Abstract
An edge amount detector detects an edge amount from RGB signals, and a filter processor synthesizes an output for edge enhancement with an output for smoothing at a proportion based on the detected edge amount. Another edge amount detector detects an edge amount of a black component from CMY signals, and an ink generator/undercolor remover changes an ink generation rate according to the detected edge amount.
