IVI Display Control With Synchronized GUI Mode Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display control systems face challenges in accurately synchronizing images with layout changes due to time lags in processing, leading to potential desynchronization and limited animation expression.
Innovation Solution
A display control system that includes a generator to create a third GUI object with color information representing display mode, a renderer to generate an image based on this data, and a display controller to display the GUI object in the specified mode, ensuring synchronized image and layout changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the image integration unit waits for the application unit to generate images according to layout information, then the image quality and processing accuracy are improved, but the time lag increases and synchronization with layout changes deteriorates
Solution Approach 1:
The application unit generates images in advance based on current layout information before the image integration unit requests them. This preliminary generation allows the image integration unit to immediately use pre-generated images when layout changes occur, eliminating the time lag while maintaining image quality through proper rendering.
Solution Approach 2:
The system implements dynamic image generation where the application unit continuously generates images based on layout changes. When a layout change is detected, the system dynamically switches to using pre-generated images, creating a flexible response mechanism that balances image quality with synchronization timing.
2Reliability
If the application unit processes images with high quality rendering, then the display quality is improved, but the processing speed decreases and synchronization with layout changes deteriorates
Solution Approach 1:
The application unit performs high-quality image rendering in advance and stores these pre-rendered images. When layout changes occur, the system immediately uses these pre-prepared high-quality images, maintaining display quality while avoiding the time penalty of real-time rendering.
Solution Approach 2:
The system generates images with higher quality than immediately necessary, creating a buffer of pre-generated images. This excessive preparation ensures that when layout changes occur, high-quality images are readily available, trading some processing resources for improved synchronization and display quality.
Data Source
AI summary
A GUIApp of an IVI processor generates data of a third GUI object including a first GUI object and a second GUI object in which a numerical value related to a display mode of the first GUI object is set as color information. A GUI framework of the IVI processor generates an image of the third GUI object based on the data of the third GUI object. A video compositor of a meter processor displays the first GUI object in a mode based on the color information of the second GUI object included in the image of the third GUI object.
