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, when printing is to be performed in a first mode by the printing executing section, first image-processing on original image data to generate first processed image data; perform, when printing is to be performed in a second mode by the printing executing section, second image-processing on the original image data to generate second processed image data, wherein the second mode is different from the first mode, and the second image-processing is different from the first image-processing; supply the first processed image data to the printing executing section when the first processed image data is generated; and supply the second processed image data to the printing executing section when the second processed image data is generated, wherein, to perform the first image-processing, the controller is configured to: calculate an index value relating an edge-intensity about a target pixel in object image data; correct, when the target pixel is a first type of pixel, the value of the target pixel so that the print-density of the target pixel to be printed in the first mode is higher than that of the target pixel to be printed in the second mode, the first type pixel representing that the index value of the target pixel indicates the edge-intensity of the target pixel being relatively high; and correct, when the target pixel is a second type of pixel, the value of the target pixel so that the print-density of the target pixel to be printed in the first mode is lower than that of the target pixel to be printed in the second mode, the second type pixel representing that the index value of the target pixel indicates the edge-intensity of the target pixel being relatively low.
