6, when acceleration is applied, all piezoresistors R X1
ＲR X4 , R Y1 ＲR Y4 , and R Z1 ＲR Z4 receive a tensile stress, and the resistance values of the piezo resistors R X1 and R X3 decrease, and the resistance values of the other piezo resistors increase. As a result, an output is obtained only from the bridge that detects the acceleration in the X-axis direction,
The output of the bridge that detects the axial acceleration is zero.
Similarly, when acceleration is applied only from the Y-axis direction or the Z-axis direction, only the output of the bridge that detects the acceleration in the Y-axis direction or the Z-axis direction is obtained, and the outputs of the other two bridges become zero. . Therefore, the acceleration sensor 46 can independently detect accelerations in three axial directions.

It is possible to distinguish between vibration when the camera is shaken positively and vibration normally applied to the camera. When the camera is stored in a waterproof pack or the like and used underwater, the camera cannot be quickly shaken underwater, so it is necessary to separately switch the camera in the underwater mode, thereby lowering the thresholds V U and V L.
