  • CONTROL SYSTEM OF PHOTOGRAPHING DEVICE, METHOD AND DEVICE
    Publication number: 20240045172
    Abstract: Photographing device control system, method and device are provided. The photographing device includes a manual lens. The control system includes a parameter adjustment ring(s), a motor(s) and a processor(s). The parameter adjustment ring is arranged on the manual lens, and may be rotated to adjust a lens parameter(s) of the manual lens. A motor(s) is used to drive the parameter adjustment ring to rotate; the motor rotates to different angles based on a first user instruction. The processor is used to obtain the lens parameter of the manual lens when the motor is at each angle, and calibrate a conversion relationship(s) between the rotation angle of the motor and the lens parameters of the manual lens based on each angle and corresponding lens parameter thereof. A target rotation angle of the motor is determined based on the conversion relationship and a target lens parameter(s).
