.

On the contrary, the state of the display after the down operation is performed by rotating the rotary operation member 52 clockwise from the initial state of (a) is shown in (c). Contrary to the case of the up operation, the − sign and the upward rising arrow are displayed, so the initial I
It is easy to understand that the SO value is changed to the down side.

When the P reset button 7 is operated from the changed state as shown in (b) or (c), the P reset button 7 is reset and the state returns to the initial state as shown in (a). If the change amount (ΔSV) of the ISO value is already stored by the custom function, the change amount of the ISO value is forcibly read,
A value obtained by adding the initial ISO value is displayed in the center of the liquid crystal display device 52. At this time, as in (d), the numerical values and the symbols on both the left and right sides are all displayed. In the example of (d), +1/3 SV is stored as the ISO value change amount, and SV = 5
By adding (ISO = 100) and 1/3 SV, ISO =
It is set to 125.

FIG. 9 shows another modification. This is an example in which an operating member for setting an ISO value is used as in FIG. A circular liquid crystal display device 56 is arranged on the upper surface of a rotary operation member 57 that is rotatable and has a click feeling similar to the modification example, and the numerical value representing the ISO value is along the circumference of the liquid crystal display device 56. It is displayed in order by increasing the number in a clockwise direction,
The numerical value at the position of the index 58 shows the currently set value.

Similar to the example shown in FIG. 8, the initial ISO value is displayed in the initial state shown in (a), and the ISO value of the ISO value is changed by performing the up / down operation with the rotary operation member 57 from this state. Can be changed. (B) is a rotary operation member
In the display state after rotating 57 counterclockwise by one click and performing the up operation, (c) shows the state after rotating the rotation operation member 57 clockwise by one click and performing the down operation. In the display state, the set numerical value is displayed at the position of the index 58 after the up / down operation, and the other numerical values are displayed in the same order as before the operation. When the P reset button 7 is operated from the changed state, P reset is performed,
Return to the initial state as shown in (a). When the ISO value change amount (ΔSV) is stored in advance by the custom function, that value is forcibly read and the value added to the initial ISO value is displayed at the position of the index 58.

The ISO value setting is, for example, 25 to 6400.
As you can see, the setting range is very wide, and when all are displayed, one display becomes smaller. In the example shown in FIG. 9, a limited number of items are displayed before and after the set value as a center to enlarge one display.

Next, the control of the camera will be described with reference to the block diagram shown in FIG. A microcomputer 61 controls each part. The following switches are connected. Main switch SM, release button half-press switch S1, shutter release switch S2, P reset switch SP, multi-point / spot distance measuring switch SAF, multi-point / spot metering switching switch SAE, modeling flash switch SMD, pre-flash switch SPF, They are a wireless light emission switch SWR and a flash pop-up switch SPU. Of these switches, the main switch SM and the pre-emission switch SPF
And the wireless light emission switch SWR is a state switch that maintains that state once you operate it,
The other switches are of the type that are turned on only while the button is pressed and turned off when the button is released.

Inputs to the microcomputer 61 are from an ISO value reading section 67 for reading film sensitivity, a photometry section 68 for photometry, and a distance measurement section 69 for distance measurement.
There are inputs by operating the mode setting dial 62 for setting various modes, the front dial 63 for up / down of numerical values, etc., and the rear dial 64. Output destinations include a drive control unit 65 that controls film winding, a flash control unit 66 that controls flash emission, a focus control unit 70 that controls focusing based on distance measurement information, information such as photometry and ISO. There is an exposure control unit 71 that controls the exposure based on 72
The display I of the body liquid crystal display devices 11 and 73 for displaying the aperture value, the shutter speed, etc. is the liquid crystal display device 4 on the upper surface of the rotary operation member 5, and also outputs the control signals of these display portions.

EEPROM (Electrical Erasable Prog
The rammable ROM) 74 stores the information displayed on the body liquid crystal display device 11 by a custom function,
Transfers data to and from the microcomputer 61.

Table 1 shows the relationship between the RAM for storing various kinds of information and the EEPROM contents used for the custom function and the stored contents.

[0042]

[Table 1]

Describing each register in order, MDR stores one mode of AE mode (P, A, S, M), AVR stores aperture value, TVR stores shutter speed, AFR has multiple points. / Spot distance measurement switching is stored, AER stores multipoint / spot metering switching, ΔSVR is the amount of change from the initial ISO value (ΔS
V) is stored, ΔEVR is the exposure correction amount (ΔEV),
SVR stores the initial ISO value, BVR stores the brightness of the subject by photometry, and DRVR stores single / continuous shooting in the drive mode. In the above, even if the main switch 3 is turned off in the RAM, the stored contents are not erased because they are backed up by the battery, but the stored contents are erased when the battery is removed.

