A process for selecting output levels for multi-level halftones in the presence of an unstable display device.

摘要

A process for selecting output levels for multi-level halftones optimizes the stability of an output device, even though the system contains unstable components. First, a function which quantifies undesirable mean level image artifacts for the unstable display device is defined, to stabilize the tone transfer curve of the unstable device. Then density levels are chosen to minimize the function and optimize stability of the output device. <IMAGE>
