PROBLEM TO BE SOLVED: To provide a frame processor capable of reducing loads on a processor which relates to processing of unnecessary messages. SOLUTION: The frame processor comprises a message agreement comparator 2300 which uses a message that is received first as a reference message for comparison, and compares messages that are then received and classified with the reference message for agreement; and a redundant message decision part 2400 for deciding whether the agreed message, is the one that has been received or not. The redundant message decision part 2400 discards a message if an elapsed time since the reference message is received is within a decision reference value, and clears the reference message if the elapsed time exceeds the decision reference value.
