Image Shadow Removal for Camera Accessories
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When using camera accessories like selfie sticks, the shadows they cast often appear in photographs, making the images look abrupt and unrealistic, and detract from their aesthetic quality.
Innovation Solution
An image processing method and apparatus that identifies and eliminates the shadow areas of camera devices and their support accessories in images, using feature recognition and processing techniques to enhance the image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If camera accessories like selfie sticks are used to support the photographing device, then the photographing device can be positioned at various angles and distances, but the accessories and their shadows appear in the photographed image, making it look abrupt and unrealistic
Solution Approach 1:
The patent extracts and removes the harmful shadow elements from the photographed image while preserving the useful photographing effect. The image processing system identifies shadow regions caused by photographing devices and accessories, then selectively removes these shadows through pixel manipulation and image synthesis techniques, achieving separation of the harmful shadow component from the useful image content
Solution Approach 2:
The patent converts the harmful shadow appearance into a benefit by using the shadow information to guide image processing. The system utilizes shadow detection and segmentation to identify affected regions, then applies targeted processing such as inpainting and pixel blending to restore the underlying scene appearance, transforming the shadow problem into an opportunity for enhancing image quality
2Object-affected harmful factors
If the shadow area of the target object is eliminated from the original image, then the aesthetics of the image is improved and the image does not appear obtrusive, but additional image processing steps are required
Solution Approach 1:
The patent segments the image processing task into distinct functional modules: shadow detection, shadow region segmentation, shadow elimination, and image synthesis. This modular segmentation allows each processing step to be optimized independently while maintaining overall system efficiency, reducing the complexity burden despite the multiple processing steps required
Solution Approach 2:
The image processing system performs self-service by automatically detecting and processing shadows without requiring manual intervention. The system autonomously identifies shadow regions, determines appropriate processing parameters, and executes the elimination process, reducing the operational complexity for users while maintaining sophisticated processing capabilities

AI summary
An image processing method includes obtaining an original image, and identifying a shadow area of a target object in the original image. The target object includes at least one of a photographing device or a support apparatus of the photographing device. The method further includes eliminating the shadow area of the target object in the original image.
