In a video communication performed by using an imaging unit and a video display device, a communication terminal acquires a video captured by the imaging unit, stores at least a part of the acquired video in a storing unit, and determines a video of a predetermined interval after a start of the video communication being currently in progress from the stored video, as a replacement video. Then, the communication terminal is triggered when a predetermined start condition is satisfied during the output of the video captured by the imaging unit, and outputs the replacement video instead of the video.
