Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging devices struggle to capture color images in low-light conditions, such as at night, due to the mixing of different infrared wavelengths, which hinders color reproduction performance.
Innovation Solution
The implementation of an imaging device with a first projection controller to selectively project infrared light with multiple wavelengths and a synchronous signal transmitter/receiver to synchronize the timing of infrared light projection between multiple imaging devices, allowing for synchronized infrared light projection and improved color image capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple imaging devices individually project infrared light with different wavelengths, then each device can capture color images, but the infrared lights mix together and prevent color image capture
Solution Approach 1:
Multiple imaging devices are merged into a coordinated system where each device projects infrared light with specific wavelengths simultaneously. The synchronization mechanism combines their operations so that all devices project in unison, preventing wavelength mixing while maintaining color image capture capability across the surveillance system.
Solution Approach 2:
A synchronization signal is transmitted from one imaging device to others, creating a feedback loop that coordinates the infrared projection timing. This feedback mechanism ensures all devices project infrared light at the same moment, preventing wavelength mixing and enabling successful color image capture.
2Ease of manufacture
If infrared light with multiple wavelengths is projected simultaneously, then color images can be captured, but the timing coordination between multiple devices becomes complex
Solution Approach 1:
The synchronization function is segmented into a separate, dedicated component that generates and transmits synchronization signals independently from the infrared projection function. This segmentation simplifies the overall timing coordination by isolating the synchronization logic, making it easier to implement and maintain while achieving precise wavelength timing.
Solution Approach 2:
A synchronization signal acts as an intermediary between the control systems of multiple imaging devices. This intermediary coordinate timing without requiring direct complex communication between all devices, simplifying the synchronization architecture while ensuring precise wavelength projection coordination.

AI summary
A first projection controller of an imaging device controls a first infrared projector, capable of projecting infrared light with multiple wavelengths, to selectively project the infrared light with the multiple wavelengths. An imaging unit of the imaging device images an object in a state where the first infrared projector projects the infrared light. A synchronous signal transmitter transmits outward a synchronous signal for synchronizing a timing of projecting infrared light from a second infrared projector controlled by a second projection controller included in another imaging device other than the imaging device, with a timing of projecting the infrared light from the first infrared projector controlled by the first projection controller.
