Abstract
There is provided a method of operating a wearable heads-up display (WHUD). The WHUD may include a light source, a spatial modulator, and a display optic. The method may include generating, by the light source, an output light to form an image viewable by a user of the WHUD. The method may also include receiving a position of a pupil of the user relative to an eyebox of the WHUD, and obtaining an image correction map based on the position of the pupil. Moreover, the method may include adjusting the output light to form an adjusted output light. The adjusted output light may be adjusted based on the image correction map to reduce at least one of an intensity non-uniformity and a color balance non-uniformity of the image. The method may also include directing, by the display optic, the adjusted output light into a field of view of the user.
