Vehicle Display Selective Image Data Rearward Passenger View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display systems for vehicles do not effectively integrate rearward view monitoring with passenger compartment imaging and speech detection to selectively display relevant regions or features, limiting their functionality and user interaction.
Innovation Solution
A display system comprising imagers and a controller that captures and processes image and audio data to selectively display a passenger's facial region or objects of interest based on detected speech or motion, allowing for hands-free operation and flexible display of rearward and interior views.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display system continuously displays the entire passenger compartment, then comprehensive monitoring is improved, but information relevance deteriorates due to displaying unnecessary regions
Solution Approach 1:
The system extracts and displays only the relevant region of interest within the passenger compartment based on speech detection, rather than displaying the entire compartment. The controller identifies the source of detected speech and selectively displays only that specific area, filtering out unnecessary visual information while maintaining monitoring effectiveness.
2Measurement precision
If the display system uses multiple sensors and processing units to detect speech and select regions, then display accuracy is improved, but device complexity increases
Solution Approach 1:
The display system is designed to perform multiple functions using integrated components: the imager captures both interior and exterior views, the microphone array detects speech from multiple directions, and the controller processes both visual and audio data to selectively display relevant regions. This multi-functional design improves accuracy without proportionally increasing complexity.
Solution Approach 2:
The controller acts as an intermediary that processes audio signals from the microphone array, identifies speech sources, and uses this information to selectively control the display of specific regions from the imager data. This intermediary processing layer coordinates the multiple sensors and enables accurate region selection while managing system complexity through centralized control.
3Adaptability or versatility
If the display system processes audio signals to detect speech sources, then user interaction capability is improved, but processing time increases
Solution Approach 1:
The system continuously monitors audio signals from the microphone array in real-time, maintaining readiness to detect speech sources without requiring full processing only when speech occurs. This preliminary monitoring approach enables quick response to user interactions while minimizing unnecessary processing time during non-interactive periods.

Implementation Method 1
a first imager configured to capture a first image data corresponding to an interior field of view of a passenger compartment of a vehicle
Implementation Method 2
a second imager configured to capture a second image data corresponding to a scene of objects exterior to the vehicle
Implementation Method 3
A display device may include a display screen configured to present visual information to a driver of the vehicle

AI summary
A display system for a vehicle is disclosed. The display system comprises a display device disposed in a passenger compartment of the vehicle. The display device comprises a screen. The display system further comprises a first imager configured to capture a first image data corresponding to a rearward directed field of view from the vehicle and a second imager configured to capture a second image data corresponding to a field of view of a passenger compartment of the vehicle. A controller of the display system is configured to display the first image data on a first portion of the screen and selectively display the second image data on a second portion of the screen in response to a detection of a display prompt.
