Dual Camera Mobile Terminal Natural Selfie Synthesis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminals have limitations in selecting and editing images taken with both front and rear cameras, making it inconvenient for users to capture and combine images of themselves and their subjects naturally.
Innovation Solution
A mobile terminal with a method to consecutively photograph and select desired images from multiple shots, allowing for natural synthesis and independent editing of images from both the photographer and the photographing target, using dual cameras and advanced image processing algorithms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the front camera is used to photograph the user, then the user can capture self-images, but the user cannot pose naturally because they are holding the terminal
Solution Approach 1:
The camera system is segmented into two separate cameras: a front camera for capturing the user and a rear camera for capturing the subject. This segmentation allows the user to hold the terminal steadily for subject photography while the front camera independently captures natural user images without requiring the user to look at the screen or adjust posing manually.
Solution Approach 2:
The patent merges the functionality of two cameras (front and rear) into a coordinated system where both cameras operate simultaneously to capture complementary images. The controller synchronizes the operation of both cameras to take photos at the same time, combining their functions to solve the posing problem.
2Manufacturing precision
If multiple images are taken consecutively, then the user can select the best image, but it is difficult to naturally combine the photographer and subject images
Solution Approach 1:
The system merges the images captured by the front camera (user) and rear camera (subject) into a single composite image. The controller coordinates both cameras to capture images simultaneously and combines them seamlessly, ensuring natural alignment and consistent timing between the photographer and subject images.
Solution Approach 2:
The system provides feedback to the user by displaying the captured images and allowing selection and editing. The user can review the combined images, select desired ones, and perform independent editing operations with the system providing real-time feedback on the editing results.
3Manufacturing precision
If the terminal is held for self-photography, then the user can capture images, but the image quality and stability are compromised
Solution Approach 1:
The photography function is segmented into two independent camera systems: the rear camera for high-quality subject photography that remains stable when held, and the front camera for user self-portraits that captures the user's face and expression without requiring screen viewing or manual posing adjustments.

AI summary
A mobile terminal including a first camera on a first surface of the mobile terminal; a second camera on a second surface of the mobile terminal; a display unit; and a controller configured to control the first camera to obtain a first image, control the second camera to obtain a plurality of second images, and display the first image and the plurality of second images on the display unit.
