The term "4K" is generic and refers to any resolution with a horizontal pixel count of approximately 4,000. [4]: 2 Several different 4K resolutions have been standardized by various organizations. The terms "4K" and "Ultra HD" are used more widely in marketing than "2160p".
Image resolution is the level of detail of an image. The term applies to digital images, film images, and other types of images. "Higher resolution" means more image detail. Image resolution can be measured in various ways. Resolution quantifies how close lines can be to each other and still be visibly resolved. Resolution units can be tied to ...
The resolution 3840 × 2160, sometimes referred to as 4K UHD or 4K × 2K, has a 16:9 aspect ratio and 8,294,400 pixels. It is double the size of Full HD ( 1920 × 1080 ) in both dimensions for a total of four times as many pixels, and triple the size of HD ( 1280 × 720 ) in both dimensions for a total of nine times as many pixels.

(* The pixel number of 6,000x4,000 ist the number of "effective pixels". The sensor usually has a few extra rows of pixels on all four sides, which explains the sensor resolution of 24.3 MPixels often stated, but no information about the exact image size available.) 6,016 4,000 24,064,000 24.1 Nikon D3300 Canon M50: 6,048 4,032 24,385,536 24.4
The online dictionary explains that “4k” number “Refers to 4,000 pixel resolution, a very high resolution for video and digital photography that results in clear images.”
This "inch" system gives a result approximately 1.5 times the length of the diagonal of the sensor. This "optical format" measure goes back to the way image sizes of video cameras used until the late 1980s were expressed, referring to the outside diameter of the glass envelope of the video camera tube.
The numerical value of a lens aperture. The ratio of the focal length of the lens divided by its effective aperture diameter. [4] FF: Full frame, where the image sensor is approximately the same size as a 35 mm film: 36 × 24 mm. FP: Focal plane.
