Abstract: A system is disclosed for correcting a world-additive display of a head mounted device (HMD). The system includes a processor of a controller of the HMD connected to the world-additive display and a memory on which are stored machine-readable instructions that when executed by the processor, cause the processor to perform a process. The process includes receiving optical data from the world-additive display, receiving background data from an optical sensor connected to the controller, deriving scene estimate data from the background data, extracting display color estimate data from the optical data, generating a correction map based on the scene estimate data and the display color estimate data, and applying the correction map to the optical data. Corresponding methods and devices are also disclosed.
