Abstract

An image processing apparatus includes a job execution unit configured to execute at least one of an input job accompanied by inputting of image data and an output job unaccompanied by inputting of image data, an image data storage unit configured to store image data in a predetermined memory, a reference information storage unit configured to store reference information to the image data stored in the memory in the same memory, and a control unit configured to control the image data storage unit to newly store image data in the memory when the job executed by the job execution unit is an input job, and the reference information storage unit to store the reference information to the image data stored in the memory without newly storing image data in the memory when the job executed by the job execution unit is an output job.

Claims

1. An image processing apparatus comprising:

a job execution unit configured to execute at least one of an input job accompanied by inputting of image data and an output job unaccompanied by inputting of image data;

an image data storage unit configured to store image data input by execution of a job in a predetermined memory separately from the execution of the input job in conjunction with the execution of the job by the job execution unit;

a reference information storage unit configured to store reference information to the image data stored in the memory in the same memory separately from the execution of the job in conjunction with the execution of the job by the job execution unit; and

a control unit configured to control the image data storage unit to newly store image data input by the execution of the input job in the memory when the job executed by the job execution unit is an input job, and the reference information storage unit to store the reference information of the image data stored in the memory without newly storing image data handled by an output job in the memory by the image data storage unit when the job executed by the job execution unit is an output job.

2. The image processing apparatus according to claim 1, further comprising a history information storage unit configured to store history information generated in conjunction with the execution of the job by the job execution unit in the memory.

3. The image processing apparatus according to claim 1, wherein, when the job execution unit executes an output job to output synthesized image data generated by synthesizing a plurality of image data, the reference information storage unit stores reference information of the plurality of image data stored in the memory in the storage unit, while the image data storage unit does not store the synthesized image data in the memory.

4. The image processing apparatus according to claim 1, wherein, when the job execution unit executes an output job to output each of a plurality of divided image data obtained by dividing the image data, the reference information storage unit stores the reference information of the image data stored in the memory in the same memory, while the image data storage unit does not store the plurality of divided image data in the memory.

5. The image processing apparatus according to claim 1, wherein the reference information storage unit stores the reference information of the image data stored in the memory by each page.

6. The image processing apparatus according to claim 1, wherein the reference information storage unit stores the reference information of the image data stored in the memory by each document.

7. The image processing apparatus according to claim 1, wherein the image data storage unit processes the image data to store the same in the memory.

8. The image processing apparatus according to claim 1, wherein the memory is the other device connected through a network.

9. The image processing apparatus according to claim 8, wherein the reference information storage unit stores the reference information in a second memory different from the memory.

10. A method of controlling an image processing apparatus, comprising:

a job execution step of executing at least one of an input job accompanied by inputting of image data and an output job unaccompanied by inputting of image data;

an image data storage step of storing image data input by execution of a job in a predetermined memory separately from the execution of the input job in conjunction with the execution of the job by the job execution step;

a reference information storage step of storing reference information to the image data stored in the memory in the same memory separately from the execution of the job in conjunction with the execution of the job by the job execution step; and

a control step of controlling the image data storage step to newly store image data input by the execution of the input job in the memory when the job executed by the job execution step is an input job, and the reference information storage step to store the reference information of the image data stored in the memory without newly storing image data handled by an output job in the memory by the image data storage step when the job executed by the job execution step is an output job.

11. A program for executing the image processing method of claim 10 in an image processing apparatus.

12. A computer readable storage medium storing the program of claim 11.