There is an EEPROM for custom functions,
The contents stored here will not be erased even if the battery is removed.
Describing the registers in sequence, AFRE stores the switching of multi-point / spot distance measurement, AERE stores the switching of multi-point / spot photometry, ΔSVRE stores the amount of change (ΔSV) from the initial ISO value, ΔEVRE is the exposure compensation Amount (ΔE
V) is stored, DRVRE stores the drive mode (single / continuous), MDRE is the AE mode (P, A, S, M).
It remembers one of the modes.

FIG. 11 shows a flowchart of the main routine of the control unit of the camera to which the present invention is applied. First, the process shown in FIG. 9B is performed only when the battery is attached to the camera.
In step # 23, EEPR has already been made with the custom function.
The contents stored in the OM are read out and stored in the RAM. The contents stored in the EEPROM are, as described above, the distance measuring area, the light measuring area, and the ISO value change amount (ΔS
V), exposure correction amount (ΔEV), drive mode, and AE mode. When reading is completed, step (a) in Fig.
Continue to # 3.

Even if the battery is installed, if the main switch (SW) is not turned on and remains off, it is in a stopped state. If it is determined whether the main SW is ON in step # 3, the result is No because it is not turned on, and if it is determined in step # 13 that the main SW is turned ON → OFF, the result is Yes only when the main SW is turned off from ON immediately. In this case, nothing is done, the display is turned off in step # 19, and the stopped state of step # 21 is entered. However, instead of completely stopping, the main SW is operated and waiting for an interrupt to occur. When the main SW is turned from OFF to ON, an interrupt occurs, jumping to step # 1, and the interrupt flag is set to 1. In step # 3, it is determined whether or not the main SW is in the ON state. Since the determination result is Yes, various subroutine processes for photographing in steps # 5 to # 11 are performed. There are four sub-routines: step # 5 mode setting, step # 7 S1 ON control, step # 9 data setting, step # 11 up / down control, and this routine is executed while the main SW is ON. repeat.

For normal termination, the main SW is switched from ON to OFF
Operation is performed, the determination result of the main SWON state in step # 3 is No, so the process proceeds to step # 13 and step # 13.
At 13, the main SW is turned ON → OFF. At this time, the main SW has just been turned OFF, so the determination result is Yes, and the process proceeds to the next Step # 15, and Step # 15
Then, it is determined whether or not the P button is in the ON state. Since the P button 7 is not operated here, the determination result is No. In step # 19, the display is turned off and the operation is stopped.

When the main switch is terminated from ON to OFF while the P button 7 is held down, the storage operation in the custom function is performed. The normal end is the same until the process proceeds to step # 15, but in the determination of whether the P button is in the ON state in step # 15, since the P button is still pressed down, the determination result is Yes.

Next, the process proceeds to step # 17, where R is currently in use.
The contents stored in the AM and being displayed on the body liquid crystal display device 11 are stored as a custom function. Specifically, RA
The memory contents of M are written in the EEPROM. In this embodiment, multi-point / spot distance measurement, multi-point / spot photometry, initial ISO
Information about the amount of change from the value, the amount of exposure compensation, the drive mode, and the AE mode is displayed and all of them are stored. However, depending on the model of the camera, some information may not be stored. You may make it memorize | store only.
After memorizing, the display is turned off in step # 19 to enter the stop state, and waits for an interrupt.

Next, FIG. 12 is a flow chart of the mode setting subroutine of step # 5 of the main routine of FIG. 11, which will be described. First, in step # 25, it is determined whether the interrupt flag is 1. This is because the process after Yes is required immediately after the main switch is turned from ON to ON. If it has already been turned on, the mode has already been set and the processing of Yes and subsequent steps is not necessary, so the routine proceeds to step # 45, where the ISO value is read from the film or film cartridge, and that value is substituted into the register SVR.

If the interrupt flag is 1 in step # 25, mode setting must be performed. The mode setting need only be set once at the beginning and is not necessary the second time, so the interrupt flag is set to 0 in step # 27. In the next step # 29, the contents of RAM are displayed on the body liquid crystal display device 11
To display.

Next, the set AE mode (register M
The aperture value or shutter speed is displayed on the body liquid crystal display device 11 in accordance with (stored in DR). Step # 31 is A
Whether the mode is the mode is determined. If the mode is the A mode, the aperture priority mode is set. Therefore, the process proceeds to step # 37, the aperture value stored in the AVR is displayed, and the process proceeds to step # 43. If it is not the A mode, it is determined in step # 33 whether it is the S mode. If it is the S mode, since it is the shutter speed priority mode, the shutter speed stored in the TVR is displayed in step # 39 and the process proceeds to step # 43. If it is not the S mode, it is determined whether it is the M mode in step # 35. If it is the M mode, it is the manual mode, so the aperture value stored in the AVR is displayed in step # 41 and stored in the TVR in step # 39. Step # 43 with the shutter speed displayed
Go to. If it is not the M mode, it is the P mode, so the aperture value and shutter speed are not displayed and the process proceeds to step # 43.

