Dynamic Icon Sizing for On-Screen Display Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic devices with small displays, such as digital cameras and portable telephones, the on-screen display (OSD) function often results in poorly visible icons due to their small size, leading to potential erroneous settings as users struggle to confirm their settings, and increasing icon size can hinder the display of base image data or prevent all icons from being shown.
Innovation Solution
An electronic apparatus with a display unit that includes an apparatus-condition detecting unit, an icon assigning unit, and an on-screen-display controller, which detects changes in apparatus states or operating conditions, assigns icons differently, and displays them in a larger size when changed, allowing users to confirm settings without obstructing the base image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If icon size is increased to improve visibility, then character visibility is improved, but base image display is hindered and all icons cannot be displayed
Solution Approach 1:
The icon display system dynamically changes icon size based on detection results. When a detection result requires confirmation, the corresponding icon is enlarged to improve visibility. When no confirmation is needed, icons are displayed at normal size to maximize base image display area. This dynamic adjustment resolves the contradiction between icon visibility and base image display area.
Solution Approach 2:
The system changes the display parameter (icon size) based on the operational state. Icons are displayed at different sizes depending on whether confirmation is required for the current detection result. This parameter change allows the system to optimize visibility only when necessary, otherwise preserving maximum display area for the base image.
2Loss of information
If multiple icons are displayed on limited screen space, then all operating conditions can be shown, but individual icons become too small to see clearly
Solution Approach 1:
The system dynamically adjusts icon size based on the need for confirmation. When a detection result requiring confirmation is present, the corresponding icon is enlarged while other icons remain at normal or reduced size. This dynamic sizing ensures that all icons can be displayed on the limited screen space while the critical confirmation icon maintains sufficient visibility.
Solution Approach 2:
Different icons are displayed with different sizes based on their importance in the current context. The icon corresponding to the detection result requiring confirmation is displayed with higher quality (larger size), while other icons are displayed at normal or smaller sizes. This local quality differentiation ensures complete information display while maintaining visibility of critical elements.
3Illumination intensity
If icon size is increased to avoid garbled display, then character visibility is improved, but the number of displayable icons is reduced
Solution Approach 1:
The system dynamically adjusts the number and size of displayed icons based on operational context. When confirmation is required, the relevant icon is enlarged to prevent garbled display. When no confirmation is needed, all icons are displayed at smaller sizes to maximize the number of visible icons. This dynamic adjustment resolves the contradiction between character visibility and the number of displayable icons.

AI summary
An electronic apparatus with a display unit that can display icons indicating an apparatus state or an operating condition based on an on-screen display function includes an apparatus-condition detecting unit that detects a change of the apparatus state or a change of a setting of the operating condition; an icon assigning unit that assigns an icon indicating the apparatus state or the operating condition for which the change is detected by the apparatus-condition detecting unit; and an on-screen-display controller that displays the icon assigned in a shape different from the icon before being assigned.
