LED Background Image Control for Performer Outline Glow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In virtual production shooting using LED displays, the self-luminous nature of the LED display causes the performer's outline to appear as if it is emitting light, leading to unintended lighting effects in captured images.
Innovation Solution
A method is employed to reduce the light intensity of the region where the performer overlaps on the LED display's image, using a computer system to determine and adjust the light intensity reduction region based on the performer's position and camera angle, generating a display image with reduced light intensity in the overlapping area.

Engineering Contradiction Analysis
1Illumination intensity
If the LED display is used as a self-luminous background device, then the background image can be displayed with high brightness and clarity, but the performer's outline appears to be emitting light causing unintended lighting effects
Solution Approach 1:
The patent applies local quality by differentiating the light intensity characteristics of different regions on the LED display. Specifically, the region corresponding to the performer's position (second region) is controlled to have lower light intensity compared to other background regions, while maintaining high brightness in non-performer areas. This localized adjustment eliminates the harmful outline effect without compromising overall background image quality.
Solution Approach 2:
The patent segments the LED display surface into multiple regions based on the performer's position: a first region (non-performer area), a second region (performer overlap area), and potentially a third region (other areas). By independently controlling the light intensity of each segment, the system can reduce light emission in the performer's outline area while maintaining brightness elsewhere, thus resolving the contradiction between overall brightness and localized harmful effects.
2Illumination intensity
If the LED display emits light from behind the performer, then the background is well-illuminated, but the performer's outline appears to be emitting light in captured images
Solution Approach 1:
The patent implements local quality control by adjusting the light intensity of specific LED display regions corresponding to the performer's position. The second region (performer overlap area) is set with reduced light intensity to prevent outline emission effects, while other regions maintain normal illumination. This localized adjustment ensures reliable image capture without the harmful artifact of glowing outlines.
Solution Approach 2:
The patent segments the display area into multiple zones including a first region, a second region (performer position), and a third region. By independently controlling light emission in the second region, the system eliminates the unreliable outline effect in captured images while preserving background illumination quality, thus improving overall image capture reliability.

AI summary
Provided is an information processing method that includes displaying, on a display that displays an image serving as a background of an object, a display image in which light intensity of a region where the object overlaps is reduced on an image captured by a camera that shoots at least a part of an area of a display surface of the display.
