Digital Camera Technology Revealed About The Basics of Digital Photography

Digital Cameras are all the rage these days. These latest technology cameras are getting popular with each passing day indeed. The entire world of photography and video shooting has taken a huge leap after the arrival of digital cameras in the market.

For a first time digital camera user it is essential to know their working as well as technology. If you want to enrich yourself with such important DigiCam technology, read this article.

First things first. Understand the terms digital camera and analog camera. The digital cameras are much like the simple analog camera. They contain some basic things like a lens, light shutter that are found in an analog camera as well. The difference lies in the technology. The fundamental difference in the technology is of the photo sensitive cells. In a conventional camera the light when reflected from the light shutters falls on the film. But in a digital camera, the light falls up on the image censors or the photo sensitive cells. These cells are many in numbers.

An image censor or the photo sensitive cell is actually a microchip of 10mm. This is the most prominent feature of the digital camera technology that distinguishes the digital camera from a formula analog camera. The image censors are responsible to convert the light signals in to the electrical signals.

In scientific terminology, each image sensor is a charged-couple device (CCD) made up of silicon. The silicon chip image censors are also capable of measuring the frequency of light falling on them. The sensors play a significant role in the development of digital signals. Once the light signals are stored by image censors as electrical signals, they are transferred to another device that converts these signals to digital mode.

The device that converts analog signals to digital signals is known as Analog to Digital Converter (ADC). The silicon chip consists of several electronically charges tubes containing both a positive and negative charge on them. These tubes are called photo sensitive diodes as they are light sensitive diodes which are also known as photosites. They convert the light charges (photons) into electrical signals called electrons. The sensors are very much sensitive. The more the light falls on the sensors, the more pixels they produce. Every 1000 array silicon chip produces 1 pixel.

Simply, you can explain the process in two sentences. The process of converting the light signals into the digital signals starts from the lens. The light enters into a digital camera through lens. Then the light falls up on the Charged Couple Devise (CCD) which produces the electrical charges.

After this the electrical charges are converted into the digital signals by the Analog to Digital Converter. Some digital camera manufacturers do not use the CCD. Instead they use the Complementary Metal Oxide Semiconductor (CMOD). This is much cheaper in price than the CCDs. Also the CMOD takes up less power than the other photosensitive devices. The technology for these chips is same as the CCD. It is also based on the microchip technology.

The Complementary Metal Oxide Semiconductor (CMOD) is generally used in the smaller cameras. Despite of the fact that they are light, cheap and also efficient, most of the mega pixel digital cameras use CCD technology. This is because the CMOD may be cheaper but you will get a much better picture quality by using the CCD.

The terms used and specific information related to the digital camera technology may sound a bit difficult for you initially. But you will find a number of resources that explain the process of working of a digital camera in detail. Also the camera experts publish their reviews and articles to teach the public about proper functioning of the digital camera to avoid any complications in their usage.

Even if you don’t want to read an expert’s review on the technology of DigiCams this article can surely help you know the digital camera working. The points discussed are simple, and yet too essential for a DigiCam buyer.
