when was the the sensor invented
Since the mid-1970s, Kodak has invented several solid-state image sensors that converted light to digital pictures for professional and home consumer use. In 1986, Kodak scientists invented the world's first megapixel sensor, capable of recording 1.4 million pixels that could produce a 5x7-inch digital photo-quality print. In 1987, Kodak released seven products for recording, storing, manipulating, transmitting and printing electronic still video images.
