Mobile Terminal Image Preview and Cropping Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminals cannot increase the view angle of a taken photo after it has been captured, limiting user convenience by preventing unseen regions from being viewed.
Innovation Solution
A mobile terminal with a camera, memory, and controller that allows for previewing a partial region of an image, taking photos, displaying and editing the entire image, and cropping regions to save the edited portion, thereby enabling users to restore unseen regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display unit shows only a partial region of the taken photo to fit the screen, then the display compatibility is improved, but the user cannot view the entire captured image including unseen regions
Solution Approach 1:
The controller displays the entire taken photo before allowing cropping operations, enabling users to preview all captured content including unseen regions before finalizing the crop. This preliminary display action ensures users can view and decide on the optimal crop region without losing access to any captured information.
2Area of stationary object
If the user crops a partial region from the taken photo, then the photo fits the display screen better, but the view angle is reduced and unseen regions are lost
Solution Approach 1:
The system provides dynamic switching between displaying the entire taken photo and displaying cropped regions. Users can freely adjust crop regions and switch between different display modes, allowing the view angle and displayed area to be dynamically adjusted according to user needs rather than being fixed.
Solution Approach 2:
Before finalizing any crop operation, the system displays the entire taken photo and allows users to preview all unseen regions. This preliminary display enables users to make informed decisions about cropping while having full awareness of the complete captured scene.
3Quantity of substance
If the mobile terminal stores only the cropped region, then the storage efficiency is improved, but the user cannot restore or view the original unseen regions later
Solution Approach 1:
The controller is configured to store both the cropped region and the original entire photo separately. This allows users to discard the cropped version when storage is sufficient, or recover the original unseen regions by accessing the stored entire photo whenever needed, providing flexibility in storage management without permanent information loss.

AI summary
Disclosed is a mobile terminal capable of restoring an unseen area, after taking a photograph, and a control method therefor. The mobile terminal, according to the present invention, can comprise: a camera for taking the photograph; a memory for storing data; a display unit for displaying, as a preview image, a partial area of an image inputted to the camera; and a control unit for taking the photograph of the entire image inputted to the camera when a photographing command is inputted, and controlling the partial area of the taken photograph to be displayed when a display command for the taken photograph is received. At this time, the control unit controls the entire area of the taken photograph to be displayed on the display unit when an editing command for the taken photograph is received, and can cut out a cropped area from the entire area of the taken photograph and store the same when the cropped area is set on the entire area of the taken photograph.
