Vehicle Multi-Display Image Segmentation for Rendering Load Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information providing systems for vehicles face challenges in managing the display of application images across multiple onboard displays, leading to increased rendering processing loads and reduced visibility when the scale of collaboration exceeds the rendering capability, resulting in coarse images and inability to display divided images effectively.
Innovation Solution
An information providing system that controls the display mode by determining dividing areas for a zoomed-out application image to match the aspect ratios of multiple display areas, using a display change determiner and controller to adjust and display blocks accordingly, and dynamically adjusts based on driving information and frame rate to optimize image rendering and visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the number of onboard displays is increased to improve visibility of application images, then the viewability of application images is improved, but the rendering processing load increases
Solution Approach 1:
The patent divides the application image into multiple blocks corresponding to different display areas. The image processing device generates blocks that can be independently displayed on each onboard display, distributing the rendering workload across multiple devices rather than requiring one device to render the entire high-resolution image alone.
Solution Approach 2:
The patent transitions from displaying a single large-scale application image on one display to distributing divided blocks across multiple display areas in different spatial positions. This dimensional approach allows the system to leverage multiple displays' combined viewing area while distributing the processing burden.
2Area of moving object
If the scale of collaboration of multiple onboard displays is increased to display enlarged application images, then the viewability is improved, but the rendering processing load increases beyond the capability of the distributor
Solution Approach 1:
The application image is segmented into multiple blocks, each corresponding to a specific display area. This segmentation allows the rendering task to be distributed across multiple onboard displays with different capabilities, ensuring that no single device is overwhelmed while collectively achieving high-resolution enlarged display.
Solution Approach 2:
The system enables multiple onboard displays with different functions and capabilities to collaboratively display application images. Each display can show relevant blocks based on its characteristics, allowing the system to universally utilize all available display resources for enhanced viewing.
3Adaptability or versatility
If the application image is divided into blocks for multiple display areas, then the image can be displayed across multiple screens, but the image quality may become coarse if the division is not optimized
Solution Approach 1:
The patent determines dividing areas with aspect ratios matched to each specific display area's resolution characteristics. This local optimization ensures that each block is appropriately sized and proportioned for its target display, maintaining image quality while adapting to different screen geometries and resolutions.
Solution Approach 2:
The system dynamically adjusts the dividing area parameters based on the resolution and characteristics of each display area. By changing the aspect ratio parameters of dividing areas to match each display's resolution, the system maintains optimal image quality across different display configurations.

AI summary
An information providing system for vehicles is an information providing system for vehicles that controls a display mode of an application image to be displayed in a first display area and a second display area provided in a vehicle, and the information providing system for vehicles includes: a display change determiner that determines dividing areas for dividing an application image that is zoomed out, to obtain blocks that correspond, respectively, to the first display area and the second display area, such that the dividing areas have an aspect ratio equal to each of a resolution of the first display area and a resolution of the second display area; and a display controller that adjusts and displays the blocks divided in accordance with the dividing areas to correspond, respectively, to the first display area and the second display area.
