A filter device according to the present invention comprises a filter processing section configured to execute a filtering process of data at arbitrary data positions included in a filtering region, the filtering process having a dependency on a filtering order and the execution per se of the filtering process of at least a part of the data and determine the execution of the filtering process at the arbitrary data positions, and a control section configured to control the filtering process executed by the filter processing section, wherein the control section makes the filter processing section execute the filtering process at a group of first data positions necessary to determine the execution of the filtering process at a second data position which is one of the arbitrary data positions, and the control section makes the filter processing section execute the filtering process at the second data position when the execution determination results obtained by the filter processing section at the group of first data positions are true.
