Abstract

PURPOSE:To improve the associative property of a function display and to easily understand what is selected by displaying simultaneously and minutely not only the display of a first function which is selected but the display of a second function of non-selection. CONSTITUTION:In case of executing a spot AF display in an AF zone display, not only a spot AF mark Seg3 but a wide AF mark Seg2 are displayed simultaneously and minutely. Accordingly, the spot AF mark Seg3 is viewed in a form which is compared with the wide mark Seg2, and as a result, the spot AF mark Seg3 can be associated easily. In such a case, the wide AF mark Seg2 is displayed more minutely than usual, therefore, such illusion and confusion as the wide mark Seg2 is selected are not generated at all.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a camera, and more particularly to a camera that displays a selected function in response to switching of functions.

Conventional mangichi cameras have achieved A by adopting a multi-segment ranging system.
It is now possible to switch the F (autofocus) area,
Correspondingly, spot AF. Wide (program) A
It is designed to display area F. A method is used to display these images using marks shaped like individual AF areas. For example, a rectangular mark is used for Subo-AF, and a mark indicating a large area is used for Wide AF area.

The sun is about to change.

However, in the conventional example, for example,
In the case of F, only a small square mark is displayed, so
There is a problem in that it is difficult to associate the spot state of the AF area.

An object of the present invention is to provide a novel camera that solves these problems.

In order to achieve the above object of Section 7, in the present invention, the first function is switched in response to switching between the first function and the second function by the function switching means.
In the camera, the display means displays the first function when the first function is selected, and displays the second function when the first function is selected. The second function display corresponding to the function is displayed thinner than when the second function is selected.

With this configuration, for example, in the case of spot AF display, the wide AF mark is displayed thinly in addition to the spot AF mark, so the spot AF mark can be visually recognized in contrast to the wide AF mark, and as a result, Spot AF
It becomes easier to remember.

At this time, the wide AF mark is displayed thinner than usual, so there is no illusion or confusion that wide AF is selected.

Back side - Seiichimasu Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a block diagram of the entire camera display system in this embodiment. In the same figure, a control unit (1) composed of a microcomputer is supplied with a voltage obtained by dividing the output voltage of a battery (2) installed in the camera by resistors (R1) (R1), A power supply voltage is provided by stabilizing the output voltage of step 2) using DC/DCC/equation (3).

These switches are the CAS switch (ScAs) used to input the film sensitivity value, the main switch (SN) that is turned on when using the camera, the AP zone switch (h), and the drive switch (So) for setting the drive mode. , mode switch for setting exposure mode (
SHOD), up switch (S, , ), down switch (So), photometry switch (Sl) for starting photometry, release switch (S2), and AV switch (SAV) for changing aperture.

The positions where each switch other than the CAS switch (Scas) is provided on the camera body (10) are shown in FIG. Here, the AP zone switch (S2), drive switch (SO), and g output mode switch (SJl) are selected.

. ) is a normally open switch that turns on when you press the operation key and turns off when you release it. Metering switch (
S, ) and release switch (S) are driven by pressing one shutter button (15), half-press turns on the metering switch (S,), and full press turns on the release switch (S). .On the other hand, the main switch (sM
) is a sliding switch that selectively selects the ON position and OFF position, and the up switch (S, , ) and down switch (S4.,) are the up/down keys (1
6) is a sliding type.

When the up/down key (16) is slid in the (a) direction, it turns on the down switch (Sa,), and when it is slid in the (b) direction, it turns on the up switch (S, p).
It is spring-biased so that it returns to the intermediate position when you release your hand.

Next, various display configurations according to this embodiment will be explained with reference to each flowchart. First, FIG. 5 shows a flowchart of the operation of the control unit (1) regarding display.
When the battery (2) is attached to the camera body (10) (15), the control unit (1) checks the remaining battery power (110).
and starts a 5 second timer (1115)
, this timer is built in the microcomputer that constitutes the control section (1). Next, the display section (8) (9)
120), and input information indicating the state of the main switch (SH) (+125). After that, step (1
In step 30), it is determined whether the main switch is turned on. Here, if the main switch (-) is ON, display data is created according to the states of the various switches according to the flowchart in FIG. 6, which will be described later, and the next step (l1
40) determines the state of the 5-second timer. If the 5-second timer is counting, activate the remaining battery power data creation section (155) to create remaining battery power data, and display the display IC (
6) Send display data to. This allows the display section (8
) In (9), a display including the remaining battery level is displayed.

