ABSTRACT:
An electronic imaging system includes a linear LED array for recording on a photosensitive medium an image defined by electronic signal information in binary word format by simultaneously controlling the energization of all the LED's at a constant energy level in a series of intervals, each of which is timed differently to correspond to a different one of the data bits in the binary words which comprise the image defining electronic signal information. Each LED is energized during each interval as a direct function of the state of the data bit corresponding to that interval for that LED.
