While conventional cameras rely on a dedicated image processor for converting captured Raw image data into JPEG image output, on most smartphone cameras this task is undertaken by the CPU. Chip maker Qualcomm, whose Snapdragon chipsets are in use by a large proportion of Android and Windows smartphones, has published a blog post to explain in some more detail how its processors can help boost low light image quality on mobile devices.

'First, a fast image signal processor (ISP) is key to making sure noise reduction is performed as quickly as possible. We’ve also introduced technologies such as wavelet noise reduction (WNR) and temporal noise reduction (TNR) to identify and clean up noisy areas in photos, using our state-of-the-art algorithms and fast ISP.'

In addition to these advanced noise reduction methods the Snapdragon processors also use local tone mapping to brighten specific image areas while maintaining detail and keeping noise under control. For additional information you can read the original article on the Qualcomm Blog
