Image Data Handling for UAV Bandwidth Constraints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in efficiently transmitting high-quality image data from movable devices like UAVs to remote devices due to bandwidth limitations, necessitating a method to process and store image data locally while providing real-time, lower-quality data for control purposes.
Innovation Solution
The system acquires high-quality image data, stores it locally, and generates reduced-size image data for transmission to a remote device, allowing for real-time control while preserving high-quality data for later use, using processors and storage devices integrated with imaging devices on movable objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high-resolution image data is transmitted to a remote device, then image quality is improved, but bandwidth consumption increases
Solution Approach 1:
The patent segments image data handling into two distinct pathways: local storage of full-resolution images and transmission of reduced-size preview images to remote devices. This segmentation allows the system to provide both high-quality images (locally) and bandwidth-efficient transmission (remotely), resolving the contradiction between image quality and bandwidth consumption.
Solution Approach 2:
The patent extracts only the essential visual information needed for real-time monitoring and control purposes, creating reduced-size preview images that contain sufficient detail for navigation and operation. This extraction approach maintains adequate image quality for control functions while dramatically reducing bandwidth requirements compared to transmitting full-resolution images.
2Measurement precision
If high-resolution image data is stored locally, then image quality is preserved, but storage requirements increase
Solution Approach 1:
The patent applies local quality by storing full-resolution, high-quality images locally on the electronic device where they are captured, while simultaneously providing reduced-quality preview images for remote access. This ensures that high image quality is preserved where needed (local storage) without unnecessarily consuming bandwidth or remote storage capacity.
3Measurement precision
If continuous high-resolution image capturing is performed, then image quality is maintained, but processing load increases
Solution Approach 1:
The patent implements partial action by processing only a subset of captured images into reduced-size previews for transmission, while the remaining high-resolution images are stored locally without further processing. This selective processing approach maintains image quality for all captured images while reducing the processing load associated with continuous high-resolution image handling.

AI summary
A method for handling image data of an electronic device includes an imaging device of the electronic device acquiring a plurality of images and continuing to acquire additional images after acquiring the plurality of images, and, while the additional images are continuously acquired by the imaging device, one or more processors of the electronic device storing first image data that correspond to the acquired plurality of images to a storage device of the electronic device, processing the plurality of images to generate second image data, and transmitting the second image data to a remote device. The second image data has a smaller data size than the first image data.
