Field of view optimization

A method of displaying image content, wherein the method is performed by a head-up display comprising an eye-box having a first dimension and a second dimension, wherein the head-up display is arranged to form first image content in a first image area at a first image area distance from the eye-box and second image content in a second image area at a second image area distance from the eye-box, wherein the first image area distance is less than the second image area distance and the first image area is at least partially overlapping in the first dimension with the second image area, wherein the second image area extends less far in angular space than the first image area in both directions of the first dimension such that a size of the second image area in angular space is no more than that of the first image area, wherein the head-up display further comprises a user-tracking system, wherein the head-up display is arranged to determine a display pattern in real-time at least partially based on an eye- box position within the eye-box determined by the user-tracking system, and wherein the method comprises:

• changing at least one of the first and second image area distance based on a change to the eye-box position determined by the user-tracking system.
