FIG. 9 is a flowchart for explaining an interruption process when either the photographing preparation switch 9 or the function button 10 is turned on.

Shooting preparation switch 9 (indicated by S ₁ in the flowchart)
Alternatively, use the function button 10 (in the flowchart,
(Indicated by S _FUN ), it is first determined whether or not the function button 10 has changed from off to on (step # 2). Note that it may be determined which one is turned on.

When it is determined that the function button 10 has been turned on from off (YES in step # 2), a process for mode change shown in FIG. 10 is executed (step # 4).
When 5 seconds have elapsed after the execution of the predetermined processing (YES in step # 6), the processing content displayed in the finder screen is turned off (step # 8). On the other hand, when it is determined that the shooting preparation switch 9 has been turned on from off (NO in step # 2), the processing shown in FIG. 18 when the shooting preparation switch 9 is turned on is executed (step # 10). ). At this time, if the photographing preparation switch 9 is turned off (YES in step # 12), the display content is turned off in step # 8.

FIG. 10 is a flowchart illustrating an operation procedure for changing the mode when the function button 10 is turned on from off. Hereinafter, an operation procedure for this mode change will be described with reference to FIGS.

In the drawing, the mode I is the exposure correction “+/−”
Mode II means that the above-mentioned first group including the AF area is selected.
This means that the above-described second group including O and single-shot and continuous-shot drives is selected.

First, in step # 20, the fast mode flag MIF
Is 1 or not. Thus, it is determined whether the process is in the first routine after the function button 10 is turned on.

In the first routine (NO in step # 20), in step # 22, whether the mode selected last time was I or not, II
Is determined. That is, suppose that the mode II was selected in the setting operation at the time of the previous interrupt when the function button 10 was turned on (the mode #
II) In this interrupt, the setting operation is performed for mode I, and the mode flag is set to mode I in step # 24.
Is changed to Conversely, in the setting operation at the time of the last interrupt,
Assuming that the mode I has been selected (mode I in step # 22), it is assumed that the setting operation is to be performed for mode II in this interrupt, and the mode flag is changed to mode II in step # 34.

As described above, the selection of the function mode is interrupted every time the function button 10 is turned on, and is set to another function mode or cyclically changed.

When the mode is changed to the mode I, the exposure correction “+/−”, which is a function that can be set in the mode I, and the contents and marks related to the AF area are changed to the eleventh mode.
As shown in FIG. 12 and FIG. In addition, of display contents, mark,
For some, the settings in the previous mode I are displayed. As a result, the previous settings can be checked, and if it is determined that there is no need to change the settings as described later, the settings are simply left as they are, and the same settings as the previous settings are set. Can be achieved quickly.

In this example, the previous exposure correction amount ΔEV is displayed as an apex value, for example, 1.0 on the two-digit display unit 51 (step # 26). Next, the current posture of the camera 30 is determined by the posture detecting means 13. Orientation of the camera 30 is to be lateral position (at step # 28 NO), area a for a selectable distance measurement in the lateral position, as shown in FIG. 11, b, c, d and wide area W ₂ Each mark is displayed blinking to indicate that it is in a selectable state (step # 30). On the other hand, when the posture of the camera 30 is the vertical position (YES in step # 28), the areas a, c, and
d and the marks of the wide area W ₁ is flashing to indicate that a selected state (step # 32). Subsequently, in addition to the dial mark 44, a "+/-" mark 45 representing the function in mode I, an AF mark 46, and their selection marks 450 and 460 are displayed, and the other displays are turned off (step S1). # 42, # 44). Thereafter, the fast mode flag MIF is set to 1, the built-in timer is reset, and the time count for 5 seconds is started (steps # 46 and # 48). Then, the process returns to step # 6 in FIG.

On the other hand, if the mode has been changed to mode II in step # 34, then the contents and marks related to the film sensitivity ISO and the single-shot and continuous-shot drives, which are functions that can be set in mode II, are displayed. Are displayed on the in-screen display portion 41 and the out-of-screen display portion 42 as shown in FIG. That is, first, the previous film sensitivity SV is displayed on the four-digit display section 50, for example, 100
Is displayed (step # 36), and the contents of the previous single-shot and continuous-shot drives are displayed (step # 38). In the example of FIG. 13, a letter “S” representing a single shot is displayed in the S / C mark 48. Further, the currently selected area (in the previous mode I) is displayed (step # 40).
In the example of FIG. 13, it can be seen that the wide area W ₂ is selected. Then, in step # 42, the dial mark 44
In addition, the mode II ISO mark 47, the S / C mark 48, and their selection marks 470, 480 are displayed. Then, as described above, the other displays are turned off, and the first mode flag MIF is turned off.
After the respective processes of setting to 1 and reset start of the built-in timer are performed (steps # 44 to # 48), the process returns to step # 6 in FIG.

