Dashcam Event Playback Triggered by Display Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dashboard cameras require users to operate them or remove memory cards to reproduce event recording data, which can be cumbersome, especially in situations like accidents where users may be distracted or unfamiliar with the camera's functions.
Innovation Solution
A recording reproduction apparatus that includes a camera, event detection unit, recording controller, reproduction controller, display controller, and attachment/detachment detection unit, allowing for automatic storage and reproduction of event recording data when the device is detached from the vehicle, enabling easy access to accident footage without manual operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is required to reproduce event recording data, then data can be reproduced, but user convenience deteriorates when users are unfamiliar with the camera or distracted by accidents
Solution Approach 1:
The reproduction controller is pre-configured to automatically reproduce event recording data when detachment is detected, without requiring user initiation. This preliminary setup ensures that even distracted or unfamiliar users can access accident footage reliably by simply removing the device from the vehicle.
Solution Approach 2:
The system performs self-service by automatically detecting detachment and initiating reproduction of event recording data without human intervention. The dashboard camera serves itself by monitoring its own attachment state and autonomously executing the reproduction function when the display unit is removed.
2Ease of operation
If automatic reproduction is implemented upon detachment, then ease of operation improves, but device complexity increases due to attachment/detachment detection functionality
Solution Approach 1:
The reproduction controller serves multiple functions: it manages both normal recording operations and automatic reproduction triggered by detachment. The attachment/detachment detection unit integrates with the existing control system, allowing a single component to handle diverse functions without requiring entirely separate systems.
Solution Approach 2:
The attachment/detachment detection functionality is merged with the existing reproduction control system. Rather than adding a completely separate automatic reproduction system, the patent integrates detachment detection into the control logic that already manages recording and reproduction operations.
Data Source
AI summary
A recording reproduction apparatus according to the present disclosure includes: a captured data acquisition unit that acquires first captured data captured by a first camera that captures an image of an outside of a vehicle; an event detection unit that detects an event regarding the vehicle; a recording controller that stores the first captured data in a period including at least a timing of occurrence of the event as event recording data; a reproduction controller that reproduces the event recording data; a display controller that causes a display unit to display the event recording data reproduced by the reproduction controller; and an attachment/detachment detection unit that detects an attachment/detachment state of the display unit to/from the vehicle, in which the reproduction controller starts, when it has been detected by the attachment/detachment detection unit that the display unit has been detached from the vehicle, reproduction of event recording data.
