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： A reading device includes a visible light source to irradiate a subject with light having a visible wavelength; an invisible light source to irradiate the subject with light having an invisible wavelength; first and second image sensors to receive reflected light from the subject being irradiated with the light having the visible wavelength and the light having the invisible wavelength, and circuitry. The first image sensor generates visible image data containing a first invisible component, and the second image sensor generates invisible image data of a second invisible component. The circuitry removes the first invisible component contained in the visible image data using the invisible image data. The circuitry multiplies the invisible image data with the correction coefficient that absorbs an individual variation in removal of the first invisible component, and the correction coefficient is generated based on the visible image data and the invisible image.

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 image processing apparatus includes circuitry to receive visible image data obtained by reading of a subject with a sensor having sensitivity to visible light in a visible wavelength range and invisible image data obtained by reading of the subject with a sensor having sensitivity to invisible light in an invisible wavelength range. The circuitry generates image data for displaying, in a designated color, a portion of the visible image data corresponding to a designated region of the invisible image data. The designated region has an absorption rate equal to or higher than a predetermined absorption rate.

摘要： A sheet reading apparatus includes a sheet table on which a sheet is placed, a conveyor configured to convey the sheet, a reading guide configured to guide the sheet conveyed by the conveyor, and a reading device configured to read a shadow of the sheet conveyed by the conveyor, for detection of an inclination of the sheet. The sheet reading apparatus further includes a transparent member disposed at a position on a reading line of the reading device. The position on the reading line is withdrawn from the sheet and adjacent to the reading guide.

摘要： A reading device includes a light source, an image sensor, a background board, and an image processing circuitry. The light source irradiates visible light and invisible light to a subject. The image sensor receives the visible light and the invisible light, each of which is reflected from the subject, to capture a visible image and an invisible image. The background board is provided in an image capturing range of the image sensor. The background board is a background portion. The image processing circuitry detects a feature amount of the subject and the background portion from at least one of the visible image and the invisible image.

摘要： A reading device includes a first light source, a second light source, a first reading unit, a second reading unit, a comparison unit, and a correction unit. The first source irradiates an object to be read, with first light having a first transmittance to the object. The second source irradiates the object with second light having a second transmittance to the object. The first reading unit reads the first light from the object to output first image data. The second reading unit reads the second light from the object to output second image data. The comparison unit compares a data difference between the first and second image data. In a case where the data difference is equal to or larger than a threshold, the correction unit corrects data of an image area having the data difference equal to or larger than the threshold in the first or second image data.
