Abstract
A display apparatus and an operation method thereof are provided. The display apparatus includes a 3D display module, a camera, and a processing circuit coupled to the 3D display module and the camera. The camera is configured to shoot a viewing field of the 3D display module to generate a photo. The processing circuit is configured to output an image stream to the 3D display module to display a screen, and recognize the photo to obtain a face direction and a sight direction of a person in the viewing field. The processing circuit determines whether to enable a vestibulo-ocular reflex (VOR) compensation mode for the image stream according to the face direction and the sight direction.
