A digital camera, digital camera or in short, is a camera that takes digital photos and video with an electronic image sensor. Digital cameras capable of performing various functions such as displaying images once the photo is taken, the storage of hundreds and thousands of pictures and video recording. Just like a camera, digicam also operates using a lens with an aperture to focus the light. The cameras are mostly used in mobile phones to vehicles. Usually camerasare portable, simple and easy to use.

5 and major basic terms associated with digital camera are:

1) Mega pixels
2) Focal length
3) Digital zoom
4) ISO
5) shutter lag

1.Mega pixels:
The word "pixel" is a combination of images and Element (Pix - Picture; El-Element). It is defined as the smallest element of an image, and is a measure of the Resolution. 1,000,000 pixels equal mega pixels. The more pixels, the higher the resolution will be. Thenumber of pixels is related to the quality of camera and image quality. The camera with 7.6 mega pixels will be used for larger images and have better quality. The resolving power is measured by mega pixels. The number of mega pixels camera required depends on the nature and size of the print image. For example, if a camera varies from 4 mega pixels, then we can take pictures of 4 million pixels. The camera with 3mega pixels and is above the image suitable for printing.

2.Focal Length:
The focal length is a measure of how it converges or diverges light as the lens of a camera image enlarges. It is classified into two namely wide angle and tele. While taking photo, we see that the vision that looks far seen through the naked eye. Wide-angle lens are used for the dramatic landscape as the light of day, shooting mode, night mode, white balance, etc. is a telephoto lens that takesdistant objects much closer. It is used for shooting sports and wildlife sanctuaries.

3.Digital Zoom
The digital zoom is used to improve the display of an image that brings the subject closer. The only drawback is the digital zoom reduces image quality. The optical zoom brings the subject closer to you by adjusting the camera lens. It produces an image better than digital zoom. Digital zoom enlarges the pixels in electronic form at the center of the photo. Thisto disable the digital zoom feature to get a good quality picture.

4.ISO:
ISO stands for International Standards Organization. This organization provides some measures to take a picture and this certification is given to the camera is more sensitive to light. A lower ISO number (100 or below) is less sensitive to light and is most suitable lighting conditions. A higher ISO number is very sensitive to light and dark is rightconditions and used to take indoor photos without flash.

Lag 5.Shutter:
shutter lag is the time between pressing the camera button to take a picture and when the image is actually recorded. Since the shutter lag is extended, the photos get missed and not end up in a photo you want what we expected. This may not be a factor in interesting and important, but many manufacturers do not list the shutter lag time. So the best way to know the shutter lag istaking a photo before a camera is purchased.

So before you buy a camera to take advantage of all these 5 important features for better quality, cost effective, portable Thus digicam and take a good decision and buy a digital camera.
