Qualcomm wants to keep a step ahead of the competition in the field of smart cards for smartphones, and since the manufacturers rely more and more on photo and video performance, the founder had mentioned the capacity of his Snapdragon 865 to manage recording 8K videos.
The founder has recently published a video called "Professional quality 8K video captured by a Snapdragon 865-powered smartphone", a demonstration video of the 8K captured from a terminal with its Snapdragon 865 and using a sensor photo Sony IMX586 48 megapixel.
It was in Arizona that Qualcomm took the shots. If the brand insists on 8K it is because it is particularly resource-hungry. It is therefore necessary to have a gigantic computing capacity to capture the photos, analyze them, encode them and store them in the device. As such, UFS 3.0 storage will undoubtedly have to impose itself as a standard on the photophones of tomorrow to meet these speed needs.
Unfortunately for Qualcomm, the video delivered is certainly attractive for the magnificent scenes it offers, but turns out to be unflattering for the Snapdragon 865.
So, whether you choose to watch video in 8k, 4k or Full HD, you notice an enormous amount of digital noise in the image. The limits of the 48-megapixel sensor to photosites whose size is very small do not allow you to fully enjoy the show. Unable to capture enough light, the sensor compensates by increasing its sensitivity and thus generates the noise that appears clearly on the screen.
The situation is all the more penalizing for Qualcomm that the brand is not an expert in image processing, and that the images are thus delivered in their "raw" aspect. Manufacturers more comfortable in the discipline such as Sony, Samsung or Huawei should succeed in offering image processing to reduce noise and fully exploit the 8K.
