Abstract

An image processing apparatus includes a detection unit and a determination unit. The detection unit detects an error by comparing image data related to a print job with read image data obtained as a result of reading a print output related to the print job. The determination unit compares read image data related to a post-error print output, which is a continuously-printed print output related to the print job for a page subsequent to a page in which the error is detected, with the image data when the error is detected by the detection unit, so as to determine a process for recovering the print job by using the post-error print output.

Claims

1. An image processing apparatus comprising:

a detection unit that detects an error by comparing image data related to a print job with read image data obtained as a result of reading a print output related to the print job; and

a determination unit that compares read image data related to a post-error print output, which is a continuously-printed print output related to the print job for a page subsequent to a page in which the error is detected, with the image data when the error is detected by the detection unit, so as to determine a process for recovering the print job by using the post-error print output.

2. The image processing apparatus according to claim 1,

wherein the determination unit includes

a recovery determination unit that compares the read image data related to the post-error print output, which is the continuously-printed print output related to the print job for the page subsequent to the page in which the error is detected, with the image data when the error is detected by the detection unit, so as to determine whether or not the print job is recoverable by using the post-error print output, and

a recovery-image-data determination unit that determines recovery image data used for recovery in addition to the post-error print output if the recovery determination unit determines that the print job is recoverable, and

wherein the image processing apparatus further comprises:

a recovery execution unit that executes a recovery print job, which uses the recovery image data determined by the recovery-image-data determination unit, upon completion of a current print output.

3. The image processing apparatus according to claim 2, further comprising:

a print-job stop unit that stops the print job if the recovery determination unit determines that the print job is not recoverable.

4. The image processing apparatus according to claim 2,

wherein the recovery-image-data determination unit sets image data of the page subsequent to the page in which the error is detected as the recovery image data, and

wherein the recovery execution unit executes the recovery print job when stoppage of the print job is cancelled.

5. The image processing apparatus according to claim 1, further comprising:

an output unit that outputs information related to recovery of a print job.

6. The image processing apparatus according to claim 1,

wherein the detection unit detects the error by comparing a density histogram of the image data calculated for respective predetermined multiple regions with a density histogram of the read image data.

7. A non-transitory computer readable medium storing a program causing a computer to execute an image processing process, the image processing process comprising:

detecting an error by comparing image data related to a print job with read image data obtained as a result of reading a print output related to the print job; and

comparing read image data related to a post-error print output, which is a continuously-printed print output related to the print job for a page subsequent to a page in which the error is detected, with the image data when the error is detected, so as to determine a process for recovering the print job by using the post-error print output.

8. An image processing method comprising:

detecting an error by comparing image data related to a print job with read image data obtained as a result of reading a print output related to the print job; and

comparing read image data related to a post-error print output, which is a continuously-printed print output related to the print job for a page subsequent to a page in which the error is detected, with the image data when the error is detected, so as to determine a process for recovering the print job by using the post-error print output.
