In a remote smart collaboration application, sharing seamless and consistent information between a local site and interacting remote participants is essential. Often visual seams are created when inconsistent visual information is shared due to heterogeneous projector-camera systems (ProCams). One known issue is flickering noise occurred from re-capturing projected scenes with the camera of ProCams. In this paper, we design and implement an automatic and instant flicker-free calibration. With the proposed method, ProCams can remove or mitigate flicker problems by controlling both camera and projectors of ProCams to detect and resolve flickers. To illustrate our method, we present an exemplar ProCams configuration, flicker detection options and automatic flicker resolution strategy.
