Latest Patents

Ding is credited with 1 patent: “Head-Mounted Device with Flicker Judder Mitigation.” The invention describes operating an electronic device, such as a head-mounted device, to reduce judder, double images, ghosting, and other display artifacts. It uses cameras to capture a scene and displays to present the images, while a flicker sensor measures light in the scene. The device determines the light’s frequency and phase, then uses that information to adjust or lock the cameras’ frame rate and exposure timing. It can also assess whether judder is present by calculating a display-artifact severity parameter and comparing it with a threshold.

Career Highlights

Ding’s listed patent reflects work on coordinating camera capture with flickering light to improve visual stability in head-mounted displays. The patent identifies Apple Inc. as the associated company.
