Image processing apparatus

摘要

An image processing apparatus causes a printing executing section to perform a printing process using color-materials, the image processing apparatus includes: a first processing unit that performs a first image-processing by processing original image data in order to generate first processed image data; and a supplying unit, wherein the first processing unit includes: a calculating unit that calculates an index value relating an edge-intensity about a target pixel in object image data; and a correcting unit that corrects a value of the target pixel based on the index value of the edge-intensity, wherein the correcting unit corrects the value of the target pixel such that print-density of the target pixel increase if the target pixel is a first pixel, and wherein the correcting unit corrects the value of the target pixel such that print-density of the target pixel decrease if the target pixel is a second pixel.

1. An image processing apparatus configured to cause a printing executing section to perform a printing process using color-materials, comprising:
a controller configured to:
perform first image-processing by processing original image data in order to generate first processed image data; andsupply the first processed image data to the printing executing section in response to the first processed image data being generated, wherein performing the first image-processing comprises:
calculating an index value relating an edge-intensity about a target pixel in object image data;correcting a value of the target pixel such that print-density of the target pixel increases in response to the target pixel being a first type of pixel, the first type pixel representing that the index value of the target pixel indicates the edge-intensity of the target pixel being relatively high; andcorrecting the value of the target pixel such that print-density of the target pixel decreases in response to the target pixel being a second type of pixel, the second type pixel representing that the index value of the target pixel indicates the edge-intensity of the target pixel being relatively low, and wherein, in response to the target pixel being the first type of pixel, as the index value of the target pixel indicates the edge-intensity of the target pixel being higher, the controller is configured to correct the value of the target pixel so that the print-density of the target pixel becomes higher.
