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.

The first image data is converted into the second image data defined by a color space that depends on an output apparatus that outputs image data. Additional information is multiplexed on the converted second image data by using a multiplex parameter.

Information processing apparatus, information processing method, and non-transitory computer-readable storage medium storing program

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.

Information processing apparatus to process captured image data, information processing method, and storage medium

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.

An image in which additional information is embedded is shot by an imaging unit. The additional information embedded in the image is acquired from the shot image. When the additional information cannot be acquired, a display unit is caused to display information that prompts a user to move the information processing apparatus. The additional information embedded in the image is acquired from an image shot after the information that prompts the user to move the information processing apparatus is displayed.
