Display Control Apparatus Superimposing Zoom and Enlargement Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies fail to explicitly express the relation between the region to be digitally zoomed and the region to be partially enlarged, making it difficult for users to understand the positional and size relationships during digital zoom and enlargement operations in imaging devices.
Innovation Solution
A display control apparatus and method that superimpose a first frame indicating the region to be digitally zoomed and a second frame indicating the region to be enlarged on the input image, allowing users to comprehend the relative positions and sizes of these regions through visual indicators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only a first frame indicating the digital zoom region is displayed, then the digital zoom region is clearly indicated, but the relation between the digital zoom region and the partial enlargement region cannot be expressed
Solution Approach 1:
The display is segmented into multiple functional layers: the through image serves as the base layer, the first frame (solid line) indicates the digital zoom region, and the second frame (dashed line) indicates the partial enlargement region. This segmentation allows each element to convey specific information without overwhelming the user, resolving the contradiction between providing complete region relation information and maintaining display simplicity.
Solution Approach 2:
The second frame acts as an intermediary element that bridges the information gap between the digital zoom region and the partial enlargement region. By introducing this intermediate visual indicator, the system enables users to understand the spatial relationship between different regions without adding significant complexity to the display interface.
2Loss of information
If multiple frames are superimposed to show region relations, then the relation between regions is clearly expressed, but the display becomes more complex
Solution Approach 1:
Different visual qualities are applied to different frames to enhance distinguishability: the first frame uses solid lines to indicate the digital zoom region, while the second frame uses dashed lines to indicate the partial enlargement region. This local differentiation in line style allows users to easily distinguish between the two regions and understand their spatial relationship without confusion, maintaining ease of operation despite the presence of multiple frames.
3Device complexity
If the non-imaging region is not displayed, then the through image is clean and simple, but the status of the non-imaging region cannot be observed
Solution Approach 1:
The first frame serves as a visual copy or representation of the digital zoom region's boundaries overlaid on the through image. This copied boundary information allows users to understand which region will be digitally zoomed without actually displaying the zoomed content, maintaining display simplicity while providing essential information about the non-imaging region's status.
