Head-Up Display Video Processing for Drop-Frame Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-up display apparatuses face challenges in meeting varying display specifications due to inadequate hardware processing performance, leading to issues like drop frames during augmented reality displays.
Innovation Solution
A controller in the head-up display apparatus dynamically adjusts processing loads by monitoring preparation times and modifying display contents to ensure video data is prepared within predetermined cycles, reducing processing demands through methods such as data deletion or simplification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If display specification is increased through software update, then display quality is improved, but processing load increases beyond hardware capability
Solution Approach 1:
The system dynamically adjusts video data preparation strategies based on processing cycle timing. The controller monitors preparation time and adapts the level of video data processing (including selective deletion or simplification) to ensure completion within the fixed processing cycle, enabling flexible support for various display specifications within hardware limits
Solution Approach 2:
The system changes processing parameters (such as video data resolution, frame rate, or content selection) based on the calculated preparation time. When preparation time exceeds the processing cycle, the controller modifies display parameters or video data characteristics to reduce processing load while maintaining acceptable display quality
2Manufacturing precision
If complex video data is processed, then display quality is improved, but preparation time exceeds processing cycle
Solution Approach 1:
The controller calculates the preparation time required for video data before actual processing begins. Based on this preliminary calculation, the system determines whether to proceed with full processing or to apply simplification measures, allowing proactive adjustment to meet the processing cycle deadline
Solution Approach 2:
When full video data processing would exceed the processing cycle, the controller applies partial processing by selectively deleting or simplifying certain video data elements. This partial action approach maintains essential display quality while ensuring completion within the time constraint

AI summary
A head-up display apparatus and a method of processing video data, where the head-up display apparatus includes: a video display configured to display a video and to output video light of the displayed video; a video-light projector configured to project the output video light to a display region, thereby causing the projected video light to be visually recognized as a virtual image; and a controller configured to determine display contents, to prepare video data, and to cause the video display to display a video based on the data. The controller performs control to reduce a processing load required for preparing the video data such that the video data is completely prepared within a predetermined processing cycle. Alternatively, if a preparation time required for preparing the video data of tentatively-determined display contents before determining the display contents is longer than the predetermined processing cycle, the controller changes the tentatively-determined display contents.
