Patent ID: 8707309

Claim:
An image processing apparatus comprising a processor capable of executing plural types of periodic processings to be repetitively executed periodically, the image processing apparatus comprising: a processor; a first input unit configured to input a first execution time interval indicating which indicates an execution interval of a first type of periodic processing; a second input unit configured to input a second execution time interval which is different from the first execution time interval and which indicates an execution interval of a second type of periodic processing; and an execution unit configured to, in a case where the second execution time interval is input by the second input unit after the first execution time interval is input by the first input unit, (1) start both the first type of periodic processing and the second type of periodic processing at a next start time for the first type of periodic processing if the next start time for the first type of periodic processing is earlier than a next start time for the second type of periodic processing, and (2) start both the first type of periodic processing and the second type of periodic processing at the next start time for the second type of periodic processing if the next start time for the second type of periodic processing is earlier than the next start time for the first type of periodic processing, wherein, after both the first type of periodic processing and the second type of periodic processing are started by the execution unit, the first type of periodic processing is repetitively executed periodically according to the first execution time interval and the second type of periodic processing is repetitively executed periodically according to the second execution time interval.