In step # 6, if the setting operation of the function content is started before the lapse of 5 seconds, the flow of mode change (step # 4) is continued.

When the previous setting contents are displayed in the in-screen display portion 41 and the out-of-screen display portion 42 of the finder as described above, the flow returns to step # 20, and the state of the first mode flag MIF is changed. Is determined. Here, that is, in the second and subsequent routines, the fast mode flag
Since MIF is set to 1 (YE in step # 20)
S), the process proceeds to a step # 50, and it is determined whether or not the mode I is selected.

When the mode I is selected, first, it is determined whether or not the front up / down dial 11 (shown as Sud ₁ in the flowchart) is rotated (steps # 52 and # 5).
6, see Figure 14). That is, up-down dial 1 before
When 1 is rotated right (YES in step # 52), 0.5 is added to the exposure correction amount ΔEV as an apex value, and the progress of the addition is displayed on the two-digit display unit 51 as an apex value, for example, 1.0 (step # 52). # 54, # 60). At this time, the area already selected (as described later, in the first operation after the fast mode flag is set to 1), the rear up-down dial 12 is operated first, or in the mode I at the previous interruption. set) with is displayed on (in the example of Figure 14, the wide area W ₂ is selected), the function of the AF area selection mark 460 to indicate that it is not currently set is turned off. On the other hand, when the front up-down dial 11 is rotated counterclockwise (step # 52)
, NO in step # 56), the apex value of 0.5 is subtracted from the exposure correction amount ΔEV, and the result of the subtraction is expressed by a two-digit display unit 5.
For example, it is displayed as an apex value of 1, for example, 1.0 (steps # 58, # 60).

Next, if the front up-down dial 11 has not been rotated in any of the left and right directions, it is determined whether or not the rear up-down dial 12 (indicated by Sud ₂ in the flowchart) has been rotated (step S1). # 52, 56 both NO, Step # 66,
# 70). Each time the rear up-down dial 12 is rotated clockwise (YES in step # 66) or counterclockwise (NO in step # 66, YES in step # 70), a screen corresponding to the distance measurement area is displayed. The selection of the area of the inner display portion 41 is cyclically performed in the forward direction or the reverse direction (steps # 68 and # 72, see FIG. 15).

In FIG. 15, all the area marks that may be selected are shown for convenience, but actually, only one of them is selected and displayed as described later. You.

When operating the rear up-down dial 12 for the first time,
As shown in steps # 30 and # 32, selectable areas are displayed blinking, and the area can be selected within them. When the area is selected by rotating the rear up-down dial 12 right or left, the selected area is taken in as the setting area AR. Subsequently, the posture of the camera 30 is detected (Step # 76). The camera 30 is a lateral position, yet set when area AR is a wide area (step # 76 in YES, YES in step # 78), wide area W ₂ is taken as the setting area AR (step #
80). If any other area is selected (NO in step # 78), the area in step # 74 is used as it is as the set area AR.

The camera 30 is a vertical position, moreover when setting area AR is wide area wide area W ₁ is taken as (NO at step # 76, YES in step # 82), setting area AR ( Step # 84). If the setting area AR is the area b (YES in step # 86), the area b is not selectable in the vertical position, and if the rear up-down dial 12 is rotated right, the area b And the area c is taken in as the setting area AR (YES in step # 88, step # 90).
Instead of area b, area a is taken in as set area AR (NO in step # 88, step # 92). Also the area
When a, c, d are selected (NO in step # 86),
The selected area is set as the setting area AR as it is. When the setting of the area is completed, the setting area AR is illuminated and displayed, the exposure correction amount ΔEV of the two-digit display unit 51 is turned off, and the function of the exposure correction “+/−” is not currently being set. The selection mark 450 is turned off to indicate (steps # 94 to # 98). Subsequently, after step # 48 and step # 6 (FIG. 9), the process returns to step # 20, and further proceeds to step # 52.

When the correction exposure amount ΔEV is to be further changed, the front up / down dial 11 is continuously rotated left or right until the desired exposure correction amount is obtained in step # 52 or step # 56. When the area is further changed, the rear up / down dial 12 is continuously rotated left or right until a desired area can be set in step # 66 or step # 70.

When the state in which none of the front and rear up-down dials 11 and 12 is operated for 5 seconds or more elapses, it is regarded that the setting is completed, and all displays are turned off (FIG. 9, step # 8). In the AF area function, a selectable area may be lit and displayed, and the selected area may blink.

