The paper introduces the improvement on traditional Millikan＇s oil-drop instrument. By using image acquisition card, oil-drop image is captured for computer processing. Via computer programming, this card can catch experiment images dynamically and measure experimental data automatically. With improved mapping method, oil-drop charging amount is 1.598x10^-19C and error is reduced from the original 1.87% to 0.87%. The accuracy of the experiment is enhanced greatly and the experiment is characterized by repeatability, simple operation and easy measurement.
