发明名称 Resolution conversion via intensity controlled overscanned illumination for optical printers and the like having high gamma photosensitive recording media
摘要 A method for resolution conversion by microaddressing an image transition in a printer includes steps of writing a print bit at zero intensity when a current image bit is in a second state and a displacement distance is greater than or equal to one-half of a pitch distance; writing the print bit at maximum intensity when the current bit is in a first state and the displacement distance is greater than or equal to one-half of the pitch distance; and writing the print bit at less than maximum intensity when the current image bit is in the first state and the displacement distance is less than one-half of the pitch distance, the step of writing the bit bit at less than maximum intensity including a step of intensity modulating a writing device based on a function proportional to a sum of the displacement distance plus one-half of the pitch distance. A print intensity controller to generate intensity data includes a modulo counter for generating print bit position data based on an image raster width and a number of intensity steps; and a memory for producing the intensity data based on the number of intensity steps, the print bit position data, a current image bit and an adjacent image bit.
