4k Camera

4k is a marketing term that stands for 4,000 pixels. It refers to the number of pixels on the horizontal axis of a high-definition video display.
The term 4k is often used in the context of television sets, digital cameras and computer monitors. It can also refer to video formats with a horizontal resolution of approximately 4000 pixels.
4K TVs are used as displays in many homes because they offer higher definition than normal 1080p TVs. They have four times as many pixels as 1080p which allows them to display an image with greater detail and clarity than their 1080p counterparts.
