Travel curve test method and system of camera-shooting mode motor and mobile terminal

The invention discloses a travel curve test method and system of a camera-shooting mode motor, and a camera-shooting mode is assembled on a mobile terminal. The method comprises the following steps of utilizing a jig fixing mobile terminal, adjusting the position of a test chart, quantitatively controlling a drive current of a VCM motor to be tested through a motor driving module of the camera-shooting mode, recording coded value of a register corresponding to the drive current, collecting contrast value of the targeting positions of test chart images of different drive currents through an image signal processor of the camera-shooting mode, recording, and drawing the coded value of the register and relation curve of the contrast value. By the adoption of the travel curve test method, extra test devices are not needed, on the basis of original hardware configuration of the mobile terminal, the curve is formed by the drive current of the camera-shooting mode and the contrast value of collecting the images to simulate the travel curve of the VCM motor, the problem that the moving distance of the camera-shooting mode is hard to be measured is solved, simulation accuracy is high, and the problems of the focusing failure of the camera-shooting mode and the like can be analyzed precisely.
