Under-screen Camera Image Quality via Display Content Subtraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional full-screen display devices pose challenges for under-screen cameras due to the impact of screen content on image acquisition, affecting imaging and face recognition quality, leading to poor user experience.
Innovation Solution
An image acquisition and processing method that involves determining the display state of a corresponding area on the screen and either acquiring images directly through a transparent area or processing images based on display content in a non-transparent area to minimize screen interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the camera is placed under the screen to achieve full-screen display, then the screen ratio is increased, but the image quality is degraded due to screen content interference
Solution Approach 1:
The system determines the display state of the first area before acquiring the image. If the area is in a non-transparent state (showing content), the system proactively acquires display information and prepares to process the image to remove screen content interference, rather than waiting for quality degradation to occur
Solution Approach 2:
The patent converts the harmful effect of screen content on image quality into a beneficial solution by acquiring display information about the screen content and using it to process the acquired image. The screen content that initially degrades image quality is now used as reference information to subtract and remove its interference from the final image, improving overall image quality
2Device complexity
If the camera is placed under the screen, then device integration is improved, but face recognition accuracy is degraded due to screen interference
Solution Approach 1:
The screen content that initially degrades face recognition accuracy is converted into useful information. The system acquires display information about the screen content in the first area and uses it to process the acquired image, subtracting the screen content interference and improving face recognition accuracy while maintaining the integrated under-screen camera design
3Ease of manufacture
If the camera is placed under the screen, then manufacturing simplicity is improved, but user experience is degraded due to poor image quality
Solution Approach 1:
The patent maintains the manufacturing simplicity of placing the camera under the screen while improving image quality by acquiring display information about the screen content and processing the acquired image to remove screen interference. This converts the manufacturing advantage into a viable solution that delivers acceptable image quality to users

AI summary
The present disclosure provides an image acquisition and processing method. The method includes acquiring an invoking event being configured to invoke an image acquisition device located under a display screen, an acquisition window of the image acquisition device corresponding to a first area of the display screen; activating the image acquisition device based on the invoking event; determining a display state of the first area; acquiring an image by using the image acquisition device based on the display state of the first area; and displaying the acquired image.
