Abstract
Techniques for correcting a vertical angular image misalignment in stereoscopic images generated by an extended reality (ER) system are disclosed. A hologram is identified. This hologram is displayed in a scene of the ER system. A spatial frequency of the hologram is determined. A determination is made that the spatial frequency exceeds a spatial frequency threshold. The spatial frequency of the hologram is reduced until the spatial frequency is below the spatial frequency threshold. Such an operation results in a compensation being performed for a vertical angular image misalignment that exists between the stereoscopic images.
