An imaging apparatus may include an infrared cutoff filter capable of being inserted into and extracted from an incident light path to an image sensing device, and may further include a first detecting unit configured to, when the infrared cutoff filter is off the incident light path to the image sensing device, detect whether the difference between current illuminance of a subject acquired from an image signal of the subject sensed by the image sensing device and a reference value of the illuminance of the subject determined after the infrared cutoff filter was extracted is equal to or greater than a first threshold value, and a filter control unit configured to, when the first detecting unit detects that the difference between the current illuminance and the reference value is equal to or greater than the first threshold value, insert the infrared cutoff filter into the incident light path.
