Abstract: A caution-required feature detector in a projection control apparatus detects a caution-required feature that is a feature with a solid shape that impacts on traveling of a subject vehicle. An optical illusion image generating unit generates an optical illusion image that recalls the solid shape of the caution-required feature. An alert determination unit determines whether alerting the caution-required feature is necessary. A projection controller causes a projector to project the optical illusion image at a position corresponding to a position of the caution-required feature determined as requiring the alert.
