Abstract
Certain examples described herein relate to an optical controller (140) for an exposure unit (115, 215) of a printer. In certain examples, memory (150) stores a plurality of data structures each comprising adjustment factors useable to adjust a plurality of optical elements (216) of the exposure unit. Different data structures correspond to different gray coverages in an image generated by the printer. In certain examples, a processor (160) determines gray levels for different image regions in input image data. In certain cases, the processor links the determined gray levels to corresponding data structures within the plurality of data structures to obtain adjustment factors for the different image regions. In certain cases, the processor adjusts the optical elements for each image region using the corresponding obtained adjustment factors to enable the generation of an exposed image using the exposure unit based on the input image data.
