What is 4K Camera?
Whether you’re talking televisions, videogames, YouTube videos or cameras, 4K is a pretty big deal. But what does 4K actually mean, and what difference does it make to you and your camera?
To explain, let’s go back to the days before the HDTV revolution. These old screens could display an image with a resolution of 858 x 480 pixels. This was known as 480p, or “SD” for “standard resolution”.
Then came so-called “HD-ready” displays, which could display images at 720 x 1280 pixels. This “720p” format became known as “HD”.
Then we had true high definition screens that could display at 1920 x 1080 pixels, which we know as “1080p” or “Full HD”. (In all cases the resolutions could be "i" instead of "p", such as 1080i, depending on whether the display was interlaced or progressive scan… but that's another conversation!)
This brings us to 4K, which can display images as 3860 x 2160 pixels. However, instead of continuing the convention and calling it “2160p”, after the vertical pixel count, a clever marketing department began calling it “4K” or “Ultra HD”. This is because it contains roughly four times as many pixels as 1080p / Full HD resolution.
