Abstract:
1. An image input/output apparatus executing an image input/output process and comprising: a first storing unit adapted to store log information representing an internal state of the image input/output apparatus during an execution of the image input/output process; a fault detecting unit adapted to detect a fault occurring during the execution of the image input/output process; a second storing unit adapted to store an occurrence frequency of the fault detected by said fault detecting unit in a way that associates the occurrence frequency with the fault; a determining unit adapted to determine whether or not the occurrence frequency of the fault is equal to or larger than a threshold value; and a log management unit adapted to control the storage setting for fault-related log information representing an internal state of the image input/output apparatus on the basis of a determining result produced by said determining unit and selectively store the fault-related log information in said first storing unit on the basis of the storage setting, wherein, when said determining unit determines that the fault occurrence frequency fluctuates from a count (a number of times) less than the threshold value to a count equal to or larger than the threshold value, said log management unit changes the storage setting to storing the fault-related log information with regard to the image input/output process to be executed next.
