Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera, and more particularly, to displaying a difference between an exposure set by exposure compensation of a camera and an exposure manual setting and an appropriate exposure.

[0002]

2. Description of the Related Art Conventionally, when setting exposure compensation or manual exposure, as a means for confirming the difference between the set exposure and the proper exposure, the difference is indicated by a numerical value, or the numerical value indicating the difference is indicated in advance as an index. Every time, a mark was shown on the numerical value indicating the difference.

FIG. 7 shows a conventional example of a liquid crystal display unit which has two minimum correction widths for exposure correction, that is, 1/3 step and 1/2 step.
The dots between the numbers shown in every other step of the index are in 1/3 step increments for smaller ones and 1/2 step increments for larger ones. In FIG. 4, the -1/3 stage correction is shown.

As described above, in order to display the minimum correction width corresponding to two steps of 1/3 step and 1/2 step, the dot correction is made more than when the minimum correction width of exposure correction is only 1/3 step. We had to increase the number and add a display element for displaying the mark.

[0005]

However, in the means for confirming the difference between the above-mentioned set exposure and the proper exposure, the difference between the proper exposure regardless of whether the numerical value is displayed or the mark is used. However, there is a problem in terms of cost and space. An object of the camera of the present invention is to provide a photographer with information at the time of exposure compensation and manual exposure setting without increasing the number of display elements.

[0006]

According to a first aspect of the present invention, there is provided a unit display section having a plurality of unit display sections for each preset unit and the unit display section. A display unit having an index display unit corresponding to
A display mode selection unit that has a first display mode in which display is performed according to the settings as in the unit display section, and selects a second display mode in which display is performed in a unit different from the unit of the unit display section, and a set exposure value. And an appropriate exposure value, and a display control means for calculating the deviation amount and displaying the deviation amount on the index display section of the display means based on the mode selected by the display mode selection means. In a camera having a manual exposure mode in which the exposure value can be set by the operation of, when the second display mode is selected by the display mode selection unit, the display control unit determines the shift amount of the display unit. When it is between the set values shown on the unit display section, a plurality of index display sections in between are displayed integrally.

With this configuration, even in the second display mode, by displaying a plurality of index display units as one unit instead of one, it is possible to distinguish from the first display mode, and particularly the display element of the display means. The display in the first display mode and the second display mode can be performed without increasing the number of items.

According to a second aspect of the present invention, there is provided an integrated display mode.
As described in claim 3, simultaneously display a plurality of index display parts, as described in claim 3, alternately display a plurality of index display parts, as described in claim 4, a plurality of index display The parts can be displayed in a blinking manner, and by displaying the two index display parts, these display modes can be made possible with the minimum display.

Further, the unit of the unit display section of the display means is set to 1/3 stage as described in claim 6, so that the number of display elements does not need to be increased with high precision and even when the display mode is changed. And, as described in claim 7, the number of display elements is small and the visibility can be improved by making the number of steps to be 1/2, and as described in claim 8, the number of display elements is set to be one step.
Numerical values can be displayed with a small number of display elements.

According to a ninth aspect of the present invention, in any one of the first to eighth aspects, the display means is a display means for displaying a shift range of the number of exposure steps in a shooting mode in which the exposure is shifted by a predetermined number of steps for each shooting. The camera is characterized in that the index display section is also used according to the number of steps.

With this structure, the number of steps in the exposure range can be clearly displayed even in the so-called AEB mode.

In the case of three stages, the marks at the positions of +1/3 and +2/3 are turned on at the same time, which indicates that the correction value is +1/2.

Similarly, when the dial is further rotated to the right by one click, the mark moves to the position indicating the index 1 and the display shown in (7) of FIG. 1 is obtained, and the correction value becomes +1 step. Even if the minimum correction width of the exposure correction is two, that is, 1/3 step and 1/2 step, the minimum correction width is 1/2 step without increasing the number of display elements whose minimum correction width is 1/3.

[Embodiment 2] Another embodiment of exposure compensation is shown in FIG.
It will be described based on. The specific configuration of the electric control block of the camera of this embodiment is the same as that shown in FIG.

As in the first embodiment, when exposure compensation is applied,
First, an exposure compensation setting mode is entered by pressing an exposure compensation button (not shown). After entering the exposure compensation mode, rotate the dial to the right to make a correction to the + side and rotate the dial to the left to make a correction to set the correction value.

