Electric Mirror Edge Overlay for Boundary Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric mirrors used in place of rear-view mirrors in vehicles do not provide a clear view of the vehicle's interior, making it difficult for drivers to distinguish between the captured image behind the vehicle and the surrounding environment, potentially leading to mistaken perception of the captured image as a front view.
Innovation Solution
A display control apparatus connected to an imaging apparatus that generates edge image data to clearly indicate the peripheral portions of the image viewed via the electric mirror, superimposing this data onto the captured image to create display image data, which is then controlled for viewing through the electric mirror.

Engineering Contradiction Analysis
1Measurement precision
If an electric mirror is used instead of a conventional rear-view mirror, then distant objects can be viewed clearly, but the driver cannot recognize the boundary between the captured image and the surrounding environment
Solution Approach 1:
The patent applies color changes by superimposing edge image data with distinct color characteristics onto the captured image. The edge detection component identifies boundaries and the superimposition component displays these edges with enhanced color contrast, making the boundary between the captured image and surrounding environment visually distinguishable while preserving the clarity of distant objects
Solution Approach 2:
The patent introduces an intermediary element (edge image data with distinct color characteristics) that mediates between the captured image and the surrounding environment. This intermediary edge detection layer acts as a visual separator that helps the driver distinguish the boundary without interfering with the primary function of viewing distant objects clearly

AI summary
A display control apparatus configured to be connected to an imaging apparatus is provided. The display control apparatus includes an obtaining unit configured to obtain image data captured by the imaging apparatus by capturing an image behind a vehicle; an edge image generation unit configured to generate edge image data that clearly indicates a peripheral portion of the image data to be viewed via an electric mirror that is placed at a rear-view mirror position inside the vehicle; a display image generation unit configured to generate display image data by superimposing the generated edge image data onto the obtained image data; and a control unit configured to control the generated display image data to be viewed via the electric mirror.
