Vehicle Camera Angle View Switching Range Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in recognizing changes in the angle of view when switching between wide-angle and narrow-angle images displayed on a vehicle-mounted camera system, leading to impaired ability to discern the current angle of view, especially during brief distractions.
Innovation Solution
An image processing apparatus that performs range display processing for a predetermined time to differentiate between wide-angle and narrow-angle images, using techniques such as overlaying lines along the contour of the narrow-angle image or applying masking and unmasking processes to gradually change the image area, allowing users to recognize angle changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If images are switched between wide-angle and narrow-angle views, then the user can access different fields of view, but the user cannot readily recognize the current angle of view during switching
Solution Approach 1:
The patent applies visual differentiation techniques including overlaying lines along the contour of the narrow-angle image range and applying masking/unmasking processes to gradually change the image area. These visual changes help users recognize the current angle of view during switching, resolving the contradiction between providing multiple angle views and maintaining user awareness of the current view state.
2Reliability
If intermittent display of wide-angle image is used during narrow-angle display, then user can be notified of angle change, but user cannot intuitively discern whether image is switched to narrow or wide angle
Solution Approach 1:
The patent performs range display processing for a predetermined time before and after angle switching. This preliminary action of displaying the angle range information in advance allows users to intuitively understand whether the image will switch to narrow or wide angle, resolving the contradiction between notifying users of angle changes and enabling intuitive recognition of the switching direction.
3Loss of information
If range display is performed for predetermined time, then user can recognize angle change, but image switching response time increases
Solution Approach 1:
The patent applies masking and unmasking processes that gradually change the image area rather than completely obscuring it. This partial action approach maintains user recognition capability while minimizing the impact on switching response time, as the transition is smoother and less disruptive to the overall switching process.

AI summary
An image processing apparatus permits a user to readily recognize a current state of an angle of view. When an angle of view is switched from a wide-angle to a narrow-angle, range display is performed for a predetermined time prior to the switching. Range display includes a narrow-angle image frame formed with lines indicating a border of an image displayed for a predetermined time prior to the switching. After the predetermined time, a narrow-angle image is displayed and the range display is no longer displayed. The range display allows a user to readily recognize that the wide-angle image has been switched to the narrow-angle image by recognizing to what area in a pre-switching wide angle of view image the post-switching narrow-angle image corresponds.
