ABSTRACT:
An apparatus and method are provided for recording images on photon sensitive recording media (20) which includes a source (12) of image pixel data in digital form having a multiplicity of possible intensity values, a photon generator 16 for exposing the photon sensitive recording media at a fixed intensity level, and a controller (24, 22, 14) for controlling the amount of time of exposure of the recording media in correspondence with the pixel data intensity values from the source. Previously known apparatus either have problems producing clearly distinguishable shades of gray on the recording media or else require much more expensive technology. The most likely applications are the production of hard copy from medical imaging data where clarity and detail are the most important consideration. Other applications may prove feasible with any form of digitizable image data.
