Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with display capabilities face challenges in achieving high image quality due to limitations in capturing and processing optical signals, particularly in areas with varying light transmittance and resolution, which can result in defects like luminance, flare, and blur.
Innovation Solution
The implementation of a multi-camera module system under the display area, where each camera module receives optical signals from specific areas with different light transmittance and resolution, and an image processing method that corrects for defects such as luminance, flare, and blur by synthesizing data from multiple camera modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a single camera module is used under the display area, then the device structure is simple, but image quality is insufficient due to defects like luminance variation, flare, and blur
Solution Approach 1:
The single camera module is divided into multiple camera modules (first camera module and second camera module), each capturing images from different areas (first area and second area) of the display panel. This segmentation allows each module to specialize in capturing specific regions, reducing defects like luminance variation and flare in the final synthesized image
Solution Approach 2:
The patent introduces a new dimension by placing camera modules at different positions under the display area (different spatial locations). The first camera module is positioned to capture the first area while the second camera module captures the second area, creating a multi-dimensional capture system that overcomes the limitations of a single-position camera
2Loss of information
If camera modules capture optical signals from areas with varying light transmittance, then comprehensive image data is obtained, but defects like flare and luminance variation occur
Solution Approach 1:
The image processor performs image synthesis by combining data from multiple camera modules and applies correction algorithms to compensate for defects. The system uses feedback mechanisms where the synthesized image is processed to correct luminance variation and flare by referencing data from multiple sources, thereby improving overall image quality
Solution Approach 2:
The patent employs asymmetric positioning of camera modules and their corresponding capture areas. The first camera module and second camera module are positioned asymmetrically under the display area, each optimized for capturing specific regions with different light transmittance characteristics, allowing tailored optimization for each area's optical properties
3Manufacturing precision
If multiple camera modules are positioned to capture different areas, then image quality is improved, but the device structure becomes more complex
Solution Approach 1:
Multiple camera modules are merged into a single integrated electro-optical module assembly positioned under the display area. The first camera module and second camera module are combined in a coordinated arrangement, sharing common structural support and integration with the display panel, which manages the complexity while maintaining the benefits of multi-module capture
