A vehicle-use roll-angle estimation system (10) includes an imaging device (40) and a roll-angle estimation device (20) which estimates a roll angle of the imaging device (40). The roll-angle estimation device (20) includes: a histogram generator (22) for generating a brightness gradient orientation histogram which indicates frequency distribution of brightness gradient orientation of a plurality of pixels contained in the image; and an estimation section (23) for identifying a brightness gradient orientation representing edges (Ev) in a vertical direction which indicate in the gravitational direction and a brightness gradient orientation representing edges (Eh) in a horizontal direction by utilizing the brightness gradient orientation histogram, and then estimating the roll angle by utilizing at least one of the identified brightness gradient orientation representing the vertical-direction edges and brightness gradient orientation representing the horizontal-direction edges.