In FIG. 2A, the minimum correction width of the exposure correction is 1
It is a liquid crystal display unit set to / 2 steps. The index indicating the exposure correction value is a numerical value for each step, and a dot is printed for each half step between them. The mark indicates 0 of the index, and indicates that the exposure correction is 0, that is, the exposure correction is not applied.

When entering the exposure compensation mode in which the minimum compensation width of the exposure compensation is set to 1/3 step, when the minimum compensation width is set to 1/2 step, the dial is used to correct to the + side. To correct to the right or to the minus side, rotate the dial to the left to set the correction value.

In (4) of FIG. 2, the mark indicates 0 as an index, indicating that the exposure correction is 0, that is, the exposure correction is not applied. Here, when the dial is rotated one click to the right, 0 and + as shown in (5) of FIG.
The mark at the position indicating 1/2 step is turned on at the same time, which indicates that the correction value is +1/3 step. Similarly, if you rotate the dial to the right by another click,
As shown in (6) of FIG. 2, the marks at the positions indicating 1/2 stage and +1 stage are turned on at the same time, so that the correction value is +2.
It means that it has three steps. Further, when the dial is further rotated to the right by one click, the mark moves to the position indicating the index 1 and the display shown in (7) of FIG. 2 is obtained, and the correction value becomes +1 step. In this way, it is possible to display the exposure correction value with a finer precision than the display precision.

[Embodiment 3] An example in which the present invention is carried out by manually setting the exposure, particularly by giving priority to the shutter will be described with reference to FIG. The manual exposure setting here refers to an exposure setting in which the photographer arbitrarily sets either one or both of the shutter speed and the aperture. The specific configuration of the electric control block of the camera of this embodiment is the same as that shown in FIG.

When setting exposure with shutter priority,
First, the exposure mode setting mode is entered by pressing an exposure mode setting button (not shown). When the dial is turned while pressing the exposure mode setting button (not shown), the exposure modes such as shutter priority mode, aperture priority mode, shutter / aperture manual setting mode, program mode, bulb (BULB), and depth are displayed. The order of the exposure modes displayed varies depending on whether you turn the dial clockwise or counterclockwise.

When the shutter priority mode is displayed, the exposure mode setting button (not shown) that has been pressed is released. As a result, the exposure mode is set to the shutter priority mode.
Next, the shutter speed is set. Turning the dial to the right displays the shutter speed in the high speed direction, and turning it to the left displays the shutter speed in the low speed side. At the desired shutter speed, stop the dial. At this time, the internal viewfinder display shows the microcomputer 1 depending on the set shutter speed.
The amount of deviation between the aperture value calculated by and the proper exposure is displayed. (1) of FIG. 3 shows shutter speed 1/250
This is the display when set to seconds. The numeral 250 in the 7-segment display in (1) of FIG. 3 indicates 1/250 second of the set shutter speed, and the numeral 2.5 in the 7-segment display is the aperture value F2 calculated by the microcomputer 1. .5 is shown. The amount of deviation from the proper exposure is indicated by the mark pointing to the index displayed under the viewfinder. 0 is the proper exposure in the center of the index, and a small dot represents a one-step shift. The right side of the viewfinder is in the + direction and the left side is in the-direction. Since the mark indicates 0 at the center, the exposure is proper.

Next, turn the dial to set the shutter speed to 1
The display when / 320 seconds is set is (2) in FIG.
Since the open aperture value of the lens (not shown) attached to the camera was F1.8, the aperture stopped at F1.8. The mark shows both the center 0 of the index on the right of the viewfinder and the dot one below. The dot one lower in the center indicates -1/2 step from the proper exposure, and both 0 in the center point the mark to indicate -1/3 step between the appropriate -1/2 steps. . Turn the dial again to set the shutter speed to 1
/ 2000 is displayed as (3) in FIG.
Since the exposure value is below -2 steps, a mark indicating below the index display value is turned on to notify that the exposure is below -2 steps with respect to the proper exposure.

Although the liquid crystal is used to display the correction value for the exposure correction in this embodiment, the present invention can be applied to the case where a display element such as an LED or a lamp is used. Also, the indicators and marks that show the amount of deviation from the proper exposure are 1, 1/2,
It is needless to say that the minimum unit is 1/3 step, and it goes without saying that it may be changed depending on the required accuracy, the number of usable display elements and the like.

Next, the operation of this embodiment will be described with reference to the flow chart shown in FIG.

# 301; Determination of Presence / Absence of Dial Input If there is a dial input, the process proceeds to # 302, and if there is no dial input, proceeds to the end of # 308.

