An image processing apparatus comprises: an acquiring unit configured to acquire image data generated by reading an original; a specifying unit configured to specify an object region including a predetermined object in the image data; a removing unit configured to remove, from the object region, noise with a size smaller than a size specified by a first threshold; and a setting unit configured to set the first threshold, for each object region specified by the specifying unit, in accordance with the size of the object region.

Image processing apparatus, image processing method, and non-transitory computer-readable storage medium storing program comprising acquiring an image generated by reading an original, and removing noise from an object region with a size smaller than a size specified in a first threshold

An image capturing unit captures an image including an embedded image that is printed on the basis of image data in which at least a color component has been modulated according to additional information. An adjustment unit adjusts a white balance of the image captured by the image capturing unit on the basis of an adjustment value associated with the embedded image. A processing unit processes image data of the image captured by the image capturing unit whose white balance has been adjusted by the adjustment unit to read the additional information in the image captured by the image capturing unit.

An apparatus includes a generation unit and a multiplexing unit. The generation unit generates image data for recording by a forming apparatus that forms an image on a forming member using a print head that applies energy to the member. The multiplexing unit performs multiplexing processing to generate recording data in which predetermined information to be recognized by a reading apparatus as information different from an image to be recorded on the member is embedded in the image data.

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.

To make it possible to easily extract additional information from printed matter by using a built-in camera of a mobile terminal. An information processing apparatus that reads additional information by capturing printed matter in which the additional information is embedded by using a built-in camera, including: a control unit configured to acquire a first captured image obtained by capturing the printed matter under a first image capturing condition and a second captured image obtained by capturing the printed matter under a second image capturing condition different from the first image capturing condition; and an extraction unit configured to extract the additional information by analyzing the first captured image and the second captured image.

Information processing apparatus, control method thereof, and storage medium

An image processing method includes: a first obtaining step of obtaining data of an image; a second obtaining step of obtaining additional information; a third obtaining step of obtaining information related to a printable area of a print medium on which the image based on the data obtained in the first obtaining step is printed; determining step of determining a position where the obtained additional information is embedded in the image on the basis of the information obtained in the third obtaining step; and embedding step of embedding the additional information with reference to the determined position.

A drawing unit configured to draw a print target content is instructed to draw a content and a predetermined element. Based on a notification from the drawing unit, which corresponds to the drawing instruction and has been made regardless of completion of drawing to the instruction, drawn data is acquired from the drawing unit. If the acquired data includes the predetermined element, a print apparatus is caused to execute printing based on the acquired data. If the acquired data includes no predetermined element, data is acquired from the drawing unit again without causing the print apparatus to execute printing based on the acquired data.

A recording apparatus performs recording on a recording medium by using a tray having a plurality of slots, and includes a reception unit receiving information for specifying a detection position of the recording medium in a slot of the tray from an external apparatus, and a specification unit to specify the detection position. In addition, a control unit controls the recording apparatus so that, in a case where the recording medium is arranged in a first slot and no recording medium is arranged in a second slot, recording processing is performed on the recording medium arranged in the first slot, and recording processing is not performed in association with the second slot. Detection processing to detect a recording medium is not performed for a third slot which is not specified, and detection processing is performed for the first and second slots which are specified.
