Abstract
A data processing apparatus comprises receiving circuitry to receive tracking data indicative of at least one of a tracked position and orientation of a head-mountable display (HMD), image processing circuitry to generate a sequence of images frames for display in dependence upon the tracking data, detection circuitry to detect an image feature in a first image frame and to detect a corresponding image feature in a second image frame, and correlation circuitry to: calculate a difference between the image feature in the first image frame and the corresponding image feature in the second image frame; generate difference data indicative of a difference between a viewpoint for the first image frame and a viewpoint for the second image frame in dependence upon the difference between the image feature in the first image frame and the corresponding image feature in the second image frame; and generate output data in dependence upon a difference between the difference data and the tracking data associated with the first and second image frames.
