Abstract
In a display apparatus, a liquid-crystal structure, arranged in front of an image renderer, is controlled to shift light of a given sub-pixel to target positions according to a shifting sequence in a repeated manner, while output image frames are displayed. To generate a given output image frame, a given target position to which the light is to be shifted is determined based on the shifting sequence. An input colour value of the given sub-pixel provided in a given input image frame is then adjusted to generate an output colour value of the given sub-pixel for the given output image frame, based on an output colour value of at least one other sub-pixel whose light overlaps with the given target position during display of a previous output image frame, and a retention coefficient between a colour of the at least one other sub-pixel and a colour of the given sub-pixel.
