Electronic Device Image Distortion Correction Position Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users experience a strange feeling when switching from viewing a portion of an image captured with a fisheye lens to the same portion after distortion correction, as objects at the same coordinates in the two images may differ significantly.
Innovation Solution
An electronic device with a processor and memory that performs an acquisition process of acquiring a first image and a second image corrected for distortion, and an adjustment process to maintain the display position of objects after switching between display modes, ensuring objects remain at the same position before and after correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If distortion correction is applied to fisheye images, then image quality and viewing experience are improved, but object position consistency deteriorates when switching between original and corrected views
Solution Approach 1:
The patent introduces coordinate transformation as an intermediary mechanism between the original fisheye image coordinates and the corrected image coordinates. By establishing a mapping relationship through coordinate transformation, the system can identify corresponding objects across different views and adjust display positions to maintain object location consistency, thus resolving the contradiction between distortion correction and position stability
Solution Approach 2:
The patent dynamically adjusts display parameters (position coordinates) based on the transformation relationship between original and corrected images. By changing the display position parameter according to the coordinate mapping, the system maintains object position consistency while still applying distortion correction to improve image quality
2Adaptability or versatility
If display mode switching between original and corrected images is enabled, then user flexibility and adaptability are improved, but user comfort deteriorates due to position shifts
Solution Approach 1:
The patent uses coordinate transformation as an intermediary to bridge the original and corrected image views. This intermediary mechanism enables smooth transitions between display modes by calculating corresponding positions through coordinate mapping, thereby maintaining user comfort while providing display mode flexibility
Solution Approach 2:
The patent performs preliminary coordinate transformation calculations to determine the display positions of objects in the corrected image before actual display mode switching occurs. This preliminary positioning ensures that when users switch between modes, objects appear at consistent locations, maintaining user comfort while enabling flexible display options

AI summary
An electronic device acquires a first image, and a second image that is an image obtained by applying a geometric transformation to the first image to reduce distortion. The electronic device switches display modes between a first mode of displaying an area of the first image in a display region, and a second mode of displaying an area of the second image in the display region. When switching the display modes, the electronic device adjusts a display position of an image that is displayed in the display region after the switching of the display modes such that an object located in a first position in the display region before the switching of the display modes will be located in the first position after the switching of the display modes.
