Abstract
In accordance with an embodiment, in an image processing apparatus which includes an arithmetic element and executes an image processing on a first image data read by a scanner from a manuscript including a printing area, the arithmetic element acquires the first image data from the scanner, generates second image data by executing an image processing on the first image data, recognizes the printing area in the first image data based on the second image data, and cuts out an image in the printing area from the first image data as a third image data.
Claims16
A non-transitory storage medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:
- acquiring, by an arithmetic processor, a first image data read by a scanner from a manuscript containing a printing area;
- generating, by the arithmetic processor, second image data by executing an image processing on the first image data, wherein the second image data is generated by extracting a contour line from the first image data, painting the contour line as a function of a color space, and reducing a contrast of the first image data, wherein the contour line is determined based on respectively binarizing, in relation to a threshold value, a lightness component value and a saturation component value of the color space, wherein the color space comprises a hue component value, the saturation component value, and the lightness component value;
- recognizing, by the arithmetic processor, the printing area in the first image data based on the second image data;
- and
- facilitating cutting, by the arithmetic processor, an image in the printing area from the first image data as a third image data.
A device for correctly detecting a printing area, comprising:
- an arithmetic processor;
- and
- a memory that stores instructions that, when executed by the arithmetic processor, facilitates performance of operations, comprising:
- acquiring a first image data read by a scanner from a manuscript containing a printing area;
- generating second image data by executing an image processing on the first image data, wherein the second image data is generated by extracting a contour line from the first image data, painting the contour line as a function of a color space, and reducing a contrast of the first image data, wherein the contour line is determined based on respectively binarizing, in relation to a threshold value, a lightness component value and a saturation component value of the color space, wherein the color space comprises a hue component value, the saturation component value, and the lightness component value;
- recognizing the printing area in the first image data based on the second image data;
- and
- cutting an image in the printing area from the first image data as a third image data.
