Abstract
An image forming apparatus includes an image forming unit, an image reading unit, an image inspecting unit and a history generating unit. The image forming unit forms an image on a sheet. The image reading unit reads a sheet face on which the image is formed, thereby generating a scan image. The image inspecting unit compares the generated scan image with a normal image to detect an error in the scan image. When the image inspecting unit detects the error, the history generating unit generates detection information on the detected error and embeds the generated detection information in the scan image, thereby generating a history image.
Claims15
An image forming apparatus comprising:
- an image forming unit configured to form a reproduced image on a sheet;
- an image reading unit configured to read a sheet face on which the reproduced image is formed and generate a scan image based on the read sheet face;
- an image inspecting unit configured to compare the generated scan image with a normal image comprising an original image from which the reproduced image is formed to detect an error in the scan image;
- and
- a history generating unit configured to convert the scan image file format to one of Portable Document Format (PDF), Hypertext Markup Language (HTML), and Office Open eXtensible Markup Language (OOXML), the history generating unit being further configured to, when the image inspecting unit detects the error, generate an error name text and embed the generated error name text in the scan image after the scan image has been converted to the PDF, HTML, or OOXML, thereby generating a history image,
- wherein the error name text is text that identifies the error in the scan image.
A history generating method comprising:
- forming a reproduced image on a sheet;
- reading a sheet face on which the reproduced image is formed and generating a scan image based on the read sheet face;
- comparing the generated scan image with a normal image comprising an original image from which the reproduced image is formed to detect an error in the scan image;
- converting the scan image file format to one of:
- Portable Document Format (PDF), Hypertext Markup Language (HTML), and Office Open eXtensible Markup Language (OOXML);
- and
- when detecting the error, generating an error name text and embedding the generated error name text in the scan image as a layer different from a layer of the scan image after the scan image has been converted to the PDF, HTML or OOXML, thereby generating a history image, wherein the error name text is text that identifies the error in the scan image.
An image forming apparatus comprising:
- an image forming unit configured to form a reproduced image on a sheet;
- an image reading unit configured to read a sheet face on which the reproduced image is formed and generate a scan image based on the read sheet face;
- an image inspecting unit configured to compare the generated scan image with a normal image comprising an original image from which the reproduced image is formed to detect an error in the scan image;
- and
- a history generating unit configured to convert the scan image file format to a structured language file format which adds meta-information by tags, the history generating unit being further configured to, when the image inspecting unit detects the error, generate an error name text and embed the generated error name text in the scan image after the scan image has been converted to the structured language file format, thereby generating a history image,
- wherein the error name text is text that identifies the error in the scan image.
