Foldable Screen Image Cropping With Proportional Box Scaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image cropping methods on electronic devices require repetitive and tedious manual adjustments of the crop box, leading to suboptimal cropping effects.
Innovation Solution
An image cropping method and electronic device that utilize dual or folding screens to allow for simultaneous adjustment of the image and crop box size through proportional contraction or magnification via inputs on the secondary screen, followed by precise border line adjustments on the primary screen without altering the image's display position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the user manually adjusts the crop box position repeatedly to achieve fine cropping, then the cropping precision can be improved, but the operation complexity and time consumption increase
Solution Approach 1:
The patent introduces a dual-screen configuration where the first screen displays the original image and the second screen displays a magnified view of the crop box. This dimensional transition from single-screen to dual-screen allows users to perform precise cropping operations on the magnified second screen while maintaining context from the first screen, thereby improving cropping precision without increasing operational complexity
Solution Approach 2:
The patent divides the cropping operation into distinct phases: a coarse adjustment phase on the first screen and a fine adjustment phase on the second screen. By segmenting the cropping process into these two stages, the system enables precise cropping operations without requiring the user to repeatedly adjust the crop box position on a single screen, thus improving both precision and ease of operation
2Manufacturing precision
If the user repeatedly moves the crop box to achieve fine cropping, then the cropping effect is improved, but the time consumption increases
Solution Approach 1:
The patent utilizes a dual-screen setup where the second screen provides a magnified view of the crop box area. This allows users to perform fine cropping adjustments on the magnified second screen rather than repeatedly moving the crop box on the original first screen, significantly reducing the time required to achieve precise cropping results
Solution Approach 2:
The system performs a preliminary magnification action by displaying the crop box on the second screen at a larger size before the user performs fine adjustment operations. This preliminary magnification enables subsequent precise cropping operations to be completed faster and more efficiently, reducing overall time consumption while improving cropping quality

AI summary
An image cropping method includes: displaying a to-be-cropped image on a first screen, and receiving a first input performed on a second screen in a case that a crop box is displayed on the to-be-cropped image; in response to the first input and in a case that the relative position of the to-be-cropped image and the crop box is kept unchanged, adjusting the size of the to-be-cropped image and the size of the crop box according to the same contraction or magnification ratio; receiving a second input performed on a target border line of the crop box displayed on the first screen; and in response to the second input and in a case that the display position of the to-be-cropped image is kept unchanged, adjusting the position of the target border line and cropping the to-be-cropped image.
