Vehicle Mirror Display With Head-Position Adaptive Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems fail to dynamically adjust the visible range according to the driver's head position, leading to inadequate viewing of desired areas around the vehicle, similar to the limitations of traditional rearview mirrors.
Innovation Solution
An image processing apparatus and method that uses a display unit and a mirror unit installed in the vehicle cabin, where the display unit displays images of the surrounding area and the mirror unit reflects this image, allowing the visible range to change with the driver's head position, mimicking the functionality of a rearview mirror.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a monitoring system simply displays an image acquired with an image capture device on a display device, then the system structure is simple, but the visible range is fixed and the driver is unable to move the range that may be viewed even if the driver moves his or her head position
Solution Approach 1:
The patent applies dynamics by making the visible range adjustable according to the driver's head position. The system dynamically changes the displayed image range based on detected head position changes, transforming a static display system into a dynamic one that adapts to driver movements, similar to how a rearview mirror allows variable viewing angles.
2Ease of operation
If the image is trimmed appropriately according to the change in head position, then the desired range can be displayed, but the image trimming position must change significantly with head position movement, which increases system complexity
Solution Approach 1:
The system dynamically adjusts the trimming position of the displayed image based on the driver's head position. When the head position changes, the control unit calculates the appropriate trimming position shift and updates the display accordingly, enabling flexible viewing without requiring complex mechanical adjustments.
Solution Approach 2:
The system uses feedback from the head position detection unit to continuously adjust the image trimming position. The detected head position information is fed back to the control unit, which then modifies the display parameters to maintain optimal viewing conditions, creating a closed-loop control system.

Function Achieved in This Case
Enables easy and effective viewing of the surrounding area by dynamically adjusting the visible range, improving the driver's ability to check desired areas without the limitations of fixed displays and side windows, such as fogging or raindrops.

AI summary
There is provided a vehicle display device (10) including a display unit (50), installed in a cabin of a vehicle and having a display face oriented in a different direction from a direction of a driver (DR), configured to display an image depicting a surrounding area of the vehicle, and a mirror unit (55) installed in the cabin of the vehicle and configured to reflect some or all of an image area displayed on the display unit (50). A visible range of the surrounding area visible to the driver (DR) through an image of the display unit (50) reflected in the mirror unit (55) changes according to movement of a viewing position of the driver (DR) with respect to the mirror unit (55).
