An image reading apparatus is connectable to an information processing apparatus having predetermined software and includes at least a processor and at least a memory coupled to the processor and having stored thereon instructions. The instructions are executed by the processor to act as a reading unit to perform scan processing for a document in a case where a read command transmitted from the information processing apparatus by user operation to the predetermined software is received, a detection unit to detect an error in the image reading apparatus, and a transmission unit to execute image data transmission processing for transmitting image data corresponding to the detected error in a case where the detected error is a first error, and execute error transmission processing different from the image data transmission processing in a case where the detected error is a second error.

An image processing apparatus includes: an image reading unit that reads an image of a document according to an instruction of an operator; an acquiring unit that acquires information on the operator performing document reading, or information on motions of the operator performed on the image processing apparatus in order to perform document reading; and a display that performs display for receiving an input for document reading, based on the line of sight, from the operator, when the information acquired by the acquiring unit satisfies a predetermined condition.

An image reading device includes a reading unit that reads a document sheet and a reading standard surface and outputs read values corresponding to pixels arranged in a main scan direction, a control unit that processes the read values, and a storage unit storing information to be referenced by the control unit. In the storage unit, first data that is read values of the reading standard surface and serves as standards, and second data on ranges of variation, based on a change in a temperature, in the read values are stored. The control unit determines, based on the first data and the second data read from the storage unit and third data obtained by reading the reading standard surface after an acquisition of the first data, whether an abnormality exists in the pixels.

A reading apparatus, having a document placement plate, a reader, a driving device, a cover, and a controller, is provided. The cover includes an alignment part and a protrusive part. The protrusive part includes an uneven surface and first and second edges forming outer edges of the uneven surface extending in a main scanning direction and in a sub-scanning direction, respectively. The controller is configured control the driving device to move the reader in the sub-scanning direction and the reader while being moved to read the protrusive part, and detect the first edge and the second edge in image data of the protrusive part read by the reader based on an image of the uneven surface and determine a reading range for the reader in the document placement plate based on positions of the first edge and the second edge.

An information processing apparatus includes a processor configured to, in a case where there are plural patterns of document areas extracted from an input image obtained by imaging documents, execute display control for displaying the plural patterns as options on a screen, receive selection of a correct pattern among the plural patterns according to the display of the screen through the display control, and extract an image of each document area included in the pattern selected by a user from the input image.

An image reading apparatus acquires first image data of a background portion stored in advance and read by a reading unit, acquires second image data by reading the background portion, generates third image data by increasing resolution of the first image data and fourth image data by increasing resolution of the second image data, detects an amount of shift of an image sensor relative to a lens array in a predetermined direction by shifting a specific pixel range of the fourth image data relative to the third image data and comparing the specific pixel range with the third image data, and compares fifth image data obtained by shifting the fourth image data in accordance with the shift amount with the third image data, so as to determine whether each of pixels included in the fifth image data is a defective pixel having an abnormal value.

An information processing apparatus includes a processor configured to: acquire a read image and item information, the read image being an image obtained by reading a paper medium including plural documents, the item information being information of plural items specified by a user from among plural items contained in the documents; extract plural character strings from the read image, each character string being associated with the corresponding one of the items included in the item information; in response to extracting the character strings associated with the item information from the read image, set a split position, the split position being a position at which to split out a portion of the read image as a set of documents, the portion being a portion of the read image from a page where the extracting has begun to a page containing the last extracted character string; and output the read image split in accordance with the split position.

In a reading device, a controller performs: detecting occurrence of a double-feed; executing a double-feed process; detecting a state of double-fed sheets; executing a first process when a command is inputted; and executing a second process when the command is not inputted. The double feed process includes: halting conveyance of an original document; and making notification of the occurrence of the double-feed. The first process performs, in accordance with the command, one of: resuming the conveyance of the original document; and quitting the conveyance of the original document. The second process performs, in accordance with a determination result, one of: resuming the conveyance of the original document; and continuing the halting and the making. The resuming is performed when the determination result indicates that the conveyance of the original document is possible. The continuing is performed when the determination result indicates that the conveyance of the original document is impossible.

Setting conditions related to reading of an image of a document are registered in association with a user according to input by a user. When a user is identified, the priority order is determined so that a setting condition corresponding to the identified user is prioritized over a setting condition not corresponding to the user among the registered setting conditions, and the setting condition information indicating the setting conditions in the determined priority is displayed. The image is read under the setting condition based on the setting condition information selected according to the input by the user of the setting condition information indicating the displayed setting conditions.

An image processing apparatus includes: a memory configured to store a machine-learned model produced by performing machine learning using teaching data associating image data generated by reading a document by an image reading device with device abnormality information on abnormality of the image reading device; and when the image reading device reads a document, a processor configured to obtain the device abnormality information based on generated image data and the machine-learned model.
