Abstract
An image processing device includes an image reader that reads an image, a first determiner that determines whether character crushing occurs when the image is binarized, a second determiner that determines a rate of a photographic region in the image, and a controller that performs conversion into monochrome N-gradation image data based on determination results of the first and second determiners.
Claims11
An image processing device comprising:
- an image reader that reads an image;
- a first determiner that determines whether character crushing occurs when the image is binarized;
- a second determiner that determines a rate of a photographic region in the image;
- and
- a controller that performs conversion into monochrome N-gradation image data based on determination results of the first and second determiners.
2 more elements
A control method comprising:
- reading an image;
- determining whether character crushing occurs when the image is binarized;
- determining a rate of a photographic region in the image;
- and
- performing conversion into monochrome N-gradation image data based on determination results of the determinations.
2 more elements
A non-transitory computer readable recording medium recording a program that causes a computer to execute:
- reading an image;
- determining whether character crushing occurs when the image is binarized;
- determining a rate of a photographic region in the image;
- and
- performing conversion into monochrome N-gradation image data based on determination results of the determinations.
