Abstract: An object detection device is configured to be mounted to an own vehicle to detect an object present around the own vehicle. The object detection device includes a coordinate acquisition section and an object recognition section. The coordinate acquisition section acquires position coordinates of a detection point corresponding to the object on the basis of a plurality of images captured at different positions along with movement of the own vehicle by one imaging section mounted to the own vehicle. The object recognition section recognizes the object without using position coordinates of a movement point that is a detection point corresponding to a moving object but using position coordinates of a stop point that is a detection point different from the movement point.

Abstract: A control device to be applied to a vehicle equipped with an imaging device, a ranging device, and a safety device is configured to, based on moving-object detection information around the vehicle acquired from images captured by the imaging device, perform a first actuation process directed to moving objects to actuate the safety device, and based on stationary-object detection information around the vehicle acquired from measurements made by the ranging device, perform a second actuation process directed to stationary objects to actuate the safety device. In the control device, a mask region setting unit is configured to set at least either neighborhood-of-stationary-object regions or far-side regions as a mask region. An actuation restriction unit is configured to, in response to the moving object determined to be present around the vehicle being present in the mask area, restrict performance of the first actuation process on the moving object.

Abstract: A moving object determination device applied to a vehicle, the device includes at least a predicted time calculation unit, a time difference calculation unit, and a moving/stationary determination unit. The predicted time calculation unit calculates a predicted time from when an obstacle starts to be detected by the first sensor to when the obstacle will no longer be detected by the second sensor based on a traveling speed of the obstacle and a length of the obstacle. The time difference calculation unit calculates a real time from when the obstacle has been detected by the first sensor to when the obstacle has no longer been detected by the second sensor, and calculates a time difference between the real time and the predicted time. The moving/stationary determination unit determines that the obstacle is a stationary object in response to the time difference being equal to or greater than a predetermined value.

Abstract: An exposure control device of a vehicle-mounted camera comprises an illuminance level determination unit, a plurality of timers, a timer operating unit, and an exposure level determination unit. The illuminance level determination unit determines that an illumination level of an external light illuminance corresponds to one of a plurality of illuminance levels. The timers each provided for a corresponding one of a plurality of change modes, the change modes being defined among the plurality of illuminance levels, or among a plurality of exposure levels for an exposure of a vehicular camera. The timer operating unit operates each of the timers in accordance with a state of change of the illuminance level of the external light illuminance. The exposure level determination unit determines one of the exposure levels for the exposure of the vehicular camera based on a count state of each of the timers.

Abstract: A control device to be applied to a vehicle equipped with an imaging device and a safety device is configured to, based on moving-object detection information detected from images captured by the imaging device, actuate the safety device for a moving object.
In the control device, a control unit is configured to, in response to any of certain information that it is certain that the object is a moving object and uncertain information indicating that it is not certain whether the object is a moving object being acquired as moving-object detection information, actuate the safety device based on a position of the object subjected to detection with the certain information or the uncertain information. An actuation region setting unit is configured to, when the moving-object detection information is the uncertain information, narrow an actuation region as compared to when the moving-object detection information is the certain information.-
