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.

An image forming apparatus includes an image forming unit, an intermediate transfer member, a transfer member, a power source, a fixing unit, a photo sensor photosensor, and a control unit configured to perform a mode to output a test chart which is formed by transferring a plurality of test toner images from the intermediate transfer member onto a plurality of sheets of the recording material, the test chart being used to adjust the transfer voltage applied to the transfer member. The control unit is configured to adjust the transfer voltage based on a detection result of the photo sensor photosensor detecting the plurality of test toner images recovered fixed on the recording material. In a case where a jam occurred during execution of the mode, the control unit is configured to resume the mode after the jam has been recovered.

An image processing apparatus includes a platen, a fixed-document detection unit, a determination unit, and a processing-target selection unit. The determination unit determines whether the document on the platen is a left document or not when the document on the document tray and the document on the platen are detected, upon acceptance of the document-reading-starting instruction by the instruction accepting unit. The processing-target selection unit sets image data obtained by a conveyed-document reading unit as a processing target when the determination unit determines that the document on the platen is the left document, and inquires which image data obtained by the conveyed-document reading unit and a fixed-document reading unit, to be set as the processing target of the user when the determination unit determines that the document on the platen is not the left document.

The present disclosure provides a technique to obtain a tilt state occurring between an image capturing unit and a print image having additional information embedded in it without using the visible image. In the technique, an image of a print image in which additional information having a specified frequency characteristic is embedded is captured using an image capturing unit to obtain captured image data. A frequency analysis is performed on partial image data corresponding to a specified area in the obtained captured image data, to obtain distance information on a distance between the specified area and the image capturing unit. Inclination information indicating a state of a relative inclination between the image capturing unit and the print image is obtained based on this distance.

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.

An information processing apparatus includes an acquisition unit, notification control unit, input unit, and extension unit. The acquisition unit acquires a measurement result obtained by measuring a printing medium characteristic and acquires a characteristic reference range of each of printing media types set in advance to identify a type of a measured printing medium. Extracting, as a candidate printing medium and based on the acquired measurement result and the acquired characteristic reference range, a type of printing medium using the characteristic reference range including the measurement result and notifying information indicating the type of the candidate printing medium are performed. The input unit inputs information, wherein a type of printing medium on which recording is to be performed by the recording unit has a first reference range which is the characteristic reference range of the type and corresponds to the input information. The extension unit extends the first reference range.

A surface object comprises a surface with a boundary, the surface having a background color. At least one optical marker is provided on the surface for assisting of image processing for improving appearance of an image of the surface with the boundary. At least one optical marker includes at least one color which is lighter or darker than the background color and the color different ΔE between the background color and the at least one color of the optical marker being between ΔE=2 and ΔE=18.

An information processing apparatus includes a light emitting unit and a light receiving unit for receiving light output from the light emitting unit, and includes a detection unit for outputting a light reception signal indicating that the light receiving unit has received light from the light emitting unit, a driving signal output unit for outputting a driving signal to the detection unit so that the light emitting unit intermittently outputs light, a detection signal output unit for outputting, based on the output driving signal and the output light reception signal, a detection signal indicating whether an object exists between the light emitting unit and the light receiving unit, and a control unit including an interrupt port to which the output detection signal is input and for returning from a power saving state in response to the detection signal being input to the interrupt port in the power saving state.

An image forming apparatus according to an embodiment includes a paper supply unit. An image forming unit forms an image on paper supplied from the paper supply unit. A reading unit generates image information by reading an original document, the generated image information corresponding to the original document. An input unit receives input designation of a memo region in the generated image information. A control unit determines a color of the original document based on the generated image information. The image forming unit forms a memo image in the designated memo region on the paper supplied from the paper supply unit with a color different from the determined color of the original document.

A multifunction peripheral (MFP), which successively conveys a plurality of documents stacked on a document tray and reads the document, determines whether there is a difference among sizes of the plurality of documents in response to at least one of the documents being read by a scanner, in a case where a preview operation of a read image is performed, notifies a user of a possibility that documents having different sizes are mixed and read based on a result of the determination, enables a function of performing reading corresponding to respective document size of mixed size documents in which documents having different sizes are mixed, and provides navigation for prompting re-reading of the document.
