Abstract

In accordance with an embodiment, a printing apparatus comprises a data acquisition section configured to acquire printing data; an image determination section configured to determine a character part or a picture part of an image indicated by the printing data; an image process section configured to erase the picture part or the part other than the character part from the image indicated by the printing data; and a printing control section configured to execute a printing of an image processed by the image process section.

First claim

What is claimed is:

1. A printing apparatus, comprising:
a data acquisition section configured to acquire printing data;
an image determination section configured to determine a character part or a picture part of an image indicated by the printing data;
an image process section configured to erase the picture part or the part other than the character part from the image indicated by the printing data, and then determines a pixel of which a density value is lower than a pre-set density value in the image for which erasing has been executed, and then replaces a pixel value of the determined pixel with 0 or a value that indicates white; and
a printing control section configured to execute a printing of an image processed by the image process section.

2. The printing apparatus according to claim 1 , wherein
the image determination section determines the character part of the image indicated by the printing data; and
the image process section erases the part other than the character part from the image indicated by the printing data.

3. The printing apparatus according to claim 2 , wherein
the printing control section executes, in a case where the character part in the image is found by the image determination section, a printing of the image processed by the image process section; and executes, in a case where the character part in the image isn't found by the image determination section, no printing of the image in which the character part isn't found.

4. The printing apparatus according to claim 1 , wherein
the image determination section determines the picture part of the image indicated by the printing data; and
the image process section erases the picture part from the image indicated by the printing data.

5. The printing apparatus according to claim 1 , further comprising:
an output control section configured to output a processed image processed by the image process section before the printing control section executes a printing of an image, wherein
the printing control section executes, in a case where a printing execution command is acquired from the user after the output control section output the processed image, a printing of the processed image; and executes, in a case where a printing stop command is acquired from the user after the output control section output the processed image, no printing of the processed image.

6. An image processing apparatus, comprising:
a data acquisition section configured to acquire image data;
an image determination section configured to determine a character part or a picture part of an image indicated by the image data;
an image process section configured to erase the picture part or the part other than the character part from the image indicated by the image data, and then determines a pixel of which a density value is lower than a pre-set density value in the image for which erasing has been executed, and then replaces a pixel value of the determined pixel with 0 or a value that indicates white; and
an output control section configured to output an image processed by the image process section.
