An image reading apparatus includes a read size determination circuit. The read size determination circuit has a plurality of operation mode including a first mode and a second mode. The first mode determines the size of the document detected by the first document reading unit as a first read size and determines a read size of the document set in advance as a second read size. The first read size is the read size of the document when the first document reading unit reads the document. The second mode determines the size of the document detected by the first document reading unit as the first read size. If the second document reading unit reads the document, the second mode determines the read size of the document set in the setting screen as the second read size when a start instruction of a reading job is entered using the operation circuit.

According to the technology of the present disclosure, candidates of a selection-type value included in metadata in a key-value format, which is registered in association with scanned image data, can be appropriately displayed. An information processing apparatus, which assigns metadata in a key-value format to scanned image data obtained by scanning a document, includes: a first obtaining unit configured to obtain a character string extracted from the scanned image data; a second obtaining unit configured to obtain a template of the metadata; a display control unit configured to display a screen for inputting the metadata; and a setting unit configured to set a value in association with the scanned image data, based on operation by a user via the screen, the value corresponding to a key included in the template of the metadata obtained by the second obtaining unit.

An information processing apparatus includes a processor configured to: set a rule for specifying a region in which a value of an item of an attribute assigned to a form shown by an image is shown in the image for each item, from a predetermined first rule, a second rule indicating an arrangement of the region for an element included in the form, which is input by a user, and a third rule indicating coordinates of the region in the image, which are input by the user; and extract the value of the item shown in the region specified by using the set rule.

A non-transitory computer-readable medium stores computer-readable control program instructions configured to, when executed, cause an information processing device to obtain an image file, store the image file in association with related information, generate a file path for the image file, the file path including a plurality of virtual directories based on the related information, the plurality of virtual directories belonging to respective different hierarchical layers, and in response to receiving, from browser program instructions stored in the information processing device, a request for one or more virtual directories belonging to a first lower layer that is hierarchically one level lower than a specified virtual directory in a top layer, retrieve and send the one or more virtual directories to the browser program instructions, thereby enabling the browser program instructions to display the retrieved one or more virtual directories belonging to the first lower layer.

A recording medium conveyance device includes a storage, a conveyer that conveys a conveyed object, an ultrasonic sensor that outputs a value indicating an attenuation amount of an ultrasonic wave caused by the conveyed object, and a hardware processor. The hardware processor executes a type detection process of detecting a type of the conveyed object based on output of the ultrasonic sensor and storing the type in the storage and an overlay detection process of detecting whether the conveyed object is in an overlay state in which a gap is present based on output of the ultrasonic sensor, and switches to either one of the type detection process and the overlay detection process. The hardware processor executes the type detection process when the type is not stored in the storage and executes the overlay detection process when the type is stored in the storage.

An image processing apparatus according to the present disclosure is an image processing apparatus for automatically transmitting a document file by using a result of a character recognition process on a scan image of a document as a property, and includes: at least one processor that executes the program to perform: extracting a confidence factor indicating a degree of certainty of the result of the character recognition process; in a case where the extracted confidence factor is above a predetermined threshold value, determining that the document file using the result of the character recognition process as the property is allowed to be automatically transmitted; and setting the predetermined threshold value such that an incorrect transmission ratio of document files to be automatically transmitted reaches a target incorrect transmission ratio.

An image reading apparatus includes an image sensor to read a document, a sensor to detect whether the document is loaded on the image reading apparatus, and a processor to, when the sensor detects the document is loaded on the image reading apparatus, and before a scan instruction is input to the image reading apparatus, control the image sensor to execute a pre-scan job with respect to the loaded document using a default set value.

An information processing apparatus capable of reducing troublesome work of a user when converting an image obtained by newly scanning a business form to a file. An information processing apparatus that sets, when converting the image to a file, a file name of the image. A preview image of the scanned original is displayed, and user selection of a character area on the preview image is detected. An item name candidate area is extracted based on location information of the character area selected by the user on the preview image, and a character string included in the item name candidate area is set as an item name of a character string included in the character area selected by the user. The set item name is displayed as a file name rule such that the set item name is selectable by the user.

According to one embodiment, an image reading device includes a scanner configured to read documents that have a plurality of pages and generate image data for each page scanned. A display unit displays the preview images based on the image data from the scanner. An input unit is configured to receive input operations from a user. A controller is configured to cause the display unit to display preview images for pages of a document. The preview images are initially displayed as selected preview images or non-selected preview images according to whether the page corresponding to the preview image satisfies a filter condition or not. Each displayed preview image is selectable and deselectable by an input operation received via the input unit. The controller is further configured to generate a file including image data for the pages corresponding to the selected preview images.

A method and an apparatus for filtering a wireless signal by parsing a wireless signal transmitted from a surrounding wireless terminal so as to extract channel information of the surrounding wireless terminal in a MAC frame and performing adaptive filtering on the wireless signal.
