Digital image processing is the use of a digital computer to process digital images through an algorithm. As a subcategory or field of digital signal processing, digital image processing has many advantages over analog image processing.

The input of a DIP system system is a digital image and the system process that image using efficient algorithms, and gives an image as an output. The most common example is GIMP or Adobe Photoshop.
