Solution Overview
Problem
Existing image extraction methods fail to accurately determine the priority of moving-image constituting images for display, as they do not consider the actual state of the subject, making it difficult to output the images that users want to appreciate.
Innovation Solution
An image extracting apparatus and method that computes the acceleration of objects within moving images to identify key moments, allowing for the extraction of representative images based on predetermined reference accelerations, and specifies timing for extracting moving-image constituting images within a centered time range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automatic determination of priority is performed without considering actual subject state, then processing complexity is reduced, but extraction accuracy of representative images deteriorates
Solution Approach 1:
The patent changes the parameter used for priority determination from button operation state to object acceleration state. By computing acceleration based on position changes in continuous images and comparing it with reference acceleration, the system automatically identifies crucial moments without manual input, thereby improving both automation extent and extraction accuracy simultaneously.
2Ease of operation
If button grabbing is used to estimate captured image state, then user operation is simplified, but reliability of representing actual subject state deteriorates
Solution Approach 1:
The system performs self-service by automatically computing object acceleration from image sequences without requiring user input. The object extracting section automatically identifies objects, the acceleration computing section calculates their motion, and the timing specifying section determines crucial moments, eliminating the need for button grabbing while reliably representing actual subject state.
3Quantity of substance
If all moving-image constituting images are output, then completeness of output is improved, but information overload and user appreciation quality deteriorates
Solution Approach 1:
The patent extracts only the most significant moving-image constituting images by identifying timing when object acceleration exceeds reference acceleration. This selective extraction removes irrelevant images while preserving crucial moments, preventing information overload and maintaining high quality for user appreciation.
