Abstract: In an object detection apparatus, an image obtaining part obtains, continuously in time, captured images captured by a vehicle-mounted camera capturing images of a vicinity of a host vehicle. A first detector detects an object by using the plurality of captured images obtained by the obtaining part at different time points. The first detector stores, as a template image, an area relating to the object detected by the first detector and included in one of the plurality of captured images that have been processed, in a memory. Moreover, a second detector detects an object by searching for a correlation area, having a correlation with the template image, included in a single captured image obtained by the image obtaining part.

Abstract: An object detection circuit detects an object moving in a periphery of a vehicle by a frame correlation method that uses a plurality of shot images captured at successive times. A state judgment part disables a detection function of the object detection circuit when a steering angle of an own vehicle is not in a prescribed steering angle range. Then, a condition changer changes the prescribed steering angle range corresponding to a condition of the steering angle in accordance with a velocity of the own vehicle. Therefore, the condition changer can relax the condition for enabling the detection function in accordance with the velocity of the own vehicle within a range where detection accuracy is ensured.

Abstract: An object detection circuit detects an object moving in a periphery of a vehicle by use of a shot image. A state judgment part changes a parameter relevant to a detection function so as to change whether the detection function of the object detection circuit is to be enabled or disabled while the object detection circuit is kept activated. Thus, even when the detection function of the object detection circuit is disabled, the object detection circuit is kept activated. Therefore, since there is no need to restart the object detection circuit in order to enable the detection function of the object detection circuit, a detection result by the object detection circuit is promptly obtained.
Abstract translation: 物体检测电路通过使用拍摄图像检测在车辆周边移动的物体。 状态判断部分改变与检测功能相关的参数，以便在对象检测电路保持激活的同时改变对象检测电路的检测功能是否被使能或禁用。 因此，即使当物体检测电路的检测功能被禁用时，物体检测电路也被保持激活。 因此，为了能够进行物体检测电路的检测功能，不需要重新启动物体检测电路，因此能够迅速地获得目标检测电路的检测结果。
