Adaptive Enhance Slope Control (AESC): AESC is an optimal solution for step-type ringing control. Actually step-type ringing control has many kinds of designing to speed up actuation time of lens, but only one optimal solution can achieve strongly robustness with tolerance of VCM.
• Perfect design: No VCM tolerance. • Practical design: with VCM tolerance.
