Head-Mounted Display Lens Distortion Correction

The patent applies preliminary action by pre-calculating and applying reverse distortion correction to the images before they are displayed. The correction amount is determined based on the strong distortion characteristics of the lenses, and the corrected images are stored in advance. This ensures that when the images pass through the distorted lenses, the distortion effects are canceled out, achieving accurate depth perception without requiring perfect manual alignment of the lenses.

The patent implements feedback by measuring the actual position of each lens relative to its corresponding display, determining the specific distortion characteristics for each lens, and then adjusting the correction amount for each lens's image accordingly. This individualized correction approach compensates for mounting position errors, allowing simple manual assembly while achieving precise optical alignment through software-based distortion correction.

The patent reduces device complexity by performing distortion correction in advance during the image preparation stage. The correction amounts are calculated based on measured lens positions and distortion characteristics, and the corrected images are stored for direct display. This eliminates the need for real-time complex calculations during operation, simplifying the overall system while maintaining high optical alignment accuracy.
