Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems fail to effectively determine changes in image capturing direction and calculate corresponding object position changes, leading to inadequate display of information related to object movement during image playback.
Innovation Solution
An image processing apparatus and method that includes a change determination unit to assess changes in image capturing direction, a change amount calculation unit to calculate position changes of objects, and an auxiliary image creation unit to generate data for displaying information on these changes, using data from multiple images captured continuously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional image processing is used without direction change detection, then the system is simple, but object position change information cannot be accurately determined
Solution Approach 1:
The image processing system is segmented into distinct functional modules: a direction change detection unit that analyzes capturing direction changes, and a position change determination unit that calculates object displacement. This segmentation allows each module to specialize in specific tasks, improving measurement precision while maintaining manageable system complexity through modular design.
Solution Approach 2:
An intermediary processing layer is introduced between raw image data and final position calculation. The direction change detection unit acts as an intermediary that preprocesses image data to identify capturing direction changes, which then informs the position change determination. This intermediary step enables accurate position measurement by accounting for camera movement, resolving the contradiction between precision and complexity.
2Loss of information
If auxiliary images are created to display object movement information, then information completeness improves, but processing time increases
Solution Approach 1:
The system performs preliminary detection of capturing direction changes during the image acquisition phase rather than during post-processing. By detecting direction changes as images are captured, the system prepares necessary information in advance, reducing the processing time required for auxiliary image generation while maintaining complete object movement information.
Solution Approach 2:
The system extracts only the essential information needed for auxiliary image display - specifically capturing direction changes and calculated position displacements - rather than processing all raw image data. This extraction approach minimizes processing time by focusing computational resources on critical movement parameters while still providing comprehensive object movement information in the auxiliary images.
