Vehicle Image Processing Device for Direction-Aware Display Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for displaying a vehicle's surroundings from multiple viewpoints are inadequate as they require detection of a parking spot, limiting their applicability and passenger awareness during vehicle direction changes.
Innovation Solution
An information processing device with a detection unit, display control unit, and determination unit that generates and displays composite or generated images based on multiple camera inputs, adjusting the rear-to-front image proportion and viewpoint, to provide suitable visual patterns for passengers regardless of the vehicle's travel direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a composite image combining multiple camera inputs is displayed, then the rear of the vehicle is depicted with higher proportion, but the image complexity and processing requirements increase
Solution Approach 1:
The system segments the image display into two distinct modes: composite images that combine multiple camera inputs for comprehensive surroundings visibility, and generated images that use virtual viewpoints for specific scenarios. This segmentation allows the system to switch between detailed multi-camera composition and simplified single-camera processing based on operational needs, reducing overall system complexity while maintaining information completeness.
Solution Approach 2:
The system dynamically switches between composite image mode and generated image mode based on vehicle travel direction and operational conditions. When the vehicle is moving forward, the system uses generated images from single cameras; when reversing or in parking scenarios, it switches to composite images combining multiple cameras. This dynamic adaptation optimizes processing complexity according to actual information needs.
2Adaptability or versatility
If the system switches between composite images and generated images based on travel direction, then passenger awareness is enhanced, but the control system complexity increases
Solution Approach 1:
The information processing device performs multiple functions: it detects vehicle travel direction, determines appropriate image modes, processes both composite and generated images, and controls display switching. This multi-functionality is achieved through a single integrated control system that handles all these tasks, avoiding the need for separate specialized systems for each function and thereby managing complexity efficiently.
Solution Approach 2:
The system uses feedback from the detection unit about vehicle travel direction to automatically adjust the display mode. When the detection unit identifies reverse travel or parking conditions, it triggers the determination unit to switch from generated images to composite images. This feedback mechanism enables automatic adaptation without requiring complex manual control logic.
3Area of stationary object
If multiple cameras are used to generate composite images, then the coverage of vehicle surroundings is improved, but the data processing load increases
Solution Approach 1:
The system applies partial action by using only the necessary subset of cameras for each situation. For generated images during forward travel, it processes images from single cameras. For composite images during reverse travel or parking, it activates and processes images from multiple cameras. This selective processing avoids the excessive energy consumption that would result from continuously processing all camera inputs at full capacity.

AI summary
An information processing device includes a detection unit, a display control unit, and a determination unit. The display control unit switches a composite image to a generated image, and causes a display device to display the generated image when the determination unit determines that a predetermined condition has been satisfied under the state in which the detection unit has detected that a travel direction of a vehicle is backward.
