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.
