In-Vehicle Camera Display Pre-Activation for Faster Video Startup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicular apparatuses face challenges in quickly displaying video captured by in-vehicle cameras due to the time required for controller activation, which can lead to delays in meeting safety standards like the KT Safety Act, and improving performance increases costs and processing capacity wastage.
Innovation Solution
The vehicular apparatus includes a controller unit and a communicator unit that acquires vehicle state signals to initiate the power supply and preparation for displaying video captured by the camera before the controller is fully activated, allowing for advanced activation of the camera and overlapping activation periods to quickly display the video.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the controller is activated in advance to prepare for video display, then the video display speed is improved, but the power consumption increases
Solution Approach 1:
The controller is activated in advance before the video display is actually needed, allowing it to complete its startup sequence and be ready to receive and display video data immediately when the display command is issued. This preliminary activation eliminates the delay that would otherwise occur during controller startup, achieving fast video display while managing power consumption by activating the controller only when anticipated to be needed based on vehicle state signals.
2Speed
If the controller performance is enhanced to reduce activation time, then the video display speed is improved, but the cost increases
Solution Approach 1:
Rather than enhancing controller performance to reduce activation time, the system uses preliminary action by activating the controller in advance based on vehicle state signals. This approach achieves fast video display using the controller's normal activation speed, avoiding the need for expensive high-performance controllers while still meeting the speed requirements through proactive activation timing.
3Speed
If the controller performance is enhanced to reduce activation time, then the video display speed is improved, but the processing capacity wastage increases
Solution Approach 1:
The system activates the controller in advance based on vehicle state signals rather than enhancing its processing speed. This allows the controller to complete its activation and be ready for video display using its standard processing capacity, avoiding the wastage that would result from having excessive processing power continuously available but not fully utilized during normal operation.

AI summary
A vehicular apparatus includes a controller unit configured to control a displaying operation of a video by a camera on a display and a communicator unit as an acquisition unit configured to acquire a vehicle state signal indicating a vehicle state. The controller unit is configured to perform a preparation for displaying the video by the camera on the display in response to the communicator unit acquiring the vehicle state signal indicating the vehicle state where the video by the camera is required.
