Solution Overview
Problem
Existing methods for determining whether a click event occurs in an irregular image region within an image view are inefficient and inaccurate, often requiring complex operations and approximations to regular shapes.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If complex operations and approximations to regular shapes are used to determine click events in irregular image regions, then the determination can be performed, but the efficiency and accuracy deteriorate
Solution Approach 1:
The patent extracts the essential characteristic (color information) of the irregular image region and uses it for click event determination. Instead of dealing with the complex irregular shape directly, the solution extracts color data from pixels within the irregular region and compares click position colors against these extracted color characteristics, thereby simplifying the determination process while maintaining accuracy for irregular shapes
Solution Approach 2:
The patent changes the parameter used for click determination from geometric shape parameters to color information parameters. By comparing the color of the pixel at the click position with the color information of pixels within the irregular image region, the system achieves accurate click detection without needing to perform complex geometric calculations on irregular shapes
2Ease of manufacture
If irregular image regions are approximated as regular shapes for click event processing, then the processing becomes simpler, but the accuracy deteriorates
Solution Approach 1:
The patent creates a color information copy or representation of the irregular image region by extracting color data from its pixels. This color information serves as a simplified representation that retains the essential characteristics of the irregular region without requiring geometric approximation, enabling both simple processing and accurate click determination
Solution Approach 2:
The patent transitions from using geometric parameters (shape approximation) to using color parameters for click event determination. This parameter change allows the system to maintain the original irregular shape while achieving processing simplicity through color-based comparison
3Measurement precision
If color information comparison method is used for click event determination in irregular regions, then the accuracy improves, but the processing complexity increases
Solution Approach 1:
The patent performs preliminary action by extracting and storing color information from the irregular image region in advance. This pre-extracted color information is then used for rapid comparison during click event determination, avoiding the need for complex real-time calculations and reducing processing time while maintaining high accuracy
