It’s truly a reference to very early camera know-how. In the Nineteen Thirties, video cameras used glass vacuum tubes that transmitted electrons down the size of the tube to the photosensitive sensor.
The outer diameter of those tubes grew in sizer from ½ inch to ⅔ inch and lastly 1 inch, however the precise photosensitive sensor was at all times a lot smaller – often round two-thirds of the diameter of the tube. However, since the tubes have been technically a part of the image-sensing know-how, producers might market them as 1-inch sensors.
So why are telephone camera sensors being known as 1-inch sensors? It basically comes all the way down to the dimension of the sensor, which is the similar dimension as the sensor that might’ve related to a 1-inch vacuum tube (a minimal of 9 x 12mm) in an early video camera.
