The present invention addresses the problem that the road surface area allowed for projecting an image is limited, there is a restriction on the number of parts into which the image can be divided, and it is hard to achieve an intended visual effect even if individual images are sequentially projected. A control unit () controls three light sources (to) so that, among three individual images (to), projection of an image () to be projected second is started at a time point (t) later than a time point (t) at which a period of 250/3 milliseconds has elapsed from a projection start time point (t) for an image () to be projected first. Consequently, the visual effect of sequential projection of individual images is more easily achieved than when the projection of the second individual image () is started at the time (t).

[Problem] With prior art warning devices for vehicles, there is a risk of posing inconvenience to the driver, as well as a risk of the driver failing to notice a warning. [Means for Solving the Problem] This invention is provided with an image capture device (), a detection device (), an image processing device (), a primary warning device (), and a secondary warning device (). The image capture device () captures images of the surroundings of a vehicle (C). The detection device () detects vehicle information. The image processing device () detects target objects, such as pedestrians (P), from a fish-eye image (A) of an entire range of surroundings of a vehicle (C) captured by the image capture device (). If the image processing device () detects a target object, the primary warning device () displays the target object. If the image processing device () assesses that there is a high probability of contact between the vehicle (C) itself and the target object, the secondary warning device () transmits a sensory warning, such as a noise, vibration, or the like, to the driver. As a result, with this invention, a driver can be reliably prompted to use caution, without posing inconvenience to the driver.

This object detection device for the area around a vehicle is provided with an imaging device and an image processing device. The image processing device is configured from a detection area setting unit, three area processing units, and an integration processing unit. The detection area setting unit sets a trio of small, medium, and large detection areas within a one-frame image captured by the imaging device. Detection processing for the presence of objects within the trio of small, medium, and large detection areas is carried out for each detection area simultaneously and in parallel by the three area processing units using pattern matching. The integration processing unit integrates the plurality of detection results resulting from detection processing by the plurality of area processing units and outputs the result. As a result, the present invention makes it possible to reduce the amount of time required for detection processing.
