ARTIFACT CANCELLATION IN CAPTURE IMAGES OF LED TILE DISPLAY

Systems and methods for capturing moving images from a video display controlled using pulse width modulation (PWM) are disclosed. In particular, systems and methods are disclosed for synchronizing display timing with camera timing in order to reduce or eliminate artifacts occurring in captured moving images due to asynchronous interaction between camera shutter/exposure timing and timing of display PWM control signals. 披露了用于从使用脉宽调制(PWM)控制的视频显示器捕获移动图像的系统和方法。特别地，披露了用于使显示器时序与相机时序同步以便减少或消除因相机快门/曝光时序与显示器PWM控制信号的时序之间的非同步交互而出现在所捕获移动图像中的伪影的系统和方法。
