M25にバックアップ用のバッテリーは不用である。In FIG. 17, when the power is turned on, a pulse integrated by a resistor R1 and a capacitor C1 is input to the one-shot multivibrator 32, and after waveform shaping and widening the pulse width, is input to the CPU 17 from the OR gate 33. Further, a signal from the reset switch 16 is input to the other input terminal of the OR gate 33. Therefore, when the power is turned on and when the reset switch 16 is operated, the CPU 17 performs the same operation as in the embodiment shown in FIG. In this case, since the above operation is performed when the power is turned on, the RA
The M25 does not require a backup battery.

場合に適した実施例を説明する。Next, after adjusting the sizes of the left and right images for each change in zoom ratio by operating the zoom button of the twin-lens stereoscopic camera using the above-mentioned method, the effects of changes in temperature and humidity (for example, when shooting in a hot and humid area) are adjusted. (after shooting in low-temperature regions, etc.)
An embodiment suitable for a case where there is a possibility that the mechanical adjustment value may be deviated due to the influence of weather conditions such as strong winds, or movement of the shooting location due to the shooting scene, etc. will be described.

に示したカメラ位置の調整手段を用いる。First, as a method of matching the sizes of the left and right images on the wide-angle side and the telephoto side of the zoom lens, the mechanism adjustment means shown in Fig. 1 is used, and the same change in the size of the left and right images is measured using the operation button. As a method of automatic adjustment, the automatic adjustment means shown in Fig.
If the mechanical setting values shown in Figure 1 above become incorrect due to the influence of strong winds, movement of the shooting location, etc., readjusting the camera's zoom ring at the wide-angle end and telephoto end will require adjustment parts due to the nature of the zoom ring. The size becomes smaller and adjustment becomes difficult and time consuming. For this reason, in this embodiment, in addition to the mechanism adjustment means shown in FIG. 1, a camera position adjustment means shown in FIG. 2, which can move the camera position of one camera side or both cameras back and forth, is used. .
このようにすれば、第1図に示した機構設定値が狂った

Inaccuracies and variations in the above adjustment can be easily corrected.

立体撮影が可能である。<Effects of the Invention> As described above, according to the present invention, in a twin-lens stereoscopic camera, the left and right zoom lenses can be linked together and the sizes of the left and right images can be automatically adjusted every time the zoom ratio is changed by operating the zoom button. , the operability of the 3D camera has been greatly improved, the shooting time has been shortened, and the shooting cost has been reduced.In addition, the design has been designed to absorb variations in weather conditions, environmental changes, and settings. A wide variety of 3D photography is possible, regardless of location, scene, or shooting conditions, such as 3D photography of a climb to the summit of Mont Blanc, or next week a 3D photography of a cruise in the Aegean Sea.
