Image State Detection for Optimal Object Trimming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing methods fail to ensure optimal trimming of objects in images when the angular field or orientation of the imaging device changes, leading to extraction of unintended objects.
Innovation Solution
An image processing device with an image state detection unit and a trimming-decision processing unit that detects changes in the image state and decides whether to perform trimming based on the detected state, preventing extraction of objects different from the user's intention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If trimming is performed based on focus position within angular field, then object extraction is automated, but wrong object may be extracted when angular field or orientation changes
Solution Approach 1:
The patent applies preliminary action by performing trimming decision processing immediately after focus determination processing, before any angular field or orientation changes can occur. The system detects the image state right after focus lock and makes the trimming decision based on this initial state, preventing subsequent changes from affecting the extraction accuracy. This timing strategy ensures that the trimming is based on the intended focus object rather than objects that may appear after device movement.
Solution Approach 2:
The patent implements feedback by introducing an image state detection unit that continuously monitors changes in the captured image state. When the detection unit identifies that the image state has changed (due to angular field or orientation changes), it feeds this information back to the trimming decision processing unit, which then adjusts or cancels the trimming operation. This feedback mechanism ensures that trimming decisions are dynamically adjusted based on actual image state changes, maintaining extraction accuracy.
2Productivity
If trimming decision is made immediately after focus lock, then processing speed is improved, but changes in image state may cause incorrect extraction
Solution Approach 1:
The system performs the trimming decision processing as a preliminary action immediately after focus lock is achieved, capturing the image state at this critical moment. This timing ensures that the trimming decision is made based on the intended focus object before any device movement or orientation changes can occur, thereby maintaining both processing speed and extraction accuracy.
Solution Approach 2:
The image state detection unit continuously monitors for changes in the captured image state and provides feedback to the trimming decision processing unit. If changes are detected after the initial trimming decision, the system can adjust or cancel the trimming operation, ensuring accuracy is maintained without significantly delaying the overall processing speed.
