Map Thumbnail Video Signal Synthesis for Multi-Camera Position Association
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for monitoring multiple cameras struggle to concurrently display captured images in association with camera positions without distracting the user.
Innovation Solution
A system that generates a video signal to display thumbnail images of camera feeds on a map, allowing for sequential or split display of multiple camera images based on their positions, using a synthesis unit to associate camera positions with image display areas and manage streaming data through a network of cameras, routers, and servers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple camera images are displayed simultaneously on a map, then the user can monitor all camera positions, but the display becomes cluttered and the user cannot easily associate images with positions without averting their gaze
Solution Approach 1:
The patent divides the map display area into multiple image display areas, each associated with a specific camera position. When multiple cameras are monitored, the system splits the display into separate regions rather than showing all images in one area, allowing users to associate each image with its corresponding position on the map without visual clutter
Solution Approach 2:
The patent transitions from a two-dimensional arrangement of images to a three-dimensional spatial arrangement by associating images with their camera positions on the map in a vertical or layered manner. This allows multiple images to be displayed while maintaining clear positional association through the spatial relationship between the map and image display areas
2Area of stationary object
If thumbnail images of multiple imaging devices are displayed in the same area, then the display area is utilized efficiently, but the images become difficult to distinguish and associate with their respective positions
Solution Approach 1:
The patent applies different display qualities and characteristics to different regions of the map. Each image display area is locally optimized to show thumbnail images with clear association to its corresponding camera position, while other areas may show different information or remain empty, preserving position association without requiring uniform display across the entire map
3Ease of operation
If sequential switching of thumbnail images is used, then the display remains clear and position association is maintained, but the monitoring coverage is reduced compared to simultaneous display
Solution Approach 1:
The patent implements a dynamic display system that can switch between different display modes based on the number of cameras and user needs. When the number of cameras exceeds a threshold, the system dynamically transitions from simultaneous display to sequential switching, maintaining clear position association while adapting to different monitoring requirements and preserving productivity

AI summary
A captured image displaying device generates a video signal for causing a thumbnail image of a video taken by an imaging device to be displayed on a map. A synthesis unit generates a video signal for synthesizing and displaying a thumbnail image of a video of an imaging device in an image display area provided in association with an imaging position of the imaging device on a map. When there are imaging positions of a plurality of imaging devices in the image display area, the synthesis unit generates a video signal that causes thumbnail images of videos of the plurality of imaging devices to be switched and displayed in the image display area in a predetermined sequence, or generates a video signal that splits the image display area and causes the thumbnail images of the videos of the plurality of imaging devices to be displayed in split areas.
