and controlling the gimbal to enter the stabilization mode includes controlling the yaw shaft frame, the roll shaft frame, and the pitch shaft frame for stabilization. ### Claim 3 (depends on 1) The imaging method of claim 1, wherein the second exposure duration is manually set or adjusted by a user. ### Claim 4 (depends on 1) The imaging method of claim 1, further comprising: detecting the amount of incident light; and determining the second exposure duration according to the amount of incident light. ### Claim 5 (depends on 1) The imaging method of claim 1, wherein: the imaging device is configured to perform imaging at a first sensitivity in response to the amount of incident light being greater than the preset value; and controlling the imaging device to perform imaging with the second exposure duration includes controlling the imaging device to perform imaging with the second exposure duration at a second sensitivity lower than the first sensitivity. ### Claim 6 (depends on 5) The imaging method of claim 5, wherein the second sensitivity is negatively correlated with the second exposure duration. ### Claim 7 (depends on 1) The imaging method of claim 1, wherein the second exposure duration is within a range of a locking duration of the gimbal. ### Claim 8 (depends on 7) The imaging method of claim 7, wherein a start time of the second exposure duration is same as a start time of the locking duration, and an end time of the second exposure duration is same as an end time of the locking duration. ### Claim 9 (depends on 7) The imaging method of claim 7, wherein a start time of the second exposure duration is same as a start time of the locking duration, and an end time of the second exposure duration is earlier than an end time of the locking duration. ### Claim 10 (depends on 7) The imaging method of claim 7, wherein a start time of the second exposure duration is later than a start time of the locking duration, and an end time of the second exposure duration is same as an end time of the locking duration. ### Claim 11 (depends on 7) The imaging method of claim 7, wherein a start time of the second exposure duration is later than a start time of the locking duration, and an end time of the second exposure duration is earlier than an end time of the locking duration. ### Claim 12 (depends on 1) The imaging method of claim 1, further comprising: controlling the gimbal to exit the stabilization mode after the second exposure duration elapses. ### Claim 13 (depends on 1) The imaging method of claim 1, further comprising: determining whether an imaging trigger event of the imaging device occurs; detecting the amount of incident light in response to the imaging trigger event; and comparing the amount of incident light with the preset value. ### Claim 14 (depends on 13) The imaging method of claim 13, further comprising: controlling the imaging device to perform imaging with the first exposure duration in response to the amount of incident light being greater than the preset value. ### Claim 15 An imaging system comprising: a gimbal configured to enter a stabilization mode in response to an amount of incident light being less than a preset value; and an imaging device mounted at the gimbal and configured to: perform imaging at a first exposure duration in response to the amount of incident light being greater than the preset value; and perform imaging at a second exposure duration longer than the first exposure duration in response to the amount of the incident light being less than the preset value and the gimbal entering the stabilization mode. ### Claim 16 (depends on 15) The imaging system of claim 15, wherein: the gimbal includes a yaw shaft frame, a roll shaft frame, and a pitch shaft frame; and the gimbal is further configured to control the yaw shaft frame, the roll shaft frame, and the pitch shaft frame for stabilization. ### Claim 17 (depends on 15) The imaging system of claim 15, wherein the second exposure duration is manually set or adjusted by a user. ### Claim 18 (depends on 15) The imaging system of claim 15, wherein the imaging device is further configured to detect the amount of incident light and determine the second exposure duration according to the amount of incident light. ### Claim 19 (depends on 15) The imaging system of claim 15, wherein the imaging device is further configured to: perform imaging at a first sensitivity in response to the amount of incident light being greater than the preset value;
