History:

Using a mosaic photosensor, Eugene F. Lally of the Jet Propulsion Laboratory first showed how still photos could be a digital domain produces. An engineer at Eastman Kodak's Steve Sasson, used solid state CCD chips to build a prototype digital camera with a resolution of 0.01Megapixel digital and recorded in black and white images on a magnetic tape. With this prototype, Steve has captured the first image in December 1975, less than 23 seconds for it.

In 1988, Fuji DS-1P was the first digital camera, the recordings as a computer file. But the camera is never in the U.S. market. In 1991 DCS-100 Kodak was the first commercially available digital camera that uses a 1.3-megapixelSensor. Development of technologies, digital cameras have become the modern multi-functional and are now able to capture audio / video and photos.

Power:

Digital cameras consume a lot of energy, the battery is supplied by powerful, small in size. Batteries can be divided broadly into two groups, namely off-the-shelf and proprietary. Off-the-shelf batteries are like AA, CR2, CR-V3, AAA, and RCR-V3. They are lithium-ion (Li-Ion) or nickel-metal hydride (NiMH). Standard AA non-rechargeable alkaline batteries either do not work or work for a very short time in most cameras.

proprietary batteries according to the manufacturer's own specifications and installed are usually available as aftermarket replacement parts. In general, lithium ion batteries commonly used as proprietary batteriesDigital cameras.
