Display Device Screen Capture Transparency Blurring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in applying image processing effects, such as blurring, across entire screens, especially in multi-window scenarios, due to hardware and software performance limitations.
Innovation Solution
A display device that captures a synthesized image comprising a video and graphic image, changes the data format to include transparency, transparentizes the video area, generates a second synthesized image with the transparentized video area, blurs this image, and displays at least a portion of the blurred image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If image processing effects such as blurring are applied to the entire screen including multi-window scenarios, then the visual effect quality is improved, but the hardware and software performance limitations cause processing complexity and computational load to increase
Solution Approach 1:
The screen is divided into multiple capture regions corresponding to different window positions. Each region is captured and processed independently, then synthesized together. This segmentation allows the blurring effect to be applied to the entire screen while managing computational complexity by processing smaller regions separately rather than the entire screen at once.
Solution Approach 2:
The patent introduces a new processing dimension by capturing screen regions in the display coordinate system and then transforming them to the window coordinate system for processing. This dimensional transformation enables efficient blurring application across multi-window scenarios by leveraging the structured relationship between display and window coordinate systems.
2Loss of information
If screen capture is performed to capture the entire synthesized image including video and graphic images, then the completeness of the captured image is improved, but the data processing load and memory requirements increase
Solution Approach 1:
Instead of capturing and processing the entire screen as a single large image, the patent segments the screen into multiple smaller capture regions corresponding to individual windows. Each region is captured, processed, and then synthesized. This reduces the memory footprint and processing load at any given time while maintaining complete coverage of the entire screen.
Solution Approach 2:
The patent performs preliminary actions by capturing screen regions in the display coordinate system before transforming them to the window coordinate system for processing. This preliminary capture in the display coordinate system ensures that all necessary image data is obtained before processing begins, preventing information loss while allowing efficient subsequent processing of segmented regions.
3Adaptability or versatility
If transparency elements are added to the data format to enable video area transparentization, then the flexibility of image processing is improved, but the data format complexity and processing overhead increase
Solution Approach 1:
The patent applies transparency selectively to specific video areas rather than the entire image. By identifying video regions and applying transparency elements only to those areas, the system achieves flexible image processing where transparency is applied locally where needed. This maintains processing efficiency by avoiding unnecessary transparency processing in graphic areas while still providing the adaptability to control video visibility independently.
Data Source
AI summary
A display device may include memory storing at least one instruction that, when executed by at least one processor, cause the display device to: obtain a first screen capture image having a first data format; change a data format for the first screen capture image from the first data format to a second data format comprising a transparency element; transparentize a video area associated with the first video image in the first screen capture image by adjusting a value of the transparency element for the video area; generate a second synthesized image based on a second screen capture image comprising the transparentized video area and the first video image or a second video image following the first video image; and blur the second synthesized image.
