Spectral Edge RGB+IR Fusion

Unique low light performance tech for video surveillance systems

Leveraging our experience of the RGB and IR spectra, we’ve developed a unique IP product that dynamically fuses RGB+IR data in real time, generating the highest quality images expected for current high-grade security and video surveillance systems.

RGB + IR Fusion benefits

Our RGB+IR Fusion product is particularly beneficial during twilight periods because it optimises the effectiveness of all the data that has been captured. Instead of an arbitrary switchover point between visible and infra-red views, surveillance cameras powered by Spectral Edge’s RGB+IR Fusion combine both, maximising the resulting video quality and hence subject/object recognition capabilities.

Optimal video surveillance camera performance

Surveillance systems based on either visible light (RGB), or infrared (IR) capture, fail in certain light conditions:

During the day IR systems don’t collect any data even though it is present

At night, visible light systems don’t work without strong illumination

Systems configured to switch between the two fail to capture colour after the moment of switchover – resulting in lost information

Conventional security cameras capture either visible or IR data, not both concurrently. This restricts their ability to acquire detailed information in low/poor light, mixed lighting with under/over-exposed regions or misty/foggy conditions. Even high-end cameras comprising the latest RGB+IR sensors fail to maintain image quality in these situations. The knock-on effect is poor image quality, compromised subject/object recognition tasks and a high number of failure cases.

Integration

Our unique RGB+IR Fusion product has been designed to integrate with existing ISPs used by SoC manufacturers and can be implemented within the ISP, or as a pre-ISP solution. It can also be supplied as an end-to-end solution.
