1. An optical image stabilization module, comprising:
a first bracket, wherein the first bracket is of an annular structure and forms a hollow cavity;
an optical lens module arranged in the hollow cavity and fixed on the first bracket, wherein an optical axis of the optical lens module is parallel to a central axis of the hollow cavity;
a second bracket, wherein the second bracket is nested on an outer side of the first bracket;
a first connection assembly arranged between the first bracket and the second bracket, wherein the first bracket and the second bracket form a rotational connection about a first rotation axis by using the first connection assembly, and the first rotation axis is perpendicular to the optical axis;
a third bracket, wherein the third bracket is nested on an outer side of the second bracket; and
a second connection assembly arranged between the second bracket and the third bracket, wherein the second bracket and the third bracket form a rotational connection about a second rotation axis by using the second connection assembly, the second rotation axis is perpendicular to the optical axis and the first rotation axis, rotation of the optical lens module by first angle variation amounts about the first rotation axis is independently decoupled from rotation of the optical lens module by second angle variation amounts about the second rotation axis, both the first angle variation amounts and the second angle variation amounts are generated based upon measurement of posture data by a sensor, and a magnitude of a driving current is determined based on both the first angle variation amounts and the second angle variation amounts.
