Abstract: Luminous values of pixels of coordinates previously set as an obstacle presence line are inputted to a memory as a one-dimensional signal converted from a two-dimensional image signal taken by a camera. A portion of the line has a luminous value other than a luminous value predicted as a luminous value of a normal road. The portion of the line is then extracted as a vehicle candidate range. Further, based on characteristic of the vehicle such as a vehicle width or a relative speed, presence or absence of the vehicle is determined by removing noise from the extracted vehicle candidate range.

The extract unit calculates the feature values for each pixel of the original image using the pixel evaluation model, and defines the extractive area that includes the characteristic portion based on the feature values.
