Mobile Terminal Composite Image Synthesis via Dual Camera Preview
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for generating composite images on mobile terminals are complex, requiring users to manually select and synthesize images from an album, which is cumbersome.
Innovation Solution
A photographing method that allows users to divide a preview screen into sub-screens using sliding or bending inputs, enabling simultaneous capture and synthesis of images from front- and rear-facing cameras when identifiers overlap, simplifying the image synthesis process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually select and synthesize images from an album using image synthesis software, then composite images can be generated, but the operations become complicated and cumbersome
Solution Approach 1:
The system performs image synthesis directly during the photographing process rather than requiring post-processing. The front and rear cameras capture images simultaneously, and the controller automatically synthesizes them in real-time, eliminating the need for users to manually select and process images from an album later.
Solution Approach 2:
The patent combines the photographing function and image synthesis function into a single integrated process. By merging the simultaneous capture from front and rear cameras with automatic composite image generation, the system eliminates the separate steps of manual image selection and synthesis that were required in traditional workflows.
2Ease of operation
If the photographing preview screen is divided into sub-preview-screens for simultaneous camera control, then ease of operation improves, but screen space and display complexity increase
Solution Approach 1:
The photographing preview screen is divided into multiple sub-preview-screens, with each sub-screen displaying the real-time preview from a specific camera (front or rear). This segmentation allows users to visually control both cameras simultaneously and understand their respective viewing angles and captured content before synthesis.
Solution Approach 2:
The system utilizes the vertical dimension of the mobile terminal's screen to arrange sub-preview-screens in different directions (front camera preview and rear camera preview stacked vertically). This dimensional arrangement maximizes the use of available screen space while maintaining clear visual separation and control of both camera feeds.

AI summary
A photographing method and a mobile terminal are provided. The method includes: receiving a first input by a user when a current screen displays a photographing preview screen; in response to the first input, updating the photographing preview screen and displaying it as a first sub-preview-screen and a second sub-preview-screen; receiving a second input by the user; in response to the second input, controlling a first photographing identifier displayed on the first sub-preview-screen and a second photographing identifier displayed on the second sub-preview-screen to move; and when the first photographing identifier and the second photographing identifier overlap, controlling a front-facing camera and a rear-facing camera to capture a first image and a second image respectively, and displaying a composite image of the first image and the second image.
