Abstract
Official abstract text for this publication.
An output density range is divided such that, after gradation targets have been applied, adjusted density ranges for output are uniform across all objects. Furthermore, through reverse calculation using the gradation targets that are set in one-to-one correspondence with the objects, adjusted density ranges of the respective objects are set independently.
First claim
Opening claim text (preview).
What is claimed is: 1. An image processing apparatus that obtains output image data by processing input image data, comprising: a density adjustment level input unit capable of inputting an adjustment level for adjusting density in a designated output density range of a plurality of predetermined density ranges in the output image data; a density adjustment unit that adjusts density of the input image data according to the input adjustment level, a gradation conversion unit th…
