An image processing device (400) for deriving an inclination angle of an image, the device being provided with: an edge angle calculator (401) for calculating a plurality of edge angles corresponding to a plurality of pixels in the image by calculating an edge angle, which is the angle of an edge in each of the plurality of pixels; an available angle identification unit (402) for identifying one or more available angles, each of which is an edge angle and a potential inclination angle, by using the plurality of edge angles and a plurality of depth values, the depth values being values corresponding to the plurality of pixels and each representing the depth of the pixels; and an inclination angle derivation unit (403) for deriving an inclination angle from one or more of the available angles. |
