Real-Time Shift Correction Preview for Image Composition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image processing methods, such as shift correction, require capturing and storing images before applying corrections, which can lead to unintended cropping and are inefficient for moving images, especially in film-making, where re-shooting is costly or impossible.
Innovation Solution
An image processing device that generates a preview image with applied shift correction in real-time, allowing users to preview effects before capturing, using a smaller-sized representation of the image for processing efficiency and applying the effect to the full-size image later, with options for automatic or manual control and remote processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If shift correction is applied to full-resolution images after capture, then correction quality is maintained, but the risk of inadvertent cropping increases and re-shooting becomes necessary
Solution Approach 1:
The patent applies shift correction to a lower-resolution preview image before the final image is captured. This preliminary action allows the composition to be adjusted in advance, ensuring that the final full-resolution image will not be cropped, thereby maintaining both correction quality and preventing cropping risks.
Solution Approach 2:
The patent creates a lower-resolution copy or representation of the scene for preview and correction purposes. This copy allows shift correction to be applied and evaluated without affecting the final high-resolution image capture, enabling verification of proper composition before the actual shot.
2Reliability
If shift correction is applied to moving images in real-time, then cropping risks are reduced, but processing complexity increases
Solution Approach 1:
The patent applies shift correction selectively to a lower-resolution preview portion of the moving image rather than processing the entire full-resolution video stream. This local application reduces processing complexity while still providing the necessary correction preview to prevent cropping issues.
Solution Approach 2:
The patent creates a simplified representation or copy of the moving image at lower resolution for real-time shift correction processing. This copy enables complex corrections to be computed and visualized in real-time without the computational burden of processing full-resolution video frames.
3Manufacturing precision
If shift correction is applied to full-resolution images, then final image quality is maintained, but processing time increases
Solution Approach 1:
The patent performs shift correction on a lower-resolution preview image before the final image capture. This preliminary correction allows composition adjustments to be made in advance, eliminating the need for time-consuming post-processing of full-resolution images and preventing the need for re-shooting.
Solution Approach 2:
The patent uses a lower-resolution copy of the image for shift correction processing. This copy allows the correction parameters to be computed quickly, and then these same parameters are applied to the full-resolution final image, significantly reducing processing time while maintaining image quality.
