Data collection device, data collection system, and electronic image stabilization device

An electronic image stabilization device, comprising:

• a data collection device, comprising:
• a timer, configured to generate timestamp data;
• a control module, configured to, in response to receiving a pre-set input signal, generate a data obtaining command and obtain the timestamp data from the timer;
• a communication module, configured to, in response to the data obtaining command, obtain Micro-Electro-Mechanical system (MEMS) data from a MEMS sensor;
• and a packing module, configured to pack the MEMS data and the timestamp data into a data packet;
• wherein the data collection device further comprises:
• a time offset register, configured to store a pre-set time offset, and the packing module is configured to read the time offset from the time offset register, correct the timestamp data using the time offset, and combine the MEMS data and the corrected timestamp data into the data packet;
• a digital image stabilization module, configured to perform digital image stabilization processing on a digital image using the data packet provided by the data collection device;
• wherein the control module comprises a dedicated hardware control module independent of a multi-functional control unit, the dedicated hardware control module is configured to receive an interrupt signal of a gyroscope or a trigger signal of a timer, acquire the MEMS data from the MEMS sensor, and obtain the timestamp data from the timer;
• wherein the time offset is an empirical value with respect to the MEMS sensor.
