Abstract
In an apparatus for monitoring surroundings of a vehicle carrying the apparatus, a corresponding-point displacement calculator sets a search region for corresponding points in a plurality of images of an object captured simultaneously from different positions and calculate a displacement value between the corresponding points. A search region modifier modifies the search region if a number of corresponding-point displacement values acquired by the corresponding-point displacement calculator within a predetermined period of time is less than a predetermined threshold. An image displacement calculator calculates an image displacement value that is an amount of displacement between the plurality of images based on the corresponding-point displacement values acquired within the predetermined period of time if the number of corresponding-point displacement values acquired by the corresponding-point displacement calculator within the predetermined period of time is equal to or greater than the predetermined threshold. A displacement corrector corrects for an image displacement based on the image displacement value.
