1. An apparatus for generating a high-rate video for displaying to a user on a display device, the apparatus comprising:
a camera for capturing a video at a first frame rate;
a motion sensor for capturing movement of a display device;
a motion tracker for estimating motion of the camera based on images of the video captured at the first frame rate and the motion reported by the motion sensor;
an image generator for generating the high-rate video at a second frame rate by up-sampling the video captured at the first frame rate, wherein images of the high-rate video are output emulating a video captured at the second frame rate, and wherein the up-sampling comprises: extrapolating images of the video captured at the first frame rate using geometrical warping thereby causing content of the high-rate video to be displayed counteracting the movement of the display device; and
a display for displaying the high-rate video to the user.
