Abstract

An image processing apparatus comprising, a detector unit configured to detect an event that a user logged in to the image processing apparatus logs out, an query unit configured to be operable when said detector unit detects the event, to query the user whether or not to change a setting of a job under execution, and a control unit configured to be operable when the setting of the job is to be changed as a result of the query made by said query unit, to change the setting of the job and then perform a logout, and, when the setting of the job is not to be changed as a result of the query made by said query unit, to restrict the logout.

Claims

1. An image processing apparatus comprising:

a detector unit configured to detect a logout event notified from a logged-in user;

a query unit configured to query, in a case where the detector unit detects the logout event while a job requiring an instruction from the logged-in user is being executed, the logged-in user whether or not to change a setting of the job under execution; and

a control unit configured to;

allow the logged-in user to log out of the image processing apparatus while the job continues to be under execution, in a case where the setting of the job is changed as a result of the query made by the query unit;

restrict the logged-in user from logging out of the image processing apparatus while the job continues to be under execution, in a case where the setting of the job is not changed as a result of the query made by the query unit; and

log out the logged-in user from the image processing apparatus without the query unit querying the logged-in user, in a case where the detector unit detects the logout event while a job not requiring an instruction from the logged-in user is being executed.

2. An image processing apparatus as claimed in claim 1, wherein the job is an interactive job that requires an instruction from the user after a start of execution of the job and before an end of the execution of the job.

3. An image processing apparatus as claimed in claim 2, wherein when the setting of the job is to be changed, the control unit changes the job into a non-interactive job.

4. An image processing apparatus as claimed in claim 1, wherein the job requiring the instruction from the user is a job for designing continuous scan.

5. An image processing apparatus as claimed in claim 1, wherein the job requiring the instruction from the user is an original preview job for checking a scanned original to proceed to the following processing.

6. An image processing apparatus as claimed in claim 1, wherein the job requiring the instruction from the user is a test copy job for checking a first one of a plurality of copies of printout and then outputting the remaining copies.

7. An image processing apparatus as claimed in claim 1, further comprising a notifying unit configured to notify the logged-in user that a logout processing is not executed, in a case where the setting of the job is not changed as a result of the query made by the query unit.

8. An image processing apparatus as claimed in claim 1, further comprising a display unit configured to display a warning screen, in a case where the detector unit detects the logout event while a job requiring an instruction from the logged-in user is being executed.

9. An image processing apparatus as claimed in claim 1, wherein the control unit allows the logged-in user to log out of the image processing apparatus while the job continues to be under execution, in a case where the setting of the job is changed as a result of the query made by the query unit, to allow the job to be changed to a job not requiring an instruction from the logged-in user.

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

a detection step of detecting a logout event notified from a logged-in user;

a query step of querying the logged-in user, in a case where the detecting step detects the logout event while a job requiring an instruction from the logged-in user is being executed;

control steps of;

allowing the logged-in user to log out of the image processing apparatus while the job continues to be under execution, in a case where the setting of the job is changed as a result of the query made in the querying step;

restricting the logged-in user from logging out of the image processing apparatus while the job continues to be under execution, in a case where the setting of the job is not changed as a result of the query made in the query step; and

logging out the logged-in user from the image processing apparatus without the query step querying the logged-in user, in a case where the detection step detects the logout event while a job not requiring an instruction from the logged-in user is being executed.

11. A non-transitory computer-readable storage medium storing a computer-readable program executable by a computer to execute a method of controlling an image processing apparatus, wherein the program comprises:

a detection module that detects a logout event notified from a logged-in user;

a query module for querying the logged-in user, in a case where the detection module detects the logout event while a job requiring an instruction from the logged-in user is being executed;

a control module that;

allowing the logged-in user to log out of the image processing apparatus while the job continues to be under execution, in a case where the setting of the job is changed as a result of the query made by the query module;

restricts the logged-in user from logging out of the image processing apparatus while the job continues to be under execution, in a case where the setting of the job is not changed as a result of the query made by the query module; and

logs out the logged-in user from the image processing apparatus without the query module querying the logged-in user, in a case where the detection module detects the logout event while a job not requiring an instruction from the logged-in user is being executed.