# 302: Setting of shutter speed Shutter speed = number of dial inputs * 1/3 step (change amount from current value) The setting direction is to the high speed side and the left direction when the dial is rotated to the right. When it is rotated, it is set to the low speed side, and each corresponds to 1 click of the dial = 1/3 step.

# 303: Confirm the difference from the proper exposure. If the exposure obtained by the shutter speed set in # 302 is ± 2 steps or more from the proper exposure, go to the process of # 304 and go to the proper exposure. If it is within ± 2 steps, the process proceeds to # 305.

# 304: If the dew obtained by the shutter time set in # 302 is +2 steps or more relative to the proper exposure, a + mark is displayed, and if -2 steps or more, a-mark is displayed. .

# 305: Determination of the currently set minimum correction width of the exposure correction If the exposure correction value = 1/3 step, the process proceeds to # 307, and if the minimum correction width = 1/2 step, the process proceeds to # 306.

# 306: Display of difference from proper exposure when minimum correction width = 1/2 step One mark corresponding to each 1/2 step is turned on.

# 307: Display of the difference from the proper exposure when the minimum correction width = 1/3 steps. Two marks sandwiching the set exposure correction value are lit at the same time.

The mark indicating +2/3 stage is turned off, the mark indicating +1/3 stage is turned on again, and the mark indicating +1/3 stage and +1/2 stage is alternately turned on by turning off the mark. The exposure correction value is +1/2 step.

Similarly, when the dial is rotated to the right by another click, the mark moves to the position indicating the index 1 and the display shown in (4) of FIG. 4 is obtained, and the correction value becomes +1 step. Even if the minimum correction width of the exposure correction is two, that is, 1/3 step and 1/2 step, the minimum correction width is 1/2 step without increasing the number of display elements whose minimum correction width is 1/3.

The mark indicates 0 of the index, and the AEB shift amount is 0, that is, the AEB is not set.

Here, when the dial is rotated rightward by one click, the mark is +1/3 steps, +2/3 steps and -1 in addition to the 0 position of the index, as shown in (2) of FIG. / 3
Stages and -2/3 stages are shown simultaneously. The 7-segment display is
The current AEB setting is displayed numerically. This display shows a proper exposure of 0 as an index, +1/2 step over +1/3 step and +2/3 step turned on at the same time, and -1 /
It shows that AEB photography of -1/2 step under, which is shown by simultaneously lighting the 3rd step and the -2/3 step, is performed. 0.5 in the 7-segment display indicates that the set value of AEB is 0.5 step width.

When the dial is further rotated rightward by one click, the mark is 0, + as shown in (3) of FIG.
The 1st stage and the -1st stage are shown, and the 7 segment is displayed as 1.0, indicating that the set value of the AEB is one stage wide.

As described above, even when a numerical value that does not exist in the index is displayed on the same index, by displaying a plurality of indexes by the mark, it is possible to display intelligibly without increasing the number of display elements.

Next, the operation of this embodiment will be described with reference to the flowchart shown in FIG.

# 601; Determination of Presence / Absence of Dial Input If there is a dial input, the process proceeds to # 602. If there is no dial input, the process proceeds to the end of # 607.

# 602: Judgment of the minimum width of the exposure shift amount that is currently set. If the minimum width = 1/3 steps, the process proceeds to # 603, and the minimum width = 1 /.
If there are two stages, the process proceeds to # 605.

# 603: Exposure shift amount = 1 / 3-step setting Exposure shift amount = Number of dial inputs * 1 / 3-step Rotate the dial clockwise to increase the exposure shift amount, and rotate it to the left The exposure shift amount is set to decrease. In each case, 1 click on the dial = 1/3
Corresponds to a step.

# 604: Display of exposure shift amount A mark corresponding to the reference 0 and the exposure shift amount is turned on.

# 605: Exposure shift amount = setting in 1/2 step Exposure shift amount = number of dial inputs * 1/2 step Rotate the dial to the right to increase the exposure shift amount and to the left. The exposure shift amount is set to decrease. 1 click of dial = 1/2
Corresponds to a step.

# 606: Display of exposure shift amount The display state is changed according to the fraction of the exposure shift amount set in # 605.

The mark corresponding to the standard 0 and the exposure shift amount is turned on in the 1/1 step (exposure shift amount = ± 1, ± 2).

1/3 step (exposure shift amount = ± 1/2, ± 1
1/2) Simultaneously turn on the two marks sandwiching the reference 0 and the exposure shift amount.

# 607: AEB setting mode ends.
