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.
Claims20
A method comprising:
- identifying a color sequence of a light source component of a digital light processing (DLP) projector;
- tracking a motion of the DLP projector;
- predicting a color break up artifact produced by the DLP projector based on the color sequence and the motion of the DLP projector;
- generating a counter artifact that offsets the color break up artifact based on the predicted color break up artifact;
- and
- causing the DLP projector to display the counter artifact.
A computing apparatus comprising:
- a processor;
- and
- a memory storing instructions that, when executed by the processor, configure the computing apparatus to perform operations comprising:
- identifying a color sequence of a light source component of a digital light processing (DLP) projector;
- tracking a motion of the DLP projector;
- predicting a color break up artifact produced by the DLP projector based on the color sequence and the motion of the DLP projector;
- generating a counter artifact that offsets the color break up artifact based on the predicted color break up artifact;
- and
- causing the DLP projector to display the counter artifact.
A non-transitory computer-readable storage medium, the computer-readable storage medium including instructions that when executed by a computer, cause the computer to perform operations comprising:
- identifying a color sequence of a light source component of a digital light processing (DLP) projector;
- tracking a motion of the DLP projector;
- predicting a color break up artifact produced by the DLP projector based on the color sequence and the motion of the DLP projector;
- generating a counter artifact that offsets the color break up artifact based on the predicted color break up artifact;
- and
- causing the DLP projector to display the counter artifact.
