FIELD: information technology.
SUBSTANCE: invention relates to an image forming device. Result achieved by image forming apparatus which includes a control unit for performing insertion/removal of infrared cutoff filter into optical path and an imaging optical system; a reception unit for receiving a third command for instructing control unit of automatic control insert/tap filter infrared cut-off; and a determination unit configured to determine whether or not to include third command based on additional information receiving unit output; wherein when determination unit has determined that third command includes additional information, control unit controls insertion/withdrawal of filter infrared cutoff based on additional information, and when determination unit has determined that third command does not include additional information, control unit controls the insertion/withdrawal of infrared cutoff filter based on control information, which control unit has in advance.
EFFECT: wider range of technical capabilities of imaging device.
