The invention discloses a shaping signal control method for a voice coil actuator of a camera. The method comprises the following steps that rise/fall time of each rise/fall step in a shaping signal is calculated; the initial rise/fall amplitude of the corresponding rise/fall step is calculated according to the rise/fall time of each rise/fall step; a rise/fall amplitude fine tuning coefficient of the shaping signal is calculated according to the initial rise/fall amplitude of each rise/fall step; and a given value of the rise/fall amplitude of each rise/fall step is calculated according to both the rise/fall amplitude fine tuning coefficient of the shaping signal and the initial rise/fall amplitude of each rise/fall step. According to the invention, the frequency and damping coefficient in oscillation characteristic of a motor are taken into full consideration, oscillation of the motor is inhibited, and error between a clock period and a natural oscillation period of the voice coil motor is highly tolerant.
