Automatic Camera Frame Rate Adjustment for Flicker Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flickering issues in video capture due to mismatch between camera frame rate and power grid frequency, leading to inconsistent illumination and increased network and resource usage, are not effectively addressed by existing manual or software solutions, especially when cameras are used across different AC power grid frequencies.
Innovation Solution
An automated method that adjusts the frame rate of a video camera device based on the detected AC power frequency of the location, using a computing device to identify suitable frame rates and set the camera settings accordingly, eliminating the need for manual intervention or complex software processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If manual reset or software solution is used to address flickering, then flicker compensation is achieved, but device complexity and operational complexity increase
Solution Approach 1:
The camera device automatically detects its geographic location and adjusts its frame rate based on the local AC power frequency without requiring manual intervention or complex external software. The device serves itself by autonomously configuring the appropriate frame rate (25 fps for 50 Hz regions, 30 fps for 60 Hz regions) to eliminate flickering.
Solution Approach 2:
The invention changes the frame rate parameter of the camera based on the detected AC power frequency of the location. By dynamically adjusting this parameter (25 fps or 30 fps), the system eliminates flickering caused by mismatch between camera refresh rate and lighting frequency.
2Object-affected harmful factors
If manual reconfiguration of camera resolution is performed, then flicker compensation at higher resolutions is achieved, but ease of operation deteriorates
Solution Approach 1:
The camera device automatically detects its geographic location and adjusts its frame rate based on the local AC power frequency without requiring manual intervention or complex external software. The device serves itself by autonomously configuring the appropriate frame rate (25 fps for 50 Hz regions, 30 fps for 60 Hz regions) to eliminate flickering.
3Object-affected harmful factors
If frame rate is adjusted to match AC power frequency, then flickering is eliminated, but adaptability to different locations is improved
Solution Approach 1:
The camera system dynamically adjusts its frame rate based on the detected AC power frequency of the current location. The frame rate changes from 25 fps in 50 Hz regions to 30 fps in 60 Hz regions, allowing the camera to adapt to different geographic locations and eliminate flickering automatically.
Solution Approach 2:
The invention changes the frame rate parameter of the camera based on the detected AC power frequency of the location. By dynamically adjusting this parameter (25 fps or 30 fps), the system eliminates flickering caused by mismatch between camera refresh rate and lighting frequency.
4Ease of operation
If automated location-based frame rate setting is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The camera device integrates multiple functions into a single system: geographic location detection, AC power frequency identification, and frame rate adjustment. This universal approach allows the device to automatically adapt to different locations without requiring separate manual configuration steps or external software.
