Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for capturing group photos often result in complexity and stiffness, as they require manual combination of images taken by different individuals, making it difficult to include everyone in the same frame without assistance.
Innovation Solution
An image processing method and apparatus that allows a client device with a camera and display to take and process photographs, applying transparency processing and alignment techniques to combine images of different subjects and backgrounds seamlessly, enabling the creation of a single group photo including all individuals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If manual combination of images is used to include photographer in group photo, then completeness of group photo is improved, but operation complexity increases
Solution Approach 1:
The system enables self-service photography by allowing the photographer to capture and composite group photos independently using the mobile device's camera and processing capabilities, eliminating the need for manual assistance while ensuring complete inclusion of all subjects
Solution Approach 2:
The patent replaces manual mechanical image combination operations with automated digital image processing systems that use algorithms to detect, align, and composite multiple photographs, significantly reducing operational complexity while maintaining completeness
2Device complexity
If simple combination of images is used to create group photo, then operation complexity is reduced, but photo quality deteriorates
Solution Approach 1:
The system substitutes simple mechanical image juxtaposition with sophisticated digital image processing that includes automated alignment, perspective correction, and seamless compositing algorithms, achieving high photo quality while keeping operations simple
Solution Approach 2:
The patent applies parameter changes in image processing such as adjusting transparency, blending modes, geometric transformations, and color matching to create natural-looking composites that maintain high quality without requiring complex manual operations
3Device complexity
If traditional camera methods are used to capture group photo, then equipment simplicity is maintained, but completeness of group photo deteriorates
Solution Approach 1:
The patent segments the group photo capture process into multiple individual photographs taken by the photographer, then uses digital processing to composite them into a single complete image that includes the photographer and all other subjects
Solution Approach 2:
The system transitions from capturing a single two-dimensional group photo to capturing multiple two-dimensional images that are then combined into a composite image, adding a temporal and computational dimension to achieve completeness

AI summary
A method for processing images is performed at a client device having a camera, including: capturing a first image using the camera and extracting a first subject and a first background from the first image; rendering the first background in the display; comparing the first background with a set of second backgrounds dynamically captured by the camera on the display; generating a visual or audible indicator upon determining that one of the set of second backgrounds matches the first background; in response to the visual or audible indicator, capturing a second image using the camera, the second image including a second subject; and generating a third image by combining the first image and the second image, the third image including the first subject, the second subject and the first background.
