IMAGE PROCESSING DEVICE GENERATING BINARY IMAGE DATA BY SELECTING SPECIFIC COMPONENT
First Claim
1. An image processing device comprising:
- a processor configured to perform;
acquiring target image data representing a target image including a letter, the target image data including a plurality of component image data corresponding respectively to a plurality of components constituting a color coordinate system; and
generating binary image data representing the letter in the target image by using the target image data, the generating of the binary image data comprising;
identifying a background color value representing color of background of the target image, the background color value being composed of values for the plurality of components;
identifying a letter color value representing color of the letter in the target image, the letter color value being composed of values for the plurality of components;
acquiring a difference between the background color value and the letter color value, the difference including a plurality of component differences corresponding respectively to the plurality of components;
selecting, from among the plurality of component image data, one specific component image data corresponding to a specific component from among the plurality of components, the specific component corresponding to a maximum component difference among the plurality of component differences; and
performing a binarizing process on the selected one specific component image data to generate one binary image data.

Abstract
An image processing device includes a processor configured to perform: acquiring target image data representing a target image; and generating binary image data representing the letter in the target image by using the target image data. The generating of the binary image data comprises: identifying a background color value representing color of background of the target image; identifying a letter color value representing color of the letter in the target image; acquiring a difference between the background color value and the letter color value, the difference including a plurality of component differences; selecting one specific component image data corresponding to a specific component from among the plurality of components, the specific component corresponding to a maximum component difference among the plurality of component differences; and performing a binarizing process on the selected one specific component image data to generate one binary image data.
