Analog cameras require a diaphragm opening of the film and 1 / f seconds so that light can be captured by the film received into an image. In digital cameras, the film is not needed anymore as analog cameras. Digital cameras use a sensor known as CCD or CMOS.
In principle, there is no significant difference between digital cameras and analog cameras, because it contains the basic technology is just simple. An analog camera using celluloid film, has three basic elements, respectively, are elements of various kinds of optical lens, a chemical element seluloidnya own films, and the mechanical element is the camera body itself. Chemical elements in digital cameras nowadays become indispensable element of chips that can be CCD (Charge Coupled Device) or CMOS (Complementary Metal Oxide Semiconductor) which regulates the sensitivity of the lighting and the "digital film" in modern cameras today.
Both CCD sensor and CMOS chips actually began to develop at the same time, these two chips convert light into electrons to become digital images. The fundamental difference between them is the CCD generally produce high-quality images and low noise. While in the CMOS, noise generated on the digital image is usually more.
CMOS sensor generally uses less battery power, while the CCD due to the special process performed at the time taking pictures, taking power 100 times more than similar CMOS sensor. In addition, fabrication of the CMOS chip manufacturing is cheaper than CCD. However, along with the development of the two sensors when it appears to start is at a comparable stage and compete very tight.
