Electronic device and focusing method

A focusing method, applied to an electronic device, the electronic device comprising at least two cameras, each of the at least two cameras being provided with a phase difference (PD) point pair set, the method comprising:

• obtaining at least two target parameters, wherein each target parameter is a phase parameter obtained by using the PD point pair set on one camera, an angle value between directions of straight lines in which the PD point pair sets on every two cameras in the at least two cameras are located is within a first preset angle range;
• determining at least two target phase differences according to the at least two target parameters, wherein each target phase difference is a phase difference in a direction corresponding to one camera;
• and
• controlling the at least two cameras to focus according to the at least two target phase differences.

An electronic device, comprising a processor, a memory, and a computer program stored in the memory and executable on the processor, wherein the computer program, when executed by the processor, causes the electronic device to perform:

• obtaining at least two target parameters, wherein each target parameter is a phase parameter obtained by using a phase difference (PD) point pair set on one camera, an angle value between directions of straight lines in which the PD point pair sets on every two cameras in the at least two cameras are located is within a first preset angle range;
• determining at least two target phase differences according to the at least two target parameters, wherein each target phase difference is a phase difference in a direction corresponding to one camera;
• and
• controlling the at least two cameras to focus according to the at least two target phase differences.
