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.

A printing apparatus includes a hardware processor and a printer. The hardware processor is configured to set a temporary base coat region which is a region where a base coat is to be applied, set a temporary design region which is a base design region and which includes an outer shape corresponding to a bounding polygon of the temporary base coat region, detect a base coat region of a nail where the base coat is applied, and adjust the temporary design region so that an outer shape of the temporary design region matches the outer shape of a bounding polygon of the base coat region, set a portion of the adjusted temporary design region overlapping with the base coat region as a design region, and generate design printing data. The printer prints a design on the nail based on the design printing data.

A captured image is obtained in which an adapter tray is captured which is fitted in a predetermined first area in a conveyance tray conveyed by a printing apparatus and has a second area fitted with a printing medium on which printing is performed by the printing apparatus. A shape of the second area is specified based on the captured image and information about the predetermined first area. Further, an image based on the specified shape of the second area is output.

A printing system 1 configured to perform various settings of a printer 5 via a web browser 3 wherein the printer 5 is configured for selection and setting a type and a size of the sheet 7 via the web browser 3 and an operation panel 9 of the printer 5 is configured to enable selection and setting, for among predetermined types, a type of the sheet 7 that was placed in the sheet placed section 11 of the printer 5. The operation panel 9 is provided so that a document icon 13, a photograph icon 15, and an envelope icon 17 can be visually recognized.

An image reading apparatus includes a transparent member having a placement surface on which a document is to be placed, a reading unit configured to read an image of the document placed on the transparent member via the transparent member, and a reading mode in which an image of a document, placed in a holding member with a transparent portion, is read. The document to be read is placed in the holding member so as to be visible via the transparent portion and the holding member is placed on the placement surface with the transparent portion of the holding member in contact with the placement surface. A processor detects an edge in an image acquired by the reading unit in the reading mode, and to extract an image surrounded by an edge detected in an area surrounded by an edge corresponding to the holding member in the reading mode.

An image forming apparatus includes an image forming device that forms an image on a sheet and an image reading device that conveys a document placed on a stacking portion and reads an image on the document. The image forming device outputs first and second output materials in succession. First output material constitutes a first type of sheet having a predetermined pattern image, and the second output material constitutes a second type of sheet having the predetermined pattern image. The image reading device conveys the first and second output materials in succession from the stacking portion and reads a first image and a second image. A first parameter to cause image formation using the sheet of the first type is acquired based on the first image and a second parameter to cause image formation using the sheet of the second type is acquired based on the second image.

An image processing apparatus includes a selection unit, a determination unit, and a control unit to set candidates to be selected by the selection unit. If determination unit determines that there is not a set of a size and an orientation of a document of which the orientation cannot be correctly determined, the control unit sets, as selection unit selection candidates, candidates of sets of sizes and orientations of a plurality of documents. If the determination unit determines that there is a set of a size and an orientation of a document of which the orientation cannot be correctly determined, the control unit sets, as selection unit selection candidates, candidates obtained by excluding the set of the size and the orientation of the document of which the orientation cannot be correctly determined from the candidates of the sets of the sizes and the orientations of the plurality of documents.

This image forming apparatus (100) is equipped with: a document set detector (3a, S1, S5); a document size detector (3a, S2, S3, S5); a manual feeder (6) with a manual feed tray (61) that is not equipped with a sensor for detecting the size of set manually-fed paper; a printer (5) that performs printing on the basis of image data; an operation panel (4) that receives setting for feeding paper from the manual feeder (6); and a controller (7) that recognizes the size of a set document and performs manually-fed-paper automatic setting for recognizing the recognized size of the set document as the size of the manually-fed paper.
