Vehicle Display Overlay Timing for Rear-View Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices for vehicles struggle with user visibility as they separately display vehicle outside video from a rear camera and vehicle information, leading to potential impairments in visibility and user experience.
Innovation Solution
A display device configuration that includes a first receiver for vehicle information, a second receiver for vehicle outside images, and a processor to simultaneously display both images within a predetermined time, or display the outside image alone if vehicle information is not received in time, ensuring reliable and improved user visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If vehicle outside video and vehicle information are displayed separately, then real-time display of vehicle outside image is achieved, but user visibility is impaired
Solution Approach 1:
The patent merges the vehicle outside video and vehicle information into a single composite image displayed on one display device. The video processing unit overlays vehicle information (such as speed, navigation, or sensor data) directly onto the video feed from the rear camera, allowing both types of information to be presented simultaneously in an integrated manner that maintains real-time visibility while improving user comprehension and reducing visual search time.
2Illumination intensity
If vehicle information is processed and displayed simultaneously with vehicle outside image, then user visibility is improved, but display time may exceed predetermined time
Solution Approach 1:
The patent implements preliminary action by pre-processing vehicle information data and preparing it for overlay before the actual display moment. The video processing unit is configured to have vehicle information ready in advance, and the system prioritizes the integration process so that the combined image is generated and displayed within the predetermined time threshold, ensuring both improved visibility and timely response.
Solution Approach 2:
The patent applies the skipping principle by implementing real-time processing pipelines that rapidly integrate vehicle information with the video feed. The system uses efficient image processing algorithms and hardware acceleration to complete the overlay operation quickly, rushing through the processing steps to ensure the composite image is displayed within the required time frame without compromising the quality or completeness of the information integration.
3Loss of information
If separate display devices are used for vehicle information and vehicle outside video, then information clarity is maintained, but device complexity increases
Solution Approach 1:
The patent applies universality by designing a single display device and video processing unit that can handle multiple functions: displaying the raw video feed, overlaying various types of vehicle information (speed, navigation, sensor data), and adapting the composite display based on driving conditions. This multi-functional approach eliminates the need for separate dedicated display devices while maintaining information clarity through intelligent overlay techniques and prioritization of critical information.

AI summary
A display device mounted on a vehicle includes a display including a first region that displays a first image based on first image information in response to detection of a request for display of a vehicle outside image, and a second region that displays a second image based on second image information. The device receives first image information generated by a first device; receives, from a second device, second image information that is image information of a vehicle outside image; and simultaneously displays the first image and the second image in a case where the first image information is received within a predetermined time after the second image information is received, and displays the second image in a case where the first image information is not received even when the predetermined time elapses.
