Vehicle Display Control Using Motion-Based Angle of View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for displaying scenery outside a vehicle using vehicular cameras cannot increase the information amount of images related to desired regions based on vehicle motion states, and cannot enlarge display regions effectively.
Innovation Solution
A display control apparatus and method that acquires captured data from cameras, detects vehicle motion states, generates extracted image data using an angle of view set according to the motion state, and outputs display image data to a display unit with a preset image size, allowing for dynamic adjustment of image display based on vehicle speed and motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display region is enlarged to show more scenery information, then the information amount increases, but the display device physical size must be increased
Solution Approach 1:
The patent transitions from a 2D display plane to a 3D virtual space by generating a bird's-eye view image that synthesizes information from multiple camera angles. This dimensional transformation allows comprehensive scenery information to be presented within the original display area without physical enlargement, resolving the contradiction between information amount and display region size.
Solution Approach 2:
The patent embeds multiple pieces of information within a single integrated display by nesting the bird's-eye view image with additional overlays such as vehicle position indicators, surrounding vehicle information, and navigation data. This nesting approach maximizes information density within the fixed display area, achieving high information content without expanding the physical display region.
2Area of moving object
If the angle of view is increased to capture more scenery, then the coverage area increases, but the image resolution and quality deteriorate
Solution Approach 1:
The patent merges images from multiple cameras positioned at different locations and angles around the vehicle. By combining these multiple standard-resolution images into a synthesized bird's-eye view, the system achieves both wide coverage and maintained image quality, as each source image contributes a specific portion of the overall scene without requiring any single camera to have excessive wide-angle distortion.
Solution Approach 2:
The patent introduces an image processing and synthesis system as an intermediary between the cameras and the final display. This intermediary processes raw images from multiple cameras, performs geometric transformations, and synthesizes a coherent bird's-eye view that maintains image quality while achieving comprehensive coverage, thereby resolving the contradiction between coverage area and image quality.
3Loss of information
If multiple images are displayed to show different regions, then the information completeness improves, but the display complexity increases
Solution Approach 1:
The patent segments the complex task of displaying comprehensive scenery information into two parts: (1) image acquisition from multiple cameras, and (2) automated synthesis into a unified bird's-eye view. This segmentation allows the system to gather information from multiple sources while presenting it in a single integrated display, reducing the complexity of manual multi-image management while maintaining information completeness.
Solution Approach 2:
The patent implements an automated image synthesis system that self-manages the complex processing of multiple camera inputs. The system automatically performs geometric corrections, perspective transformations, and image merging without requiring manual intervention, thereby maintaining complete scenery information while minimizing the operational complexity for the user.