Next, when the mode II is selected (step # 50)
First, it is determined whether or not the front up-down dial 11 has been rotated (steps # 100 and # 104, see FIG. 16). That is, when the front up-down dial 11 is rotated right (YES in step # 100), an apex value of 0.5 is added to the film sensitivity correction value ΔSV, and the sensitivity value SV _DX ( The value SV to which the apex value has been added is displayed as, for example, 100 (apex value 5) on the four-digit display unit 50 as shown in FIG. 16 (step # 102, step # 108, # 110). The reason for not displaying the apex value simply is to take into account the familiarity of the photographed image, and any value may be displayed. Then, the selection mark 480 is turned off to indicate that the function of the single-shot or continuous-shot drive is not currently being set,
The selected area is displayed (Step # 11)
2, # 124). On the other hand, when the front up-down dial 11 is rotated counterclockwise (NO in step # 100, YE in step # 104)
S), an apex value of 0.5 is subtracted from the film sensitivity correction value ΔSV, and a value SV obtained by adding the sensitivity value SV _DX (apex value) read from the film tube to the subtraction result is displayed on the two-digit display unit 51, for example. As described above, it is displayed as 100 (apex value 5) (steps # 106, # 108, # 11).
0) Then, the selection mark 480 is turned off to indicate that the single-shot and continuous-shot drive functions are not currently being set, and the selected area is displayed (steps # 112 and # 124).

Next, if the front up-down dial 11 has not been rotated in any of the left and right directions, it is determined whether the rear up-down dial 12 has been rotated (NO in steps # 100 and 104, step #). 114). Each time the rear up-down dial 12 is rotated clockwise or counterclockwise (step # 11
(YES in 4), single shooting S and continuous shooting C are alternately changed and set (step # 116). If a single drive is set,
The letter S is displayed in the S / C mark 48 as shown in FIG. 16, and when the continuous shooting drive is set, the S in the S / C mark 48 is displayed as shown in FIG. Only the characters are erased (step # 118). Thereafter, the film sensitivity value and the selection mark 470 are erased to indicate that the function of the film sensitivity correction ISO is not currently being set, and
The selected area is displayed (Step # 120-
# 124).

FIG. 18 is a flowchart for explaining the operation when the shooting preparation switch 9 is pressed. Hereinafter, this operation is referred to as
This will be described with reference to FIG.

When the shooting preparation switch 9 is turned on and an interrupt is started, first, the display of the modes I and II, that is, the dial mark 4
4, "+/-" mark 45, AF mark 46, ISO mark 47 and S / C
The mark 48 and the other selection marks 450 to 480 are turned off, while the previously set area is displayed (step # 13).
0, # 134).

At this time, the fast mode flag MIF is reset to 0 (Step # 132). By resetting the first mode flag MIF, the process of displaying the previous setting contents is executed prior to the setting operation procedure at the next interruption of the function button 10 being turned on (NO in step # 20). , Steps # 22 to # 46).

Subsequently, the subject brightness BD obtained by the photometric circuit 4 is fetched, and further, a film sensitivity value SV _DX from a film tube (not shown).
Is read, and the above film sensitivity correction value ΔSV is added to the film sensitivity value SV _DX (steps # 136 to # 14).
0). Then, the subject brightness BD is added to the corrected film sensitivity value SV to obtain an exposure amount EV, and further, an exposure correction amount ΔEV is added to the obtained exposure amount EV. From the corrected exposure value EV, the aperture value Av and the shutter speed Tv are obtained based on the relationship between the aperture value Av and the shutter speed Tv with respect to a preset exposure value (steps # 142 to # 146). This aperture value Av and shutter speed Tv
Is displayed on the off-screen display portion 42 as shown in FIG. 19 (step # 148). The aperture value Av and the shutter speed Tv are also displayed on the on-body LCD 32.

Next, each of the distance measurement areas 2 a to 2 d obtained by the focus detection circuit 2
And the shift amounts DFA to DFd are calculated from the AF data (steps # 150 and # 15).
2). Next, the area selected and set by the AF area function is determined (step # 154). That is, when the wide area W ₁ is selected, the deviation amount DFa,
DFc, the average value obtained from DFd, or the optimal shift amount by considering also the contrast state or displacement amount obtained by the method in consideration of both methods is taken as the set displacement amount DF, selected wide area W ₂ is DFA ~ DFd
The deviation amount obtained by the same method as described above is taken in as the deviation amount DF (steps # 156 and # 15).
8). When the area a is selected, the shift amount DFa is set as the set shift amount DF, and when the area b is selected, the shift amount DFa is set.
DFb is set as the set shift amount DF, the shift amount DFc is set as the set shift amount DF when the area c is selected, and the shift amount DFd is set as the set shift amount DF when the area d is selected (step # 160). , # 162, # 164, # 166).

