Motorcycle Rear View Display Transitioning Between Focused and Wide Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image display systems for two-wheeled vehicles struggle to maintain a clear sense of distance and size of following vehicles, especially when displaying wide-range rear view images, leading to reduced visibility and difficulty in grasping the distance to the following vehicle.
Innovation Solution
An image display system that captures and displays a wide-range rear view image by transitioning between a standard image and a wider image area, with controlled magnification and user-operated screen switching, allowing riders to easily switch between different viewing areas and maintain a sense of distance and size of following vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a wide-angle lens is used to capture a wide range area behind the motorcycle, then the field of view is improved, but the size of the following vehicle in the image becomes small reducing visibility
Solution Approach 1:
The patent divides the rear view image into multiple selectable display areas (first area and second area). The control device allows switching between different area configurations, enabling the rider to choose between a focused view (first area) that maintains vehicle size perception and a wide-range view (second area) that expands field of view, thus resolving the contradiction between these two requirements.
2Area of stationary object
If the field of view is enlarged to display a wide range area, then the rider can check more area when changing lanes or turning, but the sense of distance to the following vehicle is lost
Solution Approach 1:
The patent implements a dynamic switching mechanism that allows the display to transition between different area configurations based on rider needs. The control device enables switching between the first area (maintaining distance sense) and the second area (expanding field of view), making the system adaptable to different riding scenarios such as lane changes versus general monitoring.
3Measurement precision
If the size of the following vehicle is increased in the display, then visibility is improved, but the field of view becomes narrow limiting the area that can be checked
Solution Approach 1:
The patent segments the rear view image into different displayable areas with different magnification levels. The first area provides enlarged view of the following vehicle for better visibility, while the second area provides wide-range view for broader situational awareness. The control device enables switching between these segmented views based on operational requirements.

AI summary
An image display system includes an image capture device that captures an image of an area behind a motorcycle; a display device that is disposed in front of a rider and displays an image based on image data obtained by the image capture device; and a control device which, when the motorcycle is travelling, controls the display device so as to display a first screen that displays a first image comprising a first area extracted from an imaging range of the image captured by the image capture device and, thereafter, transition from the first screen to a second screen that displays a second image comprising a second area, wider than the first area, extracted from the imaging range.
