Vehicle Image Display Controller Mode Switching Reference Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display apparatuses for vehicles can cause user misunderstanding when switching between standard and wide angle views, as the size of objects appears to change due to differences in imaging ranges, leading to misinterpretation of object distance.
Innovation Solution
An image display apparatus with a display controller that switches between standard and wide angle modes, clearly indicating the area corresponding to the standard image on the wide angle image through visual cues like brackets, frames, or contrast changes, to prevent misinterpretation of object distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display controller switches to a second display mode showing a wider range (second image), then the imaging range is improved, but the object size decreases causing user misunderstanding of distance
Solution Approach 1:
The patent introduces a reference indicator (frame or bracket) as an intermediary element that mediates between the wide-angle image and the user's distance perception. This indicator visually marks the boundary of the standard image area within the wide-angle view, serving as a reference that helps users understand the relationship between the two imaging ranges and maintain accurate distance perception despite the change in object size
Solution Approach 2:
The patent applies visual differentiation through color or luminance changes to the reference indicator (frame or bracket) to make it clearly distinguishable from the background image. This visual emphasis ensures that users can easily identify the reference marker and use it as a reliable cue for understanding spatial relationships and maintaining accurate distance perception when viewing wide-angle images
2Area of stationary object
If the display controller switches from first image to second image showing broader range, then the field of view is improved, but object size perception becomes inaccurate
Solution Approach 1:
The reference indicator acts as an intermediary that bridges the gap between the wide-angle view and accurate size perception. By displaying a frame or bracket that outlines the standard image area, users can visually compare object sizes relative to this reference, thereby maintaining measurement precision for object size despite the expanded field of view
Solution Approach 2:
The patent adds a new visual dimension by superimposing a two-dimensional reference indicator (frame or bracket) onto the wide-angle image. This additional visual layer provides a spatial reference framework that helps users mentally reconstruct accurate object sizes and distances, effectively compensating for the distortion caused by the wide-angle perspective

AI summary
An image display apparatus is provided with: an imager configured to image a scene in surroundings of a vehicle; a display configured to display a captured image imaged by the imager; and a display controller configured to switch between a first display mode in which a first image is displayed and a second display mode in which a second image is displayed, wherein the first image is the captured image showing a first range out of the surroundings of the vehicle, and the second image is the captured image including at least a part of the first range and showing a second range, which is wider than the first range, out of the surroundings of the vehicle. The display controller displays the second image on the display in the second display mode in an aspect of clearly showing an area of the second image corresponding to the first image.