In the next step # 43, the dial setting I subroutine is processed. This dial setting I subroutine is performed by the liquid crystal display device 4 arranged on the rotary operation member 5.
Is displayed, and then the process proceeds to step # 45. Step #
In 45, IS from film or film cartridge
The O value is stored in the read register SVR. This completes this subroutine and returns to the main routine.

13 and 14 show S1 of step # 7 of the main routine shown in FIG. 11 (release button half-press switch).
It is a flowchart of an ON control subroutine. When S1 is OFF, this subroutine is ended without doing anything and the process returns. In step # 47, it is determined whether S1 is operated from OFF to ON, and if the result is Yes, step
Performs the dial setting I subroutine of # 49. No
If so, it is determined in step # 51 whether S1 is ON.
When S1 is already turned on and the on state is maintained, the step # 49 dial setting I subroutine has already been processed, and the processing is skipped to the next step # 53.

In step # 53, it is determined whether or not multi-point distance measurement is performed. If Yes, focus adjustment is performed by multi-point distance measurement in step # 55, and if No in step # 57 by spot distance measurement. In the next step # 59, it is determined whether or not multi-point photometry is performed. If Yes, multi-point photometry is performed in step # 61, and if No, spot brightness is measured in step # 63, and the value is measured. Store in register BVR. Next step # 65 is EV
Calculate the value. Luminance of the subject (BV
(Stored in R), the initial ISO value (stored in SVR), the amount of change from the initial ISO value (stored in ΔSVR), and the exposure correction amount ΔEV (stored in ΔEVR)
Find the value.

In the next step # 67, it is determined whether or not the flash emission is turned on. If the flash is ON, the flash synchronized shutter speed TVFL is set as the shutter speed in the TVR in step # 69, and in step # 71, the exposure calculation is performed according to the EV value, the TV value, and the AE mode to calculate the AV and the AVR. Remember. If the flash emission is not ON, in step # 73, E
Exposure calculation is performed according to the V value and the AE mode to calculate TV and AV, and these are stored in TVR and AVR. AV in S mode,
TV is calculated in the A mode, and TV and AV are calculated in the P mode. The aperture value AV or the shutter speed TV obtained by the exposure calculation in step # 71 or step # 73 is
It is displayed on the body liquid crystal display device 11 at # 75.

In step # 77, it is determined whether or not the shutter release switch (S2) is on. S2 is O
If it is in the OFF state instead of N, it is not in the photographing stage yet, so this subroutine is terminated and the process returns. If S2 is turned on, it means to shoot, so the next step
Exposure control is performed at # 79. The exposure control subroutine is shown in FIG. 15 and will be described later. When one frame is photographed by the exposure control, the operation for the next photographing is performed. Step # 8
The film winding operation is performed in step 1, and step # 83
At, mechanical charge such as shutter charge and mirror charge is performed.

Next, in step # 85, it is determined whether the drive mode (stored in the register DRVR) is single shot. In the case of a single shot, it is determined in the next step # 87 whether S1 is OFF, and when the release button is pressed down, S1
The loop is repeated in step # 87 until is turned off. When S1 is turned off, this subroutine is terminated and returns. Step # 8 if the drive mode is continuous shooting
In S9, it is determined whether or not S2 is turned on. If it is still turned on, the process returns to step # 53 to repeat the operations for the next shooting, such as distance measurement, photometry, and exposure calculation.
If S2 is OFF in # 89, this subroutine is terminated and the process returns.

FIG. 15 is a flowchart of the step # 79 exposure control subroutine in the S1ON control subroutine of FIG. First, flash light is turned on in step # 91.
Then, in the next step # 93, it is determined whether pre-emission is ON. If YES in either judgment, that is, if the flash emission is ON and the pre-emission is ON, the flash pre-emission is performed in step # 95, and the constant time WAI until the main emission is obtained in step # 97.
T. If the flash emission is OFF or the pre-emission is OFF, these steps # 95 and # 97 are not necessary, so skip them and proceed to the next step # 99.

In step # 99, it is determined again whether or not the flash emission is ON. If it is OFF, aperture control is started in step # 109, and shutter control is started in step # 111. If it is ON, aperture control is started in step # 101, and shutter control is started in step # 103. Next, in step # 105, it is determined whether or not the wireless light emission mode is ON. If the wireless light emission mode is ON, flash light emission for wireless flash control is performed in step # 107, and otherwise normal light emission is performed in step # 113. Flash the flash. This is the end of this subroutine and returns.

