Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle video recording devices struggle to accurately capture and record videos in low luminance conditions, such as at night or in low light environments, leading to difficulties in identifying important information like vehicle number plates and surrounding states.
Innovation Solution
A vehicle video recording device equipped with a motion sensor, impact sensor, lamp controller, and controller that autonomously generates a light source by predicting impacts, adjusting luminance, and controlling vehicle lamps to enhance video recording quality in low light conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If video recording is performed in low luminance conditions without additional light sources, then the device structure remains simple, but video quality and information identifiability deteriorate
Solution Approach 1:
The patent reuses existing vehicle lamps (headlights, fog lights, turn signals) for their original illumination functions while simultaneously utilizing them as auxiliary lighting for video recording. This multi-functional approach provides additional lighting for the camera without requiring dedicated recording lights, thus improving luminance without significantly increasing device complexity
Solution Approach 2:
The system uses the vehicle's own existing lamp components to serve the video recording function. By controlling the vehicle's lamps to illuminate the scene for the camera, the system makes the vehicle's existing resources serve dual purposes, eliminating the need for separate recording-specific lighting hardware
2Illumination intensity
If vehicle lamps are controlled to illuminate for video recording, then video quality improves, but energy consumption increases
Solution Approach 1:
The system activates vehicle lamps periodically or intermittently based on recording needs rather than continuously. The controller determines when illumination is required for adequate video recording and activates lamps only during those periods, reducing overall energy consumption while maintaining video quality when needed
Solution Approach 2:
The system predicts potential impact events and activates lamps in advance before the actual recording event occurs. By using motion sensors and impact sensors to anticipate situations where video recording will be needed, the system prepares lighting conditions proactively, ensuring adequate illumination is available when recording starts without maintaining continuous lighting
3Measurement precision
If impact prediction is implemented using motion and impact sensors, then video recording accuracy improves, but device complexity increases
Solution Approach 1:
The patent integrates motion sensors and impact sensors with the existing video recording system and lamp control system. By merging these detection functions with the existing infrastructure, the system achieves improved impact prediction capability without requiring entirely separate systems, thus managing complexity through integration rather than addition
Solution Approach 2:
The system uses feedback from motion sensors and impact sensors to dynamically control video recording activation and lamp illumination. The sensors provide real-time information about vehicle motion and potential impacts, and the controller uses this feedback to automatically adjust recording and lighting, improving accuracy while automating the complexity management
Data Source
AI summary
A method for controlling a vehicle video recording device includes a step of transmitting a command to a lamp controller to operate a lamp in a case where an impact is predicted or an impact is sensed based on information sensed from a motion sensor and/or an impact sensor.
