Abstract:
A non-impact recording apparatus comprising:a plurality of recording elements;a source of first data signals representing for each of plural pixels at a predetermined pixel bit depth, a density, size or percentage of coverage for recording each of the pixels;a first look-up table memory that stores multibit gamma adjustment data pertinent to the predetermined pixel bit depth and is responsive to the first data signals for adjusting the density, size or percentage coverage of each of the pixels with a gamma adjustment related to development by the apparatus and generating multibit gamma adjusted second data signals;a second look-up table memory for generating third signals related to uniformity correction of the recording elements;a process look-up table memory having as inputs thereto the gamma adjusted second data signals and the third signals and generating in response to the inputs fourth multibit signals relating to exposure on-times for recording pixels by the recording elements; anda control for loading multibit gamma adjustment data into said first look-up table memory, the control being operational with different predetermined pixel bit depth modes of the first data signals to load the first look-up table memory with gamma adjustment data corresponding to the pixel bit depth of the first data signals.
