Abstract
Disclosed is a display apparatus with gaze-tracking means, light source(s), eyepiece lens, and processor(s) configured to: process gaze-tracking data to determine a gaze direction; determine relative position of a pupil with respect to eyepiece lens and relative orientation (A) of the pupil with respect to optical axis (OO') of eyepiece lens; estimate distortions per pixel(s) in image, based on the relative position, the relative orientation and distortion information; identify an image segment whose pixels' estimated distortions are higher than predefined threshold distortion; modify image by replacing pixels of identified image segment with black pixels or near-black pixels; and utilise modified image for display to given eye via light source(s).
