Thumbnail Thickness Recognition via Disproportionate Scaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing document management software applications fail to maintain the visual recognition of document thickness when resizing thumbnails, as the accompanying images that represent document thickness are reduced proportionally with the thumbnail size, making it difficult to discern the document's content and operability of binders is compromised.
Innovation Solution
An information processing apparatus with a display controller that controls the resizing of accompanying images in a manner where their thickness direction is maintained unchanged, while the other direction is resized with the display magnification, ensuring the visual recognition and operability of document and binder thumbnails are preserved during resizing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the thumbnail is reduced in size by using the display magnification function, then the display size of the thumbnail is reduced, but the thickness of the document is also reduced making it difficult to recognize document content
Solution Approach 1:
The patent applies local quality by differentiating the scaling behavior of different parts of the thumbnail. The document image is scaled according to the display magnification, while the accompanying image (thickness indicator) is scaled differently to maintain its visibility and informational value. This allows the thumbnail to be reduced in size while preserving the document thickness information through disproportionate scaling of the accompanying image.
2Area of stationary object
If the accompanying image is resized proportionally with the thumbnail, then the entire thumbnail is reduced in size, but the operability of binders is compromised
Solution Approach 1:
The patent implements local quality by applying different scaling factors to different components of the thumbnail. The accompanying image that represents binder thickness is scaled at a different rate than the overall thumbnail, ensuring it remains sufficiently large and visible for user interaction. This differentiated scaling maintains binder operability even when the thumbnail is reduced in size.

AI summary
An information processing apparatus includes a display controller that controls display of a display image, which is formed of a reduced image of a document by adding an accompanying image. The display controller controls display of the display image in a manner that when a display magnification of the display image is changed, the accompanying image is resized in a first direction in accordance with a magnification identical to the display magnification and resized in a second direction that differs from the first direction in accordance with a magnification that differs from the display magnification.
