Abstract
The inertial sensor device is an inertial sensor device including a plurality of inertial measurement modules, and includes: a clocking unit; a storage unit configured to store detection data from each of the plurality of inertial measurement modules in association with a time point of the clocking unit; and a synthesis processing unit configured to calculate interpolation data at a predetermined time point based on the detection data from each of the plurality of inertial measurement modules at at least two time points, and synthesize, using the interpolation data for each of the plurality of inertial measurement modules, output data at the predetermined time point.

An inertial sensor device including a plurality of inertial measurement modules, the inertial sensor device comprising:
- a clocking unit;
- a storage unit configured to store detection data from each of the plurality of inertial measurement modules in association with a time point of the clocking unit;
- and
- a synthesis processing unit configured to calculate detection data at a predetermined time point, using a first time point when each of the multiple inertial measurement modules detects first detection data and a second time point when each of the multiple inertial measurement modules detects second detection data, by adding an error change amount obtained by multiplying a slope of the first detection data and the second detection data by a difference between the first time point and the second time point to the first detection data, and to synthesize detection data at the predetermined time point for each of the multiple inertial measurement modules.
