Today, technological breakthroughs have made it possible for us to convert analogue information ( obtained from a fluctuating wave) into digital information that can be possible with computer-readable digits, like 1 or 0, which can also be referred to as bits. This basic improvement clearly defines how visual and audio information can be handled more efficiently. The digital camera is one of the most improved technological device which clearly surpasses its predecessor in output and performance! Unlike the conventional type that works using chemical and mechanical processes, digital cameras work with in-built computer devices and images are recorded electronically. Due to the drastic improvements in digital imaging, digital cameras have gained much recognition. Therefore, it is important to understand what goes on within these amazing devices. But first, the major components.

The components of a digital camera include a series of lenses that focus light so that the image of a scene is produced. Rather than focusing the light on a film like the conventional cameras, a digital camera focuses light on a semiconductor device that has been made to record light electronically. There is the in-built computer that helps to break down the electronic information into a computer-readabledigital forms. These components give the fun to the way the digital camera works! Let us now see how the digital camera achieves thepurpose for which it was meant.

Some digital cameras have a sensor, instead of a film, with which it
converts light into electrical energy. This is similar to the
semiconductor earlier referred to above. You can have different types
of sensors though, the basic function remains that they turn light
into electricity and help the digital camera to read the value of
accumulated charge of each cell in the image.

The camera captures images in different amounts of details called
resolution, which is measured in pixels. The more pixels a camera has,
the larger the pictures and the more details the camera can capture.
The pictures do not have to be blurry or grainy within the appreciable
pixel. For example, with a 1600 by 1200 mega pixel, one can print a 4
by 5 inch print at this resolution, and of similar quality obtainable
from a photo lab. Now, that you know why a good resolution is
important, you may want to ask: “but how does the digital camera add
colour to the image”? Simple, just read on and get the gist below.
