To provide a technique capable of preventing a background image from being updated to an inappropriate image and accurately detecting an object by a background subtraction method.SOLUTION: An object detection unit 11a detects a vehicle 2 located in a target area 10 by a background subtraction method by using a visible light frame image input to an image input unit 13 and obtained by capturing of the target area 10 and a background image of the target area 10 stored in a background image storage unit 12. A background image update unit 11b determines pixels on the frame image input to the image input unit 13, where the pixels are not used in updating the background image, based on a detection signal of a radio wave radar sensor 4 that irradiates the target area 10 with a search wave and detects the vehicle 2 located in the target area 10 based on a detected reflected wave, the detection signal being input to a detection signal input unit 14.SELECTED DRAWING: Figure 2
