Abstract
An augmented reality system is disclosed that includes an image source configured to generate an image, and a display element configured to display the image. The system further includes an optical relay configured to project the image onto the display element. The system further includes a light sensor configured to quantify an amount of ambient light passing through, the display element. The system further includes a tracker processing unit operatively coupled to the light sensor, the image source, and the optical relay. The tracker processing unit includes a processor, and a memory configured to store instructions executable by the processors. The processors are instructed to receive sensor data from the light sensor, receive the image from the image source, update a pixel characteristic for one or more pixels of the image based on the sensor data, and transmit an updated image to the optical relay.
