No, they are not equivalent. The only thing they have in common is that they block the image. I didn't say 'block light' because quite a bit of light can pass through the eyelid if you are in a lit place, and that is normal. A shutter would be worthless if any light at all is let through the shutter itself. There is a little more similarity between eyelids and video cameras.
Eyelids keep the eyes lubricated and can help brush away very small particles of dust or debris, especially with the help of tears. Also, when the eyelids are closed, the brain instantly begins to relax a little, since a huge amount of information passes to the brain through virtually constant visual stimulation during the day.
Shutters are designed to keep ALL visible light away from the light sensitive surface until the photographer decides to capture an image- a static image in the case of single lens reflex or similar cameras. Then the shutter is opened for a (usually) very brief period, typically a small fraction of a second. Then when it closes it remains closed until the photographer is ready to capture another image.
The light sensitive part of the eye is not like the film or plate of a single lens reflex camera. The retina picks up and transmits continuous action and passes it directly to the brain. In other words, in life we see things as they happen in very close to 'real time'. The film or light sensitive plate in a single lens reflex camera is designed to capture a static image; all the light that hits the surface creates a single image, even if the surface is exposed for a considerable length of time. That is why a too slow shutter speed for shooting conditions produces a blurry image, and it is why 'double exposure' was a common problem when film was the standard medium.
In the case of video, the shutter remains open for as long as the continuous data from the light sensitive surface is sending data to memory, then it closes. When it closes it remains closed and no light enters until the videographer chooses to capture more action. So there is something in common between the eyelids and the shutter of a video camera, but they are still far from being equivalent.

Pinhole camera and human eye similarities?
I think a pinhole camera is similar to the human eye because like the pinhole camera when it sees something it reflects the image but it is an inverted image. With the human eye the brain corrects it and turns it the right way up. The pinhole cameras image is not corrected because it does not have a lens.

What is the advantages of the human eye over the camera?
The primary advantages are:Sensitivity range (we can see in much brighter and dimmer light situations)The processing done to the image by our brains
Why does a camera need a shutter when an eye does not?
A camera's shutter is similar to the human eyelid, so in a sense eyes do have 'shutters' Obviously :D
A bird that can imitate human and some animal sounds?

What are similarities and differences between a camera and a human eye?
The human eye can be compared to a photographic camera because the pupil of the eye and the shutter on a camera, is what controls the amount of light let in. As for differences, a human eye is alive while a camera is an inanimate object invented by man.