If the main switch (island) is in the ON state in step (165), the process returns to step (+120) and the flow from step (165) onwards is repeated.

Main switch (S,) in step (130) above
In the state judgment, the main switch (SN) is OFF.
If F, the process advances to step (1145) and the remaining battery level is determined. Here, there is sufficient remaining power level (A),
If it is present (B) or low (C), proceed to step (160) without creating remaining battery power data [that is, press step (1155)], and proceed to step (160).
The remaining battery level is not displayed, and nothing is displayed on the display sections (8) and (9).

On the other hand, when the remaining battery level is zero (D), the remaining battery level data is formed by stepping from step (145) to the steering knob ($55), so the following step ( At step 160), the remaining battery level is displayed.

At this point, check the status of the main switch (S,) again based on the information input in step (125) above (#65)
, if the main switch (Sl) is OFF, proceed to steps (1170) and (175) and wait for the main switch (S,) to be turned ON again; then, if the main switch (Sl, I) is OFF When the state changes to the ON state, the process goes to step (110), and the step (1110)
Execute the following flow.

In the above step (140), when the 5 second timer has finished counting, or when the switch (Sl) is turned on.

. )(so)(sz)(S,,,)(S4.,) was conspired and the count was forced to end (Su-, St- only when the exposure mode is manual) If so, the process proceeds to step (150) to determine the remaining amount level.

The determination here is to sort between (A), (B), and (C) and (D). Then, in the case of (A) or (B), step (1155) is skipped to proceed to step (1160) without creating display data regarding the remaining battery level, while (C) or (D) In this case, display data of remaining battery power is created in step (1155), and then the process proceeds to step (1160).

In this way, considering step (145) and its related steps, consideration has been made to notify the photographer even if the main switch (-) is OFF when there is no remaining battery level. On the other hand, the battery level is low (C), sufficient (A), or present (8)
If the main switch is OFF, this will not be displayed.

Furthermore, according to steps (140) and (150) and related steps, even if the main switch is ON, after a certain period of time (5 seconds), the battery is low (C
) or not (D), the remaining battery level is displayed, and when there is enough (A) or there is (B), the remaining battery level is not displayed. In addition, the switch (Sl) (SHall
) (so) (sz) (s,tp) (s,
, ) is performed, (S, p, S
, , is displayed only when the exposure mode is manual), similarly, it is displayed only when (C) or (D), and (A) or (B)
However, considering the small display space, it is difficult to display the remaining battery level when a new display is required by operating a switch, and it is difficult to display the remaining battery level when a new display is required. This is because it is not something that should be prioritized based on the situation. Furthermore, when the main switch (SH) is ON, this is displayed only within a certain period of time regardless of the remaining battery level. However, switch (Sl) (SIIOD
) (SO) (SZ) (S-p) (I4.l)
When any of the following is operated (S, , S, is limited to when the exposure mode is manual), the remaining battery level is (A) or (B) above even within that certain period of time. will no longer be displayed.

Next, details of the creation of display data in step (135) of FIG. 5, that is, the creation of display data according to the states of various switches, are shown in FIG. 6 and explained.

In FIG. 6, it is first determined whether the photometry switch (S, ) is ON or not. When the switch (S,) is ON, the process proceeds to step (1120) and the brightness (
Bv) data and film sensitivity value (SV
) The data is input manually, and then the exposure mode is determined in step (11125). Here, when in program mode (P mode), shutter speed (TV) and aperture value (
AV) is calculated (1130), and (TV),
(AV) display data is created (11135), and the process proceeds to step (1145). If the manual mode (M mode) is determined in step (1125), metered manual display data is created in step (1140), and the process proceeds to step (1145). Create display data.

Thereafter, in step (11150), the 5-second timer is forcibly terminated, and the process proceeds to step (1205). In step (l1205), the exposure mode is determined, and if it is P mode, the process proceeds to step (1265).If it is 0M mode, the aperture value (AV) is increased or decreased using the up/down key (16) in step (+1210). A selection is made as to whether the shutter speed (T,) should be amplified or down.

