Vehicle Image Recording Device with Dynamic Assistance Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image recording devices for vehicles face challenges in recording images effectively during assisted driving due to overlaid assistance images, which can obscure the vehicle surroundings, and the need for dedicated cameras increases costs.
Innovation Solution
An image recording device for vehicles that acquires surroundings images, displays overlaid assistance images during assisted driving, and records these images or processed images without visible assistance images when not in assisted driving mode, allowing for improved visibility and reduced costs by using existing cameras.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If assistance images are overlaid on surroundings images for driving assistance, then driving assistance functionality is improved, but the recorded image quality deteriorates because the assistance images obscure the vehicle surroundings
Solution Approach 1:
The patent applies dynamics by changing the state of the assistance image based on the recording mode. In normal driving assistance mode, the assistance image is displayed with full opacity to provide guidance. When recording mode is activated, the assistance image is dynamically adjusted to a transparent or semi-transparent state, allowing the surrounding environment to remain visible in the recorded image while still providing faint guidance information.
2Loss of information
If a dedicated camera is installed to capture images for the drive recorder, then the recorded image quality is improved, but the device cost increases
Solution Approach 1:
The patent applies universality by making the existing camera serve multiple functions. The same camera that captures images for the surround-view display is also used for drive recorder functionality. By controlling the transparency of assistance images during recording, the system eliminates the need for a separate dedicated camera, reducing device cost while maintaining adequate recording quality.
3Loss of information
If assistance images are made transparent or removed in recording mode, then the recorded image quality is improved, but the driving assistance effectiveness may be reduced
Solution Approach 1:
The patent applies local quality by differentiating the display characteristics in different regions or modes. In normal driving assistance mode, assistance images are displayed with full opacity for maximum guidance effectiveness. When recording mode is detected, the system locally adjusts only the transparency property of the assistance image overlay, while maintaining the same camera capture and processing pipeline, thus preserving assistance functionality while improving recording quality.

AI summary
An image recording device for a vehicle includes: an image acquisition section configured to acquire a surroundings image in which vehicle surroundings have been captured; an image display section configured to display an overlaid image in a display region inside a vehicle cabin in a case in which a predetermined assisted driving condition has been satisfied, the overlaid image being configured by an assistance image overlaid on the surroundings image acquired by the image acquisition section; and an image recording section configured to record the overlaid image at a recording section during an assisted driving state in which the overlaid image is being displayed in the display region, and, in a case in which the assisted driving state is not in effect, record at the recording section an image that has been subjected to image processing including processing to render a state in which the assistance image is not visible.
