Así que 64 megapíxeles, uhmmm 16*4=64 y ahí estám los 64 megapíxeles xD
https://www.gsmarena.com/redmi_note_8_p ... -39307.php"The phone has four rear cameras. A 64 MP primary sensor uses a quad bayer filter to capture 16 MP photos with 1.6μm equivalent pixel size. There's also an 8 MP ultra-wide angle shooter with a 120-degree field-of-view, a 2 MP macro camera and a 2 MP depth sensor to aid in creating bokeh for portrait mode shots. On the front there's a 20 MP selfie snapper."

https://en.wikipedia.org/wiki/Samsung_CMOS"ISOCELL Plus: ISOCELL Plus replaces ISOCELL's metal grid barriers with an innovative new material developed by Fujifilm. This minimizes optical loss and light reflection, providing higher color fidelity and up to a 15% enhancement in light sensitivity compared to ISOCELL"
https://www.samsung.com/semiconductor/i ... e-sensors/Tetracell also known as Quad Bayer or 4-cell. Features a repeating 4×4 pattern with 4 red, 8 green and 4 blue pixels. For darker scenes, signal processing can combine data from each 2x2 group, essentially like a larger pixel. For brighter scenes, signal processing can convert the Tetracell into a conventional RGB filter to achieve 4x higher resolution. Resolution & pixel size listed below is after re-mosaic signal processing.
https://en.wikipedia.org/wiki/Bayer_filter#Quad_Bayer"Sony introduced Quad Bayer color filter array, which first featured in the Huawei P20 Pro released on March 27, 2018. Quad Bayer is similar to Bayer filter, however adjacent 2x2 pixels are the same color, the 4x4 pattern features 4x blue, 4x red, and 8x green. For darker scenes, signal processing can combine data from each 2x2 group, essentially like a larger pixel. For brighter scenes, signal processing can convert the Quad Bayer into a conventional Bayer filter to achieve higher resolution.[16] The pixels in Quad Bayer can be operated in long-time integration and short-time integration to achieve single shot HDR, reducing blending issues. Quad Bayer is also known as Tetracell by Samsung and 4-cell by OmniVision.
On March 26, 2019, the Huawei P30 seres were announced featuring RYYB Quad Bayer, with the 4x4 pattern featuring 4x blue, 4x red, and 8x yellow."

It features 43.7 megapixel (7,968×5,480) resolution and the industry-first 0.7μm-sized pixels. The new sensor effectively outputs 10.9-megapixel images and is built in mind for slim full display devices allowing Samsung to expand the display size on future handsets without compromising image quality."
