4K Definition :
Since the commercial launch of 4K camera in the late part of 2012, it has created a great buzz in the multimedia world. The 4K cameras are very rapidly catching the eyes of professional photographer or general camera lover. People also know it as Ultra High Definition. Now question arises, what is 4K or 4K camera? Generally a SD camera can give you picture of 720*480 pixels, on the other hand HD camera can provide 1920*1080 pixels. But 4K can offer you 3840 pixels (horizontal)*2160 pixels (vertical) and the horizontal can go above 4000 pixels, almost 2 times wider and 2 times higher than its HD camera, accordingly giving an aggregate screen determination that is somewhat over 4 times larger than the HD camera, thus it is called 4K. in simplest terms if you compare HD resolution be vertical pixel height (720p,1080p) then 4K can also be called 2160p. At this moment, the most widely known type of UHD is the 4K resolution.
