In and relating to displays

An apparatus for controlling a display device to generate a colour image for viewing by a user on a display, the colour image being formed by at least three colour components, each of the colour components including two or more different colours to be displayed with predetermined relative timings, the apparatus comprising:

• an image processor configured to
• receive image data defining an intended position of first, second, and third colour components of a feature to be sequentially displayed as an element in the colour image;
• receive rate data indicative of a rate of change in orientation of the display relative to a direction of gaze of an eye of the user;
• determine a displaced position on the display for displaying each of the first and third colour components of the feature by adjusting the intended position of the first and third colour components according to the respective colour, the received rate data, and the predetermined relative timings relative to a timing of the second colour component, the displaced position of the first and third colour components being different from the intended position of the second colour component, and
• output the displaced position of each of the first and third colour components to the display device for display of the first and third colour components at the respective displaced position, and outputting the intended position of the second colour component to the display device for display of the second colour component at the intended position.

A computer program product comprising one or more non-transitory computer-readable mediums having stored thereon computer program code which when executed by one or more processor causes a process to be carried out for controlling a display device to generate a colour image for viewing by a user on a display, the colour image being formed by at least three colour components, each of the colour components selected from two or more different colours to be displayed with predetermined relative timings, the process comprising:

• receiving image data defining an intended position of first, second, and third colour components of a feature to be sequentially displayed as an element in the colour image;
• receiving rate data indicative of a rate of change in orientation of the display relative to a direction of gaze of an eye of the user;
• determining a displaced position on the display for displaying each of the first and third colour components of the feature by adjusting the intended position of the first and third colour components according to the respective colour, the received rate data and the predetermined relative timings relative to a timing of the second colour component, the displaced position of the first and third colour components being different from the intended position of the second colour component;
• and
• outputting the displaced position of each of the first and third colour components to the display device for display of the first and third colour components at the respective displaced position, and outputting the intended position of the second colour component to the display device for display of the second colour component at the intended position.
