What resolution is the world in ?

[Detection]

Might sound a weird crazy question that has come from the mouth of a drugged up hobo .... but a question all the same :D

Maybe the Question should be, how many megapixels does your eyesight have

A Full HD 1080p DSLR major-megapixel photo of an object vs the actual object sitting on the desk in-front of you, and the photo looks sharper and clearer ?

Is it my eyesight or is there a genuine explanation for it ?

Does the camera somehow manage to grab image/light data your eyes can not until it is shown on screen ?

How many megapixels equivalent does the eye have?

The eye is not a single frame snapshot camera. It is more like a video stream. The eye moves rapidly in small angular amounts and continually updates the image in one's brain to "paint" the detail. We also have two eyes, and our brains combine the signals to increase the resolution further. We also typically move our eyes around the scene to gather more information. Because of these factors, the eye plus brain assembles a higher resolution image than possible with the number of photoreceptors in the retina. So the megapixel equivalent numbers below refer to the spatial detail in an image that would be required to show what the human eye could see when you view a scene.

Based on the above data for the resolution of the human eye, let's try a "small" example first. Consider a view in front of you that is 90 degrees by 90 degrees, like looking through an open window at a scene. The number of pixels would be

90 degrees * 60 arc-minutes/degree * 1/0.3 * 90 * 60 * 1/0.3 = 324,000,000 pixels (324 megapixels).

At any one moment, you actually do not perceive that many pixels, but your eye moves around the scene to see all the detail you want. But the human eye really sees a larger field of view, close to 180 degrees. Let's be conservative and use 120 degrees for the field of view. Then we would see

120 * 120 * 60 * 60 / (0.3 * 0.3) = 576 megapixels.

The full angle of human vision would require even more megapixels. This kind of image detail requires A large format camera to record.

Interesting read.

I would guess it's because the photo is still, while your eyes/body are constantly moving (so it's impossible to "focus" on something as much as a still shot can "focus", but I don't know.

It's your mind playing tricks on you, mentally you assume the picture is crisper because it's a picture and it's supposed to be totally awesome because of the resolution and that other jazz.

DSLRs take in quite a bit more light per area of photosensitive surface. Additionally, they have proprietary image processing to convert the raw data from the sensor into something that looks very crisp to the human eye.

As humans, we have our own built-in image processing, but it's more geared toward practical purposes, like motion detection and depth perception.

wow, similar to mine, only I think mines got an extra 3 next to the 7 :D

Its.... retina.... resolution.

Apple had it right since the beginning.

[philcruicks]

Its over 9000!

But yeah I don't think you can ever really work it out as each eye is different and as stated you eye and brain stitch it all together seamlessly so you consciously don't notice.

Due to a recent upgrade I am now able to see in IMAX 3D. :p

I did too...but I never asked for this.

*sunglasses on*

YEAHHHHHH ADAM JENSEN!

Who has more megapixels?
