Image Similarity Detection for Electronic Apparatus Layout Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic apparatuses face challenges in displaying images without issues, such as broken layouts, due to incomplete data or interactions between applications, which are difficult to detect and correct before shipping.
Innovation Solution
An electronic apparatus with a controller circuit and storage device that executes an image display program to detect user input, create images, and an image determination program to compare similarity between input information and stored images, outputting a result if the similarity degree falls below a threshold, indicating a potential layout issue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image display program is executed to display images based on user input, then image display functionality is provided, but image display issues such as broken layouts occur due to incomplete data or application interactions that are difficult to detect before shipping
Solution Approach 1:
The patent applies preliminary action by executing test input operations before the actual product is shipped. The image determination program runs predetermined input sequences to generate test images, which are then compared with reference images to detect potential display issues before the product reaches customers. This allows detection of broken layouts and other image display problems in advance.
Solution Approach 2:
The patent uses copying by creating reference images through the image display program using predetermined input information. These reference images are stored and later used for comparison with newly generated images. By copying the expected correct output, the system can automatically detect deviations that indicate image display issues without requiring manual inspection.
2Measurement precision
If similarity determination is performed between created images and stored reference images, then image display issues can be detected, but additional processing time and computational resources are required
Solution Approach 1:
The patent applies partial action by focusing the comparison process on specific critical regions or features of the images rather than analyzing every pixel. The image determination program identifies key areas where layout breaks or display issues are most likely to occur and concentrates the similarity determination on those regions, reducing overall processing time while maintaining detection accuracy.
Solution Approach 2:
The patent uses parameter changes by adjusting the threshold values and sensitivity parameters of the similarity determination algorithm. By optimizing these parameters, the system achieves accurate detection of image display issues while minimizing unnecessary processing. The parameter settings are tuned to balance measurement precision with processing efficiency.

AI summary
An electronic apparatus includes a controller circuit being configured to detect a first input information, the first input information being information input in an input device by a user, create a first image and display the first image on a display device, the first image being an image created based on the first input information, obtain the first input information and the first image, detect, from the storage device, second input information being same as the first input information, determine a similarity degree between the first image created based on the first input information and a second image in association with the second input information detected from the storage device, and where the similarity degree between the first image and the second image is smaller than a threshold, output a result that the similarity degree is smaller than the threshold.
