Huawei’s reintroduction of the 40MP smartphone camera was a surprisingly impressive revelation back with the Huawei P20 Pro. The company improved on the formula’s low-light performance in the Huawei P30 Pro, setting a new bar for high-res mobile photography. Now there’s a new champion of the pixel count in town – the 64MP Realme XT. These two smartphone cameras are in many ways quite different, with different sensor sizes, lenses, and image post-processing. They’re also clearly aimed at very different price points. However, there are some key similarities based on prevailing mobile photography trends. Both phones achieve their seemingly huge megapixel count through the use of “quad Bayer” filters and a technology called pixel binning (or Tetracell, if you ask Samsung). In a nutshell, pixel binning takes a lower resolution sensor, slices each pixel into four, and uses a re-mosaic algorithm to construct a higher resolution image. The level of detail isn’t as good as a traditional Bayer-filter camera and the smaller pixel sizes can reduce light capture, resulting in more noise. However, these sensors claim to take good pictures in low-light by combing light from these four pixels b...
