- controlling an amount of information to be used for object detection in a first information sensed by a first sensor on a basis of second information sensed by a second sensor;
- determining an imaging condition of the camera;
- and
- determining a target area to be used for object detection in a captured image by the camera on the basis of the second information, comprising:
- determining the target area from the captured image on a basis of information on at least one of a position, a speed, or a size of an object detected by the radar by using a threshold value.
