SYSTEM AND METHOD OF COMPENSATING FOR REAL WORLD ILLUMINATION CHANGES IN AUGMENTED REALITY

摘要

A method in some embodiments is performed using an augmented reality head-mounted display (HMD) that includes a primary display and a dimmable filter that is external to the primary display. An illuminance sensor measures the illuminance of a real-world scene. Based on the illuminance, a target brightness of a virtual object and a target dimming level of the dimmable filter are selected. The virtual object is displayed on the primary display with the target brightness, and the dimmable filter is adjusted to the target dimming level. Changes to virtual object brightness and dimming level of the filter may be performed gradually to avoid sudden brightness changes that may be distracting to a user. In some embodiments, the luminance sensor is used to measure a white point of the real-world scene, and the virtual object is color balanced based on the measured white point.
