Patent number: 12243496Abstract: Often when there is a glare on a display screen the user may be able to mitigate the glare by tilting or otherwise moving the screen or changing their viewing position. However, when driving a car there are limited options for overcoming glares on the dashboard, especially when you are driving for a long distance in the same direction. Embodiments are directed to eliminating such glare. Other embodiments are related to mixed reality (MR) and filling in occluded areas.Type: GrantFiled: May 24, 2023Date of Patent: March 4, 2025Assignee: Intel CorporationInventors: Arthur J.

Patent number: 10283078Abstract: Methods and apparatuses pertaining to adaptive display partial update may involve determining whether partial update for an image frame is allowed and, responsive to a determination that the partial update for the image frame is allowed, determining whether the partial update is applicable to the image frame. Responsive to a determination that the partial update is applicable to the image frame, whether or not at least a difference between one or more properties of the image frame and one or more properties of a previous image frame exceeds a threshold may be determined. A partial-frame processing may be performed to partially update the image frame responsive to a determination that the difference does not exceed the threshold.Type: GrantFiled: January 16, 2017Date of Patent: May 7, 2019Assignee: MediaTek Inc.Inventors: Wen-Fu Lee, Te-Hao Chang, Ying-Jui Chen
