Comparison between Human Eye and Camera.?

Their function is essentially the same.  Like cameras, eyes have a lens that helps focus the image and a receptor of the image, called film in cameras, we have a retina filled with nerve endings that detect light sends it over to our brain to get interpreted.

I'm gonna go with C.  if only because, as a young lad, I noticed that the image is clearest when your eye is the same distance from the lens as the object you are viewing.\n\nthen I discovered if you take it out in the sun, you can burn a hole in a piece of paper.  boys may be dumb, but we sure do have fun at things!

http://clarkvision.com/imagedetail/eye-resolution.html\n\n324 megapixels\n\nThe 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. \n\nBased 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 \n90 degrees * 60 arc-minutes/degree * 1/0.3 * 90 * 60 * 1/0.3 = 324,000,000 pixels (324 megapixels).\nAt 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\n120 * 120 * 60 * 60 / (0.3 * 0.3) = 576 megapixels.\nThe full angle of human vision would require even more megapixels. This kind of image detail requires A large format camera to record.

This is so true, as a photographer I feel you are a genious to notice what society is blind to, black and white pictures show lots of emotion and focus the point of the picture better.  Great question.

Olympus is much better. In terms of upgradeability, service and durability. For vets, I recommend the CX31 or 41. You can have a phase contrast attachment for live cell microscopy. Also, you can opt to have a trinocular tube which can be connected to camera.\n\np.s. what country do you live in? i can recommend an olympus dealer.

Human eyes can be fooled by frame rate greater than or equal to 24. Resolution is irrelevant.

Different photoreceptors respond more or less strongly to different wavelengths (colours) of light. Digital cameras use more than one type of photodector for each pixel of the picture. By comparing the strengths of the signals from different detectors you can tell what colour the pixel should be.\n\nFilm cameras do the same thing, but use different chemicals in the film instead of photodectors. The different chemicals respond to different wavelengths of light.

That is how strong the picture or how many colrs and pixels are yoused

Many different ways.  Camera obscura.  High density filters.  Extremely fast exposures, etc.

u can use both to accessorize. (contact lenses,hip digital cameras)\nthey can both be used to capture memories.\novertime a persons eyes can become worn out, a camera could break down and not provide clearity.

The light gathering power and resolution are determined by the size of the objective lens, but not of its focal length. The ease of going to higher powers is determined by focal length.

It's called simultaneous viewing.  You actually look through the distance, near, and intermediate portions of the lens at the same time (they're each determined by a different curve on the lens).  Your brain automatically selects the clearest image.

they both have eyes...

Nearsighted people can't see things that are far away.\nFarsighted people can't see things that are near.\nKind of confusing, but there you go.

they are cheap compare to electron microscope.\nbut there is limitation of zooming large.

Which one is not one of these disadvantages??\n\nI'm voting for a - you could use a CCD and computer with a prism.
