Abstract

A method for calibrating a display system is provided. A test pattern for display is presented. The test pattern includes a plurality of blobs. Using a camera, an image comprising one or more of the plurality of blobs in the presented test pattern is captured. An exposure calibration parameter is calculated using a ratio of a maximum brightness level capable of being read by the camera to a maximum brightness level determined from the captured one or more blobs in the test pattern. The exposure of the camera of the display system is calibrated using the exposure calibration parameter. A display system configured to implement the method is also provided.
