Abstract
An imaging apparatus includes an illumination unit, an imaging unit, an illumination control unit, a target detection unit, a radiation illuminance, and a comparison unit. The illumination unit emits infrared light. The imaging unit captures an image of an object. The illumination control unit controls an illumination intensity of the illumination unit for irradiating the object. The target detection unit detects at least a portion of a human body contained within an irradiation range of the illumination unit. The radiation illuminance calculation unit calculates a radiation illuminance of the illumination unit with respect to the portion of the human body detected by the target detection unit. The comparison unit compares the radiation illuminance calculated by the radiation illuminance calculation unit with a predetermined threshold value. The illumination control unit controls the illumination intensity of the illumination unit based on a comparison result of the comparison unit.
