Abstract
According to one embodiment, an image processing device capable of removing a horizontal streak that may show when a document is scanned and made into a file is provided. An image processing device according to one embodiment includes: an image processing unit configured to generate smoothing image data obtained by applying smoothing to image data, and save, as an image file, non-smoothing image data in which smoothing is not applied to the image data when a difference between the non-smoothing image data and the smoothing image data is equal to or greater than a threshold value, and the smoothing image data when the difference is smaller than the threshold value; and a storage unit configured to save the image file.
Claims20
An image processing device, comprising:
- an image processing component configured to save image data as a non-PDF image file which is not in PDF format and a PDF image file which is in PDF format, and enable a user access to the non-PDF image file when a difference between an image obtained by rasterizing the non-PDF image file and an image obtained by rasterizing the PDF image file is equal to or greater than a threshold value, and to the PDF image file when the difference between an image obtained by rasterizing the non-PDF image file and an image obtained by rasterizing the PDF image file is smaller than the threshold value;
- and
- a storage component configured to save the non-PDF image file and the PDF image file.
A method of preventing or reducing horizontal streaks in a scanning operation, comprising:
- saving image data as a non-PDF image file which is not in PDF format and a PDF image file which is in PDF format;
- enabling a user access to the non-PDF image file when a difference between an image obtained by rasterizing the non-PDF image file and an image obtained by rasterizing the PDF image file is equal to or greater than a threshold value, and to the PDF image file when the difference between an image obtained by rasterizing the non-PDF image file and an image obtained by rasterizing the PDF image file is smaller than the threshold value;
- and
- saving the non-PDF image file and the PDF image file.
A multifunction peripheral, comprising:
- a scanner;
- a printer;
- an image processing component configured to save image data as a non-PDF image file which is not in PDF format and a PDF image file which is in PDF format, and enable a user access to the non-PDF image file when a difference between an image obtained by rasterizing the non-PDF image file and an image obtained by rasterizing the PDF image file is equal to or greater than a threshold value, and to the PDF image file when the difference between an image obtained by rasterizing the non-PDF image file and an image obtained by rasterizing the PDF image file is smaller than the threshold value;
- and
- a storage component configured to save the non-PDF image file and the PDF image file.
