How Digital Cameras Work?
The basic working of the Digital camera and Film camera is one and the same. Both use the shutter, lens and aperture. The Lens captures the light and then it passes it into the aperture, which controls the light and the shutter opens and closes to control the duration of light, which enters.
The major difference is the technology of capturing the image. Digital camera does not use film to store the image. In digital camera an image sensor is used to capture the image. It is a computer silicon chip. On the surface of this chip there are millions of pixels, which are photosensitive diodes.
The shutter button of the digital camera activates a metering cell, which manages the shutter speed and aperture according to the amount of light coming through the lens. When a person clicks on the camera shutter each and every pixel of the image sensor stores the intensity of the light, which falls on it by gathering an electrical charge. When strong light hits a pixel, it generates high charge and weak light generates low charge.
After the shutter closes charges from every pixel is converted into digital numbers. This series of numbers creates an image on a computer screen.

Customer Review: A true timesaver!

Duracell Mobile Charger With 2AA And 2AAA Pre Charged Rechargeable Nimh Batteries, CEF23DX4N
Duracell Mobile Charger With 2AA And 2AAA Pre Charged Rechargeable Nimh Batteries, CEF23DX4N
Customer Review: Versatile battery-charger with dual-personality
The Duracell Mobile Charger (CEF23) is an extremely versatile charger. It actually has two operating modes, as selected by the MODE button:
1. As an AA/AAA NiMH battery charger, or
2. As an USB charger for USB-powered devices.
In battery-charger mode, the unit is a smart charger that accepts 1-4 AA/AAA cells in any combinations. The charger can be powered by either 100-240V universal AC input, or 12V DC input. This means you can also operate it from your vehicle's cigarette lighter adapter. Note that the car adapter is included in the CEF23DX4N, but not in the CEF23DX2.
The charging current is 550mA for each cell. So it takes about 4 hours to full charge up the included 2100mAh low-self-discharge cells (which are the Duracell-equivalent of Sanyo eneloop). I consider this a good compromise between shorter charging time and longer battery lifespan.
One really nice feature of this charger is that it has four individual battery status indicator lights. The status light for each cell turns RED when charging, GREEN when the cell is fully charged. It will even blink if you accidentally inserted an alkaline cell.
In USB charger mode, the unit generates a regulated 5-volt supply at its USB socket. You can then connect an USB-powered device (such as IPOD charger) to this unit. Input power for this USB charger can be from one of the following sources:
1. From 100-240V universal AC input,
2. From 12V DC input (car adapter), or
3. From four AA/AAA NiMH cells in the battery compartment.
The third way is the most interesting, because in case of emergency, you can even use 4 alkaline cells to power this USB charger, in order to charge up your cell phone's battery.
I must say that this charger is really well designed. It is a great bargain even if all you need is a simple battery charger. The USB charger mode is just an extra bonus.
