VCM VCM A closed-loop method for restricting VCM moving area VCM driving device for the same lens module for user device for the same and user device for the same
By varying the linear position of the lens with respect to the variation of the VCM driving current in the barrel to correspond to the entire output range of the ADC, the moving distance per code output from the ADC can be kept constant and the accuracy of the lens position control can be improved.
