Since most image-processing operations, such as sharpening up a fuzzy document, or altering the colours in a photograph, involve looking at the value of a particular pixel and then altering it depending on the value of adjacent pixels, this is a real advantage.

ECONOMIST: Analogue computing

Applications of image processing include such popular consumer features as light balancing and face recognition, now standard on most digital cameras, which can also be associated with voice recognition.

CNN: The story

The transition to digital image processing and storage has brought mighty companies such as Kodak to their knees and spawned a great many consumer electronic companies that have created image capture and display devices with features and capabilities that would never have been possible with analog technology.
