Multi-Preview Camera Capture Without Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with multiple cameras require users to switch modes and make multiple selections to capture images from both front and rear cameras, which is inconvenient and not fully utilizing the dual-camera feature.
Innovation Solution
An electronic device method and apparatus that allows generating a photograph image by displaying preview images from multiple image sensors in multi-preview mode and enabling users to capture images directly from the second preview area upon detection of a predetermined user input, without needing to switch to single-preview mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electronic device operates in multi-preview mode to display preview images from both front and rear cameras, then the device can show both cameras simultaneously, but the user cannot capture images directly without switching to single-preview mode
Solution Approach 1:
The system prepares multiple preview images from different cameras in advance and displays them simultaneously in multi-preview mode. The user can directly capture images from either preview without needing to switch modes, as the capture functionality is pre-configured to work with both previews.
Solution Approach 2:
The electronic device integrates multiple camera functions into a single operational mode. The multi-preview mode serves dual purposes: displaying previews from both cameras and enabling direct image capture from either camera, eliminating the need for separate single-preview modes.
2Ease of operation
If the electronic device requires switching to single-preview mode to capture images, then the image capture process is simplified, but the dual-camera feature is not fully utilized
Solution Approach 1:
The system merges the functionality of multiple cameras and the image capture operation into a single integrated mode. Users can capture images from either the front or rear camera while remaining in multi-preview mode, combining what were previously separate functions into one unified操作流程.
3Adaptability or versatility
If the electronic device displays preview images in Picture-In-Picture form, then both cameras can be visualized simultaneously, but the user interface becomes more complex
Solution Approach 1:
The system uses Picture-In-Picture display to present multiple preview images in a spatial arrangement that fits within the screen dimensions. By utilizing the spatial dimension effectively, the interface displays both camera previews simultaneously without requiring additional screens or complex navigation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient image capture from either front or rear cameras in multi-preview mode, enhancing user experience by simplifying the process and fully utilizing dual-camera functionality.
Implementation Method 1
The electronic device has image sensors on the front and back to convert received light to a digital signal
Data Source
AI summary
A method for generating a photograph image by using any of the preview images captured by multiple image sensors on the electronic device and displayed in a multi-preview mode on the device is provided. The method includes displaying a first preview image obtained from a first image sensor in a first preview area; displaying a second preview image obtained from a second image sensor in a second preview area; and upon detection of a predetermined first user input in the second preview area, generating a photograph image by using the second preview image.
