摘要： An image reading device and an image forming apparatus. The image reading device includes an image reader to read an image of a document, and a color reference component arranged to face the image reader. In the image reading device, the image reader reads the color reference component at a prescribed timing to obtain color reference image data, and correction data generating processes are executed based on the obtained color reference image data to generate correction data used to correct data of the image read by the image reader. In the image reading device, wherein the color reference component is moved relative to the image reader in a direction orthogonal to a direction toward and away from the image reader. The image forming apparatus includes the image reading device, and an image is formed on a recording material based on data of the image read by the image reading device.

摘要： An image processing apparatus includes circuitry to: obtain a read image read from an image of a document output from an image reading device; detect an edge between a background area and a document area in the read image; sample a detection result of the edge at each first interval in a first direction to extract a first boundary point group including a plurality of boundary points; sample the detection result of the edge at each second interval in the first direction to extract a second boundary point group including a plurality of boundary points; determine a noise removal condition based on the first boundary point group; remove, from the second boundary point group, a boundary point satisfying the noise removal condition as noise; and calculate a linear equation approximating the second boundary point group from which the noise is removed.

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; detect a second boundary between the object and the shadow of the object in the image information; and detect an inclination of the object in the image information from the first boundary and the second boundary detected by the processing circuitry.

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.
