HD, Ultra High HD, what next? Are we running out of superlatives as we try to name the increase in our movie’s Video resolution? And are we even beginning to match the resolution of our eyes?
Those of us who remember the 1990’s and 2000’s will recall that for seeing home videos, DVD was the big thing, with the best resolution possible. DVD shows an image with 720X480.
As I write this article in 2013, 4k is the new big thing in display tech, and it’s coming to a big screen living room TV near you.
Today’s 1920 x 1080 resolution Full HD TVs present us with an image of around 2 megapixels, but this new generation of screens delivers an 8 megapixel image from hi-res cameras.
With new Ultra HD 4K TVs arriving this year from the big TV brands, it will soon become a format for both broadcast TV and Blu-ray.
What is 4K?
Technically speaking, 4K denotes a very specific display resolution of 4096 x 2160. This is the resolution of all 4K recordings, though many people use 4K to refer to any display resolution that has roughly 4000 horizontal pixels.
Ultra HD TVs have a resolution slightly lower than that – 3840 x 2160. That’s exactly four times higher than the full HD resolution of 1920 x 1080.
Many current movie cameras already film above 4K resolutions, for example the RED Epic which can film at a 5K resolution of 5120 x 2700 and the Sony F65 which films at 8192 x 4320 (8K).
This camera costs over Rs 11 Lakhs in Indian Rupees for recording 4 K videos, not counting the recurring costs.
High definition comes in two flavours: 720p (HD ready) and 1080p (Full HD), both of which offer more picture information than the standard definition formats. The more pixels that make up an image, the more detail you see – and the smoother the appearance of curved and diagonal lines. Ultra HD just takes that on to the next level.
A high pixel count also enables images to go larger before they break up, which suits the trend to bigger TVs. Ultra HD is already making big inroads into the world of digital cinema; almost all major Hollywood movies and TV shows are filmed in 4K – or even 5K.
What is Super Hi-Vision?
There’s another spanner in the works in the shape of Super Hi-Vision, an 8K format created by Japan’s national broadcaster NHK. It was trialled extensively at the London 2012 Olympics by the BBC, but doesn’t appear to have much chance of becoming a bona fide format just yet. It’s certainly one to watch; at double the frame rate of HD (at 120fps) and with a 7680 x 4320 pixel resolution (that’s around 32 megapixels), Super Hi-Vision demos have featured stunning 22.2 surround sound, too, thanks to twin subwoofers each the size of a small car.
Technically Super Hi-Vision also comes under the umbrella of the Ultra HD specification, which could store-up problems for future; how will anyone be able to explain the difference? Super-Ultra HD, anyone? Mega HD?
So you need very expensive cameras to capture these so called Ultra High def videos and images, and you need the proper display to see these Ultra High definition 4 K videos.
Now let us switch to Human Biology:
If the human eye was a digital camera, how many megapixels would it have?
The answer: 576 megapixels.
Most current digital cameras have 5-20 megapixels, and the latest ‘Ultra High Definition’ goes upto 32 Megapixels.
We are still a long long way from matching our incredible human eye’s resolution. Of course the eye has many other differences from manmade cameras. That will be another topic altogether. For now let us concentrate on resolution.
How did the human eye get such an impressive resolution?
As I looked at the net, I was quite taken aback to see some sites that claimed that all this super high resolution machinery of the human eye just ‘evolved’.
To me the human eye looks plainly to be a highly intelligent design! Who designed our eye?
Surely not random chance, as Evolutionists blindly believe? Could it be a mystical ‘Force’? Or possibly a Committee or pantheon of ‘gods’?
I mean, either one has to be extremely dumb or willfully self-deceiving to even think that our latest 4K cameras could just have evolved from the earlier generation of cameras.
Evolution theory is one of the greatest hoaxes shoved down the throats of our innocent kids in school under the garb of ‘science’ when it is not really science, and that too while these children are too young to even question it. .
The designer, at least to my mind, has to be one very intelligent personal being.
Who could even think of designing and bringing into existence our wonderful eye?
There is one who has claimed responsibility for designing my eye and yours.
The one who made my eye and yours says this: Your eye is a lamp, lighting up your whole body. If you live wide-eyed in wonder and belief, your body fills up with light. If you live squinty-eyed in greed and distrust, your body is a dank cellar.
Keep your eyes open, your lamp burning, so you don’t get musty and murky.
