Image Distortion Correction via Visual Grid Mediator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image editing technologies require significant computational resources and user expertise to correct distortions in raster images, as they involve complex numerical value inputs and transformations, making it difficult for non-skilled users to achieve desired editing results, especially when dealing with distortions caused by optical systems.
Innovation Solution
An image processing content determining apparatus that generates a basic figure, superimposes a transformed image based on user instructions, and calculates the processing content to transform the image, allowing for intuitive and efficient correction of distortions such as aberration, keystone distortion, and tilt, using a pointing device for input and displaying transformed figures to assist user operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If numerical value designation and collective processing is used, then processing efficiency is improved, but ease of operation deteriorates due to requiring user expertise
Solution Approach 1:
The patent introduces a grid as an intermediary visual reference system between the user and the image processing operations. The grid provides a visual framework that mediates between the user's intuitive spatial understanding and the complex numerical transformations required for distortion correction, allowing non-expert users to perform precise adjustments without directly inputting numerical values.
Solution Approach 2:
The patent creates a visual copy or representation of the transformation process through the grid system. The grid lines are transformed alongside the image, providing a visual copy of the geometric operations being applied. This allows users to see and adjust the transformation parameters visually rather than through complex numerical inputs, improving ease of operation while maintaining processing efficiency.
2Ease of operation
If orthogonal grid transformation is used, then ease of operation is improved, but manufacturing precision deteriorates due to grid transformation along with image
Solution Approach 1:
The patent extracts the grid transformation from being strictly coupled with the image transformation. By allowing the grid to be independently controlled and adjusted, the system can separate the visual reference framework from the actual image processing operations. This enables precise distortion correction to be applied to the image while the grid serves as an independent visual guide, preventing the grid's simple transformation from limiting the precision of the image correction.
3Ease of operation
If trial and error method is used, then ease of operation is improved, but loss of time increases
Solution Approach 1:
The patent implements a feedback mechanism where the grid transformation provides immediate visual feedback about the distortion correction being applied to the image. As users adjust transformation parameters, the grid updates to show the effect in real-time, allowing users to make informed adjustments without repeated trial and error. This feedback loop reduces the time needed to achieve desired correction results while maintaining ease of operation through visual guidance.
