Abstract
A method of operating an electronic device such as a head-mounted device to mitigate judder, double images, ghosting, and other display artifacts is provided. The method can include acquiring images of a scene with one or more cameras, outputting the acquired images of the scene with one or more displays, sensing light in the scene with a flicker sensor, obtaining a frequency and a phase of the sensed light, and setting or locking a frame rate of the cameras based on the frequency of the sensed light. The method can also include shifting or locking exposure periods of the cameras based on the phase of the sensed light. Determination of whether judder is present can involve computing a display artifact severity parameter and comparing that parameter to a threshold.
