Web Browser Image Resolution Selector for Visual Accessibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional web browsers do not provide a direct method for users with visual impairments to access higher resolution images within the same web page, leading to grainy images when magnification is applied without resolution adjustment.
Innovation Solution
A method that identifies and provides access to alternate image versions within an electronic document, allowing users to select and display larger, higher resolution images through a selector, with corresponding reformatting of the document.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If web browsers magnify portions of web pages including images, then users can see larger images, but the image quality becomes grainy due to lack of resolution adjustment
Solution Approach 1:
The system dynamically switches between multiple image resolutions based on user selection. Instead of static magnification that degrades quality, the browser provides dynamic access to pre-prepared high-resolution versions of images, allowing the display size and resolution to adapt together maintain sharp picture quality
Solution Approach 2:
The system changes the resolution parameter of images by providing access to multiple pre-rendered versions with different resolutions. When a user needs higher quality, the system switches from displaying a low-resolution image to a high-resolution image, thereby changing the resolution parameter without degrading image quality
2Manufacturing precision
If users access higher resolution images through links to alternate web pages, then image quality improves, but navigation complexity increases and time is lost
Solution Approach 1:
The system merges multiple image resolutions into a single web page display. Instead of requiring users to navigate to separate pages for different resolutions, all resolution versions are integrated into the same page, allowing users to switch between them using a selector without leaving the current page context
Solution Approach 2:
The system introduces an image selector as an intermediary component that mediates between the user and multiple image resolutions. This selector provides a simple interface for users to choose their preferred resolution without requiring complex navigation through multiple pages or directories
3Manufacturing precision
If users access higher resolution images through links to alternate web pages, then image quality improves, but access time increases
Solution Approach 1:
The system performs preliminary action by pre-rendering and storing multiple resolution versions of images on the server before user request. When users need high-resolution images, these are already prepared and can be delivered quickly without requiring time-consuming real-time processing or navigation to separate pages

AI summary
A method, program and apparatus for providing access to alternate images in an electronic document are provided. The present invention comprises identifying an initial image to be displayed in an electronic document (typically a web page) and then determining if alternate versions of the image are available for display. If alternate versions of the image are available, they are provided within the same electronic document. The alternate images differ from the initial image in size and resolution, allowing users with visual impairments to access larger, higher resolution images. The user accesses the alternate images by means of a selector displayed within the electronic document. When selected, the alternate image replaces the initial image in the electronic document, and the document is reformatted.
