Stellar Galaxy S23 Ultra HP2 sensor optimizations could elevate Samsung nightography to new levels

Ice universe has been dropping Galaxy S23 Ultra-shaped leaks again, with focus appropriately being made on the camera equipment this time. It has long been rumored that the upcoming Samsung Galaxy S23 Ultra would feature an ISOCELL HP2 200 MP sensor as part of its camera equipment, and the tipster claims that “significant” optimizations will ensure that the S23 Ultra’s night photography may even beat out the Galaxy S22 Ultra with its specialized night mode and “nightography” cameras.

The leaker specifically states that night photography has been “significantly improved” for the Samsung Galaxy S23 Ultra while also sharing a post from the Chinese social media site Weibo that apparently explains why future owners will be shooting for the moon with less noise than ever. The explanation, in both Chinese and English, is difficult to decipher for the general observer, thanks to the presence of multiple camera-related initialisms (see embedded tweet below).

It seems FWC (Full Well Capacity) will be less aggressive to 10,000e- ("e-" = electrons), which apparently should help determine how pixels respond with light especially after dark. The source also states “RMS, RTN, FPN are significantly optimized”, with those who are in the know (pdf) understanding that those stand for Root Mean Square, Random Telegraph Noise (can cause flickering pixels), and Fixed-Pattern Noise (occurs in long exposure photography), respectively. Basically, the combination of noise reduction and control is the name of the game here, especially during low-light photography.

Ice universe essentially says the same, opining that “night scene performance can be better” for the Samsung Galaxy S23 Ultra thanks to the presence of the ISOCELL HP2 sensor (purportedly acting more like a unit produced by rival company Sony) and the above-mentioned optimizations for dealing with noise and noise sources. Samsung has previously heralded the night-mode capability of many of its devices, from the A32 to the Note10 and right up to the Galaxy S22 Ultra, with the latter phone sporting a nightography camera system headed by a 108 MP sensor (Samsung ISOCELL HM3), and now the Galaxy S23 Ultra is also looking especially promising in this particular field.
