DeepPRIME noise reduction

Cutting-edge technology

Would you like a new sensor in your camera? One that delivers finer detail and less noise? It sounds impossible, but this is effectively what DxO’s unique DeepPRIME and DeepPRIME XD — eXtra Detail — technology delivers. Here’s how it works.


Denoising and demosaicing explained

Two of the fundamental steps are demosaicing and denoising.
Demosaicing is the process of converting individual pixel values for red, green, and blue into accurate colors (learn morehere). Denoising is the correction of erroneous pixels generated by interference or heat inside your camera — something that becomes more pronounced when shooting at high ISO levels. These processes are critical in extracting the best possible quality from your RAW files.

DxO breaks new ground

Denoising affects demosaicing and vice versa, so there have to be compromises no matter the order in which they are performed — until now. DxO has always been at the forefront of developing this technology and in recent years artificial intelligence has led to new possibilities.

We already had countless photographs available to us as a result of calibrating cameras and lenses in our laboratory and so we were able to use these images again — literally billions of samples — to train a neural network to understand noise, color, and detail.

Pioneering artificial intelligence

Our neural network is smart enough to run demosaicing and denoising at the same time — a world first! This means that it has a deep understanding of how to eliminate noise and render accurate colors using both processes simultaneously, and therefore never prioritizing one over the other.

Incomparable results

DeepPRIME removes noise and recovers information without losing detail, creating more natural transitions and textures. The results are spectacular and, as explained below, the introduction of DeepPRIME XD has pushed the boundaries even further. Compared to conventional RAW conversion technologies, DeepPRIME delivers the equivalent of an extra two stops of ISO of detail; with DeepPRIME XD, it can be 2.5 stops, sometimes more.

Unbelievable results. Try DeepPRIME XD for eXtra Detail

There are two levels of DeepPRIME processing available in DxO PhotoLab 7. Both algorithms reduce noise, increase clarity, and purify results from your camera’s sensor, but DeepPRIME XD mode requires more intensive handling.

While our original DeepPRIME processing remains the best choice for images where some degree detail of extraction is desired, DeepPRIME XD delivers even finer detail in both high and low ISO images thanks to a more intricate algorithm. Expect photos free from noise, with smoother bokeh, finer textures, and more realistic and natural color.

This cutting-edge denoising tech is compatible with all major manufacturers’ cameras: Canon, DJI, Fujifilm (including cameras featuring X-Trans sensors), Hasselblad, Nikon, Panasonic, Pentax, Olympus/OM System, Sony, Leica, and more.
