Charge Coupled Devices

Ever since the birth of digital imaging, sales in digital cameras have boomed. This is partly due to the fact that digital cameras allow you to save money on film as well as developing since you don’t have to pay for either. Another factor that has enabled digital cameras to edge out their competition (film cameras) is that it allows a great deal of room for error. In most cases, digital cameras also have much better resolution than their film counterparts.

A lot of digital camera owners know their camera’s pixel rating but very few photography enthusiasts are aware of their camera’s charge coupled device otherwise known as CCD. A charge coupled device allows your camera to see and remember an image. It does this by converting light into a electrical charge. Each shade of color is assigned a specific electrical charge that can digitally be interpreted back into an image and stored. The utilization of a charge coupled device in digital cameras has led to a great improvement in picture resolution. A charge coupled device is used in both digital photographic and video cameras.

The efficiency of a charge coupled device exerts a great influence in the quality of the picture or video you take. An excellent charge coupled device is able to take in a lot of light, process it quickly, and process it well. These factors are often influenced by the size of the charge coupled device because a bigger surface area means it can absorb more light. Hence, the larger the charge coupled device of your camera, the better the image.

The problem with this is that consumers want smaller cameras with better quality images. The camera manufacturers get a good compromise by using a half-inch charge coupled device in non-professional digital cameras. The charge coupled device that other hand held cameras use are even smaller at only one-sixth to one-third of an inch. They’ll have a sleeker-looking camera, but poorer images.

Professional cameras use not just one but three charge coupled devices. They have one for each of the three primary colors red, yellow, and blue. With three charge coupled devices processing each color independently, the resulting image is brighter, more vivid, and clearer. Because of the number of charge coupled devices that a professional camera uses, they tend to be bigger and more expensive than those for everyday use.

Charge coupled devices may also be rated according to the number of pixels it uses. The higher it is, the better the resulting image. Having a camera with a remarkably high pixel rating is only necessary if you’re planning to enlarge your pictures. For the most part, a clearer image will only make the pictures you take more ‘noisy’ as it may pick up even the bit of dust on the camera’s lens. If you don’t really plan on making photography your hobby and you just want to take snapshots of memorable moments, you can settle for some of the more standard digital cameras available on the market today.
