Dynamic Analysis Area Selection for Video Lighting Synchronization

Solution Overview

Problem

Current systems for determining light effects in video content, such as Philips Hue Sync, use fixed predefined analysis areas, leading to light effects that often do not match the dynamic nature of video games, resulting in a mismatch between the video content and light effects.

Innovation Solution

A system and method that dynamically determine image characteristics from video frames by assessing the dynamicity of analysis areas within the frames, allowing for the selection of analysis areas with similar dynamicity levels to the overall video content, thereby aligning light effects with the video content's dynamics, using processors to compare and adjust light effects in real-time.

1Ease of operation

If fixed predefined analysis areas are used for color extraction, then the system complexity is reduced and ease of operation is improved, but the matching accuracy between light effects and video content deteriorates

Engineering Contradiction:

Improveease of operationVSAvoidmatching accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent implements dynamic analysis area selection by comparing the dynamicity level of candidate analysis areas with the overall video content dynamicity level. The system automatically adjusts which analysis areas are used for color extraction based on real-time dynamicity comparisons, allowing the analysis areas to adapt dynamically to different video content characteristics rather than using fixed predefined areas throughout.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the parameter of analysis area selection by introducing dynamicity level comparison. Instead of using fixed analysis areas, the system evaluates multiple candidate analysis areas and selects those whose dynamicity levels match the overall video content dynamicity level, thereby adapting the analysis parameters to the specific video content being processed.

AI summary

A system (1) is configured to determine a first level of dynamicity in video frames, determine a second level of dynamicity in each of a plurality of analysis areas (52,73) in the video frames, compare each of the second dynamicity levels with the first dynamicity level, select a subset (73) of the analysis areas based on the comparisons, determine image characteristics from the subset of analysis areas in the video content, determine one or more light effects based on the image characteristics, and control one or more lighting device to render the one or more light effects and/or store a light script specifying the one or more light effects. The light effects are to be rendered while the video content is rendered on a display device (9).
