What is claimed is: 1. 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 interpolation data at a predetermined time point based on the detection data from each of the plurality of inertial measurement modules of 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. 2. The inertial sensor device according to claim 1 , wherein the synthesis processing unit calculates the interpolation data by interpolating the detection data at n+1 or more time points using an n-th order function. 3. The inertial sensor device according to claim 1 , wherein the synthesis processing unit calculates the interpolation data by interpolating the detection data at the two time points by a linear function. 4. The inertial sensor device according to claim 3 , wherein the predetermined time point is a time point after the two time points. 5. The inertial sensor device according to claim 1 , wherein the synthesis processing unit calculates the interpolation data by interpolating the detection data at three time points by a quadratic function. 6. An inertial sensor device including a plurality of inertial measurement modules having a first inertial measurement module, 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 interpolation data at a predetermined time point based on the detection data from the first inertial measurement module of at least two time points, and synthesize, using the interpolation data for the first inertial measurement module, output data at the predetermined time point.
