 Why the movies are being digitized?

Digitization:

Digitization is the representation of an object, image, sound, document or a signal in the discrete form.
The resulting discrete form is called digital representation.
For easy understanding, digitizing means converting analog signal into digital signal.
Here we are going to see the digitization of image and movie only.

How digitization is done?

Let us take an image for illustration.
The first image is the analog image and the second one is the digital image.
Digitization of image involves several steps and the steps are as follows:

Step1: Any one box shouldn't be half filled. Fill the entire box with color.
Step2: One box should contain only one color.

If an image is represented like this then the image is called as digitized image.
The same steps are followed for digitizing the movie.

Need for digitization:

It gives longer life for our valuable images, videos, etc.,
It increases the quality of the images also.
The exact value of any image at any particular position can be predicted easily.

Note: The above mentioned concept for digitizing the image is just the simple and basic understanding of digitization. Actually the image processing is the wide area and it is the very small part in it.
