Working of a Digital Camera

In a digital camera a film is replaced by a digital chip. When light enters the camera, it strikes the digital sensors instead of a film in any other camera.

The digital sensor is made of millions of tiny sensor points. These points are called”pixels”. Hence mega pixels become millions of dots of light for each picture. The more the number of dots or say the more the mega pixels, the higher is the resolution. In simpler words, more mega pixels mean bigger and better pictures.

When the light reflected through the image strikes the sensor, these pixels get excited. The sensors convert the reflected light into electrical signals which are then passed through a digital converter. After passing through the digital converter these signals get converted into purely digital signals.

Then these are passed through a series of electronic filters which adjust the color and balance of the picture. Followed by this is a compression cycle for efficient storage which compresses the image to the smallest possible size by disposing the unnecessary pixels.

The quality of a digital camera is decided by its mega pixels and its storage capacity. The pictures clicked are first stored in the buffer memory of the camera. When this is full, pictures are to be transferred to the storage media or the memory card. The digital images clicked by this camera cam be easily transferred to internet or computer.
