Reading through the spec for my new camera phone I came across a couple of terms I'd never encountered before, such as "Pixel Binning" so, obviously, I Googled them and these are the results, which I thought might interest others too.
PIXEL BINNING
Pixel binning is a technique used in digital photography to improve image quality by combining adjacent pixels into larger "superpixels". This increases the light sensitivity of each superpixel, which can help to reduce noise in low-light conditions.

Mine, apparently, has 16-in-one pixel binning which means that its 200MP sensor will combine 16 pixels into one large pixel and both will deliver a 12MP picture. The negative aspect of pixel binning is that you have a lower-resolution image. So while there is less noise in your image, there's also probably less detail.
7P
It also has a 7p lens, so what is a 7P lens (or a 6p lens, or a 5p lens etc)? Simply put it means that my phone has an array of 7 plastic lenses. 7p. Geddit?
Theoretically it also means that picture quality is better the higher you can pee. I think 8p is currently the highest in a "normal" camera phone, the Xiaomi 12T Pro for instance, which retails at around £750.00. while 5p or 6p is standard, but that will rapidly change I'm sure. Of course, the quality of the lenses probably has far more bearing on picture quality than how many you've got. The poorer the lens(es) the greater the aberration, etc.
Some people (wrongly) say that more pee can bring more light, but how can you bring more light when you've just put an extra lens in front of your sensor? The correct term is not "more light" but, "better light", since the lens element is there to filter out/correct flaws. An example would be how an "achromatic" or "apochromatic" lens is used to minimise the colour fringe effect (caused by lens dispersion) - but if you actually feel the need to get all technical about it, you can read this: en.m.wikipedia.org/wiki/Chromatic_aberration
Super QPD, OIS, and EIS
Super QPD
Super QPD uses a single lens over four adjacent pixels to detect the phase differences in both horizontal and vertical directions andblah-blah-blah... Yeah. It speeds up autofocusing.
OIS (optical image stabilization)
It stabilizes the photography process by calculating the phone's movement and moving the lens, to achieve optical compensation with a gyroscope. Among all image stabilization technologies, it delivers the best image effect in most cases.
EIS (electronic image stabilization)
EIS skips on physical hardware and attempts to do the same as OIS using software tricks. The process uses your phone's accelerometer to detect hand movements and align each frame. Since the camera lens or sensor doesn't move with EIS, capturing each frame is quicker.
So, there you go, clear as mud.
