Smart IP Camera Color Night Mode Restoration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fixed mount surveillance cameras typically operate in day and night modes, losing chrominance information at night, resulting in only monochrome video recording, making it desirable to implement a smart IP camera with a color night mode to restore black-and-white night images to full color.
Innovation Solution
A smart IP camera equipped with both RGB and IR image sensors, utilizing a processor circuit to extract color features from day images and add color to monochrome night images using neural network models, storing and dynamically adjusting this information in a database to adapt to camera position changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If infrared illumination is used during night mode operation, then the camera can capture images in low light conditions, but chrominance information is significantly lost and only monochrome video is recorded
Solution Approach 1:
The system captures and stores color information from daytime images in advance, then applies this pre-captured color data to nighttime monochrome images during colorization processing, eliminating the need to capture color information during low-light conditions
Solution Approach 2:
The system creates a copy of color information from daytime reference images and applies it to nighttime monochrome images, generating a colorized version that replicates what the scene would look like in color without actually capturing color data during night mode
2Loss of information
If color information is extracted and stored in a database, then color night mode can be achieved, but the device complexity increases due to database storage and dynamic adjustment requirements
Solution Approach 1:
The system extracts only the essential color information from daytime images and stores it in a database, separating the color data from the complete image data to reduce storage requirements while maintaining colorization capability
Solution Approach 2:
Color information is extracted and stored in the database in advance during daytime operation, preparing the data structure and relationships beforehand to enable efficient colorization during night mode without complex real-time processing

AI summary
An apparatus includes a camera and a processor circuit. The camera may be configured to capture color images in response to visible light and monochrome infrared images in response to infrared light. The processor circuit may be configured to extract color features from the color images and add color to corresponding monochrome features detected in the monochrome infrared images.
