AF Testing System
The AF testing system is designed to test the AF time and AF accuracy (repeatability) of cameras equipped with Auto Focus (AF) functionality. The system supports both automatic and manual testing options.

• LED Exposure Time and Frame Rate Tester for precise timing measurement;
• Near-Field Card Quick Switching Mechanism (test cards available in checkerboard or leaf patterns), includes two optical sensors to detect switching time, with switching speed ranging from 50ms to 100ms;
• Includes Automated Control Software, which controls the smartphone’s camera, near-field card switching mechanism, and exposure time tester to ensure synchronized operation;
• Includes Image Analysis Software, which analyzes the images or videos captured by the smartphone to determine the AF focus time. The imatest software can also be used to evaluate the accuracy of zoom clarity.

• Optional Finger-Touch Simulation Control Module for simulating user touch interaction;

◎ Optional Video Analysis Module, which analyzes single-frame exposure time, frame rate, frame drop, stuttering, and audio-video synchronization;

◎ Optional Interference Card Motion Device, used to test the impact of peripheral object movement on central focus accuracy.

The system includes the following important components:
• Near-focus and far-focus test cards
• LED timer
• Image analysis software (for near/far focus card clarity)

• Near-focus card switching system (including LED timer start-up system)