That is, the Av changeover switch (SAv) is OFF here.
If it is ON, the shutter speed (TV) can be varied, and if it is ON, the aperture value (AV) can be varied.

Then, in step (1215), the up switch (S,
, ) is ON, the process advances to step (11220) and the TV value is incremented by 0.5EV; if it is OFF, the down switch (Sdl
Determine whether l) is ON or OFF. The down switch (S
If a,) is ON, the process proceeds to step (+1230) and the TV value is decremented by 0.5EV, and if it is OFF, nothing is done. Steps (11220), (1230
), proceed to step (1255), and proceed to step (12
If it is OFF in step 25), proceed to step (I255). Steps (1235) to (I2) related to changing the AV value
60) is also similar to steps (11215) to (11230) regarding changing the TV value, so the explanation will be omitted.

In step (1255), the 5 second timer is forcibly terminated, and in the next step (1260), (TV) (AV)
Create display data for and proceed to step (I265).
In step (I265), display data for the AF zone is created, in the subsequent step (11270), drive mode display data is created, and in step (I275), display data for exposure mode is created, and the process returns.

The switch (S,) is turned OFF in the above step (11100)
When F, proceed to step (I105) and onward, and press the mode switch (5N.p), drive switch (SD),
If any of the AP zone switches (I2) is turned on, the routine proceeds to the display data creation routine corresponding to the switch in the ON state.
) is ON, first the up-down monitor routine (
In steps (11155) and (11160) of 17), the up switch (Sup) and down switch (si,
) and the up switch (S, p) is turned on.
or when the down switch (34M) is ON, the process advances to step (11165) to change the AF zone data. Changing this AF zone data is to change settings between spot and wide. Then, the step (
After making the changes in step (11165), step (1170)
Proceed to. When both the up switch (S,,) and down switch (Sdll) are OFF, the step
165) and skip Step 165).

Proceed to (11170). In step (11170),
Create display data for the AP zone.

Of the above switches, the drive switch (SO) is
If N, go to step (1175); if mode switch (SMOD) is ON, go to step (1190)
These steps (1175) (
11190) is the up-down monitor routine (1
7), only the blocks are shown and the flow configuration is omitted.

In the above step (11175), the up switch (SuI)
, ) or when the down switch (Sdfi) is ON, change the drive mode data (single shooting □ continuous shooting) in step (#180), and then change the drive mode data (single shooting □ continuous shooting), and then
5) Select the up switch (sup) or down switch (
S47) is OFF, step (1118
0) to create drive mode display data.

Step (cloud 190), (cloud 195), (12
The operation of 00) is the same as that of the AF zone and drive mode described above, except that the operation is related to the exposure mode, so a description thereof will be omitted.

After creating the display data in step (1170), (1185), or (1200), step (
11280) to forcibly terminate the 5-second timer and return. Here, to forcefully terminate the 5 second timer,
As explained with reference to the flowchart in FIG. 5, if the remaining battery capacity is (A) or (B), the remaining battery capacity will not be displayed.
1185) or (+1200), the battery remaining amount display becomes a hindrance. However, when the remaining battery level is (C) or (D), the remaining battery capacity is also displayed to draw attention as described above.

Next, the details of creating the battery remaining amount data in step (155) in FIG. 5 will be explained with reference to FIGS. 7 and 8. In FIG. 7, the control unit (1) first determines the remaining battery level (1300) based on four preset remaining battery level levels: sufficient (A), present (B), low (C), It is determined whether it is either D).

If there is enough (A), proceed to step (1305) and create data for lighting up both segments (Segl9) and (Seg20) of the battery display mark on the external display section (8) in Fig. 8. . Here, the segment (
Seg19) is in the general shape of a battery, and Segment (Seg20) is in the form of a trapezoid disposed therein.

If it is determined in step (1300) that there is (B), only lighting data for the segment is created in step (11310). Therefore, the display at this time is an internal trapezoid [segment (Seg20)] as shown in Figure 8 (b).
] is not displayed. If it is determined in step (11300) that there is less (C), then in step (1315) blinking data for segment ) (Segl9) is created. Therefore, in this case, the segment (Se
gl9) flashes. Step (1300)
If it is determined that there is no D), proceed to step (#32
0), where the blinking data of the segment (Segl9) is created and all other display data is reset. Accordingly, other displays are turned off on the external display section (8) as shown in FIG.
Only 9) is displayed blinking. In addition, Figure 8 (c) and (d)
Although the blinking frequency of the segment (Segl9) is selected to be 2)+2, for example, it is not limited to this, and may be selected to any other appropriate frequency.

