Return to step 2 and perform re-ranging and display. Closer than the specified distance
In this case, the process proceeds to the next step S11. In step S11
Indicates that the self-timer starts operating and the self LED blinks
Starts (S11). In step S12, the self-operation
The time from the start is counted and compared with a predetermined time (S
12). If it is shorter than the predetermined time, this step S12 is performed.
Is repeated again. After a predetermined time, the self LED
The blinking is stopped, and the process proceeds to the next step S13. In steps S13 to S15, first,
The current zoom obtained from the output of the zoom position detection circuit 13
The position and the position obtained in step S4 or step S8 are obtained.
Focusing lens based on measured distance measurement result (LDATA)
The LD motor of (LD) is driven (S13). Next,
The shutter drive circuit 10 controls a well-known shutter mechanism.
To perform exposure (S14). Then, the feed motor drive circuit
By driving the road 12 and winding up one frame, a series of
The photographing operation ends (S15). After that, prepare for the next shot
Then, the process returns to step S1, and the same sequence is repeated.
And repeat. As described above, in the first embodiment, the distance measurement result
Display means (that is, a distance measurement result display device)
114) is mounted on the front of the camera,
Notify the subject of the ranging result at the ranging point to be measured
Shooting so that the photographer himself becomes the subject.
Even in the case of shadow scenes,
Check the distance measurement result display device 114 to see if it is correct
And the position can be correctly determined. (Modification 1) The first embodiment described above is as follows.
The embodiment may be modified as follows. For example, in the first embodiment,

I can wait. In the above embodiment, the display for displaying the distance measurement result
Although the device is separate, for example, the first embodiment described above
The self LED used in the above may be used. Also, for example,
7, in step S210, the distance measurement is performed.
Displays the result, but instead of displaying the distance measurement result,
Change the blinking cycle of the LED to notify the subject
May be. Or at the same time, the remote control signal is received
You may also indicate that there is no such thing. (Other Modifications) First Embodiment and Second Embodiment
The embodiment may be modified in other ways. For example, on
In each embodiment, the distance measurement result and the EEPR
Although the comparison with the predetermined distance stored in the OM is performed,
Switching means for switching this predetermined distance is separately installed
May be. In this case, the distance from the camera to the subject
By inputting by the photographer (that is, the subject itself),
The position of the subject can be adjusted more accurately. Ma
Also, the case where the distance measuring point is 3 points was explained.
However, the same operation is performed even if there are four or more ranging points.
It goes without saying that this can be explained. In addition, books

Claims (1)

  1. Claims 1. A distance measuring means having a plurality of distance measuring points, and a distance measuring point selecting means for selecting a desired distance measuring point from the plurality of distance measuring points. A camera comprising: a display means for displaying a distance measurement result at a selected distance measurement point; 2. A distance measuring means having a plurality of distance measuring points, a display means for displaying a distance measuring result at a selected distance measuring point, and a self mode switching means for switching between a self-timer mode and a normal photographing mode. In the camera, the display means selects the self-timer mode,
    The camera operates when the distance measurement result at the distance measurement point is longer than a predetermined distance. 3. The camera according to claim 2, wherein said display means is also used as a self LED. 4. A distance measuring means having a plurality of distance measuring points, a distance measuring point selecting means for selecting a desired distance measuring point from the plurality of distance measuring points, and a remote control receiving means. A camera, wherein a remote control signal is not received when a distance measurement result at a selected distance measurement point is longer than a predetermined distance.
