App Picture Rendering for Aspect-Ratio-Safe Split Windows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The issue of picture stretching and compression occurs when users adjust the display ratio of windows in electronic devices displaying multiple applications simultaneously, affecting user experience.
Innovation Solution
The electronic device intercepts and corrects rendering instructions to maintain the aspect ratio of displayed pictures by recognizing the current scene and adjusting window sizes accordingly, using modules like the rendering instruction interception module and window monitoring module to prevent ratio changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the user adjusts the display ratio of a window in split-screen or floating window mode, then the window can be resized to fit different display needs, but picture stretching and compression occur affecting user experience
Solution Approach 1:
The patent introduces a rendering instruction interception module as an intermediary between the window manager and the graphics rendering system. This module intercepts rendering instructions before they are executed, allowing the system to detect when a window's display ratio is being adjusted and prevent the stretching/compression of pictures by modifying the rendering instructions accordingly. The intermediary layer enables window size adjustment while preserving picture aspect ratio integrity.
Solution Approach 2:
The system performs preliminary action by intercepting rendering instructions before the actual picture rendering occurs. When a window's display ratio is changed, the system captures the original rendering instructions, determines the appropriate picture region to display, and prepares corrected rendering instructions in advance. This preliminary intervention prevents picture distortion before it can affect the user experience.
2Manufacturing precision
If the electronic device intercepts and corrects rendering instructions to maintain picture aspect ratio, then picture stretching and compression are prevented, but the device complexity increases due to additional interception and correction mechanisms
Solution Approach 1:
The rendering instruction interception module is designed with multi-functionality to reduce overall system complexity. It serves multiple purposes: intercepting rendering instructions, detecting window display ratio changes, determining appropriate picture regions, and correcting rendering instructions. By consolidating these functions into a single module rather than separate components, the patent reduces the complexity that would otherwise arise from multiple independent systems working together.
Solution Approach 2:
The interception module operates autonomously within the existing rendering pipeline without requiring external intervention. It automatically detects when window display ratio adjustment occurs, identifies the affected picture regions, and corrects rendering instructions self-service fashion. This self-service capability eliminates the need for additional user actions or complex external control mechanisms.

AI summary
This application provides an application picture display method and apparatus, and an electronic device. The method includes: The electronic device displays a first window in response to a first operation performed by a user, and displays a first picture of a first application in the first window, where the first picture is obtained by rendering, the first window has a preset first aspect ratio, the first aspect ratio is a ratio of a width to a height of a visible region of the first window, and the first window is a window in a split-screen mode or a window in a floating window mode.