Next, the formation of the AP zone table display data 7 in step (8170) in FIG. 6 will be explained with reference to FIGS. 9 and 10. In Figure 9, first step (#400
) is the AP created in step (1165) in Figure 6.
The current zone is determined from the zone change data or the AF zone data when step (1165) is not passed, and if it is a spot zone, step (114) is performed.
05), and if wide, proceed to step (1410). As shown in Figure 10, the AP zone display is shown in the external display section (8) in segments (Sage) to (Sage).
The internal display section (9) is composed of segments (Seg15). Step (1
1405), among the segments (Segl) (
Seg2) (Seg3) (Segl5) is created, and in step (1410), the lighting data for the segment (Seg1) is created.
Create lighting data for (Seg2) (Seg4).

The reason why the internal display (9) provided in the viewfinder is not displayed when wide 8F is selected is that wide AF is a normal mode and does not require a warning. . On the other hand, the spot meter is in a special mode, and the internal display section (9) in the viewfinder lights up to notify you of this as a warning.

Regarding the external display section (8), a segment (Segl) as an outer frame and a segment (Seg2) indicating wide
lights up in both spot AF and wide AF, but
The segment (Seg3) lights up when it is spot, while the segment (SeH4) lights up when it is wide. As a result, a thin wide display mark (S
eH2) will be lit, and in the case of wide AF, a thick wide display mark (SeH2+Seg4) will be lit. In addition, for the wide display when using a wide AP, it may be configured not only by two segments (SeH2) and (SeH4), but also by one thick segment (not shown) that is a combination of them. However, in this embodiment, the wide AF zone display (SeH2
), the spot (SeH2) is emphasized and it becomes easier to associate the spot zone. During wide AP, an outline (18) corresponding to the segment (SeH2) may be displayed to indicate the spot zone.

Next, regarding the creation of drive mode display data in step (11185) in FIG.
1 and 12. First, step (15)
00), it is determined whether the current drive mode data is continuous shooting or single shooting, and if it is single shooting, step (15
05), in the case of quick shooting, the process proceeds to step (1510) to create lighting data for the segments forming the display mark. That is, in step (1505), the external display section (8)
The segment shown in Figure 12 regarding the display of (SeH5)
(SeH6) (SeH8) lighting data is created, and in step (1510) the segment (SeH5) (S
eH6) (SeH7) lighting data is created. Here, the letter S in segment (SeH8) represents Single.

According to the display of single shooting and continuous shooting shown in Fig. 12, some display marks are shared and both are displayed in the same space.
This has the advantage that space can be used effectively in a narrow display section such as a display section of a camera.

Next, specific examples of the creation of exposure mode display data in step (1200) in FIG. 6 will be described with reference to FIGS. 13 and 14. First, in step (#600), it is determined whether the current exposure mode data is P mode or M mode, and if it is P mode, step (#6
05), and in the M mode, the process proceeds to step (1610) to create lighting data for the segments constituting the display mark. That is, in step (11605), the lighting data of the segment (SeH9) forming the letter P shown in FIG. 14 is created, and in step (1610), the lighting data of the segment (SeglO) forming the character M is created. It is.

Next, regarding the metered manual display data shown in step (11140) in FIG.
It is shown and explained in FIG. In this embodiment, as can be seen from the following explanation, when looking at the display in the viewfinder, that is, the display on the internal display section (9), (AY switch (SaV)
Regardless of the operation of the up/down keys (16), consideration has been given to the direction of correction (however, the amount of correction cannot be determined).First, as shown in Figure 16, the under display mark is separated from the outer frame. It consists of a segment (SeH12) that includes an internal minus (-), and the display mark for over is the display mark for under (segment) (SeH12).
It is now configured with only H13) added. In addition, the mark indicating the up switch direction is composed of a segment (Segll), and the mark indicating the down switch direction is composed of a segment t- (SeH14).

