Power supplying method and apparatus

A camera module, comprising:

• a detection pin group, configured to connect to a power supplying apparatus and identify a type of the camera module;
• a camera unit, configured to perform imaging;
• and
• at least three power supply units, connected to the camera unit and the power supplying apparatus, and configured to receive power supplied by the power supplying apparatus to the camera unit.

A power supplying method, comprising:

• generating a recognition signal according to a detected detection signal on a detection pin group of a camera module, wherein the detection pin group of the camera module is configured to identify a type of the camera module;
• recognizing the type of the camera module according to the recognition signal, to determine power supply information corresponding to the type of the camera module, wherein the power supply information comprises a power supply time sequence of at least three power supply units and a power supply voltage of each power supply unit among the at least three power supply units;
• and
• controlling the power supply time sequence of the at least three power supply units and the power supply voltage of each of the power supply units according to the power supply information, so that the at least three power supply units supply power to the camera module.