When the set shift amount DF is captured as described above, the set shift amount DF is compared with the allowable level value k (step # 168). That is, if the set shift amount DF is within the allowable value k, it is determined that the camera is in the in-focus state, and the in-focus display is performed (step # 170). This in-focus display is performed by turning on the in-focus display section 49 as shown in FIG.
The photographer can easily confirm the focus. On the other hand, if the set shift amount DF is larger than the permissible value k, it is determined that it is not within the permissible in-focus range, and no in-focus display is performed. The display is turned off (step # 172). And in this case, F
It is determined whether the mode is the A mode or the AF mode (step # 174).
In the case of FA mode, the setting deviation amount
DF is displayed as a bar on the FA meter display section 43 (step # 17)
Four). Then, the photographer manually operates the lens drive while watching the bar display to bring the lens into focus. In the case of the AF mode, the lens is automatically driven by the set deviation amount to bring the lens into a focused state, and the FA meter display used for assisting the FA mode is turned off because it is unnecessary (step # 178, # 180). This operation is performed while the photographing preparation switch 9 is pressed (FIG. 9, step # 12).
NO), repeated. Then, when the shooting preparation switch 9 is released (YES in step # 12), the display contents up to that point are turned off (step # 8).

FIGS. 20 to 24 show other display examples of the finder surface screen. As shown in the drawing, the selection mark is composed of instruction marks 70 and 71 and selection marks 451 to 481 corresponding to each function.

In FIG. 20, marks indicating mode II functions are shown.
47 and 48 are marks 45 and 46 indicating the function of mode I.
Are displayed on the same side.

FIGS. 21 and 22 show a first instruction method for mode selection in FIG. 20, and FIGS. 23 and 24 show a second instruction method.

The first instruction method is performed by lighting and erasing the selection marks 451 to 481. That is, when the mode I is selected, as shown in FIG.
1,481 is turned off. If mode II is selected,
As shown in FIG. 22, the selection marks 451 and 461 are turned off.

The second instruction method is to use marks 45 to 48 of each function.
And the corresponding selection marks 451 to 481 are turned on and erased in pairs. That is, when the mode I is selected, as shown in FIG. 23, the ISO mark 47, the S / C mark 48, and the corresponding selection marks 471, 481 are erased. When the mode II is selected, the "+/-" mark 45, the AF mark 46 and the corresponding selection marks 452, 462 are deleted as shown in FIG.

In the present embodiment, the selectable area and the selected area can be identified by lighting or blinking in the AF area function, but can also be identified by changing the lighting brightness, blinking cycle, and the like. You can also
Also, the color may be identified by color display.

Further, in the present embodiment, there are four functions and these are divided into two groups of two, but the present invention can be applied to a case where there are many functions. For example, the six functions may be divided into three groups so that the group can be changed cyclically, or may be divided into two groups, and a selection operation member of a cyclic type or for each group and the contents of the function May be provided. Further, a two-stage selection operation member may be provided such that a function is divided into large groups and the functions are further divided into small groups. In this case, for example, if eight functions are first divided into a large group including four functions and then into a small group including two functions, in the cyclic method, two selection operation members are used. At the same time, the number of operations is up to two times, which is less than the case where only two functions are selected cyclically (up to four times).

If functions that are closely related to each other are grouped into the same group, the camera becomes easier to use. For example, in continuous shooting mode, a moving subject is often photographed, and a wide area that can easily capture the subject is suitable for the ranging area. In single shooting mode, a focusing area is used to focus on a desired part when shooting a still subject. May be selected.
Therefore, when the drive motor is changed, the distance measurement area is often changed at the same time, and if these functions are placed in the same group, the time required for the setting operation is reduced.

The device to which the selection operation member and the setting operation member are applied is not limited to a camera, but can be applied to all devices that can be operated under setting conditions of a plurality of functions. .

【The invention's effect】

As described above, according to the present invention, in a state where the contents of a plurality of functions belonging to the group selected by the group selecting means are displayed simultaneously, the photographer can visually recognize the contents of the manually set shooting conditions. Can be. In particular, in a state where a plurality of functions belonging to the group selected by the group selecting means are simultaneously displayed, which function data is set is displayed by a mark.
The set data is easily confirmed.

Since a plurality of setting members are provided so that data can be set in a plurality of functions, the contents of each function can be set and confirmed while looking through the finder.

Further, during the setting by the manual operation means, the data of the function to be set is blinked and displayed by the index, so that it is easy to grasp and confirm the setting contents.

Further, since the contents of the function belonging to the selected group are displayed, a lot of setting contents are displayed unnecessarily on the finder screen, and confusion does not occur, and the subject image becomes difficult to see. Is also prevented.

Further, the function data is turned off except when the function is set, so that a suitable finder display of the subject image can be displayed in a shooting preparation stage or the like, and power can be saved by turning off the light when unnecessary. it can.

Further, since the manual operation means is schematically displayed to display the mark, the manual operation means can be easily operated while looking through the finder.
