Abstract

A shake detecting sensor includes: a plurality of shake detecting sensors that detects a shake; and an adder circuit that adds shake signals output from the plurality of shake detecting sensors. A signal added by the adder circuit is output as a shake signal output from one sensor.

Claims

1. A shake detecting sensor comprising:

a plurality of shake detecting sensors that detects a shake; and

an adder circuit that adds shake signals output from the plurality of shake detecting sensors,

wherein a signal added by the adder circuit is output as a shake signal output from one sensor.

2. The shake detecting sensor according to claim 1,

wherein the plurality of shake detecting sensors, or the plurality of shake detecting sensors and the adder circuit are incorporated into one package.

3. The shake detecting sensor according to claim 1,

wherein each of the plurality of shake detecting sensors is a gyro sensor.

4. The shake detecting sensor according to claim 2,

wherein each of the plurality of shake detecting sensors is a gyro sensor.

5. An image blur correcting device comprising:

a shake detecting unit that outputs a shake signal corresponding to a shake which occurs in an optical system;

an image displacement unit that displaces an image formed by the optical system on an imaging surface; and

an image blur correcting unit that removes image blur caused by the shake occurring in the optical system using the image displacement unit, based on the shake signal,

wherein the shake detecting unit includes;

a plurality of shake detecting sensors that detects the shake; and

an adder circuit that adds shake signals output from the plurality of shake detecting sensors, and

wherein a signal added by the adder circuit is output as a shake signal output from one sensor.

6. The image blur correcting device according to claim 5,

wherein the plurality of shake detecting sensors, or the plurality of shake detecting sensors and the adder circuit are incorporated into one package.

7. The image blur correcting device according to claim 5,

wherein each of the plurality of shake detecting sensors is a gyro sensor.

8. The image blur correcting device according to claim 6,

wherein each of the plurality of shake detecting sensors is a gyro sensor.
