History:

Using a mosaic PHOTODETECTOR, Eugene F. Sole from the Jet Propulsion Laboratory show how the first images can be produced in the digital domain. Engineer at Eastman Kodak, Steve Sasson, used solid state CCD chips to build a prototype digital camera with a resolution of 0.01 Megapixels, and recorded in black and white images to digital tape recorder. With this prototype model, Steve take the first picture in December 1975 with 23 seconds to capture.

In 1988, Fuji DS-1P became the first digital camera images in the database. However, the camera does not have to enter the market. In 1991, Kodak DCS-100 was the first commercially available digital cameras, which use a 1.3-megapixel sensor. With the progress of modern technology, a digital camera has become a multifunction and is able to capture the audio / video and photos.

Resources:

Digital camera consume more energy, which is included with the strong, a smaller battery. Batteries are widely divided into two groups, namely, ownership and ready. Ready is like AA batteries, CR2, CR-V3, AAA, and RCR-V3. They are Lithium-ion (Li-Ion) or nickel metal hydride (NiMH). Standard or non-rechargeable alkaline AA batteries do not work or work only for a short time in most of the camera.

Owner battery built as per the manufacturer `s custom specifications and are usually only available after the coin. In general, Lithium Ion battery used as the property of the battery for digital cameras.
