Client Device Image Selection and Display for Low Bandwidth Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current monitoring systems for public or private spaces using cameras struggle to efficiently display and manage subareas of video recordings, particularly in scenarios with large data volumes and low bandwidth networks, leading to latency and user dissatisfaction.
Innovation Solution
A client device with a screen and display device that allows users to select and display a desired image section from an image sequence by shifting and scaling the actual image section within an image coordinate system, using a communication device to request and receive the desired image section over a network, and displaying it correctly in the selected area, with the aid of metadata for precise positioning and scaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the entire video recording is transmitted and displayed, then the user can view the complete image, but the data transmission time and latency increase significantly
Solution Approach 1:
The image is divided into multiple selectable regions of interest (ROIs). Instead of transmitting the entire image, only the selected ROI is transmitted and displayed. This segmentation allows users to view specific areas of interest quickly, reducing transmission time and latency while maintaining image quality for the selected region.
2Measurement precision
If the image is scaled up to show more detail, then the visibility of subareas improves, but the network bandwidth requirement increases
Solution Approach 1:
The system extracts only the necessary subarea (ROI) from the complete image for transmission and display. By taking out only the relevant portion rather than transmitting the entire image, the system achieves high-detail visibility of the selected region while minimizing the data volume transmitted over the network.
3Adaptability or versatility
If multiple image sections are displayed simultaneously, then the user can compare different areas, but the screen space and complexity increase
Solution Approach 1:
The system implements a nested display structure where a thumbnail overview of the complete image is displayed, and users can click on specific regions to expand and view enlarged versions of those regions. This nesting approach allows multiple image sections to be displayed simultaneously in an organized manner, enabling comparison while maintaining manageable display complexity through hierarchical organization.

AI summary
The invention proposes a client device (2) having a screen (5), having a display device (6) for displaying a first image representation on said screen (5), wherein said first image representation shows an actual image section (9) in an actual selected range (10) from an image coordinate system Px, Py. The client device also has a selection device (7) which is designed to select a desired selected range (11) from the image coordinate system Px, Py, and a communications device (8) which is designed to request and receive a desired image section (12) of the desired selected range (11). The display device (6) is designed to display, in a second image representation, the actual image section (9) correctly in terms of position and size in the desired selected range (11) and, in an additional image representation, to display the desired image section (12) correctly in terms of position and size in the desired selected range (11), the actual image section (9) and the desired image section (12) coming from different images of an image sequence.
