ABSTRACT:
A filtering processing unit of an image processor includes a component extraction unit, a character edge quantity calculation unit, and a correction unit corresponding to each of a plurality of frequency bands and direction components, and an adder. The component extraction unit extracts signals from a corresponding one of the frequency bands and direction components. The character edge quantity calculation unit calculates a character edge quantity from an output of a corresponding one of the component extraction units. The correction unit performs correction control to the output of a corresponding one of the component extraction units based on a character edge quantity calculated by a corresponding one of the character edge quantity calculation units. The adder adds outputs of all the correction units.
