A rotational movement component of a camera provided on a mobile object is to be detected in a precise and simple manner. Three motion vectors extracted from the forward images captured by a camera mounted on a vehicle are extracted on a random basis. A temporary rotation angle is calculated using the extracted motion vectors based on a relational expression that represents the relationship between a background vector and the rotation angle of the camera, the relational expression being a linear expression of the yaw angle, pitch angle, and roll angle of the rotational movement of the camera. An error when using the temporary rotation angle is calculated for other motion vectors, and the number of motion vectors for which the error is within a predetermined threshold value is counted. After repeating such a process for a predetermined number of times, the temporary rotation angle with the largest number of motion vectors for which the error is within the predetermined threshold value is selected as the rotation angle of the camera. The present invention can be applied to an in-vehicle obstacle detecting device.
