If you're wondering about the flash mechanism, it works just like a flashlight. There is a little lightbulb which gets power from the camera battery to light up when taking a picture with flash.
If you're wondering about the display, it works in the same way above only with LEDs (Light Emitting Diodes).
Who invented color photography and when?
James Clerk Maxwell, Scottish scientist, came up with the theory of color photography in 1855. He said that if you took three photos of the same scene, one each through a red filter, a green filter and a blue filter, put the photos into three different projectors, and fitted the projectors with the same filters used to take the photos in the first place, you would get a color picture. He actually tried it. It didn't work all that well because photo emulsions in Maxwell's day were orthochromatic, or only sensitive to one color, namely blue. But he got a picture that was in color, and that's pretty cool.
In 1903, the Lumiere brothers introduced the Autochrome process. These guys dyed potato starch red-orange, green, and blue-violet, waited until it dried, mixed the three colors and applied it to a glass plate. They then put a black-and-white photo emulsion over the top of it. They started making it on film in the 1930s, and it remained available until the 1950s.
In the 1930s, the Germans invented "Agfacolor Neu" film, which was like the films we can get today, and the American inventors Leopold Godowski and Leopold Mannes (who were professional musicians as well as trained scientists) invented Kodachrome also in the 1930s.
A 3 in 1 card reader is one device that can read 3 different card formats. These devices usually read cards like SD, microSD and others usually used in devices like cameras, phones and other similar devices. You would use the card reader to read and write data to these cards. For example, you could use a card reader to retrieve pictures from your digital camera's card to transfer them to your computer.

How do you open front camera nokia e71?
The Nokia e5 does not have a front camera. What you see is actually a light sensor.
The light sensor detects the light in the environment to determine how bright or dim to make the screen when using your phone.

How does thickness of convex lens affect focal length?
The focal length of a lens depends on
1. The refractive index of the material
2. Radii of the curvature of the two faces.
The lens maker's formula is
1/f = (mu --1) (1/R1 --1/R2)
mu- the refractive index of the material with which lens is made
R1 and R2 are the radii of curvature of the faces.
f- the focal length of the lens thus formed.
your question needs clear information. As the thickness of the lens of same diameter is increased then radii of curvature would decrease, hence focal length would decrease. But as the diameter gets increased then there comes a chance of maintaining the radii of curvature to be the same. If so, then no change in the focal length. But, if diameter is not increased to the right extent then we cannot be sure about the variation of focal length.
What are dome cameras known for?
a dome security camera is a camera that you hang from the ceiling, or on a wall, and the camera itself is protected by a dome shaped housing.

How many digital cameras sold in the UK?
It is hard to get precise numbers, but 60 million would be a good working figure.
How do you improve picture quality?
In most cases, you're out of luck. I've had many reasons to do this myself and with not much luck. The only true way of increasing the resolution of a picture is to do it with optical technology where they use a powerful camera lens to produce a higher resolution of the original but even that will depend on the quality of the original. In forensics they also have sophisticated software that can accomplish this but again, it's out of reach of everyday people.
Sorry :S

When and who invented cameras?
The first camera would have been the camera obscura. The camera obscura has been known to scholars since the time of Mozi (around 480 BCE) and Aristotle (around 350 BCE). A camera obscura is a room or a box with a hole in one side through which light passes, causing an inverted image to be projected onto the a wall of the room or back of the box.
In 1039 AD an Arabian scholar, Alhazen, wrote the first clear description and analysis of the device. In 1550 a lens was fitted to into the hole of a camera obscura. Over the years following various items were added such as a diaphragm to sharpen up the image and a mirror was added to make the images upright. Starting in about 1676 a portable camera was available. It was in the 1800s that the first practical camera came about. in 1826 Frenchman Nicephore Niepce used a camera obscura for Photography for the first time. 1856 saw the first camera that took small images of live subjects. George Eastman, an American, produced the first box 'brownie' hand held camera bought by the general public.
Another answer
It was only in 1855 that you could get a photo taken and printed properly, but this doesn't mean that you could not take a photograph earlier. In 1817 a gentleman inventor named Nicéphore Niépce made a small and primitive camera from which he succeeded in taking a partial photo of low quality. This was the birth of the camera as we know it.
Cameras were actually developed over time rather than having been invented by just one person. Nicephore Niepce used what is known as a bitumen to create the first actual photograph in 1825. The first portable camera was built by Louis Daguerre in 1837. The first camera that was practical for everyday use was invented by George Eastman in 1888.
