Digital camera information about the astronauts' position. As with Texas Instruments employee Willis Adcock's filmless camera (US patent 4,057,830) in 1972, the technology had yet to catch up with the concept. The Cromemco Cyclops was an all-digital camera introduced as a commercial product in 1975. Its design was published as a hobbyist construction project in the February 1975 issue of "Popular Electronics" magazine, and it used a 32×32 Metal Oxide Semiconductor sensor. Steven Sasson, an engineer at Eastman Kodak, invented and built the first self-contained electronic camera that used a charge-coupled device image sensor in 1975. Early uses were mainly military and
Robot (camera) 24 × 24 mm image format, but many used 18 × 24 mm (half-frame) and 24 × 36 mm (standard Leica format), and non-standard formats such as 6 × 24 mm (Recorder 6), 12 × 24 mm (Recorder 12) and 16 × 16 mm (Robot SC). Around 1930 Heinz Kilfitt, a trained watchmaker, designed a new 35 mm film compact camera using a 24×24 mm frame format (instead of the Leica 24×36 mm or cine 18×24 mm formats). The 24×24mm square frame provided many advantages, including allowing over 50 exposures per standard roll of Leica film instead of 36. Kodak
