Split-Screen Video Display for Police Surveillance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cameras in police vehicles have a limited field of view, and existing omnidirectional cameras do not effectively display combined images from dual-lens devices without showing unimportant portions, which hampers comprehensive surveillance.
Innovation Solution
A dual-camera system comprising an omnidirectional camera and a narrow-view camera, coupled with a video processor and display module, captures and processes images to create combined images by removing unimportant portions and displaying them in a split-screen format, enhancing the field of view without unnecessary data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If an omnidirectional camera is used to capture images from all directions, then the field of view is expanded to 360 degrees, but the displayed images include unimportant portions that reduce clarity
Solution Approach 1:
The display screen is segmented into multiple regions, with different regions showing different camera feeds (omnidirectional camera feed, narrow-view camera feed, zoomed portions). This allows the system to present comprehensive surveillance coverage while maintaining clarity by selectively displaying only important portions in appropriate regions rather than showing the entire 360-degree view in a single distorted image
Solution Approach 2:
The system extracts and displays only the important portions of the omnidirectional image by allowing users to select and zoom in on specific regions of interest. The video processor identifies and enlarges relevant areas while cropping out unimportant portions, thereby maintaining image clarity while preserving comprehensive surveillance capability
2Adaptability or versatility
If a dual-lens device is used to capture both wide-angle and zoom images, then comprehensive coverage is achieved, but the complexity of processing and displaying the combined images increases
Solution Approach 1:
The system merges the feeds from multiple cameras (omnidirectional camera and narrow-view camera) into a single coordinated display. The video processor combines these different image sources and synchronizes them to work together, allowing comprehensive surveillance coverage while managing processing complexity through integrated handling of multiple image streams
Solution Approach 2:
The display configuration is made dynamic and adjustable. Users can selectively zoom in on different portions of the omnidirectional image, and the system dynamically adjusts which regions are displayed at what magnification levels. This dynamic adaptability allows the system to handle complex multi-camera feeds while maintaining ease of use through flexible, user-controlled display options

AI summary
A system includes a first camera operable to capture omnidirectional images and send omnidirectional-image data representing the omnidirectional images, a second camera operable to capture narrow-view images and send narrow-view-image data representing the narrow-view images, a video processor coupled to the first camera and the second camera and operable to form combined-image data using at least part of the omnidirectional-image data and the narrow-view-image data, and a display module interoperably coupled to the video processor and operable to display combined images from the combined-image data. The combined images each comprise a narrow-view-display portion and an omnidirectional-display portion.
