Abstract: A method for configuring a digital light projector (DLP) of an augmented reality (AR) display device is described. A light source component of the DLP projector is configured to generate a single red-green-blue color sequence repetition per image frame. The AR display device identifies a color sequence of the light source component of the DLP projector and tracks a motion of the AR display device. The AR display device adjusts an operation of the DLP projector based on the single red-green-blue color sequence repetition, the color sequence of the light source component of the DLP projector, and the motion of the AR display device.

Abstract: Disclosed are systems and methods for adaptively adjusting brightness of a wearable device projection system. The systems and methods perform operations comprising: causing projection elements of the AR wearable device to project an image; receiving a measure of ambient light from an ambient light sensor; adjusting one or more hardware parameters of the projection elements of the AR wearable device based on the measure of ambient light; modifying one or more color values of the image displayed by the projection elements of the AR wearable device based on the measure of ambient light; and projecting the image with the modified color values using the projection elements of the AR wearable device with the adjusted one or more hardware parameters.
