Especially in connection with "digital cinematography" and "digital cinema", we often hear of cameras, projectors, and the like being capable of handing "2k" or "4k" images.
These terms simply mean that the width of the image format is in the general area of 2048 px or 4096 px, respectively. The corresponding height is of course a function of the aspect ratio involved.
The notation is based on the widespread, but unattractive, convention in which the prefix "kilo", abbreviated "k", is used to mean a multiple of 1024. It is often used in connection with bits or bytes, essentially never for hertz, volts, or sheep, and sometimes for pixels.
Of course the standard prefix for a multiplier of 1024 is "Kibi", abbreviated "Ki".
Thus we can say that image formats in the "4k" family have a width in the general vicinity of 4 Kipx.
Best regards,
Doug
