Dynamic Front Image Positioning in Dual Camera Synthesis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dual shot modes in portable terminals fix the front image to a specific position on the rear image regardless of the rear image content, limiting the composition and integrity of the combined images.
Innovation Solution
A system and method that allows the front camera image to be positioned and transformed within a desired area of the rear camera image using scaling, rotation, and translation operations, and combined using image warping, texture mapping, or other processing techniques to create a synthesized image, with user input for selecting the region of interest and adapting to changes in the rear image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the front image is fixed to a specific predetermined position on the rear image, then the dual shot mode can be implemented simply, but the composition and integrity of the combined images are limited
Solution Approach 1:
The patent applies dynamics by making the front image position adjustable rather than fixed. The system allows users to dynamically reposition the front image within the rear image based on different composition requirements, transforming a static fixed-position system into a dynamic adjustable-position system that adapts to various imaging scenarios.
Solution Approach 2:
The patent changes the position parameter of the front image from a fixed predetermined location to variable positions within the rear image. By allowing the position parameters (x, y coordinates) to be changed based on user input or detected objects, the system achieves flexible composition while maintaining implementation simplicity.
2Device complexity
If the front image is fixed at a predetermined position, then the system complexity is low, but the integrity and natural synthesis of front and rear images is compromised
Solution Approach 1:
The patent implements self-service by enabling the system to automatically detect objects or regions of interest in the rear image and automatically determine appropriate positions for the front image. This automatic positioning based on detected content maintains image integrity without requiring complex manual adjustment mechanisms.
Solution Approach 2:
The system incorporates feedback mechanisms where the position and content of the front image are adjusted based on feedback from image analysis. The system analyzes the rear image content and provides feedback to determine optimal positioning, ensuring natural synthesis while managing system complexity through automated feedback loops.
3Productivity
If the front image is automatically positioned without user input, then the operation speed is high, but the adaptability to different user requirements is reduced
Solution Approach 1:
The patent applies preliminary action by pre-processing the rear image to detect objects, regions of interest, or characteristic features before final positioning. This preliminary analysis enables the system to quickly determine appropriate positions while still allowing user input to override automatic positioning when specific adaptability is required.
Solution Approach 2:
The system achieves universality by implementing multiple positioning modes: automatic positioning based on detected content, manual positioning through user input, and hybrid approaches. This multi-functional positioning capability allows the system to adapt to different user requirements while maintaining high productivity through automated options.
Data Source
AI summary
A system generates a synthesized image by combining content of a first image with content of a second image where both the first and second images are acquired by a portable terminal, The system identifies a portion of the second image, selects at least a part of the portion of the second image as a region of interest and generates a synthesized image by incorporating content of the first image in the region of interest. The method displays and stores the synthesized image.
