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.
Claims20
An image forming apparatus comprising:
- an image forming unit configured to form an image on a sheet, the image being formed based on a target image;
- an image reading unit configured to read a sheet face on which the image is formed and generate a scan image based on the read sheet face;
- an image inspecting unit configured to compare the scan image with the target image to detect an error in the scan image;
- and
- a generating unit configured to generate a modified image by:
- (i) converting the scan image to one of Portable Document Format (PDF), Hypertext Markup Language (HTML), and Office Open eXtensible Markup Language (OOXML);
- and (ii) when the image inspecting unit detects the error, embedding error information regarding the detected error in the scan image as a layer different from a layer of the scan image.
A method comprising:
- forming an image on a sheet based on a target image;
- reading a sheet face on which the image is formed and generating a scan image based on the read sheet face;
- comparing the scan image with the target image to detect an error in the scan image;
- converting the scan image to one of Portable Document Format (PDF), Hypertext Markup Language (HTML), and Office Open eXtensible Markup Language (OOXML);
- and
- when the error is detected, embedding error information regarding the detected error in the scan image as a layer different from a layer of the scan image to generate a modified image.
An image forming apparatus comprising:
- an image forming unit configured to form an image on a sheet, the image being formed based on a target image;
- an image reading unit configured to read a sheet face on which the image is formed and generate a scan image based on the read sheet face;
- an image inspecting unit configured to compare the scan image with the target image to detect an error in the scan image;
- and
- a generating unit configured to generate a modified image by:
- (i) converting the scan image to one of Portable Document Format (PDF), Hypertext Markup Language (HTML), and Office Open eXtensible Markup Language (OOXML);
- and (ii) when the image inspecting unit detects the error, digitally embedding error information regarding the detected error in the scan image.
