Image Processing Apparatus and Sheet

摘要

An image processing apparatus includes a processor and a memory storing instructions which, when executed by the processor, cause the image processing apparatus to perform: receiving target image data representing a target image; determining, from a plurality of pixels in the target image, a plurality of first-type pixels having a color value within a specific range having a color value indicating a color of a conversion target; calculating, for each of the plurality of first-type pixels, non-uniformity of color values of a plurality of pixels in a specific surrounding area including the first-type pixels; determining, from the plurality of first-type pixels, a second-type pixel which non-uniformity is a reference value or less, and converting a color value of the second-type pixel into a specific color value.

1. An image processing apparatus comprising:
a processor; and a memory storing instructions, the instructions, when executed by the processor, causing the image processing apparatus to perform: receiving target image data representing a target image, which is a processing target of image processing; determining, from a plurality of pixels in the target image, a plurality of first-type pixels having a color value within a specific range, the specific range having a color value that indicates a color of a conversion target; calculating, for each of the plurality of first-type pixels, non-uniformity of color values of a plurality of pixels in a specific surrounding area that includes the first-type pixels; determining, from the plurality of first-type pixels, a second-type pixel of which the non-uniformity is a reference value or less, and converting a color value of the second-type pixel into a specific color value.
