FIELD: physics.
SUBSTANCE: in a detection sensitivity control module (50), which controls detection sensitivity such that it increases according to the level (U) of white haziness, detection sensitivity of a vehicle detector (70) (a module for executing an image recognition application), which detects another vehicle (6) (a moving object), present in the surrounding region of the vehicle (5), with predetermined detection sensitivity from an image obtained by an imaging module (10) situated in the vehicle (5) configured to observe the surrounding region of the vehicle (5) through a lens (12) and convert the light signal of the observed surrounding region of the vehicle (5) into an image signal, is corrected based on the adhesion level M of a substance, such as dirt or water droplets, stuck to the lens (12), which is calculated by an adhesion level computing module (26).
EFFECT: accurate detection of a moving object from an image, even when the lens is dirty.
