Peningkatan kualitas
Tinjauan historis Pengolahan Citra Digital
Industri surat kabar menggunakan sistem transmisi kabel Bartlane untuk mengirim gambar melalui kabel bawah laut antara London dan New York pada tahun 1920‐an.
Jumlah tingkat keabuan yang dikodekan sistem Bartlane bertambah dari 5 menjadi 15 tingkat pada akhir 1920‐an.

Lahirnya of Komputer Digital Citra‐citra tadi sudah digital; tetapi TIDAK dapat dianggap sebagai hasil pengolahan citra digital. Jad , apa itu Jadi, apa tu Pengolahan e go a a ccitra t ad digital (Digital g ta ( igital Image Processing‐DIP)? • Pengolahan citra digital menggunakan komputer digital
DIP bergantung pada perkembangan komputer digital dan teknologi pendukung lainnya (mis. penyimpan data (storage), display dan transmisi)
