Image Trimming Apparatus with Automatic Face Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image trimming technologies do not allow users to easily adjust the magnification and angle of view to their preference, as they often fail to cover the desired angle of view when trimming images.
Innovation Solution
An image trimming apparatus that combines manual and automatic trimming indicators, using face information to allow users to adjust the trimming region, including a zoom and movement feature for precise trimming, and records the trimmed image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automatic trimming is used to quickly identify a trimming region, then the trimming operation speed is improved, but the trimming region may not cover the angle of view the user wants
Solution Approach 1:
The patent combines automatic trimming indication (based on face detection) with manual trimming indication capabilities into a single integrated system. The automatic trimming provides an initial trimming region that can be quickly identified, while the manual trimming allows the user to adjust the trimming region to achieve the desired angle of view. This merging of automatic and manual methods resolves the contradiction by providing both speed and user control.
Solution Approach 2:
The trimming region is designed to be dynamically adjustable. The system starts with an automatically determined trimming region and allows the user to dynamically modify it through manual operations. This dynamic approach enables the trimming region to adapt from an initial automatic state to a final user-customized state, resolving the contradiction between automatic speed and user control.
2Adaptability or versatility
If manual trimming operation is used to adjust the trimming region, then the user control over angle of view is improved, but the time required to indicate the trimming region increases
Solution Approach 1:
The system performs preliminary automatic trimming to establish an initial trimming region before the user performs manual adjustments. This preliminary action provides a good starting point that is already close to the desired result, reducing the amount of manual adjustment needed and thereby reducing the total time required while maintaining user control.
Solution Approach 2:
The system provides visual feedback by displaying both the automatic trimming indication and the manual trimming indication simultaneously. This feedback mechanism allows the user to see the relationship between the automatic result and their manual adjustments, enabling faster and more intuitive control with less time investment.
3Ease of operation
If only automatic trimming indication is provided, then the operation simplicity is improved, but the precision of the trimming region does not meet user requirements
Solution Approach 1:
The trimming indication system is designed to be dynamic, transitioning from an initial automatic state to a user-adjusted state. The system maintains operational simplicity by automatically providing an initial trimming region, then enables precision adjustment through manual operations. This dynamic approach preserves ease of operation while achieving high precision when needed.
Solution Approach 2:
The manual trimming indication acts as an intermediary between the automatic trimming result and the final desired trimming region. It provides a bridge that allows users to refine the automatic result with precise adjustments, maintaining both simplicity and precision in the trimming process.
4Manufacturing precision
If zoom and movement operations are added to adjust image size and position, then the precision of trimming region adjustment is improved, but the device complexity increases
Solution Approach 1:
The patent merges zoom indication and movement indication functionalities into the existing manual trimming indication framework. Rather than adding completely separate devices, the system integrates these adjustment capabilities into a unified manual trimming interface, reducing the increase in device complexity while maintaining high adjustment precision.
Solution Approach 2:
The manual trimming indicating device is designed with multi-functionality, serving as a universal interface for both zoom/movement adjustments and direct trimming region selection. This universal device performs multiple functions (zooming, panning, and trimming) through a single integrated mechanism, avoiding the need for multiple separate devices and thereby limiting the increase in complexity.
