Vehicle Periphery Display Segmentation for Vertical Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle periphery displaying apparatuses face challenges in displaying wide-angle images captured by cameras with a horizontal field of view on vertically long display screens, leading to poor viewability due to the mismatch in image and screen dimensions.
Innovation Solution
A vehicle periphery displaying apparatus that includes an imaging device with a wide horizontal field of view, a vertically long display screen, and a display controller to arrange the vehicle periphery image and a part of the image one above the other in the vertical direction, allowing for easier visualization by adjusting the scale and position of the images on the display screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a wide angle camera with wide horizontal angle of view captures an image and a vertically-long-rectangular display screen is used, then the display screen can fit the instrument panel layout, but the displayed image becomes poorly viewable due to narrowing in the horizontal direction
Solution Approach 1:
The patent divides the horizontally long vehicle periphery image into multiple vertically arranged segments that fit the vertically long display screen. The image is segmented in the horizontal direction and arranged vertically, allowing the full width information to be displayed across multiple screen heights while maintaining the vertically long format required for the instrument panel.
Solution Approach 2:
The patent transforms the display approach by changing from a single horizontal arrangement to a vertical arrangement of multiple image segments. This dimensional reorganization allows a horizontally long image to be effectively displayed on a vertically long screen by utilizing the vertical dimension to represent horizontal image content.
2Reliability
If a vehicle periphery image is displayed on a display screen arranged in an instrument panel, then driver safety is improved by reducing viewpoint movement, but the image becomes difficult to view due to the vertically long shape of the screen
Solution Approach 1:
The patent segments the wide horizontal vehicle periphery image into multiple vertical sections that can be displayed on the vertically long instrument panel screen. This segmentation allows the complete periphery view to be maintained while adapting to the constrained vertical display format, ensuring both safety and viewability.
Solution Approach 2:
The patent implements dynamic image display where the system can switch between displaying the full segmented vehicle periphery image and displaying enlarged portions of specific areas. This dynamic adjustment allows drivers to view the complete periphery for safety while also being able to focus on specific areas of interest when needed.
3Area of stationary object
If a horizontally long image is displayed on a vertically long screen, then the screen utilization is optimized, but the image becomes distorted and poorly viewable
Solution Approach 1:
The patent resolves the shape mismatch by reorganizing the horizontal image content into a vertical arrangement. Instead of forcing the horizontal image to fit the vertical screen (which would cause distortion), the system uses vertical stacking of image segments to represent the horizontal field of view, effectively using the vertical dimension to display horizontal information.
Solution Approach 2:
The patent divides the horizontally long image into multiple segments that are arranged vertically on the screen. This segmentation preserves the aspect ratio and shape of the original image content while filling the vertically long screen area, avoiding distortion and maximizing screen utilization.

AI summary
A vehicle periphery displaying apparatus including an imaging device, a display device and a display controller is disclosed. The imaging device is configured to capture a vehicle periphery image with a wide horizontal filed of view. The display device includes a display screen, a dimension of the display screen in a vertical direction being larger than that in a horizontal direction. The display controller is configured to produce a predetermined-part image so that a part of the vehicle periphery image corresponds to the predetermined-part image. The display controller is further configured to cause the display device to display the vehicle periphery image and the predetermined-part image on the display screen such that the vehicle periphery image and the predetermined-part image are arranged one above the other in the vertical direction.
