PROBLEM TO BE SOLVED: To output a necessary log file when an error occurs, and to efficiently utilize respective filters.SOLUTION: When determining that processing by a filter ends normally (Yes at S1103), a job control part 402 of a server PC 106 which processes a filter pipeline comprising a plurality of filters determines a filter to be released (S1104), and releases the filter determined to be released (S1105). For example, the filter right before a filter determined to have ended normally is determined as the filter to be released, and then released. When determining that the processing by a filter does not end normally (No at S1103), the job control part determines a filter to output a log file (S1107) and makes the determined filter output the log file (S1108). |
