FIG. 6 is a flow chart showing the control procedure of the display operation of the display device 2 by the control device 1. When the release button of the camera is half-pressed and the half-press switch 8 is turned on, the control device 1 starts the illustrated process. First, in step S1, the object distance is measured by the distance measuring device 3, and the result is stored in the built-in memory. In the following step S2, the photometry device 4 measures the field. In step S3, the shutter speed that gives a proper exposure is calculated from the photometric result of the subject and the aperture setting value set by the aperture setting device 5,
Memorize the result.

In the next step S4, the shutter speed calculated by the display device 2 is displayed. In step S5, a built-in timer is activated to continue displaying the shutter speed for a predetermined time. In the next step S6, the subject distance detected in step S1 is displayed on the display device 2 as a shooting distance. In a succeeding step S7, it is determined whether or not the half-push switch 8 is on. If it is on, the process proceeds to a step S8 to determine whether or not the release switch 9 is on. If the release switch 9 is on, the process proceeds to step S9. In step S9, the photographic lens is driven to a position according to the subject distance detected by the photographic lens drive device 6, and the aperture and shutter are controlled by the aperture value set by the exposure control device 7 and the calculated shutter speed. Exposure is performed and the post-processing is completed. When it is determined in step S7 that the halfway press switch 8 is off, the process is terminated without performing exposure. When it is determined in step S8 that the release switch 9 is off, the timer is started in step S10, the display of the shooting distance is continued for a predetermined time, and then the process returns to step S4.

FIG. 3 shows the display operation of the display body 20 by the above-mentioned processing. In this example, the calculated shutter speed was 1/8 second and the shooting distance was about 1 m.
First, the numerical index 200a and a part of the graphic index 210b are turned on at the same time to display the shutter speed of 1/8 second, and then the entire graphic index 210b is turned on individually to display that the shooting distance is about 1 m. It Then, as long as the half-push switch 8 is on and the release switch 9 is off, the display of both is alternately repeated.

As is apparent from the above, in the present embodiment, the numerical indexes 200a to 200c of the second hour index group 200 and the graphic index 2 of the distance index group 210 for displaying the shutter speed.
10a to 210e are arranged in a mixed manner on the same column, and one of the numerical indexes 200a to 200c and a partial segment of any one of the graphic indexes 210a to 210e adjacent to the numerical indexes 200a to 200e are turned on at the same time. Since the shutter speed omitted in the index group 200 is displayed, the second hour index group 20 is displayed.
Since it is not necessary to provide a numerical index of 0 for each stage, the space required for the display body 20 is reduced. Numerical index 200a
-200c and graphic indices 210a-210 adjacent thereto
Since it is possible to easily read the intermediate shutter speed by simultaneously turning on a part of e, the visibility of the display device can be kept good as compared with the case where a part of the shutter speed display is simply omitted. In the above processing, when the calculated shutter speed can be independently displayed by any one of the numerical indexes 200a to 200c, the shooting distance is displayed by the distance index group 210 and the shutter speed is displayed by the second index group 200. May be performed simultaneously. In Figure 4, shutter speed 1 /
Numerical index 200b indicating 30 seconds and shooting distance 1.5-2
An example is shown in which the graphic index 210c indicating m is turned on at the same time.

In this embodiment, numerical indicators 200a to 200c for displaying the shutter speed and an index 210a for displaying the photographing distance are shown.
.About.210e are mixed, but the present invention is not limited to such an example, and combinations of indexes corresponding to various kinds of information are possible. The present invention can be applied not only to a device that displays shooting information by the display 20 in the finder but also to various display devices such as a device that displays shooting information using a liquid crystal panel on the top surface of the camera. Further, although only some of the segments of the figure indicators 210a to 210e of the distance information are turned on at the same time as the numerical indicators 200a to 200c, all the segments constituting any one of the figure indicators 210a to 210e are turned on at the same time. An intermediate shutter speed may be displayed. However, when only a part of the segments of the graphic indexes 210a to 210e are simultaneously illuminated with the numerical indexes 200a to 200c as in the embodiment, the intermediate shutter speed display is misread as simultaneous display of the shooting distance and the shutter speed. There is no danger of

In the correspondence between the above embodiment and the claims,
The second index group 200 constitutes an exposure index group, the distance index group 210 constitutes a mark group, and the graphic indices 210a to 210e constitute respective marks of the mark group. The exposure index group and the marks of the mark group do not necessarily have to be mixed on a straight line, and may be arranged in an arc shape, for example.

[0020]

As described above, according to the present invention, the numerical index of the exposure index group and the mark of the mark group for displaying the information different from the exposure information are mixed on the same column, and the numerical index and Since a part of the exposure information is displayed simultaneously with the adjacent mark, it is possible to efficiently display a plurality of information in a limited space by omitting a part of the numerical index for exposure information. Sexual deterioration can be minimized.
