Summary Image Generation for Home Security Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Home security systems lack efficient methods for generating and providing video summary information to users, and ensuring privacy in image transmission, especially after user authentication, which is crucial for managing and monitoring events in residential settings.
Innovation Solution
An image processing apparatus and method that includes a processor for analyzing captured images, generating summary images based on user requests or predetermined conditions, performing user authentication, and applying privacy functions to prevent arbitrary image transmission, featuring an image processing unit, authentication processing unit, and controller to manage image capture, analysis, and transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the home security system transmits all captured images to user terminals for monitoring, then the user can access complete event information, but the system generates excessive data transmission and storage requirements
Solution Approach 1:
The system extracts only the essential event information from captured images by detecting specific events (motion, color change, object appearance) and generating summary images that contain only the relevant portions, rather than transmitting all captured image data
Solution Approach 2:
The captured images are segmented into relevant event portions and irrelevant background portions, with only the event portions being transmitted to user terminals, thereby reducing overall data transmission while preserving essential event information
2Ease of operation
If the system provides unrestricted access to captured images after user authentication, then users can freely monitor events, but the system compromises user privacy and security
Solution Approach 1:
Different quality levels of image access are provided to different users based on their authentication status and authorization levels, with authenticated users receiving access only to event summary images rather than all captured images
Solution Approach 2:
The system introduces an authentication processing unit and controller as intermediaries between the image processing unit and user terminals, which mediate image transmission by filtering and authorizing what images are sent to which users
3Reliability
If the system continuously monitors and transmits all images, then complete event coverage is achieved, but energy consumption and processing load increase significantly
Solution Approach 1:
Instead of continuous image transmission, the system employs event-triggered periodic transmission where images are processed and transmitted only when specific events occur (motion detection, color change, object appearance), reducing energy consumption while maintaining reliable event monitoring
Solution Approach 2:
The image processing unit automatically detects events and triggers image generation and transmission only when necessary, eliminating the need for continuous manual monitoring and reducing overall system energy consumption
Data Source
AI summary
Provided is an image processing apparatus including at least one processor configured to implement: an image processing unit which receives at least one image captured by at least one camera, analyzing the captured image, and generates a summary image related to occurrence of an event among the captured image; and a controller which controls the image processor to generate the summary image in response to at least one of a user request received from a user terminal and a predetermined condition being satisfied.
