Dahua Technology, a world-pioneering video-centric AIoT solution and service provider, has proudly released the WizColor technology that seamlessly combines powerful AI-ISP, a large pixel size sensor and F1.0 large aperture features in one camera. 

This unique integration enables cameras to effortlessly capture high-quality images with vibrant colors during nighttime, ensuring fine details are preserved and minimising motion blur in the image.

Image processing algorithm

The WizColor technology offers abundant features and intelligent functions. It utilises a high-performance AI-ISP chip that increases visual model processing efficiency by 40%, and reduces power consumption by 30%. 

The AI-ISP deep image processing algorithm provides 50% increase in detail restoration and 80% reduction in motion blur. It is also equipped with a billion-level model training that provides billion-level scenarios library, 50+ visual training networks, as well as 30+ categories of extreme scenario algorithms.

WizColor’s F1.0 aperture

The amount of incoming light from WizColor’s F1.0 aperture is 2.5 twice that of F1.6 aperture

In addition, its F1.0 larger aperture absorbs a higher amount of light, enabling the WizColor camera to capture more vivid and brighter images under lowlight conditions. In fact, the amount of the incoming light of WizColor’s F1.0 aperture is 2.5 twice the amount of F1.6 aperture.

What’s more, its large pixel size sensor also means that more photons can be received and converted into stronger electrical signals. This greatly enhances the signal, resulting in an image with higher brightness and lower noise.

Handful of notable benefits

In terms of image quality, the WizColor technology brings a handful of notable benefits to users, including

  • Accurate and Clear Details: WizColor restores image details by 50%. Its AI-ISP detects image noise (and other relevant target information) and effectively reduces it accordingly using its precise pixel-level denoising algorithm.
  • More Realistic Colour Images: It restores image colour by 30%, and offers excellent colour denoising capability. Images with more precise colours can extract more accurate target information.
  • Less Blur: It can easily distinguish moving targets from their backgrounds. Images with moving targets present no image blurring and ghosting. Motion detection accuracy is increased by 200%, while motion blur is decreased by 80%.
  • Long Visible Distance: Its long visible distance enables a longer detection distance. It reduces light pollution at night and eliminates insects and dust reflections.
  • Image Distortion Corrections: It has a system-level omnidirectional distortion correction technology that fixes any distorted edge of the image, thus restoring the real and accurate image of the scene.
  • Clear Vehicle Plate Number: WizColor presents a more distinct image of the vehicle’s number plate (without exposure) and provides clearer details of the targets in the monitored scene.

Dahua’s WizColor technology

Overall, Dahua’s WizColor technology further enhances image quality even under low light conditions, effectively providing clearer and more vivid details of the targets in the monitored scene. 

With its significantly higher image brightness and lower image noise, WizColor is ideal for a wide range of application scenarios such as factories, farms, parking lots, fish ponds, courtyards, and more.