In this embodiment, when changing the Tv value, that is, when the Av switch (SAV) is off, the up switch (S, . . .
When turned on, the Tv value increases, and the down switch (S4.
, ), the Tv value decreases. Also, when changing the Ay value, that is, when the Av switch (SAY) is on,
A method is adopted in which when the up switch (Sl1.) is turned on, the AV value decreases, and when the down switch (S, n) is turned on, the AV value increases.

Now, in FIG. 15, in step (1700), the control unit (1) first calculates the exposure calculation results based on the set values of the shutter speed (Tv) and aperture value (AV), the input brightness value (fh), and the film sensitivity. Based on the exposure calculation result based on the value (SV), it is determined whether the exposure value has no deviation and is appropriate, or whether the deviation is under or over, and in each case, steps (11725) and (1170) are performed.
5) Proceed to (1710), if appropriate, set segment (Segll) (Segll) in step (#725).
Create lighting data for H14). Therefore, two correction direction marks are displayed on the internal display section (9) as shown in FIG. 16. On the other hand, step (1705)
Now, create lighting data for segment (Seg12),
In step (1710), lighting data for segments (Seg12) and (Seg13) is created. After steps (1705) and (1710), the process proceeds to steps (1715 and 1720), respectively, and the Av switch (S
Determine whether AV) is ON or OFF and step (705)
When it is ON, it goes to step (1735), when it is OFF, it goes to step (1730,), and on the other hand, it goes to step (17
20) when ON, go to step (1730), OFF
If so, proceed to step (II735).

As a result, steps (1705) → (11715) → (
+1730), it becomes as shown in the column ■-■ in Figure 16, and the step (11705) → (11715
)→(1735), the display shown in the column ■-■ appears. On the other hand, step (+1710) → (1720)
→ (1735), the display will be as shown in the ■-■ column,
Step (1710) → (11720) → (I735)
In this case, the display shown in the column ■-■ will be displayed. As described above, according to this embodiment, since the correction direction is displayed in the viewfinder, it is possible to unconsciously change and correct the appropriate exposure value, which is convenient.

Finally, the creation of AP-related display data in step (1145) in FIG. 6 will be explained with reference to FIGS. 17 and 18. This data is displayed on the internal display section (9
). First, in step (1800) it is determined whether or not focus is achieved, and if in focus, a focus mark segment (Seg15) is created in step (1805).

This segment) (Seg15) is a dot of a predetermined size as shown in FIG. Next step (118
Proceed to step 10) to determine whether the subject is stationary (stationary object) or moving (moving object). In addition, if a moving object cannot be determined here, the same process as for a stationary object is performed, and as a result of the 0 judgment, if a stationary object or a moving object cannot be determined, a return is made.
If it is a moving object, proceed to step (1815), step (
1815) determines the value (N) of the 25Otls counter, returns when (N) is 5x (x is an integer greater than or equal to 0), and when it is 5x+1, proceeds to step (1820) and lights up the segment (Seg16). Create a display. This segment (Seg16) and the segment described later (
As shown in FIG. 18, Seg17) (Seg18) are patterned in a form that extends sequentially around the segment (Seg15) forming the focus mark.

If (N) is 5x+2 in step (11815), segment (Seg16) (
Seg17), and if it is 5x+3 or 5x+4, create a segment (Seg16) (
Seg17) (Seg18) lighting data is created. As a result, the 18th mark was obtained when in focus ■ and when out of focus ■.
A display as shown in the figure is displayed. At that time, 250 is
The display changes sequentially as ■→■→■→■→■, and after ■, it returns to ■.The state of ■ is displayed longer than other states, but There is no particular need to limit it to this. In this way, in this embodiment, regarding the display of in-focus and out-of-focus, the element of movement is incorporated to display the tracking state. Note that although the tracking display is performed using segments that are sequentially enlarged around the position where the focus mark segment (Seg15) exists, the present invention is not limited to this, and any other suitable movement display may be used. For example, move clockwise or counterclockwise around the focus mark (
A mark may also be provided.

The various displays explained above are collectively shown in Figs. 19 and 20. Here, Fig. 19 shows the display of the external display section (8), and Fig. 20 shows the display of the internal display section provided in the finder. (9) is shown.

When displaying the switching status of a function, it is often difficult to understand what has been selected if only the selected function is displayed, but in the present invention, only the selected first function is displayed. Instead, the non-selected second function is displayed thinly and simultaneously, which has the effect of improving the associativity of the function display and making it easier to understand what has been selected.
