Abstract
Official abstract text for this publication.
The apparatus of the invention is characterized by executing first integration operation for time-integrating the first acceleration to calculate a first velocity, second integration operation for time-integrating the first velocity to calculate an amount of movement in the first axial direction, estimation operation for calculating an estimated first velocity in the first axial direction based on a first velocity change found by time integration of the first acceleration from a first timing at which the third angular velocity becomes zero to a second timing at which the third angular velocity again becomes zero, the second angular velocity at the first timing, and the second angular velocity at the second timing, and update operation for updating the first velocity calculated in the first integration operation to the estimated first velocity estimated in the estimation operation.
First claim
Opening claim text (preview).
What is claimed is: 1. An amount-of-shake sensing apparatus, comprising: a first acceleration sensor which detects a first acceleration in a direction of a first axis, a second angular velocity sensor which detects a second angular velocity around a second axis that is orthogonal to the first axis, a third angular velocity sensor which detects a third angular velocity around a third axis that is orthogonal to the first axis and the second axis, and a movement calculator whic…
