Solution Overview
Problem
Existing image editing technologies lack the ability to separately apply light source and color effects to the foreground and background of an image, limiting the diversity and customization of selfie images.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single light source effect is applied to the entire image including foreground and background, then the processing is simple and fast, but the image effect diversity and customization are limited
Solution Approach 1:
The patent segments the image into foreground and background regions, allowing different light source effects to be applied to each region independently. This segmentation enables diverse and customized image effects while maintaining manageable processing complexity through region-based processing.
Solution Approach 2:
The patent applies different light source effects to different regions (foreground vs. background) of the image. By making the image processing non-uniform and region-specific, it achieves diverse and customized effects without requiring complete reprocessing of the entire image with multiple effects.
2Adaptability or versatility
If different light source effects are applied to foreground and background separately, then image effect diversity is improved, but processing time and computational resources increase
Solution Approach 1:
By segmenting the image into foreground and background regions once, the patent enables efficient separate processing of different light source effects. The segmentation is performed a single time, and then each region can be processed with its designated effect, reducing redundant computations.
Solution Approach 2:
The patent applies light source effects selectively to specific regions (foreground and background) rather than uniformly to the entire image. This partial action approach achieves customized effects while minimizing the computational scope for each effect application.
3Adaptability or versatility
If multiple effects are applied to the entire image, then effect diversity is achieved, but the ability to optimize effects for specific regions is lost
Solution Approach 1:
The patent divides the image into foreground and background regions, enabling independent optimization of light source effects for each region. This segmentation simplifies the complexity by providing clear boundaries for where each effect should be applied, rather than requiring complex masking and blending operations.
Solution Approach 2:
By applying different light source effects to different regions, the patent optimizes the visual appearance of each region specifically. The foreground can have one type of lighting effect while the background has another, creating a more natural and optimized image without requiring complex global adjustments.
Data Source
AI summary
At least one processor included in an electronic device may execute a camera, detect at least one object based on image data obtained through the camera in a first light source environment, analyze color properties of the detected at least one object, determine a first effect based on the analyzed color properties of the object, apply a second light source effect to the at least one object, the second light source effect being different from the first light source, and apply the first effect to a background except the at least one object. Various other embodiments identified through the specification are possible.
