An HMD includes: a camera configured to image an external landscape; a camera abnormality detector configured to detect operation abnormality of the camera; a sensor group configured to detect a position, a distance, and the like of an object within the external landscape; a sensor abnormality detector configured to detect operation abnormality of the sensor group; an image generator configured to generate an image; and a mode switcher configured to switch a processing mode of the image generator. The image generator has an AR advanced processing mode of generating a high-accuracy AR advanced image by using image data captured by the camera and detection data detected by the sensor group, and an AR simple processing mode of generating AR simple image simpler than the AR advanced image. When an operation of the camera or the sensor group is abnormal, the mode switcher switches into the AR simple processing mode.
