Webpage Image Resolution via Selective Data Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming technologies fail to acquire and display complete webpage data, often resulting in blank portions when selecting a range on a webpage, especially when using plug-in software or scripts, and screen shots do not provide high-resolution images due to resolution limitations.
Innovation Solution
A method involving a computer-readable medium with instructions to select and store webpage data from a display screen, generate first image data, detect image absence areas, and composite corresponding image data to fill these areas, producing composite image data that prevents blank portions in the selection area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If screen shot method is used to capture webpage images, then the complete webpage image can be acquired, but the resolution is limited by the monitor resolution and cannot achieve high resolution
Solution Approach 1:
The patent segments the image acquisition process into two parts: first acquiring the complete low-resolution image through screen shot, then acquiring high-resolution images only for the selected area through targeted data retrieval. This segmentation allows the system to combine the completeness advantage of screen shot with the high resolution advantage of targeted acquisition.
Solution Approach 2:
The patent performs preliminary screen shot to capture the complete webpage image structure and identify the selected area before performing high-resolution acquisition. This preliminary action allows the system to determine which specific regions need high-resolution treatment, avoiding unnecessary high-resolution capture of entire webpage.
2Adaptability or versatility
If plug-in software or scripts are used to display images on webpage, then the webpage functionality is enhanced, but the image data cannot be acquired resulting in blank portions
Solution Approach 1:
The patent introduces an intermediary image processing system that sits between the webpage display and the user. This intermediary captures the displayed image through screen shot, detects blank portions caused by plug-in or script limitations, and then retrieves or generates appropriate image data to fill these gaps, thereby recovering lost information.
Solution Approach 2:
The patent converts the harmful effect of blank portions (caused by inability to access plug-in or script image data) into a benefit by using screen shot to capture the overall layout first, then using the detected blank areas as targets for selective high-resolution acquisition or alternative image generation.
3Manufacturing precision
If the complete webpage data is acquired for high resolution, then the image resolution can be improved, but the data processing time and memory usage increase
Solution Approach 1:
The patent applies local quality by acquiring high-resolution images only for the selected area rather than the entire webpage. The system identifies the coordinates of the selected region and retrieves or generates high-resolution image data specifically for this local area, while other areas maintain lower resolution, thus optimizing both quality and processing efficiency.
Solution Approach 2:
The patent performs partial action by acquiring image data only for the necessary selected area rather than the excessive action of acquiring the entire webpage at high resolution. This partial acquisition significantly reduces data processing time and memory usage while still providing high resolution where needed.

AI summary
A non-transitory computer-readable medium having instructions to control a computer, which is configured to display a webpage including a webpage image based on webpage data, to perform a method of image forming control, the method including: receiving an instruction to select an area on the display screen as a selection area; storing selection area webpage data; storing first image data having a first format generated based on the selection area webpage data; storing image data having the first format representing the webpage image in the selection area, as a second image data; detecting an image absence area, wherein a content of the first image data display is absent from that of the second image data; generating correspondence image data corresponding to the image absence area; compositing the correspondence image data into the image absence area to produce composite image data; and outputting the composite image data.
