摘要: An inclination detecting device includes processing circuitry. The processing circuitry is configured to detect, in image information that is an image of an object imaged by an imaging device at an imaging position where a background member forms a background, a first boundary between the background member and a shadow of the object at detection positions in at least one of main-scanning and sub-scanning directions on an outline of the object; detect a second boundary between the object and the shadow of the object at detection positions in at least one of the main-scanning and sub-scanning directions on the outline of the object in the image information; detect a boundary group including detection results of the second boundary at the detection positions; and detect an inclination of the object in the image information from detection results of the first boundary, the second boundary, and the boundary group.

摘要: An edge detecting device includes processing circuitry. The processing circuitry is configured to acquire first color information and second color information in an image including a document region and a background region outside the document region. The first color information is color information of the background region and the second color information is color information of the document region. The processing circuitry is configured to detect a boundary between the background region and the document region from a change in color information between the first color information and the second color information.
