HIGH-FIDELITY IMAGE STABILITY WITH NEAR-EYE DISPLAYS - DYNAMICALLY CHANGING DUTY CYCLE TO REDUCE JUDDER EFFECT

摘要

Methods and systems relating to compensation for discrepancies in an image that may be captured with a moving camera or a moving head. The visual artifacts in the visual field may be reduced or eliminated by monitoring head and camera movements for a Heads Up Display (HUD) application, and feeding back the movement data to a compensation circuit to eliminate or reduce the visual artifacts such as judder effect, as the head and the camera move relative to the objects that the camera may be capturing. The duty cycle of one or more pixels and/or one or more groups of pixels of the display may be varied at different rates for different head and camera movement speeds. The faster the camera or head moves the shorter the duty cycle that may be applied to the display so that the image has low persistence.
