Under-Display Imaging With Abnormality Detection for Clear Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses face challenges in capturing images effectively due to abnormalities on the display surface, such as fingerprints, hand oil, scratches, or bubbles between the display and protective films, which can result in foreign substances being in focus or affecting image quality.
Innovation Solution
An electronic apparatus is designed with a display unit, an imaging unit on the opposite side of the display surface, an abnormality detection unit to identify issues on the display surface, and a display control unit that highlights the abnormality and may display information urging its removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a camera module is disposed immediately below the display unit to capture images through the display surface, then the device can achieve a compact form factor with reduced bezel width, but image quality deteriorates due to abnormalities on the display surface such as fingerprints, hand oil, scratches, or bubbles
Solution Approach 1:
The abnormality detection unit performs detection before image capture to identify abnormalities on the display surface. The system proactively detects issues such as fingerprints, hand oil, scratches, or bubbles before they affect the image quality, allowing for preventive measures or corrections to be taken.
Solution Approach 2:
The system implements a feedback mechanism where the abnormality detection unit continuously monitors the display surface condition and provides information to the image capture process. When abnormalities are detected, the system can adjust capture parameters, notify the user, or retake the image to maintain image quality.
2Ease of manufacture
If the display surface is used as the imaging surface, then the device structure is simplified and manufacturing is easier, but measurement precision of image quality deteriorates due to foreign substances on the display surface
Solution Approach 1:
The abnormality detection unit performs detection before image capture to identify abnormalities on the display surface. The system proactively detects issues such as fingerprints, hand oil, scratches, or bubbles before they affect the image quality, allowing for preventive measures or corrections to be taken.
Solution Approach 2:
The abnormality detection unit acts as an intermediary between the display surface and the image capture process. It monitors the condition of the display surface and provides information that helps the system decide whether to proceed with image capture, adjust parameters, or notify the user to clean the surface.
