Abstract
An array of light-emitting elements is switched on and off to produce a graded-intensity image on a photosensitive medium. Each light-emitting element is controlled by M-bit data representing the intensity of one image pixel, where M is a fixed integer greater than one. M strobe signals are generated for non-overlapping time intervals of different lengths, to strobe the M data bits for each light-emitting element. When strobed, each data bit switches its corresponding light-emitting element on or off. Image intensity depends on the total amount of time for which each light-emitting element is switched on.
