Vehicle Overhead Display Zoom Control for Door-Open Visibility
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 when the image is enlarged.
Innovation Solution
An image display device that synthesizes images from multiple cameras 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.
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 present outside the screen and cannot be displayed
Solution Approach 1:
The system continuously monitors door sensor states and uses this feedback to dynamically adjust the image display mode. When a door is detected as open, the system switches from enlarged view to full overview, ensuring the door state remains visible and can trigger appropriate alerts.
Solution Approach 2:
The display mode is made dynamic rather than static, automatically transitioning between enlarged and full overview modes based on real-time door sensor inputs. This allows the system to adapt its presentation to current vehicle conditions, optimizing both information completeness and user convenience.
2Measurement precision
If the overhead image is enlarged, then detailed view is provided, but the entire vehicle including all doors cannot be viewed
Solution Approach 1:
The system dynamically adjusts the displayed area based on door sensor states. When doors are closed, the enlarged view providing detailed information is displayed. When doors are opened, the system switches to a full overview mode that displays the entire vehicle, ensuring both detailed viewing and complete visibility are available as needed.
Solution Approach 2:
The display parameters (zoom level, visible area) are changed based on door state inputs. The system transitions between different display configurations - enlarged mode for detailed viewing when doors are closed, and full overview mode when doors are open - optimizing the balance between detail and completeness.

AI summary
An image display device (1) includes a camera (10) configured to image a periphery of a vehicle, a controller (12) 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 (10), a display unit (13) configured to display the overhead image output by the controller (12), and a sensor (11) configured to detect an opened state of a door of the vehicle. The controller (12) is configured to enlarge the overhead image and display the overhead image on the display unit (13), 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 (11).
