Image Depth Extraction for Multi-Camera Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face inefficiencies in processing depth information from multiple camera modules, leading to increased image processing demands and reduced user convenience due to unnecessary processing of depth information.
Innovation Solution
An electronic device with multiple image sensors and a processor that acquires and processes images to extract depth information from at least two subjects, generating a final image based on this information, allowing for efficient image processing and improved user experience by optimizing depth information extraction and image combination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If depth information is extracted from all subjects in multiple images, then depth information completeness is improved, but image processing complexity increases
Solution Approach 1:
The patent extracts only the necessary depth information for specific subjects of interest rather than processing all subjects in the image. The processor identifies target subjects and extracts depth information selectively, removing unnecessary processing steps while maintaining the required depth information for the final image.
2Measurement precision
If depth information is extracted from multiple camera modules, then depth information accuracy is improved, but processing time increases
Solution Approach 1:
The patent segments the depth information extraction process by dividing it into distinct stages: acquiring multiple images from camera modules, extracting depth information from specific subjects in each image, and synthesizing the final image. This segmentation allows parallel processing of different subject depth extractions, reducing overall processing time while maintaining accuracy.
Solution Approach 2:
The patent performs preliminary identification of subjects of interest before extracting depth information. By pre-selecting which subjects require depth extraction, the system avoids unnecessary processing of all subjects, thereby reducing processing time while ensuring accurate depth information is obtained for the required subjects through multiple camera modules.
