Image processing apparatus

An image processing apparatus configured to cause a printing executing section to perform a printing process using a color-material, comprising:

• a controller configured to:
• perform a first image-processing by processing original image data in order to generate first processed image data;
• and
• supply the first processed image data to the printing executing section in response to the first processed image data being generated,
• wherein the performing of the first image-processing comprises:
• detecting a boundary between a first region and a second region, wherein the first region and the second region are included in an object image represented by object image data to be processed, wherein the first region and the second region are adjacent to each other, wherein a value of a first pixel group included in the first region is different from a value of a second pixel group included in the second region, and wherein the print-density indicated by the first pixel group belonging to the first region is lower than the print-density indicated by the second pixel group belonging to the second region;
• and
• correcting the value of the first pixel group included in the first region, and
• wherein the correcting of the value of the first pixel group comprises:
• correcting values of first adjacent pixels, which are a part of the first pixel group and located adjacent to the second region, such that the print-density of the first adjacent pixels increase;
• and
• correcting values of first not-adjacent pixels, which are a part of the first pixel group and located apart from the second region, such that the print-density of the first not-adjacent pixels decrease.

A non-transitory computer-readable medium storing computer-readable instructions that, when executed by a controller of an image processing apparatus that is configured to cause a printing executing section to perform process using color-materials, instruct the controller to execute processes comprising:

• performing a first image-processing by processing original image data to generate first processed image data;
• and
• supplying the first processed image data to the printing executing section in response to the first processed image data being generated,
• wherein the performing of 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;
• and
• correcting 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 and, as the index value of the target pixel indicates the edge-intensity of the target pixel being higher, the instructions instruct the controller to correct the value of the target pixel so that the print-density of the target pixel becomes higher.
