An image inspection apparatus includes a processor configured to acquire printing data that is data as a base of an image to be printed, acquire read data that is data obtained by reading the image printed on a paper sheet, perform correction of a blur caused by floating of the paper sheet occurring in the reading of the image, on the read data, and inspect the image by comparing the printing data with the read data after the correction.

An image reading apparatus includes a transport section that can transport original documents along a transport path, a reading section configured to read images of the original documents transported by the transport section, an output controller configured to output data of the original documents read by the reading section, a multi-sheet feed detection sensor configured to detect a multi-sheet feed of the original documents transported by the transport section, and an instruction section configured to issue an instruction to disable multi-sheet feed detection by the multi-sheet feed detection section.

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 sheet feeding device includes a sheet tray, a blower, a feeder, an illuminator, an imager, and circuitry. The sheet tray stacks sheets. The blower blows air to the sheets stacked on the sheet tray and floats an uppermost sheet of the sheets. The feeder feeds the uppermost sheet. The illuminator illuminates the uppermost sheet floating. The imager captures an image including the uppermost sheet illuminated by the illuminator. The circuitry adjusts an imaging condition based on the image captured by the imager.

The present disclosure provides an image forming apparatus capable of improving usability in a configuration where information related to sheet size is detected automatically, and a control method thereof. A control unit is configured to execute a determination process if the control unit acquires a detection result of a size of a sheet supported on a sheet support portion by a size detection unit in a state where a first information related to a size of a sheet and a second information related to a type of a sheet that satisfy a predetermined combination condition are stored in the storage portion. The control unit determines in the determination process whether the detection result of the size of the sheet satisfies the combination condition with respect to the second information stored in the storage portion, and changes a successive procedure depending on a result of the determination process.

A reading device includes a reading unit configured to read a document, and a control unit configured to acquire image data including a document region and a background region from the reading unit. The control unit acquires document information about a document, and sets, based on the document information, a background range indicating a range of a luminance value regarded as the background region.

An image reading system includes an image reading apparatus including a transport unit configured to transport a document from a bundle of cut documents one by one, a reading unit configured to read an image of the transported document, and a reading control unit, and an external control unit included in an external device coupled to the image reading apparatus, wherein an inclination correction process that corrects an inclination of the image of the document, a size determination process that determines a size of the image as a standard for the bundle of documents, and a size correction process that corrects the size of the image of the document to a specific size determined by the size determination process are performed.

An image reading apparatus includes a document setting table, an image data generation unit, a downsized image data generation unit, a document information generation unit, and an image cropping unit. The image data generation unit reads a plurality of source documents placed on the document setting table and generates image data representing the plurality of source documents. The downsized image data generation unit generates downsized image data by reducing a size of the image data. The document information generation unit analyzes the downsized image data to detect respective positions of the plurality of source documents and generate document information indicating the detected positions. The image cropping unit cuts out a plurality of regions from the image data according to the document information and acquires a plurality of items of cropped image data respectively representing the plurality of source documents.
