Information capturing device and operating method thereof, and control method of positioning unit

An information capturing device, comprising:

• a positioning unit, tracking and acquiring a plurality of satellite signals, and calculating positioning data and a moving speed according to the plurality of satellite signals, wherein the positioning unit is configured to switch between a first operation mode and a second operation mode, wherein in the first operation mode, the positioning unit updates, according to a first cycle, positioning data generated by the positioning unit in the second operation mode, the positioning unit updates, according to a second cycle longer than the first cycle, the positioning data generated by the positioning unit;
• an audiovisual recording unit;
• and
• a control unit, coupled to the positioning unit and the audiovisual recording unit, activating the audiovisual recording unit of the information capturing device to perform audiovisual recording, and when the recording operation of the audiovisual recording unit is activated, concurrently controlling the positioning unit to enter the first operation mode;
• wherein, during the audiovisual recording, the control unit reads the moving speed from the positioning unit, and when the moving speed is less than or equal to the first threshold, the control unit controls the positioning unit to switch to the second operation mode.

A control method of an operation mode of a positioning unit, comprising:

• in an activation process, controlling the positioning unit to enter a first operation mode, wherein the positioning unit is configured to switch between the first operation mode and a second operation mode, wherein in the first operation mode, the positioning unit updates, according to a first cycle, positioning data generated by the positioning unit in the second operation mode, the positioning unit updates, according to a second cycle longer than the first cycle, the positioning data generated by the positioning unit;
• reading a moving speed from a positioning unit;
• comparing the moving speed with a first threshold;
• and
• when the moving speed is less than or equal to the first threshold, controlling the positioning unit to switch from the first operation mode to the second operation mode.
