Abstract
A display apparatus including gaze-tracking means, image renderers, liquid-crystal devices including liquid-crystal structure and control circuit, to shift light emanating from given pixel of image renderer to multiple positions, given pixel including colour component; and processor configured to: process gaze-tracking data to determine gaze direction of user's eye; determine gaze point; display first output image frame; detect if magnitude of difference between first output value and initial second output value of colour component of given pixel in first and second output image frames exceeds first threshold difference; when detected that magnitude of difference exceeds first threshold difference, update initial second output value to sum of first output value and product of distance factor and difference between initial second output and first output values; and display second output image frame.
