Dynamic Region of Interest Adaptation in Image Capture Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image capture devices require cumbersome manual processes to adjust regions of interest (ROIs) in dynamic scenes, leading to delays and missed opportunities due to changes in the scene, such as subject movement or changing lighting conditions.
Innovation Solution
An image capture device method that dynamically adapts ROIs by displaying real-time images, allowing users to select and set user-defined ROIs through touch gestures, and automatically resets to default ROIs when the device's position changes beyond a threshold or upon detecting a specific touch gesture, ensuring continuous optimal image acquisition parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual ROI adjustment is used, then user-defined regions can be set, but the process becomes cumbersome and causes delays in capturing dynamic scenes
Solution Approach 1:
The system dynamically switches between user-defined ROI mode and default ROI mode based on real-time detection of scene changes or device movement. The ROI configuration automatically adapts to current conditions without requiring manual intervention, resolving the contradiction between ease of operation and time loss.
Solution Approach 2:
The image capture device automatically detects when to switch between user-defined and default ROIs based on predefined conditions (scene changes, device movement thresholds). This self-service mechanism eliminates the need for users to manually reset ROI settings, reducing operational complexity and time delays.
2Adaptability or versatility
If user-defined ROI is set, then specific regions can be focused on, but the device cannot automatically adapt to changing scenes or positions
Solution Approach 1:
The system continuously monitors scene changes and device position through sensors and image analysis. When predefined thresholds are exceeded (e.g., device movement beyond threshold amount, scene changes), the system automatically provides feedback by switching from user-defined ROI to default ROI, enabling adaptive behavior without increasing user complexity.
Solution Approach 2:
The device pre-configures default ROI settings that automatically activate under specific conditions (device movement, scene changes). This preliminary preparation ensures that when changes occur, the system can immediately switch to appropriate default settings without requiring manual intervention, thus reducing operational complexity.
3Productivity
If automatic ROI reset is implemented, then delays are reduced, but the system must continuously monitor device position and scene changes
Solution Approach 1:
The system implements automatic ROI reset only for specific, pre-defined conditions (device movement beyond threshold, scene changes detected by sensors). This partial automation approach improves productivity for critical scenarios while avoiding the complexity of continuous monitoring for all possible conditions, achieving a balance between efficiency and system complexity.

AI summary
The present disclosure provides a method of dynamic region of interest adaptation and image capture device providing same. In one embodiment, there is a method of operating an image capture device. One or more regions within a real-time image may be used to set one or more user-defined regions of interest (ROIs) within the real-time image for applying one or more first image acquisition parameters. The one or more user-defined ROIs are cancelled and one or more default ROIs within the real-time image for applying one or more second image acquisition parameters are set when a position of the image capture device has changed by an amount which exceeds a threshold amount. Digital image data is acquired by the digital image sensor in accordance with one of the one or more user-defined ROIs and the one or more default ROIs.
