In 1969 the Apollo 11 astronauts landed on the moon, the Woodstock Festival attracted nearly 500,000 concert-goers, and George Smith and Willard Boyle invented the first Charge Coupled Device (CCD). Although greeted with less fanfare than the other events of 1969, the CCD gave rise to digital imaging. By replacing the traditional film with an electronic CCD sensor, digital imaging revolutionized photography ranging from the Hubble telescope in outer-space to the cell phone in your pocket. This entry describes the capture, storage and manipulation of digital images.
