Control Visibility on Dynamic Backgrounds via HSV Parameter Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display methods on electronic devices face challenges in ensuring that controls are clearly visible against varying background pictures, particularly with bright or light-colored backgrounds, leading to abrupt contrast and potential difficulties for users with color discrimination disorders.
Innovation Solution
A method that determines the display parameters of controls based on the scene analysis of the background picture at their display position, ensuring a preset contrast condition is met, by analyzing HSV values and adjusting parameters such as saturation, value, and hue to maintain visibility and adapt to background changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a black gradient mask is added to the background picture to ensure control visibility, then the control contrast is improved, but the appearance quality deteriorates due to large black areas
Solution Approach 1:
The patent changes the color parameters (hue, saturation, value) of the control elements based on the background picture's color characteristics. By analyzing the background's HSV values and adjusting the control's display parameters dynamically, the system achieves good visibility without using black masks, thus maintaining appearance quality while ensuring reliability.
Solution Approach 2:
The system dynamically adjusts display parameters (brightness, contrast, saturation) of the control elements based on the background picture analysis. This parameter adaptation allows the control to maintain visibility across different background conditions without introducing harmful black areas, resolving the contradiction between reliability and appearance quality.
2Device complexity
If the control display parameters are fixed, then the device complexity is reduced, but the adaptability to different background pictures deteriorates
Solution Approach 1:
The system performs self-adaptation by automatically analyzing the background picture's color characteristics and adjusting its own display parameters accordingly. The control elements autonomously adapt to different backgrounds without requiring complex external configuration, achieving high adaptability while keeping the overall system complexity manageable through automated parameter adjustment.
Solution Approach 2:
The patent implements dynamic display parameters that automatically adjust based on the background picture. Instead of fixed parameters, the system continuously adapts control visibility parameters (hue, saturation, value) according to the background's color properties, enabling versatility across different backgrounds while managing complexity through systematic parameter adjustment mechanisms.
3Reliability
If the control color is adjusted to match bright backgrounds, then the visibility is improved, but the color consistency with brand identity may deteriorate
Solution Approach 1:
The patent applies different color adjustment strategies to different parts of the control interface based on the local background characteristics. By analyzing the background picture at the specific control display position and adjusting only the necessary color parameters locally, the system maintains visibility while preserving brand color identity in non-critical areas, thus resolving the contradiction between visibility and color consistency.

AI summary
This application provides a control display method and an electronic device. The method includes: determining a display position of a control on a background picture; and then determining a display scene of the background picture at the display position of the control, where the display scene of the background picture at the display position of the control is determined based on display parameters of the background picture at the display position of the control; determining display parameters of the control based on the display scene of the background picture at the display position of the control, so that a contrast between the background picture displayed at the display position of the control and the control displayed based on the display parameters meets a first preset condition; and displaying the control based on the determined display parameters of the control. This application is applicable to control display of the electronic device.
