Display Electronics With Content-Aware Dimming for Video Conferencing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display electronics and panels consume significant power during audio/video conferencing, adversely affecting battery life, and existing dimming methods are limited in power savings and do not proactively dim pixels based on content relevance.
Innovation Solution
Embodiments leverage features like background blurring and background replacement filters to dim pixels not actively displaying meaningful content, reducing power consumption by up to 50% in emissive displays without visual quality degradation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If display electronics operate at full brightness during audio/video conferencing, then visual quality is maintained, but power consumption increases significantly
Solution Approach 1:
The patent applies different brightness levels to different regions of the display based on content meaningfulness. The display is divided into meaningful regions (showing relevant video content) and non-meaningful regions (showing irrelevant background or static areas). Only meaningful regions maintain full brightness, while non-meaningful regions are dimmed, thereby reducing overall power consumption while preserving visual quality where it matters most.
2Loss of energy
If existing dimming methods are applied, then some power savings are achieved, but power reduction is limited and does not reach 50% reduction
Solution Approach 1:
The system continuously analyzes video content to determine which regions are meaningful and which are non-meaningful. This real-time feedback mechanism allows the display to dynamically adjust brightness levels based on the actual content being shown. By using machine learning models to classify regions and providing continuous feedback to the display control system, the patent achieves adaptive dimming that can reduce power consumption by up to 50%, significantly outperforming existing static dimming methods.
3Duration of action of stationary object
If pixels are dimmed to reduce power consumption, then battery life is extended, but visual quality may be compromised
Solution Approach 1:
The patent preserves full brightness and visual quality in meaningful regions where important video content is displayed, while applying dimming only to non-meaningful regions. This selective approach ensures that users continue to see clear, high-quality images of relevant content (such as speakers in video conferences) while reducing power consumption through dimming of irrelevant areas, thus extending battery life without compromising overall visual quality.

AI summary
Systems and methods for management of display electronics during audio/video conferencing. The systems first delineate a person or user from the background in a video frame, with a bounding box. The systems apply a dimming factor to pixels associated with the background in a video frame. The dimming factor can be a percent of the original intensity of the pixel. The dimming factor is a variable; in a first order, the dimming factor varies as a function of distance from the bounding box. In a second order, the dimming factor has a rate of change that varies as it is applied across the background. The dimming factor is smaller adjacent to the person and larger at the periphery of the video frame.
