A display apparatus configured to display three-dimensional video viewable by a viewer wearing stereoscopic-viewing glasses. The display apparatus includes: an input module; a display device; an image input module; a detection module; and a recording module. The input module receives video data. The display device displays the three-dimensional video based on the received video data. The image input module receives a captured image from an image-capturing device that captures an image of an area around the display apparatus and on a side facing the display device. The detection module detects an image of the stereoscopic-viewing glasses from the received captured image. The recording module records the received video data when the image of the stereoscopic-viewing glasses is not detected by the detection module.
