A method provides data synchronization between a sensor hub and an application processor, which contains at least the following steps: generating and adding a plurality of absolute time stamps in a sensor-data stream; and generating and adding a plurality of pieces of sensor data and a plurality of relative time stamps in the sensor-data stream between the moments of generating each two adjacent absolute time stamps, wherein each relative time stamp is associated with one piece of sensor data.

In the embodiments of the disclosure, a target signal which is a signal of a part used for subsequent processing is acquired from signals output from a device with higher accuracy. A control apparatus includes a first acquisition part which acquires a first signal of a time series output from a first device, a recording part which records a part of the first signal acquired by the first acquisition part, and a determination part which determines a timing at which the recording part records the first signal based on a preset predetermined condition.
