Dual Image Capture Units with Asymmetric Pixel Counts for Processing Latency Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with multiple image capturing units face inefficiencies in image processing due to limited image sensor transmission rates and the need for extensive data analysis, leading to longer processing times and inadequate scene-specific processing methods.
Innovation Solution
Implementing a method where two image capturing units with different pixel counts capture images simultaneously, with the unit having fewer pixels outputting first to allow for immediate extraction of characteristic parameters, enabling timely determination of processing methods for both images, which are then synthesized and processed accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image analysis is conducted after the image is completely transmitted from the image sensor, then the processing can be comprehensive and accurate, but the processing time becomes longer and device efficiency decreases
Solution Approach 1:
The patent extracts characteristic parameter information from the first image during its transmission to the image processing unit, before the second image transmission is complete. This preliminary extraction enables early determination of the processing method, allowing the system to prepare processing algorithms in advance rather than waiting for complete image transmission, thus reducing overall processing time while maintaining analysis accuracy
2Manufacturing precision
If multiple image capturing units with high pixel counts are used to improve image quality, then the image quality improves, but the data transmission rate becomes a bottleneck and processing efficiency decreases
Solution Approach 1:
The patent divides the image capture task into two segments: the first image capturing unit uses fewer pixels to capture a lower-resolution image that is transmitted first and used for extracting characteristic parameters, while the second image capturing unit captures a higher-resolution image simultaneously. This segmentation allows the system to process images in parallel at different resolutions, using the faster-transmitting low-resolution image to determine processing methods, thereby improving overall processing efficiency while maintaining high image quality through the second unit
3Device complexity
If the electronic device uses limited pre-stored typical scenes to determine processing methods, then the device complexity is reduced, but the ability to handle special scenes is insufficient and post-processing load increases
Solution Approach 1:
The patent extracts characteristic parameter information from the first image and uses this feedback to dynamically determine the appropriate processing method for the current scene. This feedback mechanism allows the system to adapt to different scenes including special scenes without relying solely on pre-stored typical scenes, thereby improving scene adaptability while keeping device complexity low. The characteristic parameters serve as real-time scene descriptors that guide processing method selection