Next, a flow chart of the data setting subroutine of step # 9 of the main routine will be described with reference to FIG. If the dial has not been changed, the already set mode is displayed and continues to be displayed. In step # 115, the dial change amount is input by operating the dial (rotation operation member 5), and in step # 117, the setting mode is determined from the dial change amount. The liquid crystal display device 4 is displayed in the dial setting II subroutine of step # 119 so that the display of the decided setting mode comes to the position of the index.

At step # 121, it is determined whether or not the multipoint / spot distance measurement switching button 10 has been operated. If so, at step # 123 the multipoint / spot is switched and stored in the register AFR. Next, in step # 125, it is determined whether or not the multipoint / spot photometry switching button 9 has been operated, and if it has been operated, the multipoint / spot is switched and stored in the register AER in step # 127. If both operation buttons 9 and 10 are not operated, nothing is done.

In the next step # 129, the P reset switch SP is turned on by depressing and releasing the P button 7 once.
It is determined whether or not it has changed from N to OFF. When the P reset switch SP is operated from ON to OFF, P reset is performed, and the custom function shown in the flow chart of the main routine (FIG. 11) stores (when the P button 7 is pressed down, the main switch 3 is turned ON → OFF. In step # 131, the stored information is read from the EEPROM into the RAM. In the next step # 133, the dial setting I subroutine, the AE mode read from the EEPROM is displayed on the liquid crystal display device 4 so that the index position is reached. When the custom function is not set, the AE mode is set to the P mode, and other settings are set to predetermined setting contents. In step # 135, the body liquid crystal display device 11 is subjected to EEPR.
Display the contents read from the OM. If the P button is not operated, these steps # 131, # 133 and # 135 are skipped and the process proceeds to the next step # 137.

In step # 137, it is determined whether the modeling light emission mode is ON, and in step # 139 it is determined whether the wireless light emission mode is ON. Both judgments are Y
In the case of es, that is, when modeling light emission or wireless light emission is performed, modeling control is performed in step # 141. That is, the flash of the main body is caused to emit light and a control signal is sent to the wireless flash. If the modeling light emission mode or the wireless light emission mode is OFF, there is no need to perform modeling control, so this subroutine is terminated and the process returns.

FIG. 17 shows a flowchart of the dial setting I subroutine. The dial setting I is the liquid crystal display device 4
When it is necessary to display any of the AE modes at the index position, processing is performed. This is necessary immediately after the main switch is changed from OFF to ON, immediately after P reset, and S1 (release button half-press switch).
Immediately after the switch from OFF to ON. In step # 143, the selected AE mode is displayed at the index position of the liquid crystal display device 4 arranged on the upper surface of the rotation operation member 5.
In step # 145, other modes are displayed centering on the mode displayed at the index position, but the manner of mode display is predetermined, and in the present embodiment, as shown in FIG. , S, M, ISO value setting, drive, and exposure correction are displayed in this order.

FIG. 18 shows a flowchart of the dial setting II subroutine. The dial setting II is carried out when all the modes displayed on the liquid crystal display device 4 are selected by operating the rotary operation member 5. step 1
At 47, the symbol of the selected mode among the seven modes shown in FIG. 4 is displayed at the index position of the liquid crystal display device 4. In step # 149, the other modes are displayed in a predetermined order centered on the mode selected and displayed at the index position.

FIG. 19 shows a flowchart of the up / down control subroutine. This subroutine is front dial 1
3. This is a subroutine for changing various values according to the dial change amount when the rear dial 14 is operated, and the contents to be changed differ depending on the mode selected by the operation of the rotary operation member 5.

In step # 151, the front / rear dial change amount is input. In step # 153, it is determined whether the mode selected by the rotary operation member 5 is one of the AE modes. If selected, the shutter speed (according to the AE mode selected in step # 155) ( T
V) and aperture value (AV) are changed. If it is not the AE mode, it is determined in step # 157 whether the ISO value setting mode is set. If Yes, the initial IS is set in step # 159.
The change amount (ΔSV) from the O value is changed. If it is not the ISO value setting mode, it is determined in step # 161 whether it is the exposure correction mode. If Yes, the exposure correction amount (ΔEV) is changed in step # 163. If it is not the exposure compensation mode, it is the drive mode, so in step # 165, continuous shooting / single shooting is switched.

The contents changed in each mode are displayed on the body liquid crystal display device 11 in the next step # 167, the present subroutine is terminated and the process returns to the main routine.
