Claims
- 1. A camera shake amplitude detecting device comprising:
- mechanical detection means for detecting a shake acceleration when a camera body is shaken; and
- mechanical shake calculation means for calculating a shake amplitude of the camera body based on the detection output of said mechanical detection means;
- said mechanical shake calculation means including:
- discrimination means for discriminating a time point of change from one to the other of a positive acceleration and a negative acceleration, based on the detection output of said mechanical detection means;
- velocity calculation means for calculating a velocity by integrating by time the acceleration detected by said mechanical detection means; and
- integration constant calculation means for calculating an integration constant to be used by said velocity calculation means, with the velocity at the time of discrimination by said discrimination means being set as a predetermined value.
- 2. A camera shake amplitude detecting device according to claim 1, wherein said predetermined value is zero.
- 3. A camera shake amplitude detecting device according to claim 1, wherein said mechanical shake calculation means further includes means for setting an offset value of said mechanical detection means to zero, and calculation means for using said detection output, said integration constant, and said offset value to integrate said velocity by time to calculate the camera shake amplitude.
