Abstract
An electronic camera which focuses images of an object on the image plane by means of suitable lenses such as those employed in 35mm cameras. The optical system is held stationary while a self-scanning linear array, comprised of a row of light-sensitive devices, is moved a measured distance in the image plane. The linear array is continuously clocked as it is moved along the image plane. The resulting video signal output is a train of pulses, each proportional in magnitude to the light intensity falling on the corresponding light-sensitive device. An internal line-filament light source moves in synchronism with the linear array so that only the image slice being viewed by the array at any instant of time as it traverses the image field is being illuminated. The light source is directed onto the object plane through a beam splitter so that the light shines through the optical axis of the lens for maximum efficiency.
