Vehicle Overhead Display Zoom Control for Door-Open Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display devices for vehicles struggle to balance the convenience of image enlargement with the need to alert occupants about the door-opened state, as the door's opened state may be displayed outside the screen during enlargement, leading to incomplete alerts.
Innovation Solution
An image display device that synthesizes peripheral images to create an overhead view, allows enlargement upon user request, and cancels enlargement when a door is detected as open, ensuring the entire vehicle remains visible and alerts are issued appropriately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the overhead image is enlarged and displayed, then the convenience for the occupant is improved, but the door-opened state may be displayed outside the screen and the alert function deteriorates
Solution Approach 1:
The display device dynamically adjusts the display mode between enlarged view and full vehicle view based on real-time door state detection. When a door is opened, the system automatically switches from enlarged display to full vehicle display, ensuring the door state remains visible and the alert function is maintained.
Solution Approach 2:
The system uses sensor feedback to detect door opening states and automatically adjusts the display accordingly. The detection unit monitors door states and provides feedback to the control unit, which then modifies the display mode to ensure both convenience and safety alert functionality are maintained.
2Measurement precision
If the overhead image is enlarged, then the detailed view is improved, but the overall vehicle context is lost
Solution Approach 1:
The display mode dynamically switches between enlarged detailed view and full vehicle context view based on door state. This dynamic adjustment allows the system to provide detailed views when needed while maintaining overall context visibility when safety requires it.
Solution Approach 2:
The system changes display parameters (enlargement level, display area) based on door state conditions. When doors are closed, higher enlargement parameters are used for detail visibility; when doors are opened, lower enlargement parameters are used to maintain overall context and safety alert functionality.

AI summary
An image display device includes a camera configured to image a periphery of a vehicle, a controller configured to output an overhead image in which the vehicle is viewed from a viewpoint above the vehicle, the overhead image being obtained by synthesizing images captured by the camera, a display unit configured to display the overhead image output by the controller, and a sensor configured to detect an opened state of a door of the vehicle. The controller is configured to enlarge the overhead image and display the overhead image on the display unit, and cancel the enlargement of the overhead image in response to the detection of the opened state of the door of the vehicle by the sensor.
