Vehicle Display Mask Processing for Intuitive Spatial Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle display systems make it difficult for drivers to intuitively recognize the positional relationship or distance between their vehicle and surrounding vehicles or obstacles, as they display overhead images that are not directly visible, requiring complex brain processing for inference.
Innovation Solution
A vehicle display system that uses camera images and mask processing to generate a masked image, with semi-transparent vehicle body portions and lower transmittance windows, allowing drivers to easily recognize positional relationships and distances by displaying obstacles relative to the vehicle body, reducing the amount of information through the window.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If an overhead image is displayed to show surroundings of the vehicle, then the complete surrounding view is provided, but the driver cannot intuitively recognize positional relationship or distance with second vehicles or obstacles
Solution Approach 1:
The patent applies transparency changes (analogous to color changes) to different regions of the vehicle body in the displayed image. The vehicle body is divided into multiple regions with different transparency levels - the window region has lower transparency to reduce visual information, while other body regions have higher transparency to maintain positional reference. This allows the driver to intuitively recognize the position of second vehicles or obstacles relative to the own vehicle while reducing unnecessary visual information.
Solution Approach 2:
The patent applies different transparency properties to different local regions of the vehicle body. Specifically, the window region is assigned lower transparency to reduce the amount of visual information passing through, while other regions maintain higher transparency. This local differentiation helps the driver focus on critical positional information while filtering out redundant visual data, thereby improving intuitive recognition of spatial relationships.
2Loss of information
If the window region is made transparent to see through, then the driver can see external environment, but the amount of visual information increases making it harder to recognize positional relationships
Solution Approach 1:
The patent uses transparency adjustment (similar to color changes) to control the amount of visual information from different vehicle body regions. The window region is specifically assigned lower transparency to reduce the amount of external visual information that passes through, preventing information overload. This allows the driver to maintain focus on critical positional relationships without being distracted by excessive visual details from the window area.

AI summary
Disclosed is a vehicle display system (1) for displaying an image of surroundings of a vehicle. The vehicle display system (1) includes: a display (18a) configured to display an image thereon; a camera (4, 6, 8, 10) mounted on the vehicle and configured to image surroundings of the vehicle; and a display control unit (20) configured to subject an image captured by the camera to mask processing, using a mask image (MR, MF) including a semi-transparent portion (M3, M4, M14, M16) corresponding to a vehicle body, and a portion (M8, M18, M19) corresponding to a window of the vehicle and having a transmittance lower than that of the portion corresponding to the vehicle body, to generate a masked image (D), and cause the masked image to be displayed on the display.
