Camera Frame Rate Control for Moving Object Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face challenges in detecting and shooting external objects at high speed accurately when using a single point of interest, often capturing unintended objects or failing to detect motion.
Innovation Solution
An electronic device with a processor that sets multiple points of interest and adjusts frame rates to capture moving objects, generating images based on their motion paths, allowing for high-speed shooting by switching between different frame rates and image sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single point of interest is used for high-speed shooting, then the frame rate can be increased, but the accuracy of detecting the intended external object decreases and unintended objects may be captured
Solution Approach 1:
The patent divides the monitoring area into multiple regions of interest (first ROI, second ROI, third ROI) instead of using a single point of interest. Each ROI is assigned to different cameras (first camera, second camera, third camera) to simultaneously monitor multiple areas. This segmentation allows the system to maintain high frame rates while improving object detection accuracy by distributing the monitoring task across multiple focused areas.
2Measurement precision
If multiple points of interest are monitored simultaneously, then object detection accuracy improves, but the system complexity increases
Solution Approach 1:
The processor serves multiple functions by simultaneously managing multiple cameras, multiple regions of interest, and multiple frame rates. The same processor that controls the first camera for the first ROI also controls the second and third cameras for their respective ROIs. This multi-functionality approach allows the system to monitor multiple areas with high detection accuracy without proportionally increasing system complexity, as the core processing unit handles all tasks.
Solution Approach 2:
Different regions of interest are assigned different frame rates based on their specific monitoring requirements. The first ROI is monitored at a first frame rate, while the second and third ROIs are monitored at a second frame rate. This local quality approach allows the system to optimize detection accuracy in each specific area while managing overall system complexity by applying different quality levels where needed.
3Adaptability or versatility
If different frame rates are used for different regions, then detection flexibility improves, but the control complexity increases
Solution Approach 1:
The system dynamically adjusts the frame rates for different regions of interest based on monitoring needs. The processor can switch between a first frame rate for the first ROI and a second frame rate for the second and third ROIs. This dynamic control allows the system to adapt to different detection scenarios and maintain flexibility while managing control complexity through automated processor management of the multiple frame rates.
