Problems solved by technology

[0003] However, when the lens is falling back, the impact between the lens and the gasket in the base will produce a crashing sound, and the farther the lens is pushed out, the louder the impacting sound when falling back
This not only affects the user experience, but also may damage the lens when the gasket is damaged or the cushioning force is weakened, affecting the reliability and life of the lens

Abstract

The invention provides a motor control method and device and a shooting device. The method comprises that a motor power-off instruction is received; whether present power supply current of a motor is greater than a preset value is determined; if yes, the present power supply current of the motor is reduced to the preset value; and the present power supply current of the motor is reduced from the preset value to zero gradually according to preset step length and time interval. According to the motor control method and device and shooting device of the invention, a lens can be recovered to a pedestal of the shooting device gradually, impact and noise between the lens and a pedestal pad of the shooting device are reduced, the lens safety is improved, and the service life of the lens is prolonged.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a motor control method, device and imaging equipment. Background technique [0002] Generally, cameras use motors to control the retraction of the lens. When the user uses the camera to take pictures, the motor is powered on to push the lens to the set position. When the shooting is finished, the motor is powered off, and the lens loses its driving force and falls back into the camera base. [0003] However, in the process of the lens falling back, the impact of the lens and the spacer in the base will produce a crashing sound, and the farther the lens is pushed out, the louder the crashing sound when falling back. This not only affects the user experience, but also may damage the lens when the gasket is damaged or the cushioning force is weakened, affecting the reliability and life of the lens. Contents of the invention [0004] This application aims t...
