A scanner assembly (100) may include a housing (102) having abase (104) forming a cavity with an open top. Further, the housing (102) may include a platen (106) having a top surface (108) and a bottom surface (110). The bottom surface (110) may be attached to the base (104) around a periphery of the cavity. Furthermore, the housing (102) may include a bezel (112) adhered to the top surface of the platen (106) to cover an edge region of the top surface (108). The bezel (112) may include a bottom surface (114) having an inclined notch (116). Furthermore, the scanner assembly (100) may include a scanner module (118) movably disposed in the housing (102) below the platen (106). The scanner module (118) may be in an optical communication with the inclined notch (116) to detect a home position.

A print media detection apparatus may include a movable scanner bar for scanning media, a feeder tray for supplying the print media, a print media indicator and a controller. The print media indicator may include a first portion to interact with the print media within the feeder tray and a second portion coupled to the first portion to move in response to movement of the first portion. The scanner bar is to sense the second portion of the media indicator. The controller is to determine a characteristic of the print media within the feeder tray based upon sensing of the second portion by the scanner bar.

A verification apparatus includes a reading unit configured to read an image of a conveyed sheet. The apparatus obtains a reference image for verification of a sheet, and extracts, from the reference image, feature points to be used for alignment of an image with the reference image. The apparatus aligns, with the reference image, a read image obtained by reading an image of a verification target sheet by the reading unit, and verifies the read image by comparing the aligned read image with the reference image. Based on a number of the feature points extracted from the reference image the alignment is performed using positions of the feature points or using positions of sheet vertices each indicating a corner of the sheet.

A method for printing defect detection includes processing and analyzing a difference image obtained by comparing an image scanned with a verifier to a reference image. The detected defects are grouped, and the grouping is refined. Confidence level values are then assigned to the refined groups, and analysis is performed to determine if one or more servicing actions should be taken.

A predetermined image correction process is automatically performed on an image, and information for identifying that the predetermined image correction process has been performed is displayed in a state that an image having undergone the predetermined image correction process is being displayed.

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.

An image reading apparatus includes an image reading portion, a rotation processing portion, a recognition processing portion and an inclination detecting portion. The image reading portion reads an image of a sheet conveyed through a conveyance path. The rotation processing portion applies rotation processing to the image of the sheet read by the image reading portion to generate a plurality of comparative images each having a different angle with respect to the conveyance direction of the sheet. The recognition processing portion applies recognition processing to a symbol of each of the plurality of comparative images to determine a corresponding matching degree. The inclination detecting portion detects the inclination of the image of the sheet based on the matching degrees.

An image processing apparatus includes a medium discharge portion onto which a medium to be taken out by a person with the person standing is discharged, a placement portion that is installed above the medium discharge portion, an object in color that is represented by using a Y-value closer than a value that represents black color to a value that represents white color where the color is represented by using a Y-value that represents luminance in a YCbCr method being placed on the placement portion, an image capturing member that is installed above the placement portion and that captures an image of the object that is placed on the placement portion. Color of an upper portion of the placement portion is represented by using a Y-value closer than the value that represents the white color to the value that represents the black color where the color is represented by using the Y-value that represents the luminance in the YCbCr method such that the object and the placement portion are distinguishable from each other in the image that is captured by the image capturing member.

An image scanning device includes a casing, a paper feeding wheel, a transparent plate, a light bar, and an elastic support member. The transparent plate includes a first surface and a second surface, and the first surface faces the paper feeding wheel. The light bar is located on the second surface of the transparent plate and includes a plurality of light-emitting elements. A position at which the paper feeding wheel is tangent to the first surface defines a tangent position, a position at which the light-emitting elements are projected onto the first surface in a normal direction of the first surface defines a scanning position, and a scanning spacing exists between the tangent position and the scanning position. The elastic support member pushes the light bar and the transparent plate toward the paper feeding wheel. An image scanning equipment with an image scanning device is also provided.

An information processing apparatus includes a processor configured to acquire an image, receive designation of a type of the image, present another type specified from the image in a case where the type does not satisfy a criterion corresponding to the image, and receive re-designation of a type of the image.
