Abstract:
A multi-function peripheral device serving as a peripheral device of an information processing device and having a plurality of functions including a scanner function for retrieving an image from a document, the multi-function peripheral device using multitask processing to execute at least a first task, which uses the scanner function, simultaneously with at least a second task, the multi-function peripheral device comprising:a simultaneous operation determination unit that determines, repeatedly at one of timing of switching tasks and at an integral multiple of the timing of switching tasks, whether the first task using the scanner function is being performed simultaneously with the second task; anda retrieval speed control unit that reduces retrieval speed of the scanner function when the simultaneous operation determination unit determines that the first task using the scanner function is being performed simultaneously with the second task and that does not reduce said retrieval speed of the scanner function when the simultaneous operation determination unit determines that the first task using the scanner function is not being performed simultaneously with the second task.
