  • We can't resist cracking open the massive 108 MP wide-angle camera after we pull it free—Samsung hasn't been shy about this sensor's capabilities.

  • The sensor covers over double the surface area of the iPhone 11 Pro's 12 MP primary sensor, shown here for comparison.

  • Bigger sensors and more pixels don't always mean better images, though! 108 million pixels crammed into a 9.5 mm x 7.3 mm rectangle makes for some very tiny pixels, and that tends to produce noisy images in low-light conditions.

  • Samsung claims that this new sensor is able to shoot clear photos even in low light conditions thanks to a new barrier built around each pixel, plus a 3x3 pixel binning method they're calling "nona-binning" (3x3=9, hence the nona).

  • Pixel binning is a fancy term for combining groups of pixels to gather more light. The result is a brighter—though lower-resolution—photo that hopefully has less noise.

  • Binning isn't your average, everyday downsampling. All of this pixel partying happens at the hardware level, eliminating conversion errors.

在拆下了巨大的 108 MP 广角镜头后我们忍不住打开了它——Samsung 没有对这个传感器的能力有所隐瞒。

这颗传感器覆盖了超过两倍 iPhone 11 Pro12 MP 主传感器的面积,在这里可以看到对比。

虽然更大的传感器和更多的像素不总是意味着更好的画面!一亿零八百万像素塞进一个 9.5 mm x 7.3 mm 的矩形导致了这些非常小的像素,这会在弱光环境下产生噪点

Samsung 声称这颗新传感器可以在弱光环境下拍出清晰的照片,多亏了在每个像素周围设置的全新栅栏,加上 3x3 像素聚合模式它们称为“nona-binning”(3x3=nine,所以是nona)

像素聚合是一个奇妙的术语,组合像素来获取更多的光线。结果就是一张更亮但是分辨率更低的照片,以期来减少噪点。

聚合不是你平均每天的降采样。所有的这些像素组合发生在硬件层面,消除了转化错误。
