Title:
VIBRATION DETECTING DEVICE
Document Type and Number:
Japanese Patent JP3899262
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a vibration detecting device capable of always detecting the amount of the shake of a photographing device with high accuracy.
SOLUTION: In this vibration detecting device, angular velocity sensors 5, 6 are positioned respectively in accordance with an X axis and a Y axis in a photographing device and they output respectively vibration signals corresponding to the shake of the photographing device around corresponding X axis and Y axis. An amplifying part 8 having a plurality of amplifier circuits amplifies respectively the respective vibration signals output by the angular velocity sensors 5, 6. Moreover, the amplification factor of the amplifier circuit corresponding to the Y axis is set to a value larger than that of the amplifier circuit corresponding to the X axis by noticing that the X axis has a tendency to generate larger shake as compared to the Y axis.
